A bone conduction headband

Abstract

The invention relates to a bone conduction hair clasp. The bone conduction hair clasp comprises flexible and ductile horseshoe-shaped hair clasp body, a sound absorption cotton layer, a fabric wrapping layer, a decorating layer, at least two bone conduction oscillators, at least two sound leak prevention buffers, at least two sponge covers, at least one air conduction microphone, at least one bone conduction microphone, a circuit mainboard, a rechargeable battery and a one-to-multiple sound frequency power divider. The one-to-multiple sound frequency power divider is connected with the circuit mainboard on the outer side of the hair clasp body and the bone conduction oscillators on the inner side of the hair clasp body, and the bone conduction oscillators are connected with a port of a bone conduction oscillator driver on the circuit mainboard through the one-to-multiple sound frequency power divider. The bone conduction hair clasp achieves functional diversification, can be implemented in a wireless connection or wired connection mode, solves the problems of sound leak and ambient noise interference, achieves high-quality bone conduction sound frequency, simplifies circuit design, lowers cost and energy consumption, has the intelligent personal assistant function and achieves friendlier interaction with a user.

Description

technical field [0001] The invention relates to a bone conduction headband, which belongs to the technical field of intelligent hardware wearable devices. Background technique [0002] In the prior art, people usually use headbands to fix their hair and maintain their hairstyles. In addition, traditional headbands also have the function of decoration and beauty. However, this traditional headband has a single function and does not have intelligent functions such as listening to music, answering calls, and personal voice assistants. [0003] In order to enable the headband to have intelligent functions such as voice interaction, it is necessary to introduce sound conduction technology. Normally, most of the sound we hear is carried by sound waves through the air. Air-conducted sound waves pass through the outer ear and middle ear to the cochlea and inner ear where they are perceived by the auditory nerve. In addition, sound waves can also be converted into mechanical vibra...

AI Technical Summary

Problems solved by technology

[0010] 2. Bone and human tissue will produce frequency-selective amplitude attenuation and delay of the vibration signal, and it is difficult for high-fidelity or broadband audio signals to be transmitted to the auditory nerve through the bone

[0012] 4. Because of the characteristics of solid conduction vibration, none of the existing technologies can really solve the problem of bone conduction sound leakage

This is because the existing technology uses large volume and large vibration signals to compensate the frequency-related human bone and tissue attenuation vibration signals, but this method will cause serious sound leakage, or require more power, bone conduction vibrator The volume and weight are greatly increased, making the overall equipment too heavy
