HEARING AID SYSTEM USING WIRELESS OPTICAL COMMUNICATIONS
First Claim
Patent Images
1. A hearing aid system comprising:
- a voice transmitter that converts addresser'"'"'s voice into an optical signal to then transmit the converted optical signal; and
a hearing aid that restores the optical signal received from the voice transmitter into the addresser'"'"'s voice to then output the restored addresser'"'"'s voice,wherein the voice transmitter comprises;
a first microphone that converts the addresser'"'"'s voice into a first sound signal;
a second microphone converts the addresser'"'"'s voice into a second sound signal;
a voice transmitter signal processor that amplifies one of the first sound signal applied from the first microphone and the second sound signal applied from the second microphone;
a light emitter that converts the amplified sound signal applied from the voice transmitter signal processor into the optical signal to then transmit the converted optical signal; and
a voice transmitter switch that selects one of the first and second microphones, as a microphone that provides the sound signal to be amplified in the signal processor.

Abstract
Provided is a hearing aid system using a wireless optical communications method. The hearing aid system includes: a voice transmitter that converts addresser'"'"'s voice into an optical signal to then transmit the converted optical signal; and a hearing aid that restores the optical signal received from the voice transmitter into the addresser'"'"'s voice to then output the restored addresser'"'"'s voice. Accordingly, the addresser'"'"'s voice can directly be transmitted to the hard-of-hearing via wireless optical communications, to thereby prevent a voice discriminating power from lowering even in the case that ambient noise of an addresser as well as a listener is big.

10. A hearing aid comprising:
-
a light receptor that converts a received optical signal into a first sound signal to then output the converted sound signal; a hearing aid microphone that converts addresser'"'"'s voice into a second sound signal; a hearing aid signal processor that amplifies one of the first sound signal applied from the light receptor and the second sound signal applied from the hearing aid microphone; a speaker that converts the amplified sound signal applied from the hearing aid signal processor into the voice to then output the converted voice; and a hearing aid switch that selects one of the light receptor and the hearing aid microphone, as a microphone that provides the sound signal to be amplified in the hearing aid signal processor.
