[0002] Speakers can be used in many occasions. For example, there is a relatively advanced bone conduction resonant Bluetooth speaker. Its resonant speaker is attached to other objects by means of sticking or suction cups, which produces resonance and amplifies the volume several times larger than the original volume, thereby achieving better acoustic effects. However, there are some problems with such speakers on the market. First, they are generally fixed by screws or ultrasonic welding, and the assembly process is complicated and difficult to disassemble, so they are not easy to disassemble and repair; second, the resonant speaker is only locked and fixed with the shell at its upper body, but the resonant part is not processed because it needs vibration space, which may cause it to be pulled off or even broken when it is lifted due to the strong adhesion of the sticking or the adsorption force of the suction cup.
