Problems solved by technology

But above-mentioned product all exists with single product in known technology, if the hearing-impaired person wants to enjoy the function that all products have, just must buy individually one by one, not only use cost height, and carry, use also inconvenient, moreover, As for FM radio and TV listening, it can only be realized through traditional hearing aids. If the external noise is too loud, it will affect the listening effect and make consumers feel very troubled.

Description

technical field [0001] The invention relates to a device for the hearing-impaired, in particular to a multi-functional device for the hearing-impaired with hearing aid, listening, FM radio, and telephone amplification. Background technique [0002] In the prior art, products such as hearing aids, telephone loudspeakers, and FM radios suitable for the hearing-impaired have brought convenience to the hearing-impaired, enabling them to live and work like normal hearing people. But above-mentioned product all exists with single product in known technology, if the hearing-impaired person wants to enjoy the function that all products have, just must buy individually one by one, not only use cost height, and carry, use also inconvenient, moreover, As for FM radio and TV listening, it can only be realized through traditional hearing aids. If the external noise is too loud, it will affect the listening effect and make consumers feel very troubled. If a ki...
