Detailed Implementation

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0020] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0021] In this application, the electronic device 10 can be a terminal device with sound-generating function, such as headphones or smart glasses. The electronic device 10 may include a mechanism module 11 and a support component 12. The support component 12 can be connected to the mechanism module 11 to support the mechanism module 11 when worn. The mechanism module 11 can generate mechanical vibration under the action of an excitation signal, and the aforementioned mechanical vibration can be transmitted to the user based on at least one of bone conduction and air conduction. Furthermore, in conjunction with… Figure 1The support component 12 can be configured to support the user's ears and, when worn, to wrap around the back of the user's head. There can be two mechanism modules 11, each connected to one end of the support component 12. Alternatively, in other embodiments, the support component 12 can support the user's ears and bridge of the nose, or wrap around the top of the user's head; these are not listed here. Therefore, the aforementioned wearing position can be a location on the user's cheek near the ear, a location on the side of the ear away from the head, or other physiological parts, which are not listed here.

[0022] As an example, combined Figure 2 and Figure 3 The mechanism module 11 may include a housing assembly 111, a transducer 112, and a vibration panel 113. The transducer 112 is configured to generate mechanical vibration under the action of an excitation signal and is disposed within the housing assembly 111. The vibration panel 113 is connected to the transducer 112 and is used to indirectly contact or directly contact the user's skin to transmit the aforementioned mechanical vibration.

[0023] Furthermore, the mechanism module 11 may include at least a face-fitting component 114 connected to the vibration panel 113. For example, the face-fitting component 114 covers the vibration panel 113 so that the vibration panel 113 comes into contact with the user's skin through the face-fitting component 114, so as to balance the sound quality and wearing comfort of the electronic device 10.

[0024] As an example, combined Figure 2 and Figure 3The movement module 11 may include a first transducer 115, and the transducer 112 can be connected to the housing assembly 111 via the first transducer 115. This is advantageous compared to directly fixing the transducer 112 inside the housing assembly 111, as it helps prevent excessive mechanical vibrations generated by the transducer 112 from being transmitted to the housing assembly 111, thereby reducing sound leakage from the movement module 11. The transducer 112 may include a bracket 1121, a second transducer 1122, a magnetic circuit system, and a coil 1123. The bracket 1121 can be connected to the housing assembly 111 via the first transducer 115, the magnetic circuit system can be connected to the bracket 1121 via the second transducer 1122, and the coil 1123 is connected to the bracket 1121 and extends into the magnetic gap of the magnetic circuit system. Thus, under the action of an excitation signal, the energized coil 1123 generates an Ampere force in the magnetic field of the magnetic circuit system, causing the bracket 1121 to move relative to the magnetic circuit system, i.e., generating mechanical vibration. Furthermore, the aforementioned magnetic circuit system may include a magnetically conductive cover 1124 and a magnet 1125. The magnet 1125 may be fixed to the bottom of the magnetically conductive cover 1124, forming the aforementioned magnetic gap between itself and the sidewall of the magnetically conductive cover 1124. The number of magnets 1125 may be one or more, for example... Figure 2 and Figure 3 The two adjacent magnets 1125 shown are arranged with their same poles facing each other, and a magnetic guide plate can be clamped between them to allow more of the magnetic field lines of the magnets 1125 to pass through the coil 1123. In some embodiments, the magnetic circuit system may include fasteners 1126, which can fix the stacked magnets 1125 and the magnetic guide plate clamped between the magnets 1125, for example, connecting the second transducer 1122, the magnets 1125 and the bottom of the magnetic guide cover 1124 together. Of course, in other embodiments, the magnets 1125 can be fixed to the bottom of the magnetic guide cover 1124 with glue.

[0025] As an example, combined Figure 2 and Figure 3The face-fitting component 114 may include a face-fitting sleeve 1141, which can cover the vibration panel 113. For example, the face-fitting sleeve 1141 is connected to the vibration panel 113 via an adhesive medium 1142, which helps to increase the flatness of the face-fitting sleeve 1141 on the vibration panel 113 and increase the synchronization between the face-fitting sleeve 1141 and the vibration panel 113 during vibration. The adhesive medium 1142 can be configured to allow the face-fitting component 114 to be removed entirely from the vibration panel 113 without damaging the face-fitting component 114 and the vibration panel 113. Thus, the face-fitting component 114 is not only removable, making it convenient for users to replace with a new one when needed, but also avoids breakage because it can be removed entirely, reducing the difficulty of removing the face-fitting component 114 from the movement module 11, thereby improving the portability of replacing the face-fitting component 114.

[0026] As an example, the adhesive medium 1142 can be configured such that the peel force between the face mask 1141 and the vibration panel 113 is between 4N and 12N. If the peel force is too small, that is, the adhesive force is too small, it is easy to cause insufficient flatness of the face mask 1141 on the vibration panel 113 and poor synchronization with the vibration panel 113 during vibration; if the peel force is too large, that is, the adhesive force is too large, it is easy to cause difficulty in removing the face mask assembly 114 from the vibration panel 113 as a whole.

[0027] As an example, the peel force between the adhesive medium 1142 and the face mask 1141 can be greater than the peel force between the adhesive medium 1142 and the vibration panel 113. Thus, during the removal of the face mask 1141 from the vibration panel 113, the adhesive medium 1142 is more likely to be peeled off along with the face mask assembly 114 rather than remaining on the vibration panel 113, thereby reducing the risk of adhesive residue on the vibration panel 113 and facilitating the replacement of a new face mask assembly 114. The material of the adhesive medium 1142 is more likely to be similar to that of the face mask 1141 to increase the adhesion between the adhesive medium 1142 and the face mask 1141.

[0028] As an example, the adhesive medium 1142 can be double-sided tape or cured adhesive. The adhesive layers on both sides of the double-sided tape can be differentiated according to the materials of the face mask 1141 and the vibration panel 113, and the adhesive material can also be selected from materials similar to the face mask 1141. Furthermore, the hardness of the face mask 1141 can be less than the hardness of the vibration panel 113, and the hardness of the adhesive medium 1142 can also be less than the hardness of the vibration panel 113. The vibration panel 113 can be made of polycarbonate or a mixture of at least one of glass fiber and carbon fiber, and the face mask 1141 can be made of silicone, rubber, etc. Therefore, the adhesive can be a silicone-based soft adhesive.

[0029] As an example, the ratio between the area of ​​the adhesive medium 1142 and the area of ​​the vibrating panel 113 can be between 0.8 and 1. For example, the adhesive medium 1142 may cover the entire vibrating panel 113 (commonly known as "full adhesion"), or the adhesive medium 1142 may be in a mesh pattern. If the aforementioned ratio is too small, it may lead to insufficient flatness of the face mask 1141 on the vibrating panel 113 and poor synchronization with the vibrating panel 113 during vibration. It is worth noting that the area of ​​the face mask 1141 is generally larger than the area of ​​the vibrating panel 113. If the area of ​​the adhesive medium 1142 is larger than the area of ​​the vibrating panel 113, then the area of ​​the adhesive medium 1142 that is not in contact with the vibrating panel 113 is not counted as part of the area of ​​the adhesive medium 1142. Furthermore, the ratio between the thickness of the adhesive medium 1142 and the thickness of the face mask 1141 can be between 0.4 and 1.2. If the aforementioned ratio is too small, the adhesive force provided by the adhesive medium 1142 may be insufficient; if the aforementioned ratio is too large, the mechanical vibration generated by the transducer 112 may suffer excessive loss during transmission via the faceplate 1141 and the adhesive medium 1142. Furthermore, the thickness of the adhesive medium 1142 can be less than the thickness of the faceplate 1141. It is worth noting that in embodiments where the thickness of the portion of the faceplate 1141 connected to the vibration panel 113 via the adhesive medium 1142 is not equal to the thickness of the other portion of the faceplate 1141 not connected to the vibration panel 113, when calculating the ratio or magnitude relationship between the thickness of the adhesive medium 1142 and the thickness of the faceplate 1141, the thickness of the faceplate 1141 can specifically refer to the thickness of the portion of the faceplate 1141 connected to the vibration panel 113 via the adhesive medium 1142 (e.g., the main body 11411 mentioned later).

[0030] It should be noted that the electronic device 10 may include several face-fitting components 114, allowing the user to replace them as needed. The adhesive medium 1142 can be pre-fixed to the face-fitting sleeve 1141, meaning the adhesive medium 1142 and the face-fitting sleeve 1141 are integrated. A release liner may be provided on the side of the adhesive medium 1142 that is bonded to the vibration panel 113 to maintain the adhesiveness of the adhesive medium 1142; the user can simply peel off the release liner when replacing the face-fitting component 114. Of course, in some other embodiments, the adhesive medium 1142 may also be independent of the face-fitting sleeve 1141.

[0031] As an example, combined Figures 2 to 4The face-fitting component 114 may include a reinforcing member 1143 connected to the face-fitting sleeve 1141. The hardness of the reinforcing member 1143 is greater than that of the face-fitting sleeve 1141 to increase the local structural strength of the face-fitting component 114. For example, the face-fitting sleeve 1141 is made of silicone, rubber, etc., and the reinforcing member 1143 is made of polycarbonate or mixed with at least one of glass fiber and carbon fiber. The two are integrally molded into a structural component by injection molding. The face-fitting component 114 can be detachably connected to the housing component 111 through the reinforcing member 1143 to prevent the edge area of ​​the face-fitting component 114 from colliding with the housing component 111 during the vibration of the face-fitting component 114 following 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 housing component 111, respectively. Accordingly, the face-fitting component 114 and the housing component 111 enclose a cavity that at least accommodates the transducer 112 and the vibration panel 113. Of course, in other embodiments, such as where the edge region of the face shield 1141 has a sufficiently large safety clearance from the housing assembly 111, the face shield assembly 114 may also omit the reinforcing member 1143, and the edge region of the face shield 1141 may therefore not be connected to the housing assembly 111. Furthermore, in other embodiments, such as where the face shield assembly 114 does not need to be replaced, the face shield assembly 114 may also be configured to be non-removable.

[0032] 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 inside the core housing 1111, and the vibration panel 113 may be at least partially located outside the core housing 1111. The reinforcing member 1143 may be at least partially located inside the open end of the core housing 1111 and may be detachably connected to the core housing 1111 to provide a certain bonding force between the face-fitting assembly 114 and the housing assembly 111.

[0033] In some embodiments, the housing assembly 111 may include a movement housing 1111 and a movement cover 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-fitting assembly 114 and the transducer 112 may be located on opposite sides of the movement cover 1112. Accordingly, the movement cover 1112 is provided with a first clearance hole 11121 that allows the vibration panel 113 to connect with the transducer 112. The reinforcing member 1143 may be at least partially located outside the movement housing 1111 and may be detachably connected to the movement cover 1112 so that there is a certain bonding force between the face-fitting assembly 114 and the housing assembly 111.

[0034] Furthermore, the bottom of the transducer 112 and the core housing 1111 can be in the vibration direction of the transducer 112 (e.g., Figure 3 The transducer 112 is spaced apart in the direction indicated by the middle arrow D1 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 by a certain threshold distance in the vibration direction of the transducer 112. This ensures that the thickness of the movement housing 1111 meets the requirements while mitigating extreme conditions such as drops or collisions to the movement module 11.

[0035] As an example, combined Figures 5 to 8 One of the open end and the flange portion 11432 of the movement housing 1111 may be provided with a snap-fit ​​protrusion 11111, and the other may be provided with a snap-fit ​​groove 11434 for accommodating the snap-fit ​​protrusion 11111. The snap-fit ​​protrusion 11111 is embedded in the snap-fit ​​groove 11434, that is, the two cooperate to make the reinforcing member 1143 and the movement housing 1111 detachably connected, which is simple and reliable. The number of snap-fit ​​protrusions 11111 can be multiple, for example... Figure 8 The number of the four shown; the number of the snap-fit ​​grooves 11434 can be equal to the number of the snap-fit ​​protrusions 11111, for example Figure 6 The four shown correspond one-to-one.

[0036] As an example, combined Figure 5 and Figure 6 The reinforcing member 1143 may include an annular body portion 11431 and a flange portion 11432 connected to the annular body portion 11431. The face mask 1141 may be connected to at least the annular body portion 11431, for example, by injection molding. The number of flange portions 11432 may be multiple, for example... Figure 6 The four or more flange portions 11432 shown are spaced apart circumferentially on the annular main body portion 11431. Correspondingly, the flange portions 11432 are detachably connected to the movement housing 1111 to achieve a detachable connection between the reinforcing member 1143 and the movement housing 1111. Further, the reinforcing member 1143 may include a protrusion 11433 connected to the annular main body portion 11431, and the face mask 1141 may be further connected to the protrusion 11433, which helps to increase the connection area between the face mask 1141 and the reinforcing member 1143, thereby increasing the bonding strength between the two. The number of protrusions 11433 can be multiple, for example... Figure 6 The eight or more protrusions 11433 shown are spaced apart in the circumferential direction of the annular body portion 11431. For example, multiple flange portions 11432 and multiple protrusions 11433 are alternately spaced apart in the circumferential direction of the annular body portion 11431.

[0037] Furthermore, the ratio between the area covered by the faceplate 1141 and the surface area of ​​the reinforcing member 1143 can be greater than or equal to 0.8. For example, the annular main body 11431 and the protrusion 11433 are completely covered by the faceplate 1141 to maximize the connection area between the faceplate 1141 and the reinforcing member 1143.

[0038] As an example, combined Figure 2 and Figure 3 , Figure 5 and Figure 6 The face mask 1141 may include an integrally connected main body 11411, transition portion 11412, and covering portion 11413. The main body 11411 and covering portion 11413 may be offset from each other in 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. 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 through an adhesive medium 1142, and the covering portion 11413 may cover the reinforcing member 1143, for example, at least covering the annular main body 11431. Furthermore, the covering portion 11413 can be closer to the transducer 112 in the vibration direction D1 than the main body portion 11411, so that the vibration panel 113 can contact the user's skin through the main body portion 11411. In addition, in embodiments where the face mask 1141 is provided with a connecting hole 11414, for example, the connecting hole 11414 is provided on the transition portion 11412, it is also beneficial to prevent the connecting hole 11414 from being covered by the user's skin.

[0039] Furthermore, on a reference section (e.g., the plane of a paper) parallel to the vibration direction D1, the transition portion 11412 can be curved to increase its deformability. This helps prevent the vibration of the vibration panel 113 from being restricted by the housing assembly 111, especially in embodiments where the middle and edge regions of the faceplate assembly 114 are connected to the vibration panel 113 and the housing assembly 111, respectively. Specifically, in the extension direction from the main body 11411 to the covering portion 11413, the transition portion 11412 can gradually approach the transducer 112 and then gradually move away from it, or the transition portion 11412 can gradually approach the transducer 112 and then remain parallel to the plane where the first transducer plate 115 is located.

[0040] As an example, the mobility margin of the transition section 11412 in the vibration direction D1 can be greater than or equal to the maximum amplitude of the transducer 112. The aforementioned mobility margin can refer to the displacement of the transition section 11412 when it changes from a curved shape to a straight shape.

[0041] As an example, combined Figure 2 and Figure 3 , Figures 5 to 8 The open end of the movement housing 1111 may be provided with a connecting hole 11112. The connecting hole 11112 is located between two adjacent flange portions 11432 in the circumferential direction of the annular main body portion 11431. The connecting hole 11112 connects the inside and outside of the movement module 11 through the channel between the corresponding two flange portions 11432. The number of flange portions 11432 can be multiple, for example... Figure 6 The four shown allow for a possible number of connecting holes 11112, for example... Figure 7 and Figure 8 The four holes shown, namely the connecting holes 11112, can correspond one-to-one with the aforementioned channels. Thus, although the movement housing 1111 generally generates a first sound leakage in the far field under the action of the transducer 112, the air in the cavity formed by the face-fitting assembly 114 and the housing assembly 111 generates a second sound leakage in the far field under the action of the transducer 112 and through the connecting holes 11112 and the aforementioned channels. Furthermore, the phase of the second sound leakage is (close to) the phase of the first sound leakage, but they are out of phase. For example, the absolute value of the phase of the second sound leakage is less than 60° compared to the absolute value of the phase of the first sound leakage, allowing them to cancel each other out of phase in the far field, which helps reduce sound leakage in the far field of the movement module 11. It is worth noting that the connecting hole 11112 can be a complete through hole on the open end of the movement housing 1111, or it can be a notch on the open end of the movement housing 1111.

[0042] Furthermore, the face shield 1141 may be provided with a connecting hole 11414, for example, the connecting hole 11414 may be 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 described again here. It is worth noting that in embodiments where only the connecting hole 11112 is provided to reduce sound leakage in the far field of the mechanism module 11, the face shield 1141 may not have the connecting hole 11414, which helps to prevent sweat and other substances from entering the electronic device 10. Similarly, in embodiments where only the connecting hole 11414 is provided to reduce sound leakage in the far field of the mechanism module 11, the open end of the mechanism housing 1111 may not have the connecting hole 11112, to simplify the structure of the mechanism housing 1111.

[0043] During their long-term research and development, the inventors of this application discovered that although the aforementioned second sound leakage is beneficial for reducing sound leakage in the far field of the movement module 11, the frequency response curve of the aforementioned second sound leakage is relatively disordered, leaving room for optimization. Therefore, in conjunction with... Figure 2 and Figure 3The housing assembly 111 may include a movement cover plate 1112 covering the open end of the movement housing 1111. The face contact assembly 114 and the transducer 112 may be located on opposite sides of the movement cover plate 1112. The movement cover plate 1112 is provided with a first clearance hole 11121 that allows the vibration panel 113 to connect with the transducer 112. The movement cover plate 1112 can divide the cavity formed by the face contact assembly 114 and the housing assembly 111 into two parts. That is, the movement cover plate 1112 and the movement housing 1111 cooperate to form a first cavity, and the face contact assembly 114 and the housing assembly 111 cooperate to form a second cavity. For example, the first cavity and the second cavity are located on opposite sides of the movement cover plate 1112. Further, the transducer 112 may be at least partially located in the first cavity, and the vibration panel 113 may be at least partially located in the second cavity. Accordingly, the movement module 11 is provided with a channel connecting the aforementioned second cavity to the outside of the movement module 11, allowing air in the aforementioned first cavity to form a third leakage sound in the far field under the action of the transducer 112 and through the aforementioned channel. The phase of the aforementioned third leakage sound is opposite to (close to) the phase of the aforementioned first leakage sound. For example, the absolute value of the phase of the aforementioned third leakage sound is less than 60° compared with the absolute value of the phase of the aforementioned first leakage sound, so that the two can cancel each other out of phase in the far field, which is beneficial to reducing the leakage sound of the movement module 11 in the far field. In this way, under the restriction of the movement cover plate 1112, the air in the aforementioned first cavity can be restricted from entering and exiting the movement module 11 to a certain extent, which is beneficial to avoid the frequency response curve of the leakage sound that cancels out of phase with the aforementioned first leakage sound in the far field being too disordered, thereby increasing the leakage sound reduction effect of the movement module 11. Based on the Helmholtz resonator, the area of ​​the aforementioned channels can be made 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 as far as possible to a higher frequency band (e.g., a frequency range greater than 4kHz), which is beneficial to further prevent the aforementioned third leakage sound from being heard by the user.

[0044] As an example, there can be multiple channels, which helps to increase the area of ​​the channels. All of the channels can be located on any one of the structural components such as the face mask 1141, the reinforcing member 1143, and the movement housing 1111; alternatively, some channels can be located on one of the structural components such as the face mask 1141, the reinforcing member 1143, and the movement housing 1111, while others are located on the other of the structural components such as the face mask 1141, the reinforcing member 1143, and the movement housing 1111.

[0045] Furthermore, for any one of the aforementioned channels, the channel can be formed by at least any one of the following embodiments.

[0046] In some embodiments, for example, the reinforcing member 1143 is at least partially located within the open end of the movement housing 1111, and the aforementioned channel may be at least partially provided on the reinforcing member 1143. For example, the flange portion 11432 and the spacing region between two adjacent flange portions 11432 are both located within the open end of the movement housing 1111, the spacing region between two adjacent flange portions 11432 constitutes part of the aforementioned channel, and the connecting hole 11112 constitutes another part of the same channel. As another example, the flange portion 11432 and the spacing region between two adjacent flange portions 11432 are both located within the open end of the movement housing 1111, there is an assembly gap between the faceplate assembly 114 and the movement housing 1111, the spacing region between two adjacent flange portions 11432 constitutes part of the aforementioned channel, and the assembly gap between the faceplate assembly 114 and the movement housing 1111 constitutes another part of the same channel.

[0047] In some embodiments, for example, the reinforcing member 1143 is at least partially located within the open end of the movement housing 1111, and the aforementioned channel may be at least partially provided at the open end of the movement housing 1111. For example, the open end of the movement housing 1111 has a connecting hole 11112, and the side of the faceplate 114 that contacts the movement cover 1112 is provided with an uneven surface, such as a wavy surface with varying heights, so that at least part of the reinforcing member 1143 does not contact the movement cover 1112 to form a reserved gap. Furthermore, there is an assembly gap between the faceplate 114 and the movement housing 1111, and the reserved gap between the faceplate 114 and the movement cover 1112 and the assembly gap between the faceplate 114 and the movement housing 1111 constitute part of the aforementioned channel, and the connecting hole 11112 constitutes another part of the same channel. For example, the open end of the movement housing 1111 is provided with a connecting hole 11112. There are assembly gaps between the face-fitting assembly 114 and the movement housing 1111 and the movement cover plate 1112. The connecting hole 11112 constitutes part of the aforementioned channel, and the assembly gaps between the face-fitting assembly 114 and the movement housing 1111 and the movement cover plate 1112 constitute another part of the same channel.

[0048] In some embodiments, the aforementioned channel can be provided on the face mask 1141, for example, the connecting hole 11414 can serve as the aforementioned channel.

[0049] In some embodiments, for example, the reinforcing member 1143 is at least partially located outside the open end of the movement housing 1111, and the aforementioned channel may be provided only on the reinforcing member 1143. For example, the gap region between two adjacent flange portions 11432 is at least partially located outside the open end of the movement housing 1111, and the gap region between two adjacent flange portions 11432 can serve as the aforementioned channel.

[0050] In some embodiments, for example, the reinforcing member 1143 is at least partially located within the open end of the movement housing 1111, and the aforementioned channel may be at least partially provided at the open end of the movement housing 1111, for example, the connecting hole 11112 serves as the aforementioned channel, and at least part of the reinforcing member 1143 does not contact the movement cover plate 1112, so that the aforementioned first cavity can communicate with the connecting hole 11112 through the gap between the reinforcing member 1143 and the movement cover plate 1112.

[0051] As an example, combined Figure 3 The aforementioned channel can be configured such that the gas flow direction between the second cavity and the outside of the mechanism module 11 (e.g., Figure 3 The direction indicated by the middle arrow D2 intersects with the vibration direction D1. For example, the extension direction of the aforementioned channel does not face the side of the movement module 11 that faces the user's skin when worn. This helps to prevent the aforementioned channel from being covered by the user's skin, thereby allowing the aforementioned third sound leakage and the aforementioned first sound leakage to better cancel each other out of phase in the far field.

[0052] As an example, combined Figure 2 and Figure 3 The movement cover 1112 may include an integrally connected inner top 11122, a connecting portion 11123, and an outer bottom 11124. The inner top 11122 and the outer bottom 11124 are offset from 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 outside the inner top 11122. 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 in the vibration direction D1 than the inner top 11122, which helps to avoid the connecting hole 11112 on the movement housing 1111. Accordingly, combined with... Figure 4 The first clearance hole 11121 can be provided on the inner top 11122.

[0053] As an example, combined Figure 2 and Figure 3The housing assembly 111 may include a sealing membrane 1113 connected to the mechanism cover 1112. The sealing membrane 1113 is provided with a second clearance hole 11131 that allows the vibration panel 113 to connect with the transducer 112. The diameter of the second clearance hole 11131 is smaller than the diameter of the first clearance hole 11121. The sealing membrane 1113 is used to seal the assembly gap of the first clearance hole 11121. The aforementioned assembly gap refers to the gap between the structure formed by the connection between the vibration panel 113 and the transducer 112 and the hole wall of the first clearance hole 11121. The assembly gap can prevent the vibration panel 113 and / or the transducer 112 from colliding with the mechanism cover 1112. Thus, under the constraint of the mechanism cover plate 1112 and the sealing membrane 1113, the air in the first cavity can be restricted from entering and exiting the mechanism module 11 to the greatest extent. This helps to further prevent the frequency response curve of the leakage sound, which cancels out the first leakage sound in the far field, from becoming too disordered, thereby increasing the leakage sound reduction effect of the mechanism module 11. In addition, due to the presence of the sealing membrane 1113, the diameter of the first clearance hole 11121 can be larger, which helps to further avoid the aforementioned collisions. Correspondingly, the vibration panel 113 can be connected to the bracket 1121 through the second clearance hole 11131 and the first clearance hole 11112.

[0054] As an example, combined Figures 2 to 4 The sealing membrane 1113 may include an integrally connected first connecting portion 11132, a folded ring portion 11133, and a second connecting portion 11134, with the folded ring portion 11133 connecting 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 folded ring portion 11133. For example, the first connecting portion 11132 and the second connecting portion 11134 may be annularly arranged, while the folded ring portion 11133 may have a U-shaped cross-section on a reference section parallel to the vibration direction D1, allowing the first connecting portion 11132 and the second connecting portion 11134 to move relative to each other in the vibration direction D1. Correspondingly, a second clearance hole 11131 may be provided on the second connecting portion 11134, meaning the first connecting portion 11132 is located around the second connecting portion 11134. At this time, the first connecting part 11132 can be connected to the mechanism cover plate 1112, and the second connecting part 11134 can be connected to the vibration panel 113 or the transducer 112 to seal the assembly gap of the first clearance hole 11121.

[0055] In some embodiments of this application, the sealing membrane 1113 is a complete membrane structure. It should be noted that in other embodiments of this application, the sealing membrane 1113 may have at least one micropore, for example, the area of ​​the micropore is less than or equal to 2 mm². 2This reduces the pressure difference between the inside and outside of the first cavity while further optimizing the sealing membrane 1113 to reduce sound leakage; that is, the micropores can play a role in pressure relief. Of course, the sealing membrane 1113 may not have micropores. When the structural components such as the movement housing 1111, the movement cover plate 1112, and the sealing membrane 1113 are assembled to form the first cavity, the assembly gaps between the various structural components can play a role in pressure relief.

[0056] Furthermore, the sealing membrane 1113 can be made of materials such as rubber or silicone.

[0057] Furthermore, the folded ring portion 11133 protrudes in the direction away from the transducer 112 in the vibration direction D1, that is, the folded ring portion 11133 extends into the first cavity. In this way, compared to the folded ring portion 11133 extending into the second cavity, droplets, dust, etc. that enter the first cavity through the channel are less likely to accumulate on the folded ring portion 11133, which is beneficial to maintaining the reliability of the sealing membrane 1113.

[0058] As an example, combined Figure 2 and Figure 3 , Figure 9 and Figure 10 The bracket 1121 may include a first bracket 11211, a second bracket 11212, and a suspension 11213. The first bracket 11211 may be connected to the central region of the first vibration transducer 115, for example, the two can be integrally formed as a structural component using a metal insert injection molding process. The second bracket 11212 may be connected to the peripheral region of the second vibration transducer 1122, and the suspension 11213 may be connected to the central region of the second vibration transducer 1122, for example, all three can be integrally formed as a structural component using a metal insert injection molding process. Further, one of the first bracket 11211 and the second bracket 11212 may be provided with a connector post 11214, and the other may be provided with a connector hole 11215 for accommodating the connector post 11214. The connector post 11214 is embedded in the connector hole 11215, thereby connecting the first bracket 11211 and the second bracket 11212. The number of the connecting pins 11214 and the connecting holes 11215 can each be multiple, and they correspond one-to-one, for example... Figure 9 The four shown are described above. Accordingly, the above-described magnetic circuit system is connected to the suspension 11213, for example, fasteners 1126 connect the bottom of the suspension 11213, magnet 1125 and magnetic shield 1124 together, or adhesive is used to bond the suspension 11213, magnet 1125 and magnetic shield 1124 together; 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.

[0059] In some implementations, for example Figure 9The first support 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, so that the vibration panel 113 is connected to the support 1121. Correspondingly, a connector post 11214 may be provided on the second support 11212, and a connector hole 11215 may be provided on the main body 11216.

[0060] In some implementations, for example Figure 10 The first support 11211 may include a main body 11216 and a connector 11217 connected to the main body 11216. The connector 11217 may be cylindrical. The vibration panel 113 is partially embedded in the connector 11217 so that the vibration panel 113 is connected to the support 1121.

[0061] As an example, combined Figures 2 to 4 At least one of the vibration panel 113 and the bracket 1121 can be provided with a support end face corresponding to the surrounding area of ​​the second clearance hole 11131. The sealing film 1113 is fixed on the aforementioned support end face, which is simple and reliable. Among them, for Figure 9 In the embodiment shown, the aforementioned support end face can be at least disposed on the vibration panel 113; while for Figure 10 In the embodiment shown, the aforementioned support end face can be provided at least on the bracket 1121. For example, the end face of the connector 11217 that is not connected to the main body 11216 is the support end face.

[0062] As an example, combined Figures 2 to 4 The bracket 1121 may be provided with a first support end face 11218, for example, the first support end face 11218 is the end face of the connector 11217 that is not connected to the main body 11216. The vibration panel 113 may be provided with a second support end face 1131. The first support end face 11218 and the second support end face 1131 can jointly clamp the second connecting part 11134. In other words, the support end faces of the vibration panel 113 and the bracket 1121, which face each other, jointly clamp the second connecting part 11134. In this way, when the vibration panel 113 is connected to the bracket 1121, the sealing film 1113 can be further pressed onto the bracket 1121, which is simple, reliable, and achieves two goals at once.

[0063] As an example, combined Figure 4A recessed area 11125 may be provided on the side of the mechanism cover plate 1112 opposite to the transducer 112. A first clearance hole 11121 is provided at the bottom of the recessed area 11125. A first connecting part 11132 can be connected to the bottom of the recessed area 11125 and surround the first clearance hole 11121. In this way, the recessed area 11125 can not only play a positioning role during the assembly of the sealing film 1113 and the mechanism cover plate 1112, but also increase the flatness of the cavity wall surface of the first cavity. Correspondingly, the recessed area 11125 can be provided on the inner top 11122.

[0064] Furthermore, the recessed area 11125 may include a first recessed segment 11126 and a second recessed segment 11127. The first recessed segment 11126 is closer to the transducer 112 in the vibration direction D1 than the second recessed segment 11127. The dimension of the second recessed segment 11127 in the direction perpendicular to the vibration direction D1 is larger than the dimension of the first recessed segment 11126 in the same direction. In short, the recessed area 11125 is divided into two segments in the vibration direction D1, and a first clearance hole 11121 is provided at the bottom of the first recessed segment 11126. The first connecting portion 11132 is fixed to the bottom of the first recessed segment 11126.

[0065] In some embodiments, the first connecting portion 11132 can be connected to the bottom of the first recessed section 11126 via double-sided adhesive, and the second recessed section 11127 contains adhesive, which helps to increase the reliability of the connection between the sealing film 1113 and the movement cover 1112. In other words, the sidewall of the second recessed section 11127 and the first connecting portion 11132 cooperate to form an annular adhesive groove, which helps to avoid adhesive overflow.

[0066] In some embodiments, the first connecting portion 11132 can be connected to the bottom of the first recessed section 11126 by adhesive. Alternatively, in some embodiments, the first connecting portion 11132 can be connected to the second recessed section 11127 by adhesive.

[0067] Based on the above description, the first connecting part 11132 can be fixed to the bottom of the first recessed section 11126 by the first adhesive 11135, so that the sealing film 1113 is connected to the mechanism cover 1112; the second connecting part 11134 can be fixed to the end face (i.e., the first support end face 11218) of the insertion part 11217 that is not connected to the main body part 11216 by the second adhesive 11136, so that the sealing film 1113 is connected to the bracket 1121. The vibration panel 113 can further press the sealing film 1113 onto the bracket 1121. Furthermore, the first adhesive 11135 and the second adhesive 11136 can be double-sided tape or glue, respectively. It is worth noting that when the first adhesive 11135 and the second adhesive 11136 are both double-sided adhesives, they can be pre-fixed to the sealing film 1113 respectively; and when the first adhesive 11135 and the second adhesive 11136 are both glues, they can be pre-fixed to the mechanism cover 1112 and the bracket 1121 respectively. Furthermore, without considering processing errors, assembly errors, etc., the first support end face 11218 and the bottom of the first recessed section 11126 can be flush in the vibration direction D1.

[0068] As an example, combined Figure 2 and Figure 3 , Figure 7 and Figure 8 The movement housing 1111 may include a first cylindrical sidewall 11113 and a first annular support 11114 connected to the inner wall surface of the first cylindrical sidewall 11113. The outer bottom 11124 may be supported on the first annular support 11114, and the reinforcing member 1143 may be located between the inner wall surface of the first cylindrical sidewall 11113 and the outer wall surface of the connecting portion 11123. Accordingly, one of the snap-fit ​​protrusion 11111 and the snap-fit ​​groove 11434 may be provided on the first cylindrical sidewall 11113, and the other may be provided on the reinforcing member 1143. For ease of description, the snap-fit ​​protrusion 11111 or snap-fit ​​groove 11434 provided on the first cylindrical sidewall 11113 can be further defined as a snap-fit ​​portion. That is, the aforementioned snap-fit ​​portion can be provided on the inner wall surface of the first cylindrical sidewall 11113, so that the face-fitting assembly 114 can engage with the aforementioned snap-fit ​​portion through the flange portion 11432. Similarly, the connecting hole 11112 can also be provided on the first cylindrical sidewall 11113. Furthermore, the mechanism cover plate 1112 can press the edge area of ​​the first vibration transmission plate 115 onto the first annular support 11114.

[0069] Furthermore, multiple columns 11115 can be provided on the first annular support 11114, for example... Figure 8As shown, the six movement cover plates 1112 can be supported on the first annular support 11114 and can be inserted and engaged with the columns 11115. The columns 11115 play a positioning role at least during the assembly of the movement cover plates 1112 and the movement housing 1111. Correspondingly, the outer bottom 11124 can be supported on the first annular support 11114 and can be inserted and engaged with the columns 11115. Among them, the multiple columns 11115, multiple latching parts (such as latching protrusions 11111, which will not be described in detail below) and multiple connecting holes 11112 can be respectively arranged at intervals in the circumferential direction of the first cylindrical sidewall 11113. The multiple latching parts and multiple connecting holes 11112 are staggered from each other in the circumferential direction of the first cylindrical sidewall 11113 so that the three are reasonably distributed. Furthermore, at least two of the plurality of uprights 11115 and at least two of the plurality of connecting holes 11112 may overlap at least partially in a one-to-one correspondence in the circumferential direction of the first cylindrical sidewall 11113, such that the uprights 11115 are located between two adjacent snap-fit ​​portions.

[0070] As an example, the column 11115 can be a heat-fused column to further fix the mechanism cover 1112 onto the first annular support 11114. Figure 2 and Figure 3 , Figure 7 and Figure 8 The column 11115 shown is in its form before heat fusion. After heat fusion, it generally does not exceed the corresponding connecting hole 11112 to avoid interfering with the air entering and exiting the first cavity.

[0071] As an example, combined Figure 7 and Figure 8 The housing assembly 111 has a major axis that is perpendicular to the vibration direction D1 and orthogonal to each other (e.g., Figure 8 (in the direction indicated by the middle arrow D3) and the minor axis (e.g.) Figure 8 (In the direction indicated by the middle arrow D4), the dimension of the first annular support 11114 on the major axis D3 can be larger than the dimension of the first annular support 11114 on the minor axis D4. For example, the first annular support 11114 can be arranged in a racetrack shape. Multiple columns 11115 can be symmetrically arranged on both sides of the major axis D3 and the minor axis D4 to increase the reliability of the connection between the movement cover 1112 and the movement housing 1111. Similarly, multiple snap-fit ​​parts can be symmetrically arranged on both sides of the major axis D3 and the minor axis D4 to increase the reliability of the faceplate assembly 114 and the movement housing 1111.

[0072] As an example, combined Figure 7 and Figure 8The multiple columns 11115 and multiple snap-fit ​​parts can be staggered, which helps to avoid demolding interference in molding processes such as injection molding. Accordingly, in the circumferential direction of the first cylindrical sidewall 11113, a connecting hole 11112 can be provided at intervals between any two adjacent snap-fit ​​parts, so that the size of the connecting hole 11112 in the circumferential direction of the first cylindrical sidewall 11113 is as large as possible.

[0073] As an example, combined Figure 7 and Figure 8 Observing along the vibration direction D1, the connecting holes 11112 can be divided into four groups. Two groups of connecting holes 11112 can be arranged opposite each other on the major axis D3, and the remaining two groups of connecting holes 11112 can be arranged opposite each other on the minor axis D4. This helps to reduce the standing waves in the aforementioned first cavity. Although... Figure 7 and Figure 8 Each group of connecting holes 11112 has only one connecting hole 11112, but 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 elaborated here.

[0074] As an example, combined Figure 2 , Figure 3 and Figure 11 The mechanism module 11 may include a microphone assembly 116, which is disposed within the housing assembly 111. The microphone assembly 116 can pick up at least one of ambient sound, user voice, or other sounds. Further, the microphone assembly 116 may include a first microphone 1161, which, when projected orthographically onto the transducer 112 along the vibration direction D1, falls onto the transducer 112. For example, the first microphone 1161 may be fixed to the bottom of the housing assembly 111 and spaced apart from the transducer 112 along the vibration direction D1. The mechanism module 11 may further include a limiting member 117 disposed within the housing assembly 111. The limiting member 117 is used to stop the transducer 112 when the movement amplitude of the transducer 112 along the vibration direction D1 exceeds a preset amplitude threshold, so that the transducer 112 and the first microphone 1161 maintain a predetermined distance. This helps to prevent the first microphone 1161 from being damaged by the transducer 112, especially under extreme conditions such as drops or collisions of the mechanism module 11.

[0075] Furthermore, the aforementioned amplitude threshold can be greater than the maximum amplitude of the transducer 112 when the mechanism module 11 is working 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 limiting member 117 or other structures to avoid noise from the mechanism module 11.

[0076] In some embodiments, the limiting member 117 may be arranged in a ring shape or a block shape. The center of the limiting member 117 may be aligned with the center of the transducer 112 in the vibration direction D1, so that the force distribution when the limiting member 117 stops the transducer 112 is more uniform. In some embodiments of this application, the limiting member 117 may be arranged adjacent to the first microphone 1161 to better prevent the first microphone 1161 from being damaged by the transducer 112, especially under extreme conditions such as drops or collisions to the core module 11. The adjacent arrangement of the limiting member 117 and the first microphone 1161 means that in the direction of the line connecting the center of the limiting member 117 and the center of the first microphone 1161, the distance between the limiting member 117 and the first microphone 1161 is at least less than half the dimension of the transducer 112 in that direction. For example, the adjacent arrangement of the limiting member 117 and the first microphone 1161 means that, along the line connecting the center of the limiting member 117 and the center of the first microphone 1161, the distance between the limiting member 117 and the first microphone 1161 is at least less than 1 / 2, 1 / 3, 1 / 4, 1 / 5, etc., of the dimension of the transducer 112 in that line direction. In some embodiments, the limiting member 117 can be made of polycarbonate or at least one of glass fiber and carbon fiber mixed therein. Alternatively, the limiting member 117 can also be made of silicone, rubber, sponge, or other elastic materials, which can provide a certain buffer when the transducer 112 collides with the limiting member 117, thus avoiding or mitigating potential damage to the transducer 112. It is understood that, in this application, the limiting member 117 can also be made of any other type of material, and this application does not specifically limit it. The limiting member 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 can be integrally formed structural components.

[0077] As an example, combined Figure 2 The limiting member 117 and the first microphone 1161 can be configured to remain relatively fixed, for example, both can be fixed to the bottom of the mechanism housing 1111, or the limiting member 117 can be part of the mechanism housing 1111 and the first microphone 1161 can be fixed to the bottom of the mechanism housing 1111. The orthographic projection of the transducer 112 along the vibration direction D1 covers the first microphone 1161 and the limiting member 117, so that the limiting member 117 can stop the transducer 112. Furthermore, in the vibration direction D1, the side of the limiting member 117 facing the transducer 112 is higher than the side of the first microphone 1161 facing the transducer 112, to prevent the first microphone 1161 from being damaged by the transducer 112.

[0078] In some other embodiments, the limiting member 117 and the first microphone 1161 can both be fixed to the bottom of the housing assembly 111, with the limiting member 117 fixed to the transducer 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 limiting member 117 facing the bottom of the housing assembly 111 and the bottom of the housing assembly 111 is less than the distance between the side of the first microphone 1161 facing the transducer 112 and the transducer 112, to prevent the first microphone 1161 from being damaged by the transducer 112.

[0079] As an example, combined Figure 2 and Figure 3 The microphone assembly 116 may include a second microphone 1162 and a flexible circuit board 1163 connecting the first microphone 1161 and the second microphone 1162. The second microphone 1162 is fixed to the side wall of the housing 1111. The housing 1111 may have a wiring groove, and the flexible circuit board 1163 is fixed within this groove. This wiring groove serves to position the flexible circuit board 1163 during assembly with the housing 1111; it also prevents glue overflow when the two are glued together. Since the flexible circuit board 1163 is fixed within the wiring groove, the area containing the flexible circuit board 1163 can be simply considered as the wiring groove. Furthermore, the limiting member 117 and the wiring groove are offset from each other to avoid interference during processing. Correspondingly, the housing 1111 may have pickup holes that respectively cooperate with the first microphone 1161 and the second microphone 1162.

[0080] As an example, combined Figure 11The flexible circuit board 1163 may include an integrally connected first flexible circuit section 11631 and a second flexible circuit section 11632. The first microphone 1161 may be mounted on the end of the first flexible circuit section 11631 away from the second flexible circuit section 11632 using surface mount technology (SMT), and the second microphone 1162 may also be mounted on the end of the second flexible circuit section 11632 away from the first flexible circuit section 11631 using SMT, thereby forming a microphone assembly 116 for easy assembly. The angle between the orthographic projection of the first flexible circuit section 11631 on a reference plane (e.g., a paper surface) perpendicular to the vibration direction D1 and the orthographic projection of the second flexible circuit section 11632 on the aforementioned reference plane may be greater than 90° and less than 180°, i.e., 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 within the housing assembly 111, thereby increasing the distance between the two microphones and improving the sound pickup effect of the microphone assembly 116.

[0081] As an example, combined Figure 2 and Figure 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. A portion of the second cylindrical sidewall 11116 extends into the first cylindrical sidewall 11113, so that the first cylindrical sidewall 11113 is supported on the second annular support 11118. The overlapping portions of the first cylindrical sidewall 11113 and the second cylindrical sidewall 11116 may be provided with a snap-fit ​​structure to secure them together. The second annular support 11118 may be provided with an adhesive groove to bond the first cylindrical sidewall 11113 to the second annular support 11118, thereby increasing the reliability of the connection between the first cylindrical sidewall 11113 and the second cylindrical sidewall 11116. Accordingly, 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 aforementioned wiring groove can be partially opened on the bottom wall 11117 and partially opened on the second cylindrical side wall 11116; the limiting member 117 can be fixed on the bottom wall 11117 or as part of the structure of the bottom wall 11117.

[0082] Based on the above description, the mechanism 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, such 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 can be fixed inside the second housing, and the second housing is relatively shallow, which helps to reduce the assembly difficulty of 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 difference between the first cylindrical sidewall 11113 and the second cylindrical sidewall 11116. The hardness of the flexible covering 1114 may be less than the hardness of the movement housing 1111.

[0083] As an example, combined Figure 12 , Figure 15 and Figure 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 being supported on one side of the circuit board 1221. The housing assembly 121 may include a housing 1211 and a lampshade 1222 disposed within the side wall of the housing 1211. The antenna bracket 123 and the circuit board 1221 are at least partially housed within the housing 1211, and the antenna bracket 123 may be located on the side of the circuit board 1221 facing the lampshade 1222. Furthermore, an indicator light 1223 can 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 components. The light guide portion 1232 is configured to guide the light emitted by the indicator light 1223 to the outside of the electronic device 10. For example, the light emitted by the indicator light 1223 propagates through the light guide portion 1232 to the lampshade 1222 and then exits to the outside of the electronic device 10. In this way, even if the distance between the indicator light 1223 and the lampshade 1222 is relatively large due to the presence of the antenna bracket 123, the light loss emitted by the indicator light 1223 is reduced under the guidance of the light guide portion 1232. This eliminates the need for the indicator light 1223 to increase its luminous power, thereby reducing the power consumption of the indicator light 1223 and extending its service life.

[0084] In some embodiments, the outer surface of the light guide 1232 may be coated with a reflective coating or have a textured surface. The light is refracted inside the light guide 1232, reducing light leakage from the side of the light guide 1232 and improving the light utilization rate. Specifically, the light-incident surface of the light guide 1232 facing the indicator light 1223 and the light-exit surface facing the lampshade 1222 need to be exposed, for example, without a reflective coating or a textured surface, to allow light to pass through the light guide 1232.

[0085] As an example, combined Figure 12 , Figure 15 and Figure 21 The center of the lampshade 1222's orthographic projection on the circuit board 1221 may not coincide with the center of the indicator light 1223, meaning the lampshade 1222 is offset relative to the indicator light 1223, allowing for more flexible placement of the lampshade 1222. Specifically, in the normal direction of the circuit board 1221 (e.g., ... Figure 12 and Figure 15 In the direction indicated by the middle arrow D5, the cross-sectional area of ​​the end of the light guide 1232 near the circuit board 1221 can be larger than the cross-sectional area of ​​the other end of the light guide 1232 near the lampshade 1222, so as to change the light path of the light emitted by the indicator light 1223 and make the light emitted by the indicator light 1223 reaching the lampshade 1222 more focused. Of course, the center of the orthographic projection of the lampshade 1222 on the circuit board 1221 can also coincide with the center of the indicator light 1223.

[0086] As an example, combined Figure 12 The end face of the light guide 1232 facing the indicator light 1223 can be configured as an arc surface that is recessed inside the light guide 1232, similar to a concave structure, so as to better concentrate the light emitted by the indicator light 1223.

[0087] As an example, combined Figure 12 and Figure 21 The antenna bracket 123 may include a connecting rib 1233 connecting the light guide portion 1232 and the antenna support portion 1231, that is, the light guide portion 1232 is connected to the antenna support portion 1231 through the connecting rib 1233. Further, 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 can be between 0.3 and 0.5. If the aforementioned ratio is too small, the connection strength between the light guide portion 1232 and the antenna support portion 1231 may be insufficient; if the aforementioned ratio is too large, excessive light emitted by the indicator light 1223 may leak through the connecting rib 1233 to the antenna support portion 1231.

[0088] In some embodiments, the antenna support 1231, the light guide 1232, and the connecting rib 1233 can be integrally molded structural parts made of the same material, for example, integrally molded by injection molding.

[0089] In some embodiments, the antenna support 1231 and the light guide 1232 can be integrally molded structural components made of different materials, for example, integrally molded by a two-color injection molding process. The connecting rib 1233 can be part of either the antenna support 1231 or the light guide 1232.

[0090] As an example, combined Figure 12 , Figure 17 and Figure 21 An antenna pattern 1224 can be provided on the side of the antenna support 1231 facing away from the circuit board 1221. The antenna pattern 1224 can abut against the circuit board 1221 through a metal elastic member 1225 to achieve electrical contact. The antenna pattern 1224 can be located on the side of the antenna support 1231 facing the lampshade 1222 to increase the distance between the antenna pattern 1224 and the circuit board 1221, thus increasing the antenna clearance area and improving the anti-interference capability of the antenna pattern 1224. Furthermore, the antenna pattern 1224 can be formed on the antenna support 1231 using laser-direct-structuring (LDS) technology, or it can be a flexible circuit board pasted onto the antenna support 1231. The metal elastic member 1225 can be a pogo pin or a metal spring, etc., without limitation. Furthermore, the metal elastic member 1225 can be fixed to the circuit board 1221.

[0091] It should be noted that: combination Figure 1 and Figure 12 In the wearing state, the lampshade 1222 can be positioned further outward than the circuit board 1221, so that the light emitted by the indicator light 1223 and guided by the light guide portion 1232 and the lampshade 1222 is not blocked. Similarly, in the wearing state, the antenna pattern 1224 can be positioned further outward than the circuit board 1221, for example, the antenna pattern 1224 can be located between the circuit board 1221 and the lampshade 1222, to further increase the anti-interference capability of the antenna pattern 1224. Furthermore, in some other embodiments, the electronic device 10 may not include the antenna bracket 123, for example, the antenna pattern 1224 may be disposed on the housing assembly 121 or on the circuit board 1221, or the lampshade 1222 may extend further into the housing assembly 121 to shorten the distance between it and the indicator light 1223.

[0092] As an example, combined Figure 21The antenna bracket 123 may include positioning posts 1234 and latching parts 1235 connected to the antenna support part 1231. The positioning posts 1234 play a positioning role during the assembly of the antenna bracket 123 and the circuit board 1221, and the latching parts 1235 securely engage the antenna bracket 123 with the circuit board 1221. Multiple positioning posts 1234 and latching parts 1235 can be present. After multiple positioning posts 1234 extend into the positioning holes on the circuit board 1221, multiple latching parts 1235 can respectively engage with different sides of the circuit board 1221, making the connection between the antenna bracket 123 and the circuit board 1221 more reliable. It is worth noting that due to the viewing angle, ... Figure 21 Only one positioning post 1234 and one latching part 1235 are shown. Correspondingly, when the antenna bracket 123 is snapped and fixed to the circuit board 1221, the metal elastic element 1225 simultaneously makes electrical contact with the antenna pattern 1224.

[0093] As an example, combined Figure 12 , Figure 15 and Figure 17 The housing assembly 121 may include an end cap 12121 connected to the housing 1211, and the antenna bracket 123 and circuit board 1221 may be together along the insertion direction (e.g. Figure 15 and Figure 17 (In the direction indicated by the middle arrow D6) and at least partially inserted into the housing 1211 via the open end of the housing 1211, with the end cap 12121 further connected to the open end of the housing 1211, so that the circuit board 1221 and the antenna bracket 123 and their structural components are located within the housing assembly 121. Thus, since the lampshade 1222 and the antenna bracket 123 are two separate structural components, they and their associated structural components can be assembled together in a specific assembly sequence, preventing technical problems caused by structural interference during the assembly of the electronic device 10. Accordingly, the light guide 1232 is located between the indicator light 1223 and the lampshade 1222 after the antenna bracket 123 and the circuit board 1221 are assembled.

[0094] Similarly, the end cap 12121 can partially extend into the compartment 1211 and can be supported on a third annular support platform on the inner side of the open end of the compartment 1211. The overlapping portion of the end cap 12121 and the compartment 1211 can be provided with a snap-fit ​​structure to secure them together. The aforementioned third annular support platform can be provided with an adhesive groove to glue the end cap 12121 to the third annular support platform, thus increasing the reliability of the connection between the end cap 12121 and the compartment 1211. Furthermore, the housing assembly 121 can include a flexible covering 12122 covering the outside of the end cap 12121. The outer surface of the flexible covering 12122 can be flush with the outer surface of the compartment 1211 to fill the step difference between the end cap 12121 and the compartment 1211. The hardness of the flexible covering 12122 can be less than the hardness of the end cap 12121. It is worth noting that flexible cladding 12122 and flexible cladding 1114 can be injection-molded integral structural parts.

[0095] As an example, combined Figure 12 and Figure 18 A stepped hole 1213 may be provided on the side wall of the housing 1211, and the lampshade 1222 is assembled in the stepped hole 1213. The lampshade 1222 may include a first light-transmitting part 12221 and a second light-transmitting part 12222 integrally connected, and the radial dimension of the first light-transmitting part 12221 is smaller than the radial dimension of the second light-transmitting part 12222. The stepped hole 1213 may include a first hole segment and a second hole segment that are connected to each other, and the radial dimension of the first hole segment is smaller than the radial dimension of the second hole segment. The first hole segment is closer to the circuit board than the second hole segment in the normal direction D5. The first light-transmitting part 12221 is embedded in the first hole segment, and the second light-transmitting part 12222 is embedded in the second hole segment and 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 the outside to the inside, which helps to prevent the lampshade 1222 from intruding into the compartment 1211 under the action of external force, so as to maintain the relative positional relationship between the lampshade 1222 and the compartment 1211.

[0096] As an example, combined Figure 12 , Figure 18 and Figure 21 The electronic device 10 may include a sliding key assembly 124 connected to the housing assembly 121, the sliding key assembly 124 being able to slide along the sliding direction (e.g., under the action of an external force). Figure 12(As indicated by the middle arrow D7) toggling the toggle switch 1226 on the circuit board 1221 expands the control functions of the electronic device 10, such as enabling the electronic device 10 to power on / off. The sliding key assembly 124 extends from the outside of the housing assembly 121 into the inside of the housing assembly 121 via a groove 1214 on the housing assembly 121, and further connects to the toggle switch 1226 via a clearance groove 1236 on the antenna bracket 123, allowing the user to toggle the toggle switch 1226 using the sliding key assembly 124. Furthermore, a portion of the sliding key assembly 124 can be positioned between the antenna bracket 123 and the housing assembly 121, preventing the sliding key assembly 124 from intruding into the housing assembly 121 under external force and preventing the sliding key assembly 124 from separating from the housing assembly 121.

[0097] As an example, combined Figure 12 , Figures 18 to 21 The sliding key assembly 124 may include an adapter frame 1241 and a sliding key 1242. The sliding key 1242 can be connected to a toggle switch 1226 via the adapter frame 1241 and is used to receive external force applied by the user to actuate 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 of the antenna bracket 123 via a clearance 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 a sliding groove 1214, thereby connecting to the adapter frame 1241. In short, the sliding key 1242 and the adapter frame 1241 can be assembled together. Thus, since the adapter frame 1241 and the sliding key 1242 are two separate structural components, they and their related structural components can be assembled together in a certain assembly sequence, so that the electronic device 10 will not encounter technical problems due to structural interference during assembly. Accordingly, a portion of the adapter 1241 may be positioned between the antenna bracket 123 and the housing assembly 121 to prevent the sliding key assembly 124 from separating from the housing assembly 121 after the sliding key assembly 124 and other structural components are assembled. Of course, in some other embodiments, in order to prevent the sliding key assembly 124 from separating from the housing assembly 121, for example, a portion of the sliding key 1242 may be positioned on the inside of the housing assembly 121 facing the circuit board 1221, or an additional retaining member such as a retaining ring or pin independent of the sliding key 1242 may be provided. After the aforementioned retaining member is assembled with the sliding key 1242, it may be positioned on the inside of the housing assembly 121 facing the circuit board 1221. In order for the sliding key assembly 124 to move the toggle switch 1226, the sliding key assembly 124 may also not include the adapter 1241. For example, the second connector 12422 mentioned later is connected to the toggle switch 1226.

[0098] As an example, combined Figure 12 , Figures 18 to 21 The adapter 1241 may include an annular main body 12411 and a first connector 12412 connected to the annular main body 12411. The annular main body 12411 is located on the side of the antenna bracket 123 opposite to the circuit board 1221. The first connector 12412 passes through the clearance groove 1236 and is connected to the toggle switch 1226. The sliding key 1242 may include an operation part 12421, a second connector 12422 connected to the operation part 12421, and a locking part 1 connected to the second connector 12422. 2423, the operating part 12421 is located on the outside of the housing assembly 121 to receive external force applied by the user. The second insertion part 12422 passes through the slide groove 1214 and extends into the slot 12413 of the annular main body 12411. The engaging part 12423 engages with the side of the annular main body 12411 facing the circuit board 1221, that is, the engaging part 12423 is located on the side of the annular main body 12411 facing the circuit board 1221, so that the sliding key 1242 is engaged and fixed with the adapter 1241. Of course, in some other embodiments, in order to achieve the engagement and fixation of the sliding key 1242 with the adapter 1241, the sliding key 1242 may not include the engaging part 12423. For example, an additional retaining member such as a retaining ring or pin independent of the sliding key 1242 is provided. After the aforementioned retaining member is assembled with the sliding key 1242, it is located on the side of the adapter 1241 facing the circuit board 1221.

[0099] In some embodiments, the length of the annular main body 12411 in the sliding direction D7 may be greater than the length of the clearance groove 1236 in the sliding direction D7, so that the annular main body 12411 can be limited between the antenna support 123 and the housing assembly 121.

[0100] In some embodiments, the width of the annular main body 12411 in the direction perpendicular to the sliding direction D7 and the insertion direction may be greater than the width of the clearance groove 1236 in the direction perpendicular to the sliding direction D7 and the aforementioned insertion direction, so that the annular main body 12411 can be confined between the antenna bracket 123 and the housing assembly 121. The aforementioned insertion direction can be defined as the assembly direction in which the sliding key 1242 and the adapter 1241 are connected, for example, the aforementioned insertion direction is parallel to the extension direction of the second insertion portion 12422.

[0101] Since the length of the annular main body 12411 can be greater than the length of the clearance groove 1236, and the width of the annular main body 12411 can be greater than the width of the clearance groove 1236, the annular main body 12411 can be supported on the antenna bracket 123, especially during the process of connecting the sliding key 1242 to the adapter 1241 along the aforementioned assembly direction, thus simplifying the assembly process. In conjunction with... Figure 12and Figure 21 A limiting groove 1237 can be provided on the side of the antenna bracket 123 away from the circuit board 1221. An avoidance groove 1236 is provided at the bottom of the limiting groove 1237. The annular main body 12411 can be located at least partially within the limiting groove 1237, which helps to reduce the size of the housing assembly 121 in the normal direction D5.

[0102] As an example, combined Figure 12 , Figure 19 and Figure 20 Two sets of second insertion portions 12422 and engaging portions 12423 can be provided at intervals along the sliding direction D7, and the two engaging portions 12423 are at least partially located on opposite sides of the two second insertion portions 12422, so as to facilitate the engagement and fixation of the sliding key 1242 with the adapter frame 1241, and to help prevent relative movement between the sliding key 1242 and the adapter frame 1241. Accordingly, the dimension of the slot 12413 in the sliding direction D7 can be larger than the dimension of the slot 12413 in the direction perpendicular to the sliding direction D7 and the aforementioned insertion 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. Thus, during 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 bring the two sets of second insertion parts 12422 and locking parts 12423 closer together, so that the two locking parts 12423 pass through the slot 12413; correspondingly, after the two locking parts 12423 pass through the slot 12413, the relative position between the two sets of second insertion parts 12422 and locking parts 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 part 12411 in the opposite direction of the sliding key 1242 extending into the adapter frame 1241, thereby realizing the locking and fixing of the sliding key 1242 and the adapter frame 1241. Of course, in some embodiments, only one set of the second connector 12422 and the locking part 12423 may be provided, and a retaining ring may be used to maintain the relative fixation between the sliding key 1242 and the adapter 1241.

[0103] As an example, combined Figure 12 and Figure 17 The extension direction of the switch handle of the toggle switch 1226 can be perpendicular to the normal direction D5, which helps to reduce the size of the housing assembly 121 in the normal direction D5. Accordingly, combined with... Figure 20The number of first connectors 12412 can be two, and the two first connectors 12412 are spaced apart in the sliding direction D7. The switch handle of the toggle switch 1226 is engaged between the two first connectors 12412, so that the adapter 1241 and the switch handle of the toggle switch 1226 are engaged and fixed, thereby facilitating the sliding key 1242 toggle the toggle switch 1226 through the adapter 1241. Of course, in some embodiments, the number of first connectors 12412 can also be one, and the switch handle of the toggle switch 1226 can be provided with a hole to allow the first connector 12412 to partially extend into the aforementioned hole, which also allows the first connector 12412 to connect with the switch handle of the toggle switch 1226.

[0104] As an example, combined Figure 12 and Figure 13 The operating part 12421 may have a sealing groove 12425 surrounding the slide groove 1214 on its inner side facing the circuit board 1221. The sliding key assembly 124 may include a sealing ring 1243 disposed within the sealing groove 12425 to seal the slide groove 1214. Furthermore, because the sealing ring 1243 has a certain amount of compression, it can also provide a certain amount of damping during user operation of the sliding key 1242, resulting in a better sliding feel. Figure 12 and Figure 13 The sealing ring 1243 shown is in its form before compression. After compression, it has a certain deformation to elastically support the sliding key 1242 and the housing assembly 121, and to achieve a good sealing effect on the sliding groove 1214. Of course, in some other embodiments, the sealing groove 12425 can also be provided on the housing assembly 121.

[0105] Because the sealing ring 1243 is elastically supported between the operating part 12421 and the housing assembly 121, the adapter 1241 can be pressed against the housing assembly 121 to prevent the sliding key assembly 124 from shaking relative to the housing assembly 121. This is achieved by combining... Figure 20 The adapter 1241 may include a sliding rib 12415 disposed on the side of the annular main body 12411 opposite to the circuit board 1221. The adapter 1241 is slidably supported on the housing assembly 121 by the sliding rib 12415 to reduce the contact area between the adapter 1241 and the housing assembly 121, thereby reducing the frictional resistance when the sliding key assembly 124 slides relative to the housing assembly 121.

[0106] In some embodiments, the number of sliding ribs 12415 can be multiple, for example Figure 20The two or more sliding ribs 12415 shown can be strip-shaped and located on both sides of the slot 12413 in a direction perpendicular to the sliding direction D7 and the aforementioned insertion direction. Each sliding rib 12415 can extend along the sliding direction D7.

[0107] In some embodiments, the sliding rib 12415 may be arranged in a ring shape and surround the slot 12413.

[0108] As an example, combined Figure 12 , Figure 13 and Figure 18 The outer side of the housing assembly 121 may be provided with a recessed area 1215, and a slide groove 1214 is provided at the bottom of the recessed area 1215. The operating part 12421 may be located at least partially within the recessed area 1215, which is beneficial to reduce the size of the electronic device 10 in the normal direction D5.

[0109] In some embodiments, after the sliding key assembly 124 slides relative to the housing assembly 121 along the sliding direction D7 to the toggle switch 1226 being in the open or closed state, the operating part 12421 can be stopped by the side wall of the recessed area 1215 to prevent the sliding key assembly 124 from being over-pulled.

[0110] In some embodiments, after the sliding key assembly 124 slides relative to the housing assembly 121 along the sliding direction D7 to the toggle switch 1226 in the open or 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-shifted.

[0111] As an example, combined Figure 12 and Figure 13 An annular groove 1216 is provided around the bottom of the recessed area 1215 at the location where it connects to the sidewall of the recessed area 1215, to eliminate the radius (R) at the corner between the bottom of the recessed area 1215 and the sidewall, especially when the housing assembly 121 is manufactured by injection molding. The electronic device 10 may include a pad 1244 attached to the bottom of the recessed area 1215, covering the annular groove 1216, with the edge of the pad 1244 suspended above the annular groove 1216, allowing the pad 1244 to be flatly attached and preventing the edge of the pad 1244 from lifting. Correspondingly, the sliding key assembly 124 can be supported on the pad 1244. Furthermore, because the edge of the pad 1244 does not lift, 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 open or closed state, the edge of the operating part 12421 is located above the annular groove 1216.

[0112] Furthermore, the outer wall of the annular groove 1216 away from the slide groove 1214 can be flush with the side wall of the recessed area 1215.

[0113] In some embodiments, the gasket 1244 may be provided with text, color, symbols, or other indication information to indicate the open or closed state of the toggle switch 1226. For example, the text "ON" and "OFF" may indicate the open and closed states, respectively, and green and red may indicate the open or closed states, respectively. The aforementioned indication information may be located 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 indication information may be located on the bottom of the recessed area 1215.

[0114] In some embodiments, the gasket 1244 can be used to adjust the damping generated by the sealing ring 1243 during the sliding of the sliding key assembly 124 relative to the housing assembly 121 in the sliding direction D7.

[0115] As an example, combined Figure 12 and Figure 18 The stepped hole 1213, the slide groove 1214, and the recessed area 1215 can be located on the same side wall of the compartment 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.

[0116] As an example, combined Figure 12 and Figure 14 The electronic device 10 includes a third microphone 1251 disposed within a 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 may be provided with a sound pickup channel 1217, and the third microphone 1251 is used to pick up sound transmitted through the sound pickup channel 1217. Further, the sound pickup channel 1217 may include a first channel segment 12171 and a second channel segment 12172 that are connected to each other. In some embodiments of this application, the first channel segment 12171 and the second channel segment 12172 are connected, and the interior of the housing assembly 121 is connected to the outside through the first channel segment 12171 and the second channel segment 12172. The first channel segment 12171 is closer to the third microphone 1251 than the second channel segment 12172, and the first central axis of the first channel segment 12171 and the second central axis of the second channel segment 12172 may not coincide. In this way, the first channel segment 12171 and the second channel segment 12172 are staggered with each other, which helps to prevent external droplets from directly impacting the third microphone 1251, thereby extending the service life of the third microphone 1251.

[0117] In other embodiments of this application, the pickup channel 1217 may include three or more channel segments that are interconnected and connect the interior of the housing assembly 121 to the outside.

[0118] Furthermore, the electronic device 10 may include a protective mesh 1252 disposed within the housing assembly 121, which covers the first channel section 12171. This helps to further prevent external droplets or other contaminants 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 mesh 1252.

[0119] As an example, combined Figure 12 and Figure 14 The orthographic projection of the first channel segment 12171 on the protective net 1252 and the orthographic projection of the second channel segment 12172 on the protective net 1252 can partially overlap, so that the first central axis of the first channel segment 12171 does not coincide with the second central axis of the second channel segment 12172.

[0120] Furthermore, the cross-sectional area of ​​the second channel segment 12172 on the reference plane perpendicular to the first central axis can be larger than the cross-sectional area of ​​the first channel segment 12171 on the reference plane perpendicular to the second central axis. For example, the first channel segment 12171 and the second channel segment 12172 are cylindrical holes, with the former having a smaller aperture than the latter. Thus, the pickup channel 1217 is approximately horn-shaped, allowing more sound to enter the pickup channel 1217 and be better focused before entering the third microphone 1251.

[0121] It should be noted that during the manufacturing of the housing assembly 121 by means such as injection molding, a first channel segment 12171 and a second channel segment 12172 can be formed on the housing assembly 121 by two cores respectively, and the demolding directions of the two cores are opposite to each other, so as to obtain a first channel segment 12171 and a second channel segment 12172 with different cross-sectional areas.

[0122] In some embodiments, the overlapping area between the orthographic projection of the first channel segment 12171 on the protective net 1252 and the orthographic projection of the second channel segment on the protective net 1252 has an overlapping area, and the orthographic projection of the first channel segment 12171 on the protective net 1252 has a projected area. The ratio between the aforementioned overlapping area and the aforementioned projected area can be between 0.4 and 0.6. If the aforementioned ratio is too small, the connection area between the first channel segment 12171 and the second channel segment 12172 may be too small, which is not conducive to sound entering the third microphone 1251 via the pickup channel 1217. If the aforementioned ratio is too large, the risk of the third microphone 1251 being directly impacted by external droplets or other contaminants increases.

[0123] In some embodiments, the first central axis and the second central axis can be arranged in parallel to make the wall thickness of the housing assembly 121 more uniform and avoid localized excessive thinness. In combination with... Figure 14 The first channel segment 12171 and the second channel segment 12172 partially overlap on the aforementioned first central axis. The size of the overlapping portion of the first channel segment 12171 and the second channel segment 12172 (e.g., |h1-h2|) is related to the depth of the first channel segment 12171 (e.g., ...). Figure 14 The depth of the middle h1) and the second channel segment 12172 (e.g. Figure 14 The ratio between the smaller of h1 and h2 can be between 0.5 and 0.8. If the ratio is too small, the connection area between the first channel segment 12171 and the second channel segment 12172 may be too small, hindering sound from entering the third microphone 1251 via the pickup channel 1217; if the ratio is too large, the housing assembly 121 may be locally too thin. It is understood that in some other embodiments, the first and second central axes may be angled, allowing adjustment of the length of the pickup channel 1217 while maintaining a fixed wall thickness of the housing assembly 121.

[0124] As an example, combined Figure 12 , Figure 15 and Figure 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 compartment body 1211 and an end cap 12121 that are interlocked in the first direction. The dimension of the housing assembly 121 in the second direction may be larger than the dimension 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 with a flat structure, which helps to reduce the dimension of the housing assembly 121 in the normal direction D5.

[0125] As an example, combined Figure 17 The housing 1211 has 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 can be smaller than the dimension of the second inner wall 12112 in the first direction, meaning that the depth of the housing 1211 in the first direction is not uniform but varies. A protective net 1252 can be fixed to the first inner wall 12111, and a third microphone 1251 is fixed to the protective net 1252. Thus, because the third microphone 1251, the protective net 1252, and other related structures are located at a shallower depth within the housing 1211, the assembly of the electronic device 10 is easier. Correspondingly, a pickup channel 1217 can be located on the side wall of the housing 1211.

[0126] Furthermore, a recessed area 12113 can be formed on the first inner wall 12111, and the pickup channel 1217 communicates with the bottom of the recessed area 12113. The protective mesh 1252 can be fixed to the bottom of the recessed area 12113 using double-sided tape or other adhesives. The third microphone 1251 can be at least partially located within the recessed area 12113 and can be fixed to the protective mesh 1252 using double-sided tape or other adhesives to increase the drop resistance of the third microphone 1251. Similarly, the third microphone 1251 can be mounted on the flexible circuit board 1253 using surface mount technology, and then connected to the circuit board 1221.

[0127] As an example, the first inner wall 12111 can be closer to the middle of the support component 12 than the second inner wall 12112, that is, further away from the mechanism module 11, and when worn, the sound pickup channel 1217 can be pointed to the back of the head, which helps to increase the anti-interference capability of the third microphone 1251.

[0128] It should be noted that the improvements to the pickup channel 1217 can also be applied to the pickup holes on the housing assembly 111 that cooperate with the first microphone 1161 and the second microphone 1162 respectively, which will not be elaborated here.

[0129] As an example, combined Figure 15 , Figure 17 and Figure 18 The electronic device 10 may include a button assembly 126 connected to the housing assembly 121. The button assembly 126 can be pressed in the direction of external force (e.g., ...). Figure 17Pressing the tactile switch 1227 on the circuit board 1221 (in the direction indicated by the middle arrow D8) expands the control functions of the electronic device 10, such as turning the electronic device 10 on / off, or increasing / decreasing the volume of the electronic device 10. The outer side of the housing assembly 121 may have a recessed area 1218, and the bottom of the recessed area 1218 has a button through-hole 1219. The button assembly 126 may be partially located within the recessed area 1218 and extend into the housing assembly 121 via the button through-hole 1219 to approach the tactile switch 1227.

[0130] In some embodiments, the number of button components 126 can be two, one of which is used to increase the volume of the electronic device 10, and the other is used to decrease the volume of the electronic device 10. For example, the two button components 126 are used to increase / decrease the volume of the electronic device 10, and one of the button components 126 is further reused to control the power on / off of the electronic device 10. In combination with... Figure 17 and Figure 18 The two button assemblies 126 can be respectively disposed in their respective recessed areas 1218, with the two recessed areas 1218 spaced apart, and each extending into the housing assembly 121 through its respective button through hole 1219, so that the two button assemblies 126 are independent of each other and do not interfere with each other. Correspondingly, the number of tactile switches 1227 can also be two, and they are respectively disposed one-to-one with the two button assemblies 126.

[0131] In some implementations, the number of button components 126 may be one, for example, for powering on / off the electronic device 10.

[0132] As an example, combined Figure 15 , Figure 17 and Figure 18 The button assembly 126 may include a button 1261 and a sealing ring 1262. The button 1261 may be partially located within the recessed area 1218 and extend into the housing assembly 121 through the button through-hole 1219, allowing the button assembly 126 to press the tactile switch 1227 in the pressing direction D8 under external force. The sealing ring 1262 may be located within the recessed area 1218 and surround the button through-hole 1219 to seal the button through-hole 1219. Furthermore, because the sealing ring 1262 has a certain amount of compression, it can also provide a certain amount of damping and rebound feel during user operation of the button 1261. Figure 17 The sealing ring 1262 shown is in its form before compression. After compression, it has a certain deformation to elastically support the button 1261 and the housing assembly 121. Of course, in some other embodiments, the side of the button 1261 facing the housing assembly 121 may be provided with a sealing groove for accommodating the sealing ring 1262.

[0133] As an example, combined Figure 17 , Figure 18 and Figure 22 The button 1261 may include an operation part 12611, a connector 12612 connected to the operation part 12611, and a latching part 12613 connected to the connector 12612. The operation part 12611 may be at least partially located in the recessed area 1218 and supported on the sealing ring 1262. The connector 12612 extends into the housing assembly 121 through the sealing ring 1262 and the button through hole 1219. The latching part 12613 engages with the inner side wall of the housing assembly 121, that is, the latching part 12613 is located on the inner side of the housing assembly 121 facing the circuit board 1221, so that the button 1261 is latched and fixed to the housing assembly 121. At this time, the sealing ring 1262 can have a 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 increasing 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-fit ​​fixation of the button 1261 and the housing assembly 121, the button 1261 may not include the snap-fit ​​part 12613. For example, an additional retaining member such as a retaining ring or pin independent of the button 1261 can be provided. After the aforementioned retaining member is assembled with the button 1261, it is located on the inner side of the housing assembly 121 facing the circuit board 1221.

[0134] As an example, combined Figure 17 and Figure 22 The connector 12612 can be cylindrical, and at least two slots 12614 extending axially along the connector 12612 can be provided at the end of the connector 12612 opposite to the operating part 12611, for example... Figure 22 As shown, the slot 12614 divides the connector 12612 along its axial direction into a first segment 12615 near the operating part 12611 and a second segment 12616 away from the operating part 12611. The first segment 12615 is continuously arranged circumferentially along the connector 12612, and a sealing ring 1262 is fitted onto the first segment 12615 to seal the key through hole 1219. The second segment 12616 has connector arms spaced apart circumferentially along the connector 12612. Figure 17 and Figure 22 (Not marked in the text) The number of latching parts 12613 is the same as the number of the aforementioned connecting arms and they are connected one by one.

[0135] Furthermore, a first guide surface can be provided on the side of the button through hole 1219 facing away from the circuit board 1221. Figure 17 and Figure 18 (Not marked in the text) The latching part 12613 may be provided with a second guide surface 12617. Thus, as the button 1261 extends into the housing assembly 121, the second guide surface 12617 and the aforementioned first guide surface cooperate with each other to bring the aforementioned connector arms closer together, thereby allowing the latching part 12613 to pass through the button through hole 1219.

[0136] As an example, combined Figure 17 The button assembly 126 may include a flexible adapter 1263 connected to the button 1261. The hardness of the flexible adapter 1263 is less than that of the button 1261. The button 1261 presses the tactile switch 1227 through the flexible adapter 1263, thereby providing a certain damping and rebound feel during user operation of the button 1261. The button 1261 may be made of polycarbonate or a mixture of at least one of glass fiber and carbon fiber, and the flexible adapter 1263 may be made of silicone, rubber, etc. Further, a portion of the flexible adapter 1263 may be inserted into the second post segment 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 through the flexible adapter 1263.

[0137] As an example, combined Figure 17 and Figure 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 in the pressing direction D8 than the second sub-recessed area 12182. The second sub-recessed area 12182 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-regions in the pressing direction D8, and the button through-hole 1219 is located 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 part 12611 may be at least partially located within the second sub-recessed area 12182. Thus, as the button 1261 moves relative to the housing 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 prevent the button 1261 from being over-pressed and the deformation of the sealing ring 1262 from being too large, thereby controlling the stroke of the button 1261 and extending the service life of the sealing ring 1262.

[0138] Furthermore, on a reference section parallel to the pressing direction D8, the sidewall of the first sub-recessed area 12181 can be at least partially arc-shaped, so that the bottom of the first sub-recessed area 12181 and its sidewall form an arc transition, thereby reducing (or even eliminating) the gap between the sealing ring 1262 and the housing assembly 121, and thus increasing the sealing effect of the sealing ring 1262 on the button through hole 1219.

[0139] As an example, combined Figures 15 to 18 and Figure 22 A first limiting structure 1271 can be provided within the recessed area 1218, located outside the sealing ring 1262. A second limiting structure 1272 can be provided on the operating part 12611. When the button assembly 126 is not pressed under external force, the first limiting structure 1271 and the second limiting structure 1272 can partially overlap in the pressing direction D8 and cooperate to limit the button 1261 in the circumferential direction of the button through hole 1219. This helps maintain the relative position of the button 1261 and the housing assembly 121 in the circumferential direction of the button through hole 1219, thereby preventing the gap between the operating part 12611 and the housing assembly 121 in the radial direction of the button through hole 1219 from being too small or too large. In addition, during the movement of button 1261 relative to housing assembly 121 along the pressing direction D8, the operating part 12611 can be stopped by the first limiting structure 1271, and / or the second limiting structure 1272 can abut against housing assembly 121 to prevent button 1261 from being over-pressed and the deformation of sealing ring 1262 from being too large, thereby controlling the stroke of button 1261 and extending the service life of sealing ring 1262.

[0140] As an example, combined Figures 15 to 18 and Figure 22The first limiting structure 1271 may include two first limiting blocks 12711 spaced apart circumferentially on the button 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, the groove 12721 causing a partial thinning of the operating part 12611. In the non-pressed state, the second limiting block 12722 is located between the two first limiting blocks 12711; in the pressed state of the button assembly 126 under external force, the second limiting block 12722 extends into the blind hole 12712, and the two first limiting blocks 12711 respectively extend into the groove 12721. In this way, not only can the button 1261 be limited in the circumferential direction of the button through hole 1219, but it also helps to reduce the size of the housing assembly 121 in the pressing direction D8 when the button assembly 126 has a preset stroke. Accordingly, the first limiting block 12711 can be located in 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 depth of the blind hole 12712 is large enough, thereby allowing the button assembly 126 to have sufficient stroke.

[0141] In some embodiments, the distance between the two first limiting blocks 12711 in the circumferential direction of the key through hole 1219 can be greater than the diameter of the blind hole 12712 in the circumferential direction of the key through hole 1219. The blind hole 12712 is provided with a guide arc surface or guide slope near the edge of the first limiting block 12711 so that the second limiting block 12722 can extend into the blind hole 12712.

[0142] In some embodiments, the distance between the two first limiting blocks 12711 in the circumferential direction of the key through hole 1219 can be equal to the diameter of the blind hole 12712 in the circumferential direction of the key through hole 1219, so that the second limiting block 12722 can extend into the blind hole 12712.

[0143] As an example, combined Figures 15 to 18 and Figure 22 The number of the first limiting structure 1271 and the second limiting structure 1272 can each be two, and the two first limiting structures 1271 and the two limiting structures 1272 are respectively arranged at a relative interval in the radial direction of the key through hole 1219. In this way, it is not only beneficial 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 beneficial to make the travel of the key 1261 more smoothly controlled.

[0144] As an example, combined Figure 15 , Figure 17 and Figure 18The recessed area 1218 and the button through-hole 1219 can be located at the bottom of the compartment 1211 opposite to the end cover 12121, so that structural components such as the button assembly 126 are fixed to the bottom of the compartment 1211, so that the user can operate the button assembly 126 while wearing the device. Of course, in some other embodiments, the relative positions between the bottom of the compartment 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 on the end cover 12121.

[0145] Based on the above description, the housing assembly 121 can serve as part of the support assembly 12 and can be used to house the circuit board 1221, battery, and other related structural components. In conjunction with...
