[0035] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0036] Reference to "embodiment" in this application means that a specific feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0037] Combination Figure 1 The ear 100 of the user may include an external auditory canal 101, a cavum conchae 102, a cymba conchae 103, a triangular fossa 104, an antihelix 105, a scaphoid 106, an auricle 107, an antitragus 108 and other physiological parts. Among them, although the external auditory canal 101 has a certain depth and extends to the eardrum, for the convenience of description, and in combination with Figure 1 In the present application, unless otherwise specified, the external auditory canal 101 specifically refers to its entrance away from the tympanic membrane (i.e., the ear hole). Furthermore, the concha cavity 102, the hymena conchae 103, the triangular fossa 104 and other physiological parts have a certain volume and depth; and the concha cavity 102 is directly connected to the external auditory canal 101, which can be simply regarded as the aforementioned ear hole being located at the bottom of the concha cavity 102.

[0038] Furthermore, different users may have individual differences, resulting in different shapes, sizes, and other dimensional differences in the ears. For ease of description, and to reduce (or even eliminate) individual differences between different users, a simulator containing a head and its (left and right) ears can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BC KEMAR, HEAD Acoustics, B&K 4128 series, or B&K 5128 series, to present the scenario of most users wearing the headphones 10. Taking GRAS KEMAR as an example, the ear simulator can be any one of GRAS 45AC, GRAS 45BC, GRAS 45CC, or GRAS 43AG, etc.; taking HEAD Acoustics as an example, the ear simulator can be any one of HMS II.3, HMS II.3LN, or HMS II.3LN HEC, etc. Therefore, in the present application, descriptions such as "the user wears the earphone 10", "the earphone 10 is in a wearing state", and "in a wearing state" may refer to the earphone 10 described in the present application being worn on the ear of the aforementioned simulator. Of course, precisely because of individual differences among different users, there may be certain differences between the earphone 10 worn by different users and the earphone 10 worn on the ear of the aforementioned simulator, but such differences should be tolerated.

[0039] It should be noted that in the fields of medicine and anatomy, three basic planes of the human body can be defined: the sagittal plane, the coronal plane, and the horizontal plane, as well as three basic axes: the sagittal axis, the coronal axis, and the vertical axis. Among them, the sagittal plane refers to a plane perpendicular to the ground along the front-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a plane perpendicular to the ground along the left-right direction of the body, which divides the human body into front and back parts; the horizontal plane refers to a plane parallel to the ground along the up-down direction of the body, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis refers to an axis along the front-back direction of the body and perpendicular to the coronal plane, the coronal axis refers to an axis along the left-right direction of the body and perpendicular to the sagittal plane, and the vertical axis refers to an axis along the up-down direction of the body and perpendicular to the horizontal plane. Furthermore, the "front side of the ear" mentioned in this application is a concept relative to the "back side of the ear". The former refers to the side of the ear away from the head, and the latter refers to the side of the ear facing the head. They are both for the user's ear. Among them, when observing the ear of the above simulator along the direction of the human coronal axis, it can be obtained Figure 1 Schematic diagram of the front profile of the ear shown.

[0040] As an example, in combination Figures 2 to 6 The earphone 10 may include a movement module 11 and an ear hook portion 12 connected to the movement module 11, the movement module 11 is located on the front side of the ear in the wearing state, and at least part of the ear hook portion 12 is located on the back side of the ear in the wearing state, so that the earphone 10 is hung on the ear in the wearing state. The movement module 11 may have a connecting end CE connected to the ear hook portion 12 and a free end FE not connected to the ear hook portion 12. Further, the movement module 11 may be configured not to block the external auditory canal in the wearing state, so that the earphone 10 acts as an "open earphone". Due to individual differences among different users, when the earphone 10 is worn by different users, the movement module 11 may partially block the external auditory canal, but the external auditory canal is still not blocked.

[0041] Optionally, in some embodiments, the movement module 11 includes a housing assembly 110 (in some embodiments of the present application, the housing assembly is also referred to as a movement housing), a speaker 111 and a circuit board 112. Further, the speaker 111 and the circuit board 112 can be arranged in a stacked manner in the housing assembly 110, and such an arrangement can effectively improve the space utilization inside the movement module 11, and at the same time facilitate the optimization of the overall size of the earphone 10. Specifically, without changing the size of the movement module 11, the stacked arrangement can make the circuit board 112 as large and complete as possible without the interference of the speaker 111, which is convenient for processing, and also effectively improves the board area of ​​the circuit board 112, and further enables the circuit board 112 to integrate more circuits, such as a main control circuit, a sensor control circuit and other circuits. In some embodiments, the circuit board 112 is integrated with any one or more circuits of the main control circuit, the sensor control circuit and other circuits. Preferably, in this embodiment, at least the main control circuit of the earphone 10 and the sensor control circuit for connecting to the sensor 15 are integrated on the circuit board 112. The speaker 111 is a component that can convert an electrical signal into a corresponding sound signal under the control of the circuit board 112. In this embodiment, the speaker 111 is an air conduction speaker 111. In other embodiments, the speaker 111 can also be set as a bone conduction speaker 111.

[0042] It should be noted that the speaker 111 and the circuit board 112 are disposed in a stacked manner in the housing assembly 110 , which means that along the axial direction z1 of the speaker 111 , the speaker 111 and the circuit board 112 are arranged up and down in space.

[0043] Optionally, in some embodiments, the earphone 10 further includes a battery assembly connected to one end of the ear hook portion 12 away from the movement module 11, the battery assembly includes a battery housing 13, a battery coupled to the movement module 11 is disposed in the battery housing 13, and the orthographic projection of the battery housing 13 on the reference plane partially overlaps with the orthographic projection of the free end FE on the same reference plane. In this way, when the free end FE is at least partially inserted into the concha cavity, the battery housing 13 can support the ear from the back side of the ear, which is conducive to improving the stability of the earphone 10 when worn.

[0044] Alternatively, if Figure 4-6 As shown, in some embodiments, the earphone 10 also includes a shell assembly 110, a deformable member 14 and a sensor 15 arranged on the deformable member 14, wherein the deformable member 14 is provided with a bending area that can bend laterally when subjected to an opposite extrusion force F1 applied along the spacing direction, and the sensor 15 is arranged in the bending area to generate a corresponding electrical signal when the bending degree of the bending area is greater than a preset bending threshold, and transmit the corresponding electrical signal to the corresponding component of the earphone 10, such as the circuit board 112, so that the circuit board 112 performs a corresponding control function based on the corresponding electrical signal, thereby controlling the earphone 10 to perform the corresponding earphone 10 functions, for example, switching tracks, pausing playback, starting playback, and other earphone 10 functions.

[0045] It should be noted that the bending area is a part of the deformable member 14, and the bending area is an area on the deformable member 14 that can undergo lateral bending deformation when subjected to the opposite extrusion force F1 and the bending amount is larger than other parts of the deformable member 14. In a natural state, the bending area can be any structural shape.

[0046] Optionally, in some embodiments, a preset bending threshold value can be set, and the electrical signal generated by the sensor 15 when the bending degree of the bending area is greater than the preset bending threshold value is used as the electrical signal to trigger the headphone function, so that the circuit board 112 can better avoid the electrical signal generated by the user's accidental touch, thereby effectively improving the control accuracy of the headphone 10 and the anti-interference ability of the control function. For example, in some embodiments, the sensor 15 generates an electrical signal of a corresponding level based on the deformation size of the deformable member 14, and the circuit board 112 does not perform the control function when the signal level of the electrical signal does not exceed the preset threshold value (when the signal level is less than or equal to the preset threshold value, it indicates that the electrical signal is a signal caused by an accidental touch operation). Specifically, the preset bending threshold value can be determined by a statistical analysis method, or it can be determined by the user based on usage habits.

[0047] Furthermore, if Figure 4-6As shown, in some embodiments, the shell assembly 110 includes a first shell 1101, and the first shell 1101 includes a first side wall portion US1 and a second side wall portion LS1 that are spaced relative to each other, wherein an opposite extrusion force F1 applied to the outer sides of the first side wall portion US1 and the second side wall portion LS1 along the spacing direction of the first side wall portion US1 and the second side wall portion LS1 causes the first side wall portion US1 and the second side wall portion LS1 to deform, and indirectly or directly transfers the extrusion or pressing force to the deformation member 14, further causing the deformation member 14 to deform, which is detected by the sensor 15. Among them, the first shell 1101 serves as the outer shell of the earphone 10, that is, the overall structural support of the earphone 10. Therefore, when the force acting on the first side wall portion US1 and / or the second side wall portion LS1 is small, the first shell 1101, which serves as the structural support, has its own structural strength sufficient to resist the force, thereby effectively reducing the probability of the first side wall portion US1 and / or the second side wall portion LS1 being deformed due to accidental touch operations such as slight collision and slight squeezing, and further effectively reducing the risk of deformation of the deformable member 15 due to accidental touch operations such as slight collision and slight squeezing, thereby effectively improving the touch accuracy of the earphone 10 and the anti-interference ability of the touch function.

[0048] It should be noted that when the first side wall portion US1 and the second side wall portion LS1 are subjected to the opposite extrusion force F1 applied from the outside along the spacing direction, either or both of the first side wall portion US1 and the second side wall portion LS1 are deformed, so that at least a portion of the area on the first side wall portion US1 and at least a portion of the area on the second side wall portion LS1 present a small displacement approaching each other along the spacing direction, thereby transmitting the extrusion force to the deformable member 14 by abutting or pulling with the deformable member 14. For example, in some embodiments, when the first side wall portion US1 and the second side wall portion LS1 are subjected to the opposite extrusion force F1 applied from the outside along the spacing direction, the first side wall portion US1 and the second side wall portion LS1 both undergo corresponding deformation displacement under the action of the opposite extrusion force F1, thereby making the first side wall portion US1 and the second side wall portion LS1 as a whole present a small displacement approaching each other along the spacing direction. For another example, in some embodiments, when the first side wall portion US1 and the second side wall portion LS1 are subjected to the opposite extrusion force F1 applied from the outside along the spacing direction, only the first side wall portion US1 or the second side wall portion LS1 undergoes corresponding deformation displacement, but the first side wall portion US1 and the second side wall portion LS1 as a whole still present a small displacement approaching each other along the spacing direction. Of course, in this embodiment, the first side wall portion US1 and the second side wall portion LS1 are configured so that when subjected to the opposite extrusion force F1, the first side wall portion US1 and the second side wall portion LS1 both undergo corresponding deformation displacement, and the deformation displacement amount of the first side wall portion US1 and the deformation displacement amount of the second side wall portion LS1 are almost equal, so that the user's comfort when pressing the earphone 10 can be effectively improved, and the earphone 10 can be effectively prevented from being subjected to an unbalanced force when subjected to the opposite pressing force of the user, causing the earphone 10 to fall from the user's ear.

[0049] Furthermore, in some embodiments, the sensor 15 is directly disposed on the deformable member 14 and is located in the bending area of ​​the deformable member 14. For example, the resistance sensor is directly attached to the surface of the bending area. With this configuration, the sensor 15 can directly sense the deformation of the deformable member 14 to receive the user's touch operation on the first side wall portion US1 and the second side wall portion LS1. Under the condition of the same sensing accuracy, the sensor 15 can sense more subtle deformations on the deformable member 14, thereby effectively improving the touch sensitivity of the earphone 10 while effectively reducing the manufacturing cost of the earphone 10.

[0050] Preferably, in some embodiments, the shell assembly 110 is the core shell of the core module 11. Since the core module 11 is located at the front side of the ear when the earphone 10 is worn, compared with the earphone components located at the back side of the ear, such as the ear hook 12, the spatial position of the core module 11 in the wearing state is more convenient for the user to operate the earphone 10. Therefore, the shell assembly 110 is set as a trigger for triggering the deformation of the deformation member 14 to control the function of the earphone 10, which can effectively improve the convenience of touch operation of the earphone 10. Further, in some embodiments, in an ear-hook earphone, the core module 11 is usually the largest part of the overall structural size of the earphone 10. Using the shell assembly 110 as a component that triggers the lateral bending of the deformation member 14 conforms to the operation habits of the human hand and effectively improves the convenience of touch operation of the earphone 10. Optionally, in some embodiments, along the thickness direction X, the spacing distance between the first side wall portion US1 and the second side wall portion LS1 is less than or equal to the maximum thickness dimension of the shell assembly 110. Such a setting can effectively improve the convenience of touch operation of the earphone 10. Preferably, in some implementations, along the thickness direction X, a spacing distance between the first side wall portion US1 and the second side wall portion LS1 is equal to a maximum thickness dimension of the housing assembly 110 .

[0051] Optionally, in some embodiments, the spacing direction is defined as an operating direction that allows the user to apply opposing pressure on the opposite sides of the shell assembly 110 when the earphone 10 is in the wearing state. Specifically, the shell assembly 110 includes a length direction Y, a width direction Z, and a thickness direction X that are orthogonal to each other. The length direction Y is defined as the direction from the free end FE toward or away from the connection end CE, and the thickness direction X is defined as the direction toward or away from the auricle when the earphone 10 is in the wearing state. In this embodiment, the spacing direction is set to be parallel to the width direction Z, that is, the first side wall portion US1 and the second side wall portion LS1 are the side walls on both sides of the first shell 1101 along the thickness direction X. In this way, when the earphone 10 is in the wearing state, the first side wall portion US1 and the second side wall portion LS1 will not be completely blocked by the user's ears and head, etc., so that the user can press the first side wall portion US1 and the second side wall portion LS1 to control the earphone 10 function of the earphone 10.

[0052] Optionally, in some embodiments, the dimensions of the first side wall portion US1 and the second side wall portion US2 along the length direction Y are larger than the dimensions along the thickness direction X. Such a configuration enables the first side wall portion US1 and the second side wall portion US2 to be more easily deformed, thereby effectively improving the pressure control comfort of the earphone 10.

[0053] Alternatively, if Figure 4-6As shown, in some embodiments, the housing assembly 110 further includes a second housing 1102 that is matched with the first housing 1101 along a preset matching direction, and the matching direction is arranged crosswise with the spacing direction, so that the assembly convenience of the earphone 10 can be effectively improved. In this embodiment, the matching direction is arranged parallel to the thickness direction X.

[0054] Furthermore, if Figure 4-6 As shown, in some embodiments, the first housing 1101 includes a side wall and a first top wall portion OS1, and the second housing 1102 includes a side wall and a second top wall portion OS2 connected to the side wall. The first side wall portion US1 and the second side wall portion LS1 are two side wall portions spaced apart from each other on the side wall of the first housing 1101 along the spacing direction.

[0055] Optionally, in some embodiments, a first ring portion 1101a is provided at one end of the side wall of the first shell 1101 away from the first top wall portion OS1, and a second ring portion 1102a is provided at one end of the side wall of the second shell 1102 away from the second top wall portion OS2, wherein the second ring portion 1102a is inserted into the inner side of the first ring portion 1101a along the mating direction, and a glue point is reserved between the first ring portion 1101a and the second ring portion 1102a at least along the spacing direction. The gap (in some embodiments of the present invention, the glue-dispensing gap includes the second gap Jx1) is used to connect and fix the first ring portion 1101a and the second ring portion 1102a by glue-dispensing, thereby effectively improving the connection stability between the first shell 1101 and the second shell 1102, and the first shell 1101 and the second shell 1102 cooperate through the first ring portion 1101a and the second ring portion 1102a, so that the outer surface of the side wall of the first shell 1101 and the outer surface of the side wall of the second shell 1102 can achieve a smooth transition connection, thereby effectively improving the aesthetics of the earphone 10. Optionally, in some embodiments, the earphone 10 includes an elastic sealant, which is disposed in the glue-dispensing gap and is used to connect and fix the first shell 1101 and the second shell 1102.

[0056] Alternatively, if Figure 7 , Fig.11As shown, in some embodiments, the deformable member 14 has a plate-like region 16. When the outer sides of the first side wall portion US1 and the second side wall portion LS1 are subjected to opposite extrusion forces, the plate-like region 16 receives the indirect or direct extrusion or pressing force transmitted to the deformable member 14, and then bends laterally. The sensor 15 is arranged on the plate-like region 16. It should be noted that the plate-like region 16 is a partial region of the deformable member 14 that is arranged in a plate shape, and does not directly limit the overall structure of the deformable member 14 to present a plate-like structure. In other words, the overall structure of the deformable member 14 can be a stick-like, rod-like, plate-like, or other structure. Therefore, the arrangement of the plate-like region 16 on the deformable member 14 enables the deformable member 14 to better "sense" the opposite forces exerted by the user on the first side wall portion US1 and the second side wall portion LS1, and to undergo corresponding deformation, so that the sensor 15 can better receive the user's touch operation signal, thereby effectively improving the control sensitivity of the headset 10. The bending region includes the plate-shaped region 16 . In other words, the plate-shaped region 16 is located in the bending region of the deformable member 14 , and its area is smaller than or equal to the area of ​​the bending region.

[0057] Alternatively, if Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, the deformable member 14 can be a circuit board 112, and the sensor 15 is directly arranged on the circuit board 112. A sensor control circuit electrically connected to the sensor 15 is arranged on the circuit board 112. The sensor control circuit performs a corresponding control function based on the electrical signal. With such a configuration, on the one hand, the sensor 15 can be directly connected to the sensor control circuit through the circuit board 112, and the circuit board 112 is used as a circuit board component for laying out the earphone 10, and is also used as the deformable member 14 to transmit the user's touch signal to the sensor 15, effectively simplifying the internal wiring and internal structure of the earphone 10, thereby effectively improving the space utilization of the earphone 10.

[0058] Alternatively, if Figure 8As shown, in some embodiments, the side edges of the circuit board 112 along the spacing direction (i.e., the side edges 1122 and 1123) are arranged in abutment with the inner walls of the first side wall portion US1 and the second side wall portion LS1, or are arranged at intervals with a certain gap. The first side wall portion US1 and the second side wall portion LS1 squeeze the opposite side edges of the circuit board 112 (i.e., the side edges 1122 and 1123) under the action of the opposite squeezing force F1, so that the main surface 1121 of the circuit board 112 is bent laterally, and the sensor 15 is arranged on the main surface 1121 of the circuit board 112. Furthermore, the overall structure of the circuit board 112 is a plate-like structure, wherein the main surface 1121 of the circuit board 112 is the board surface of the circuit board 112, and the main surface 1121 of the circuit board 112 is set at a certain preset angle to the spacing direction, wherein the preset angle is greater than or equal to 0° and less than or equal to 5°. For example, the preset angle may be 5°. Such a setting makes it easier for the circuit board 112 to deform under the extrusion of the first side wall portion US1 and the second side wall portion LS1, thereby effectively improving the control sensitivity of the earphone 10.

[0059] Specifically, in some embodiments, in a natural state, the side edges of the circuit board 112 along the spacing direction (i.e., the side edge 1122 and the side edge 1123) are arranged to abut against the inner walls of the first side wall portion US1 and the second side wall portion LS1. When the first side wall portion US1 and the second side wall portion LS1 are subjected to the opposite extrusion force F1, the first side wall portion US1 and the second side wall portion LS1 can transmit the opposite extrusion force F1 to the circuit board 112 in the first time, thereby effectively improving the control response speed of the earphone 10, and further effectively improving the user experience.

[0060] Specifically, Fig. 9As shown, in some embodiments, in a natural state and along the spacing direction, the first side wall portion US1 and the second side wall portion LS1 respectively maintain a first gap Jx2 with the side edges of the adjacent circuit board 112. Specifically, along the spacing direction, the circuit board 112 includes two side edges (i.e., side edge 1122 and side edge 1123) arranged opposite to each other, wherein one side edge 1123 is arranged adjacent to the first side wall portion US1 with a first gap Jx2, and the other side edge 1122 is arranged adjacent to the second side wall portion LS1 with a first gap Jx2. In this way, in a natural state, the first side wall portion US1 and the second side wall portion LS1 can both maintain a distance and do not contact each other, thereby preventing the first side wall portion US1 and the second side wall portion LS1 from deforming the circuit board 112 due to the user's accidental touch operation, causing the earphone 10 to randomly execute some earphone 10 functions that do not meet the user's wishes, thereby effectively improving the control accuracy of the earphone 10 and the anti-interference ability of the control function. Among them, the first gap Jx2 is the minimum distance from the inner side of the first side wall portion US1 to the circuit board 112 (that is, the distance between the inner side of the first side wall portion US1 and the side edge 1123), and the first gap Jx2 is the minimum distance from the inner side of the second side wall portion LS1 to the circuit board 112 (that is, the distance between the inner side of the second side wall portion LS1 and the side edge 1122), that is, the minimum distance from the inner side of the first side wall portion US1 to the circuit board 112 and the minimum distance from the inner side of the second side wall portion LS1 to the circuit board 112 are both set to the first gap Jx2, which can effectively ensure that the first side wall portion US1 and the second side wall portion LS1 can maintain good force stability when subjected to opposite compression, thereby preventing the earphone 10 from experiencing an unbalanced force when subjected to opposite pressing pressure from the user, causing the earphone 10 to fall from the user's ear.

[0061] Of course, in some embodiments, the minimum distance between the inner side of the first side wall portion US1 and the circuit board 112 and the minimum distance between the second side wall portion LS1 and the circuit board 112 may also be set to be unequal. For example, one of the first side wall portion US1 and the second side wall portion LS1 may directly abut against the circuit board 112, and the other may maintain a first gap Jx2 with the circuit board 112. In this way, even if the user accidentally touches the earphone 10, the other of the first side wall portion US1 and the second side wall portion LS1 can still maintain a distance from the circuit board 112 through the first gap Jx2, thereby preventing the first side wall portion US1 and the second side wall portion LS1 from squeezing the circuit board 112 at the same time, causing the circuit board 112 to deform, thereby still being able to improve the control accuracy of the earphone 10 and the anti-interference ability of the control function to a certain extent. In other words, in a natural state and along the spacing direction, only one of the first side wall portion US1 and the second side wall portion LS1 needs to be spaced apart from the circuit board 112 by the minimum distance of the first gap Jx2, which can effectively prevent the circuit board 112 from being deformed due to the user's accidental touch operation, thereby effectively improving the operation accuracy of the earphone 10 and the anti-interference ability of the control function. Among them, this article mainly describes the earphone 10 of the present application in detail based on the embodiment in which the minimum distance from the inner side of the first side wall portion US1 to the circuit board 112 and the minimum distance from the inner side of the second side wall portion LS1 to the circuit board 112 are both set to the first gap Jx2.

[0062] Optionally, in some embodiments, the first gap Jx2 is set to be larger than the deformation of the first side wall US1 and the second side wall LS1 when the opposite squeezing force F1 is the first pressure threshold, and smaller than the deformation of the first side wall US1 and the second side wall LS1 when the opposite squeezing force F1 is the second pressure threshold, the first pressure threshold is not less than 0.5 N, and the second pressure threshold is between 1 N and 5 N. The first pressure threshold is a limit value of the opposite squeezing force F1 acting on the first side wall US1 and the second side wall LS1 due to the user's accidental touch operation. Therefore, setting the first gap Jx2 to be larger than the deformation of the first side wall US1 and the second side wall LS1 when the opposite squeezing force F1 is the first pressure threshold can effectively improve the control accuracy of the earphone 10 and the anti-interference ability of the control function. Furthermore, the second pressure threshold may be a minimum value that can trigger the earphone 10 function of the earphone 10. Setting the first gap Jx2 to be smaller than the deformation of the first side wall US1 and the second side wall LS1 when the opposite extrusion force F1 is the second pressure threshold can effectively improve the pressure control comfort of the earphone 10. Among them, setting the first pressure threshold to not less than 0.5 Newton can further improve the control accuracy of the earphone 10 and the anti-interference ability of the control function. Setting the second pressure threshold to between 1 Newton and 5 Newton can further improve the pressure control comfort of the earphone 10.

[0063] Alternatively, if Figure 8 and Fig. 9 As shown, in some embodiments, as described above, the shell assembly 110 includes a second shell 1102 that is matched with the first shell 1101 along a preset matching direction, wherein the second shell 1102 includes a third side wall portion US2 and a fourth side wall portion LS2 that are opposite to each other and spaced apart along the spacing direction, the third side wall portion US2 and the fourth side wall portion LS2 are inserted between the first side wall portion US1 and the second side wall portion LS1 along the matching direction and partially overlap, and in a natural state and along the spacing direction, the first side wall portion US1 and the adjacent third side wall portion US2 and the second side wall portion LS1 and the adjacent fourth side wall portion LS2 respectively maintain a second gap Jx1, and the second gap Jx1 is greater than the first gap Jx2. Specifically, as described above, the third side wall portion US2 and the fourth side wall portion LS2 are two side wall portions spaced apart along the spacing direction along the side wall of the second shell 1102. Among them, the third side wall portion US2 and the fourth side wall portion LS2 are inserted between the first side wall portion US1 and the second side wall portion LS1 along the mating direction and partially overlap. It can be understood that after the first shell 1101 and the second shell 1102 are mated along the mating direction, the third side wall portion US2 and the portion of the third side wall portion US2 provided with the second ring portion 1102a are inserted into the inner side of the first ring portion 1101a and overlap with the first ring portion 1101a. Among them, in the natural state and along the spacing direction, the first side wall portion US1 and the adjacent third side wall portion US2 and the second side wall portion LS1 and the adjacent fourth side wall portion LS2 respectively maintain a second gap Jx1, and the second gap Jx1 is greater than the first gap Jx2. It can be understood that in the natural state and along the spacing direction, the first ring portion 1101a and the second ring portion 1102a have a second gap Jx1, which is the dispensing gap described in the above content. Among them, the first shell 1101 is the main component for receiving the opposite extrusion force F1 of the user, and the second shell 1102 has abutment relationship with the first shell 1101 along the spacing direction, so the second shell 1102 will cause a certain resistance to the deformation of the first side wall portion US1 and the second side wall portion LS1. Therefore, the second gap Jx1 is set to be larger than the first gap Jx2, which effectively reduces the resistance of the second shell 1102 to the first side wall portion US1 and the second side wall during the deformation stroke of the first side wall portion US1 and the second side wall portion LS1 squeezing the circuit board 112, thereby ensuring that the first side wall portion US1 and the second side wall can smoothly abut against the circuit board 112, so as to effectively improve the stability of the pressure control function of the earphone 10.

[0064] Alternatively, if Figure 8As shown, in some embodiments, as described above, the first housing 1101 further includes a first top wall portion OS1 connecting the first side wall portion US1 and the second side wall portion LS1, the second housing 1102 further includes a second top wall portion OS2 connecting the third side wall portion US2 and the fourth side wall portion LS2, the first top wall portion OS1 and the second top wall portion OS2 are arranged opposite to each other and spaced apart along the mating direction, and the circuit board 112 is located between the first top wall portion OS1 and the second top wall portion OS2. In which, along the mating direction, one side edge 1123 of the circuit board 112 further overlaps with the overlapping portion of the first side wall portion US1 and the third side wall portion US2, and the other side edge 1122 of the circuit board 112 further overlaps with the overlapping portion of the second side wall portion LS1 and the fourth side wall portion LS2. Specifically, as described above, along the mating direction, the first top wall is located at one end of the first side wall portion US1 and the second side wall portion LS1 and is respectively connected to the first side wall portion US1 and the second side wall portion LS1, so that the first side wall portion US1, the second side wall portion LS1 and the first top wall portion OS1 are arranged in a cantilevered manner, that is, the first side wall portion US1 and the second side wall portion LS1 are similarly suspended on the first top wall portion OS1, based on which the first side wall portion US1 and the second side wall portion LS1 are away from one end of the first top wall portion OS1 (that is, along the mating direction, close to the first side wall portion US1 The overlapping portion with the third side wall portion US2, and the overlapping portion near the second side wall portion LS1 and the fourth side wall portion LS2) are more prone to deformation, so one side edge 1123 of the circuit board 112 is further overlapped with the overlapping portion of the first side wall portion US1 and the third side wall portion US2 along the spacing direction, and the other side edge 1122 of the circuit board 112 is further overlapped with the overlapping portion of the second side wall portion LS1 and the fourth side wall portion LS2, which can be more conducive to the extrusion of the first side wall portion US1 and the second side wall portion LS1 with the circuit board 112 respectively, thereby effectively improving the stability of the voltage control function of the earphone 10.Of course, in some embodiments, along the spacing direction, the two side edges of the circuit board 112 (i.e., the side edge 1122 and the side edge 1123) can also be set to overlap with the third side wall portion US2 and the fourth side wall portion LS2, respectively, and the minimum distance between the inner side of the third side wall portion US2 and the circuit board 112 is also the first gap Jx2, and the minimum spacing distance between the inner side of the fourth side wall portion LS2 and the circuit board 112 is also the first gap Jx2. With such a setting, when the first side wall portion US1 and the second side wall portion LS1 are subjected to the opposite extrusion force F1, the first side wall portion US1 and the third side wall portion US2 can together squeeze the one side edge 1123 of the main control board circuit, and the second side wall portion LS1 and the fourth side wall portion LS2 can together squeeze the other side edge 1122 of the circuit board 112, thereby effectively preventing the first side wall portion US1 and the third side wall portion US2 from being misaligned and the second side wall portion LS1 and the fourth side wall portion LS2 from being misaligned, resulting in loosening of the first shell 1101 and the second shell 1102.

[0065] Alternatively, if Figure 5 and Fig.10 As shown, in some embodiments, as described above, the earphone 10 further includes a circuit board 112 disposed in the housing assembly 110. The deformable member 14 is independent of the circuit board 112, and a main control circuit electrically connected to the sensor 15 is disposed on the circuit board 112, and the main control circuit performs corresponding control functions based on electrical signals. Specifically, the deformable member 14 is disposed in the housing assembly 110 as an independent component, and the sensor 15 is disposed on the deformable member 14, based on which the space occupied by the sensor 15 on the main control board circuit can be effectively reduced, and the design complexity of the circuit board 112 can be reduced.

[0066] Alternatively, if Figure 5 and Fig.10 As shown, in some embodiments, along the spacing direction, the deformable member 14 includes two abutting portions 141 arranged opposite to each other, and abutting grooves are provided on the first side wall portion US1 and the second side wall portion LS1, and the two abutting portions 141 are respectively arranged in the corresponding abutting grooves. In some embodiments, the abutting portions 141 can be fixedly connected to the abutting grooves by gluing. Such a setting can effectively improve the connection stability between the deformable member 14 and the shell assembly 110 to ensure the touch stability of the earphone 10.

[0067] Preferably, if Figure 5 and Fig.10As shown, the deformable member 14 further includes an arch portion 142, wherein two abutting portions 141 are respectively connected to the two ends of the arch portion 142 and extend away from the arch portion 142 to form a complete deformable member 14, the arch portion 142 is arranged in a raised shape from the two ends of the arch portion 142 along the vertical direction of the spacing direction, the sensor 15 is arranged on the arch portion 142, and the two abutting portions 141 are respectively abutted against the first side wall portion US1 and the second side wall portion LS1. Specifically, in some embodiments, along the spacing direction, the sensor 15 is arranged in the middle of the arch portion 142. In other words, along the spacing direction, at least the middle area of ​​the arch portion 142 is arranged as a plate-shaped area 16, and the sensor 15 is arranged in the plate-shaped area 16, wherein the arch portion 142 is arranged in an arched shape from both ends of the arch portion 142 along the vertical direction of the spacing direction, and deforms when the first side wall portion US1 and the second side wall portion LS1 are subjected to the opposite extrusion force F1, and squeezes the two abutting portions 141, so that the two abutting portions 141 squeeze the arch portion 142, thereby deforming the arch portion 142. Such an arrangement enables the arch portion 142 to be better deformed when it is squeezed by the two abutting portions 141, thereby effectively improving the control accuracy of the earphone 10.

[0068] Optionally, in some embodiments, the deformable member 14 is formed by bending a plate or sheet, and the arched portion 142 is arranged in a U-shape, a U-shape or a C-shape. Of course, in some other embodiments, the deformable member 14 can also be formed by bending a rod-shaped member, a stick-shaped member or the like.

[0069] Alternatively, if Figure 5 and Fig.10 As shown, in some embodiments, as described above, the earphone 10 further includes a speaker 111 disposed in the housing assembly 110, the main surface 1121 of the circuit board 112 is overlapped with the speaker 111 along the axial direction z1 of the speaker 111, the deformable member 14 is disposed lateral to the speaker 111 along the radial direction of the speaker 111, and the main surface 143 of the deformable member 14 and the main surface 1121 of the circuit board 112 are disposed crosswise with each other, and such an arrangement can effectively improve the space utilization rate inside the housing assembly 110. In some embodiments, the thickness of the arch 142 is set to 0.2 mm, the width is set to 1.9 mm, and the length is set to 11.5 mm, wherein the width of the arch 142 is the structural length along the axial direction z1 of the speaker 111, the length of the arch 142 is the structural length along the spacing direction, and the thickness of the arch 142 is the structural length along the length direction Y of the housing assembly 110. Optionally, in other embodiments, the main surface 1121 of the circuit board 112 and the main surface 143 of the deformable member 14 are arranged to overlap with the speaker 111 along the axial direction z1 of the speaker 111 , wherein the axial direction z1 of the speaker 111 is arranged parallel to the thickness direction X of the movement module 11 .

[0070] Optionally, in some embodiments, the earphone 10 further includes an ear hook portion 12 connected to the shell assembly 110, and the ear hook portion 12 is used to place the shell assembly 110 on the front side of the user's auricle when worn. The deformable member 14 is arranged on the side of the speaker 111 close to the ear hook along the radial direction of the speaker 111. Such an arrangement can effectively improve the space utilization of the shell assembly 110.

[0071] Alternatively, if Figure 6 and Fig.11 As shown, in some embodiments, the deformable member 14 can also be a second shell 1102, specifically, the second shell 1102 includes a third side wall portion US2, a fourth side wall portion LS2 and a second top wall portion OS2, wherein the second shell 1102 cooperates with the first shell 1101 in the manner described in the above embodiment, and the sensor 15 is arranged on the second top wall portion OS2, when the first side wall portion US1 and the second side wall portion LS1 are subjected to the opposite extrusion force F1 and deform, the first side wall portion US1 and the second side wall portion LS1 respectively squeeze the third side wall portion US2 and the fourth side wall portion LS2, so that the third side wall portion US2 and the fourth side wall portion LS2 pull the second top wall portion OS2, and the second top wall portion OS2 is deformed, and the sensor 15 arranged on the second top wall portion OS2 detects the deformation of the second top wall portion OS2 and generates an electrical signal. The sensor 15 is electrically connected to the circuit board 112 through the soft circuit board 17 / wire assembly, so as to transmit the electrical signal to the main control circuit of the circuit board 112. Such a configuration can effectively simplify the structure of the earphone 10 and optimize the space utilization of the earphone 10 .

[0072] Moreover, in some embodiments, the circuit board 112 is located between the speaker 111 and the second top wall portion OS2. This configuration allows the sensor 15 to be as close to the circuit board 112 as possible, thereby reducing the length of the flexible circuit board 17 and effectively improving the internal space utilization of the shell assembly 110.

[0073] Optionally, in some embodiments, the deformable member 14 may also be the top wall of the first shell 1101 , for example, the first top wall portion OS1 .

[0074] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application.
