A headset

Abstract

An earphone comprises a shell part, an adapter part, an ear hook part, a loudspeaker and a key assembly. The adapter part has a contact area which contacts the front side of the ear in the wearing state of the earphone and a non-contact area which does not contact the human body. At least another part of the key assembly is exposed to the non-contact area of the adapter part. Since the key assembly is located in the adapter part, the pressing force generated by pressing the key assembly is transmitted to the ear hook part, which provides stable support force for the key assembly to improve the stability of the pressing operation of the key assembly. The key assembly is not located in the shell part where the loudspeaker is located, and does not occupy the installation space in the shell part. The shell part provides a larger installation space for the loudspeaker, so that the loudspeaker can adopt a larger magnetic circuit assembly to improve the acoustic output. Moreover, the key assembly is located in the adapter part, so that the key assembly is more easily exposed outside the ear, which facilitates the user to easily operate and use the key assembly, thereby improving the convenience of the operation of the key assembly.

Description

Technical Field

[0001] This application relates to the field of acoustic technology, and specifically to an air-conducting headphone, and more particularly to an open-back air-conducting ear-hook headphone. Background Technology

[0002] Open-back headphones have become an indispensable tool in people's daily lives and work. They can be used with mobile phones, computers, and other terminal devices to provide users with an auditory feast and an open sound field environment. Currently, commonly used open-back air-conduction ear-hook headphones do not insert the speaker shell into the ear canal after wearing them, but rather rest against the concha wall. The contact area between the shell and the human body is relatively small, which improves wearing comfort, but reduces stability.

[0003] To facilitate user operation of headphone functions, corresponding buttons need to be installed on the headphones. Currently, for open-back, air-conductive ear-hook headphones, mechanical buttons are generally located on a large area of ​​the shell for easy operation. However, due to the relatively poor stability of the shell, pressing the mechanical buttons may result in button failure due to the lack of support, or misalignment of the shell affecting fit. Therefore, open-back, air-conductive ear-hook headphones often use touch-sensitive capacitive buttons. However, this presents other problems, such as being prone to accidental touches and being easily covered by sweat, rain, or other external substances, leading to touch button failure. Utility Model Content

[0004] This invention provides an open-type air conduction earhook headphone to solve the problem of unstable mechanical button pressing support in open-type air conduction earhook headphones.

[0005] In some embodiments, an earphone is provided, including a housing, an adapter, an ear hook, a speaker, and a button assembly, wherein the housing, the adapter, and the ear hook are connected in sequence; in the earphone wearing state, the housing and the adapter are located on the front side of the ear, the ear hook is located on the top and back side of the ear, one end of the housing away from the adapter abuts against the concha wall, and there is a gap space between the housing and the concha wall that communicates with the outside air and the external auditory canal; the housing has a first receiving cavity, and the speaker is located in the first receiving cavity; the adapter has a contact area that contacts the front part of the ear in the earphone wearing state and a non-contact area that does not contact the human body, and the button assembly is located in the non-contact area of ​​the adapter.

[0006] In some embodiments, the housing portion is an integral cylindrical structure, and the end of the housing portion connected to the adapter portion has an opening.

[0007] In some embodiments, the adapter has an inner side facing the human body when worn, an outer side facing away from the human body, an upper side facing upward, and a lower side facing downward; the contact area includes at least the inner side, the non-contact area includes at least the outer side and a portion of the upper side, and the button assembly is located on the upper side or the outer side of the non-contact area.

[0009] In some embodiments, the housing portion has a split surface perpendicular to the thickness direction, and the button assembly is located on the side of the upper surface of the adapter that is away from the human body relative to the split surface.

[0010] In some embodiments, when the headphones are worn, the headphones form a clear surface with the human ear, and the button assembly is located on the outside of the non-contact area of ​​the adapter relative to the clear surface, facing away from the human body.

[0011] In some embodiments, the angle between the central axis of the button assembly and the clearance surface is 0-30°.

[0012] In some embodiments, the curvature of the outer surface of the adapter near the end of the housing is less than the curvature of the adapter near the other end of the ear hook portion, and the button assembly is located at the end of the adapter near the housing portion.

[0013] In some embodiments, when the earphone is worn, the position where the end of the housing portion away from the adapter portion abuts against the concha cavity is the first force-bearing position between the earphone and the ear, the position where the ear hook portion rests against the upper end of the ear is the second force-bearing position between the earphone and the ear, and the distance between the button assembly and the second force-bearing position is less than the distance between the button assembly and the first force-bearing position.

[0014] In some embodiments, the button assembly includes a button, a pressing portion, and a pressing block, with the pressing block located between the button and the pressing portion along the pressing direction; the adapter includes an adapter housing for forming a third receiving cavity, the adapter housing having a through opening; the button is located within the third receiving cavity, at least a portion of the pressing block is movably located within the opening, and at least a portion of the pressing portion is located on the side of the opening away from the third receiving cavity.

[0015] In some embodiments, the pressing block is a cantilever structure and is integrated with the adapter housing. The pressing block includes a connecting end fixedly connected to the adapter housing and a free end that is suspended and movable. Along the thickness direction of the housing portion, in the wearing state, the connecting end of the pressing block is closer to the human body than the free end.

[0016] In some embodiments, the adapter further includes a flexible outer layer covering the outside of the adapter housing, and the pressing portion is part of the outer layer.

[0017] In some embodiments, the ear hook portion includes an ear hook cover, the outer layer being integrally formed with the ear hook cover.

[0018] In some embodiments, the adapter is provided with a separator to separate the first receiving cavity of the housing and the third receiving cavity of the adapter, and the separator is sealed to the adapter.

[0019] In some embodiments, the earphone further includes a circuit board, an adapter circuit board, and a battery. The end of the ear hook away from the adapter is disposed in a second accommodating cavity. The battery and the circuit board are located in the second accommodating cavity. The adapter circuit board is located in the third accommodating cavity. The circuit board is electrically connected to the battery and electrically connected to the speaker through the adapter circuit board. The button assembly is electrically connected to the adapter circuit board.

[0020] In some embodiments, the adapter circuit board includes a first adapter circuit board, the button assembly is connected to the first adapter circuit board, the central axis of the button assembly is parallel to or coincides with the first adapter circuit board; the button is fixed to the side of the first adapter circuit board, and the button is perpendicular to the first adapter circuit board.

[0021] In some embodiments, the adapter circuit board further includes a second adapter circuit board, and the circuit board, the first adapter circuit board, the second adapter circuit board and the speaker are electrically connected in sequence; the first adapter circuit board and the second adapter circuit board are stacked at an angle to each other, and the second adapter circuit board is closer to the speaker than the first adapter circuit board; the second adapter circuit board is parallel to the end face of the speaker facing the second adapter circuit board.

[0022] According to the headphones of the above embodiment, the button assembly is located in the adapter section, not in the housing section where the speaker is located. The button assembly is close to the ear hook section, away from the support position where the housing section contacts the concha, and closer to the position where the ear hook section abuts the upper part of the ear. With this configuration, during the pressing operation, the pressing force generated by pressing the button assembly is transmitted to the ear hook section, which provides stable support for the button assembly. This allows the user to easily press the button assembly without disturbing the wearing position of the headphones.

[0023] The button assembly is located in the adapter section, while the speaker is located in the housing section; the button assembly is not located in the housing section where the speaker is located. This arrangement means the button assembly does not occupy mounting space within the housing section, providing more mounting space for the speaker and improving acoustic output. For example, more mounting space allows the speaker 40 to use a larger magnetic circuit assembly, resulting in increased driving force and enhanced acoustic output.

[0024] The adapter is located between the shell and the ear hook. When the headphones are worn, the adapter is positioned outside the concha, protruding more from the ear than the shell. The button assembly is located in the adapter, making it more easily exposed on the outside of the ear and less likely to be obstructed, thus facilitating easier operation and improving the convenience of button operation.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0028] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0029] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0030] Figure 1 This is a schematic diagram illustrating the physiological structure of an exemplary ear based on headphones provided in some embodiments of this application. Please refer to... Figure 1 The exemplary ear may include physiological parts such as the external auditory canal 101, the concha 102, the cymba conchae 103, the triangular fossa 104, the antihelix 105, the scaphoid fossa 106, the helix 107, the earlobe 108, and the crus of the helix 109. Although the external auditory canal 101 has a certain depth and extends to the tympanic membrane of the ear, unless otherwise specified, the external auditory canal 101 can be understood as its entrance (i.e., the ear canal) away from the tympanic membrane. Furthermore, the physiological parts such as the concha 102, the cymba conchae 103, and the triangular fossa 104 have a certain volume and depth in three-dimensional space, and the concha 102 is directly connected to the external auditory canal 101, which can be simply regarded as the aforementioned ear canal being located at the bottom of the concha 102.

[0031] Regarding the headphones provided in some embodiments of this application, stable wearing of the headphones can be achieved by means of one or more physiological parts of the ear.

[0032] For example, since the external auditory canal 101, concha 102, cymba concha 103, triangular fossa 104, and other physiological parts have a certain depth and volume in three-dimensional space, they can meet the requirements for stable wearing of the headphones. When the headphones are in the wearing state, the entire or part of the headphone structure can contact the upper part of the external auditory canal 101 (such as one or more physiological parts such as the concha 102, cymba concha 103, triangular fossa 104, antihelix 105, scaphoid 106, helix 107, and crus of helix 109); when the headphones are in the wearing state, the entire or part of the headphone structure can also be located within one or more physiological parts of the ear, for example, located in Figure 1 The first region P1, enclosed by the dashed line, includes at least the auricular sac 103 and the triangular fossa 104. For example, located in... Figure 1 The second region P2, enclosed by the dashed line, contains at least the concha cavity 102.

[0033] For example, when the headphones are in the wearing state, the entire or part of the headphone structure may also be located on the front side of the helix foot 109, for example Figure 1 Within the third region P3 enclosed by the dashed line.

[0034] Due to individual differences among users, ears may vary in shape, size, and other dimensions. To facilitate description and understanding, and to minimize or even eliminate these individual differences, unless otherwise specified, this application primarily uses an ear model with a "standard" shape and size as a reference to describe the structure of the headphones in different embodiments and how they are worn on that ear model. For example, a simulator (such as the GRAS 45BC KEMAR) containing a head and its (left and right) ears can be manufactured based on ANSI:S3.36, S3.25, and IEC:60318-7 standards as a reference for wearing headphones, thus representing the scenario of most users normally wearing headphones.

[0035] Therefore, descriptions such as "user wearing," "in wearing state," and "in earphone wearing state" in this application can refer to the earphones described in this application being worn on the ears of the aforementioned simulator. Of course, considering the individual differences among different users, the structure, shape, size, thickness, etc. of one or more parts of the ear can be differentiated according to different ear shapes and sizes. These differentiated designs can be manifested in the characteristic parameters of one or more parts of the earphone having different ranges of values ​​to adapt to different ears.

[0036] It should be noted that in fields such as medicine and anatomy, the human body can be defined by three basic planes: 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.

[0037] In this context, the sagittal plane is a section perpendicular to the ground along the anteroposterior direction of the body, dividing the body into left and right parts; the coronal plane is a section perpendicular to the ground along the lateral direction of the body, dividing the body into anterior and posterior parts; and the horizontal plane is a section parallel to the ground along the vertical direction of the body, dividing the body into superior and inferior parts. Correspondingly, the sagittal axis is the axis along the anteroposterior direction of the body and perpendicular to the coronal plane, the coronal axis is the axis along the lateral direction of the body and perpendicular to the sagittal plane, and the vertical axis is the axis along the vertical direction of the body and perpendicular to the horizontal plane.

[0038] Furthermore, the "anterior side of the ear" mentioned in this application is a concept relative to "posterior side of the ear." The former refers to the side of the ear facing the positive axial direction of the external auditory canal 101, while the latter refers to the side facing away from the positive axial direction of the external auditory canal 101. Both refer to the user's ear. The positive axial direction of the external auditory canal 101 refers to the direction in which the axial direction of the external auditory canal 101 is away from the tympanic membrane. Observing the ear of the simulator along the direction of the human coronal axis, one can obtain... Figure 1 The diagram shows the front outline of the ear.

[0039] It should be noted that the above description of the ear is for illustrative purposes only and is not intended to limit the scope of this application. Those skilled in the art can make various changes and modifications based on the description in this application, and such changes and modifications still fall within the protection scope of this application.

[0040] Please refer to Figures 2 to 11 In some embodiments, an earphone is provided. This earphone is an open-back, air-conductive earhook earphone. The earphone transmits audio to the user through the air and does not block the external auditory canal 101, allowing the external auditory canal 101 to communicate with the outside world when the earphone is worn. The earphone has a C-shaped or spiral structure, is worn on the upper part of the ear, with one end extending to abut against the concha 102 and the other end extending to the back of the ear. Exemplarily, the earphone mainly includes a housing 10, an adapter 20, an earhook 30, a speaker 40, a button assembly 50, and a circuit board 60. The earphone may also include a battery assembly, a microphone assembly, and other functional components as needed (e.g., antenna structure, wear detection structure, etc.). The button assembly 50 is a mechanical button. The user can apply pressure perpendicular to the button surface of the button assembly 50 to move the button assembly 50 along the pressing direction to trigger the corresponding button function.

[0041] Please refer to Figure 3 and Figure 4 The adapter 20 connects the housing 10 and the ear hook 30. The housing 10, adapter 20, and ear hook 30 roughly constitute the overall outline of the earphone. The housing 10 provides structural assembly space for components such as the speaker 40 and microphone assembly. One or more of the adapter 20 and ear hook 30 can provide structural assembly space for functional components such as the circuit board 60, battery assembly, and microphone assembly.

[0042] The adapter 20 can be understood as a transitional structure connecting the housing 10 and the ear hook 30 for accommodating some of the headphone's electronic components. For example, the adapter 20 can be a part of the housing 10, such as the portion of the housing 10 used to connect to the ear hook 30 and occupying a certain structural space can be regarded as the adapter 20. For example, the adapter 20 can also be a part of the ear hook 30, such as the portion of the ear hook 30 used to connect to the housing 10 and occupying a certain structural space can be regarded as the adapter 20. For example, the housing 10, the adapter 20, and the ear hook 30 are relatively independent structures. By connecting the adapter 20 between the housing 10 and the ear hook 30, the general outline of the headphone as a whole can be assembled.

[0043] Please refer to Figure 2 When the headphones are worn, the housing 10 and the adapter 20 are located on the front side of the ear, and the ear hook 30 is located on the top and back side of the ear. The ear hook 30 has a C-shaped curved structure and extends from the front side of the ear, around the top of the ear, to the back side of the ear, so that it hangs on the ear when the headphones are worn. For example, the housing 10 can be positioned near the external auditory canal 101 but not blocking the external auditory canal 101 when the headphones are worn, so that the headphones are open-back headphones. Specifically, when the headphones are worn, the end of the housing 10 away from the adapter 20 abuts against the concha wall. The housing 10 has a long strip structure, and there is a gap space between the upper and / or lower side of the housing 10 and the concha wall that connects to the outside air and the external auditory canal, so that the headphones do not close the external auditory canal, forming an open-back design. It should be noted that due to individual differences among users, when the earphone is worn by different users, the shell part 10 may partially cover the external auditory canal 101, but the external auditory canal 101 is still not blocked and is connected to the outside.

[0044] To improve stability while wearing the headphones, the headphones can employ any one or a combination of the following methods.

[0045] Firstly, at least a portion of the ear hook portion 30 is configured as a contoured structure (e.g., an arc-shaped hook) that conforms to at least one of the back of the ear and the head, thereby increasing the contact area between the ear hook portion 30 and the ear or head, and thus increasing the resistance to the headphones falling off the ear.

[0046] Secondly, at least a portion of the ear hook 30 is configured as an elastic structure, so that the ear hook 30 has a certain elastic deformation when the headphones are worn, in order to increase the pressure of the ear hook 30 on the ear or head, thereby increasing the resistance to the headphones falling off the ear.

[0047] Third, at least a portion of the ear hook 30 is configured to rest against the head when the headphones are worn, so that the ear hook 30 generates a reaction force that presses against the ear, causing the housing 10 to press against the front of the ear, thereby increasing the resistance to the headphones falling off the ear.

[0048] Fourth, the housing part 10 and the ear hook part 30 are configured to clamp the physiological parts such as the area where the helix 107 and the area where the concha 102 are located from the front and back sides of the ear when the earphone is worn, thereby increasing the resistance to the earphone falling off the ear.

[0049] Fifth, the housing portion 10 or other auxiliary structures connected to the housing portion 10 (such as the adapter portion 20) are configured to extend at least partially into physiological parts such as the concha cavity 102, cymba conchae 103, triangular fossa 104 and scaphoid 106 when the earphone is worn, thereby increasing the resistance to the earphone falling off the ear.

[0050] Please refer to Figure 2 When the headphones are worn, there are two main force-bearing positions between the headphones and the ear: a first force-bearing position P4 and a second force-bearing position P5. The first force-bearing position P4 is located at the end of the housing 10 away from the adapter 20, where it abuts against the concha 102. The force at this position is abutting and supporting force. The direction of the force at the first force-bearing position P4 is forward along the sagittal axis and tilted upward. Since the concha 102 is a concave cavity, the support stability at the first force-bearing position P4 is relatively poor, and it is easy to move, such as sliding. The second force-bearing position P5 is located at the position where the curved ear hook 30 rests against the upper end of the ear. The ear hook 30 forms a wearing state that surrounds the upper end of the ear. At the second force-bearing position P5, the upper end of the ear provides an upward supporting force to the ear hook 30 along the vertical axis. The support stability at the second force-bearing position P5 is high, and it is not easy to move.

[0051] In some embodiments, the button assembly 50 can be located closer to the second force-bearing position P5, and correspondingly, the button assembly 50 is located further away from the first force-bearing position P4. For example, the distance between the button assembly 50 and the second force-bearing position P5 is less than the distance between the button assembly 50 and the first force-bearing position P4. This configuration ensures that the pressing force applied by the user to the button assembly 50 is primarily transmitted to the second force-bearing position P5. During the pressing process, the ear hook portion 30 provides a vertically upward supporting force at the second force-bearing position P5, providing stable support for button operation and improving the stability of the button assembly 50's pressing operation. This avoids problems such as earphone movement, loosening, or detachment during button pressing.

[0052] In some embodiments, the button assembly 50 is located outside the housing portion 10, for example, the button assembly 50 is located in the adapter portion 20, or the button assembly 50 is located in the ear hook portion 30. This arrangement ensures that the button assembly 50 does not occupy space within the housing portion 10, allowing more space in the housing portion 10 to accommodate a larger speaker 40, thereby improving the headphone's audio performance. The following description uses the example of the button assembly 50 being located in the adapter portion 20 as an example.

[0053] The housing portion 10 has a first receiving cavity 10a, the adapter portion 20 has a third receiving cavity 20a, and the ear hook portion 30 has a second receiving cavity 30a. The adapter portion 20 is located between the housing portion 10 and the ear hook portion 30, and connects the housing portion 10 and the ear hook portion 30 respectively. When the headphones are worn, the adapter portion 20 is positioned further away from the external auditory canal 101 than the housing portion 10, along the direction of the human coronal axis. The speaker 40 is located within the first receiving cavity 10a of the housing portion 10, and the circuit board 60 can be installed within the third receiving cavity 20a of the adapter portion 20 or the second receiving cavity 30a of the ear hook portion 30. The button assembly 50 is located within the adapter portion 20. When the headphones are worn, the adapter portion 20 has a contact area A1 that contacts the human body (e.g., the front part of the ear) and a non-contact area A2 that does not contact the human body. The button assembly 50 is located within the non-contact area A2 of the adapter portion 20. This design ensures that the button assembly 50 is not obstructed by the human body when the headphones are worn, allowing users to touch and press it, thus improving the ease of operation of the button assembly 50.

[0054] It should be noted that the speaker 40 and the button assembly 50 can be electrically connected to the circuit board 60 via flexible flat cables, wires, or other electrical connection structures. The speaker 40 can convert electrical signals into sound signals, which can be used to output noise-canceling sounds, user voices, and audio played according to user needs (such as music, alert sounds, etc.). The circuit board 60 can be understood as the main control board or motherboard of the headphones and a collection of related components. The circuit board 60 plays a role in regulating and managing all or some of the functional components in the headphones; for example, it is used to convert and process electrical signals in the headphones to support the realization of various headphone functions (such as supporting the headphones to power on / off, switch playback content, increase or decrease volume, etc.). The button assembly 50 can use pressing operations to realize different control electrical signals, and the circuit board 60 realizes corresponding response control according to the control electrical signals; the response control may include, but is not limited to, powering on / off the headphones, adjusting the volume, turning noise-canceling mode on / off, and switching playback audio content, etc. The button assembly 50 can realize different control electrical signals through different operation methods, including but not limited to long press, light touch (short press), single click, double click, triple click, etc.

[0055] In this embodiment, the button assembly 50 is located in the adapter 20, so that the button assembly 50 does not occupy the installation space of the housing 10. The housing 10 can provide a larger installation space for the speaker 40 (that is, the first accommodating cavity 10a of the housing 10 is only used to install the speaker 40, or the speaker 40 and its necessary electrical connection structure), which allows for the installation of a larger speaker 40. The larger speaker 40 has better sound quality, which ultimately improves the sound quality of the headphones.

[0056] Please refer to Figures 3 to 8 In some embodiments, the housing portion 10 includes an inner wall 11 facing the ear when worn, an outer wall 12 away from the ear, an upper wall 13 facing the top of the head, and a lower wall 14 facing the soles of the feet. The inner wall 11 and outer wall 12 are located on opposite sides of the thickness direction (vibration direction of the speaker 40) of the housing portion 10, while the upper wall 13 and lower wall 14 are located on opposite sides of the housing portion 10 along its minor axis. The outer wall 12, upper wall 13, inner wall 11, and lower wall 14 are sequentially connected to form a first accommodating cavity 10a. The outer wall 12, upper wall 13, inner wall 11, and lower wall 14 can each be a planar or curved structure. Rounded chamfers can be provided at the points where the outer wall 12, upper wall 13, inner wall 11, and lower wall 14 connect to each other, making the outer contour of the housing portion 10 smoother, improving wearing comfort and aesthetics.

[0057] It should be noted that the housing portion 10 has mutually perpendicular major axis, minor axis, and thickness direction. The thickness direction is parallel to the vibration direction of the speaker 40 within the housing portion 10. When the headphones are worn, the vibration direction of the speaker 40 is parallel to the coronal axis and faces the human body. The vibration direction of the speaker 40 is also towards the inner wall 11 of the housing portion 10 closest to the human body, so that the sound emitted by the speaker 40 propagates towards the ear. When the headphones are worn, the major axis of the housing portion 10 is approximately aligned with the sagittal axis of the human body, and the major axis can be slightly tilted relative to the anterior-posterior direction of the human body. The minor axis of the housing portion 10 is approximately aligned with the vertical axis of the human body, and the thickness direction of the housing portion 10 is approximately aligned with the coronal axis of the human body.

Figure 2 The long axis is inclined relative to the sagittal axis of the human body, and the long axis is closer to the sagittal axis of the human body than the short axis; the short axis is inclined relative to the vertical axis of the human body, and the short axis is closer to the vertical axis of the human body than the long axis.

[0058] In some embodiments, the housing portion 10 can be a cylindrical structure such as rectangular, cylindrical, elliptical cylindrical, or rhomboid. One end of the housing portion 10 connected to the adapter 20 has an opening. After the housing portion 10 is connected to the adapter 20, the adapter 20 seals the opening of the housing portion 10 facing the adapter 20. With this configuration, the speaker 40 can be inserted into the first receiving cavity 10a of the housing portion 10 using a plug-in method. Specifically, the speaker 40 is inserted into the first receiving cavity 10a of the housing portion 10 through the opening at one end, and then the adapter 20 or the flexible wall 15 is used to seal the corresponding opening, thus completing the installation of the speaker 40. Since the installation of the button assembly 50 does not need to be considered, the plug-in method allows for quick and convenient installation of the speaker 40, simplifying the installation steps and improving installation efficiency. Furthermore, it ensures the installation accuracy of the speaker 40, ensuring that the vibration direction of the speaker 40 is parallel to the thickness direction of the housing portion 10.

[0059] In some embodiments, since there is no need to consider setting the button assembly 50 in the housing portion 10, the housing portion 10 can be an integral cylindrical structure. The integrally formed main housing has higher structural stability and can also form a seamless appearance surface.

[0060] Please refer to Figure 3 , Figure 4 and Figure 5 The outer surface of the adapter 20 includes an inner side 20b, an outer side 20c, an upper side 20d, and a lower side 20e. When the headphones are worn, the inner side 20b faces the body, the outer side 20c faces away from the body, the upper side 20d faces the top of the head, and the lower side 20e is located away from the top of the head. The inner side 20b and outer side 20c can be flat or curved, while the upper side 20d and lower side 20e are curved.

[0061] In some embodiments, the button assembly 50 is located in the adapter 20, and the button assembly 50 is located in the non-contact area A2 of the adapter 20. Specifically, when the headphones are worn, the contact area A1 of the adapter 20 that contacts the human body includes the inner side 20b, and the non-contact area A2 that does not contact the human body includes the outer side 20c. In other embodiments, the contact area A1 may also include a small portion of the upper side 20d or the lower side 20e, and the non-contact area A2 that does not contact the human body may also include most of the upper side 20d or the lower side 20e. Figure 5 This is only a schematic diagram of the contact area A1 and the non-contact area A2. The shaded area in the adapter 20 is the contact area A1, and the unshaded area is the non-contact area A2. The contact area A1 and the non-contact area A2 between the adapter 20 and the human body may be different. Figure 5There is a certain degree of error in the area shown. This design ensures that the operating space of the button assembly 50 is unobstructed by the ear, so that the user will not touch their ear when pressing the button assembly 50, thus improving the user experience during button operation.

[0062] Please refer to Figures 2 to 8 In some embodiments, the button assembly 50 is located in the non-contact area A2 of the upper side 20d of the adapter 20. With this configuration, when the headphones are worn, the pressing direction of the button assembly 50 is approximately parallel to the vertical axis or slightly inclined relative to the vertical axis, and the pressing direction points away from the top of the head. This makes the pressing direction of the button assembly 50 approximately parallel to and opposite to the direction of the supporting force at the second force-bearing position P5. This improves the stability of the button assembly 50 when pressed by the finger, avoids misalignment or other movement of the headphones during button pressing, and thus enhances the stability of the headphones when operating the button assembly 50, making it easier for the user to operate.

[0063] In other embodiments, the button assembly 50 is located in the non-contact area A2 of the outer surface 20c of the adapter 20. With this configuration, when the headphones are worn, the pressing direction of the button assembly 50 points towards the human body, thus generating a pressing force towards the human body. This makes the pressing direction of the button assembly 50 approximately parallel to and opposite to the direction of the supporting force at the first force-bearing position P4. This improves the stability of pressing the button assembly 50 with a finger, avoids misalignment or other movement of the headphones during button pressing, and enhances the stability of the headphones when operating the button assembly 50, making it easier for the user to operate.

[0064] It should be noted that when the button assembly 50 is positioned too inwardly on the upper side 20d of the non-contact area A2 of the adapter 20, the operable space for pressing the button assembly 50 is small, and the user may easily touch their ear, affecting the operating experience. When the button assembly 50 is positioned too downwardly on the outer side 20c of the non-contact area A2 of the adapter 20, pressing the button assembly 50 may create upward pressing force, easily causing the earphone to fall out of the ear. In some embodiments, when the earphone is worn, viewed along the short axis, the button assembly 50 is located on the outer side of the non-contact area A2 of the adapter 20; viewed along the thickness direction, the button assembly 50 is located on the upper side of the non-contact area A2 of the adapter 20. Specifically, "outer side" refers to the direction away from the human body in the thickness direction of the housing portion 10, and "upper side" refers to the direction pointing towards the top of the head in the short axis direction of the housing portion 10. This design allows the user to utilize the support force provided by the ear to the headphone, which is directed away from the body and towards the top of the head, when pressing the button assembly 50. This is the support force of the first force-bearing position P4 and the second force-bearing position P5, which further improves the stability of the finger pressing the button assembly 50 and makes it easier for the user to operate.

[0065] In the above embodiments, due to the support provided by the ear to the earphone, the user can press the button assembly 50 with a single finger to perform button operation. However, to improve pressing stability, the user can also use two fingers to press the button assembly 50. Specifically, one finger rests against the lower side 20e of the adapter 20, while the other finger presses the button assembly 50 located on the adapter 20. The two fingers pinch two areas of the adapter 20, with the finger resting against the lower side 20e providing support. This improves the stability of pressing the button assembly 50, further reducing earphone movement during pressing and not affecting normal earphone use. Furthermore, using two fingers reduces pressure on the ear by having the pressing force borne by the user's fingers, improving the comfort of button operation.

[0066] Please refer to Figure 6 In some embodiments, when the headphones are worn, the headphones and the user's ear form a clear surface p1. Using the clear surface p1 as a boundary, on the side of the clear surface p1 facing the user, the top of the headphones is obstructed by the user's ear; on the side of the clear surface p1 facing away from the user, the top of the headphones is not obstructed by the user's ear. The button assembly 50 is located on the non-contact area A2 of the adapter 20, on the outer side facing away from the user's ear relative to the clear surface p1. This configuration creates a clear area above the button assembly 50, without any ear obstruction or interference, allowing the user to easily press the button assembly 50, improving the convenience of using the button assembly 50, and also preventing the user from touching their ear when operating the button assembly 50, thus improving the user experience.

[0067] Furthermore, in some embodiments, the central axis of the button assembly 50 is inclined outwards away from the ear, with the upper end of the central axis further away from the human body than the lower end. The central axis of the button assembly 50 is inclined relative to the clearance surface p1; for example, the angle between the central axis of the button assembly 50 inclined outwards away from the ear and the clearance surface p1 is 0-30°. With this configuration, the pressing direction of the button assembly 50 extends downwards from the upper outer side of the ear, allowing the user to press the button assembly 50 from a position further away from the ear, making it easier for the user to press the button assembly 50, improving the convenience of using the button assembly 50, and further preventing the button assembly 50 from touching the ear, thus enhancing the user experience.

[0068] In the case of wearing headphones, the projection of the connection between the adapter 20 and the housing 10 along the thickness direction of the housing 10, pointing to the highest point on the top of the head, is the first projection point; the projection of the connection between the adapter 20 and the ear hook 30 along the thickness direction of the housing 10, pointing to the innermost point of the external auditory canal, is the second projection point; and the highest point on the top of the head where the ear hook 30 contacts the ear is the third projection point. The clear surface p1 can be a plane formed by the first, second, and third projection points. The central axis of the button assembly 50 can be a straight line perpendicular to the pressing area and pointing to the top of the head.

[0069] In some embodiments, when the headphones are worn, since the housing portion 10 extends forward towards the ear and one end abuts against the concha cavity 102, and the ear hook portion 30 extends backward and is mounted behind the ear, the adapter portion 20 is bent between the housing portion 10 and the ear hook portion 30. Specifically, the adapter portion 20 is bent towards the top of the head along the long axis of the housing portion 10. This arrangement provides sufficient clearance in the length direction of the housing portion 10, allowing the headphones to be worn stably and comfortably on the ears. For example, the upper side 20d and the lower side 20e are bent towards the top of the head along the long axis of the housing portion 10. Further, in some embodiments, the adapter portion 20 is bent towards the human body along the thickness direction of the housing portion 10. This arrangement provides sufficient clearance in the thickness direction of the housing portion 10, allowing the headphones to be worn stably and comfortably on the ears. For example, the inner side 20b and the outer side 20c are bent towards the human body along the thickness direction of the housing portion 10.

[0070] Please refer to Figure 7 In some embodiments, to allow the adapter 20 to more smoothly connect the housing portion 10 and the ear hook portion 30, the curvature of the outer surface of the adapter 20 near the housing portion 10 is less than the curvature of the other end of the adapter 20 near the ear hook portion 30. The curvature of the outer surface of the adapter 20 can be the curvature of the boundary contour line projected onto the housing portion 10 in the thickness direction or the minor axis direction when the earphone is worn.

[0071] Furthermore, in some embodiments, the button assembly 50 is located at the end of the adapter 20 near the housing portion 10. With this configuration, the button assembly 50 is located on the outer surface of the adapter 20 with a small curvature, making it easier for the user to press the button assembly 50. The pressing area of ​​the button assembly 50 is more parallel to the outer surface of the adapter 20, exposing a larger pressing area, which is also beneficial for pressing operations.

[0072] In some embodiments, the button assembly 50 is located further outward on the adapter portion 20. For example, the housing portion 10 has a split surface perpendicular to the thickness direction, and the center point of the pressing area of ​​the button assembly 50 is located on the side of the upper surface 20d of the adapter portion 20 that is farther away from the human body relative to the split surface. With this configuration, when the headphones are worn, the pressing area of ​​the button assembly 50 is not obstructed by the upper ear in the vertical axis direction, making it easier for the user to press and operate the button assembly 50. Furthermore, using the pressing assembly 50 does not involve contact with the human body, resulting in a better user experience.

[0073] It should be noted that in the above embodiments of this patent, the button position can be the center point of the area of ​​the button assembly 50 that is pressed by the user, or it can be the center point of the outer surface of the pressing part 52 in subsequent embodiments.

[0074] Please refer to Figure 8 In some embodiments, the button assembly 50 includes a button 51, a pressing part 52, and a pressing block 53, with the pressing block 53 located between the button 51 and the pressing part 52 along the pressing direction. Specifically, when the user presses the pressing part 52, the pressing part 52 moves towards the pressing block 53 along the pressing direction. The pressing block 53, compressed by the pressing part 52, moves towards the button 51 along the pressing direction until the button 51 is triggered. The button 51 is an electronic functional component electrically connected to the circuit board 60. When triggered, it generates a touch signal and transmits it to the circuit board 60, which controls the implementation of the corresponding function based on the signal. Exemplarily, the pressing part 52 and the pressing block 53 can be separate structures or an integrated structure.

[0075] In some embodiments, the adapter 20 includes an adapter housing for forming a third receiving cavity 20a of the adapter 20, and has a through opening 201. The button 51 is mounted within the third receiving cavity 20a, at least a portion of the pressing block 53 is movably located within the opening 201, and at least a portion of the pressing part 52 is located outside the opening 201 (i.e., on the side away from the third receiving cavity 20a). This arrangement allows the pressing part 52 to be pressed by the user outside the opening 201, while the pressing block 53 moves within the opening 201 along the pressing direction.

[0076] Please refer to Figure 9 In some embodiments, the pressing block 53 is a cantilever structure. One end of the pressing block 53 is fixedly connected to the adapter housing to form a fixed connection end, while the other end of the pressing block 53 is not fixed, forming a suspended and movable free end. Exemplarily, the pressing block 53 and the adapter housing can be an integrated structure to provide higher connection stability and simplify the connection structure between the pressing block 53 and the adapter housing. Alternatively, the connection end of the pressing block 53 can also be fixed to the adapter housing by welding or other methods.

[0077] When the user presses the pressing part 52 in the pressing direction, the free end of the pressing block 53 is squeezed by the pressing part 52, and then moves in the pressing direction until the button 51 is triggered to generate an electrical signal. Furthermore, due to the movement of the free end of the pressing block 53, the pressing block 53 deforms and stores the energy generated by the deformation. After the pressing part 52 loses its pressing force, the energy stored in the deformation of the pressing block 53 is released, which can drive the pressing part 52 and the pressing block 53 to move away from the button 51, thus achieving a reset. The reset state of the button assembly 50 can also be called the initial state or the non-working state. In this state, the pressing block 53 is separated from the button 51.

[0078] In this embodiment, the cantilever structure design increases the travel range of the button assembly 50, facilitating better design and installation of the button 51, improving the accuracy of the electrical signal generated by pressing the button 51, and reducing accidental touches caused by slight contact. Simultaneously, the cantilever structure also provides greater elasticity, enhancing the pressing feedback force of the button assembly 50 and improving the user's pressing experience.

[0079] Furthermore, in some embodiments, along the thickness direction of the housing portion 10, when the headphones are worn, the connecting end of the pressing block 53 is closer to the human body than the free end. This arrangement allows the free end of the pressing block 53 to be positioned further outwards from the adapter portion 20, and the corresponding pressing portion 52 to be positioned further outwards from the adapter portion 20, making it easier for the user to access and press the button assembly 50. Moreover, since the adapter portion 20 is bent along the long axis of the housing portion 10, and the pressing block 53 extends along the thickness direction of the housing portion 10, a longer cantilever can be provided. Increasing the length of the cantilever can improve the elasticity of the pressing block 53 and enhance the pressing feel; simultaneously, increasing the length of the cantilever can also increase the travel of the pressing block 53, improving the accuracy of the pressing block 53 in triggering the button 51 and avoiding errors caused by light touches.

[0080] Please refer to Figure 8In some embodiments, the adapter 20 further includes an outer layer 21, and the pressing part 52 can be a part of the outer layer 21. The outer layer 21 and the pressing part 52 are integrally formed, eliminating seams and improving the sealing within the adapter 20, resulting in better waterproofing and dustproofing. Furthermore, this allows for a smoother transition on the outer surface of the adapter 20, eliminating seams and enhancing the aesthetics of the headphones. For example, the outer layer 21 covers the outside of the adapter housing (e.g., the outer layer 21 can be connected to the adapter housing by adhesive, snap-fit, or other methods; or, for example, the outer layer 21 can be integrally injection molded onto the outside of the adapter housing). The Shore hardness of the outer layer 21 is lower than that of the adapter 20. For example, the outer layer 21 can be made of silicone or rubber, while the adapter 20 can be made of a relatively hard plastic material or other insulating material. This configuration gives the adapter 20 a relatively hard texture, stabilizing its contour and providing structural support for the installation of components such as the button assembly 50 and the circuit board. The outer layer 21 is relatively soft and can come into contact with human skin when the headphones are worn, thus effectively improving the comfort of wearing the headphones. The combination of soft and hard materials also facilitates the disassembly and maintenance of the adapter 20 and its related components, and enhances the stability of the structural connection between the adapter 20, the housing 10, and the ear hook 30.

[0081] Please refer to Figure 3 and Figure 4 In some embodiments, the ear hook portion 30 includes an ear hook cover, and the outer layer 21 of the adapter portion 20 is integrally formed with the ear hook cover of the ear hook portion 30. For example, the outer layer 21 and the ear hook cover are an integral structure made of silicone material. With this configuration, based on the integral structure of the outer layer 21 and the ear hook cover, the integrity of the outline structure of the ear hook portion 30 and the adapter portion 20 can be ensured, while improving the waterproof performance of the adapter portion 20.

[0082] Please refer to Figure 8 In some embodiments, the first accommodating cavity 10a of the housing portion 10 and the third accommodating cavity 20a of the adapter portion 20 are independently arranged. A separator may be provided within the adapter portion 20 to separate the first accommodating cavity 10a of the housing portion 10 and the third accommodating cavity 20a of the adapter portion 20. This arrangement isolates the speaker 40 installed in the first accommodating cavity 10a and the button assembly 50 installed in the third accommodating cavity 20a from each other. On the one hand, this avoids or reduces electromagnetic interference between the speaker 40 and the button assembly 50, ensuring the audio output quality of the speaker 40; on the other hand, the sealing of the separator improves the waterproof capability of the button assembly 50 in the third accommodating cavity 20a.

[0083] The adapter 20 may be provided with a partition that is integral with the adapter 20; or, the adapter 20 may be provided with a partition that is sealed and installed, for example, the mounting part of the button assembly 50 in the adapter 20 is sealed and connected to the adapter 20 to form a partition.

[0084] Please refer to Figure 10 In some embodiments, the circuit board 60 is located outside the housing portion 10, for example, within the second receiving cavity 30a of the ear hook portion 30. This arrangement means the circuit board 60 does not occupy space within the housing portion 10, freeing up more space to accommodate a larger speaker 40, thus improving the headphone's audio performance. Furthermore, the circuit board 60 does not occupy space within the adapter portion 20, allowing more space in the adapter portion 20 to accommodate other functional components, such as the button assembly 50 and a microphone.

[0085] Specifically, both the battery 90 and the circuit board 60 are located within the second accommodating cavity 30a. The battery 90 and circuit board 60 can be installed side-by-side along the length of the ear hook portion 30. For example, the circuit board 60 can be installed at the end of the second accommodating cavity 30a closer to the end of the ear hook portion 30, and the battery 90 at the end of the second accommodating cavity 30a away from the end of the ear hook portion 30. This arrangement fully utilizes the space along the length of the second accommodating cavity 30a of the ear hook portion 30. Furthermore, the circuit board 60 is closer to the speaker 40, resulting in a shorter circuit connection path between the circuit board 60 and the speaker 40, which reduces signal transmission damage and ensures signal transmission stability.

[0086] The circuit board 60 is electrically connected to both the battery 90 and the speaker 40. For example, the circuit board 60 can be electrically connected to the battery 90 and the speaker 40 via wires or flexible flat cables. The circuit board 60 controls the speaker 40 to play audio, and the battery 90 powers the entire headset.

[0087] In this embodiment, since the circuit board 60 is located in the second receiving cavity 30a at the end of the ear hook portion 30 away from the housing portion 10, and the speaker 40 is located in the first receiving cavity 10a of the housing portion 10, the circuit board 60 does not occupy the volume space of the first receiving cavity 10a within the housing portion 10. This allows a larger speaker 40 to be installed within the first receiving cavity 10a of the housing portion 10, thereby improving acoustic output. For example, a larger installation space allows the speaker 40 to use a larger magnetic circuit assembly, resulting in enhanced driving force and increased acoustic output. Therefore, by having the circuit board 60 located in the second receiving cavity 30a of the ear hook portion 30, a larger speaker 40 can be installed within the first receiving cavity 10a of the housing portion 10, thus improving the sound quality of the headphones.

[0088] It should be noted that: the circuit board 60 is not located in the first accommodating cavity 10a, and the first accommodating cavity 10a is not provided with a circuit board. The circuit board refers to a circuit board with control and processing functions. The first accommodating cavity 10a may be provided with necessary components such as a flexible circuit board (flexible flat cable) or wires for electrical connection.

[0089] In this embodiment, the circuit board 60 is located within the second accommodating cavity 30a of the ear hook portion 30. The circuit board 60 and the speaker 40 are relatively far apart and separated, which can reduce the electromagnetic interference between the circuit board 60 and the speaker 40 and improve the playback sound quality of the headphones. When the headphones are worn, the housing portion 10 and the speaker 40 inside it are located in front of the ear (at the concha), and the end of the ear hook portion 30 and the circuit board 60 inside it are located behind the ear (at the back of the ear). The speaker 40 and the circuit board 60 are isolated by the ear, and there is also an isolation effect between the speaker 40 and the circuit board 60, which can further reduce the electromagnetic interference between the circuit board 60 and the speaker 40 and further improve the playback sound quality of the headphones.

[0090] Please refer to Figure 8 and Figure 11 In some embodiments, the headphones also include an adapter circuit board 70, through which the circuit board 60 is electrically connected to components such as the speaker 40 and the button assembly 50. The adapter circuit board 70 is disposed within the adapter portion 20, and serves as a transitional electrical connection. The adapter circuit board 70 also facilitates the circuit installation of the circuit board 60 with components such as the speaker 40 and the button assembly 50.

[0091] In this embodiment, the adapter circuit board 70 is used for connecting circuits. The adapter circuit board 70 does not have processing or control functions; for example, the adapter circuit board 70 is a flexible flat cable. This design not only reduces the cost of the adapter circuit board 70, but the flexibility of the adapter circuit board 70 also facilitates the connection and installation between lines. In other embodiments, the adapter circuit board 70 may also have some processing and control functions.

[0092] In this embodiment, the adapter circuit board 70 is located within the third accommodating cavity 20a of the adapter portion 20. This arrangement allows the adapter circuit board 70 to fully utilize the space of the third accommodating cavity 20a of the adapter portion 20. Furthermore, the adapter circuit board 70 is close to the speaker 40, enabling docking installation with the speaker 40. For example, the adapter circuit board 70 has a first plug terminal, and the speaker 40 has or is connected to a second plug terminal. One of the first and second plug terminals is a socket, and the other is a plug. The first and second plug terminals are electrically connected, facilitating the electrical connection and installation between the adapter circuit board 70 and the speaker 40.

[0093] In this embodiment, the adapter circuit board 70 and the circuit board 60 can be electrically connected via electrical connectors, such as wires. The wires 80 include multiple independent wires 80 to transmit different signals. This configuration allows the wires 80 to have a smaller volume compared to electrical connectors such as flexible flat cables, enabling multiple wires 80 to pass through the smaller ear loop portion 30. The middle portions of the multiple independent wires 80 can be combined into a cylinder to form a wire post, facilitating their insertion into the ear loop portion 30. Their ends can be dispersed to achieve side-by-side or separate fixing, thus meeting the respective electrical connection requirements of the adapter circuit board 70 and the circuit board 60.

[0094] Specifically, the ear hook portion 30 has a wire hole. One end of the wire hole communicates with the second receiving cavity 30a within the ear hook portion 30, and the other end communicates with the third receiving cavity 20a within the adapter portion 20. A wire 80 passes through the wire hole. One end of the wire 80 extends into the second receiving cavity 30a and is electrically connected to the circuit board 60, while the other end extends into the third receiving cavity 20a and is electrically connected to the adapter circuit board 70. The wire 80 can also be directly molded into the ear hook portion 30 using injection molding or similar methods. Both ends of the wire 80 can be fixedly connected to the circuit board 60 and the adapter circuit board 70 respectively by soldering or other methods, thus forming an electrical connection.

[0095] In this embodiment, since an adapter circuit board 70 is provided in the adapter part 20, the circuit board 60 located in the ear hook part 30 is connected to the speaker 40 located in the housing part 10 through the adapter circuit board 70. The ear hook part 30 and the adapter part 20 can be initially installed as a combined component. After the ear hook part 30 and the adapter part 20 are installed and fixed, the circuit board 60 first establishes an electrical connection with the adapter circuit board 70, and then the adapter part 20 is connected to the housing part 10. With this arrangement, the electrical connection between the speaker 40 and the circuit board 60, which are relatively far apart, can be transformed into a connection between the speaker 40 and the adapter circuit board 70, which are relatively close, thus simplifying the installation difficulty of the electrical connection.

[0096] In some embodiments, the adapter circuit board 70 is also used to connect other functional components besides the speaker 40. For example, the adapter circuit board 70 is electrically connected to the button assembly 50, or the adapter circuit board 70 is electrically connected to the microphone 100. With this configuration, the adapter circuit board 70 can not only provide a transitional connection between the speaker 40 and the circuit board 60, but can also be used to expand the connection of other functional components of the headphones, thereby increasing the functionality of the headphones.

[0097] In this circuit, button 51 of button assembly 50 is electrically connected to adapter circuit board 70, and button assembly 50 is electrically connected to circuit board 60 through adapter circuit board 70 to transmit the electrical signal generated by button assembly 50 to circuit board 60.

[0098] Please refer to Figure 8In some embodiments, the button 51 of the button assembly 50 is directly mounted on the adapter circuit board 70, and the button 51 is perpendicular to the adapter circuit board 70. With this configuration, the adapter circuit board 70 and the pressing direction of the button 51 are parallel, and the force transmitted from the button 51 to the adapter circuit board 70 does not have a component that is tilted relative to the adapter circuit board 70. This allows the adapter circuit board 70 to provide more stable support for the pressing of the button assembly 50, improving the stability of the button assembly 50's pressing operation.

[0099] Please refer to Figure 8 The adapter circuit board 70 may include a first adapter circuit board 71, which is a flat plate structure. The first adapter circuit board 71 may be a combination of a flexible circuit board and a support plate structure, or a rigid circuit board structure. The first adapter circuit board 71 is located in the third accommodating cavity 20a of the adapter part 20, and the first adapter circuit board 71 may be fixedly connected to the adapter part 20 through a structure such as a mounting base.

[0100] The button 51 of the button assembly 50 has an approximately flat structure. The button 51 is fixed to the end side of the first adapter circuit board 71. The button 51 is perpendicular to the first adapter circuit board 71, and the central axis of the button assembly 50 is parallel or coincident with the first adapter circuit board 71. That is, the pressing direction of the button assembly 50 is parallel or coincident with the first adapter circuit board 71.

[0101] In this embodiment, button 51 and the first adapter circuit board 71 can be directly fixed together by means of snap-fit, soldering, or other methods. In other embodiments, button 51 can also be mounted on the first adapter circuit board 71 by means of a mounting bracket or other components, which can also keep button 51 perpendicular to the first adapter circuit board 71.

[0102] Please refer to Figure 8 In some embodiments, the adapter circuit board 70 includes multiple circuit boards that can be stacked on top of each other and can also be tilted relative to each other. For example, the adapter circuit board 70 includes two circuit boards connected in series, and the button 51 is electrically connected to one of the circuit boards. This arrangement allows for the installation of a larger area or volume adapter circuit board 70 within the limited third accommodating cavity 20a of the adapter portion 20, enabling the adapter circuit board 70 to connect more functional components. The tilted adapter circuit boards can be correspondingly arranged along the curved third accommodating cavity 20a to fully utilize the space within the third accommodating cavity 20a of the adapter portion 20. Furthermore, the adapter circuit board connected to the button 51 is tilted parallel to the button direction to provide stable support for pressing.

[0103] Specifically, the adapter circuit board 70 includes a first adapter circuit board 71 and a second adapter circuit board 72, which are stacked and spaced apart within the third accommodating cavity 20a of the adapter portion 20. The circuit board 60, the first adapter circuit board 71, the second adapter circuit board 72, and the speaker 40 are sequentially electrically connected, with the first and second adapter circuit boards 71 ​​and 72 serving as adapters for the speaker 40. In other embodiments, the second adapter circuit board 72 can also be used to connect other functional components such as a microphone 100.

[0104] The first adapter circuit board 71 and the second adapter circuit board 72 can be tilted relative to each other, and the tilting direction of the first adapter circuit board 71 and the second adapter circuit board 72 is adapted to the bending direction of the third accommodating cavity 20a. For example, the tilting angle between the first adapter circuit board 71 and the second adapter circuit board 72 is 0-45°. Specifically, the distance between the ends of the first adapter circuit board 71 and the second adapter circuit board 72 near the upper side 20d of the adapter portion 20 is smaller than the distance between the other ends of the first adapter circuit board 71 and the second adapter circuit board 72 near the lower side 20e of the adapter portion 20, so that the first adapter circuit board 71 and the second adapter circuit board 72 can make more full use of the curved third accommodating cavity 20a to install a larger area adapter circuit board 70.

[0105] Please refer to Figure 8 In some embodiments, the second adapter circuit board 72 is positioned closer to the speaker 40 than the first adapter circuit board 71, and the second adapter circuit board 72 can be positioned parallel to the end face facing the speaker 40, with the second adapter circuit board 72 perpendicular to the long axis direction of the housing portion 10. This arrangement reduces the spatial gap between the second adapter circuit board 72 and the speaker 40, which helps to shorten and reduce the overall size of the adapter portion 20, achieving miniaturization of the adapter portion 20. The parallel arrangement of the second adapter circuit board 72 with the speaker 40 allows the second adapter circuit board 72 to have a plug-in portion mounted along the long axis direction, improving the convenience of plug-in connection between the second adapter circuit board 72 and the speaker 40. Furthermore, the second adapter circuit board 72 can form part of the internal partition of the adapter portion 20 to separate the third accommodating cavity 20a and the first accommodating cavity 10a, improving the waterproofness of the third accommodating cavity 20a within the adapter portion 20.
