When the cover body 40 is snapped with the shell 10, each supporting rib 45 extends into the corresponding receiving groove 31 and abuts against the bottom wall of the corresponding receiving groove 31.

[0023] It should be pointed out that the provision of the support ribs 45 can improve the strength of the bracket 30, thereby providing a certain degree of protection for the bracket 30, reducing damage to the bracket 30 caused by vibration signals, and improving the stability of the bone conduction speaker.

[0024] Specifically, the bracket 30 may include an annular bottom 32, a first extension portion 33, a second extension portion 34 and a plurality of reinforcing ribs 35. The annular bottom 32 is connected to the driving mechanism 20 and defines a central hole 321.

[0025] The first extension portion 33 is arranged on the annular bottom 32 around the center hole 321 and extends in a direction away from the driving mechanism 20. The extension direction of the first extension portion 33 can be specifically perpendicular to the main surface (i.e., the surface with a larger area) of the annular bottom 32; a plurality of reinforcing ribs 35 are arranged on a side of the first extension portion 33 away from the center hole 321 and are spaced apart from each other along the circumference of the center hole 321. Specifically, each reinforcing rib 35 can extend in a direction away from the first extension portion 33, and the extension direction can be perpendicular to the extension direction at the corresponding position of the first extension portion 33; the second extension portion 34 extends from the annular bottom 32 in a direction away from the driving mechanism 20, and is connected to one end of the plurality of reinforcing ribs 35 away from the first extension portion 33.

[0027] Furthermore, the first extension portion 33 includes a first sub-extension portion 331 and a second sub-extension portion 332 that are arranged opposite to each other, and a first transition portion 333 and a second transition portion 334 connecting the first sub-extension portion 331 and the second sub-extension portion 332, wherein the first transition portion 333 is arranged at one end of the first sub-extension portion 331 and the second sub-extension portion 332, and the second transition portion 334 is arranged at the other end of the first sub-extension portion 331 and the second sub-extension portion 332.

[0028] It should be noted that the height of the first sub-extension portion 331 relative to the annular bottom 32 may be higher than the second sub-extension portion 332, wherein the height of the first transition portion 333 and the second transition portion 334 may be continuously transitioned between the first sub-extension portion 331 and the second sub-extension portion 332, so that the height of the first extension portion 33 relative to the annular bottom 32 changes continuously. Of course, the first transition portion 333 and the second transition portion 334 may also be configured so that the height of the first extension portion 33 relative to the annular bottom 32 changes in a stepped manner as a whole, which is not specifically limited here.

[0029] Furthermore, an annular step surface 13 is provided on the inner wall of the shell 10 of the bone conduction speaker near the opening 11, and the side of the annular bottom 32 of the bracket 30 that is away from the first extension portion 33 abuts on the annular step surface 13, and the cover body 40 abuts against the first sub-extension portion 331 and the second sub-extension portion 332, so that the normal direction of the contact surface between the cover body 40 and the human skin is inclined to the vibration direction of the driving mechanism 20, that is, the angle between the normal direction of the contact surface between the cover body 40 and the human skin and the vibration direction of the driving mechanism 20 is in the range of (0°, 90°).

[0030] The driving mechanism 20 may include a vibration transmitting plate disposed in the central hole 321 and connected to the bracket 30, a magnetic circuit assembly suspended on the vibration transmitting plate, and a coil disposed at the periphery of the central hole 321 and connected to the bracket 30.

When the cover body 40 is buckled with the shell body 10, each second receiving groove 312 and the corresponding first receiving groove 311 jointly receive the same corresponding first supporting rib 451, so that the first supporting rib 451 is respectively abutted against the bottom wall of the corresponding first receiving groove 311 and the second receiving groove 312, thereby playing a role in strengthening the bracket 30 and improving the stability of the bone conduction speaker.

[0035] Specifically, the plurality of first receiving grooves 311 are respectively disposed at intervals on the first sub-extension portion 331 or are disposed at intervals on the first sub-extension portion 331 , the first transition portion 333 , and the second transition portion 334 .

[0036] In an application scenario, the number of the first receiving groove 311, the second receiving groove 312 and the first supporting rib 451 are all four, wherein two first receiving grooves 311 are respectively arranged at intervals on the first sub-extension portion 331, one first receiving groove 311 is arranged on the first transition portion 333, and the other first receiving groove 311 is arranged on the second transition portion 334. Accordingly, the second extension portion 34 is only correspondingly arranged around the periphery of the first sub-extension portion 331, the first transition portion 333 close to the first sub-extension portion 331, and the second transition portion 334 close to the first sub-extension portion 331, and four second receiving grooves 312 corresponding to the four first receiving grooves 311 are arranged at intervals on the second extension portion 34. Furthermore, two reinforcing ribs 35 are respectively arranged at the connection between the first sub-extension portion 331 and the first transition portion 333, and at the connection between the first sub-extension portion 331 and the second transition portion 334, and the other two reinforcing ribs 35 are respectively arranged on the first transition portion 333 and the second transition portion 334.

[0037] Further, the second support ribs 452 can be arranged at intervals with the first support ribs 451 along the circumference of the center hole 321. Specifically, multiple first support ribs 451 and multiple second support ribs 452 can be arranged at intervals to cross each other, or multiple first support ribs 451 are arranged in a partial area of ​​the cover body 40, while multiple second support ribs 452 are arranged in another partial area of ​​the cover body 40 without crossing each other. The specific arrangement can be based on actual conditions and is not specifically limited here. Among them, when the cover body 40 is buckled with the shell 10, the multiple second support ribs 452 can all abut against the side of the annular bottom away from the driving mechanism 20, or cooperate with each other to abut against the side of the annular bottom facing the driving mechanism 20 and the side facing the cover body 40, thereby further stabilizing the bracket 30.
