Headband bone conduction hearing aid with voice communication

Abstract

The invention discloses a headband bone conduction hearing aid with voice communication. The headband bone conduction hearing aid comprises a headband body, a microphone, an audio amplifier circuit, a filter circuit, a bone conduction driving chip and a bone conduction vibrator, wherein the microphone is arranged on the headband body; the audio amplifier circuit is connected with the microphone; the filter circuit is connected with the audio amplifier circuit, and used for filtering clutter generated in the circuit; the bone conduction driving chip is connected with the filter circuit, and used for driving the bone conduction vibrator; the bone conduction vibrator is arranged on the headband body, and driven by the bone conduction driving chip to convert an amplified sound electrical wave signal into a bone conduction vibration signal; and the bone conduction driving chip is connected with the bone conduction vibrator. Through adoption of the headband bone conduction hearing aid, sound signals are transmitted into a skull in a vibrating way, and vibration directly enters brain auditory nerves in a solid transmission way after a user wears an intelligent headband, so that a person with a hearing impairment can have a dialogue with other persons with hearing impairments or communicate with able-bodied persons.

Description

Technical field [0001] The invention relates to the field of smart wearable devices, and in particular to a headband bone conduction hearing aid with voice communication. Background technique [0002] Sound is produced by the vibration of an object, and the object that is making a sound is called the sound source. Sound is just the movement of pressure waves through the air. Pressure waves vibrate the small bones of the inner ear (ossicles). These vibrations are converted into tiny electronic brain waves, which are the sounds we perceive. The principle used by the inner ear is the same as that of the microphone head capturing sound waves or the sound of the speaker. It is the relationship between the moving mechanical part and the pressure wave. Naturally, when the sound wave is turned down, moving slowly and large enough, you can actually "feel" the pressure wave vibrating the body. [0003] Hearing aid is a kind of auxiliary hearing tool and a small loudspeaker, which amplifie...
