Description

Multifunctional bone conduction hearing aid
Technical Field
The invention relates to the technical field of wearable intelligent equipment, in particular to a multifunctional bone conduction hearing aid.
Background
Sound is generated by the vibration of an object, and the object that is producing sound is called a sound source. Sound is simply the movement of pressure waves through air. The pressure wave vibrates the small bones of the inner ear (auditory ossicles), and these vibrations are converted into tiny electronic brain waves, which are the sounds we perceive. The inner ear uses the same principle as a microphone head capturing sound waves or the sound of a loudspeaker, which is the relationship between the moving mechanical parts and the pressure waves. Naturally, when the sound wave tone is low, moving slowly and large enough, the pressure wave can actually be "felt" to vibrate the body.
The hearing aid is an auxiliary hearing tool and is also a small loudspeaker, original inaudible sound is amplified, and residual hearing of the hearing-impaired people is utilized, so that the sound can be transmitted to the auditory center of the brain, and the user feels the sound. Hearing aids are classified into air conduction hearing aids and bone conduction hearing aids in terms of conduction.
Under normal conditions, we listen to sound in at least two ways: bone conduction and air conduction. The bone conduction mode is that sound signals vibrate the skull and are directly transmitted to the inner ear without passing through the outer ear and the middle ear; the air conduction mode refers to the transmission of sound through the outer ear and the middle ear to the inner ear.
Along with the development of science and technology and the continuous improvement of people's standard of living, the use of various intelligent wearing equipment is more and more popularized.
