Abstract
The invention relates to a bone conduction loudspeaker. The bone conduction loudspeaker comprises a shell; wherein a magnetic circuit module is arranged in the shell, and a voice coil is arranged in the magnetic circuit module; the magnetic circuit module is provided with a vibration module; the vibration module is used for being matched with the magnetic circuit module to achieve the purpose of vibration; the vibration module is provided with a vibration transmission part for transmitting sound; the vibration transmission part is a PCB, wherein a connecting contact is welded on the PCB, and the connecting contact provides conditions for electric connection of the voice coil and an external controller, so that the external controller drives the voice coil to work through the PCB. The bone conduction loudspeaker has the effects of being convenient to supply power to the voice coil and simple and easy to operate.
Description
technical field [0001] The present application relates to the technical field of sound propagation, in particular to a bone conduction speaker. Background technique [0002] Bone conduction is a way of sound conduction, that is, by converting sound into mechanical vibrations of different frequencies, sound waves are transmitted through the human skull, bone labyrinth, inner ear lymph fluid transmission, screw, auditory nerve, and auditory center. Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction saves many steps of sound wave transmission, and can achieve clear sound reproduction in noisy environments, and the sound waves will not be affected by the diffusion in the air. others. [0003] Existing bone conduction speakers include a magnetic circuit module, a vibration module, and a vibration transmission piece. When the magnetic circuit module is working, it can drive the vibration module to vibrate, indirectly...
