Earphone with hearing-aid function

Abstract

The invention relates to an earphone with an otacoustic function, which comprises a main body provided with a digital signal processor (DSP), and at least one earplug body provided with an external microphone and a loudspeaker, wherein the external microphone and the loudspeaker are electrically connected with the digital signal processor; and sound waves from the outside world can be converted into electronic signals through the external microphone, the electronic signals are then transmitted to the digital signal processor for further processing, and finally the processed electronic signals are converted into the sound waves by the loudspeaker.

Description

technical field [0001] The present invention relates to earphones, in particular to an earphone with a hearing aid function, which uses a digital signal processor to process electronic signals converted from external sound waves, and has the feature of improving the sound quality of hearing aids. Background technique [0002] The basic principle of existing hearing aids is to receive external sound through a microphone, and then amplify the sound signal through an amplifier; the amplified sound is output through a combination of an earphone (earphone) and an eardrum (ear-mold). to the eardrum to achieve the effect of hearing aid. Among them, the amplifier can provide hearing-impaired people to adjust the volume. [0003] However, for the hearing-impaired, the purpose of using a hearing aid is to amplify the conversation sound, and the frequency spectrum of certain noises in the environment and the spectrum of the conversation sound are repeated; in other words, the existing...

Problems solved by technology

[0003] However, for the hearing-impaired, the purpose of using a hearing aid is to amplify the conversation sound, and the frequency spectrum of certain noises in the environment and the spectrum of the conversation sound are repeated; in other words, the existing hearing aids also amplify the conversation sound Amplifies the noise in the environment, making it difficult for the hearing-impaired to identify the content of the conversation; at the same time, the hearing-impaired is also more likely to be disturbed by noise when listening to the conversation, which may cause auditory discomfort

[0004] In addition, the existing hearing aids have a certain volume in design, and in order to consider the effect of hearing aids, the hearing aids must partially extend into the ear canal of the human body and occupy part of the ear canal space to achieve the purpose of hearing aids; however, there are The eardrum of the hearing aid is designed to completely cover the ear canal; when the hearing-impaired wears the hearing aid, it will no longer be able to be used with the earphone, which has the disadvantage of being inconvenient to use

[0005] To sum up, due to the limitations of hearing aids, the hearing-impaired cannot use earphones, and the existing hearing aids cannot filter out external noise and cannot provide better sound quality, so the shortcomings of poor hearing aid effect need to be improved.
