Wireless earphone with hearing-aid function

Abstract

The invention relates to a wireless earphone with an otacoustic function, which comprises a main frame and two ear hanging pieces. The earphone also comprises a digital signal processor, a servo end wireless transmitting module and a servo end wireless receiving module, wherein the digital signal processor is electrically connected with the servo end wireless transmitting module and the servo end wireless receiving module; the two ear hanging pieces comprise a microphone, a loudspeaker, a guest end wireless transmitting module and a guest end wireless receiving module respectively, the guest end wireless transmitting module is electrically connected with the microphone and the guest end wireless receiving module is electrically connected with the loudspeaker; and the microphone can receive sound waves from the outside world and change the sound waves into electronic signals which are then transmitted to the digital signal processor through the guest end wireless transmitting module and the servo end wireless receiving module, and then the processed electronic signals are transmitted to the loudspeaker to be converted into the sound waves through the servo end wireless transmitting module and the guest end wireless receiving module.

Description

technical field [0001] The invention relates to earphones, in particular to a wireless earphone with hearing aid function and the feature of improving hearing aid effect. Background technique [0002] The basic principle of existing hearing aids is to receive external sounds through a microphone, and then amplify the sound signal through an amplifier, which can provide hearing-impaired people with the ability to adjust the volume; The combination of ear-molds outputs sound, which is then transmitted to the eardrum to achieve the effect of hearing aid. [0003] However, for the hearing-impaired, the purpose of using a hearing aid is to amplify the talking sound, while the frequency spectrum of certain noises in the environment and the frequency spectrum of the talking sound are repeated. In other words, while the existing hearing aids amplify the conversation sound, they also amplify the noise in the environment, making it difficult for the hearing-impaired to identify the c...

However, when people recognize the direction of the sound, they judge by the sound changes felt by the two ears at different listening positions; The sound receiving position of the main unit is different from the position of the human ear where the earmolds are located, which may cause the hearing-impaired to misjudge the sound position, and has the disadvantage of poor hearing aid effect

In addition, when the position of the receiving host calculates the relative distance with respect to the left and right ears, if the position of the
