Description

Bone conduction loudspeaker

Technical Field

The utility model relates to a bone conduction speaker technical field especially relates to a bone conduction speaker.

Background

Usually sound is transmitted by air conduction, and the vibration of the sound is transmitted to the eardrum in the ear. There are three ossicles in the ear, and sound is transmitted through the ossicles to the cochlea by the vibration of the periosteum. The cochlea is filled with lymph fluid, and the vibration of the lymph fluid reaches the auditory nerve in the process of being converted into an electric signal. The human brain can recognize the voice in the above manner. The so-called bone conduction is a mechanism for recognizing sound, which omits the process that vibration needs to pass through the periosteum and the ear ossicles, and directly transmits the vibration of sound to the cochlea through the skull. Therefore, even if the periosteum and the ossicles of the ear are abnormally low in hearing, the sound can be clearly heard by using the bone conduction method when the cochlea or the auditory nerve is still normal. The speaker using this principle is a bone conduction speaker. All can be provided with the china department piece in a lot of bone conduction speakers at present, realize magnetic conduction and fixed magnet's effect through the china department piece, but in less volume, the certain speaker of volume, because the existence of china department piece, the volume of magnet will be done comparatively less, can make the well high tone quality of speaker not high like this, and the bass performance of general bone conduction speaker is also not too good moreover, needs to improve the tone quality of bone conduction speaker through certain structure.
