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.

Referring to fig. 1, an ear 100 of a user may include physiological sites such as an external auditory canal 101, a concha cavity 102, a concha boat 103, a triangular fossa 104, an antitragus 105, a tragus 106, an auricle 107, and an antitragus 108. Although the external auditory canal 101 has a certain depth and extends to the tympanic membrane of the ear, for convenience of description, and in connection with fig. 1, the external auditory canal 101 refers specifically to an entrance (i.e., an earhole) thereof facing away from the tympanic membrane, unless specifically described herein. Further, physiological parts such as the concha cavity 102, the concha boat 103, the triangular fossa 104 and the like have a certain volume and depth; and the concha cavity 102 is in direct communication with the external auditory meatus 101, i.e., can be simply considered as the aforementioned earhole being located at the bottom of the concha cavity 102.

Further, individual differences may exist for different users, resulting in different size differences in the shape, size, etc. of the ears. For ease of description, and to reduce (or even eliminate) individual differences among different users, a simulator having a head and its (left and right) ears, such as a GRAS 45BC KEMAR, may be made based on ANSI: S3.36, S3.25 and IEC:60318-7 standards. Thus, in this application, descriptions such as "the user wears the earphone," "the earphone is in a worn state," and "in a worn state," may refer to the earphone described in this application being worn on the ear of the aforementioned simulator. Of course, because of individual differences among different users, the headset may be worn by different users with a certain difference from the ear of the headset worn on the simulator, but such a difference should be tolerated.

It should be noted that: in the fields of medicine, anatomy, etc., three basic tangential planes of the Sagittal Plane (Sagittal Plane), the Coronal Plane (Coronal Plane) and the Horizontal Plane (Horizontal Plane) of the human body, and three basic axes of the Sagittal Axis (Sagittal Axis), the Coronal Axis (Coronal Axis) and the Vertical Axis (Vertical Axis) may be defined. The sagittal plane is a section perpendicular to the ground and is divided into a left part and a right part; the coronal plane is a tangential plane perpendicular to the ground and is formed along the left-right direction of the body, and divides the human body into a front part and a rear part; the horizontal plane refers to a section parallel to the ground along the up-down direction of the body, and divides the human body into an upper part and a lower part. Accordingly, the sagittal axis refers to an axis along the anterior-posterior direction of the body and perpendicular to the coronal plane, the coronal axis refers to an axis along the lateral direction of the body and perpendicular to the sagittal plane, and the vertical axis refers to an axis along the superior-inferior direction of the body and perpendicular to the horizontal plane. Further, the term "front side of an ear" as used herein is a concept of "back side of an ear" with respect to the side of the ear facing away from the head, and the side of the ear facing toward the head, all for the user's ear. The front outline schematic diagram of the ear shown in fig. 1 can be obtained by observing the ear of the simulator along the direction of the coronal axis of the human body.

As an example, referring to fig. 2 and 3, the earphone 10 may include a deck module 11 and a hook structure 12 connected to the deck module 11, the deck module 11 being positioned at a front side of an ear in a wearing state, and at least a portion of the hook structure 12 being positioned at a rear side of the ear in a wearing state, such that the earphone 10 is hung on the ear in the wearing state. Wherein the deck module 11 may be arranged not to block the external auditory meatus in a worn state, such that the earphone 10 functions as an "open earphone". Notably, are: because of individual differences among different users, when the earphone 10 is worn by different users, the external auditory meatus may be partially blocked by the core module 11, but the external auditory meatus is still not blocked.

To improve the stability of the earphone 10 in the worn state, the earphone 10 may employ any one of the following or a combination thereof. First, at least a portion of the hook structure 12 is configured as a contoured structure that conforms to at least one of the rear side of the ear and the head to increase the contact area of the hook structure 12 with the ear and/or the head, thereby increasing the resistance to the earphone 10 falling off of the ear. Secondly, at least part of the hook-shaped structure 12 is provided as an elastic structure, so that the hook-shaped structure has a certain deformation amount in a wearing state, so that the positive pressure of the hook-shaped structure 12 on the ear and/or the head is increased, and the resistance of the earphone 10 falling off from the ear is increased. Thirdly, the hook structure 12 is at least partially arranged to abut against the head in the wearing state, so that a reaction force for pressing the ear is formed, so that the movement module 11 is pressed against the front side of the ear, and the resistance of the earphone 10 falling off from the ear is increased. Fourth, the movement module 11 and the hook-shaped structure 12 are arranged to clamp physiological parts such as the region where the antitragus is located, the region where the concha cavity is located, and the like from the front side and the rear side of the ear in the wearing state, so that the resistance of the earphone 10 falling off from the ear is increased. Fifthly, the movement module 11 or an auxiliary structure connected with the movement module is arranged to extend into physiological parts such as the concha cavity, the concha boat, the triangular fossa, the ear boat and the like at least partially, so that the resistance of the earphone 10 falling off from the ear is increased.

As an example, in connection with fig. 1 to 3, the earphone 10 may include an auxiliary structure 15 connected to the deck module 11, at least part of the auxiliary structure 15 being located on the front side of the ear in the worn state, i.e., at least part of the auxiliary structure 15 being located on the same side of the ear as the deck module 11 in the worn state, to assist the deck module 11 in the worn state. Under the wearing state, the movement module 11 is pressed in a first ear area corresponding to the concha boat, and the auxiliary structure 15 is pressed in a second ear area corresponding to the antitragus, that is, the movement module 11 and the auxiliary structure 15 are pressed in different areas on the ear. Therefore, compared with the earphone 10, which is only provided with the core module 11, the earphone 10 is further provided with the auxiliary structure 15 matched with the core module 11, so that the contact area between the earphone 10 and the front side of the ear is increased, and the situation that the acting force between the earphone 10 and the front side of the ear is concentrated in a smaller area is avoided, thereby being beneficial to improving the stability and comfort of the earphone 10 in a wearing state. In addition, as seen in the thickness direction of the movement module 11, the distance of the auxiliary structure 15 staggered from the hook-shaped structure 12 is smaller than the distance of the movement module 11 staggered from the hook-shaped structure 12, so that the shearing stress generated by the clamping force of the earphone 10 to the ear is weakened, even converted into the compressive stress, which is beneficial to improving the stability and comfort of the earphone 10 in the wearing state. The thickness direction X may be defined as a direction in which the movement module 11 approaches or separates from the ear in the wearing state.

Further, the auxiliary structure 15 may be detachably connected to the movement module 11 by any one of a buckle, a double-sided tape, a screw, and the like. The earphone 10 may be provided with a plurality of auxiliary structures 15 with the same or different specifications, so as to be convenient for a new or different user to use.

As an example, in connection with fig. 3, in the wearing state and as viewed in the thickness direction X, the auxiliary structure 15 extends in a direction (for example, a dotted arrow A1 in fig. 3) directed rearward of the brain and is at an acute angle to the vertical axis of the human body in a forward direction (for example, a dotted arrow A2 in fig. 3) directed toward the top of the head. In this way, the auxiliary structure 15 is not only convenient to press and hold the ear area corresponding to the anthelix, but also the auxiliary structure 15 can press and hold the middle area with larger area on the anthelix, thus being beneficial to improving the stability and comfort of the earphone 10 in the wearing state.

As an example, in conjunction with fig. 2 to 6, the deck module 11 may have a first inner side IS1 facing the ear portion in the thickness direction X and a first outer side OS1 facing away from the ear portion in the wearing state, and a connection surface connecting the first inner side IS1 and the first outer side OS 1. The auxiliary structure 15 can be connected to at least the aforementioned connection surface, for example, the auxiliary structure 15 can be connected only to the aforementioned connection surface, for example, and the auxiliary structure 15 can be connected to the aforementioned connection surface as well as the first outer surface OS 1. In this way, it is advantageous to control the distance between the auxiliary structure 15 and the hook-like structure 12 in the thickness direction X within a reasonable range, so as to avoid that the aforementioned distance is too small to cause too large a holding force at the auxiliary structure 15 or that the aforementioned distance is too large to cause too small a holding force at the auxiliary structure 15.

It should be noted that: the movement module 11 may be provided in a circular shape, an elliptical shape, a rounded square shape, a rounded rectangular shape, or the like, as viewed in the thickness direction X. When the movement module 11 is arranged in a shape of a circle, an ellipse, or the like, the connection surface may refer to an arc-shaped side surface of the movement module 11; when the deck module 11 is provided in the shape of a rounded square, a rounded rectangle, or the like, the above-described connection surfaces may include a lower side LS, an upper side US, a front side FS, and a rear side RS, which will be described later. Further, the deck module 11 may have a length direction Y and a width direction Z perpendicular to the thickness direction X and orthogonal to each other. The length direction Y may be defined as a direction in which the movement module 11 approaches or moves away from the back of the brain of the user in the wearing state, and the width direction Z may be defined as a direction in which the movement module 11 approaches or moves away from the top of the head of the user in the wearing state. Therefore, for convenience of description, the present application exemplifies that the deck module 11 is provided in a rounded rectangle. The length of the movement module 11 in the length direction Y may be greater than the width of the movement module 11 in the width direction Z. Based on this, the above-mentioned connection surface may include an upper side surface US facing away from the external auditory meatus in the width direction Z and a lower side surface LS facing toward the external auditory meatus in the wearing state, and a rear side surface RS facing toward the rear of the brain in the length direction Y and a front side surface FS facing away from the rear of the brain in the wearing state. The auxiliary structure 15 can be connected to at least the rear side RS, for example, the auxiliary structure 15 can be connected to only the rear side RS, for example, and the auxiliary structure 15 can be connected to the rear side RS as well as the upper side US. In this way, it is advantageous to have the auxiliary structure 15 be mainly pressed against the middle area of the antihelix, which is large.

Further, the thickness of the auxiliary structure 15 may be smaller than the dimension of the deck module 11 in the thickness direction, so as to give consideration to the weight of the earphone 10 and the size thereof. The position where the auxiliary structure 15 is connected to the movement module 11 may be located between one third of the thickness of the movement module 11 in the thickness direction X and two thirds of the thickness, for example, the position where the auxiliary structure 15 is connected to the movement module 11 is located one half of the thickness of the movement module 11 in the thickness direction X, as viewed in the length direction Y or the width direction Z. In this way, it is advantageous to control the distance between the auxiliary structure 15 and the hook-like structure 12 in the thickness direction X within a reasonable range, so as to avoid that the aforementioned distance is too small to cause too large a holding force at the auxiliary structure 15 or that the aforementioned distance is too large to cause too small a holding force at the auxiliary structure 15.

As an example, fig. 5 and 6, and fig. 9 and 10, for example, the hook-like structures 12 and the auxiliary structures 15 are offset in the thickness direction X. In this way, the thickness of the ear can be better adapted to the earphone 10, which is not only beneficial to avoiding the wearing discomfort caused by too large pressure of the auxiliary structure 15 at the anthelix, but also beneficial to avoiding the unstable wearing caused by the auxiliary structure 15 jacking up the movement module 11.

As an example, referring to fig. 7, the auxiliary structure 15 may include a connection portion 151 connected to the deck module 11 and an extension portion 152 connected to the connection portion 151, and the auxiliary structure 15 may be in contact with the antihelix through the extension portion 152. The hardness of the extension 152 may be smaller than that of the movement module 11, for example, the extension 152 is made of plastic, rubber, or the like. In this manner, the extension 152 may be elastically deformed differently when the headset 10 is worn by different users, so that the amount of pressure of the auxiliary structure 15 at the antitragus is appropriate. Of course, the hardness of the connection portion 151 may be smaller than that of the deck module 11 (specifically, the deck case 111 mentioned later), for example, the connection portion 151 is made of the same material as the extension portion 152. Accordingly, the connection portion 151 and the deck module 11 may be detachably connected or non-detachably connected according to the need.

Further, the auxiliary structure 15 may comprise a flexible insert 153 connected to the extension 152, the flexible insert 153 may be provided within the extension 152 or the extension 152 may be directed towards the side of the antihelix. Wherein the hardness of the flexible insert 153 may be less than the hardness of the outer extension 152 to make the portion of the auxiliary structure 15 in contact with the antihelix softer, which is advantageous for improving the stability and comfort of the earphone 10 in the worn state.

As an example, referring to fig. 5 and 6, the connection surface may be provided with a mounting groove extending in the circumferential direction of the deck module 11, and the connection portion 151 may be fixed in the mounting groove. The mounting groove may be formed in an annular shape, or the connection portion 151 may be formed in an annular structure (for example, as shown in fig. 7) to be matched with the mounting groove, and the connection portion 151 may be nested in the mounting groove. Of course, the installation groove may be provided in a C-shape or a U-shape, for example, the installation groove may be provided on the rear side RS and further extend to the lower side LS and the upper side US, the connection portion 151 may be provided in a C-shape or a U-shape structure matching the installation groove, and the connection portion 151 may be embedded in the installation groove.

As an example, in connection with fig. 8 to 10, the connection 151 may cover at least a portion of the first outer side OS1, for example, the first outer side OS1 is entirely covered by the connection 151, i.e., the first outer side OS1 shown in fig. 2 to 6 is not visible in fig. 8 to 10. Thus, the connection area between the connection portion 151 and the movement module 11 can be increased, and the connection portion and the movement module can be connected by gluing, injection molding or the like. Wherein the extension 152 may have a second inner side IS2 facing towards the antihelix and a second outer side OS2 facing away from the antihelix in the worn state, at least one of the second inner side IS2 and the second outer inner side OS2 being inclined towards the antihelix in the extension direction of the auxiliary structure 15. For example: the second inner side IS2 and the second outer inner side OS2 are both inclined in the extension direction of the auxiliary structure 15 towards the antihelix, i.e. the extension 152 IS bent towards the first inner side IS1 relative to the connection 151. In this manner, the extension 152 is facilitated to better contact the antihelix and the thickness of the extension 152 is compromised. Further, referring to fig. 14 and 15, the connection portion 151 may cover at least a part of the connection surface (e.g., the rear surface RS) in addition to at least a part of the first outer surface OS 1. Thus, the connection area between the connection portion 151 and the movement module 11 is increased, and the comfort level of the movement module 11 contacting the ear at the rear side RS is improved.

As an example, referring to fig. 4 and 13, the deck module 11 may include a deck housing 111 connected with the hook structure 12 and a speaker 112 disposed in the deck housing 111. Wherein the inner side surface of the deck case 111 facing the ear in the worn state (for example, the first inner side surface IS1 mentioned above) IS provided with an acoustic outlet 111a (the acoustic outlet may be closer to the lower side surface LS than the upper side surface US), and the acoustic wave generated by the speaker 112 IS propagated out through the acoustic outlet 111a so as to be transmitted into the external auditory meatus. Notably, are: the sound emitting hole 111a may be provided at a side of the deck case 111 corresponding to the lower side LS, and may be provided at a corner between the inner side and the lower side LS.

Further, referring to fig. 13 and fig. 2 to 11, the earphone 10 may include a main control circuit board 13 disposed in the deck housing 111 and a battery 14 disposed at an end of the hook structure 12 away from the deck module 11, and the battery 14 and the speaker 112 are respectively coupled to the main control circuit board 13 to allow the battery 14 to supply power to the speaker 112 under the control of the main control circuit board 13. Of course, the battery 14 and the speaker 112 may be both provided in the deck housing 111.

As an example, in connection with fig. 4 or 11, the deck housing 111 or the auxiliary structure 15 (specifically, the extension 152) may be provided with electrode terminals 16 toward the inside of the ear in the worn state, and the electrode terminals 16 may be coupled with the main control circuit board 13. The number of the electrode terminals 16 may be two, and the electrode terminals may be used as a charging positive terminal and a charging negative terminal of the earphone 10, respectively, so that the earphone 10 can realize a charging function; the number of the electrode terminals 16 may be three, two of which serve as the charging positive terminal and the charging negative terminal of the earphone 10, respectively, and the remaining one serves as the detection terminal of the earphone 10, so that the earphone 10 can perform detection functions such as charging detection, and charging box detection when the earphone 10 is put into or taken out of.

As an example, in connection with fig. 3 and 1, since the concha boat and the concha cavity communicated with the same have a certain volume and depth, the inner side surface (for example, the first inner side surface IS1 mentioned above) of the cartridge case 111 can have a certain distance from the concha boat and the concha cavity after the cartridge module 11 IS pressed against the ear area corresponding to the antitragus. In other words, the movement module 11, in the worn state, may cooperate with the concha boat and the concha cavity to form an auxiliary cavity communicating with the external auditory meatus, and the sound outlet 111a is at least partially located in the aforementioned auxiliary cavity. In this way, in the wearing state, the sound wave generated by the speaker 112 and transmitted through the sound outlet 111a is limited by the auxiliary cavity, that is, the auxiliary cavity can gather the sound wave, so that the sound wave can be transmitted into the external auditory canal more, thereby improving the volume and the quality of the sound heard by the user in the near field, and thus being beneficial to improving the acoustic effect of the earphone 10. Further, since the movement module 11 may be configured not to block the external auditory meatus in the wearing state, the aforementioned auxiliary cavity may be semi-open. In this way, the sound wave generated by the speaker 112 and propagated through the sound outlet 111a propagates to the outside of the earphone 10 and the ear through the gap between the deck module 11 and the ear (for example, a portion of the deck cavity not covered by the deck module 11) in addition to the major portion thereof propagating to the external auditory meatus, thereby forming a first leakage sound in the far field; meanwhile, the movement module 11 is generally provided with an acoustic hole (for example, a pressure relief hole 111c mentioned later), the sound wave propagated out through the acoustic hole generally forms a second leakage sound in the far field, and the phase of the first leakage sound and the phase (near) of the second leakage sound are opposite to each other, so that the two can be opposite to each other in the far field, which is beneficial to reducing the leakage sound of the earphone 10 in the far field.

Further, the earphone 10 may include an adjusting mechanism for connecting the deck module 11 and the hook structure 12, and different users can adjust the relative positions of the deck module 11 on the ears through the adjusting mechanism in the wearing state, so that the deck module 11 is located at a proper position, and thus the deck module 11, the concha boat and the concha cavity form the auxiliary cavity. In addition, the user can also adjust the headset 10 to a more stable, comfortable position due to the presence of the adjustment mechanism.

As an example, in connection with fig. 12, the earphone 10 is first worn on the simulator, then the position of the movement module 11 on the ear of the simulator is adjusted, and then the frequency response curve of the earphone 10 is measured by a detector (e.g., a microphone) disposed in the external auditory canal of the simulator (e.g., where the tympanic membrane is located, that is, where the sound is to be heard), so as to simulate the sound effect of the user wearing the earphone 10. Wherein, the frequency response curve can be used for representing the change relation between the vibration magnitude and the frequency; the abscissa of the aforementioned frequency response curve may represent frequency in Hz; the ordinate of the aforementioned frequency response curve may represent the magnitude of the vibration in dB. In fig. 12, a curve 12_1 may represent a frequency response curve when the movement module 11 does not form the auxiliary cavity with the concha cavity in the wearing state, and a curve 12_2 may represent a frequency response curve when the movement module 11 cooperates with the concha cavity to form the auxiliary cavity in the wearing state. Based on this, it can be directly and unambiguously derived from the comparison of the frequency response curves shown in fig. 12: the curve 12_2 is located above the curve 12_1 as a whole, that is, the auxiliary cavity is formed by the movement module 11 and the concha cavity in the wearing state, which is more beneficial to improving the acoustic effect of the earphone 10 compared with the case that the auxiliary cavity is not formed by the movement module 11 and the concha cavity in the wearing state.

As an example, in conjunction with fig. 14 and 15, the cartridge case 111 may include a cartridge inner case 1111 and a cartridge outer case 1112 that are fastened to each other in the thickness direction X, the cartridge inner case 1111 being closer to the ear in the wearing state than the cartridge outer case 1112. Here, the parting surface 111b between the cartridge case 1112 and the cartridge case 1111 is inclined toward the side where the cartridge case 1111 is located in a direction away from the end (hereinafter simply referred to as "connection end") where the cartridge module 11 is connected to the hook-like structure 12 (for example, a direction indicated by an arrow Y in fig. 14). In this way, the connection portion 151 may be mainly connected with the core housing 1112, which is not only beneficial to increasing the connection area between the auxiliary structure 15 and the core module 11 without increasing the size of the core module 11 in the length direction Y, but also beneficial to simplifying the connection structure between the auxiliary structure 15 and the core module 11.

As an example, referring to fig. 14 and 15, the cartridge inner case 1111 may include a bottom wall 1113 and a first side wall 1114 connected to the bottom wall 1113, the cartridge outer case 1112 may include a top wall 1115 and a second side wall 1116 connected to the top wall 1115, the second side wall 1116 and the first side wall 1114 may be fastened to each other along the parting plane 111b, and both may be supported by each other. The portion of the first side wall 1114 away from the connection end is gradually closer to the bottom wall 1113 in the thickness direction X, and the portion of the second side wall 1116 away from the connection end is gradually farther from the top wall 1115 in the thickness direction X, as viewed in the width direction Z, in the longitudinal direction Y (specifically, the positive direction indicated by the arrow Y in fig. 14 and 15), so that the parting surface 111b is inclined toward the side of the inner case 1111 away from the connection end. Accordingly, the sound outlet 111a may be provided on the bottom wall 1113. Of course, the sound outlet 111a may be provided at a side of the first side wall 1114 corresponding to the lower side LS, and may be provided at a corner between the first side wall 1114 and the bottom wall 1113.

Further, the cartridge housing 1112 may be provided with an embedded groove 1117 at least partially on the second side wall 1116, and the auxiliary structure 15 is partially embedded in the groove 1117, so that the outer surface of the area of the cartridge housing 1111 not covered by the auxiliary structure 15 continuously transitions with the outer surface of the auxiliary structure 15, which is advantageous for improving the consistency in the appearance of the earphone 10.

As an example, in connection with fig. 14, the deck housing 111 may be provided with a pressure release hole 111c, the pressure release hole 111c allowing the space of the speaker 112 toward the main control circuit board 13 side to communicate with the external environment, i.e., air can freely enter and exit the aforementioned space. In this manner, the diaphragm of speaker 112 is advantageously reduced in resistance during vibration. The pressure relief hole 111c may face the top of the head in the wearing state, so as to avoid that sound waves propagating through the pressure relief hole 111c form a leakage sound (i.e., the second leakage sound) to be heard. Based on the helmholtz resonator, the aperture of the pressure relief hole 111c may be as large as possible, so that the resonance frequency of the second leakage sound is shifted to a frequency band with a higher frequency (e.g., a frequency range greater than 4 kHz) as much as possible, which is advantageous to further avoid that the second leakage sound is heard.

Further, the deck housing 111 may be provided with a sound tuning hole 111d, where the sound tuning hole 111d may shift the resonance frequency of the second leakage sound to a frequency band with a higher frequency (for example, a frequency range greater than 4 kHz) as much as possible, which is advantageous for further avoiding the second leakage sound from being heard. The area of the sound adjusting hole 111d may be smaller than that of the pressure releasing hole 111c, so that the space of the speaker 112 facing the main control circuit board 13 is more communicated with the external environment through the pressure releasing hole 111 c. Further, the distance between the sound outlet 111a and the pressure release hole 111c in the width direction Z is larger than the distance between the sound outlet 111a and the pressure release hole 111d in the width direction Z, so as to avoid the sound waves propagated through the sound outlet 111a and the pressure release hole 111c from being cancelled in the near-field opposite phase, which is beneficial to improving the volume of the sound propagated through the sound outlet 111a heard by the user. Accordingly, the distance between the sound adjusting hole 111d and the sound outlet hole 111a in the length direction Y can be reasonably designed according to actual needs.

As an example, in connection with fig. 14, the sound outlet 111a, the pressure relief hole 111c, and the sound adjustment hole 111d may be provided on the inner core shell 1111, for example, the sound outlet 111a is provided on the bottom wall 1113 and the pressure relief hole 111c and the sound adjustment hole 111d are provided on the first side wall 1114, respectively. Wherein the pressure release hole 111c and the sound adjusting hole 111d may be provided on opposite sides of the first side wall 1114 in the width direction Z, respectively. In this way, since the sound outlet 111a, the pressure relief 111c and the sound adjusting 111d are all disposed on the inner shell 1111, the structure of the outer shell 1112 is simpler, which is beneficial to reducing the processing cost. In addition, since the pressure release hole 111c and the sound adjusting hole 111d are disposed on opposite sides of the first side wall 1114 along the width direction Z, the parting surface 111b can be symmetrically disposed about a reference plane perpendicular to the width direction Z, which is beneficial to improving the appearance quality of the movement module 11.

As an example, in connection with fig. 15, the movement module 11 may include a metal functional pattern such as an antenna pattern 1141 and/or a touch pattern 1142 disposed between the movement case 1112 and the auxiliary structure 15 (e.g., the connection portion 151). Wherein, the antenna pattern 1141 may be formed on the outer side of the core case 1112 by a Laser-Direct-structuring (LDS) technique; the touch pattern 1142 may be formed on the outer side of the core housing 1112 by a laser direct structuring technology, or may be a flexible touch circuit board adhered on the outer side of the core housing 1112. Further, the cartridge case 1112 is provided with metallized holes connected to the antenna pattern 1141 and the touch pattern 1142, respectively. At this time, since the main control circuit board 13 is disposed in the deck housing 111, for example, the main control circuit board 13 is connected to the deck housing 1112, the main control circuit board 13 may be in contact with the inner wall of the corresponding metallized hole through an elastic metal member such as pogo-PIN, metal dome, etc., for example, the antenna pattern 1141 and the touch pattern 1142 are connected to the pogo-PIN131 and the pogo-PIN132, respectively, which are soldered on the main control circuit board 13. Accordingly, speaker 112 is located on a side of main control circuit board 13 facing away from cartridge housing 1112. Thus, compared to the antenna pattern 1141 and the touch pattern 1142 disposed on the inner side of the movement housing 1112 facing the speaker 112, the antenna pattern 1141 disposed on the outer side of the movement housing 1112 can increase the space between the main control circuit board 13 and the movement housing 1112, i.e. increase the antenna clearance area, thereby increasing the interference resistance to the antenna pattern 1141; the touch pattern 1142 is disposed on the outer side of the movement housing 1112, so as to shorten the distance between the touch pattern 1142 and an external signal trigger source (e.g. a finger of a user), that is, reduce the touch distance, thereby increasing the sensitivity of the touch pattern 1142 triggered by the user.

Further, the antenna pattern 1141 may surround the periphery of the touch pattern 1142 to fully utilize the space outside the movement case 1112. The antenna pattern 1141 may be disposed in a U shape, and the touch pattern 1142 may be disposed in a square shape. Accordingly, the antenna pattern 1141 and the touch pattern 1142 and their respective metallized holes may be disposed on the top wall 1115.

As an example, referring to fig. 13, the deck module 11 may include a bracket 115 disposed in the deck housing 111, and the bracket 115 and the speaker 112 may enclose an acoustic cavity 116 such that the acoustic cavity 116 is spaced apart from other structures (e.g., the main control circuit board 13, etc.) in the deck housing 111, which is advantageous for improving the acoustic expressivity of the deck module 11. The cartridge case 111 is provided with an acoustic hole, for example, the acoustic hole is at least one of the pressure relief hole 111c and the sound adjustment hole 111d, and the bracket 115 is provided with an acoustic channel 1151 that communicates the acoustic hole and the acoustic cavity 116, so that the acoustic cavity 116 is in communication with the external environment, that is, air can freely enter and exit the acoustic cavity 116, which is beneficial to reducing the resistance of the diaphragm of the speaker 112 in the vibration process.

Further, the bracket 115 and the cartridge case 111 cooperate to form a first glue groove 1171 surrounding at least a portion of the acoustic hole, where the first glue groove 1171 accommodates a first glue for sealing an assembly gap between the bracket 115 and the cartridge case 111, that is, the first glue is used for performing waterproof sealing, so that it is beneficial to avoid external sweat, rainwater, and other droplets from entering a space where the main control circuit board 13 in the cartridge case 111 is located. Therefore, based on the helmholtz resonator, compared with the related art that a silicone sleeve is pressed on the movement housing 111 by the bracket 115 to perform waterproof sealing, the present disclosure omits the silicone sleeve in the related art by performing waterproof sealing with the first glue, which is beneficial to shortening the length of the communication portion (including the acoustic channel 1151 and the acoustic hole) between the acoustic cavity 116 and the external environment, so that the resonant frequency of the leakage sound (i.e., the second leakage sound) formed by propagating out through the pressure release hole 111c is offset toward the frequency band with higher frequency (e.g., the frequency range greater than 4 kHz), thereby further avoiding the second leakage sound from being heard.

It should be noted that: when the acoustic hole is the pressure relief hole 111c, the first glue groove 1171 surrounds at least a portion of the pressure relief hole 111 c; when the acoustic hole is the sound adjusting hole 111d, the first glue groove 1171 surrounds at least a portion of the sound adjusting hole 111 d; when the acoustic holes are the pressure relief hole 111c and the sound adjusting hole 111d, the first glue groove 1171 surrounds at least a portion of the pressure relief hole 111c and the sound adjusting hole 111d, respectively. For convenience of description, and referring to fig. 14, the above-mentioned acoustic holes are taken as the pressure relief hole 111c and the sound adjusting hole 111d, and the first glue groove 1171 surrounds at least a portion of the pressure relief hole 111c and the sound adjusting hole 111d, respectively, for example. Further, if the gap between the bracket 115 and the cartridge housing 111 (e.g., the bottom wall 1113 thereof) is sufficiently large, or the bottom wall 1113 and the first side wall 1114 in the cartridge housing 111 are not integrally formed members (i.e., two separate members), the first adhesive groove 1171 may surround all of the above-mentioned acoustic holes, i.e., the first adhesive groove 1171 is a complete annular structure.

As an example, referring to fig. 16 and 13, the bracket 115 may include an annular body portion 1152 and a docking portion 1153 connected to the annular body portion 1152. Wherein, annular body 1152 is disposed around speaker 112 to form acoustic chamber 116, and acoustic channel 1151 extends through interface 1153 and annular body 1152. Further, a docking portion 1153 is located between the annular body portion 1152 and the cartridge case 111, and surrounds at least a portion of the acoustic hole, and the docking portion 1153 cooperates with the cartridge case 111 to form a first adhesive receiving recess 1171. Wherein, since the acoustic holes may be the pressure release hole 111c and the sound adjustment hole 111d, two docking portions 1153 are correspondingly provided, and two first glue accommodating grooves 1171 are correspondingly provided. Accordingly, the docking portion 1153 cooperates with the first side wall 1114 to form a first glue recess 1171. In this way, the support 115 is disposed in a ring shape, so that the speaker 112 is exposed toward the side of the main control circuit board 13, which is beneficial to reducing the thickness of the movement module 11 in the thickness direction X.

As an example, referring to fig. 17 and 14, the inner side of the cartridge case 111 may be provided with a depression 1119, the acoustic hole may be provided at the bottom of the depression 1119, and the cartridge module 11 may include an acoustic resistive mesh 118 provided in the depression 1119, and the docking portion 1153 may press the acoustic resistive mesh 118 against the bottom of the depression 1119. In this way, it is advantageous not only to avoid the holder 115 from scraping to the acoustic resistive mesh 118 during assembly, but also to reduce the assembly gap between the holder 115, the acoustic resistive mesh 118, and the inner case 1111, and to avoid rattling of the acoustic resistive mesh 118. Wherein, the acoustic resistance net 118 can be pre-fixed at the bottom of the concave area 1119 through double faced adhesive tape or glue; the acoustic resistive mesh 118 may be pre-fixed to the protective steel mesh 119, and the protective steel mesh 119 is pre-fixed to the bottom of the recess 1119 by double faced adhesive tape or glue. Accordingly, since the above-mentioned acoustic holes may be the pressure relief hole 111c and the sound adjusting hole 111d, the concave area 1119 is correspondingly provided with two, and the acoustic resistive mesh 118 is correspondingly provided with two.

Further, the first glue may further be used to seal the assembly gap between the support 115 and the acoustically resistive mesh 118 and/or the assembly gap between the acoustically resistive mesh 118 and the cartridge housing 111 (e.g., the side wall of the recess 1119), which may facilitate a further watertight seal.

As an example, in conjunction with fig. 13, 14, and 16, the docking portion 1153 may be used to form a bottom wall and one side groove wall of the first glue groove 1171, and the cartridge housing 111 may be used to form the other side groove wall of the first glue groove 1171. The groove wall on the cartridge housing 111 is opposite to the groove wall on the docking portion 1153, so that the first glue groove 1171 has a certain width and depth. Of course, the docking portion 1153 may be used to form one side groove wall of the first glue groove 1171, and the cartridge housing 111 may be used to form the bottom wall and the other side groove wall of the first glue groove 1171; alternatively, interface 1153 may be used to form one portion of the side walls and bottom wall of first glue well 1171 and cartridge housing 111 may be used to form another portion of the other side walls and bottom wall of first glue well 1171.

As an example, referring to fig. 17 to 25, the speaker 112 may include a frame 1121 and a magnetically conductive cover 1122 connected to the frame 1121, the lower end of the bracket 115 may be supported on the frame 1121, the acoustic channel 1151 may be provided in an open state on a side facing the frame 1121, and the frame 1121 may further block an open portion of the acoustic channel 1151. At this time, it may be simply considered that the first glue well 1171 surrounds a portion of the acoustic hole, so that glue may be filled in the first glue well 1171 in a subsequent manner such as a dispensing process.

Further, the speaker 112 may include a diaphragm 1123 and a hinge 1124, the hinge 1124 connecting the diaphragm 1123 and the frame 1121. Wherein, after the speaker 112 is assembled in the movement case 111, the diaphragm 1123 and the ring 1124 and the surrounding frame 1121 and the movement case 111 can block the droplets of sweat, rainwater, etc. which invade through the sound outlet 111a from further invading the space of the main control circuit board 13 in the movement case 111. Based on this, the speaker 112 may include a magnet 1125 disposed in the magnetic shield 1122 and a coil 1126 connected to the diaphragm 1123, the magnet 1125 and the magnetic shield 1122 forming a magnetic gap into which the coil 1126 extends. Wherein, the speaker 112 may include a magnetic conductive plate 1127 disposed at a side of the magnet 1125 facing the diaphragm 1123, the magnetic conductive plate 1127, the magnetic conductive cover 1122, and the coil 1126 are overlapped in a vibration direction (e.g., a thickness direction X, which will not be described further below) of the speaker 112, so that a magnetic induction line of a magnetic field generated by the magnet 1125 passes through the coil 1126 more.

In some embodiments, the basin holder 1121 may include a first annular mesa 11211 and a second annular mesa 11212 disposed in a stepped configuration, the second annular mesa 11212 being disposed around the periphery of the first annular mesa 11211; a portion of the lower end of the bracket 115 may be supported on the first annular table 11211, and another portion of the lower end of the bracket 115 may form a spaced area with the second annular table 11212, such that the bracket 115, the tub frame 1121, and the cartridge housing 111 cooperate to form a second glue well 1172, and the second glue well 1172 accommodates a second glue for sealing an assembly gap between any two of the bracket 115, the tub frame 1121, and the cartridge housing 111 for a corresponding waterproof seal.

In some embodiments, the upper end of the support 115 may be erected on the basin frame 1121, and form a third glue groove 1173 in cooperation with the basin frame 1121 and the magnetic conductive cover 1122, where the third glue groove 1173 accommodates a third glue for sealing an assembly gap between the support 115 and the basin frame 1121 and the magnetic conductive cover 1122, so as to perform a corresponding waterproof seal.

It should be noted that: in a specific assembly process of the movement module 11, the method may include the following process steps, and the sequence of all the process steps may be adjusted as required: 1) The acoustic resistive mesh 118 and the protective steel mesh 119 are pre-fixed at the bottom of the recessed area 1119 by double faced adhesive tape; 2) Fixing the speaker 112 to the bottom wall 1113, dispensing the assembly gap therebetween, and accumulating corresponding glue portions on the second annular mesa 11212 of the speaker 112; 3) Before the glue in step 2) is cured, fixing the bracket 115 on the speaker 112, wherein the lower end of the bracket 115 is supported on the first annular table 11211 of the speaker 112, so that the space between the lower end of the bracket 115 and the second annular table 11212 is filled with glue, the abutting portion 1153 of the bracket 115 presses the acoustic resistive mesh 118 and cooperates with the first side wall 1114 to form a first glue containing groove 1171, and the upper end of the bracket 115 is erected on the basin frame 1121 and cooperates with the basin frame 1121 and the magnetic conductive cover 1122 to form a third glue containing groove 1173; 4) Dispensing is performed to the assembly gaps between the first adhesive accommodating groove 1171, the third adhesive accommodating groove 1173 and the lower end of the bracket 115 and the speaker 112 and the inner core shell 1111. Wherein, since the assembly gap between the lower end of the bracket 115 and the speaker 112 and the inner chassis 1111 is very close to the first adhesive groove 1171, the assembly gap between the lower end of the bracket 115 and the speaker 112 and the inner chassis 1111 can be simply regarded as a continuation of the first adhesive groove 1171, that is, the first adhesive groove 1171 and the second adhesive groove 1172 can communicate.

Based on the above detailed description, the waterproof performance of the earphone 10 at the assembly position of the bracket 115 and the cartridge case 111 can be improved through the first glue (and the second glue) or the silicone sleeve, so that the space of the main control circuit board 13 in the cartridge case 111 has a higher waterproof level. Based on this, the inside of the speaker 112 may be provided with a first accommodation space communicating with the acoustic chamber 116, and the speaker 112, the bracket 115, and the deck case 111 may be further fitted outside the speaker 112 to form a second accommodation space not communicating with the acoustic chamber 116. Wherein, the first accommodating space can be formed by matching the basin frame 1121, the magnetic conductive cover 1122, the vibrating diaphragm 1123 and the folded ring 1124, so that the structures of the magnet 1125, the coil 1126, the magnetic conductive plate 1127 and the like can be arranged in the first accommodating space; the main control circuit board 13 and other structures may be disposed in the second accommodating space. In other words, for the speaker 112, the first accommodating space and the second accommodating space may be two spaces having a certain volume inside and outside the speaker 112, respectively. Notably, are: the first receiving space may be in communication with the acoustic chamber 116 through a through hole 11213 formed in the basin frame 1121. In the embodiment where the acoustic hole is the pressure relief hole 111c (or the sound adjustment hole 111 d), the through hole 11213 may be disposed on one side of the basin frame 1121 near the pressure relief hole 111c (or the sound adjustment hole 111 d); in the embodiment where the acoustic holes are the pressure relief hole 111c and the sound adjusting hole 111d, two groups of through holes 11213 may be provided, wherein one group of through holes 11213 may be provided on one side of the basin frame 1121 near the pressure relief hole 111c, and the other group of through holes 11213 may be provided on the other side of the basin frame 1121 near the sound adjusting hole 111 d.

As an example, referring to fig. 23 and 25, the speaker 112 may include metal pieces 1128 provided on the tub 1121, and the number of the metal pieces 1128 may be two, wherein one metal piece 1128 serves as a positive terminal of the speaker 112 and the other metal piece 1128 serves as a negative terminal of the speaker 112. Wherein each metal piece 1128 may include a first pad 11281 and a second pad 11282, respectively, and a transition portion 11283 connecting the first pad 11281 and the second pad 11282, and the first pad 11281 and the second pad 11282 may be exposed from the tub 1121. At this time, the first pads 11281 may be positioned in the first receiving space and connected to the coil 1126, and the second pads 11282 may be positioned in the second receiving space so that the coil 1126 is connected to the main control circuit board 13 through the metal member 1128. Wherein the spacing between the first pads 11281 of the two metal pieces 1128 may be greater than the spacing between the second pads 11282 of the two metal pieces 1128. In this way, on the one hand, although the first bonding pad 11281 is disposed in the first accommodating space with a low waterproof level, the first bonding pads 11281 of the two metal pieces 1128 are spaced relatively much, so that droplets of sweat, rainwater, etc. that invade the first accommodating space via the acoustic holes (for example, the pressure release hole 111c or the sound adjustment hole 111 d) and the acoustic channel 1151 are not likely to cause shorting of the first bonding pads 11281 of the two metal pieces 1128, thereby avoiding burning out of the earphone 10; on the other hand, since the second pads 11282 are disposed in the above-mentioned second receiving space having a higher waterproof level, the space between the second pads 11282 of the two metal pieces 1128 is not shorted even if it is small, thereby avoiding the earphone 10 from being burned out. In addition, since the space between the second pads 11282 of the two metal pieces 1128 is smaller, the wires or flexible circuit board connecting the two metal pieces 1128 and the main control circuit board 13 is shortened, thereby simplifying the wiring structure of the speaker 112 and reducing the cost.

As an example, referring to fig. 23, the tub 1121 may have a long axis direction (e.g., a length direction Y) and a short axis direction (e.g., a width direction Z) perpendicular to a vibration direction of the speaker 112 and orthogonal to each other. The dimension of the frame 1121 in the long axis direction may be larger than the dimension of the frame 1121 in the short axis direction, for example, the length-width relationship of the frame 1121 matches the length-width relationship of the movement module 11. At this time, the two metal pieces 1128 may be located at the same end in the long axis direction to simplify the wiring of the earphone 10. Accordingly, two metal pieces 1128 may be located between two sets of through holes 11213 in the width direction.

In some embodiments, the transition 11283 may be embedded within the frame 1121, for example, the metal piece 1128 may be injection molded with the frame 1121 by a metal insert process. In this way, since the transition portion 11283 is not exposed from the frame 1121, the space between the transition portions 11283 of the two metal pieces 1128 is not shorted even if smaller, so that the earphone 10 is prevented from being burned out.

In some embodiments, the transition 11283 may be sealed to the frame 1121 with a water-tight seal, such as by securing the metal piece 1128 to the frame 1121 and then covering the transition 11283 with glue. In this way, even though the interval between the transition portions 11283 of the two metal pieces 1128 is small, the transition portions 11283 are waterproof-sealed on the frame 1121 so that the transition portions 11283 of the two metal pieces 1128 are not shorted, thereby preventing the earphone 10 from being burned out.

As an example, in connection with fig. 25, the second pads 11282 of the two metal pieces 1128 may be disposed side by side and at a distance, one end of each transition portion 11283 may be connected with the corresponding second pad 11282, the two transition portions 11283 may extend in a direction away from each other, and each first pad 11281 may be connected with the other end of the corresponding transition portion 11283, respectively, such that a space between the first pads 11281 of the two metal pieces 1128 is greater than a space between the second pads 11282 of the two metal pieces 1128. Wherein, the bending degree of the transition portion 11283 can be consistent with the variation trend of the region of the basin frame 1121 where the metal member 1128 is disposed.

As an example, referring to fig. 25, the basin holder 1121 may include an annular peripheral wall 11214 and an annular flange 11215 connected to an inner wall surface of the annular peripheral wall 11214, and a boss 11216 provided at a connection of the annular flange 11215 and the annular peripheral wall 11214. Wherein, the magnetic conductive cover 1122 can be fixed on the annular flange 11215 so that the magnetic conductive cover 1122 can be connected with the basin frame 1121; the boss 11216 is used to support the metal pieces 1128 such that the transition portion 11283 may be hidden within the boss 11216 and the second bonding pad 11282 may be exposed from the boss 11216 to facilitate connection of the coil 1126 to the metal pieces 1128 and to avoid shorting of the transition portions 11283 of the two metal pieces 1128.

As an example, in connection with fig. 23 and 25, the bosses 11216 may be provided at intervals in the circumferential direction of the annular peripheral wall 11214, for example, originally one boss 11216 is split at the center thereof to be divided into two. At this time, each boss 11216 may support one metal piece 1128, respectively, i.e., the transition portions 11283 of two metal pieces 1128 may be hidden within the bosses 11216, respectively. In this way, even if droplets of sweat, rainwater, or the like accumulate at one of the bosses 11216 and the second pad 11282 exposed thereon, the droplets hardly flow to the other boss 11216 and the second pad 11282 exposed thereon, which is advantageous in avoiding shorting of the second pads 11282 of the two metal pieces 1128.

As an example, in connection with fig. 19 and 23, the coil 1126 may include an annular body 11261 and a lead 11262 connected to the annular body 11261. Wherein the annular body 11261 and the lead 11262 may be the same wire. Based on this, the above-mentioned wire is wound by a certain number of turns according to actual demands to obtain an annular body 11261, and the annular body 11261 may be connected to the diaphragm 1123; the leads 11262 may be two ends of the aforementioned wire, that is, the number of the leads 11262 may be two, and the two leads 11262 may be connected to the second pads 11282 of the two metal pieces 1128 one by one, respectively. Further, the annular body 11261 may be located inside the basin 1121, for example, extending into the magnetic gap formed by the magnets 1125 and the magnetically permeable cover 1122. Wherein, the lead 11262 moves relative to the frame 1121 following the annular body 11261 after the excitation signal is input from the speaker 112, and the annular body 11261 pushes the diaphragm 1123 to generate sound waves.

As an example, referring to fig. 23, the frame 1121 may be provided with a relief groove 11217, and an orthographic projection of the lead 11262 in a vibration direction of the speaker 112 may at least partially fall within the relief groove 11217. Wherein, the depth of the avoidance groove 11217 may be greater than 0 and equal to or less than 0.2mm. In this way, the distance between the lead 11262 and the frame 1121 can be increased to a certain extent by avoiding the groove 11217, so as to reduce the risk of collision between the lead 11262 and the frame 1121, especially when the speaker 112 works with small amplitude, and reduce the stroke after the lead 11262 collides with the frame 1121, especially when the speaker 112 works with large amplitude, which is beneficial to improving the reliability of the speaker 112.

In some embodiments, the distance between the lead 11262 and the bottom of the avoidance groove 11217 may be greater than the maximum amplitude of movement of the lead 11262 relative to the basin frame 1121 in the direction of vibration of the speaker 112 when no excitation signal is input to the speaker 112, to further reduce the risk of collision of the lead 11262 with the basin frame 1121 and to reduce the travel after collision of the lead 11262 with the basin frame 1121.

In some embodiments, the relief groove 11217 may be located near an end of the lead 11262 where the lead 11262 is connected to the annular body 11261, that is, the relief groove 11217 may be correspondingly disposed at a position where the amount of movement of the lead 11262 following the movement of the annular body 11261 is relatively large, that is, a position where the risk of the lead 11262 colliding with the frame 1121 is relatively high, so as to further reduce the risk of the lead 11262 colliding with the frame 1121 and reduce the stroke of the lead 11262 after colliding with the frame 1121.

As an example, referring to fig. 23, the lead 11262 may include a first extension 11263 connected with the ring-shaped body 11261 and a second extension 11264 bent with respect to the first extension 11263, and an orthographic projection of the first extension 11263 in a vibration direction of the speaker 112 may at least partially fall within the escape recess 11217 to reduce a risk of the lead 11262 colliding with the tub frame 1121 and to reduce a stroke after the lead 11262 collides with the tub frame 1121. Wherein, at least a portion of the second extension 11264 near the first extension 11263 in the orthographic projection of the speaker 112 along the vibration direction may fall into the avoidance groove 11217 to further reduce the risk of the wire 11262 colliding with the tub frame 1121 and to reduce the stroke after the wire 11262 collides with the tub frame 1121. Accordingly, an end of the second extension 11264 remote from the first extension 11263 may be connected with the second pad 11282 (an extension direction of the lead). Of course, in other embodiments, the leads 11262 may be generally linear or arcuate in configuration.

In some embodiments, the ratio between the length of the second extension 11264 and the length of the first extension 11263 may be between 2 and 15. Wherein, if the aforementioned ratio is too small, the amplitude of the end of the second extension 11264 away from the first extension 11263 is still large, which easily causes the second extension 11264 to be broken or to be unwelded at the second pad 11282; if the aforementioned ratio is too large, it is liable to cause the dead weight of the second extension 11264 to be too large to excessively pull the first extension 11263, and also liable to cause the overall size of the speaker 112 to be large, which is disadvantageous in downsizing the product. Further, the second extension 11264 may be spaced apart from the annular body 11261 in a direction perpendicular to the vibration direction of the speaker 112 (e.g., the width direction Z) by between 1.1mm and 2.1 mm. Wherein if the foregoing pitch is too small, the amplitude of the second extension 11264 is easily caused to remain large, thereby easily causing the second extension 11264 to collide with the frame 1121, and the second extension 11264 to be broken or to be unwelded at the second pad 11282; if the aforementioned ratio is too large, the first extension 11263 is easily deformed excessively toward the tub 1121 due to excessive self weight, so that collision with the tub 1121 is easily caused, and the overall size of the speaker 112 is easily increased, which is disadvantageous in product miniaturization.

In some embodiments, such as fig. 23, the angle between the second extension 11264 and the first extension 11263 may be an obtuse angle, which may be advantageous in reducing stress between the second extension 11264 and the first extension 11263, thereby increasing the reliability of the lead 11262.

In some embodiments, such as fig. 24, at least a portion of the spacing of the second extension 11264 from the tub frame 1121 in the vibration direction of the speaker 112 may be gradually reduced in the extension direction away from the first extension 11263 (e.g., the opposite direction of arrow Y) such that the portion of the second extension 11264 near the first extension 11263 and the first extension 11263 are as far away from the tub frame 1121 as possible in the vibration direction of the speaker 112, thereby reducing the risk of the lead 11262 colliding with the tub frame 1121 and reducing the stroke after the lead 11262 collides with the tub frame 1121.

In some embodiments, the frame 1121 may be provided with a plurality of through holes 11213 spaced around the annular body 11261, the avoidance groove 11217 may be in communication with the through holes 11213 to simplify the structure of the frame 1121, and the orthographic projection of the second extension 11264 along the vibration direction of the speaker 112 may at least partially fall into the through holes 11213 to reduce the area where the second extension 11264 may collide with the frame 1121, thereby increasing the reliability of the speaker 112. Wherein the plurality of through holes 11213 can be divided into two groups, and orthographic projections of the second extension 11264 of the two leads 11262 along the vibration direction of the speaker 112 can be respectively at least partially within the through holes 11213. Based on this, each set of through holes 11213 can in turn comprise a plurality of mutually spaced through holes 11213, for example four as shown in fig. 23; of course each set of through holes 11213 may also include only one relatively large through hole 11213.

As an example, referring to fig. 23 and 25, the frame 1121 may be provided with pads connected to the leads 11262, and the number of the pads may be two, one of which serves as a positive terminal of the speaker 112 and the other of which serves as a negative terminal of the speaker 112. The bonding pads may be the metal pieces 1128 mentioned above, or other arrangements known to those skilled in the art, and will not be described in detail. Further, the leads 11262 have a first end 1126a proximate the annular body 11261 and a second end 1126b distal from the annular body 11261, the second end 1126b may be secured to a corresponding pad, such as an end of the leads 11262 distal from the annular body 11261 being soldered to the first pad 11281. Wherein the ratio between the length of the lead 11262 and the maximum amplitude of the movement of the coil 1126 relative to the basin frame 1121 may be between 8 and 75. Wherein if the aforementioned ratio is too small, the amplitude of the second end 1126b tends to remain large, thereby easily causing the wire 11262 to be broken or to be unwelded at the aforementioned pad; if the above ratio is too large, the leads 11262 are liable to be excessively deformed toward the tub 1121 by excessive self weight, so that collision with the tub 1121 is liable to occur, and the overall size of the speaker 112 is liable to be large, which is disadvantageous in downsizing of the product. In short, the present solution is advantageous in improving the technical problem of stress concentration of the leads 11262.

In some embodiments, the ratio between the wire diameter of the lead 11262 and the length of the lead 11262 may be between 50 and 1000. Wherein, if the aforementioned ratio is too small, breakage of the lead 11262 due to too small rigidity is liable to occur; if the aforementioned ratio is too large, the lead 11262 is easily deformed excessively toward the tub 1121 due to excessive self-weight, and thus is easily collided with the tub 1121.

In some embodiments, the lead 11262 may be further secured to the frame 1121 at a fixed location 1126c between the first and second ends 1126a, 1126b, such that vibrations of the lead 11262 following the annular body 11261 are difficult to transfer to the bond pad, which advantageously prevents the lead 11262 from resonating near one end of the bond pad or shifting the peak frequency of the resonance to a higher frequency band (e.g., above 10 kHz), thereby reducing the risk of wire breakage of the lead 11262 or de-bonding at the bond pad. The portion of the lead 11262 between the first end 1126a and the fixed position 1126c may be suspended relative to the frame 1121, and the portion of the lead 11262 between the second end 1126b and the fixed position 1126c may also be suspended relative to the frame 1121, so as to reduce the risk of collision between the lead 11262 and the frame 1121.

As an example, referring to fig. 19 and 23, a support block 11218 may be provided on the tub frame 1121, and the support block 11218 is located between the first end 1126a and the second end 1126b and may correspond to the fixed position 1126c. At this time, the lead 11262 may be fixed on the support block 11218 at a fixing position 1126c such that at least a portion of the lead 11262 is suspended with respect to the tub 1121. In this way, since the supporting block 11218 is a part of the structure of the basin frame 1121, the fixing position 1126c is more accurate, which is beneficial to avoiding workers from fixing a certain position on the lead 11262 on the basin frame 1121 at will, thereby being beneficial to improving the product consistency of the loudspeaker 112 in mass production and further improving the yield.

It should be noted that: in the embodiment in which the tub 1121 is provided with a plurality of through holes 11213 spaced around the annular body 11261, the supporting block 11218 may be positioned between two adjacent through holes 11213, which is simple and reliable. In addition, the supporting blocks 11218 may also serve as reinforcing ribs of the frame 1121 to increase the structural strength of the frame 1121. Further, for the lead 11262 corresponding to the positive terminal or the negative terminal of the speaker 112, the fixed position 1126c and the corresponding support block 11218 may be provided in plural, for example, two or three, or the like.

In some embodiments, the leads 11262 may be secured to the support block 11218 by glue 11219, which may be elastic after curing of the glue 11219, such as a soft gel like silicone. In this manner, it is beneficial to absorb the vibration of the lead 11262 following the annular body 11261, reducing the stress of the lead 11262 at the fixed location 1126c, thereby reducing the risk of the lead 11262 breaking. Of course, in an application scenario with a low risk of wire breakage, the glue 11219 may be hard glue.

In some embodiments, the side of the support block 11218 that contacts the leads 11262 may be provided with a limit groove. Thus, the consistency of the relative positions of the supporting blocks 11218 and the leads 11262 is improved in mass production, and the yield of products is improved. Notably, are: in embodiments where the leads 11262 are secured to the support block 11218 by glue 11219, the relief grooves may also double as glue pockets to facilitate the accumulation of sufficient glue 11219 on the support block 11218 to secure the leads 11262.

In some embodiments, the first length of the lead 11262 between the first end 1126a and the support block 11218 may be greater than the second length of the lead 11262 between the second end 1126b and the support block 11218. In this way, the risk of breakage of the lead 11262 due to the first length being too small is reduced with the total length of the lead 11262 unchanged. As an example, the ratio between the aforementioned first length and the aforementioned second length may be between 1 and 12. If the aforementioned ratio is too small, however, the amplitude of the lead 11262 at the support block 11218 is still large, which tends to cause the lead 11262 to be broken.

In some embodiments, the first end 1126a and the fixed position 1126c of the lead 11262 supported by the support block 11218 are on the same reference plane perpendicular to the vibration direction of the speaker 112 when no excitation signal is input to the speaker 112. In this manner, stresses within the leads 11262 are advantageously reduced, thereby reducing the risk of breakage of the leads 11262.

As an example, in connection with fig. 23, the second extension 11264 may be fixed to the support block 11218 and the pad, for example, the second extension 11264 may be welded to the pad at the second end 1126b and fixed to the support block 11218 by glue 11219 at the fixing location 1126 c. Wherein, with the end of the second extension portion 11264 connected to the first extension portion 11263 as the start point of the second extension portion 11264 and the second end 1126b as the end point of the second extension portion 11264, the position (e.g., the fixing position 1126 c) where the second extension portion 11264 is fixed to the support block 11218 may be located between one half of the length of the second extension portion 11264 and three quarters of the length of the second extension portion 11264.

As an example, referring to fig. 19, 21, and 22, the diaphragm 1123 may include a body portion 11231, a first annular connecting portion 11232, and a second annular connecting portion 11233 integrally connected, the first annular connecting portion 11232 being connected to the coil 1126, and the second annular connecting portion 11233 being connected to the turn-down ring 1124. Wherein the body portion 11231 may be provided in a dome-shaped structure protruding in a direction away from the coil 1126. Further, the front projection of the second annular connecting portion 11233 in the vibration direction of the speaker 112 may cover the lead 11262, and the second annular connecting portion 11233 is bent toward a side away from the coil 1126 with respect to the first annular connecting portion 11232 so as to have a distance from the lead 11262 in the vibration direction of the speaker 112, which is advantageous in avoiding unnecessary collision of the lead 11262 with the folder 1124 or the diaphragm 1123 connected thereto.

As an example, in connection with fig. 19 to 22, the hinge 1124 may include a third annular connecting portion 11241, a fold portion 11242, and a fourth annular connecting portion 11243 that are integrally connected. Wherein the third annular connecting portion 11241 may be connected to a side of the second annular connecting portion 11233 facing away from the coil 1126, and the fourth annular connecting portion 11243 may be connected to the frame 1121 (e.g., the annular peripheral wall 11214) through a reinforcing member 11244. Further, the pleat 11242 may be convex in a direction away from the lead 11262, which may be advantageous to avoid unnecessary collisions between the two.

Based on the above related description, the present application provides an electronic device, which may include a support assembly and a movement module 11, where the support assembly may be connected with the movement housing 111 to support the movement module 11 to be worn in a wearing position. The support assembly may be configured to be hung from an ear (e.g., hook-like structure 12) when worn, or may be configured to bypass a crown of the head when worn. Further, the wearing position may be a position where the cheek of the user approaches the ear, a position on the front side of the ear, or other physiological parts of the user. In this regard, the electronic device may be a terminal device such as a smart glasses including the deck module 11, in addition to the earphone 10. The deck module 11 may include a speaker 112, and may also include a transducer device based on bone conduction principles.
