Abstract

The invention provides a bone conduction earphone based on a digital equalization technology, which comprises a bone conduction earphone module and an ear hook, and is characterized in that the bone conduction earphone module comprises a wireless communication unit, a digital equalization processing unit, a voice enhancement processing unit, a controllable switch, an audio processing chip and a bone conduction unit, wherein the wireless communication unit, the digital equalization processing unit and the controllable switch are connected in sequence, the output end of the controllable switch is connected with the audio processing chip and the voice enhancement processing unit, and the audio processing chip is connected with the bone conduction unit. The performance of the bone conduction earphone is improved by adopting a digital equalization technology, and the voice enhancement processing unit is arranged, so that noise interference can be further reduced.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a bone conduction earphone based on digital equalization technology. Background technique [0002] Bone conduction earphones are different from traditional air conduction earphones. They convert sound into mechanical vibrations of different frequencies, and transmit sound waves through the human skull, bone labyrinth, inner ear lymph fluid transmission, spiralizer, auditory nerve, and auditory center. Compared with the classic air conduction earphones that generate sound waves through the diaphragm, bone conduction earphones simplifies the steps of sound wave transmission, can achieve clear sound reproduction in noisy environments, and the sound waves will not spread and affect others, and can also improve The confidentiality of sound transmission, such as helicopters, submarines, mines, traffic police, firefighting, etc. Bone conduction earphones can be used not on...
