Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The inventors of the present application have found, through long-term research: on one hand, because the microphone needs to be communicated with the external environment through the sound pickup hole on the electronic device to pick up the user sound and/or the environmental sound, there is no good hole-free design scheme at present, that is, it is difficult to consider both the sound pickup effect of the microphone and the hole-free design thereof at present. On the other hand, although the traditional physical keys such as a power key and a volume key can be replaced by the pressure sensing type virtual keys, the capacitance type virtual keys and the like at present, and the virtual keys can also realize the function of a reset key in a functional integration mode; however, a separate control circuit is required for the virtual key to implement the reset function of the reset key. The reset function mainly means that the electronic device can be restarted by pressing a reset key after the electronic device is halted. However, in the daily use of the electronic device, the frequency of use of the reset key is not so high, and the position of the reset key is generally hidden (for the purpose of preventing accidental touch). For example: the reset key can be arranged in the electronic equipment, a reset hole corresponding to the reset key is formed in the shell of the electronic equipment, and a user can press the reset key through the reset hole by means of a clamping needle tool. Therefore, the design scheme of hole reduction is provided in a new way, the pickup hole of the microphone and the reset hole of the reset key are compounded, and the effect of one hole with multiple purposes is obtained. That is, although there is only one hole in the appearance of the electronic device, the hole can realize the sound collecting function of the microphone and the reset function of the reset key. The method comprises the following specific steps:

referring to fig. 1, fig. 1 is an exploded schematic view of an embodiment of an electronic device provided in the present application.

The electronic device 10 of the present embodiment may be a portable device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. The present embodiment is described by taking the electronic device 10 as a mobile phone as an example.

The electronic device 10 includes a housing 11, a display 12, a microphone assembly 13, and a reset key 14.

The display 12 is covered on the housing 11 to form an accommodating space, and the microphone assembly 13 and the reset key 14 are both disposed in the accommodating space. In addition, the accommodating space can be used for setting functional components such as a camera module, a fingerprint module, a processor and a battery, so that the electronic device 10 can realize functions such as photographing, unlocking and payment. Further, the housing 11 may be made of metal, glass, or the like. The display screen 12 may be an lcd (liquid Crystal display) screen or an OLED (Organic Light-Emitting Diode) screen; the display screen 12 may be a flat screen, a hyperboloid screen, or a four-curved screen in appearance.

It should be noted that, for the mobile phone, the flat screen refers to the display 12 in a flat plate shape; the hyperboloid screen is that the left and right edge areas of the display screen 12 are arranged in a curved shape, and other areas are still arranged in a flat shape, so that the black edge of the display screen 12 can be reduced, the visible area of the display screen 12 can be increased, and the aesthetic appearance and the holding hand feeling of the electronic device 10 can be increased; the four-curved-surface screen is that the upper, lower, left and right edge regions of the display screen 12 are all in a curved arrangement, and other regions are still in a flat arrangement, as shown in fig. 1, so that the black edge of the display screen 13 can be further reduced, the visible region of the display screen 12 can be increased, and the aesthetic appearance and the holding hand feeling of the electronic device 10 can be further increased.

Herein, all directional indications (such as up, down, left, right, front, and rear … …) in the present application are only used to explain the relative position relationship between the components, the movement, etc. in a specific posture (as shown in fig. 1), and if the specific posture is changed, the directional indication is changed accordingly.

Further, the housing 11 defines a through hole 111, and the through hole 111 is used for enabling the local area inside the electronic device 10 to communicate with the external environment. The microphone assembly 13 is attached to the housing 11, and the microphone assembly 13 is communicated with the through hole 111 through the sound transmission channel, so that the user sound or the environmental sound can be picked up by the microphone assembly 13 through the sound transmission channel. The reset key 14 is provided in the sound transmission passage, and the reset key 14 can be operated through the through hole 111. For example: the user can press the reset key 14 via the through-hole 111 by means of a bayonet-like tool. With such an arrangement, the through hole 111 can not only meet the pickup requirement of the microphone assembly 13, but also meet the reset requirement of the reset key 14, so that the effect of "one hole is multipurpose" can be obtained, and the overall consistency of the electronic device 10 in appearance can be further improved.

In some embodiments, the microphone assembly 13 may be a primary microphone assembly for picking up user sounds, typically disposed in a bottom region of the electronic device 10. Accordingly, the through-hole 111 may open in the bottom region of the housing 11. In other embodiments, the microphone assembly 13 may also be a secondary microphone assembly for picking up ambient sounds. Accordingly, the through-hole 111 may be opened in the back region of the housing 11, as shown in fig. 2. Moreover, the through hole 111 may be close to an existing lens hole for placing the rear camera module and/or a fingerprint hole for placing the rear fingerprint module on the electronic device 10. Since the lens and/or fingerprint apertures 112 are typically much larger in geometric dimension than the through-holes 111, this may allow the user to have the illusion that the through-holes 111 are "hidden" from view, thereby increasing the uniformity of the overall appearance of the electronic device 10.

Referring to fig. 3, fig. 3 is a schematic partial cross-sectional structure diagram of the electronic device in fig. 1 after assembly.

The microphone assembly 13 includes a bracket 131 and a microphone 132. The bracket 131 is opened with a housing 1311. The holder 131 is attached to the housing 11 so that the housing 1311 communicates with the through-hole 111. The housing 1311 serves as a sound transmission path, and the reset key 14 is provided in the housing 1311. Further, a first adhesive member 133 is disposed on a surface of the bracket 131 close to the housing 11, and the first adhesive member 133 is used for fixing the bracket 131 and the housing 11. The first adhesive member 133 is disposed around the receiving portion 1311, so that the first adhesive member 133 not only can perform the above-mentioned fixing function, but also can perform the function of sealing the receiving portion 1311, thereby increasing the sound collecting effect of the microphone 132 and increasing the reliability of the microphone assembly 13. The first adhesive member 133 may be a sealing foam, a sealing tape, or the like.

In some embodiments, the receptacle 1311 may be a blind hole having a depth, the receptacle 1311 opening toward the housing 11, as shown in fig. 3. At this moment, the reset key 14 can be fixed in the bottom of the blind hole through any one of gluing, clamping, welding and the like, and is arranged opposite to the through hole 111, so that the reset key 14 can be controlled by a user through the through hole 111. Furthermore, since the housing 1311 is in communication with the through hole 111, the microphone 132 may be disposed at any position in the housing 1311, and the microphone 132 may be in communication with the external environment through the housing 1311 and the through hole 111. In the present embodiment, the microphone 132 is disposed at the bottom of the blind hole, that is, the microphone 132 and the reset key 14 are disposed side by side relative to the bottom of the blind hole. Of course, the microphone 132 may also be fixed to the bottom of the blind hole by any one of gluing, clamping, and welding. Further, the reset key 14 and the microphone 132 may be electrically connected to the main board of the electronic device 10 through the opening of the receiving portion 1311 to reduce the number of openings on the bracket 131, thereby increasing the sealing effect of the microphone assembly 13 and ensuring the sound pickup effect of the microphone 132.

In other embodiments, the receiving portion 1311 may be a through hole penetrating through the bracket 131, that is, the receiving portion 1311 is not only opened toward one end of the housing 11, but also opened away from one end of the housing 11, as shown in fig. 4 and 5. At this time, the microphone assembly 13 further includes a support 134. The supporting element 134 is attached to a surface of the bracket 131 far away from the housing 11, and an end of the through hole close to the supporting element 134 is hermetically disposed, so as to ensure a sound pickup effect of the microphone 132. Of course, in order to meet the requirements of adhesion and sealing between the support 134 and the bracket 131, a second adhesive member 135 is further disposed on one surface of the bracket 131 close to the support 134, and the second adhesive member 135 is disposed around the receiving portion 1311. The second adhesive member 135 may be a sealing foam, a sealing tape, or the like.

Further, the reset key 14 and the microphone 132 may be fixed to the supporting member 134 by any one of gluing, clamping, and welding. The reset key 14 is accommodated in the accommodating portion 1311 when fixed to the support 134. When the microphone 132 is fixed to the supporting member 134, it can be accommodated in the accommodating portion 1311, i.e. on the same side as the reset key 14, as shown in fig. 4; or on the side of the supporting member 134 away from the bracket 131, i.e., on the opposite side of the reset key 14, as shown in fig. 5. In the latter case, the support 134 is opened with a sound transmitting hole 1341 so that the microphone 132 communicates with the receiving portion 1311 via the sound transmitting hole 1341, thereby enabling the microphone 132 to pick up the user's voice or the ambient sound.

The supporting element 134 may be a circuit board, so that the reset key 14 and the microphone 132 can be directly electrically connected to the supporting element 134, thereby simplifying the electrical connection between the reset key 14 and the microphone 132 and the main board of the electronic device 10. Specifically, the supporting member 134 may be a rigid circuit board or a flexible circuit board. If the supporting member 134 is a flexible circuit board, it may be reinforced, and especially, the supporting member 134 is used to fix the position of the reset key 14, so as to reduce the risk that the flexible circuit board will be broken during the process of implementing the reset function of the reset key 14.

Referring to fig. 6 and 7 together, fig. 6 is a schematic cross-sectional view of another embodiment of the microphone assembly shown in fig. 1, and fig. 7 is a schematic top view of the bracket shown in fig. 6.

The main differences from the above described embodiment are: in this embodiment, the bracket 131 is further provided with a partition 1312, and the partition 1312 partitions the housing 1311 into a first housing 1313 and a second housing 1314. Second receiving portion 1314 communicates with first receiving portion 1313. For example, a groove 1315 is formed on a surface of the partition 1312 close to the housing 11, one end of the groove 1315 is communicated with the first receiving portion 1313, and the other end of the groove 1315 is communicated with the second receiving portion 1314. The first receiving portion 1313 and the second receiving portion 1314 may be through holes having a regular shape such as a cylindrical shape or a square shape, or may have other irregular shapes. The cross section of the groove 1315 may be in the shape of a semicircle, a rectangle, a triangle, or other irregular shapes.

The reset key 14 is located in the first receiving portion 1313, and the first receiving portion 1313 may be opposite to the through hole 111, as shown in fig. 6, so that the reset key 14 can be manipulated through the through hole 111 and the first receiving portion 1313. Further, the microphone 132 may be located in the second receiving portion 1314, similar to the structure shown in fig. 4 and will not be described herein again. The microphone 132 may also be attached to a side of the support 134 away from the bracket 131, as shown in fig. 6. At this time, the microphone 132 communicates with the second receiving portion 1314 through the sound transmitting hole 1341.

In the present embodiment, the first receiving portion 1313 and the second receiving portion 1314 are cylindrical through holes for example. The parameters such as the aperture and the shape of the first receiving portion 1313 can be designed appropriately according to the shape of the reset key 14. In contrast, second receiving portion 1314 and recess 1315 are primarily for sound transmission. Therefore, the parameters such as the size and shape of the second receiving part 1314 and the groove 1315 can be set more flexibly, and only the sound transmission effect of the second receiving part 1314 and the groove 1315 needs to be ensured or increased. Further, in the present embodiment, the second receiving portion 1314 is similar to the first receiving portion 1313, so that the processing of the bracket 131 can be simplified. Since groove 1315 is used primarily to connect first receptacle 1313 to second receptacle 1314, the width of groove 1315 may be greater than the radius of first receptacle 1313 and less than the diameter of first receptacle 1313; furthermore, the grooves 1315 may be symmetrically arranged along a line connecting centers of the first receiving portion 1313 and the second receiving portion 1314, as shown in fig. 7. Of course, in other embodiments, second receptacle 1314 may be different than first receptacle 1313, and the width of groove 1315 may be other dimensions.

Further, the microphone assembly 13 may further include an elastic member 136. The elastic element 136 is embedded in the first receiving portion 1313 and away from the groove 1315, and the elastic element 136 is located between the reset key 14 and the housing 11, as shown in fig. 6. In this embodiment, the depth of the groove 1315 does not exceed the position of the elastic member 136, so that the elastic member 136 and the hole wall of the first receiving portion 1313 can form a sealing structure. The arrangement is such that the reset key 14 and the microphone 132 are respectively located in two relatively independent spaces, which can reduce mutual interference between the two to some extent, thereby increasing the reliability of the electronic device 10. Meanwhile, the through hole 111, the first receiving portion 1313 (a portion near the groove 1315), the groove 1315, the second receiving portion 1314, and the sound transmitting hole 1341 serve as a sound transmitting passage of the microphone 132.

On the one hand, when the user presses the elastic member 136 through the through hole 111 by means of the card pin 100, the elastic member 136 can be elastically deformed toward the reset key 14, as shown in fig. 8, so that the reset key 14 can be touched. After the user removes the card needle 100, the elastic member 136 can be elastically restored to the initial state, as shown in fig. 6, so that the operation state of the reset key 14 can be released. Further, the elastic member 136 may be glued or clipped to the first receiving portion 1313, so that the relative position between the elastic member 136 and the bracket 131 is kept unchanged, and the elastic member 136 can be elastically deformed, thereby increasing the reliability of the bracket assembly 131. Of course, in other embodiments, when the user presses the elastic member 136 through the through hole 111 by using the card pin 100, the elastic member 136 may slightly move toward the reset key 14, so that the reset key 14 can be touched as well; the elastic member 136 can also move to the initial position after the user removes the card needle 100, so that the operation state of the reset key 14 can be released as well.

On the other hand, for the reset key 14, the elastic member 136 also needs to play a role of isolating moisture, dust, etc. to prolong the service life of the reset key 14. For the microphone 132, the elastic member 136 also needs to seal the sound transmission channel formed by the first receiving portion 1313, the second receiving portion 1314 and the groove 1315 to prevent the picked-up user sound or environmental sound from leaking to the reset key 14, and/or prevent noise at the reset key 14 and other positions from mixing with the user sound or environmental sound, so as to ensure the sound pickup effect of the microphone 132.

In order to meet the above requirements, the elastic member 136 needs to have a certain structural strength to prevent the needle 100 from being punctured and a certain sound insulation effect. Further, when the elastic member 136 is embedded in the first receiving portion 1313, the elastic member 136 itself can be slightly deformed to abut against the hole wall of the first receiving portion 1313, thereby increasing the sealing property between the elastic member 136 and the bracket 131. Therefore, the elastic member 136 may be made of a flexible material, such as silicone rubber, etc.

Further, the distance between the reset key 14 and the elastic member 136 is less than or equal to a preset amount of deformation of the elastic member 136 in the thickness direction thereof, so that the elastic member 136 can be elastically deformed toward the reset key 14 via the through hole 111, thereby enabling the reset key 14 to be manipulated. In other words, when the elastic member 136 is elastically deformed by the pressing of the card holder 100, the reset key 14 can touch within the predetermined deformation range. Preferably, the reset key 14 abuts against the elastic member 136 to reduce the amount of deformation required of the elastic member 136 when the reset key 14 is touched.

Based on the above description, the reset key 14 can achieve the waterproof and dustproof requirements with the external environment through the elastic member 136; the microphone 132 is directly connected to the external environment through the sound hole 1341, the second receiving portion 1314, the groove 1315, the first receiving portion 1313 (a portion close to the groove 1315) and the through hole 111, and additional waterproof and dustproof arrangements are required for the microphone 132. For this reason, the microphone assembly 13 may further include a waterproof member 137, and the waterproof member 137 is disposed in the recess 1315 and/or the second receiving portion 1314, that is, the waterproof member 137 is isolated in the sound transmission channel formed by the bracket 131, so as to prevent the microphone 132 from directly communicating with the external environment. In the present embodiment, the water-proof member 137 fills a part or the whole of the second receiving portion 1314, as shown in fig. 6, so as to satisfy the waterproof and dustproof requirements between the microphone 132 and the external environment, and not affect the sound transmission, thereby increasing the reliability of the microphone 132. Waterproof member 137 may be made of a polymer material with waterproof and air-permeable properties, such as polytetrafluoroethylene. Of course, in some other embodiments, the waterproof member 137 may also be disposed in a film shape, attached to the support 134, and covered on the sound hole 1341, so that the waterproof member 137 forms a waterproof and air-permeable barrier between the second receiving portion 1314 and the sound hole 1341, and the barrier can also fulfill the waterproof and dustproof requirements between the microphone 132 and the external environment.

Further, other structures of the present embodiment are the same as or similar to those of the above embodiments, and are not described herein again.

Referring to fig. 9 and 10 together, fig. 9 is a schematic cross-sectional view of another embodiment of the bracket in fig. 6, and fig. 10 is a schematic top view of a side of the bracket near the housing in fig. 9.

The main differences from the above described embodiment are: in this embodiment, the second receiving portion 1314 and the groove 1315 are designed to have a gradually changing structure. For example, in the sound transmission channel composed of the through hole 111, the first receiving portion 1313 (a portion near the groove 1315), the groove 1315, the second receiving portion 1314, and the sound transmission hole 1341, the cross-sectional size of the sound transmission channel may be gradually reduced to form a funnel-like shape. The funnel-shaped structure formed by the arrangement can increase the collection effect of the sound transmission channel on sound, thereby increasing the sound pickup effect of the microphone 132.

Wherein, the width of the groove 1315 may gradually become larger in the direction from the first receiving portion 1313 to the second receiving portion 1314, as shown in fig. 10; the depth may gradually increase in a direction from first receiving portion 1313 toward second receiving portion 1314, as shown in fig. 9. The aperture of the second receiving portion 1314 may be gradually smaller in the direction from the housing 11 toward the display 12, as shown in fig. 9. The through hole 111, the first receiving portion 1313 (a portion close to the groove 1315), and the sound-transmitting hole 1341 may not be subjected to gradation processing similar to that described above because the ratio of the three in the entire sound-transmitting passage is not so large.

Further, other structures of this embodiment are the same as or similar to those of any of the above embodiments, and are not repeated herein.

Referring to fig. 11, fig. 11 is a schematic cross-sectional structure diagram of another embodiment of the microphone assembly shown in fig. 6.

The main differences from any of the above embodiments are: in this embodiment, the first receiving portion 1313 is a stepped hole. The first receiving portion 1313 includes a first sub-receiving portion 13131 and a second sub-receiving portion 13132. First sub-receiving portion 13131 is separated from groove 1315, and forms step 13133 with second sub-receiving portion 13132. Further, the depth of the groove 1315 is smaller than the depth of the second sub-receiving portion 13132, and the elastic member 136 is attached to the stepped surface 13133, so that the elastic member 136 can meet the waterproof and dustproof requirements between the reset key 14 and the external environment.

In some embodiments, as shown in fig. 11, the aperture of first sub-reservoir 13131 is larger than the aperture of second sub-reservoir 13132. At this time, the elastic member 136 is fitted in the first sub-receiving portion 13131 and abuts against the stepped surface 13133. Similarly, the distance between the reset key 14 and the elastic member 136 is less than or equal to a preset amount of deformation of the elastic member 136 in the thickness direction thereof. Preferably, the reset key 14 abuts against the elastic member 136 to reduce the amount of deformation of the elastic member 136 when the reset key 14 is touched, and to prevent the elastic member 136 from separating from the stepped surface 13133 under the action of an external force. Further, the elastic member 136 may be glued to the stepped surface 13133 to increase the firmness between the elastic member 136 and the bracket 131.

In other embodiments, as shown in fig. 12, the aperture of the second sub-receiving portion 13132 is larger than the aperture of the first sub-receiving portion 13131, and the elastic member 136 is embedded in the second sub-receiving portion 13132 and abuts against the stepped surface 13133. Similarly, the distance between the reset key 14 and the elastic member 136 is less than or equal to a preset amount of deformation of the elastic member 136 in the thickness direction thereof. Preferably, the reset key 14 abuts against the elastic member 136 to reduce the amount of deformation of the elastic member 136 when the reset key 14 is touched, and to prevent the elastic member 136 from separating from the stepped surface 13133 under the action of an external force. Further, the elastic member 136 may be glued to the stepped surface 13133 to increase the firmness between the elastic member 136 and the bracket 131. In this embodiment, the difference between the depth of the second sub-receiving portion 13132 and the depth of the groove 1315 is greater than or equal to the thickness of the elastic member 136, so as to prevent the edge of the elastic member 136 from tilting and separating from the stepped surface 13133 under the action of external force, and further ensure the waterproof and dustproof requirements between the reset key 14 and the external environment, thereby increasing the reliability of the reset key 14.

Based on the above description, the elastic member 136 of the present embodiment may be made of a rigid material, such as a metal sheet with excellent ductility, such as a copper foil or an aluminum foil, in addition to a flexible material, such as silicon gel or rubber. These metal sheets may also be elastically deformed by an external force, so that the reset key 14 can be touched.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
