Osteoacusis multi-sound channel device

Abstract

A multisound-channel device of bone conduction is prepared as using multisound-path oscillator or delay module to make stereo sound-channel effect, enabling to place said device at any position of human head to let said device contact closely with bone skin for transmitting acoustic wave signal to human ear from different orientations separately to form stereo function with multi-sound channel or convert voice to be voice signal by utilizing bone conduction principle through bone skin at different positions.

Description

technical field [0001] The invention relates to a bone conduction multi-channel device, in particular to a bone conduction multi-channel device which produces a stereo channel effect through a multi-channel oscillator or a delay module. [0002] The device is placed on any part of the skull, so that the bone conduction output device and bone conduction input device carried by it are in close contact with the bone skin, so as to use the bone conduction principle to transmit the sound wave signal through the contact of different parts of the bone skin, It is transmitted to the ear from different directions to form a multi-channel stereo sound collection function; the sound to be transmitted can also be converted into a sound signal through bone conduction. Background technique [0003] Sound is conducted through the air, but wireless earphones or hearing aids that generally guide sound into the ear through the air often cannot eliminate external background sound sources, so os...

Problems solved by technology

However, the configuration attached to any position on the face does not necessarily have the effect of bone conduction

[0005] Another existing general contact indirect sound wave bone conduction device placed on the neck can eliminate part of the background sound, but because it is in contact with the throat, the sound quality transmitted is cloudy and unclear, and it is clamped on the neck at the same time. The part is easy to slide, which is very inconvenient and unsightly, and the audio signal of the existing general contact indirect bone conduction device placed on the neck is relatively attenuated and unclear compared to the audio signal in ordinary local calls

[0006] Another existing bone conduction glasses-type hearing aid places the oscillator at the end of the ear of the glasses frame to receive the sound. Although it can eliminate the background sound, it can only solve the problem of hearing and cannot produce sound. The tripod of the glasses will be loose and cannot fit the ear bone, which will greatly reduce the effect of hearing aids; in recent years, mobile devices such as mobile phones have become popular and frequently used, and wireless Bluetooth hands-free communication devices have become popular, which solves the problem of using mobile devices. Hearing and speaking problems, however, the external background noise cannot be avoided, the clip-on ear style is uncomfortable to wear for a long time, the heavy glasses tripod is not very beautiful, and the hearing aid is prone to sweating behind the ear, which will cause the hearing aid to lose its function, and it is easy to fall off during exercise. As its disadvantage, at the same time, if this type of bone conduction glasses-type hearing aid needs to use the left and right glasses legs, it cannot share components such as batteries, microphones, etc. economic benefits
