Bone conduction hair band hearing aid with Bluetooth and voice communication

Abstract

The invention discloses a bone conduction hair band hearing aid with Bluetooth and voice communication. The bone conduction hair band hearing aid includes a hair band body, a microphone head arranged on the hair band body, an audio amplifier circuit connected with the microphone head, a filter circuit connected with the audio amplifier circuit, and a bone conduction driving chip connected with the filter circuit and used for driving bone conduction vibrators, and also includes a Bluetooth module arranged on a circuit board, connected with the bone conduction driving chip and used for wirelessly receiving and transmitting data, and the bone conduction vibrators which are arranged on the hair band body and convert an amplified sound electric wave signal into a bone conduction vibration signal by driving of the bone conduction driving chip, wherein the bone conduction driving chip is connected with the bone conduction vibrators. According to the bone conduction hair band hearing aid with Bluetooth and voice communication, when a user wears the intelligent hair band, an acoustical signal can be utilized to vibrate a skull through a bone conduction method, and vibration directly enters a cerebral auditory nerve in a solid propagation mode, so that people with hearing impairment can have conversation with each other or communicate with normal people conveniently.

Description

technical field [0001] The invention relates to the field of smart wearable devices, in particular to a bone conduction headband hearing aid with Bluetooth and voice communication. Background technique [0002] Sound is produced by the vibration of objects, and the sounding object is called the sound source. Sound is just the movement of pressure waves through the air. Pressure waves vibrate the small bones in the inner ear (ossicles), and these vibrations are translated into tiny electrical brain waves, which we perceive as sound. The inner ear works on the same principle that a microphone's head captures sound waves or a loudspeaker makes sounds, it's the relationship between moving mechanical parts and air pressure waves. Naturally, when the sound waves are low-pitched, slow-moving, and loud enough, you can actually "feel" the air pressure waves vibrating your body. [0003] A hearing aid is a hearing aid, and it is also a small loudspeaker, which amplifies the origina...
