Face bone conduction sound-conducting device with buffering mechanism

Abstract

The invention discloses a face bone bone conduction sound conducting device provided with a cushioning device, which is characterized in that: the cushioning device is added and arranged between a vibrating element and skin to cause vibration force of the vibrating element not to directly strike on the skin, and to disperse the vibration force on the cushioning device as equal as possible, so as to avoid the situation of itching of the skin caused by that the vibrating element directly strikes on the skin, thus increasing the comfort level of the face bone bone conduction sound conducting and being used for a long time.

Description

technical field [0001] The invention relates to an improvement of a facial bone bone conduction sound transmission device, in particular to a facial bone bone conduction sound transmission device with a buffer device between a vibrating element and the skin. Background technique [0002] To hear sound, in addition to sensing the sound vibration of the outside air through the eardrum of the inner ear (called air conduction sound transmission), another way is to use the knocking of the skull to transmit the sound to the auditory nerve through the bone and enter the brain (called air conduction sound transmission). Bone conduction is a type of hearing aid). Among them, the biggest problem of bone conduction sound transmission is that it knocks on the bone, and the skull is covered by muscles and skin. If you beat the skin hard for a long time, it will cause skin itching and allergies, which is a common problem. [0003] Take the earbone sound aid as an example, it uses electro...

AI Technical Summary

Problems solved by technology

Therefore, both the piezoelectric vibrator and the electromagnetic vibrator have the same problem, that is, the vibration distribution is uneven, and there is an area of ​​maximum amplitude, which causes the skin to itch easily.
