The multifunctional device is suitable for the hearing-impaired. It consists of a casing, a telephone landline port on the periphery of the casing, a handle, a voice earmark interface, a hearing aid earphone interface, and a circuit. In the circuit, the input end of the function selection circuit is connected to the voice pickup The output end of the audio circuit and the telephone voice coupling circuit is electrically connected, the output end of the function selection circuit is electrically connected with the input end of the audio power amplifier circuit, and the port of the landline telephone is respectively connected with the input of the audio power amplifier circuit, the telephone voice coupling circuit, and the signal switching circuit The terminals are electrically connected, and the power supply circuit provides working power for each unit circuit; the handle, the earmark interface of the phone, and the hearing aid earphone interface are set at the output end of the audio power amplifier circuit. The invention integrates the functions of hearing aid, telephone sound amplification, and FM radio into one machine, fully meets the needs of hearing-impaired people and normal-hearing people in special occasions, and has the advantages of full functions, simple structure, convenient portability, and low cost of use.
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, telephone amplification and the like. Background technique [0002] In the prior art, products such as hearing aids, telephone loudspeakers, and FM radios suitable for the hearing-impaired bring convenience to the hearing-impaired, enabling them to live and work like normal hearing people. However, the above-mentioned products all exist as a single product in the known technology. If the hearing-impaired person wants to enjoy the functions of all the products, they must buy them one by one, which is not only expensive to use, but also inconvenient to carry and use. As for FM radio and TV listening, it can only be achieved through traditional hearing aids. If the external noise is too loud, it will affect the listening effect and make consumers very annoying. If a multi-function device ca...
