Background technology
The essence of sound is vibration, and the conduction of sound in health bone is divided into two kinds: have gas to conduct and osteoacusis.Time normal, the generation of the sense of hearing causes vibrophone by sound wave through external auditory meatus, then enter cochlea, and this is conventional gas conduction.
And sound is by skull, jawbone also can pass to auditory nerve, causes the sense of hearing, and scientific circles are called osteoacusis this conduction pattern of sound.Some people losing the sense of hearing can utilize osteoacusis to carry out hearing aid.It is said, after musician Beethovan deafness, the one end of the wooden stick that bites with the teeth exactly, the other end withstands on the sound of musical instrument that piano listens oneself to play, thus proceed creation.
Bone conduction speaker is a kind of osophone preferably, and its principle is exactly the conduction by bone, enables people hear sound by the vibration of loudspeaker and bone.Bone-conduction microphone then accepts to produce vibration signal at bone and sounding by vocal cords by the conduction of bone, and listener and user are talked with.
At present, bone conduction speaker and bone-conduction microphone are all comparatively develop into general ripe hearing aid technical products, on market some incorporated businesses also specialized designs be proposed the hearing aid product of the glasses being built-in with bone conduction speaker, but also not the hearing aid type glasses that bone conduction speaker and bone-conduction microphone gather together, user just can have the effect of hearing aid or sounding when wearing this glasses, and the osophone position of existing hearing aid type glasses is generally fixed, inconvenient different user regulates osophone position according to different use occasion, often user can not get suitable audio in specific environment.
In sum, market is badly in need of a kind of can set accepting sound and the subsidiary function of sounding and can the hearing aid type glasses of flexible, so that better assisted user exchanges with the external world is daily.
