Detailed Description

The present application is described in further detail below with reference to the drawings and examples. It is specifically noted that the following examples are only for illustration of the present application, but do not limit the scope of the present application. Likewise, the following embodiments are only some, but not all, of the embodiments of the present application, and all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present application.

Reference in the present application to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. Those of skill in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

In this application, the electronic device 10 may be a terminal device with a sound emitting function, such as an earphone or a smart glasses. The electronic device 10 may include a deck module 11 and a support assembly 12, the support assembly 12 being connectable with the deck module 11 to support the deck module 11 in a worn position. Wherein, the movement module 11 may generate mechanical vibration under the action of the excitation signal, and the mechanical vibration may be transmitted to the user based on at least one of the bone conduction mode and the air conduction mode. Further, in connection with fig. 1, the support assembly 12 may be configured to be supported on the user's ear in a worn state, and further to be wrapped behind the user's brain. The number of the movement modules 11 may be two, and the two movement modules 11 are respectively connected with two ends of the support assembly 12 one by one. Of course, in other embodiments, the support assembly 12 may be configured to be supported on the user's ears, bridge of the nose, etc. in the worn state, and may be configured to bypass the user's crown in the worn state, as is not shown. The wearing position may be a position of the cheek of the user near the ear, a position of the ear away from the head, or other physiological positions, which are not described herein.

As an example, in connection with fig. 2 and 3, the deck module 11 may include a case assembly 111, a transduction device 112, and a vibration panel 113. Wherein the transduction device 112 is arranged to generate mechanical vibrations under the influence of an excitation signal and is arranged within the housing assembly 111; the vibration panel 113 is connected to the transduction device 112 and serves to indirectly abut against or directly contact with the skin of the user to transmit the aforementioned mechanical vibration.

Further, the deck module 11 may include a face component 114 connected to at least the vibration panel 113, for example, the face component 114 covers the vibration panel 113, so that the vibration panel 113 contacts the skin of the user through the face component 114 to give consideration to both the sound quality and wearing comfort of the electronic device 10.

As an example, referring to fig. 2 and 3, the deck module 11 may include a first vibration transmitting plate 115, and the transduction device 112 may be connected to the case assembly 111 through the first vibration transmitting plate 115. In this way, compared to the transducer 112 being directly fixed in the housing assembly 111, it is beneficial to avoid excessive transmission of mechanical vibration generated by the transducer 112 to the housing assembly 111, thereby reducing the leakage of the movement module 11. The transduction device 112 may include a support 1121, a second vibration-transmitting sheet 1122, a magnetic circuit system, and a coil 1123, where the support 1121 may be connected to the housing assembly 111 through the first vibration-transmitting sheet 115, the magnetic circuit system may be connected to the support 1121 through the second vibration-transmitting sheet 1122, and the coil 1123 may be connected to the support 1121 and extend into a magnetic gap of the magnetic circuit system. In this way, the energized coil 1123 generates an ampere force, i.e., a mechanical vibration, in the magnetic field of the magnetic circuit system, which causes the support 1121 to move relatively with respect to the magnetic circuit system. Further, the magnetic circuit system may include a magnetically conductive cover 1124 and a magnet 1125, and the magnet 1125 may be fixed to a bottom of the magnetically conductive cover 1124 and form the magnetic gap with a sidewall of the magnetically conductive cover 1124. The number of magnets 1125 may be one or more, such as two magnets shown in fig. 2 and 3, and two adjacent magnets 1125 are disposed with the same poles opposite to each other and may sandwich a magnetic conductive plate therebetween, so that the magnetic induction lines of the magnets 1125 pass through the coil 1123 more. In some embodiments, the magnetic circuit system may include a fastener 1126, where the fastener 1126 may fix the plurality of magnets 1125 stacked and the magnetic conductive plate sandwiched between the magnets 1125, for example, to connect the second vibration-transmitting sheet 1122, the magnets 1125, and the bottom of the magnetic conductive cover 1124 together. Of course, in other embodiments, the magnet 1125 may be fixed to the bottom of the magnetic shield 1124 by glue.

As an example, referring to fig. 2 and 3, the face component 114 may include a face sleeve 1141, and the face sleeve 1141 may cover the vibration panel 113, for example, the face sleeve 1141 may be connected to the vibration panel 113 by an adhesive medium 1142, which is beneficial to increase the flatness of the face sleeve 1141 on the vibration panel 113 and to increase the synchronicity of the face sleeve 1141 with the vibration panel 113 during vibration. Wherein the adhesive medium 1142 may be configured to allow the entire face component 114 to be removed from the vibration panel 113 without damaging the face component 114 and the vibration panel 113. Thus, the face component 114 is not only convenient for users to replace when in need due to being detachable, but also is free from cracking due to being removable as a whole, thereby being beneficial to reducing the difficulty of the face component 114 in being detached from the core module 11 and further improving the portability of the face component 114 replacement.

As an example, the bonding medium 1142 may be disposed such that the peel force between the sleeve 1141 and the vibration panel 113 is between 4N and 12N. If the peeling force is too small, i.e. the adhesive force is too small, the flatness of the sleeve 1141 on the vibration panel 113 is easily insufficient and the synchronism with the vibration panel 113 is poor; if the aforementioned peeling force is too large, i.e., the adhesive force is too large, it is liable to cause difficulty in removing the entirety of the face component 114 from the vibration panel 113.

As an example, the peel force between the bonding medium 1142 and the sleeve 1141 may be greater than the peel force between the bonding medium 1142 and the vibration panel 113. As such, the bonding medium 1142 is more prone to be peeled off along with the face component 114 rather than remaining on the vibration panel 113 during removal of the face component 1141 from the vibration panel 113, i.e., the risk of adhesive residue on the vibration panel 113 is reduced, to facilitate replacement of a new face component 114. Wherein the material of the bonding medium 1142 is more prone to be similar to the sleeve 1141 in order to increase the adhesion between the bonding medium 1142 and the sleeve 1141.

As an example, the adhesive medium 1142 may be double sided tape or cured glue. The adhesive layers on the front and back sides of the double-sided adhesive tape can be designed differently according to the material of the face sleeve 1141 and the vibration panel 113, and the material of the adhesive can be similar to the material of the face sleeve 1141. Further, the skin sleeve 1141 may have a hardness less than that of the vibration panel 113, and the adhesive medium 1142 may have a hardness less than that of the vibration panel 113. The material of the vibration panel 113 may be polycarbonate or at least one of glass fiber and carbon fiber mixed therein, and the material of the face sleeve 1141 may be silica gel, rubber, or the like. Therefore, the glue can be silica gel type soft glue.

As an example, the ratio between the area of the bonding medium 1142 and the area of the vibration panel 113 may be between 0.8 and 1, for example, the bonding medium 1142 may be applied to the entire vibration panel 113 (commonly referred to as "full-fit"), and for example, the bonding medium 1142 may be in a grid shape. If the aforementioned ratio is too small, the flatness of the sleeve 1141 on the vibration panel 113 is liable to be insufficient and the synchronism with the vibration panel 113 during vibration is liable to be poor. Notably, are: the area of the sleeve 1141 is generally larger than the area of the vibration panel 113, and if the area of the adhesive medium 1142 is larger than the area of the vibration panel 113, the area of the portion of the adhesive medium 1142 that is not in contact with the vibration panel 113 is not counted as the area of the adhesive medium 1142. Further, the ratio between the thickness of the bonding medium 1142 and the thickness of the sleeve 1141 may be between 0.4 and 1.2. If the aforementioned ratio is too small, the adhesive force provided by the adhesive medium 1142 is liable to be insufficient; if the aforementioned ratio is too large, it may easily result in excessive loss of mechanical vibration generated by the transducer 112 during transmission through the sleeve 1141 and the bonding medium 1142. Further, the thickness of the bonding medium 1142 may be less than the thickness of the sleeve 1141. Notably, are: in embodiments in which the thickness of a portion of the sleeve 1141 that is connected to the vibration panel 113 through the adhesive medium 1142 is not equal to the thickness of another portion of the sleeve 1141 that is not connected to the vibration panel 113, the thickness of the sleeve 1141 may specifically refer to the thickness of the portion of the sleeve 1141 that is connected to the vibration panel 113 through the adhesive medium 1142 (e.g., the body portion 11411 mentioned later) when calculating the ratio or magnitude relationship between the thickness of the adhesive medium 1142 and the thickness of the sleeve 1141.

It should be noted that: the electronic device 10 may include several pairs of the face component 114 to facilitate a user's replacement of a new one when needed. The adhesive medium 1142 may be fixed to the sleeve 1141 in advance, that is, the adhesive medium 1142 and the sleeve 1141 are integrated. The side of the adhesive medium 1142 adhered to the vibration panel 113 may be provided with release paper so as to maintain the adhesiveness of the adhesive medium 1142, and a user may tear off the release paper thereon when replacing the new face component 114. Of course, in other embodiments, the bonding medium 1142 may be independent of the sleeve 1141.

As an example, referring to fig. 2-4, the face component 114 may include a stiffening member 1143 coupled to the face sleeve 1141, the stiffening member 1143 having a hardness greater than the hardness of the face sleeve 1141 to increase the structural strength of the portion of the face component 114. For example: the material of the face sleeve 1141 is silica gel, rubber, etc., the material of the reinforcing member 1143 is polycarbonate or at least one of glass fiber and carbon fiber mixed therein, and the two are formed into an integrally formed structural member by an injection molding process. Wherein, the face component 114 may be detachably connected with the shell component 111 through the reinforcement member 1143, so as to avoid the edge area of the face component 114 from colliding with the shell component 111 during the process that the face component 114 follows the vibration panel 113 to vibrate. In other words, the middle region and the edge region of the face component 114 may be detachably connected with the vibration panel 113 and the case component 111, respectively. Accordingly, the face component 114 and the housing component 111 define a cavity that houses at least the transducer 112 and the vibration panel 113. Of course, in other embodiments where the edge region of the sleeve 1141 has a sufficiently large safety gap with the housing assembly 111, the sleeve 114 may not include the stiffening member 1143, and thus the edge region of the sleeve 1141 may not be connected to the housing assembly 111. Further, in other embodiments, such as where the face component 114 does not require replacement, the face component 114 may be configured to be non-removable.

In some embodiments, housing assembly 111 may include a deck housing 1111, with an end of deck housing 1111 being open, transducer 112 may be positioned at least partially within deck housing 1111, and vibration panel 113 may be positioned at least partially outside deck housing 1111. Wherein the stiffening member 1143 may be at least partially disposed within the open end of the engine housing 1111 and may be removably coupled to the engine housing 1111 such that there is a bond between the face component 114 and the housing component 111.

In some embodiments, the housing assembly 111 may include a deck housing 1111 and a deck cover 1112 covering the open end of the deck housing 1111, the transducer 112 may be located at least partially within the deck housing 1111, and the vibration panel 113 may be located at least partially outside the deck housing 1111, i.e., the face component 114 and the transducer 112 may be located on opposite sides of the deck cover 1112, respectively. Accordingly, the deck cover 1112 is provided with a first escape hole 11121 that allows the vibration panel 113 to be connected to the transduction device 112. The reinforcement member 1143 may be at least partially located outside the engine casing 1111 and may be detachably connected to the engine cover 1112, so that there is a certain bonding force between the face component 114 and the casing component 111.

Further, the transducer 112 and the bottom of the deck casing 1111 may be spaced apart in the direction of vibration of the transducer 112 (e.g., the direction indicated by arrow D1 in fig. 3) to reduce the risk of collision with the bottom of the deck casing 1111 when the transducer 112 vibrates. In some embodiments, the bottom of the transducer 112 and the bottom of the deck 1111 may be spaced apart from each other by a certain distance in the vibration direction of the transducer 112, so that the thickness of the deck 1111 may be ensured to meet the requirements, and meanwhile, under the extreme working conditions such as dropping and collision of the deck module 11.

As an example, in connection with fig. 5 to 8, one of the open end of the cartridge housing 1111 and the flange portion 11432 may be provided with a snap protrusion 11111, the other one may be provided with a snap recess 11434 for receiving the snap protrusion 11111, and the snap protrusion 11111 is embedded in the snap recess 11434, i.e. the two cooperate such that the reinforcement member 1143 and the cartridge housing 1111 are detachably connected, simply and reliably. Wherein the number of snap protrusions 11111 may be multiple, such as the four shown in fig. 8; the number of snap recesses 11434 may be equal to the number of snap protrusions 11111, such as the four shown in fig. 6, and one-to-one.

As an example, referring to fig. 5 and 6, the stiffening member 1143 may include an annular body portion 11431 and a flange portion 11432 connected to the annular body portion 11431, and the sleeve 1141 may be connected, e.g., injection molded, with at least the annular body portion 11431. The number of flange portions 11432 may be plural, for example, four as shown in fig. 6, and the plurality of flange portions 11432 are provided at intervals in the circumferential direction of the annular main body portion 11431. Accordingly, the flange portion 11432 is detachably connected to the deck housing 1111 to achieve the detachable connection of the reinforcement member 1143 to the deck housing 1111. Further, the stiffening member 1143 may include a protruding portion 11433 connected to the annular body portion 11431, and the sleeve 1141 may be further connected to the protruding portion 11433, which is advantageous for increasing the connection area between the sleeve 1141 and the stiffening member 1143, thereby increasing the bonding strength of the two. The number of the protruding portions 11433 may be plural, for example, eight as shown in fig. 6, and the plurality of protruding portions 11433 are arranged at intervals in the circumferential direction of the annular main body portion 11431, for example, the plurality of flange portions 11432 and the plurality of protruding portions 11433 are arranged at intervals alternately in the circumferential direction of the annular main body portion 11431.

Further, the ratio between the covered area of the stiffening member 1143 covered by the sleeve 1141 and the surface area of the stiffening member 1143 may be greater than or equal to 0.8, for example, the annular body portion 11431 and the protruding portion 11433 are all covered by the sleeve 1141 to increase the connection area between the sleeve 1141 and the stiffening member 1143 as much as possible.

As an example, referring to fig. 2 and 3, and fig. 5 and 6, the sleeve 1141 may include a body 11411, a transition portion 11412, and a coating portion 11413 integrally connected, the body 11411 and the coating portion 11413 may be offset from each other in the vibration direction D1, an orthographic projection of the coating portion 11413 on a reference plane perpendicular to the vibration direction D1 surrounds an orthographic projection of the body 11411 on the reference plane, that is, the coating portion 11413 is located at an outer periphery of the body 11411, and the transition portion 11412 connects the body 11411 and the coating portion 11413. The main body 11411 may be connected to the vibration panel 113 through an adhesive medium 1142, and the coating portion 11413 may cover the reinforcing member 1143, for example, at least the annular main body 11431. Further, the wrapping portion 11413 may be closer to the transducer 112 than the main body portion 11411 in the vibration direction D1, so that the vibration panel 113 is in contact with the skin of the user through the main body portion 11411. In addition, in embodiments where the sleeve 1141 is provided with a communication hole 11414, for example, the communication hole 11414 is provided on the transition portion 11412, it is also advantageous to avoid the communication hole 11414 being covered by the skin of the user.

Further, the transition 11412 may be provided in a curved shape in a reference cross section (e.g., paper surface) parallel to the vibration direction D1 to increase the deformability of the transition 11412, which is advantageous in avoiding the vibration of the vibration panel 113 from being limited by the housing assembly 111, especially in an embodiment in which the middle region and the edge region of the face component 114 are connected to the vibration panel 113 and the housing assembly 111, respectively. In the extending direction from the main portion 11411 to the covering portion 11413, the transition portion 11412 may gradually approach the transducer 112 and gradually get away from the transducer 112, or the transition portion 11412 may gradually approach the transducer 112 and then be parallel to the plane of the first vibration-transmitting plate 115.

As an example, the margin of activity of the transition 11412 in the vibration direction D1 may be greater than or equal to the maximum amplitude of the transduction device 112. The play margin may be a displacement amount when the transition portion 11412 is deformed from a curved shape to a straight shape.

As an example, referring to fig. 2 and 3, and fig. 5 to 8, the open end of the deck housing 1111 may be provided with a communication hole 11112, the communication hole 11112 being located between two adjacent flange portions 11432 in the circumferential direction of the annular body portion 11431, the communication hole 11112 communicating the inside and outside of the deck module 11 via a passage between the corresponding two flange portions 11432. Here, since the number of the flange portions 11432 may be plural, for example, four as shown in fig. 6, the number of the communication holes 11112 may be plural, for example, four as shown in fig. 7 and 8, that is, the communication holes 11112 may correspond to the aforementioned passages one by one. Thus, although the movement casing 1111 will generally form the first leakage sound in the far field under the driving action of the transducer 112, the air in the cavity formed by the surrounding of the face component 114 and the casing component 111 forms the second leakage sound in the far field under the action of the transducer 112 and via the communication hole 11112 and the channel, and the phase of the second leakage sound and the phase of the first leakage sound (near) are opposite, for example, the difference between the absolute value of the phase of the second leakage sound and the absolute value of the phase of the first leakage sound is smaller than 60 °, so that the two can be opposite to each other in the far field, which is beneficial to reducing the leakage sound of the movement module 11 in the far field. Notably, are: the communication hole 11112 may be a complete through hole at the open end where the deck casing 1111 is provided, or may be a notch at the open end of the deck casing 1111.

Further, the sleeve 1141 may be provided with a communication hole 11414, e.g. the communication hole 11414 is provided on the transition 11412. The function of the communication hole 11414 is the same as or similar to that of the communication hole 11112, and will not be described here. Notably, are: in the embodiment in which the communication hole 11112 is provided only to reduce the leakage of the movement module 11 in the far field, the sleeve 1141 may not be provided with the communication hole 11414, which is advantageous in preventing sweat and the like from entering the electronic device 10. Similarly, in the embodiment in which only the communication hole 11414 is provided to reduce the leakage of the deck module 11 in the far field, the communication hole 11112 may not be provided at the open end of the deck housing 1111 to simplify the structure of the deck housing 1111.

The inventors of the present application found during long-term development that: although the second leakage is beneficial to reducing the leakage of the movement module 11 in the far field, the frequency response curve of the second leakage is relatively turbulent, so that the second leakage has a certain optimization space. To this end, in connection with fig. 2 and 3, the case assembly 111 may include a deck cover 1112 covering an open end of the deck case 1111, and the face assembly 114 and the transducer 112 may be disposed on opposite sides of the deck cover 1112, respectively, the deck cover 1112 being provided with a first escape hole 11121 allowing the vibration panel 113 to be connected to the transducer 112. The cavity formed by the face component 114 and the shell component 111 may be divided into two parts by the core cover 1112, that is, the first cavity is formed by the core cover 1112 and the core shell 1111 in a matching manner, and the second cavity is formed by the face component 114 and the shell component 111 in a matching manner, for example, the first cavity and the second cavity are respectively located at two opposite sides of the core cover 1112. Further, the transducer 112 may be at least partially disposed in the first cavity, and the vibration panel 113 may be at least partially disposed in the second cavity. Correspondingly, the movement module 11 is provided with a channel for communicating the second cavity with the outside of the movement module 11, so as to allow the air in the first cavity to form a third leakage sound in the far field under the action of the transducer 112 and via the channel, and the phase of the third leakage sound and the phase (near) of the first leakage sound are opposite, for example, the difference between the absolute value of the phase of the third leakage sound and the absolute value of the phase of the first leakage sound is smaller than 60 °, so that the two can be opposite and cancel in the far field, which is beneficial to reducing the leakage sound of the movement module 11 in the far field. So, under the restriction effect of the core cover 1112, the air in the first cavity can be restricted to enter and exit the core module 11 to a certain extent, which is favorable for avoiding the excessive turbulence of the frequency response curve of the leakage sound which is opposite to the first leakage sound in the far field, thereby increasing the sound leakage reducing effect of the core module 11. Based on the helmholtz resonator, the area of the channels may be as large as possible, for example, by increasing the number of the channels, and further, for example, by increasing the aperture of each of the channels, so that the resonant frequency of the third leakage sound is shifted to a frequency band with a higher frequency (for example, a frequency range greater than 4 kHz) as much as possible, which is beneficial to further avoiding that the third leakage sound is heard by the user.

As an example, the number of the above-mentioned passages may be plural, which is advantageous in increasing the area of the above-mentioned passages. Wherein, a plurality of the channels can be all arranged on any one of the structural components of the face sleeve 1141, the reinforcing member 1143, the core shell 1111, etc.; the plurality of passages may be partially provided in one of the constituent members of the sleeve 1141, the reinforcing member 1143, the cartridge case 1111, and the like, and partially provided in the other of the constituent members of the sleeve 1141, the reinforcing member 1143, the cartridge case 1111, and the like.

Further, for any one of the above-described passages, the above-described passage may be formed at least by any one of the following embodiments.

In some embodiments, such as where the stiffening member 1143 is at least partially located within the open end of the cartridge housing 1111, the channel may be at least partially provided on the stiffening member 1143. For example: the flange portion 11432 and the interval region between the adjacent two flange portions 11432 are both located in the open end of the deck case 1111, the interval region between the adjacent two flange portions 11432 constitutes a part of the above-described passage, and the communication hole 11112 constitutes another part of the same passage. For another example: the flange portion 11432 and the space between two adjacent flange portions 11432 are both located in the open end of the deck housing 1111, there is an assembly gap between the face component 114 and the deck housing 1111, the space between two adjacent flange portions 11432 constitutes a part of the above-mentioned passage, and the assembly gap between the face component 114 and the deck housing 1111 constitutes another part of the same passage.

In some embodiments, for example, the stiffening member 1143 is located at least partially within the open end of the cartridge housing 1111, and the channel may be located at least partially within the open end of the cartridge housing 1111. For example: the open end of the deck housing 1111 is provided with a communication hole 11112, and the side of the face component 114 contacting the deck cover 1112 is provided with an uneven surface, such as a wavy surface with a height, so that at least part of the reinforcement 1143 does not contact the deck cover 1112 to form a predetermined gap. Also, there is an assembly gap between the face component 114 and the deck casing 1111, a reserved gap between the face component 114 and the deck cover 1112, and an assembly gap between the face component 114 and the deck casing 1111 constitute a part of the above-mentioned passage, and the communication hole 11112 constitutes another part of the same passage. For another example: the open end of the deck housing 1111 is provided with a communication hole 11112, and there is an assembly gap between the face component 114 and the deck housing 1111 and the deck cover 1112, the communication hole 11112 forming a part of the above-mentioned passage, and the assembly gap between the face component 114 and the deck housing 1111 and the deck cover 1112 forming another part of the same passage.

In some embodiments, the channels may be provided on the sleeve 1141, such as with the communication holes 11414 as the channels.

In some embodiments, for example, the stiffening member 1143 is at least partially located outside the open end of the cartridge housing 1111, and the above-described passage may be provided only on the stiffening member 1143, for example, the space between the adjacent two flange portions 11432 is at least partially located outside the open end of the cartridge housing 1111, and the space between the adjacent two flange portions 11432 may be used as the above-described passage.

In some embodiments, for example, the stiffener 1143 is at least partially located within the open end of the cartridge housing 1111, and the channel may be at least partially disposed at the open end of the cartridge housing 1111, for example, the communication hole 11112 may be used as the channel, and at least part of the stiffener 1143 may not contact the cartridge cover plate 1112, so that the first cavity may communicate with the communication hole 11112 via a gap between the stiffener 1143 and the cartridge cover plate 1112.

As an example, in connection with fig. 3, the above-mentioned passage may be provided such that a gas flow direction (for example, a direction indicated by an arrow D2 in fig. 3) between the above-mentioned second chamber and the outside of the deck module 11 intersects with the vibration direction D1, for example, an extending direction of the above-mentioned passage is not directed toward a side of the deck module 11 facing the skin of the user in the wearing state. In this way, it is advantageous to avoid that the channel is covered by the skin of the user, so that the third leakage is better counteracted with the first leakage in the far-field anti-phase.

As an example, referring to fig. 2 and 3, the deck 1112 may include an inner top 11122, a connecting portion 11123, and an outer bottom 11124 integrally connected, the inner top 11122 and the outer bottom 11124 being offset from each other in the vibration direction D1, an orthographic projection of the outer bottom 11124 on a reference plane perpendicular to the vibration direction D1 surrounding an orthographic projection of the inner top 11122 on the aforementioned reference plane, that is, the outer bottom 11124 is located at a periphery of the inner top 11122, and the connecting portion 11123 connects the inner top 11122 and the outer bottom 11124. Wherein the outer bottom portion 11124 can be coupled to the housing assembly 111 such that the outer bottom portion 11124 is closer to the transducer 112 than the inner top portion 11122 in the vibration direction D1 to facilitate avoiding the communication hole 11112 in the cartridge housing 1111. Accordingly, in conjunction with fig. 4, a first relief aperture 11121 may be provided on the inner top 11122.

As an example, referring to fig. 2 and 3, the case assembly 111 may include a sealing film 1113 coupled to the deck cover 1112, the sealing film 1113 being provided with a second escape hole 11131 allowing the vibration panel 113 to be coupled to the transduction device 112, the second escape hole 11131 having a smaller aperture than the first escape hole 11121, and the sealing film 1113 being used to seal an assembly gap of the first escape hole 11121. The assembly gap refers to a gap between a structure formed by connecting the vibration panel 113 and the transducer 112 and a wall surface of the first avoiding hole 11121, and the assembly gap can prevent the vibration panel 113 and/or the transducer 112 from colliding with the deck cover 1112. So, under the restriction effect of core apron 1112 and sealing membrane 1113, the air in the aforesaid first cavity can be furthest by the restriction to go into and go out core module 11, is favorable to further avoiding excessively derangement with the frequency response curve of the leak sound that above-mentioned first leak sound looks in the far field opposite phase looks to increase core module 11's leak sound effect that falls. In addition, since the sealing film 1113 is provided, the aperture of the first escape hole 11121 can be made larger, which is advantageous in further avoiding the aforementioned collision. Accordingly, the vibration panel 113 may be coupled to the bracket 1121 through the second escape hole 11131 and the first escape hole 11112.

As an example, referring to fig. 2 to 4, the sealing film 1113 may include a first connection portion 11132, a folded ring portion 11133, and a second connection portion 11134 integrally connected, and the folded ring portion 11133 connects the first connection portion 11132 and the second connection portion 11134. Wherein, the rigidity of the first connection portion 11132 and the second connection portion 11134 may be greater than the rigidity of the hinge portion 11133, respectively, for example, the first connection portion 11132 and the second connection portion 11134 are respectively disposed in a ring shape and the hinge portion 11133 is disposed in a U-shape in a cross-section on a reference cross-section parallel to the vibration direction D1, so that the first connection portion 11132 and the second connection portion 11134 can relatively move in the vibration direction D1. Accordingly, the second escape hole 11131 may be provided on the second connection portion 11134, that is, the first connection portion 11132 is located at the periphery of the second connection portion 11134. At this time, the first connection part 11132 may be connected to the deck cover 1112, and the second connection part 11134 may be connected to the vibration panel 113 or the transduction device 112 to seal the assembly gap of the first escape hole 11121.

In some embodiments of the present application,the sealing film 1113 is a complete film structure. It should be noted that in other embodiments of the present application, the sealing membrane 1113 may be provided with at least one micro-hole, for example, the area of the micro-hole is less than or equal to 2mm ² The pressure difference between the inside and the outside of the first cavity is reduced while the sealing membrane 1113 is used for further optimizing the sound leakage reduction, i.e. the micropore can play a role in pressure relief. Of course, the sealing film 1113 may not have micro holes, and the assembly gaps between the respective structural components when the first cavity is formed after the assembly of the structural components such as the cartridge case 1111, the cartridge cover 1112, and the sealing film 1113 may play a role in pressure relief.

Further, the sealing film 1113 may be made of rubber, silica gel, or the like.

Further, the collar 11133 protrudes in the vibration direction D1 in a direction away from the transducer 112, i.e. the collar 11133 protrudes into the first cavity. In this way, droplets, dust, etc. that have entered the first chamber through the passage are less likely to accumulate on the collar 11133 than if the collar 11133 were to protrude into the second chamber, thereby maintaining the reliability of the sealing film 1113.

As an example, in conjunction with fig. 2 and 3, 9 and 10, the bracket 1121 may include a first bracket 11211, a second bracket 11212 and a suspension 11213. Wherein, the first bracket 11211 may be connected to the central region of the first vibration-transmitting sheet 115, for example, both may be formed into an integrally formed structural member through a metal insert injection molding process; the second bracket 11212 may be connected to a peripheral region of the second vibration-transmitting sheet 1122, and the suspension 11213 may be connected to a central region of the second vibration-transmitting sheet 1122, for example, three of which may be integrally formed as a structural member through a metal insert injection molding process. Further, one of the first and second brackets 11211, 11212 may be provided with a socket 11214, and the other may be provided with a socket 11215 for receiving the socket 11214, the socket 11214 being embedded within the socket 11215 so that the first and second brackets 11211, 11212 are connected. The number of the plugging posts 11214 and the plugging holes 11215 may be plural, and they correspond to each other one by one, for example, four as shown in fig. 9. Accordingly, the magnetic circuit is connected to the suspension 11213, for example, the fastening member 1126 connects the bottoms of the suspension 11213, the magnet 1125 and the magnet housing 1124 together, or the suspension 11213, the magnet 1125 and the magnet housing 1124 are adhered together by adhesive; the coil 1123 may be connected to the second bracket 11212, and the sealing film 1113 may be connected to at least one of the first bracket 11211 and the vibration panel 113.

In some embodiments, such as fig. 9, the first bracket 11211 may include a body portion 11216 and a socket portion 11217 connected to the body portion 11216, and the socket portion 11217 may be disposed in a column shape and at least partially embedded within the vibration panel 113 such that the vibration panel 113 is connected to the bracket 1121. Accordingly, the socket post 11214 may be provided on the second bracket 11212 and the socket hole 11215 may be provided on the body portion 11216.

In some embodiments, such as fig. 10, the first bracket 11211 may include a body portion 11216 and a socket portion 11217 connected to the body portion 11216, and the socket portion 11217 may be provided in a cylindrical shape, with the vibration panel 113 partially embedded in the socket portion 11217, such that the vibration panel 113 is connected to the bracket 1121.

As an example, referring to fig. 2 to 4, at least one of the vibration panel 113 and the bracket 1121 may be provided with a support end surface corresponding to a surrounding area of the second escape hole 11131, on which the sealing film 1113 is fixed, simply and reliably. Wherein, for the embodiment shown in fig. 9, the aforementioned support end surface may be provided at least on the vibration panel 113; in the embodiment shown in fig. 10, the support end surface may be provided at least on the bracket 1121, for example, an end surface of the connector 11217 not connected to the main body 11216 may be a support end surface.

As an example, referring to fig. 2 to 4, the bracket 1121 may be provided with a first support end surface 11218, for example, the first support end surface 11218 is an end surface of the socket portion 11217 not connected to the main body portion 11216, the vibration panel 113 may be provided with a second support end surface 1131, and the first support end surface 11218 and the second support end surface 1131 may collectively sandwich the second connection portion 11134. In other words, the vibration panel 113 and the support end surface of the bracket 1121 facing each other sandwich the second connection portion 11134 in common. In this way, when the vibration panel 113 is connected to the bracket 1121, the sealing film 1113 can be further pressed against the bracket 1121, which is simple and reliable, and can achieve two purposes.

As an example, referring to fig. 4, a side of the deck 1112 facing away from the transduction device 112 may be provided with a recess 11125, the first escape hole 11121 may be provided at a bottom of the recess 11125, and the first connection portion 11132 may be connected to the bottom of the recess 11125 and surround the first escape hole 11121. Thus, the recessed area 11125 not only can play a role in positioning during the assembly process of the sealing film 1113 and the movement cover plate 1112, but also can increase the flatness of the cavity wall surface of the first cavity. Accordingly, recessed region 11125 may be disposed on inner top 11122.

Further, the recessed region 11125 may include a first recessed section 11126 and a second recessed section 11127, the first recessed section 11126 being closer to the transduction device 112 than the second recessed section 11127 in the vibration direction D1, a dimension of the second recessed section 11127 in a direction perpendicular to the vibration direction D1 being larger than a dimension of the first recessed section 11126 in a direction perpendicular to the vibration direction D1. In short, the recessed area 11125 is divided into two sections in the vibration direction D1, and the first escape hole 11121 is provided at the bottom of the first recessed section 11126. Wherein the first connection 11132 is secured to the bottom of the first recessed segment 11126.

In some embodiments, the first connecting portion 11132 may be connected to the bottom of the first recessed segment 11126 by double-sided adhesive, and the second recessed segment 11127 contains glue, which is beneficial to increase the reliability of the connection between the sealing film 1113 and the movement cover 1112. In other words, the sidewall of the second recess 11127 and the first connection portion 11132 cooperate to form an annular glue container, which is beneficial to avoiding glue overflow.

In some embodiments, first connection 11132 may be connected to the bottom of first recessed segment 11126 by glue. Alternatively, in some embodiments, the first connection 11132 may be connected to the second recessed segment 11127 by glue.

Based on the above-described related description, the first connection portion 11132 may be fixed on the bottom of the first recessed section 11126 by the first colloid 11135, so that the sealing film 1113 is connected to the deck 1112; the second connection portion 11134 may be fixed to an end surface of the socket portion 11217 (i.e., the first support end surface 11218) that is not connected to the main body portion 11216 by the second adhesive 11136, so that the sealing film 1113 is connected to the bracket 1121. Wherein the vibration panel 113 may further press the sealing film 1113 against the bracket 1121. Further, the first colloid 11135 and the second colloid 11136 may be double-sided tape or glue, respectively. Notably, are: when the first and second colloids 11135 and 11136 are double-sided tapes, respectively, they may be pre-fixed on the sealing film 1113, respectively; when the first glue 11135 and the second glue 11136 are glue, they may be pre-fixed to the deck 1112 and the bracket 1121, respectively. Further, the first support end face 11218 and the bottom of the first recessed section 11126 may be flush in the vibration direction D1 regardless of the machining error, the assembly error, and the like.

As an example, referring to fig. 2 and 3, and fig. 7 and 8, the cartridge case 1111 may include a first cylindrical sidewall 11113 and a first annular base 11114 connected to an inner wall surface of the first cylindrical sidewall 11113, the outer bottom 11124 may be supported on the first annular base 11114, and the reinforcement 1143 may be located between the inner wall surface of the first cylindrical sidewall 11113 and an outer wall surface of the connection portion 11123. Accordingly, one of the snap protrusion 11111 and the snap recess 11434 may be disposed on the first cylindrical sidewall 11113, and the other may be disposed on the stiffener 1143. For convenience of description, the fastening protrusion 11111 or the fastening groove 11434 provided on the first cylindrical sidewall 11113 may be further defined as a fastening portion, that is, the fastening portion may be provided on an inner wall surface of the first cylindrical sidewall 11113, so that the face component 114 is in snap fit with the fastening portion through the flange portion 11432. Similarly, the communication hole 11112 may be provided on the first cylindrical sidewall 11113. Further, the deck cover 1112 may press the edge region of the first vibration-transmitting plate 115 against the first annular base 11114.

Further, a plurality of posts 11115, such as six posts shown in fig. 8, may be disposed on the first annular base 11114, and the deck 1112 may be supported on the first annular base 11114 and may be in plug-in fit with the posts 11115, where the posts 11115 serve as positioning means at least during assembly of the deck 1112 with the deck 1111. Accordingly, the outer bottom 11124 can be supported on the first annular bearing platform 11114 and can be in a socket fit with the upright 11115. Wherein, the plurality of posts 11115, the plurality of fastening portions (for example, fastening protrusions 11111, which will not be described further below), and the plurality of communication holes 11112 may be disposed at intervals in the circumferential direction of the first cylindrical sidewall 11113, and the plurality of fastening portions and the plurality of communication holes 11112 may be staggered from each other in the circumferential direction of the first cylindrical sidewall 11113, so that the three are reasonably distributed. Further, at least two of the plurality of posts 11115 and at least two of the plurality of communication holes 11112 may at least partially overlap in a one-to-one correspondence in the circumferential direction of the first cylindrical sidewall 11113 such that the posts 11115 are located between two adjacent snaps.

Illustratively, the upright 11115 may be a heat stake to further secure the deck 1112 to the first annular deck 11114. The pillars 11115 shown in fig. 2, 3, 7 and 8 are in a form before being melted, and generally do not exceed the corresponding communication holes 11112 after being melted, so as to avoid interference with the air entering and exiting the first cavity.

As an example, in connection with fig. 7 and 8, the housing assembly 111 has a long axis (e.g., the direction indicated by the arrow D3 in fig. 8) and a short axis (e.g., the direction indicated by the arrow D4 in fig. 8) perpendicular to the vibration direction D1, and the dimension of the first annular bearing platform 11114 on the long axis D3 may be larger than the dimension of the first annular bearing platform 11114 on the short axis D4, for example, the first annular bearing platform 11114 is arranged in a racetrack. Wherein, the plurality of upright posts 11115 may be symmetrically disposed on both sides of the major axis D3 and the minor axis D4 to increase the reliability of the connection between the deck 1112 and the deck 1111; similarly, a plurality of snaps may be symmetrically disposed on both sides of major axis D3 and minor axis D4 to increase the reliability of the face component 114 and the cartridge case 1111.

As an example, referring to fig. 7 and 8, the plurality of posts 11115 and the plurality of fastening portions may be offset, which is beneficial to avoid demolding interference during a molding process such as injection molding. Accordingly, one communication hole 11112 may be provided at an interval between any adjacent two of the catching portions in the circumferential direction of the first cylindrical sidewall 11113, so that the size of the communication hole 11112 in the circumferential direction of the first cylindrical sidewall 11113 is as large as possible.

As an example, as seen in the vibration direction D1 with reference to fig. 7 and 8, the communication holes 11112 may be divided into four groups, two groups of communication holes 11112 may be disposed opposite to each other on the long axis D3, and the remaining two groups of communication holes 11112 may be disposed opposite to each other on the short axis D4. In this way, standing waves in the first cavity are advantageously reduced. Although each group of communication holes 11112 in fig. 7 and 8 has only one communication hole 11112, a person skilled in the art may set a plurality of communication holes 11112 in at least one group of communication holes 11112 according to actual needs, which is not described herein.

As an example, in conjunction with fig. 2, 3, and 11, the deck module 11 may include a microphone assembly 116, with the microphone assembly 116 disposed within the housing assembly 111. Wherein the microphone assembly 116 may pick up at least one of ambient sound, user speech, etc. Further, the microphone assembly 116 may include a first microphone 1161, where the first microphone 1161 falls on the transducer 112 when orthographic projected onto the transducer 112 along the vibration direction D1, for example, the first microphone 1161 is fixed on the bottom of the housing assembly 111 and is spaced apart from the transducer 112 along the vibration direction D1. The movement module 11 may further include a limiting member 117 disposed in the housing assembly 111, where the limiting member 117 is configured to stop the transduction device 112 when a movement amplitude of the transduction device 112 in the vibration direction D1 exceeds a preset amplitude threshold, so that a predetermined distance is maintained between the transduction device 112 and the first microphone 1161, which is beneficial to avoiding the first microphone 1161 from being damaged by the transduction device 112, especially under extreme conditions such as dropping, collision, etc. of the movement module 11.

Further, the amplitude threshold may be greater than the maximum amplitude of the transducer 112 when the deck 11 is operating normally. In other words, when the user daily uses the electronic device 10, even if the volume of the electronic device 10 is maximized, the transducer 112 will not collide with the structure such as the stopper 117, so as to avoid noise of the movement module 11.

In some embodiments, the stop 117 may be provided in a ring or block. The center of the limiting member 117 and the center of the transducer 112 may be aligned in the vibration direction D1, so that the distribution of the force when the limiting member 117 stops the transducer 112 is more uniform. In some embodiments of the present application, the limiting member 117 may be disposed adjacent to the first microphone 1161, so as to better avoid the first microphone 1161 from being damaged by the transducer device 112 through the limiting member 117, especially under extreme working conditions such as dropping and collision of the movement module 11. The positioning of the limiting member 117 adjacent to the first microphone 1161 means that, in a direction of a line connecting a center of the limiting member 117 and a center of the first microphone 1161, a distance between the limiting member 117 and the first microphone 1161 may be at least less than half a size of the transducer 112 in the direction of the line. For example, placement of the stop 117 adjacent the first microphone 1161 means that in a direction of a line connecting a center of the stop 117 and a center of the first microphone 1161, a distance between the stop 117 and the first microphone 1161 may be at least less than 1/2, 1/3, 1/4, 1/5, etc. of a dimension of the transducer 112 in the direction of the line. In some embodiments, the material of the limiting member 117 may be polycarbonate or at least one of glass fiber and carbon fiber mixed therein. Alternatively, the material of the limiting member 117 may be a structure with a certain elasticity, such as silica gel, rubber, or sponge, and when the transduction device 112 collides with the limiting member 117, the limiting member 117 can provide a certain buffer, so as to avoid or reduce the damage possibly caused by the transduction device 112. It should be understood that, in this application, the limiting member 117 may be any other material, and this application is not limited in particular. The limiting member 117 may be fixed to the bottom of the housing assembly 111 or to the transducer 112. Further, when the stopper 117 is fixed on the bottom of the housing assembly 111, the stopper 117 and the housing assembly 111 may be integrally formed as a structural member.

As an example, in connection with fig. 2, the stopper 117 and the first microphone 1161 may be configured to remain relatively fixed, for example, both are fixed to the bottom of the deck casing 1111, respectively, and for example, the stopper 117 is a part of the structure of the deck casing 1111 and the first microphone 1161 is fixed to the bottom of the deck casing 1111. The front projection of the transducer 112 along the vibration direction D1 covers the first microphone 1161 and the limiting member 117, so that the limiting member 117 stops the transducer 112. Further, in the vibration direction D1, the side of the stopper 117 facing the transducer 112 is higher than the side of the first microphone 1161 facing the transducer 112 to avoid the first microphone 1161 from being bumped by the transducer 112.

In some other embodiments, the stop 117 and the first microphone 1161 may be both fixed to the bottom of the housing assembly 111, the stop 117 is fixed to the transducer 112, and the first microphone 1161 is fixed to the bottom of the housing assembly 111. In the vibration direction D1, a distance between a side of the stopper 117 facing the bottom of the housing assembly 111 and the bottom of the housing assembly 111 is smaller than a distance between a side of the first microphone 1161 facing the transducer 112 and the transducer 112, so as to avoid the first microphone 1161 from being bumped by the transducer 112.

As an example, in conjunction with fig. 2 and 3, the microphone assembly 116 may include a second microphone 1162, and a flexible circuit board 1163 connecting the first microphone 1161 and the second microphone 1162, the second microphone 1162 being fixed on a side wall of the deck housing 1111. The cartridge housing 1111 may be provided with a wiring groove in which the flexible circuit board 1163 is fixed. Thus, the aforementioned wiring groove can play a role in positioning during the assembly of the flexible circuit board 1163 with the deck casing 1111; and when the two are connected through glue, the wiring groove can also play a role in preventing glue overflow. At this time, since the flexible circuit board 1163 is fixed in the aforementioned wiring groove, the area where the flexible circuit board 1163 is located can be simply regarded as the aforementioned wiring groove. Further, the limiting member 117 and the wiring groove are staggered from each other to avoid interference during the processing. Accordingly, a sound pickup hole may be provided on the deck casing 1111 to be engaged with the first microphone 1161 and the second microphone 1162, respectively.

As an example, referring to fig. 11, the flexible circuit board 1163 may include a first flexible circuit part 11631 and a second flexible circuit part 11632 integrally connected, the first microphone 1161 may be attached to an end of the first flexible circuit part 11631 remote from the second flexible circuit part 11632 by means of a surface mount technology (Surface Mounted Technology, SMT), and the second microphone 1162 may be attached to an end of the second flexible circuit part 11632 remote from the first flexible circuit part 11631 by means of a surface mount technology, thereby constituting the microphone assembly 116 to facilitate assembly. The angle between the front projection of the first flexible circuit portion 11631 on a reference plane (e.g., paper) perpendicular to the vibration direction D1 and the front projection of the second flexible circuit portion 11632 on the aforementioned reference plane may be greater than 90 ° and less than 180 °, that is, the flexible circuit board 1163 is bent to an obtuse angle, so that the first microphone 1161 and the second microphone 1162 are diagonally disposed in the housing assembly 111, thereby increasing the interval between the two microphones and improving the pick-up effect of the microphone assembly 116.

As an example, referring to fig. 2 and 3, the cartridge case 1111 may include a second cylindrical sidewall 11116 and a bottom wall 11117 connected to one end of the second cylindrical sidewall 11116, and the open end of the second cylindrical sidewall 11116 may be provided with a second annular bearing platform 11118, and the second cylindrical sidewall 11116 partially protrudes into the first cylindrical sidewall 11113, such that the first cylindrical sidewall 11113 is supported on the second annular bearing platform 11118. Wherein, the overlapping portion of the first cylindrical sidewall 11113 and the second cylindrical sidewall 11116 may be provided with a fastening structure, so that the two are fastened and fixed; the second annular bearing platform 11118 may be provided with a glue containing groove, so that the first cylindrical side wall 11113 and the second annular bearing platform 11118 are glued and fixed, which is beneficial to increasing the reliability of connection between the first cylindrical side wall 11113 and the second cylindrical side wall 11116. Accordingly, the first microphone 1161 may be fixed on the bottom wall 11117, the second microphone 1162 may be fixed on the second cylindrical sidewall 11116, and the wiring groove may be partially formed in the bottom wall 11117 and another portion formed in the second cylindrical sidewall 11116; the stop 117 may be fixed to the bottom wall 11117 or may be a structure that is part of the bottom wall 11117.

Based on the above-described related description, the deck casing 1111 may include a first casing and a second casing connected to the first casing. The first housing may include a first cylindrical sidewall 11113 and a first annular bearing platform 11114 connected to an inner wall surface of the first cylindrical sidewall 11113, and the second housing may include a second cylindrical sidewall 11116 and a bottom wall 11117 connected to one end of the second cylindrical sidewall 11116, where the second cylindrical sidewall 11116 is connected to the first cylindrical sidewall 11113, so that the second housing seals one end of the first cylindrical sidewall 11113, and the other end of the first cylindrical sidewall 11113 is open. Accordingly, the microphone assembly 116 can be fixed in the second housing, and the depth of the second housing is relatively shallow, which is beneficial to reducing the assembling difficulty of the microphone assembly 116. Further, the housing assembly 111 may include a flexible coating 1114 wrapped around the outside of the second housing, e.g., the flexible coating 1114 wrapped around the outside of the second cylindrical sidewall 11116 and the bottom wall 11117, and the outer surface of the flexible coating 1114 may be flush with the outer surface of the first cylindrical sidewall 11113 to fill the step between the first cylindrical sidewall 11113 and the second cylindrical sidewall 11116. Wherein the hardness of the flexible cover 1114 may be less than the hardness of the cartridge housing 1111.

As an example, in connection with fig. 12, 15, and 21, the electronic device 10 may include a housing assembly 121, and a circuit board 1221 and an antenna mount 123 disposed within the housing assembly 121, and the antenna mount 123 may be supported at one side of the circuit board 1221. Wherein, the housing assembly 121 may include a housing 1211 and a lamp cover 1222 disposed in a sidewall of the housing 1211, the antenna support 123 and the circuit board 1221 are at least partially received in the housing 1211, and the antenna support 123 may be located at a side of the circuit board 1221 facing the lamp cover 1222. Further, the circuit board 1221 may be provided with an indicator light 1223 on a side facing the lampshade 1222, the antenna support 123 may include an antenna supporting portion 1231 and a light guiding portion 1232 connected to the antenna supporting portion 1231, the light guiding portion 1232 and the lampshade 1222 are light transmitting members, the light guiding portion 1232 is configured to guide light emitted by the indicator light 1223 to exit to the outside of the electronic device 10, for example, light emitted by the indicator light 1223 propagates to the lampshade 1222 through the light guiding portion 1232 and exits to the outside of the electronic device 10. In this way, even if the space between the indicator light 1223 and the lamp shade 1222 is larger due to the antenna support 123, the light loss of the indicator light 1223 is reduced under the guidance of the light guiding portion 1232, so that the indicator light 1223 does not need to increase the light emitting power, thereby reducing the power consumption of the indicator light 1223 and prolonging the service life of the indicator light 1223.

In some embodiments, the outer surface of the light guiding portion 1232 may be coated with a reflective coating or form a patterned surface, and the light is refracted inside the light guiding portion 1232, so as to reduce light leakage exiting from the side surface of the light guiding portion 1232 and improve the light utilization rate. The light-guiding portion 1232 needs to be exposed toward the light-incident surface of the indicator light 1223 and the light-emitting surface of the lamp shade 1222, for example, the light-reflecting coating is not coated or the light-emitting surface is not formed with a pattern, so as to allow the light-guiding portion 1232 to pass through.

As an example, in connection with fig. 12, 15 and 21, the center of the orthographic projection of the lamp shade 1222 on the circuit board 1221 may be misaligned with the center of the indicator light 1223, i.e., the lamp shade 1222 is offset with respect to the indicator light 1223, to make the setting of the lamp shade 1222 more flexible. In the normal direction of the circuit board 1221 (for example, the direction indicated by an arrow D5 in fig. 12 and 15), the cross-sectional area of the end of the light guiding portion 1232 near the circuit board 1221 may be larger than the cross-sectional area of the other end of the light guiding portion 1232 near the lamp shade 1222, so as to change the light path of the light emitted by the indicator light 1223 and make the light emitted by the indicator light 1223 reaching the lamp shade 1222 more concentrated. Of course, the center of the orthographic projection of the lamp shade 1222 on the circuit board 1221 may also coincide with the center of the indicator light 1223.

As an example, in connection with fig. 12, an end surface of the light guide portion 1232 facing the indication lamp 1223 may be provided as a curved surface recessed toward the inside of the light guide portion 1232, similar to a concave structure, to better collect light emitted from the indication lamp 1223.

As an example, referring to fig. 12 and 21, the antenna mount 123 may include a connection rib 1233 connecting the light guide portion 1232 and the antenna support portion 1231, that is, the light guide portion 1232 is connected to the antenna support portion 1231 through the connection rib 1233. Further, a ratio between the thickness of the connection rib 1233 in the normal direction D5 and the height of the light guiding portion 1232 in the normal direction D5 may be between 0.3 and 0.5. Wherein, if the aforementioned ratio is too small, it is liable to cause insufficient connection strength between the light guide part 1232 and the antenna support part 1231; if the above ratio is too large, the light emitted from the indicator lamp 1223 is easily leaked to the antenna supporting part 1231 via the connection rib 1233 too much.

In some embodiments, the antenna support part 1231, the light guide part 1232, and the connection rib 1233 may be integrally formed structures of the same material, for example, integrally formed through an injection molding process.

In some embodiments, the antenna support 1231 and the light guide 1232 may be integrally formed structures of different materials, such as by a two-shot molding process. The connection rib 1233 may be formed as a part of the antenna support part 1231 or the light guide part 1232.

As an example, in connection with fig. 12, 17 and 21, the side of the antenna support 1231 facing away from the circuit board 1221 may be provided with an antenna pattern 1224, and the antenna pattern 1224 may abut on the circuit board 1221 through a metal elastic member 1225 to make electrical contact. Wherein, the antenna pattern 1224 may be located at a side of the antenna supporting part 1231 facing the lamp shade 1222 to increase a space between the antenna pattern 1224 and the circuit board 1221, i.e., increase an antenna clearance area, thereby increasing interference immunity of the antenna pattern 1224. Further, the antenna pattern 1224 may be formed on the antenna supporting part 1231 by a Laser-Direct-structuring (LDS) technology, or may be a flexible circuit board adhered to the antenna supporting part 1231. The metal elastic member 1225 may be a pogo-PIN or a metal spring, etc., which is not limited herein. Further, a metal elastic member 1225 may be fixed to the circuit board 1221.

It should be noted that: referring to fig. 1 and 12, the lamp cover 1222 may be located at an outer side of the circuit board 1221 in a wearing state, so that light emitted from the indication lamp 1223 and guided through the light guiding portion 1232 and the lamp cover 1222 is not blocked. Similarly, in the worn state, the antenna pattern 1224 may be located further to the outside than the circuit board 1221, e.g., the antenna pattern 1224 is located between the circuit board 1221 and the lamp cover 1222 to further increase the interference immunity of the antenna pattern 1224. Further, in other embodiments, the electronic device 10 may not include the antenna support 123, for example, the antenna pattern 1224 is disposed on the housing assembly 121 or on the circuit board 1221, and for example, the lamp shade 1222 extends further into the housing assembly 121 to shorten the distance between the lamp shade and the indicator light 1223.

As an example, referring to fig. 21, the antenna support 123 may include a positioning post 1234 connected to the antenna supporting portion 1231 and a fastening portion 1235, where the positioning post 1234 plays a role in positioning during the assembly of the antenna support 123 and the circuit board 1221, and the fastening portion 1235 makes the antenna support 123 and the circuit board 1221 fastened. The number of the positioning columns 1234 and the fastening portions 1235 may be plural, and after the positioning columns 1234 extend into the positioning holes of the circuit board 1221, the fastening portions 1235 may be fastened to different sides of the circuit board 1221, so that the connection between the antenna support 123 and the circuit board 1221 is more reliable. Notably, are: due to the view angle, fig. 21 only illustrates one positioning post 1234 and the fastening portion 1235, respectively. Accordingly, when the antenna support 123 is snapped onto the circuit board 1221, the metallic spring 1225 is simultaneously in electrical contact with the antenna pattern 1224.

As an example, in connection with fig. 12, 15 and 17, the housing assembly 121 may include an end cap 12121 coupled to the housing body 1211, and the antenna mount 123 and the circuit board 1221 may be inserted together in an insertion direction (e.g., the direction indicated by arrow D6 in fig. 15 and 17) and at least partially into the housing body 1211 via an open end of the housing body 1211, the end cap 12121 being further coupled to the open end of the housing body 1211 such that the circuit board 1221 and the antenna mount 123 and structural components thereon are positioned within the housing assembly 121. In this way, since the lamp shade 1222 and the antenna support 123 are two separate structural components, they and their related structural components can be assembled together according to a certain assembly sequence, so that the electronic device 10 will not have the technical problem of difficult assembly due to structural interference during the assembly process. Accordingly, the light guide 1232 is located between the indication lamp 1223 and the lamp housing 1222 after the antenna mount 123 and the circuit board 1221 are assembled in place.

Similarly, the end cap 12121 may extend partially into the cartridge body 1211 and may rest on a third annular deck inside the open end of the cartridge body 1211. Wherein, the overlapping part of the end cover 12121 and the bin 1211 may be provided with a fastening structure, so that the end cover 12121 and the bin 1211 are fastened and fixed; the third annular bearing platform can be provided with a glue containing groove, so that the end cover 12121 is glued and fixed with the third annular bearing platform, which is beneficial to increasing the reliability of the connection between the end cover 12121 and the bin 1211. Further, the housing assembly 121 can include a flexible coating 12122 that wraps around the outside of the end cap 12121, and an outer surface of the flexible coating 12122 can be flush with an outer surface of the cartridge body 1211 to fill in the step between the end cap 12121 and the cartridge body 1211. Wherein the hardness of the flexible cover 12122 may be less than the hardness of the end cap 12121. Notably, are: the flexible cover 12122 and the flexible cover 1114 may be injection molded as a unitary structure.

As an example, referring to fig. 12 and 18, a stepped hole 1213 may be provided on a sidewall of the bin body 1211, and the lamp shade 1222 is assembled in the stepped hole 1213. Wherein, the lamp shade 1222 may include a first light-transmitting portion 12221 and a second light-transmitting portion 12222 integrally connected, a radial dimension of the first light-transmitting portion 12221 being smaller than a radial dimension of the second light-transmitting portion 12222; the stepped hole 1213 may include a first hole section and a second hole section communicating with each other, the first hole section having a radial dimension smaller than a radial dimension of the second hole section, the first hole section being closer to the circuit board than the second hole section in the normal direction D5; the first light transmitting portion 12221 is embedded in the first hole section, and the second light transmitting portion 12222 is embedded in the second hole section and supported on the stepped surface of the stepped hole 1213. In other words, the lamp shade 1222 can be assembled in the stepped hole 1213 along the assembling direction from outside to inside, which is beneficial to preventing the lamp shade 1222 from being immersed into the bin 1211 under the action of external force, so as to maintain the relative positional relationship between the lamp shade 1222 and the bin 1211.

As an example, referring to fig. 12, 18 and 21, the electronic device 10 may include a sliding key assembly 124 connected to the housing assembly 121, where the sliding key assembly 124 can toggle a toggle switch 1226 disposed on the circuit board 1221 along a sliding direction (e.g., a direction indicated by an arrow D7 in fig. 12) under an external force, so as to extend a control function of the electronic device 10, for example, to implement on/off of the electronic device 10. The sliding key assembly 124 may extend from the outside of the housing assembly 121 into the inside of the housing assembly 121 via the sliding slot 1214 on the housing assembly 121, and further connect with the toggle switch 1226 via the escape slot 1236 on the antenna bracket 123, so that the user can toggle the toggle switch 1226 through the sliding key assembly 124. Further, a portion of the sliding key assembly 124 may be limited between the antenna support 123 and the housing assembly 121, so that the sliding key assembly 124 is prevented from invading into the housing assembly 121 under the action of external force, and the sliding key assembly 124 is prevented from being separated from the housing assembly 121.

As an example, in conjunction with fig. 12 and 18-21, the sliding key assembly 124 may include a cradle 1241 and a sliding key 1242, the sliding key 1242 may be connected to the toggle switch 1226 through the cradle 1241 and configured to receive an external force applied by a user to toggle the toggle switch 1226. The adaptor bracket 1241 is disposed in the housing assembly 121, and extends from one side of the antenna bracket 123 to the other side of the antenna bracket 123 through the avoidance slot 1236, and is further connected to the toggle switch 1226; the sliding key 1242 extends from the outside of the housing assembly 121 into the inside of the housing assembly 121 via the sliding groove 1214, and is connected to the adaptor holder 1241. In short, the sliding key 1242 is fittably connected to the adaptor holder 1241. In this way, since the adaptor holder 1241 and the sliding key 1242 are two separate structural components, they and their related structural components can be assembled together according to a certain assembly sequence, so that the electronic device 10 will not have a technical problem that it is difficult to assemble due to structural interference during the assembly process. Accordingly, a portion of the adapter 1241 may be captured between the antenna mount 123 and the housing assembly 121 to prevent the sliding key assembly 124 from being separated from the housing assembly 121 after the sliding key assembly 124 is assembled with structural components such as the housing assembly 121. Of course, in other embodiments, to prevent the sliding key assembly 124 from being separated from the housing assembly 121, for example, a portion of the sliding key 1242 is limited to the inner side of the housing assembly 121 facing the circuit board 1221, and for example, an additional limiting member such as a snap ring or a latch independent of the sliding key 1242 is provided, and the limiting member is limited to the inner side of the housing assembly 121 facing the circuit board 1221 after being assembled with the sliding key 1242; in order for the sliding key assembly 124 to toggle the toggle switch 1226, the sliding key assembly 124 may also not include the adaptor holder 1241, such as a second connector 12422 described later, connected to the toggle switch 1226.

As an example, referring to fig. 12 and 18 to 21, the adaptor holder 1241 may include an annular main body part 12411 and a first plug part 12412 connected to the annular main body part 12411, the annular main body part 12411 being located at a side of the antenna support 123 facing away from the circuit board 1221, the first plug part 12412 being connected to the toggle switch 1226 through the escape groove 1236; the sliding key 1242 may include an operation portion 12421, a second plug portion 12422 connected to the operation portion 12421, and a locking portion 12423 connected to the second plug portion 12422, where the operation portion 12421 is located outside the housing assembly 121 so as to receive an external force applied by a user, the second plug portion 12422 passes through the sliding slot 1214 and extends into the slot 12413 of the annular body portion 12411, and the locking portion 12423 is locked with a side of the annular body portion 12411 facing the circuit board 1221, that is, the locking portion 12423 is located on a side of the annular body portion 12411 facing the circuit board 1221, so that the sliding key 1242 is locked with the adapter holder 1241. Of course, in other embodiments, in order to achieve the locking and fixing of the sliding key 1242 and the adapting frame 1241, the sliding key 1242 may not include the locking portion 12423, for example, an additional limiting element such as a snap ring or a latch independent of the sliding key 1242 may be provided, and the limiting element is located on a side of the adapting frame 1241 facing the circuit board 1221 after being assembled with the sliding key 1242.

In some embodiments, the length of the annular body portion 12411 in the sliding direction D7 may be greater than the length of the escape groove 1236 in the sliding direction D7, such that the annular body portion 12411 can be captured between the antenna mount 123 and the housing assembly 121.

In some embodiments, the width of the annular body part 12411 in the direction perpendicular to the sliding direction D7 and the plugging direction may be greater than the width of the escape groove 1236 in the direction perpendicular to the sliding direction D7 and the foregoing plugging direction, so that the annular body part 12411 can be restrained between the antenna mount 123 and the housing assembly 121. The plugging direction may be defined as an assembling direction of the sliding key 1242 to be plugged with the adaptor 1241, for example, the plugging direction is parallel to an extending direction of the second plugging portion 12422.

Because the length of the annular main body part 12411 may be greater than the length of the avoidance groove 1236, the width of the annular main body part 12411 may be greater than the width of the avoidance groove 1236, so that the annular main body part 12411 may be supported on the antenna support 123, especially in the process of connecting the sliding key 1242 with the adaptor holder 1241 along the above-mentioned assembly direction, so as to simplify the assembly process. Wherein, referring to fig. 12 and 21, a side of the antenna support 123 facing away from the circuit board 1221 may be provided with a limiting groove 1237, the avoiding groove 1236 is disposed at the bottom of the limiting groove 1237, and the annular main body part 12411 may be at least partially located in the limiting groove 1237, so as to be beneficial to reducing the size of the housing assembly 121 in the normal direction D5.

As an example, referring to fig. 12, 19 and 20, the second plugging portion 12422 and the engaging portion 12423 may be disposed with two groups at intervals along the sliding direction D7, and the two engaging portions 12423 are at least partially located at two opposite sides of the two second plugging portions 12422, so that the sliding key 1242 is clamped and fixed with the adapting frame 1241, and the sliding key 1242 and the adapting frame 1241 are prevented from moving relatively. Accordingly, the dimension of the slot 12413 in the sliding direction D7 may be larger than the dimension of the slot 12413 in the direction perpendicular to the sliding direction D7 and the above-described plugging direction. The side of the slot 12413 facing away from the circuit board 1221 may be provided with a first guiding surface 12414, and the engagement portion 12423 may be provided with a second guiding surface 12424. In this way, during the process of extending the sliding key 1242 into the adaptor holder 1241, the second guiding surface 12424 and the first guiding surface 12414 cooperate with each other to bring the two sets of the second connector portion 12422 and the engaging portion 12423 close to each other, so that the two engaging portions 12423 pass through the slot 12413; accordingly, after the two engaging portions 12423 pass through the slot 12413, the relative positions between the two sets of second inserting portions 12422 and the engaging portions 12423 can be restored to the state before the sliding key 1242 is assembled with the adapting frame 1241, so that the two engaging portions 12423 are stopped by the annular main body portion 12411 in the opposite direction of the sliding key 1242 extending into the adapting frame 1241, thereby realizing the engagement and fixation of the sliding key 1242 and the adapting frame 1241. Of course, in some embodiments, only one set of the second connector part 12422 and the engaging part 12423 may be provided, and the relative fixing between the sliding key 1242 and the adapter holder 1241 may be maintained by a snap ring.

As an example, in connection with fig. 12 and 17, the extending direction of the switch handle of the toggle switch 1226 may be perpendicular to the normal direction D5, which is advantageous for reducing the size of the housing assembly 121 in the normal direction D5. Correspondingly, referring to fig. 20, the number of the first plugging portions 12412 may be two, the two first plugging portions 12412 are disposed at intervals in the sliding direction D7, and the switch handle of the toggle switch 1226 is clamped between the two first plugging portions 12412, so that the switch holder 1241 and the switch handle of the toggle switch 1226 are clamped and fixed, so that the sliding key 1242 is convenient to toggle the toggle switch 1226 through the switch holder 1241. Of course, in some embodiments, the number of the first plugging portions 12412 may be one, and the switch handle of the toggle switch 1226 may be provided with a hole, so as to allow the first plugging portion 12412 to partially extend into the hole, and also enable the first plugging portion 12412 to be connected with the switch handle of the toggle switch 1226.

As an example, referring to fig. 12 and 13, the operation portion 12421 may be provided with a sealing groove 12425 surrounding the sliding groove 1214 toward the inside of the circuit board 1221, and the sliding key assembly 124 may include a sealing ring 1243 provided in the sealing groove 12425 to seal the sliding groove 1214. In addition, since the seal ring 1243 has a certain compression amount, the seal ring 1243 can provide a certain damping in the process of operating the sliding key 1242 by a user, and has better sliding hand feeling. The seal ring 1243 shown in fig. 12 and 13 is in a form before compression, and has a certain deformation amount after compression, so as to be elastically supported between the sliding key 1242 and the housing assembly 121, and achieve a good sealing effect on the sliding groove 1214. Of course, in other embodiments, seal groove 12425 may be provided on housing assembly 121.

Since the seal ring 1243 is elastically supported between the operation portion 12421 and the housing assembly 121, the adaptor bracket 1241 can be pressed against the housing assembly 121, so as to prevent the sliding key assembly 124 from shaking relative to the housing assembly 121. In conjunction with fig. 20, the adaptor bracket 1241 may include a sliding rib 12415 disposed on a side of the annular body portion 12411 facing away from the circuit board 1221, where the adaptor bracket 1241 is slidably supported on the housing assembly 121 by the sliding rib 12415, so as to reduce a contact area between the adaptor bracket 1241 and the housing assembly 121, thereby reducing a friction resistance when the sliding key assembly 124 slides relative to the housing assembly 121.

In some embodiments, the number of the sliding ribs 12415 may be plural, for example, two as shown in fig. 20, the plurality of sliding ribs 12415 may be stripe-shaped, and each sliding rib 12415 may extend along the sliding direction D7 on both sides of the slot 12413 in the direction perpendicular to the sliding direction D7 and the above-mentioned plugging direction.

In some embodiments, the sliding rib 12415 may be provided in a ring shape and surround the slot 12413.

As an example, referring to fig. 12, 13 and 18, the housing assembly 121 may be provided with a recess 1215 on the outer side thereof, the sliding groove 1214 is provided at the bottom of the recess 1215, and the operation part 12421 may be at least partially located in the recess 1215, which is advantageous in reducing the size of the electronic device 10 in the normal direction D5.

In some embodiments, after sliding the sliding key assembly 124 in the sliding direction D7 relative to the housing assembly 121 to the toggle switch 1226 in the open state or the closed state, the operating portion 12421 can be stopped by a sidewall of the recessed area 1215 to avoid overdriving the sliding key assembly 124.

In some embodiments, after the sliding key assembly 124 slides relative to the housing assembly 121 in the sliding direction D7 to the toggle switch 1226 in the open state or the closed state, the annular body 12411 can be stopped by a sidewall of the limiting groove 1237 to avoid overdriving the sliding key assembly 124.

As an example, in connection with fig. 12 and 13, the bottom of the recessed area 1215 is provided with an annular groove 1216 at a position connected with the side wall of the recessed area 1215 to eliminate the R angle at the corner between the bottom and the side wall of the recessed area 1215, particularly when the housing assembly 121 is manufactured by an injection molding process. The electronic device 10 may include a spacer 1244 attached to the bottom of the recess 1215, where the spacer 1244 covers the annular groove 1216, and an edge of the spacer 1244 is suspended above the annular groove 1216, so as to allow the spacer 1244 to be attached flatly, and avoid the edge of the spacer 1244 from tilting. Accordingly, the sliding key assembly 124 may be supported on a spacer 1244. In addition, since the edges of the pads 1244 do not lift, the sliding key assembly 124 can slide into place in the sliding direction D7. For example: after the sliding key assembly 124 is slid in the sliding direction D7 relative to the housing assembly 121 to the toggle switch 1226 in the open state or the closed state, the edge of the operating portion 12421 is located above the annular groove 1216.

Further, the outer side wall of annular groove 1216 away from runner 1214 may be flush with the side wall of recessed region 1215.

In some embodiments, the pad 1244 may be provided with text, color, symbol, or other indication information for indicating the ON state or the OFF state of the toggle switch 1226, for example, the text "ON" and "OFF" indicate the ON state and the OFF state, respectively, and for example, green and red indicate the ON state or the OFF state, respectively. Wherein the aforementioned indication information may be provided at the inner side of the pad 1244 toward the bottom of the recess 1215 to prevent the aforementioned indication information from being worn out. Of course, the foregoing indication information may also be provided on the bottom of the recessed area 1215.

In some embodiments, the spacer 1244 may be used to adjust the damping of the seal ring 1243 during sliding of the sliding key assembly 124 relative to the housing assembly 121 in the sliding direction D7.

As an example, referring to fig. 12 and 18, the stepped hole 1213, the sliding groove 1214, the recess 1215, and the like may be located on the same side wall of the housing 1211 such that the sliding key assembly 124 and the lamp housing 1222 are located on the same side of the circuit board 1221, so that the user operates the sliding key assembly 124 in a wearing state.

As an example, in connection with fig. 12 and 14, the electronic device 10 includes a third microphone 1251 disposed within the housing assembly 121, the third microphone 1251 being capable of picking up at least one of ambient sound, user speech, and the like. Wherein the housing assembly 121 may be provided with a sound pickup channel 1217, and the third microphone 1251 is used to pick up sound incoming via the sound pickup channel 1217. Further, the pickup channel 1217 may include a first channel segment 12171 and a second channel segment 12172 in communication with each other. In some embodiments of the present application, the first and second passage segments 12171, 12172 communicate and communicate the interior of the housing assembly 121 with the outside world via the first and second passage segments 12171, 12172. Wherein the first channel segment 12171 is closer to the third microphone 1251 than the second channel segment 12172, the first central axis of the first channel segment 12171 and the second central axis of the second channel segment 12172 may not be coincident. As such, the first and second channel segments 12171, 12172 are offset from one another, which facilitates avoiding direct impact of external droplets or the like on the third microphone 1251, thereby extending the useful life of the third microphone 1251.

In other embodiments of the present application, pickup channel 1217 may include three or more channel segments that communicate with each other and with the interior of housing assembly 121 and the outside.

Further, the electronic device 10 may include a protective mesh 1252 disposed within the housing assembly 121, the protective mesh 1252 covering the first passage segment 12171. In this way, direct impact of external droplets and the like on the third microphone 1251 is advantageously further avoided, thereby prolonging the service life of the third microphone 1251. Wherein, the first central axis and the second central axis may be perpendicular to the protection net 1252, respectively.

As an example, in conjunction with fig. 12 and 14, the orthographic projection of the first channel segment 12171 on the protective screen 1252 and the orthographic projection of the second channel segment 12172 on the protective screen 1252 may partially overlap such that the first central axis of the first channel segment 12171 does not coincide with the second central axis of the second channel segment 12172.

Further, the cross-sectional area of the second passage segment 12172 in a reference plane perpendicular to the first central axis may be greater than the cross-sectional area of the first passage segment 12171 in a reference plane perpendicular to the second central axis, e.g., the first and second passage segments 12171 and 12172 are each cylindrical bores and the bore diameter of the former is smaller than the bore diameter of the latter. As such, the pickup channel 1217 is generally horn-shaped such that more sound enters the pickup channel 1217 and is better focused before entering the third microphone 1251.

It should be noted that: in the process of manufacturing the housing assembly 121 by such as injection molding, the first and second passage segments 12171 and 12172, respectively, may be formed on the housing assembly 121 by two cores, with the demolding directions of the two cores being opposite to each other so as to obtain the first and second passage segments 12171 and 12172 having different cross-sectional areas.

In some embodiments, the overlapping area between the orthographic projection of the first passage segment 12171 on the protective screen 1252 and the orthographic projection of the second passage segment on the protective screen 1252 has an overlapping area, the orthographic projection of the first passage segment 12171 on the protective screen 1252 has a projected area, and the ratio between the aforementioned overlapping area and the aforementioned projected area may be between 0.4 and 0.6. Wherein, if the aforementioned ratio is too small, it is liable to cause the communication area between the first passage segment 12171 and the second passage segment 12172 to be too small to facilitate sound entering the third microphone 1251 via the sound pickup passage 1217; if the aforementioned ratio is too large, it is liable to cause an increased risk of the third microphone 1251 being directly impacted by the external liquid droplets or the like.

In some embodiments, the first central axis and the second central axis may be disposed in parallel, so that the wall thickness of the housing assembly 121 is more uniform, and local excessive thinning is avoided. Wherein, in conjunction with fig. 14, the first channel segment 12171 and the second channel segment 12172 partially overlap on the first axis, the ratio of the size of the overlapping portion of the first channel segment 12171 and the second channel segment 12172 (e.g., |h1-h2|) to the smaller of the depth of the first channel segment 12171 (e.g., h1 in fig. 14) and the depth of the second channel segment 12172 (e.g., h2 in fig. 14) may be between 0.5 and 0.8. Wherein, if the aforementioned ratio is too small, it is liable to cause the communication area between the first passage segment 12171 and the second passage segment 12172 to be too small to facilitate sound entering the third microphone 1251 via the sound pickup passage 1217; if the aforementioned ratio is too large, it is liable to cause local excessive thinning of the housing assembly 121. It will be appreciated that in some other embodiments, the first central axis and the second central axis may be disposed at an angle, so as to adjust the length of the sound pickup channel 1217 when the wall thickness of the housing assembly 121 is constant.

As an example, referring to fig. 12, 15 and 17, the housing assembly 121 has a first direction, a second direction and a third direction orthogonal to each other, the housing assembly 121 may include a bin 1211 and an end cap 12121 that are fastened to each other in the aforementioned first direction, and the size of the housing assembly 121 in the aforementioned second direction may be greater than the size of the housing assembly 121 in the aforementioned third direction. Wherein the aforementioned first direction, second direction, and third direction may be parallel to the insertion direction D6, sliding direction D7, and normal direction D5, respectively, based on the above-described related description. In other words, the housing assembly 121 is provided in a flat structure, which is advantageous in reducing the size of the housing assembly 121 in the normal direction D5.

As an example, in connection with fig. 17, the cartridge body 1211 has a first inner wall 12111 and a second inner wall 12112 spaced apart from each other in the above-described second direction, and the size of the first inner wall 12111 in the above-described first direction may be smaller than the size of the second inner wall 12112 in the above-described first direction, that is, the depth of the cartridge body 1211 in the above-described first direction is not equal everywhere but has a certain difference. Wherein the protection net 1252 may be fixed on the first inner wall 12111, and the third microphone 1251 is fixed on the protection net 1252. In this way, the third microphone 1251, the protection net 1252 and other related structures are arranged at the position with shallower depth in the bin 1211, so that the assembly difficulty of the electronic device 10 is lower. Accordingly, the pickup channel 1217 may be provided on a side wall of the cartridge body 1211.

Further, the first inner wall 12111 may be formed with an invagination area 12113 thereon, and the sound pickup passage 1217 communicates with the bottom of the invagination area 12113. Wherein, the protection net 1252 may be fixed to the bottom of the subsidence area 12113 by a glue such as a double sided tape or a glue, and the third microphone 1251 may be at least partially positioned in the subsidence area 12113 and may be fixed to the protection net 1252 by a glue such as a double sided tape or a glue, so as to increase the anti-falling capability of the third microphone 1251. Similarly, the third microphone 1251 may be attached to the flexible circuit board 1253 by means of surface mount technology, and further connected to the circuit board 1221.

As an example, the first inner wall 12111 may be closer to the middle position of the support assembly 12 than the second inner wall 12112, that is, further away from the deck module 11, and in the worn state, the sound pickup channel 1217 may be directed toward the rear of the brain, which is advantageous for increasing the anti-interference capability of the third microphone 1251.

It should be noted that: the related modification of the sound pickup passage 1217 may also be applied to sound pickup holes provided in the housing assembly 111, which are respectively engaged with the first microphone 1161 and the second microphone 1162, and will not be described again.

As an example, referring to fig. 15, 17 and 18, the electronic device 10 may include a key assembly 126 connected to the housing assembly 121, where the key assembly 126 is capable of pressing the tact switch 1227 on the circuit board 1221 in a pressing direction (e.g., a direction indicated by an arrow D8 in fig. 17) under an external force to expand a control function of the electronic device 10, for example, to implement on/off of the electronic device 10, and further, for example, to implement volume up/down of the electronic device 10. Wherein, the outer side of the shell assembly 121 can be provided with a concave area 1218, and the bottom of the concave area 1218 is provided with a key through hole 1219; the key assembly 126 may be partially located within the recessed area 1218 and extend into the housing assembly 121 via the key through hole 1219 to access the tact switch 1227.

In some embodiments, the number of key assemblies 126 may be two, one for at least effecting a volume up of the electronic device 10 and the other for at least effecting a volume down of the electronic device 10. For example: two key assemblies 126 are respectively used to implement volume up/down of the electronic device 10, wherein one key assembly 126 is further multiplexed to implement power on/off of the electronic device 10. In fig. 17 and fig. 18, two key assemblies 126 may be disposed in respective concave regions 1218, and the two concave regions 1218 are disposed at intervals and extend into the housing assembly 121 through respective key through holes 1219, so that the two key assemblies 126 are independent of each other and do not interfere with each other. Accordingly, the number of the tact switches 1227 may be two, and the tact switches are respectively arranged in one-to-one correspondence with the two key assemblies 126.

In some embodiments, the number of key assemblies 126 may be one, for example, for powering on/off the electronic device 10.

As an example, referring to fig. 15, 17 and 18, the key assembly 126 may include a key 1261 and a sealing ring 1262, the key 1261 may be partially located in the recess 1218 and extend into the housing assembly 121 through the key through hole 1219 to allow the key assembly 126 to press the tact switch 1227 in the pressing direction D8 under an external force, and the sealing ring 1262 may be located in the recess 1218 and surround the key through hole 1219 to seal the key through hole 1219. In addition, since the sealing ring 1262 has a certain compression amount, the sealing ring 1262 can provide a certain damping and rebound feeling in the process of operating the key 1261 by a user. The seal ring 1262 shown in fig. 17 is in a form before compression, and has a certain deformation amount after compression, so as to be elastically supported between the key 1261 and the housing assembly 121. Of course, in other embodiments, the side of the key 1261 facing the housing assembly 121 may be provided with a seal groove for receiving the seal ring 1262.

As an example, referring to fig. 17, 18 and 22, the key 1261 may include an operation portion 12611, a plug post 12612 connected to the operation portion 12611, and a fastening portion 12613 connected to the plug post 12612, where the operation portion 12611 may be at least partially located in the recess 1218 and supported on the seal ring 1262, the plug post 12612 extends into the housing assembly 121 through the seal ring 1262 and the key through hole 1219, and the fastening portion 12613 is fastened to an inner side wall of the housing assembly 121, that is, the fastening portion 12613 is located on an inner side of the housing assembly 121 facing the circuit board 1221, so that the key 1261 is fastened to the housing assembly 121. At this time, the sealing ring 1262 may have a compression amount, so as to provide a seal between the key 1261 and the bottom of the recess 1218, that is, the sealing ring 1262 may be pressed simultaneously when the key 1261 is connected to the housing assembly 121, thereby increasing the tightness of the electronic device 10 at the key through hole 1219, which is simple and reliable. Of course, in other embodiments, in order to achieve the snap-fixing of the button 1261 and the housing assembly 121, the button 1261 may not include the fastening portion 12613, for example, an additional retainer such as a snap ring or a latch independent of the button 1261 may be provided, and the retainer is located on the inner side of the housing assembly 121 facing the circuit board 1221 after being assembled with the button 1261.

As an example, referring to fig. 17 and 22, the socket post 12612 may be provided in a cylindrical shape, and one end of the socket post 12612 facing away from the operation portion 12611 may be provided with at least two slots 12614 extending along an axial direction of the socket post 12612, for example, two slots 12614 may divide the socket post 12612 into a first post segment 12615 adjacent to the operation portion 12611 and a second post segment 12616 remote from the operation portion 12611 along the axial direction of the socket post 12612 as shown in fig. 22. Wherein, the first column section 12615 is continuously arranged along the circumferential direction of the plug-in column 12612, and the sealing ring 1262 is sleeved on the first column section 12615, so that the sealing ring 1262 seals the key through hole 1219; the second post 12616 has a plurality of socket arms (not shown in fig. 17 and 22) spaced apart along the circumference of the socket post 12612, and the number of the fastening portions 12613 is the same as the number of the socket arms and is connected in a one-to-one correspondence.

Further, a side of the key through hole 1219 facing away from the circuit board 1221 may be provided with a first guide surface (not labeled in fig. 17 and 18), and the fastening portion 12613 may be provided with a second guide surface 12617. In this way, during the process of inserting the key 1261 into the housing assembly 121, the second guiding surface 12617 and the first guiding surface cooperate with each other to bring the above-mentioned plugging arms close to each other, so that the fastening portion 12613 passes through the key through hole 1219.

As an example, referring to fig. 17, the key assembly 126 may include an elastic adaptor 1263 connected to the key 1261, the elastic adaptor 1263 having a hardness smaller than that of the key 1261, and the key 1261 presses the tact switch 1227 through the elastic adaptor 1263, thereby providing a certain damping and rebound feeling during the operation of the key 1261 by the user. The material of the button 1261 may be polycarbonate or at least one of glass fiber and carbon fiber, and the material of the elastic adapter 1263 may be silica gel, rubber, etc. Further, a portion of the elastic adapter 1263 may be inserted into the second post 12616, and another portion protrudes from an end of the key 1261 facing the tact switch 1227, so that the key 1261 presses the tact switch 1227 through the elastic adapter 1263.

As an example, in conjunction with fig. 17 and 18, the recess region 1218 may include a first sub-recess region 12181 and a second sub-recess region 12182, the first sub-recess region 12181 being closer to the circuit board 1221 than the second sub-recess region 12182 in the pressing direction D8, the second sub-recess region 12182 having a larger size in a direction perpendicular to the pressing direction D8 than the first sub-recess region 12181. In short, the depression 1218 is divided into two sub-areas in the pressing direction D8, and the key through hole 1219 is provided at the bottom of the first sub-depression 12181. Wherein the sealing ring 1262 may be partially located in the first sub-recessed area 12181, and the operating portion 12611 may be at least partially located in the second sub-recessed area 12182. In this way, during the movement of the button 1261 in the pressing direction D8 relative to the housing assembly 121, the operation portion 12611 can be stopped by the bottom of the second sub-recess 12182, so as to avoid excessive pressing of the button 1261 and excessive deformation of the sealing ring 1262, thereby controlling the stroke of the button 1261 and prolonging the service life of the sealing ring 1262.

Further, on a reference section parallel to the pressing direction D8, the side wall of the first sub-recess 12181 may be at least partially disposed in an arc shape, so that the bottom of the first sub-recess 12181 and the side wall thereof are in an arc transition, thereby reducing (or even eliminating) the gap between the sealing ring 1262 and the housing assembly 121, and further increasing the sealing effect of the sealing ring 1262 on the key through holes 1219.

As an example, referring to fig. 15 to 18 and 22, a first limiting structure 1271 may be disposed in the recess 1218, the first limiting structure 1271 may be located outside the sealing ring 1262, and a second limiting structure 1272 may be disposed on the operating portion 12611. In a non-pressed state of the key assembly 126 under no external force, the first and second limiting structures 1271 and 1272 may partially overlap in the pressing direction D8 and cooperate with each other to limit the keys 1261 in the circumferential direction of the key through holes 1219. In this way, it is advantageous to maintain the relative positions of the keys 1261 and the case assembly 121 in the circumferential direction of the key through-holes 1219, so as to avoid how small or too large a gap between the operation portion 12611 and the case assembly 121 in the radial direction of the key through-holes 1219. In addition, during the movement of the button 1261 along the pressing direction D8 relative to the housing assembly 121, the operation portion 12611 may be stopped by the first limiting structure 1271, and/or the second limiting structure 1272 may abut against the housing assembly 121, so as to avoid over-pressing of the button 1261 and excessive deformation of the sealing ring 1262, thereby controlling the stroke of the button 1261 and prolonging the service life of the sealing ring 1262.

As an example, referring to fig. 15 to 18 and 22, the first limiting structure 1271 may include two first limiting blocks 12711 spaced apart in a circumferential direction of the key through hole 1219, and a blind hole 12712 disposed at a bottom of the recess 1218 and located between the two first limiting blocks 12711; the second stop structure 1272 may include a groove 12721 and a second stop 12722 partially disposed within the groove 12721, the groove 12721 partially thinning the operating portion 12611. In the non-pressing state, the second limiting block 12722 is located between the two first limiting blocks 12711; when the key assembly 126 is pressed by an external force, the second limiting block 12722 extends into the blind hole 12712, and the two first limiting blocks 12711 extend into the grooves 12721 respectively. In this way, not only can the keys 1261 be limited in the circumferential direction of the key through-holes 1219, but also the size of the housing assembly 121 in the pressing direction D8 can be advantageously reduced when the key assembly 126 has a preset stroke. Accordingly, the first stop 12711 may be positioned within the second sub-recess 12182 and the blind hole 12712 may extend to the bottom of the first sub-recess 12181 such that the depth of the blind hole 12712 is sufficiently large to allow sufficient travel of the key assembly 126.

In some embodiments, the distance between the two first limiting blocks 12711 in the circumferential direction of the key through hole 1219 may be greater than the aperture of the blind hole 12712 in the circumferential direction of the key through hole 1219, and a guiding cambered surface or guiding inclined surface is disposed on the edge of the blind hole 12712 near the first limiting block 12711, so that the second limiting block 12722 extends into the blind hole 12712.

In some embodiments, the spacing of the two first stoppers 12711 in the circumferential direction of the key through hole 1219 may be equal to the aperture of the blind hole 12712 in the circumferential direction of the key through hole 1219, so that the second stoppers 12722 extend into the blind hole 12712.

As an example, in connection with fig. 15 to 18 and 22, the number of the first and second limiting structures 1271 and 1272 may be two, respectively, and the two first and second limiting structures 1271 and 1272 may be disposed at opposite intervals in the radial direction of the key through hole 1219, respectively. In this way, it is advantageous not only to further maintain the relative positions of the keys 1261 and the case assembly 121 in the circumferential direction of the key through holes 1219, but also to make the stroke of the keys 1261 controlled more smoothly.

As an example, referring to fig. 15, 17 and 18, the recess 1218, the key through hole 1219, etc. may be located at the bottom of the housing 1211 opposite to the end cap 12121, so that structural components of the key assembly 126, etc. are fixed at the bottom of the housing 1211, so that the user can operate the key assembly 126 in a wearing state.
