[0053] The present application will be further described below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are intended only to illustrate the present application and are not intended to limit the scope of the present application. Similarly, the following examples are only some examples of the present application and are not intended to be exhaustive. All other examples obtained by persons of ordinary skill in the art without creative effort are intended to fall within the scope of protection of this application.

[0054] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0055] In the present application, the electronic device 10 can be a terminal device with a sound-generating function, such as headphones and smart glasses. The electronic device 10 may include a core module 11 and a support assembly 12, and the support assembly 12 may be connected to the core module 11 to support the core module 11 to be worn in the wearing position. The core module 11 may generate mechanical vibrations under the action of an excitation signal, and the aforementioned mechanical vibrations may be transmitted to the user based on at least one of bone conduction and air conduction. Further, in conjunction with FIG1 , the support assembly 12 may be configured to support the user's ears in the worn state, and further be arranged around the back of the user's head. There may be two core modules 11, and the two core modules 11 are connected to the two ends of the support assembly 12 one by one. Of course, in some other embodiments, the support assembly 12 may also be configured to support the user's ears and nose bridge and other physiological parts in the worn state, and may also be configured to pass around the top of the user's head in the worn state, which are not listed here one by one. Based on this, the aforementioned wearing position can be the position of the user's cheek close to the ear, a position on the side of the ear away from the head, or other physiological parts, which are not listed here one by one.

[0056] As an example, referring to Figures 2 and 3 , the movement module 11 may include a housing assembly 111, a transducer 112, and a vibration panel 113. The transducer 112 is configured to generate mechanical vibrations in response to an excitation signal and is disposed within the housing assembly 111; the vibration panel 113 is connected to the transducer 112 and is configured to indirectly abut or directly contact the user's skin to transmit the mechanical vibrations.

[0057] Furthermore, the movement module 11 may include a face-sticking component 114 connected to at least the vibration panel 113, for example, the face-sticking component 114 covers the vibration panel 113, so that the vibration panel 113 is in contact with the user's skin through the face-sticking component 114, so as to take into account the sound quality and wearing comfort of the electronic device 10.

[0058] As an example, in combination with Figures 2 and 3, the movement module 11 may include a first vibration transmitting plate 115, and the transducer device 112 may be connected to the housing assembly 111 through the first vibration transmitting plate 115. In this way, compared with the transducer device 112 being directly fixed in the housing assembly 111, this is conducive to avoiding excessive transmission of mechanical vibrations generated by the transducer device 112 to the housing assembly 111, thereby helping to reduce sound leakage of the movement module 11. Among them, the transducer device 112 may include a bracket 1121, a second vibration transmitting plate 1122, a magnetic circuit system and a coil 1123, the bracket 1121 may be connected to the housing assembly 111 through the first vibration transmitting plate 115, the aforementioned magnetic circuit system may be connected to the bracket 1121 through the second vibration transmitting plate 1122, the coil 1123 is connected to the bracket 1121, and extends into the magnetic gap of the aforementioned magnetic circuit system. Thus, under the action of the excitation signal, the energized coil 1123 generates an Ampere force in the magnetic field of the aforementioned magnetic circuit system, causing the bracket 1121 to move relative to the aforementioned magnetic circuit system, thereby generating mechanical vibration. Furthermore, the aforementioned magnetic circuit system may include a magnetic shield 1124 and a magnet 1125. The magnet 1125 may be fixed to the bottom of the magnetic shield 1124 and form the aforementioned magnetic gap between the side wall of the magnetic shield 1124. The number of magnets 1125 may be one or more, such as the two shown in Figures 2 and 3. Two adjacent magnets 1125 are arranged with the same poles facing each other, and a magnetic plate may be sandwiched between them to allow the magnetic flux lines of the magnets 1125 to pass through the coil 1123 more frequently. In some embodiments, the magnetic circuit system may include a fastener 1126. The fastener 1126 can secure the stacked plurality of magnets 1125 and the magnetic plate sandwiched between the magnets 1125, for example, connecting the second vibration transmission plate 1122, the magnet 1125, and the bottom of the magnetic shield 1124. Of course, in some other embodiments, the magnet 1125 can be fixed to the bottom of the magnetic cover 1124 by glue.

[0059] As an example, in conjunction with Figures 2 and 3, the face-sticking assembly 114 may include a face-sticking cover 1141, which may cover the vibration panel 113. For example, the face-sticking cover 1141 is connected to the vibration panel 113 via an adhesive medium 1142, which is beneficial to increasing the flatness of the face-sticking cover 1141 on the vibration panel 113 and increasing the synchronization between the face-sticking cover 1141 and the vibration panel 113 during the vibration process. Among them, the adhesive medium 1142 can be configured to allow the face-sticking assembly 114 to be removed from the vibration panel 113 as a whole without damaging the face-sticking assembly 114 and the vibration panel 113. In this way, the face-sticking assembly 114 is not only detachable, making it easy for the user to replace it with a new one when needed, but also avoids breakage because it can be removed as a whole, which is beneficial to reducing the difficulty of removing the face-sticking assembly 114 from the movement module 11, thereby improving the portability of replacing the face-sticking assembly 114.

[0060] By way of example, the adhesive medium 1142 can be configured to ensure that the peeling force between the face cover 1141 and the vibration panel 113 is between 4 N and 12 N. If the peeling force is too small, i.e., the adhesive force is too small, the face cover 1141 may not be flat enough on the vibration panel 113 and may not be synchronized well with the vibration panel 113 during vibration. If the peeling force is too large, i.e., the adhesive force is too large, the face cover 1141 may be difficult to remove from the vibration panel 113 as a whole.

[0061] As an example, the peeling force between the adhesive medium 1142 and the face cover 1141 can be greater than the peeling force between the adhesive medium 1142 and the vibration panel 113. In this way, when the face cover 1141 is removed from the vibration panel 113, the adhesive medium 1142 is more likely to be peeled off along with the face cover 114 rather than remaining on the vibration panel 113. This reduces the risk of adhesive residue on the vibration panel 113, making it easier to replace the face cover 114. The material of the adhesive medium 1142 is preferably similar to that of the face cover 1141 to increase the bonding strength between the adhesive medium 1142 and the face cover 1141.

[0062] As an example, the bonding medium 1142 can be a double-sided tape or a cured glue. The adhesive layers on both sides of the double-sided tape can be designed differently according to the materials of the face cover 1141 and the vibration panel 113, and the material of the glue can also be selected to be a glue material similar to the material of the face cover 1141. Furthermore, the hardness of the face cover 1141 can be less than the hardness of the vibration panel 113, and the hardness of the bonding medium 1142 can also be less than the hardness of the vibration panel 113. The material of the vibration panel 113 can be polycarbonate or at least one of glass fiber and carbon fiber mixed therein, and the material of the face cover 1141 can be silicone, rubber, etc. Therefore, the glue can be a silicone soft glue.

[0063] As an example, the ratio between the area of ​​the bonding medium 1142 and the area of ​​the vibration panel 113 can be between 0.8 and 1, for example, the bonding medium 1142 covers the entire vibration panel 113 (commonly known as "full bonding"), and for another example, the bonding medium 1142 is in a grid shape. If the aforementioned ratio is too small, it is easy to cause the face cover 1141 to be insufficiently flat on the vibration panel 113 and its synchronization with the vibration panel 113 during the vibration process is poor. It is worth noting that: the area of ​​the face cover 1141 is generally larger than the area of ​​the vibration panel 113. If the area of ​​the bonding medium 1142 is larger than the area of ​​the vibration panel 113, then the area of ​​the portion of the bonding medium 1142 that is not in contact with the vibration panel 113 is not counted as the area of ​​the bonding medium 1142. Furthermore, the ratio between the thickness of the bonding medium 1142 and the thickness of the face cover 1141 can be between 0.4 and 1.2. If the aforementioned ratio is too small, the bonding force provided by the bonding medium 1142 may be insufficient. If the aforementioned ratio is too large, the mechanical vibration generated by the transducer 112 may be excessively lost during transmission through the face cover 1141 and the bonding medium 1142. Furthermore, the thickness of the bonding medium 1142 may be less than the thickness of the face cover 1141. It is worth noting that in embodiments where the thickness of a portion of the face cover 1141 connected to the vibration panel 113 via the bonding medium 1142 is not equal to the thickness of another portion of the face cover 1141 not connected to the vibration panel 113, when calculating the ratio or magnitude relationship between the thickness of the bonding medium 1142 and the thickness of the face cover 1141, the thickness of the face cover 1141 may specifically refer to the thickness of the portion of the face cover 1141 connected to the vibration panel 113 via the bonding medium 1142 (e.g., the main body 11411 described below).

[0064] It should be noted that the electronic device 10 can include several pairs of face-mounted assemblies 114, allowing the user to easily replace them when needed. The adhesive medium 1142 can be pre-fixed to the face-mounted cover 1141, meaning that the adhesive medium 1142 and the face-mounted cover 1141 are integrated. Release paper can be provided on the side of the adhesive medium 1142 that bonds to the vibration panel 113 to maintain the adhesiveness of the adhesive medium 1142. When replacing a new face-mounted assembly 114, the user can simply tear off the release paper. Of course, in other embodiments, the adhesive medium 1142 can also be independent of the face-mounted cover 1141.

[0065] As an example, in conjunction with Figures 2 to 4, the face-fitting component 114 may include a reinforcing piece 1143 connected to the face-fitting cover 1141, and the hardness of the reinforcing piece 1143 is greater than the hardness of the face-fitting cover 1141, so as to increase the local structural strength of the face-fitting component 114. For example: the material of the face-fitting cover 1141 is silicone, rubber, etc., and the material of the reinforcing piece 1143 is polycarbonate or at least one of glass fiber and carbon fiber is mixed therein, and the two are formed into an integrally molded structural component through an injection molding process. Among them, the face-fitting component 114 can be detachably connected to the shell component 111 through the reinforcing piece 1143 to prevent the edge area of ​​the face-fitting component 114 from colliding with the shell component 111 when the face-fitting component 114 vibrates in accordance with the vibration panel 113. In other words, the middle area and the edge area of ​​the face-fitting component 114 can be detachably connected to the vibration panel 113 and the shell component 111, respectively. Accordingly, the face assembly 114 and the housing assembly 111 enclose a cavity that accommodates at least the transducer 112 and the vibration panel 113. Of course, in other embodiments, such as where a sufficiently large safety gap exists between the edge of the face cover 1141 and the housing assembly 111, the face assembly 114 may not include the reinforcement 1143, and the edge of the face cover 1141 may therefore not be connected to the housing assembly 111. Furthermore, in other embodiments, such as where the face assembly 114 does not need to be replaced, the face assembly 114 may be configured to be non-removable.

[0066] In some embodiments, the housing assembly 111 may include a core housing 1111, one end of which is open. The transducer 112 may be at least partially located within the core housing 1111, and the vibration panel 113 may be at least partially located outside the core housing 1111. The reinforcement 1143 may be at least partially located within the open end of the core housing 1111 and may be detachably connected to the core housing 1111, thereby ensuring a certain degree of bonding between the face-mounting assembly 114 and the housing assembly 111.

[0067] In some embodiments, the housing assembly 111 may include a movement housing 1111 and a movement cover plate 1112 covering the open end of the movement housing 1111. The transducer 112 may be at least partially located inside the movement housing 1111, and the vibration panel 113 may be at least partially located outside the movement housing 1111. That is, the face-mounted assembly 114 and the transducer 112 may be located on opposite sides of the movement cover plate 1112, respectively. Accordingly, the movement cover plate 1112 is provided with a first avoidance hole 11121 that allows the vibration panel 113 to be connected to the transducer 112. The reinforcement member 1143 may be at least partially located outside the movement housing 1111 and may be detachably connected to the movement cover plate 1112, so that a certain bonding force exists between the face-mounted assembly 114 and the housing assembly 111.

[0068] Furthermore, the transducer 112 and the bottom of the movement housing 1111 can be spaced apart in the vibration direction of the transducer 112 (e.g., the direction indicated by arrow D1 in FIG3 ) to reduce the risk of collision between the transducer 112 and the bottom of the movement housing 1111 during vibration. In some embodiments, the transducer 112 and the bottom of the movement housing 1111 can be spaced apart in the vibration direction of the transducer 112 within a certain threshold range, thereby ensuring that the thickness of the movement housing 1111 meets the requirements while maintaining the movement module 11 under extreme operating conditions such as falling or collision.

[0069] As an example, in conjunction with Figures 5 to 8 , one of the open end of the movement housing 1111 and the flange portion 11432 can be provided with a snap protrusion 11111, and the other can be provided with a snap recess 11434 for accommodating the snap protrusion 11111. The snap protrusion 11111 fits within the snap recess 11434, thereby enabling the combination of the two to achieve a simple and reliable detachable connection between the reinforcement member 1143 and the movement housing 1111. The number of snap protrusions 11111 can be multiple, such as the four shown in Figure 8 ; the number of snap recesses 11434 can be equal to the number of snap protrusions 11111, such as the four shown in Figure 6 , and can correspond one to one.

[0070] As an example, in conjunction with Figures 5 and 6 , the reinforcement piece 1143 may include an annular main portion 11431 and a flange portion 11432 connected to the annular main portion 11431. The face cover 1141 may be connected to at least the annular main portion 11431, for example, by injection molding. The number of flange portions 11432 may be multiple, such as the four shown in Figure 6 , with the multiple flange portions 11432 spaced apart circumferentially around the annular main portion 11431. Accordingly, the flange portion 11432 is detachably connected to the movement housing 1111, thereby achieving detachable connection between the reinforcement piece 1143 and the movement housing 1111. Furthermore, the reinforcement piece 1143 may include a raised portion 11433 connected to the annular main portion 11431, and the face cover 1141 may be further connected to the raised portion 11433, which helps to increase the connection area between the face cover 1141 and the reinforcement piece 1143, thereby increasing the bonding strength between the two. The number of raised portions 11433 may be multiple, such as eight as shown in FIG6 , and the multiple raised portions 11433 may be spaced apart circumferentially around the annular main portion 11431, for example, the multiple flange portions 11432 and the multiple raised portions 11433 may be alternately spaced apart circumferentially around the annular main portion 11431.

[0071] Furthermore, the ratio of the covering area of ​​the reinforcement 1143 by the face cover 1141 to the surface area of ​​the reinforcement 1143 can be greater than or equal to 0.8. For example, the annular main body 11431 and the raised portion 11433 are all covered by the face cover 1141 to increase the connection area between the face cover 1141 and the reinforcement 1143 as much as possible.

[0072] As an example, in conjunction with Figures 2 and 3, 5, and 6, the face cover 1141 may include an integrally connected main body 11411, a transition portion 11412, and a covering portion 11413. The main body 11411 and the covering portion 11413 may be staggered with respect to the vibration direction D1. The orthographic projection of the covering portion 11413 on a reference plane perpendicular to the vibration direction D1 surrounds the orthographic projection of the main body 11411 on the aforementioned reference plane, that is, the covering portion 11413 is located on the periphery of the main body 11411, and the transition portion 11412 connects the main body 11411 and the covering portion 11413. The main body 11411 may be connected to the vibration panel 113 via a bonding medium 1142, and the covering portion 11413 may cover the reinforcement member 1143, for example, at least the annular main body 11431. Furthermore, the covering portion 11413 can be closer to the transducer 112 than the main body 11411 in the vibration direction D1, so that the vibration panel 113 can contact the user's skin through the main body 11411. In addition, in embodiments where the face cover 1141 is provided with a connecting hole 11414, for example, the connecting hole 11414 is provided on the transition portion 11412, which also helps prevent the connecting hole 11414 from being covered by the user's skin.

[0073] Furthermore, on a reference cross-section (e.g., a paper surface) parallel to the vibration direction D1, the transition portion 11412 can be curved to increase the deformation capacity of the transition portion 11412, which helps prevent the vibration of the vibration panel 113 from being restricted by the housing assembly 111, especially in embodiments where the middle region and edge regions of the face-mounted assembly 114 are respectively connected to the vibration panel 113 and the housing assembly 111. Specifically, in the direction extending from the main body 11411 to the covering portion 11413, the transition portion 11412 can first gradually approach the transducer 112 and then gradually move away from the transducer 112, or the transition portion 11412 can first gradually approach the transducer 112 and then become parallel to the plane where the first vibration transmission plate 115 is located.

[0074] As an example, the movable margin of the transition portion 11412 in the vibration direction D1 may be greater than or equal to the maximum amplitude of the transducer 112. The movable margin may refer to the displacement of the transition portion 11412 when it changes from a curved shape to a straight shape.

[0075] By way of example, in conjunction with Figures 2 and 3, and Figures 5 to 8, the open end of the movement housing 1111 may be provided with a communication hole 11112. The communication hole 11112 is located between two adjacent flange portions 11432 in the circumferential direction of the annular main body portion 11431. The communication hole 11112 communicates with the inside and outside of the movement module 11 via the passage between the two corresponding flange portions 11432. Since the number of flange portions 11432 can be multiple, such as four as shown in Figure 6, the number of communication holes 11112 can also be multiple, such as four as shown in Figures 7 and 8. That is, the communication holes 11112 can correspond one-to-one to the aforementioned passages. In this way, although the movement shell 1111 generally forms a first sound leakage in the far field under the driving action of the transducer device 112, the air in the cavity formed by the face assembly 114 and the shell assembly 111 forms a second sound leakage in the far field under the action of the transducer device 112 and through the connecting hole 11112 and the aforementioned channel, and the phase of the aforementioned second sound leakage and the phase of the aforementioned first sound leakage are (close to) opposite to each other. For example, the difference between the absolute value of the phase of the aforementioned second sound leakage and the absolute value of the phase of the aforementioned first sound leakage is less than 60°, so that the two can cancel each other out of phase in the far field, which is beneficial to reducing the sound leakage of the movement module 11 in the far field. It is worth noting that the connecting hole 11112 can be a complete through hole on the open end of the movement shell 1111, or it can be a notch on the open end of the movement shell 1111.

[0076] Furthermore, the face cover 1141 may be provided with a connecting hole 11414, for example, the connecting hole 11414 is provided on the transition portion 11412. The function of the connecting hole 11414 is the same as or similar to that of the connecting hole 11112, and will not be repeated here. It is worth noting that: in an embodiment in which only the connecting hole 11112 is provided to reduce the sound leakage of the movement module 11 in the far field, the face cover 1141 may also not be provided with the connecting hole 11414, which is conducive to preventing sweat and the like from invading the electronic device 10. Similarly, in an embodiment in which only the connecting hole 11414 is provided to reduce the sound leakage of the movement module 11 in the far field, the open end of the movement shell 1111 may also not be provided with the connecting hole 11112 to simplify the structure of the movement shell 1111.

[0077] The inventors of this application discovered during a long period of research and development that: although the above-mentioned second sound leakage is beneficial to reducing the sound leakage of the movement module 11 in the far field, the frequency response curve of the above-mentioned second sound leakage is relatively disordered, which leaves it with a certain amount of room for optimization. To this end, in conjunction with Figures 2 and 3, the shell assembly 111 may include a movement cover plate 1112 covering the open end of the movement shell 1111, the face assembly 114 and the transducer 112 may be respectively located on opposite sides of the movement cover plate 1112, and the movement cover plate 1112 is provided with a first avoidance hole 11121 that allows the vibration panel 113 to be connected to the transducer 112. The movement cover 1112 can divide the cavity formed by the face assembly 114 and the housing assembly 111 into two, that is, the movement cover 1112 and the movement housing 1111 cooperate to form a first cavity, and the face assembly 114 and the housing assembly 111 cooperate to form a second cavity. For example, the first cavity and the second cavity are respectively located on opposite sides of the movement cover 1112. Furthermore, the transducer 112 can be at least partially located in the first cavity, and the vibration panel 113 can be at least partially located in the second cavity. Correspondingly, the movement module 11 is provided with a channel connecting the aforementioned second cavity and the outside of the movement module 11, so as to allow the air in the aforementioned first cavity to form a third sound leakage in the far field under the action of the transducer 112 and through the aforementioned channel, and the phase of the aforementioned third sound leakage and the phase of the aforementioned first sound leakage are (close to) opposite to each other. For example, the difference between the absolute value of the phase of the aforementioned third sound leakage and the absolute value of the phase of the aforementioned first sound leakage is less than 60°, so that the two can cancel each other out of phase in the far field, which is beneficial to reducing the sound leakage of the movement module 11 in the far field. In this way, under the restrictive effect of the movement cover 1112, the air in the aforementioned first cavity can be restricted to enter and exit the movement module 11 to a certain extent, which is beneficial to avoid the frequency response curve of the sound leakage that cancels out phase with the aforementioned first sound leakage in the far field being too disordered, thereby increasing the sound leakage reduction effect of the movement module 11. Based on the Helmholtz resonance cavity, the area of ​​the aforementioned channel can be as large as possible, for example, by increasing the number of the aforementioned channels, or by increasing the aperture of each of the aforementioned channels, so that the resonant frequency of the aforementioned third leakage sound is shifted to a higher frequency band (for example, a frequency range greater than 4kHz) as much as possible, which is beneficial to further prevent the aforementioned third leakage sound from being heard by the user.

[0078] As an example, the number of the aforementioned channels can be multiple, which is beneficial for increasing the area of ​​the aforementioned channels. Specifically, the aforementioned channels can all be provided on any one of the structural components, such as the face cover 1141, the reinforcement 1143, or the movement housing 1111. Alternatively, the aforementioned channels can be partially provided on one of the structural components, such as the face cover 1141, the reinforcement 1143, or the movement housing 1111, while the remaining channels can be provided on another structural component, such as the face cover 1141, the reinforcement 1143, or the movement housing 1111.

[0079] Furthermore, for any one of the above-mentioned channels, the above-mentioned channel can be formed by at least any one of the following embodiments.

[0080] In some embodiments, for example, if the reinforcement member 1143 is at least partially located within the open end of the movement housing 1111, the aforementioned channel may be at least partially disposed on the reinforcement member 1143. For example, the flange portion 11432 and the space between two adjacent flange portions 11432 are both located within the open end of the movement housing 1111. The space between two adjacent flange portions 11432 constitutes a portion of the aforementioned channel, and the connecting hole 11112 constitutes another portion of the same channel. For another example, the flange portion 11432 and the space between two adjacent flange portions 11432 are both located within the open end of the movement housing 1111. An assembly gap exists between the face assembly 114 and the movement housing 1111. The space between two adjacent flange portions 11432 constitutes a portion of the aforementioned channel, and the assembly gap between the face assembly 114 and the movement housing 1111 constitutes another portion of the same channel.

[0081] In some embodiments, for example, the reinforcement 1143 is at least partially located within the open end of the movement housing 1111, and the above-mentioned channel can be at least partially provided at the open end of the movement housing 1111. For example: the open end of the movement housing 1111 is provided with a connecting hole 11112, and the side of the face-mounted component 114 that contacts the movement cover plate 1112 is provided with an uneven surface, such as an undulating wavy surface, so that at least part of the reinforcement 1143 does not contact the movement cover plate 1112 to form a reserved gap. In addition, there is an assembly gap between the face-mounted component 114 and the movement housing 1111, and the reserved gap between the face-mounted component 114 and the movement cover plate 1112 and the assembly gap between the face-mounted component 114 and the movement housing 1111 constitute part of the above-mentioned channel, and the connecting hole 11112 constitutes another part of the same channel. For another example: the open end of the movement housing 1111 is provided with a connecting hole 11112, and there is an assembly gap between the face-mounted component 114 and the movement housing 1111 and the movement cover plate 1112. The connecting hole 11112 constitutes a part of the above-mentioned channel, and the assembly gap between the face-mounted component 114 and the movement housing 1111 and the movement cover plate 1112 constitutes another part of the same channel.

[0082] In some embodiments, the above-mentioned channel can be provided on the face cover 1141, for example, the connecting hole 11414 serves as the above-mentioned channel.

[0083] In some embodiments, for example, the reinforcement 1143 is at least partially located outside the open end of the movement shell 1111, and the above-mentioned channel can be only provided on the reinforcement 1143. For example, the spacing area between two adjacent flange portions 11432 is at least partially located outside the open end of the movement shell 1111, and the spacing area between two adjacent flange portions 11432 can serve as the above-mentioned channel.

[0084] In some embodiments, for example, the reinforcement 1143 is at least partially located within the open end of the movement housing 1111, and the above-mentioned channel can be at least partially provided at the open end of the movement housing 1111, for example, the connecting hole 11112 serves as the above-mentioned channel, and at least part of the reinforcement 1143 is not in contact with the movement cover 1112, so that the above-mentioned first cavity can be connected with the connecting hole 11112 via the gap between the reinforcement 1143 and the movement cover 1112.

[0085] As an example, with reference to FIG3 , the channel can be configured so that the direction of gas flow between the second cavity and the exterior of the movement module 11 (e.g., the direction indicated by arrow D2 in FIG3 ) intersects with the vibration direction D1. For example, the channel does not extend toward the side of the movement module 11 that faces the user's skin when worn. This helps prevent the channel from being covered by the user's skin, thereby allowing the third sound leakage and the first sound leakage to better cancel each other out of phase in the far field.

[0086] As an example, in conjunction with Figures 2 and 3, the movement cover plate 1112 may include an inner top 11122, a connecting portion 11123, and an outer bottom 11124 that are integrally connected. The inner top 11122 and the outer bottom 11124 are staggered with each other in the vibration direction D1. The orthographic projection of the outer bottom 11124 on a reference plane perpendicular to the vibration direction D1 surrounds the orthographic projection of the inner top 11122 on the aforementioned reference plane, that is, the outer bottom 11124 is located on the periphery of the inner top 11122, and the connecting portion 11123 connects the inner top 11122 and the outer bottom 11124. The outer bottom 11124 can be connected to the housing assembly 111. The outer bottom 11124 is closer to the transducer 112 than the inner top 11122 in the vibration direction D1, which helps to avoid the connecting hole 11112 on the movement housing 1111. Accordingly, in combination with FIG. 4 , the first avoidance hole 11121 may be provided on the inner top 11122 .

[0087] As an example, in conjunction with Figures 2 and 3, the housing assembly 111 may include a sealing film 1113 connected to the movement cover plate 1112, the sealing film 1113 is provided with a second avoidance hole 11131 that allows the vibration panel 113 to be connected to the transducer device 112, the aperture of the second avoidance hole 11131 is smaller than the aperture of the first avoidance hole 11121, and the sealing film 1113 is used to seal the assembly gap of the first avoidance hole 11121. The aforementioned assembly gap refers to the gap between the structure formed by the connection of the vibration panel 113 and the transducer device 112 and the hole wall surface of the first avoidance hole 11121, and the assembly gap can prevent the vibration panel 113 and / or the transducer device 112 from colliding with the movement cover plate 1112. In this way, under the restrictive effect of the movement cover 1112 and the sealing film 1113, the air in the above-mentioned first cavity can be restricted to the greatest extent from entering and exiting the movement module 11, which is beneficial to further avoid the frequency response curve of the leakage sound that is in anti-phase with the above-mentioned first leakage sound in the far field from being too disordered, thereby increasing the leakage sound reduction effect of the movement module 11. In addition, due to the provision of the sealing film 1113, the aperture of the first avoidance hole 11121 can be larger, which is beneficial to further avoid the aforementioned collision. Accordingly, the vibration panel 113 can be connected to the bracket 1121 via the second avoidance hole 11131 and the first avoidance hole 11112.

[0088] By way of example, in conjunction with Figures 2 to 4 , the sealing membrane 1113 may include an integrally connected first connecting portion 11132, a folding ring portion 11133, and a second connecting portion 11134, wherein the folding ring portion 11133 connects the first connecting portion 11132 and the second connecting portion 11134. The stiffness of the first connecting portion 11132 and the second connecting portion 11134 may be greater than the stiffness of the folding ring portion 11133. For example, the first connecting portion 11132 and the second connecting portion 11134 may be annular, and the folding ring portion 11133 may have a U-shaped cross-section parallel to the vibration direction D1, so that the first connecting portion 11132 and the second connecting portion 11134 can move relative to each other in the vibration direction D1. Accordingly, the second avoidance hole 11131 may be provided on the second connecting portion 11134, that is, the first connecting portion 11132 is located on the periphery of the second connecting portion 11134. At this time, the first connecting portion 11132 can be connected to the movement cover 1112 , and the second connecting portion 11134 can be connected to the vibration panel 113 or the transducer 112 to seal the assembly gap of the first avoidance hole 11121 .

[0089] In some embodiments of the present application, the sealing film 1113 is a complete film structure. It should be noted that in some other embodiments of the present application, the sealing film 1113 may be provided with at least one micropore, for example, the area of ​​the micropore is less than or equal to 2mm. 2, so that the sealing film 1113 further optimizes the sound leakage reduction while reducing the pressure difference between the inside and outside of the first cavity, that is, the micropores can serve as a pressure relief. Of course, the sealing film 1113 does not need to be provided with micropores. When the movement housing 1111, movement cover 1112, and sealing film 1113 are assembled to form the first cavity, the assembly gaps between the various structural components can serve as a pressure relief.

[0090] Furthermore, the sealing film 1113 may be made of rubber, silicone, or the like.

[0091] Furthermore, the rim portion 11133 protrudes in the vibration direction D1 away from the transducer device 112, that is, the rim portion 11133 extends into the first cavity. This makes it less likely that droplets, dust, etc. that enter the first cavity through the passage will accumulate on the rim portion 11133, compared to when the rim portion 11133 extends into the second cavity. This helps maintain the reliability of the sealing membrane 1113.

[0092] By way of example, referring to Figures 2 and 3, 9, and 10, bracket 1121 may include a first bracket 11211, a second bracket 11212, and a suspension 11213. First bracket 11211 may be connected to the central region of first vibration transmitting plate 115, for example, by forming a one-piece structural component through a metal insert injection molding process. Second bracket 11212 may be connected to the peripheral region of second vibration transmitting plate 1122, and suspension 11213 may be connected to the central region of second vibration transmitting plate 1122, for example, by forming a one-piece structural component through a metal insert injection molding process. Furthermore, one of first bracket 11211 and second bracket 11212 may be provided with a connector pin 11214, and the other may be provided with a socket 11215 for accommodating connector pin 11214. Connector pin 11214 is embedded in socket 11215, thereby connecting first bracket 11211 and second bracket 11212. The number of connector pins 11214 and connector holes 11215 can be multiple, and the two can correspond one to one, such as the four shown in Figure 9. Accordingly, the magnetic circuit system is connected to the suspension 11213, for example, fasteners 1126 connect the suspension 11213, magnet 1125, and the bottom of the magnetic cover 1124 together, or the suspension 11213, magnet 1125, and magnetic cover 1124 are bonded together using adhesive; the coil 1123 can be connected to the second bracket 11212, and the sealing film 1113 can be connected to at least one of the first bracket 11211 and the vibration panel 113.

[0093] In some embodiments, such as shown in FIG9 , the first bracket 11211 may include a main body 11216 and a connector 11217 connected to the main body 11216. The connector 11217 may be columnar and at least partially embedded in the vibration panel 113 to connect the vibration panel 113 to the bracket 1121. Accordingly, the connector column 11214 may be provided on the second bracket 11212, and the connector hole 11215 may be provided on the main body 11216.

[0094] In some embodiments, such as Figure 10, the first bracket 11211 may include a main body 11216 and a connector 11217 connected to the main body 11216. The connector 11217 may be cylindrical, and the vibration panel 113 may be partially embedded in the connector 11217 to connect the vibration panel 113 to the bracket 1121.

[0095] As an example, in conjunction with Figures 2 to 4 , at least one of the vibration panel 113 and the bracket 1121 can be provided with a support end surface corresponding to the area surrounding the second avoidance hole 11131, and the sealing membrane 1113 can be fixed to the aforementioned support end surface, which is simple and reliable. Specifically, for the embodiment shown in Figure 9 , the aforementioned support end surface can be provided at least on the vibration panel 113; and for the embodiment shown in Figure 10 , the aforementioned support end surface can be provided at least on the bracket 1121, for example, the end surface of the connector 11217 that is not connected to the main body 11216 can serve as the support end surface.

[0096] By way of example, in conjunction with Figures 2 to 4 , the bracket 1121 can be provided with a first supporting end surface 11218, for example, the end surface of the connector 11217 not connected to the main body 11216, and the vibration panel 113 can be provided with a second supporting end surface 1131. The first supporting end surface 11218 and the second supporting end surface 1131 can jointly clamp the second connecting portion 11134. In other words, the supporting end surfaces of the vibration panel 113 and the bracket 1121 that face each other jointly clamp the second connecting portion 11134. In this way, when the vibration panel 113 is connected to the bracket 1121, the sealing film 1113 can be further pressed against the bracket 1121, which is simple, reliable, and achieves two goals at one stroke.

[0097] As an example, in conjunction with Figure 4, a recessed area 11125 can be provided on the side of the movement cover plate 1112 facing away from the transducer device 112, a first avoidance hole 11121 is provided at the bottom of the recessed area 11125, and a first connecting portion 11132 can be connected to the bottom of the recessed area 11125 and surround the first avoidance hole 11121. In this way, the recessed area 11125 not only plays a positioning role during the assembly process of the sealing film 1113 and the movement cover plate 1112, but also increases the flatness of the cavity wall surface of the above-mentioned first cavity. Accordingly, the recessed area 11125 can be provided on the inner top 11122.

[0098] Furthermore, the recessed area 11125 may include a first recessed section 11126 and a second recessed section 11127. The first recessed section 11126 is closer to the transducer 112 than the second recessed section 11127 in the vibration direction D1. The second recessed section 11127 has a larger dimension perpendicular to the vibration direction D1 than the first recessed section 11126. In short, the recessed area 11125 is divided into two sections in the vibration direction D1, with the first avoidance hole 11121 disposed at the bottom of the first recessed section 11126. The first connecting portion 11132 is fixed to the bottom of the first recessed section 11126.

[0099] In some embodiments, the first connecting portion 11132 can be connected to the bottom of the first recessed section 11126 via double-sided tape, and the second recessed section 11127 can contain glue, which helps to increase the reliability of the connection between the sealing film 1113 and the movement cover plate 1112. In other words, the sidewall of the second recessed section 11127 cooperates with the first connecting portion 11132 to form an annular glue groove, which helps to prevent glue overflow.

[0100] In some embodiments, the first connection portion 11132 can be connected to the bottom of the first recessed section 11126 by glue. Alternatively, in some embodiments, the first connection portion 11132 can be connected to the second recessed section 11127 by glue.

[0101] Based on the above description, the first connecting portion 11132 can be fixed to the bottom of the first recessed section 11126 via the first colloid 11135, so that the sealing film 1113 is connected to the movement cover 1112; the second connecting portion 11134 can be fixed to the end surface of the connecting portion 11217 that is not connected to the main body 11216 (i.e., the first supporting end surface 11218) via the second colloid 11136, so that the sealing film 1113 is connected to the bracket 1121. Among them, the vibration panel 113 can further press the sealing film 1113 on the bracket 1121. Furthermore, the first colloid 11135 and the second colloid 11136 can be double-sided tape or glue respectively. It is worth noting that when the first colloid 11135 and the second colloid 11136 are double-sided tapes, they can be pre-fixed to the sealing film 1113; and when the first colloid 11135 and the second colloid 11136 are glues, they can be pre-fixed to the movement cover 1112 and the bracket 1121. Furthermore, without considering factors such as processing errors and assembly errors, the first support end surface 11218 and the bottom of the first recessed section 11126 can be flush in the vibration direction D1.

[0102] By way of example, in conjunction with Figures 2 and 3 , 7 and 8 , movement housing 1111 may include a first cylindrical sidewall 11113 and a first annular pedestal 11114 connected to the inner wall of first cylindrical sidewall 11113. Outer bottom 11124 may be supported on first annular pedestal 11114, and reinforcing member 1143 may be located between the inner wall of first cylindrical sidewall 11113 and the outer wall of connecting portion 11123. Accordingly, one of snap-fit ​​protrusion 11111 and snap-fit ​​groove 11434 may be provided on first cylindrical sidewall 11113, while the other may be provided on reinforcing member 1143. For ease of description, the snap-on protrusion 11111 or snap-on groove 11434 provided on the first cylindrical sidewall 11113 can be further defined as a snap-on portion. That is, the snap-on portion can be provided on the inner wall surface of the first cylindrical sidewall 11113, so that the face-mounting assembly 114 engages with the snap-on portion via the flange 11432. Similarly, the connecting hole 11112 can also be provided on the first cylindrical sidewall 11113. Furthermore, the movement cover 1112 can press the edge area of ​​the first vibration transmission plate 115 against the first annular support 11114.

[0103] Furthermore, a plurality of columns 11115, such as the six shown in FIG8 , may be provided on the first annular support 11114. The movement cover 1112 may be supported on the first annular support 11114 and may be plugged in and matched with the columns 11115. The columns 11115 may at least play a positioning role during the assembly process of the movement cover 1112 and the movement housing 1111. Accordingly, the outer bottom 11124 may be supported on the first annular support 11114 and may be plugged in and matched with the columns 11115. Among them, the plurality of columns 11115, the plurality of snap portions (such as the snap protrusions 11111, which will not be described in detail below) and the plurality of connecting holes 11112 may be respectively spaced apart in the circumferential direction of the first cylindrical side wall 11113. The plurality of snap portions and the plurality of connecting holes 11112 may be staggered from each other in the circumferential direction of the first cylindrical side wall 11113 so that the three are reasonably distributed. Furthermore, at least two of the plurality of columns 11115 and at least two of the plurality of connecting holes 11112 may at least partially overlap in a one-to-one correspondence in the circumferential direction of the first cylindrical side wall 11113 , so that the column 11115 is located between two adjacent snap-fit ​​portions.

[0104] As an example, the pillars 11115 can be heat-seal pillars to further secure the movement cover plate 1112 to the first annular support 11114. The pillars 11115 shown in Figures 2 and 3, 7, and 8 are in their pre-seal form. After heat-seal, they generally do not extend beyond the corresponding connecting holes 11112 to avoid interfering with the flow of air into and out of the first cavity.

[0105] As an example, in conjunction with Figures 7 and 8, the shell assembly 111 has a long axis (for example, the direction indicated by the arrow D3 in Figure 8) and a short axis (for example, the direction indicated by the arrow D4 in Figure 8) that are perpendicular to the vibration direction D1 and orthogonal to each other. The size of the first annular support 11114 on the long axis D3 can be greater than the size of the first annular support 11114 on the short axis D4. For example, the first annular support 11114 is arranged in a runway shape. Among them, multiple columns 11115 can be symmetrically arranged on both sides of the long axis D3 and the short axis D4 to increase the reliability of the connection between the movement cover plate 1112 and the movement shell 1111; similarly, multiple snap-fit ​​parts can be symmetrically arranged on both sides of the long axis D3 and the short axis D4 to increase the reliability of the face-mounted assembly 114 and the movement shell 1111.

[0106] As an example, referring to Figures 7 and 8 , the plurality of uprights 11115 and the plurality of snap portions can be staggered to avoid mold release interference during molding processes such as injection molding. Accordingly, a connecting hole 11112 can be provided between any two adjacent snap portions along the circumference of the first cylindrical sidewall 11113, such that the size of the connecting hole 11112 along the circumference of the first cylindrical sidewall 11113 is as large as possible.

[0107] As an example, in conjunction with Figures 7 and 8 , when viewed along the vibration direction D1, the connecting holes 11112 can be divided into four groups. Two groups of connecting holes 11112 can be arranged relative to each other on the major axis D3, and the remaining two groups of connecting holes 11112 can be arranged relative to each other on the minor axis D4. This helps reduce standing waves in the first cavity. Although each group of connecting holes 11112 in Figures 7 and 8 has only one connecting hole 11112, those skilled in the art can set multiple connecting holes 11112 in at least one group of connecting holes 11112 according to actual needs, which will not be repeated here.

[0108] As an example, in conjunction with Figures 2, 3 and 11, the movement module 11 may include a microphone assembly 116, which is disposed in the housing assembly 111. The microphone assembly 116 can pick up at least one of ambient sound, user voice, and other sounds. Furthermore, the microphone assembly 116 may include a first microphone 1161, which falls on the transducer device 112 when projected onto the transducer device 112 along the vibration direction D1. For example, the first microphone 1161 is fixed to the bottom of the housing assembly 111 and is spaced apart from the transducer device 112 in the vibration direction D1. Among them, the movement module 11 can further include a limit member 117 arranged in the shell assembly 111, and the limit member 117 is used to stop the transducer device 112 when the movement amplitude of the transducer device 112 along the vibration direction D1 exceeds a preset amplitude threshold, so that a predetermined distance is maintained between the transducer device 112 and the first microphone 1161. This is conducive to preventing the first microphone 1161 from being damaged by the transducer device 112, especially under extreme working conditions such as falling or collision of the movement module 11.

[0109] Furthermore, the amplitude threshold can be greater than the maximum amplitude of the transducer 112 when the core module 11 is operating normally. In other words, when the user uses the electronic device 10 daily, even if the volume of the electronic device 10 is turned up to the maximum, the transducer 112 will not collide with the limiter 117 and other structures, thereby preventing the core module 11 from generating noise.

[0110] In some embodiments, the limiter 117 can be arranged in a ring shape or a block shape. The center of the limiter 117 and the center of the transducer 112 can be aligned in the vibration direction D1, so that the distribution of the force when the limiter 117 stops the transducer 112 is more uniform. In some embodiments of the present application, the limiter 117 can be arranged adjacent to the first microphone 1161, so as to better prevent the first microphone 1161 from being damaged by the transducer 112 through the limiter 117, especially under extreme working conditions such as the movement module 11 falling or colliding. The limiter 117 and the first microphone 1161 are arranged adjacent to each other, which means that in the direction of the line connecting the center of the limiter 117 and the center of the first microphone 1161, the distance between the limiter 117 and the first microphone 1161 can be at least less than half of the size of the transducer 112 in the direction of the line. For example, the position limiter 117 being positioned adjacent to the first microphone 1161 means that, in the direction of the line connecting the center of the position limiter 117 and the center of the first microphone 1161, the distance between the position limiter 117 and the first microphone 1161 can be at least 1 / 2, 1 / 3, 1 / 4, 1 / 5, etc., of the dimension of the transducer 112 in that direction. In some embodiments, the position limiter 117 can be made of polycarbonate or a material blended with at least one of glass fiber and carbon fiber. Alternatively, the position limiter 117 can be made of a material with a certain degree of elasticity, such as silicone, rubber, or sponge. When the transducer 112 collides with the position limiter 117, the position limiter 117 can provide a certain degree of cushioning, thereby preventing or mitigating potential damage to the transducer 112. It is understood that, in the present application, the position limiter 117 can also be made of any other material and is not specifically limited thereto. The position limiter 117 can be fixed to the bottom of the housing assembly 111 or to the transducer 112. Furthermore, when the limiting member 117 is fixed to the bottom of the housing assembly 111 , the limiting member 117 and the housing assembly 111 may be an integrally formed structural component.

[0111] By way of example, in conjunction with FIG2 , the stopper 117 and the first microphone 1161 can be arranged to remain relatively fixed. For example, both can be fixed to the bottom of the movement housing 1111. In another example, the stopper 117 can be a part of the movement housing 1111, while the first microphone 1161 can be fixed to the bottom of the movement housing 1111. The orthographic projection of the transducer 112 along the vibration direction D1 covers the first microphone 1161 and the stopper 117, so that the stopper 117 stops the transducer 112. Furthermore, in the vibration direction D1, the side of the stopper 117 facing the transducer 112 is higher than the side of the first microphone 1161 facing the transducer 112, thereby preventing the first microphone 1161 from being damaged by the transducer 112.

[0112] In some other embodiments, the stopper 117 and the first microphone 1161 may both be fixed to the bottom of the housing assembly 111, with the stopper 117 fixed to the transducer device 112, and the first microphone 1161 fixed to the bottom of the housing assembly 111. In the vibration direction D1, the distance between the side of the stopper 117 facing the bottom of the housing assembly 111 and the bottom of the housing assembly 111 is smaller than the distance between the side of the first microphone 1161 facing the transducer device 112 and the transducer device 112, thereby preventing the first microphone 1161 from being damaged by the transducer device 112.

[0113] As an example, referring to Figures 2 and 3 , the microphone assembly 116 may include a second microphone 1162 and a flexible circuit board 1163 connecting the first and second microphones 1161 and 1162. The second microphone 1162 is fixed to the side wall of the core housing 1111. The core housing 1111 may be provided with a wiring groove, within which the flexible circuit board 1163 is secured. This groove serves to position the flexible circuit board 1163 during assembly with the core housing 1111 and prevents glue from overflowing when the two are glued together. Since the flexible circuit board 1163 is secured within the groove, the area where the flexible circuit board 1163 resides can be considered the wiring groove. Furthermore, the stopper 117 and the wiring groove are offset to prevent interference during processing. Accordingly, the core housing 1111 may be provided with sound pickup holes for the first and second microphones 1161 and 1162, respectively.

[0114] As an example, in combination with Figure 11, the flexible circuit board 1163 may include a first flexible circuit portion 11631 and a second flexible circuit portion 11632 that are integrally connected. The first microphone 1161 can be attached to the end of the first flexible circuit portion 11631 away from the second flexible circuit portion 11632 by means of surface mount technology (SMT), and the second microphone 1162 can also be attached to the end of the second flexible circuit portion 11632 away from the first flexible circuit portion 11631 by means of surface mount technology, thereby forming a microphone assembly 116 for easy assembly. Among them, the angle between the orthographic projection of the first flexible circuit part 11631 on a reference plane (such as paper) perpendicular to the vibration direction D1 and the orthographic projection of the second flexible circuit part 11632 on the aforementioned reference plane can be greater than 90° and less than 180°, that is, the flexible circuit board 1163 is bent into an obtuse angle, so that the first microphone 1161 and the second microphone 1162 are diagonally arranged in the shell assembly 111, thereby increasing the distance between the two microphones and improving the sound pickup effect of the microphone assembly 116.

[0115] As an example, in conjunction with Figures 2 and 3, the movement housing 1111 may include a second cylindrical sidewall 11116 and a bottom wall 11117 connected to one end of the second cylindrical sidewall 11116. The open end of the second cylindrical sidewall 11116 may be provided with a second annular support 11118. The second cylindrical sidewall 11116 partially extends into the first cylindrical sidewall 11113, so that the first cylindrical sidewall 11113 is supported on the second annular support 11118. The overlapping portion of the first cylindrical sidewall 11113 and the second cylindrical sidewall 11116 may be provided with a snap-fit ​​structure to enable the two to be snap-fitted and fixed. The second annular support 11118 may be provided with a glue groove to enable the first cylindrical sidewall 11113 to be glued and fixed to the second annular support 11118, which helps to increase the reliability of the connection between the first cylindrical sidewall 11113 and the second cylindrical sidewall 11116. Correspondingly, the first microphone 1161 can be fixed on the bottom wall 11117, the second microphone 1162 can be fixed on the second cylindrical side wall 11116, and the above-mentioned wiring groove can be partially opened on the bottom wall 11117 and the other part opened on the second cylindrical side wall 11116; the limiting member 117 can be fixed on the bottom wall 11117 or serve as a part of the structure of the bottom wall 11117.

[0116] Based on the above description, the movement housing 1111 may include a first housing and a second housing connected to the first housing. The first housing may include a first cylindrical sidewall 11113 and a first annular support 11114 connected to the inner wall of the first cylindrical sidewall 11113. The second housing may include a second cylindrical sidewall 11116 and a bottom wall 11117 connected to one end of the second cylindrical sidewall 11116. The second cylindrical sidewall 11116 is connected to the first cylindrical sidewall 11113 so that the second housing seals one end of the first cylindrical sidewall 11113, while the other end of the first cylindrical sidewall 11113 is open. Accordingly, the microphone assembly 116 may be fixed within the second housing, and the depth of the second housing is relatively shallow, which helps to reduce the difficulty of assembling the microphone assembly 116. Furthermore, the housing assembly 111 may include a flexible covering 1114 covering the outside of the second housing. For example, the flexible covering 1114 covers the outside of the second cylindrical sidewall 11116 and the bottom wall 11117. The outer surface of the flexible covering 1114 may be flush with the outer surface of the first cylindrical sidewall 11113 to fill the step between the first cylindrical sidewall 11113 and the second cylindrical sidewall 11116. The hardness of the flexible covering 1114 may be less than that of the movement housing 1111.

[0117] By way of example, with reference to Figures 12, 15, and 21, the electronic device 10 may include a housing assembly 121, a circuit board 1221, and an antenna bracket 123 disposed within the housing assembly 121. The antenna bracket 123 may be supported on one side of the circuit board 1221. The housing assembly 121 may include a housing 1211 and a lampshade 1222 disposed within a sidewall of the housing 1211. The antenna bracket 123 and the circuit board 1221 are at least partially housed within the housing 1211. The antenna bracket 123 may be located on a side of the circuit board 1221 facing the lampshade 1222. Furthermore, an indicator light 1223 may be provided on the side of the circuit board 1221 facing the lampshade 1222. The antenna bracket 123 may include an antenna support portion 1231 and a light guide portion 1232 connected to the antenna support portion 1231. Both the light guide portion 1232 and the lampshade 1222 are light-transmitting members. The light guide portion 1232 is configured to guide light emitted by the indicator light 1223 to the exterior of the electronic device 10. For example, light emitted by the indicator light 1223 is transmitted through the light guide portion 1232 to the lampshade 1222 and then emitted to the exterior of the electronic device 10. In this manner, even though the distance between the indicator light 1223 and the lampshade 1222 is relatively large due to the presence of the antenna bracket 123, the guidance of the light guide portion 1232 helps reduce the loss of light emitted by the indicator light 1223, eliminating the need to increase the luminous power of the indicator light 1223, thereby reducing the power consumption of the indicator light 1223 and extending the service life of the indicator light 1223.

[0118] In some embodiments, the outer surface of the light guide 1232 can be coated with a reflective coating or have a textured surface. This allows the light to refract within the light guide 1232, reducing light leakage from the sides of the light guide 1232 and improving light utilization. The light-entering surface of the light guide 1232 facing the indicator light 1223 and the light-emitting surface facing the lampshade 1222 need to be exposed, for example, without a reflective coating or textured surface, to allow the light to pass through the light guide 1232.

[0119] By way of example, in conjunction with Figures 12, 15, and 21, the center of the orthographic projection of the lampshade 1222 on the circuit board 1221 may not coincide with the center of the indicator light 1223. That is, the lampshade 1222 is offset relative to the indicator light 1223, thereby making the arrangement of the lampshade 1222 more flexible. Specifically, in the normal direction of the circuit board 1221 (e.g., the direction indicated by arrow D5 in Figures 12 and 15), the cross-sectional area of ​​the end of the light guide 1232 near the circuit board 1221 may be larger than the cross-sectional area of ​​the other end of the light guide 1232 near the lampshade 1222, thereby changing the optical path of the light emitted by the indicator light 1223 and converging the light emitted by the indicator light 1223 and reaching the lampshade 1222. Of course, the center of the orthographic projection of the lampshade 1222 on the circuit board 1221 may also coincide with the center of the indicator light 1223.

[0120] As an example, in combination with Figure 12, the end surface of the light guide portion 1232 facing the indicator light 1223 can be set to a curved surface that is recessed into the interior of the light guide portion 1232, similar to a concave structure, to better collect the light emitted by the indicator light 1223.

[0121] By way of example, in conjunction with Figures 12 and 21 , the antenna support 123 may include a connecting rib 1233 connecting the light guide portion 1232 and the antenna support portion 1231. Specifically, the light guide portion 1232 is connected to the antenna support portion 1231 via the connecting rib 1233. Furthermore, the ratio between the thickness of the connecting rib 1233 in the normal direction D5 and the height of the light guide portion 1232 in the normal direction D5 may be between 0.3 and 0.5. If this ratio is too small, the connection strength between the light guide portion 1232 and the antenna support portion 1231 may be insufficient. If this ratio is too large, excessive light from the indicator light 1223 may leak through the connecting rib 1233 into the antenna support portion 1231.

[0122] In some embodiments, the antenna support portion 1231 , the light guide portion 1232 , and the connecting rib 1233 may be an integrally formed structural component made of the same material, for example, integrally formed by an injection molding process.

[0123] In some embodiments, the antenna support portion 1231 and the light guide portion 1232 may be integrally formed from different materials, for example, by a two-color injection molding process, wherein the connecting rib 1233 may serve as a portion of the antenna support portion 1231 or the light guide portion 1232 .

[0124] As an example, referring to Figures 12, 17, and 21, an antenna pattern 1224 may be provided on the side of the antenna support portion 1231 facing away from the circuit board 1221. The antenna pattern 1224 may be abutted against the circuit board 1221 via a metal elastic member 1225 to achieve electrical contact. The antenna pattern 1224 may be located on the side of the antenna support portion 1231 facing the lampshade 1222 to increase the distance between the antenna pattern 1224 and the circuit board 1221, thereby increasing the antenna clearance area and enhancing the anti-interference capability of the antenna pattern 1224. Furthermore, the antenna pattern 1224 may be formed on the antenna support portion 1231 using laser direct structuring (LDS) technology, or may be a flexible printed circuit board adhered to the antenna support portion 1231. The metal elastic member 1225 may be a pogo pin or a metal dome, etc., without limitation. Furthermore, the metal elastic member 1225 may be fixed to the circuit board 1221.

[0125] It should be noted that: in conjunction with Figures 1 and 12, in the worn state, the lampshade 1222 can be closer to the outside than the circuit board 1221, so that the light emitted by the indicator light 1223 and guided by the light guide 1232 and the lampshade 1222 will not be blocked. Similarly, in the worn state, the antenna pattern 1224 can be closer to the outside than the circuit board 1221, for example, the antenna pattern 1224 is located between the circuit board 1221 and the lampshade 1222, so as to further increase the anti-interference ability of the antenna pattern 1224. Furthermore, in some other embodiments, the electronic device 10 may also not include the antenna bracket 123, for example, the antenna pattern 1224 is provided on the housing assembly 121 or on the circuit board 1221, and for another example, the lampshade 1222 further extends into the housing assembly 121 to shorten the distance between it and the indicator light 1223.

[0126] As an example, referring to FIG21 , the antenna bracket 123 may include a positioning post 1234 and a latching portion 1235 connected to the antenna support portion 1231. The positioning post 1234 serves to position the antenna bracket 123 during assembly with the circuit board 1221, while the latching portion 1235 secures the antenna bracket 123 to the circuit board 1221. The number of positioning posts 1234 and latching portions 1235 may be multiple. After the positioning posts 1234 are inserted into the positioning holes on the circuit board 1221, the latching portions 1235 can latch onto different sides of the circuit board 1221, ensuring a more secure connection between the antenna bracket 123 and the circuit board 1221. It should be noted that due to the perspective, FIG21 only illustrates one positioning post 1234 and one latching portion 1235. Accordingly, when the antenna bracket 123 is secured to the circuit board 1221, the metal elastic member 1225 simultaneously makes electrical contact with the antenna pattern 1224.

[0127] By way of example, with reference to Figures 12, 15, and 17, the housing assembly 121 may include an end cap 12121 connected to the housing 1211. The antenna bracket 123 and the circuit board 1221 may be inserted together into the housing 1211 along an insertion direction (e.g., the direction indicated by arrow D6 in Figures 15 and 17) through the open end of the housing 1211, at least partially. The end cap 12121 is further connected to the open end of the housing 1211, so that the circuit board 1221, the antenna bracket 123, and their associated components are positioned within the housing assembly 121. Thus, since the lampshade 1222 and the antenna bracket 123 are two separate components, they and their associated components can be assembled together according to a specific assembly sequence, eliminating the technical issues of structural interference that could hinder assembly of the electronic device 10. Accordingly, after the antenna bracket 123 and the circuit board 1221 are assembled, the light guide 1232 is positioned between the indicator light 1223 and the lampshade 1222.

[0128] Similarly, the end cap 12121 can partially extend into the silo body 1211 and can be supported on the third annular support on the inner side of the open end of the silo body 1211. The overlapping portion of the end cap 12121 and the silo body 1211 can be provided with a snap-fit ​​structure to allow the two to be snap-fitted and fixed; the aforementioned third annular support can be provided with a glue groove to allow the end cap 12121 to be glued and fixed to the aforementioned third annular support, which is conducive to increasing the reliability of the connection between the end cap 12121 and the silo body 1211. Furthermore, the shell assembly 121 can include a flexible coating 12122 covering the outside of the end cap 12121. The outer surface of the flexible coating 12122 can be flush with the outer surface of the silo body 1211 to fill the step difference between the end cap 12121 and the silo body 1211. The hardness of the flexible coating 12122 can be less than the hardness of the end cap 12121. It is worth noting that the flexible covering layer 12122 and the flexible covering layer 1114 can be an integral structural part formed by injection molding.

[0129] As an example, in conjunction with Figures 12 and 18, a stepped hole 1213 may be provided on the side wall of the housing 1211, and the lampshade 1222 may be assembled in the stepped hole 1213. The lampshade 1222 may include a first light-transmitting portion 12221 and a second light-transmitting portion 12222 that are integrally connected, wherein the radial dimension of the first light-transmitting portion 12221 is smaller than the radial dimension of the second light-transmitting portion 12222; the stepped hole 1213 may include a first hole segment and a second hole segment that are connected to each other, wherein the radial dimension of the first hole segment is smaller than the radial dimension of the second hole segment, and the first hole segment is closer to the circuit board than the second hole segment in the normal direction D5; the first light-transmitting portion 12221 is embedded in the first hole segment, and the second light-transmitting portion 12222 is embedded in the second hole segment, and is supported on the stepped surface of the stepped hole 1213. In other words, the lampshade 1222 can be assembled in the stepped hole 1213 along the assembly direction from outside to inside, which helps to prevent the lampshade 1222 from intruding into the chamber body 1211 under the action of external force, so as to maintain the relative position relationship between the lampshade 1222 and the chamber body 1211.

[0130] As an example, in conjunction with Figures 12, 18, and 21, the electronic device 10 may include a sliding key assembly 124 connected to the housing assembly 121. The sliding key assembly 124 can slide along a sliding direction (e.g., the direction indicated by arrow D7 in Figure 12) under the action of an external force to toggle a toggle switch 1226 disposed on the circuit board 1221 to expand the control functions of the electronic device 10, such as for powering on / off the electronic device 10. The sliding key assembly 124 can extend from the outside of the housing assembly 121 into the inside of the housing assembly 121 via a slide groove 1214 on the housing assembly 121, and further connect to the toggle switch 1226 via a relief groove 1236 on the antenna bracket 123, so that a user can toggle the toggle switch 1226 via the sliding key assembly 124. Furthermore, part of the sliding key assembly 124 can be limited between the antenna bracket 123 and the shell assembly 121, which can prevent the sliding key assembly 124 from intruding into the shell assembly 121 under the action of external force, and can also prevent the sliding key assembly 124 from separating from the shell assembly 121.

[0131] By way of example, referring to Figures 12 and 18 to 21 , the sliding key assembly 124 may include an adapter frame 1241 and a sliding key 1242. The sliding key 1242 may be connected to the toggle switch 1226 via the adapter frame 1241 and is configured to receive external force applied by a user to toggle the toggle switch 1226. The adapter frame 1241 is disposed within the housing assembly 121 and extends from one side of the antenna bracket 123 to the other side via the avoidance groove 1236, thereby connecting to the toggle switch 1226. The sliding key 1242 extends from the outside of the housing assembly 121 into the inside of the housing assembly 121 via the slide groove 1214, thereby connecting to the adapter frame 1241. In short, the sliding key 1242 and the adapter frame 1241 can be assembled and connected. As such, since adapter frame 1241 and slide key 1242 are two separate structural components, they and their associated structural components can be assembled together according to a specific assembly sequence, eliminating the technical issues of structural interference that would hinder assembly of electronic device 10. Accordingly, a portion of adapter frame 1241 can be positioned between antenna bracket 123 and housing assembly 121 to prevent slide key assembly 124 from separating from housing assembly 121 after the slide key assembly 124 and other structural components have been assembled. Of course, in some other embodiments, in order to prevent the sliding key assembly 124 from separating from the shell assembly 121, for example, a portion of the sliding key 1242 is limited to the inner side of the shell assembly 121 facing the circuit board 1221, and for example, an additional limiting member such as a retaining ring or a pin independent of the sliding key 1242 is provided. After the aforementioned limiting member is assembled with the sliding key 1242, it is limited to the inner side of the shell assembly 121 facing the circuit board 1221; in order for the sliding key assembly 124 to toggle the toggle switch 1226, the sliding key assembly 124 may also not include the adapter frame 1241, for example, the second connector 12422 mentioned later is connected to the toggle switch 1226.

[0132] As an example, in conjunction with Figures 12, 18 to 21, the adapter frame 1241 may include an annular main body portion 12411 and a first plug portion 12412 connected to the annular main body portion 12411, the annular main body portion 12411 is located on the side of the antenna bracket 123 away from the circuit board 1221, the first plug portion 12412 passes through the avoidance groove 1236 and is connected to the toggle switch 1226; the sliding key 1242 may include an operating portion 12421, a second plug portion 12422 connected to the operating portion 12421 and a plug portion 12423 connected to the second plug portion 12424. 422, the locking portion 12423 is connected to the operating portion 12421, and the operating portion 12421 is located on the outside of the shell assembly 121 to receive the external force applied by the user. The second connecting portion 12422 passes through the slide groove 1214 and extends into the slot 12413 of the annular main body 12411. The locking portion 12423 is locked with the side of the annular main body 12411 facing the circuit board 1221, that is, the locking portion 12423 is located on the side of the annular main body 12411 facing the circuit board 1221, so that the sliding key 1242 is locked and fixed with the adapter frame 1241. Of course, in some other embodiments, in order to achieve the snap-fit ​​fixation of the sliding key 1242 and the adapter frame 1241, the sliding key 1242 may also not include the snap-fit ​​portion 12423. For example, an additional limiting member such as a retaining ring or a pin independent of the sliding key 1242 is provided. After the aforementioned limiting member is assembled with the sliding key 1242, it is located on the side of the adapter frame 1241 facing the circuit board 1221.

[0133] In some embodiments, the length of the annular main body 12411 in the sliding direction D7 may be greater than the length of the avoidance groove 1236 in the sliding direction D7, so that the annular main body 12411 can be limited between the antenna bracket 123 and the shell assembly 121.

[0134] In some embodiments, the width of the annular main body 12411 in a direction perpendicular to the sliding direction D7 and the plugging direction can be greater than the width of the avoidance groove 1236 in a direction perpendicular to the sliding direction D7 and the aforementioned plugging direction, so that the annular main body 12411 can be constrained between the antenna bracket 123 and the housing assembly 121. The aforementioned plugging direction can be defined as the assembly direction of the plug-in connection between the sliding key 1242 and the adapter bracket 1241. For example, the plugging direction is parallel to the extension direction of the second plugging portion 12422.

[0135] Because the length of annular main body 12411 can be greater than the length of avoidance groove 1236, and the width of annular main body 12411 can be greater than the width of avoidance groove 1236, annular main body 12411 can be supported on antenna bracket 123, particularly during the process of connecting sliding key 1242 to adapter bracket 1241 along the aforementioned assembly direction, thereby simplifying the assembly process. Specifically, referring to Figures 12 and 21, a limiting groove 1237 can be provided on the side of antenna bracket 123 facing away from circuit board 1221. Avoidance groove 1236 is provided at the bottom of limiting groove 1237, and annular main body 12411 can be at least partially located within limiting groove 1237. This helps reduce the size of housing assembly 121 in normal direction D5.

[0136] As an example, in conjunction with Figures 12, 19, and 20, the second plug-in portion 12422 and the engaging portion 12423 can be arranged in two groups spaced apart along the sliding direction D7, and the two engaging portions 12423 can be at least partially located on opposite sides of the two second plug-in portions 12422, respectively, to facilitate the locking and fixing of the sliding key 1242 and the adapter frame 1241, and to help prevent relative movement between the sliding key 1242 and the adapter frame 1241. Accordingly, the size of the slot 12413 in the sliding direction D7 can be larger than the size of the slot 12413 in a direction perpendicular to the sliding direction D7 and the aforementioned plug-in direction. The side of the slot 12413 facing away from the circuit board 1221 can be provided with a first guide surface 12414, and the engaging portion 12423 can be provided with a second guide surface 12424. In this way, in the process of the sliding key 1242 extending into the adapter frame 1241, the second guide surface 12424 and the first guide surface 12414 cooperate with each other to make the two groups of second connecting parts 12422 and the locking part 12423 approach each other, so that the two locking parts 12423 pass through the slot 12413; accordingly, after the two locking parts 12423 pass through the slot 12413, the relative position between the two groups of second connecting parts 12422 and the locking part 12423 can be restored to the state before the sliding key 1242 and the adapter frame 1241 are assembled, so that the two locking parts 12423 are stopped by the annular main body 12411 in the opposite direction of the sliding key 1242 extending into the adapter frame 1241, thereby realizing the locking and fixation of the sliding key 1242 and the adapter frame 1241. Of course, in some embodiments, the second connecting portion 12422 and the locking portion 12423 may be provided in only one group, and the relative fixation between the sliding key 1242 and the adapter frame 1241 may be maintained by a snap ring.

[0137] As an example, in conjunction with Figures 12 and 17 , the extension direction of the switch handle of the toggle switch 1226 can be perpendicular to the normal direction D5, which helps reduce the size of the housing assembly 121 in the normal direction D5. Accordingly, in conjunction with Figure 20 , the number of first connecting portions 12412 can be two, and the two first connecting portions 12412 are spaced apart in the sliding direction D7. The switch handle of the toggle switch 1226 is inserted between the two first connecting portions 12412, so that the adapter frame 1241 and the switch handle of the toggle switch 1226 are fixedly engaged, thereby facilitating the sliding key 1242 to toggle the toggle switch 1226 through the adapter frame 1241. Of course, in some embodiments, the number of the first connector 12412 can also be one, and a hole can be provided on the switch handle of the toggle switch 1226 to allow the first connector 12412 to partially extend into the aforementioned hole, and the first connector 12412 can also be connected to the switch handle of the toggle switch 1226.

[0138] As an example, in conjunction with Figures 12 and 13, a sealing groove 12425 surrounding the slide groove 1214 can be provided on the inner side of the operating portion 12421 facing the circuit board 1221, and the sliding key assembly 124 can include a sealing ring 1243 disposed in the sealing groove 12425 to seal the slide groove 1214. In addition, since the sealing ring 1243 has a certain amount of compression, the sealing ring 1243 can also provide a certain amount of damping when the user operates the sliding key 1242, resulting in a better sliding feel. Among them, the sealing ring 1243 shown in Figures 12 and 13 is its form before compression. After compression, it has a certain amount of deformation to elastically support between the sliding key 1242 and the housing assembly 121 and achieve a good sealing effect on the slide groove 1214. Of course, in some other embodiments, the sealing groove 12425 can also be provided on the housing assembly 121.

[0139] Because the sealing ring 1243 is elastically supported between the operating portion 12421 and the housing assembly 121, the adapter frame 1241 can be pressed against the housing assembly 121 to prevent the sliding key assembly 124 from shaking relative to the housing assembly 121. Referring to FIG20 , the adapter frame 1241 may include sliding ribs 12415 disposed on the side of the annular main body 12411 facing away from the circuit board 1221. The adapter frame 1241 is slidably supported on the housing assembly 121 via the sliding ribs 12415 to reduce the contact area between the adapter frame 1241 and the housing assembly 121, thereby reducing frictional resistance when the sliding key assembly 124 slides relative to the housing assembly 121.

[0140] In some embodiments, the number of sliding ribs 12415 can be multiple, such as two as shown in Figure 20. The multiple sliding ribs 12415 can be strip-shaped and located on both sides of the slot 12413 in a direction perpendicular to the sliding direction D7 and the above-mentioned plug-in direction. Each sliding rib 12415 can extend along the sliding direction D7.

[0141] In some embodiments, the sliding rib 12415 can be arranged in a ring shape and surround the slot 12413.

[0142] As an example, in combination with Figures 12, 13 and 18, a recessed area 1215 can be provided on the outer side of the shell assembly 121, the slide groove 1214 is provided at the bottom of the recessed area 1215, and the operating part 12421 can be at least partially located in the recessed area 1215, which is conducive to reducing the size of the electronic device 10 in the normal direction D5.

[0143] In some embodiments, after the sliding key assembly 124 slides relative to the shell assembly 121 along the sliding direction D7 until the toggle switch 1226 is in the open state or the closed state, the operating portion 12421 can be stopped by the side wall of the recessed area 1215 to prevent the sliding key assembly 124 from being over-dialed.

[0144] In some embodiments, after the sliding key assembly 124 slides relative to the shell assembly 121 along the sliding direction D7 until the toggle switch 1226 is in the open state or the closed state, the annular body 12411 can be stopped by the side wall of the limiting groove 1237 to prevent the sliding key assembly 124 from being over-dialed.

[0145] As an example, in conjunction with Figures 12 and 13, the bottom of the recessed area 1215 is provided with an annular groove 1216 at the position where it is connected to the side wall of the recessed area 1215 to eliminate the R angle at the corner between the bottom of the recessed area 1215 and the side wall, especially when the shell assembly 121 is made by an injection molding process. Among them, the electronic device 10 may include a gasket 1244 attached to the bottom of the recessed area 1215, the gasket 1244 covers the annular groove 1216, and the edge of the gasket 1244 is suspended above the annular groove 1216 to allow the gasket 1244 to be attached flatly and avoid the edge of the gasket 1244 from warping. Accordingly, the sliding key assembly 124 can be supported on the gasket 1244. In addition, since the edge of the gasket 1244 will not warp, the sliding key assembly 124 can slide into place along the sliding direction D7. For example, after the sliding key assembly 124 slides relative to the housing assembly 121 along the sliding direction D7 until the toggle switch 1226 is in the on state or the off state, the edge of the operating portion 12421 is located above the annular groove 1216 .

[0146] Furthermore, the outer side wall of the annular groove 1216 away from the sliding groove 1214 can be flush with the side wall of the recessed area 1215 .

[0147] In some embodiments, the gasket 1244 may be provided with information such as text, color, or symbols to indicate the on or off state of the toggle switch 1226. For example, the text "ON" and "OFF" may indicate the on or off state, respectively, or the colors green and red may indicate the on or off state, respectively. The information may be provided on the inner side of the gasket 1244, facing the bottom of the recessed area 1215, to prevent it from being worn away. Alternatively, the information may be provided on the bottom of the recessed area 1215.

[0148] In some embodiments, the gasket 1244 can be used to adjust the damping generated by the sealing ring 1243 during the sliding key assembly 124 sliding relative to the housing assembly 121 along the sliding direction D7.

[0149] As an example, in combination with Figures 12 and 18, the stepped hole 1213, the slide groove 1214 and the recessed area 1215 can be located on the same side wall of the housing 1211, so that the sliding key assembly 124 and the lampshade 1222 are located on the same side of the circuit board 1221, so that the user can operate the sliding key assembly 124 when wearing it.

[0150] As an example, in conjunction with Figures 12 and 14, the electronic device 10 includes a third microphone 1251 disposed within the housing assembly 121. The third microphone 1251 can pick up at least one of ambient sound, user voice, and other sounds. The housing assembly 121 can be provided with a sound pickup channel 1217, and the third microphone 1251 is configured to pick up sound transmitted through the sound pickup channel 1217. Furthermore, the sound pickup channel 1217 can include a first channel section 12171 and a second channel section 12172 that are interconnected. In some embodiments of the present application, the first channel section 12171 and the second channel section 12172 are interconnected, connecting the interior of the housing assembly 121 with the outside world. The first channel section 12171 is closer to the third microphone 1251 than the second channel section 12172, and the first central axis of the first channel section 12171 and the second central axis of the second channel section 12172 may not coincide. In this way, the first channel section 12171 and the second channel section 12172 are offset from each other, which helps to prevent external liquid droplets from directly impacting the third microphone 1251, thereby extending the service life of the third microphone 1251.

[0151] In some other embodiments of the present application, the sound pickup channel 1217 may include three or more channel segments, which are interconnected and connect the interior of the shell assembly 121 with the outside.

[0152] Furthermore, the electronic device 10 may include a protective net 1252 disposed within the housing assembly 121, with the protective net 1252 covering the first channel section 12171. This further helps prevent external liquid droplets from directly impacting the third microphone 1251, thereby extending the service life of the third microphone 1251. The first central axis and the second central axis may be perpendicular to the protective net 1252.

[0153] As an example, in combination with Figures 12 and 14, the orthographic projection of the first channel section 12171 on the protective net 1252 and the orthographic projection of the second channel section 12172 on the protective net 1252 can partially overlap, so that the first central axis of the first channel section 12171 and the second central axis of the second channel section 12172 do not coincide.

[0154] Furthermore, the cross-sectional area of ​​the second channel section 12172 on a reference plane perpendicular to the first central axis can be larger than the cross-sectional area of ​​the first channel section 12171 on a reference plane perpendicular to the second central axis. For example, the first channel section 12171 and the second channel section 12172 are each cylindrical holes, with the aperture of the first being smaller than the aperture of the second. In this way, the sound pickup channel 1217 is generally horn-shaped, allowing more sound to enter the sound pickup channel 1217 and be better collected before entering the third microphone 1251.

[0155] It should be noted that: in the process of manufacturing the shell component 121 by a method such as injection molding, the first channel section 12171 and the second channel section 12172 can be formed on the shell component 121 respectively through two cores, and the demolding directions of the two cores are opposite to each other, so as to obtain the first channel section 12171 and the second channel section 12172 with different cross-sectional areas.

[0156] In some embodiments, the overlapping area between the orthographic projection of the first channel section 12171 on the protective net 1252 and the orthographic projection of the second channel section on the protective net 1252 has an overlapping area, and the orthographic projection of the first channel section 12171 on the protective net 1252 has a projected area. The ratio between the overlapping area and the projected area can be between 0.4 and 0.6. If the ratio is too small, the connection area between the first channel section 12171 and the second channel section 12172 may be too small, hindering sound from entering the third microphone 1251 through the sound pickup channel 1217. If the ratio is too large, the risk of the third microphone 1251 being directly impacted by external droplets or the like may increase.

[0157] In some embodiments, the first and second central axes can be arranged parallel to each other to achieve a more uniform wall thickness for the housing assembly 121 and avoid locally excessive thinness. Referring to FIG14 , the first channel segment 12171 and the second channel segment 12172 partially overlap along the first central axis. The ratio between the dimension of the overlapping portion (e.g., |h1-h2|) and the smaller of the depth of the first channel segment 12171 (e.g., h1 in FIG14 ) or the depth of the second channel segment 12172 (e.g., h2 in FIG14 ) can be between 0.5 and 0.8. If this ratio is too small, the connection area between the first and second channel segments 12171, 12172 may be too small, hindering sound from entering the third microphone 1251 through the sound pickup channel 1217. If this ratio is too large, the housing assembly 121 may be partially excessively thin. It is understandable that in some other embodiments, the first central axis and the second central axis may also be arranged at an angle, so that the length of the sound pickup channel 1217 can be adjusted when the wall thickness of the shell component 121 is constant.

[0158] As an example, in conjunction with Figures 12, 15, and 17, the housing assembly 121 has a first direction, a second direction, and a third direction that are orthogonal to each other. The housing assembly 121 may include a housing 1211 and an end cap 12121 that engage with each other in the first direction. The size of the housing assembly 121 in the second direction may be greater than the size of the housing assembly 121 in the third direction. Based on the above description, the first direction, the second direction, and the third direction may be parallel to the insertion direction D6, the sliding direction D7, and the normal direction D5, respectively. In other words, the housing assembly 121 is configured as a flat structure, which helps to reduce the size of the housing assembly 121 in the normal direction D5.

[0159] As an example, with reference to FIG17 , the housing 1211 includes a first inner wall 12111 and a second inner wall 12112 spaced apart from each other in the second direction. The dimension of the first inner wall 12111 in the first direction may be smaller than the dimension of the second inner wall 12112 in the first direction. That is, the depth of the housing 1211 in the first direction is not uniform throughout, but rather varies. The protective net 1252 may be fixed to the first inner wall 12111, and the third microphone 1251 may be fixed to the protective net 1252. Thus, since the third microphone 1251, protective net 1252, and other related structures are located at a shallower depth within the housing 1211, assembly of the electronic device 10 is simplified. Accordingly, the sound pickup channel 1217 may be located on the side wall of the housing 1211.

[0160] Furthermore, a recessed area 12113 may be formed on the first inner wall 12111, and the sound pickup channel 1217 communicates with the bottom of the recessed area 12113. The protective net 1252 may be secured to the bottom of the recessed area 12113 using double-sided tape or glue. The third microphone 1251 may be at least partially located within the recessed area 12113 and secured to the protective net 1252 using double-sided tape or glue to enhance the drop resistance of the third microphone 1251. Similarly, the third microphone 1251 may be mounted on the flexible circuit board 1253 using surface mount technology, which in turn connects to the circuit board 1221.

[0161] As an example, the first inner wall 12111 can be closer to the middle position of the support assembly 12 than the second inner wall 12112, that is, farther away from the movement module 11, and when worn, the sound pickup channel 1217 can point to the back of the head, which is conducive to increasing the anti-interference ability of the third microphone 1251.

[0162] It should be noted that the improvements related to the sound pickup channel 1217 can also be applied to the sound pickup holes provided on the shell assembly 111 that respectively cooperate with the first microphone 1161 and the second microphone 1162, and will not be repeated here.

[0163] As an example, in conjunction with Figures 15, 17, and 18, the electronic device 10 may include a key assembly 126 connected to the housing assembly 121. The key assembly 126 can press the touch switch 1227 on the circuit board 1221 along a pressing direction (for example, the direction indicated by arrow D8 in Figure 17) under the action of an external force to expand the control functions of the electronic device 10, for example, to realize power on / off of the electronic device 10, and for another example, to realize volume increase / decrease of the electronic device 10. In particular, a recessed area 1218 may be provided on the outside of the housing assembly 121, and a key through-hole 1219 is provided at the bottom of the recessed area 1218; the key assembly 126 may be partially located in the recessed area 1218 and extend into the housing assembly 121 through the key through-hole 1219 to approach the touch switch 1227.

[0164] In some embodiments, the number of button assemblies 126 can be two, one of which is at least used to realize the volume increase of the electronic device 10, and the other is at least used to realize the volume reduction of the electronic device 10. For example: the two button assemblies 126 are respectively used to realize the volume increase / decrease of the electronic device 10, and one of the button assemblies 126 is further reused to realize the power on / off of the electronic device 10. In particular, in conjunction with Figures 17 and 18, the two button assemblies 126 can be respectively arranged in their respective recessed areas 1218, and the two recessed areas 1218 are arranged at intervals, and respectively extend into the housing assembly 121 through their respective button through holes 1219, so that the two button assemblies 126 are independent of each other and do not interfere with each other. Correspondingly, the number of touch switches 1227 can also be two, and they are respectively arranged in a one-to-one correspondence with the two button assemblies 126.

[0165] In some embodiments, the number of the button assembly 126 may be one, for example, to power on / off the electronic device 10 .

[0166] As an example, in conjunction with Figures 15, 17, and 18, the button assembly 126 may include a button 1261 and a sealing ring 1262. The button 1261 may be partially located in the recessed area 1218 and extend into the housing assembly 121 via the button through-hole 1219, so as to allow the button assembly 126 to press the tactile switch 1227 along the pressing direction D8 under the action of an external force. The sealing ring 1262 may be located in the recessed area 1218 and surround the button through-hole 1219 to seal the button through-hole 1219. In addition, since the sealing ring 1262 has a certain amount of compression, the sealing ring 1262 can also provide a certain amount of damping and rebound feel when the user operates the button 1261. The sealing ring 1262 shown in Figure 17 is its form before compression. After compression, it has a certain amount of deformation to elastically support between the button 1261 and the housing assembly 121. Of course, in some other embodiments, a sealing groove for accommodating the sealing ring 1262 may be provided on the side of the button 1261 facing the housing assembly 121 .

[0167] As an example, in combination with Figures 17, 18 and 22, the button 1261 may include an operating part 12611, a connector post 12612 connected to the operating part 12611 and a snap-fit ​​part 12613 connected to the connector post 12612. The operating part 12611 may be at least partially located in the recessed area 1218 and supported on the sealing ring 1262. The connector post 12612 passes through the sealing ring 1262 and the button through hole 1219 and extends into the shell assembly 121. The snap-fit ​​part 12613 is engaged with the inner side wall of the shell assembly 121, that is, the snap-fit ​​part 12613 is located on the inner side of the shell assembly 121 facing the circuit board 1221, so that the button 1261 is snap-fitted and fixed to the shell assembly 121. At this time, the sealing ring 1262 can have a certain compression amount, thereby providing a seal between the button 1261 and the bottom of the recessed area 1218. That is, when the button 1261 is connected to the housing assembly 121, the sealing ring 1262 can be pressed simultaneously, thereby improving the sealing performance of the electronic device 10 at the button through hole 1219, which is simple and reliable. Of course, in some other embodiments, in order to achieve the snap connection and fixation between the button 1261 and the housing assembly 121, the button 1261 may not include the snap portion 12613. For example, an additional stopper such as a snap ring or a latch that is independent of the button 1261 is provided. After the stopper and the button 1261 are assembled, they are located on the inner side of the housing assembly 121 facing the circuit board 1221.

[0168] As an example, in combination with Figures 17 and 22, the connector post 12612 can be arranged in a cylindrical shape, and the end of the connector post 12612 facing away from the operating part 12611 can be provided with at least two slots 12614 extending along the axial direction of the connector post 12612, such as the two shown in Figure 22. The slots 12614 can divide the connector post 12612 along the axial direction of the connector post 12612 into a first column section 12615 close to the operating part 12611 and a second column section 12616 away from the operating part 12611. Among them, the first column section 12615 is continuously arranged along the circumference of the connector column 12612, and the sealing ring 1262 is sleeved on the first column section 12615 so that the sealing ring 1262 can seal the button through hole 1219; the second column section 12616 has connector arms (not marked in Figures 17 and 22) arranged at intervals along the circumference of the connector column 12612, and the number of the snap portions 12613 is the same as the number of the aforementioned connector arms and are connected one by one.

[0169] Furthermore, a first guide surface (not labeled in Figures 17 and 18 ) may be provided on the side of the button through-hole 1219 facing away from the circuit board 1221, and a second guide surface 12617 may be provided on the latch portion 12613. Thus, when the button 1261 is inserted into the housing assembly 121, the second guide surface 12617 cooperates with the first guide surface to bring the connector arms closer together, thereby allowing the latch portion 12613 to pass through the button through-hole 1219.

[0170] By way of example, with reference to FIG17 , the button assembly 126 may include an elastic adapter 1263 connected to the button 1261. The elastic adapter 1263 has a lower hardness than the button 1261. The button 1261 presses the tactile switch 1227 via the elastic adapter 1263, thereby providing a certain degree of damping and rebound when the user operates the button 1261. The button 1261 may be made of polycarbonate or a material blended with at least one of glass fiber and carbon fiber, while the elastic adapter 1263 may be made of silicone, rubber, or the like. Furthermore, a portion of the elastic adapter 1263 may be inserted into the second column 12616, while another portion protrudes from the end of the button 1261 facing the tactile switch 1227, so that the button 1261 presses the tactile switch 1227 via the elastic adapter 1263.

[0171] By way of example, in conjunction with Figures 17 and 18 , the recessed area 1218 may include a first sub-recessed area 12181 and a second sub-recessed area 12182. The first sub-recessed area 12181 is closer to the circuit board 1221 than the second sub-recessed area 12182 in the pressing direction D8. The second sub-recessed area 12182 has a dimension perpendicular to the pressing direction D8 that is larger than the first sub-recessed area 12181 in the direction perpendicular to the pressing direction D8. In short, the recessed area 1218 is divided into two sub-areas in the pressing direction D8, and the key through-hole 1219 is provided at the bottom of the first sub-recessed area 12181. The sealing ring 1262 may be partially located within the first sub-recessed area 12181, and the operating portion 12611 may be at least partially located within the second sub-recessed area 12182. In this way, when the button 1261 moves relative to the shell assembly 121 along the pressing direction D8, the operating part 12611 can be stopped by the bottom of the second sub-recessed area 12182 to avoid over-pressing of the button 1261 and excessive deformation of the sealing ring 1262, thereby controlling the stroke of the button 1261 and extending the service life of the sealing ring 1262.

[0172] Furthermore, on a reference cross section parallel to the pressing direction D8, the side walls of the first sub-recessed area 12181 can be at least partially arc-shaped, so that there is an arc-shaped transition between the bottom of the first sub-recessed area 12181 and its side walls, thereby reducing (or even eliminating) the gap between the sealing ring 1262 and the shell assembly 121, and thereby increasing the sealing effect of the sealing ring 1262 on the key through hole 1219.

[0173] By way of example, in conjunction with Figures 15 to 18 and 22 , a first limiting structure 1271 can be provided within the recessed area 1218, the first limiting structure 1271 being located outside the sealing ring 1262, and a second limiting structure 1272 can be provided on the operating portion 12611. In the non-pressed state of the key assembly 126, when not subjected to external force, the first limiting structure 1271 and the second limiting structure 1272 can partially overlap in the pressing direction D8 and cooperate with each other to limit the position of the key 1261 circumferentially of the key through-hole 1219. This helps maintain the relative position of the key 1261 and the housing assembly 121 circumferentially of the key through-hole 1219, thereby preventing the gap between the operating portion 12611 and the housing assembly 121 in the radial direction of the key through-hole 1219 from being too small or too large. In addition, when the button 1261 moves along the pressing direction D8 relative to the shell assembly 121, the operating part 12611 can be stopped by the first limiting structure 1271, and / or the second limiting structure 1272 can abut against the shell assembly 121 to avoid over-pressing of the button 1261 and excessive deformation of the sealing ring 1262, thereby controlling the stroke of the button 1261 and extending the service life of the sealing ring 1262.

[0174] By way of example, in conjunction with Figures 15 to 18 and 22, the first limiting structure 1271 may include two first limiting blocks 12711 spaced apart in the circumferential direction of the key through-hole 1219, and a blind hole 12712 disposed at the bottom of the recessed area 1218 and located between the two first limiting blocks 12711. The second limiting structure 1272 may include a groove 12721 and a second limiting block 12722 partially located within the groove 12721, wherein the groove 12721 partially thins the operating portion 12611. In the aforementioned non-pressed state, the second limiting block 12722 is located between the two first limiting blocks 12711. When the key assembly 126 is in a pressed state under the action of an external force, the second limiting block 12722 extends into the blind hole 12712, and the two first limiting blocks 12711 extend into the groove 12721, respectively. This not only limits the position of the button 1261 circumferentially along the button through-hole 1219, but also helps reduce the size of the housing assembly 121 in the pressing direction D8 when the button assembly 126 has a predetermined stroke. Accordingly, the first limit block 12711 can be located within the second sub-recessed area 12182, and the blind hole 12712 can extend to the bottom of the first sub-recessed area 12181, so that the blind hole 12712 is sufficiently deep, thereby ensuring that the button assembly 126 has a sufficient stroke.

[0175] In some embodiments, the spacing between the two first limit blocks 12711 in the circumferential direction of the key through hole 1219 may be greater than the aperture of the blind hole 12712 in the circumferential direction of the key through hole 1219, and the blind hole 12712 is provided with a guide arc surface or a guide inclined surface on the edge near the first limit block 12711 to facilitate the second limit block 12722 to extend into the blind hole 12712.

[0176] In some embodiments, the spacing between the two first limiting blocks 12711 in the circumferential direction of the button through hole 1219 can be equal to the aperture of the blind hole 12712 in the circumferential direction of the button through hole 1219, so that the second limiting block 12722 can extend into the blind hole 12712.

[0177] By way of example, with reference to Figures 15 to 18 and 22, the number of the first limiting structures 1271 and the second limiting structures 1272 can be two, respectively, and the two first limiting structures 1271 and the second limiting structures 1272 are respectively arranged with relative spacing in the radial direction of the key through-hole 1219. This not only helps to further maintain the relative position of the key 1261 and the housing assembly 121 in the circumferential direction of the key through-hole 1219, but also helps to control the travel of the key 1261 more smoothly.

[0178] As an example, with reference to Figures 15, 17, and 18, the recessed area 1218 and the button through-hole 1219 can be located at the bottom of the housing 1211 relative to the end cover 12121, so that structural components such as the button assembly 126 are fixed to the bottom of the housing 1211, so that the user can operate the button assembly 126 when wearing the housing. Of course, in other embodiments, the relative positions of the bottom of the housing 1211 and the end cover 12121 can be interchanged, so that the recessed area 1218 and the button through-hole 1219 can be provided on the end cover 12121, that is, structural components such as the button assembly 126 can be fixed to the end cover 12121.

[0179] Based on the above description, the housing assembly 121 can serve as part of the support assembly 12 and can be used to accommodate related structural components such as the circuit board 1221 and the battery. Referring to Figure 1 , there can be two housing assemblies 121, one of which can accommodate the circuit board 1221 and the other of which can accommodate the aforementioned battery. Accordingly, the movement module 11 and the aforementioned structural components, such as the battery, can be electrically connected to the circuit board 1221.

[0180] As an example, in conjunction with Figures 23 and 24, the vibration panel 113 can protrude a preset distance relative to the shell assembly 111 along the vibration direction of the transducer 112 (for example, the direction indicated by arrow D1 in Figure 23) when the transducer 112 is in a non-vibrating state. Similarly, the face-fitting assembly 114 may include a face-fitting cover 1141, which covers the vibration panel 113 so that the vibration panel 113 contacts the user's skin through the face-fitting cover 1141. The face-fitting cover 1141 may include a central portion 11415, a transition portion 11416 connected to the central portion 11415, and a fixing portion 11417 connected to the transition portion 11416. The central portion 11415 covers the vibration panel 113, and the fixing portion 11417 is connected to the shell assembly 111 so that the face-fitting cover 1141 covers the vibration panel 113. Furthermore, at least the transition portion 11416 in the face cover 1141 can be a flexible woven fabric, so that the face cover 1141 has a certain degree of deformation ability at least in the area where the transition portion 11416 is located. At this time, after the face cover assembly 114 is assembled to the movement module 11, the aforementioned preset distance makes the transition portion 11416 in a tensioned state under the support of the vibration panel 113. In this way, since the face cover 1141 has a certain degree of deformation ability at least in the area where the transition portion 11416 is located, and the transition portion 11416 is in a tensioned state under the support of the vibration panel 113, not only can the face cover 1141 be smoothly covered on the vibration panel 113, but also the face cover 1141 and the vibration panel 113 have good synchronization during the vibration process.

[0181] As an example, referring to Figures 23 to 26, before the face assembly 114 is assembled to the movement module 11, the face cover 1141 can be a planar structure to facilitate manufacturing of the face cover 1141. After the face assembly 114 is assembled to the movement module 11, the transition portion 11416 can be deformed into a corresponding frustum-shaped tubular structure. In this way, the face cover 1141 not only does not require pre-deformation but also has good adaptability. That is, the shape of the transition portion 11416 after deformation changes with parameters such as the shape and size of the vibration panel 113 and the spacing between the vibration panel 113 and the housing assembly 111 in the vibration direction D1 and in a direction perpendicular to the vibration direction D1.

[0182] In some embodiments, the central portion 11415 and the transition portion 11416 can be formed as a single structural member from the aforementioned flexible braid. When the transducer 112 is in a non-vibrating state, the central portion 11415 is in tension along the vibration panel 113 and deforms as the transducer 112 vibrates. This further facilitates ensuring that the face cover 1141 lies evenly on the vibration panel 113 and that the face cover 1141 and the vibration panel 113 maintain good synchronization during vibration. Furthermore, the fixing portion 11417 and the transition portion 11416 can also be formed as a single structural member from the aforementioned flexible braid, ensuring that the face cover 1141 is formed from the aforementioned flexible braid.

[0183] In some embodiments, the center portion 11415 can be made of silicone, rubber, etc., so that the face cover 1141 can be in contact with the user's skin; the fixing portion 11417 can be made of polycarbonate or at least one of glass fiber and carbon fiber mixed therein, so that the face cover 1141 can be connected to the shell assembly 111.

[0184] As an example, in conjunction with Figure 26, the face cover 1141 can be formed as an integral structural member by the above-mentioned flexible braid. Among them, the above-mentioned flexible braid can be woven from nylon thread, metal wire, etc., so that the face cover 1141 not only has good structural strength, but also has a certain deformation ability. Furthermore, the above-mentioned flexible braid can make the face cover 1141 arranged in a grid shape, so that the face cover 1141 has a certain breathability. In this way, similar to the embodiment described in Figures 2 to 8, the embodiment described in Figures 23 to 26 is also conducive to reducing the sound leakage of the movement module 11 in the far field; unlike the embodiment described in Figures 2 to 8, the embodiment described in Figures 23 to 26 not only does not require the additional setting of the connecting hole 11414, but also can provide fewer (or even no) above-mentioned channels such as the connecting hole 11112. In other words, the embodiment described in Figures 23 to 26 provides a face-fitting component 114 that is different in structure from but similar in function to the embodiment described in Figures 2 to 8. It is worth noting that: since the central portion 11415 mainly affects the comfort of the face cover 1141 in contact with the user's skin because it covers the vibration panel 113, the transition portion 11416 mainly affects the breathability of the face cover 1141 because it does not cover the vibration panel 113, and the fixed portion 11417 mainly affects the reliability of the face cover 1141 because it is connected to the shell assembly 111, the porosity and / or pore size of the face cover 1141 at the transition portion 11416 can be respectively greater than the porosity and / or pore size of the face cover 1141 at the central portion 11415, and the porosity and / or pore size of the face cover 1141 at the fixed portion 11417. For example, the face cover 1141 is woven more densely at the central portion 11415 and the fixed portion 11417 and more sparsely at the transition portion 11416.

[0185] It should be noted that: in the face-fitting cover 1141 shown in Figure 26 (a), the warp and weft threads of the above-mentioned flexible fabric can have a larger displacement under the action of external force; while in the face-fitting cover 1141 shown in Figure 26 (b), the warp and weft threads of the above-mentioned flexible fabric can have a smaller displacement under the action of external force.

[0186] As an example, with reference to Figures 23 to 25 , face-mounted assembly 114 may include a first annular member 1144 connected to a fixing portion 11417. For example, fixing portion 11417 and first annular member 1144 may be adhesively bonded. The hardness of first annular member 1144 may be greater than the hardness of fixing portion 11417. First annular member 1144 is connected to housing assembly 111. In other words, face-mounted assembly 114 may increase local structural strength through first annular member 1144 and be connected to housing assembly 111 through first annular member 1144.

[0187] By way of example, with reference to Figures 23 to 25 , the face-mounting assembly 114 may include a second annular member 1145 connected to the fixing portion 11417. The hardness of the second annular member 1145 may be greater than that of the fixing portion 11417. The second annular member 1145 may be located inside the first annular member 1144, and the second annular member 1145 and the first annular member 1144 jointly clamp the fixing portion 11417 from both the inside and outside of the face-mounting sleeve 1141. This helps to increase the reliability of the connection between the first annular member 1144 (and the second annular member 1145) and the face-mounting sleeve 1141, thereby increasing the reliability of the connection between the face-mounting assembly 114 and the housing assembly 111. It is worth noting that: in the process of making the face-fitting component 114, the face-fitting cover 1141 of a preset shape and size can be placed on the second annular member 1145 first, for example, the face-fitting cover 1141 is larger than the second annular member 1145, and then the first annular member 1144 is fastened to the second annular member 1145 from the side of the face-fitting cover 1141 away from the second annular member 1145, so that the second annular member 1145 and the first annular member 1144 jointly clamp the fixing portion 11417 from the inner and outer sides of the face-fitting cover 1141, and then the relative positions of the second annular member 1145, the first annular member 1144 and the face-fitting cover 1141 are adjusted.

[0188] In some embodiments, the first annular member 1144 can be made of plastic, and the second annular member 1145 can be made of metal. The combination of soft and hard structures of the two annular members allows the second annular member 1145 and the first annular member 1144 to better clamp the fixing portion 11417 from both the inside and outside of the face cover 1141. In embodiments where the first annular member 1144 is provided with a snap-fit ​​protrusion 11128 or a snap-fit ​​groove 11443, the plastic component of the first annular member 1144 simplifies the molding of the snap-fit ​​protrusion 11128 or the snap-fit ​​groove 11443.

[0189] In some embodiments, the first annular member 1144 and the second annular member 1145 can be respectively made of metal so that both have sufficient structural strength.

[0190] In some embodiments, the first annular member 1144 and the second annular member 1145 can be respectively made of plastic to reduce manufacturing costs.

[0191] 23 to 25 , the first annular member 1144 may include a first annular main portion 11441 and a first inner edge portion 11442 connected to one end of the first annular main portion 11441, wherein the first inner edge portion 11442 extends inwardly of the first annular main portion 11441. The second annular member 1145 and the first annular main portion 11441 may jointly clamp the fixing portion 11417 from both inside and outside the face cover 1141. The second annular member 1145 may further press the fixing portion 11417 against the first annular main portion 11441, so that the second annular member 1145 and the first annular member 1144 may better jointly clamp the fixing portion 11417 from both inside and outside the face cover 1141.

[0192] 23 to 25 , the second annular member 1145 may include a second annular main body 11451 and a second inner edge 11452 connected to one end of the second annular main body 11451, wherein the second inner edge 11452 extends inwardly of the second annular main body 11451. The second annular main body 11451 may press the fixing portion 11417 against the first annular main body 11441, and the second inner edge 11452 may further press the fixing portion 11417 against the first inner edge 11442, so that the second annular member 1145 and the first annular member 1144 can better clamp the fixing portion 11417 from both the inner and outer sides of the face cover 1141. In addition, since the second annular member 1145 can be made through a flanging process, the outer surface of the second annular member 1145 can form an arc surface. At this time, the face cover 1141 is supported on the arc surface of the second annular member 1145, which is beneficial to avoid stress concentration in the face cover 1141.

[0193] Furthermore, in a direction perpendicular to the vibration direction D1 , the ring width of the second inner edge portion 11452 may be greater than the ring width of the first inner edge portion 11442 .

[0194] In some embodiments, such as those described in connection with Figures 2 to 8, the face-stick assembly 114 can be detachably connected to the shell assembly 111 via the first annular member 1144, so that the user can replace the face-stick assembly 114 with a new one when needed.

[0195] In some embodiments, for example, if the face assembly 114 does not need to be replaced, the face assembly 114 can be non-detachably connected to the housing assembly 111 via the first annular member 1144. For example, the face assembly 114 can press the fixing portion 11417 onto the first annular support 11114 via the first annular member 1144. For another example, the face assembly 114 can press the fixing portion 11417 onto the movement cover 1112 via the first annular member 1144.

[0196] As an example, in conjunction with Figures 23 to 25, the first annular member 1144 can be detachably connected to the movement cover plate 1112. For example, one of the inner annular surface of the first annular member 1144 and the peripheral side surface of the movement cover plate 1112 is provided with a snap protrusion 11128, and the other is provided with a snap groove 11443 for accommodating the snap protrusion 11128. The snap protrusion 11128 and the snap groove 11443 cooperate to enable the first annular member 1144 and the movement cover plate 1112 to be detachably connected, which is simple and reliable. The number of snap protrusions 11128 can be multiple, and the number of snap grooves 11443 can be equal to the number of snap protrusions 11128, and they can correspond one to one.

[0197] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
