Wherein, the fixing mechanism 210 acts on the bone conduction speaker 100 so as to attach the bone conduction speaker 100 to the back of the auricle of the user at least when the bone conduction speaker 100 is in the use state. It is understood that in various embodiments, bone conduction speaker 100 may be at least one of an electromagnetic speaker, a piezoelectric speaker, and an electrostatic speaker. Specifically, the electromagnetic speaker may be a moving coil speaker, a moving iron speaker, or the like.

In the present embodiment, bone conduction speaker 100 is attached to the back surface of the auricle of the user, and bone conduction sound and vibration can be transmitted by the cartilage of the auricle.
Referring to fig. 2 to 4, fig. 3 is a schematic exploded view of an embodiment of bone conduction speaker 100. Fig. 4 is a schematic cross-sectional view of an angle of an embodiment of bone conduction speaker 100. The bone conduction speaker 100 provided by the application comprises a shell 10, a transduction assembly 20 arranged in the shell 10, and a vibration transmission assembly 30 connected with the transduction assembly 20.
Specifically, the housing 10 is used to house and fix the transducer assembly 20 and the vibration transmission assembly 30, and serves as a casing of the bone conduction speaker 100. Specifically, the housing 10 includes a body 12 and a base 14, the body 12 is wrapped around the periphery of the transducer assembly 20, and the body 12 is clamped with the base 14, or the body 12 and the base 14 are integrally formed. It will be appreciated that the housing 10 serves to carry and protect the transducer assembly 20 as well as the vibration transfer assembly 30.
The transducer assembly 20 is disposed in the housing 10, and is configured to generate vibrations when excited by an electrical signal, and to transmit the vibrations to the vibration transmitting assembly 30. In one implementation, the transducer assembly 20 is fixedly connected to the vibration transmitting assembly via the connection 40. Specifically, transduction assembly 20 includes magnetic circuit 22, voice coil 24, and armature 26 coupled to voice coil 24. Specifically, the voice coil 24 is disposed in a magnetic gap formed by the magnetic circuit 22, and the voice coil 24 is connected with the bracket 26; a vibration transfer assembly 30 is coupled to the bracket 26 to transfer vibrations from the bracket 26.
The vibration transfer assembly 30 is used to transfer vibrations generated by the transducer assembly 20 to the skin being applied. Specifically, in one embodiment, the vibration-transmitting assembly 30 includes a vibration-transmitting member 32 coupled to the transducer assembly 20 and an engaging member 34 disposed on the vibration-transmitting member 32 for engaging the skin. The abutment 34 is in contact with the back of the pinna and vibrations generated by the transducer assembly 20 are transmitted to the pinna through the vibration transmitting member 32 and the abutment 34. Specifically, in the present application, the attaching member 34 includes a central attaching portion 342 fixedly connected to the vibration transmitting member 32, and a peripheral attaching portion 344 surrounding the periphery of the central attaching portion and connected to the outer edge of the central attaching portion 342, for attaching to the back of the auricle of the user when the bone conduction speaker 100 is in the use state. Wherein, the center attaching portion 342 and the peripheral attaching portion 344 attach to the skin together, i.e. attach to the back of the auricle of the user together, so as to increase the attaching area of the bone conduction speaker 100 and the back of the auricle of the user, and further realize that the sound/vibration passes through the back of the auricle, so that the sound heard by the user is louder.
It will be appreciated that, where the fitting member 34 is soft rubber, the vibration-transmitting member 32 is also made of plastic, but the rigidity of the vibration-transmitting member 32 is greater than that of the fitting member 34. The abutment member 34 is adapted to be applied to the back of the pinna of the user to undergo minute deformations.
Optionally, in an embodiment, the central attaching portion 342 is at least partially a flat plane, and the peripheral attaching portion 344 is disposed around the periphery of the central attaching portion 342 and is an arc surface with a relatively small arc. Specifically, the peripheral attaching portion 342 can elastically bend toward the housing 10 relative to the central attaching portion 342 under the pressure of the skin, so that the attaching member 34 has a larger area to attach to the back of the auricle of the user, so that the attaching member 34 can be in further sufficient contact with the back of the auricle of the user, and the efficiency of sound/vibration transmission of the attaching member 34 through the back of the auricle of the user is improved.
Referring to fig. 3 and 4, in particular, in one embodiment, the outer end surface of the vibration transmitting member 32 and the inner end surface of the central attaching portion 342 are attached to each other, so that the vibration generated by the transducer assembly 20 can be better transmitted to the attaching member 34 through the vibration transmitting member 32. Further, specifically, the outer end surface of the vibration transmitting member 32 is an arc surface protruding toward the center attaching portion 342, and the thickness of the center attaching portion 342 is gradually reduced in a direction toward the center line of the outer end surface of the vibration transmitting member 32, so that the outer end surface of the center attaching portion 342 is flatter than the outer end surface of the vibration transmitting member 32, so as to be better in contact with the back surface of the auricle of the user. Further optionally, in an embodiment, the outer end surface of the vibration transmitting member 32 includes a top surface 322 and an arc surface 324 surrounding the top surface, and correspondingly, the inner end surface of the central attaching portion 342 includes a first attaching portion 3422 attached to the top surface of the vibration transmitting member 32, and a second bonding portion 3424 attached to the arc surface 324 of the vibration transmitting member 32. By adopting the structure, the bonding area of the vibration transmission piece 32 and the central bonding part 342 is increased, the whole outer end surface of the vibration transmission piece 32 is surrounded by the inner end surface of the central bonding part 342, and the vibration transmission effect is better.
Optionally, in an embodiment, the thickness of the central conforming portion 342 is greater than the thickness of the peripheral conforming portion 344. It will be appreciated that the central attachment portion 342 is a central portion of the bone conduction speaker 100 attached to the back of the auricle of the user, and when the attachment member 34 contacts the back of the auricle of the user, the central attachment portion 342 and the peripheral attachment portion 344 are correspondingly deformed in cooperation with the back of the auricle of the user, and the center of the central attachment portion 342 is generally taken as the main stress point. Therefore, with the above structure, the center attaching portion 342 transmits the force to the peripheral attaching portion 344 better while the center attaching portion 342 is slightly deformed in the process of deformation, so that the peripheral attaching portion 344 deforms correspondingly, the attaching area of the whole attaching portion 34 and the back of the auricle of the user is increased, and a good attaching feeling is formed.
Optionally, in an embodiment, the width of peripheral bond 3424 of bonding element 34 is greater than the thickness of peripheral bond 344. To ensure that peripheral abutment 344 has the proper thickness and width that is as large as possible, thereby increasing the area of the entire abutment 34 that can be engaged against the back of the pinna.
Optionally, in an embodiment, the abutment 34 further comprises a cylindrical extension 346 connected with the outer edge of the peripheral abutment 344 and extending towards the housing. The cylindrical extension 346 serves to secure the entire fitting 34 to the housing 10. Further, in an embodiment, the housing 10 is further provided with a receiving groove 16, and an end of the cylindrical extension 346 remote from the peripheral fitting 344 is inserted into the receiving groove 16 to perform a fixing function. Alternatively, the cylindrical extension 346 and the receiving groove 16 may be engaged with each other by a snap fit or an interference fit, or the bone conduction speaker 100 of the present application further includes a sealant 50 filled in the receiving groove 16, and the sealing connection between the cylindrical extension 346 and the housing 10 is achieved by the sealant 50, so as to perform a good fixing function. Other fixation forms may be used in other embodiments, which are not particularly limited.
Alternatively, in one embodiment, the outer circumferential surface of the cylindrical extension 346 is provided with an annular groove 3462, wherein the wall thickness of the cylindrical extension 346 in the annular groove 3462 is smaller than the wall thickness of the cylindrical extension 346 in other areas outside the annular groove 3462. By adopting the structure, the part of the peripheral attaching part 344 above the annular groove 3462 can take the space formed by the annular groove 3462 as a deformation space when being stressed, and corresponding deformation is generated to better attach to the back of the auricle of the user.
Optionally, in an implementation, the peripheral attachment portion 344 is provided with a plurality of sound guiding holes 3444, and the plurality of sound guiding holes 3444 are disposed around the central attachment portion 342. With the above structure, the sound guiding hole 3444 can effectively reduce the area of the non-bonded region of the bonding member 34 and the vibration transmission member 32, so that the air inside and outside the bonding member 34 is transparent, and the pressure difference between the air inside and outside is reduced. On the other hand, the sound guiding hole 3444 may guide the sound wave formed by the air vibration inside the bonding element 34 to the outside of the bonding element 34, so as to cancel the sound leakage wave formed by the air outside the bonding element 34 driven by the vibration of the bonding element 34, so as to reduce the amplitude of the sound leakage wave. Optionally, in an embodiment, a plurality of sound guiding holes 3444 are spaced around the central conforming portion 342. In another embodiment, the plurality of sound guiding apertures 3444 are uniformly disposed about the central conforming portion 342.
Alternatively, in one embodiment, the abutment 34 is integrally formed from plastic. It will be appreciated that when the abutment 34 comprises multiple parts, the multiple parts are integrally formed of plastic, such as the central abutment 342 and the peripheral abutment 344 being integrally formed of plastic. As another example, in embodiments where the abutment 34 includes a central abutment 342, a peripheral abutment 344, and a barrel extension 346, the central abutment 342, the peripheral abutment 344, and the barrel extension 346 are integrally formed from plastic. In other embodiments, the components of the attaching member 34 may be fixed by other splicing methods, and are not necessarily limited to being integrally formed by plastic.
The foregoing description is only of embodiments of the present application, and is not intended to limit the scope of the application, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present application or directly or indirectly applied to other related technical fields are included in the scope of the present application.
