<P>PROBLEM TO BE SOLVED: To provide an easy to use hearing aid which has microphones fixed on left and right eyeglass frames apart from earphones and an amplification adjustor separated as a pocket type, and is easy for even the elderly to handle for themselves, capable of 3D reproduction (sound direction and distance perception) and free of howling, and which, with glasses on, can be used for a long time, thereby helping to solve the problem that for the elderly, hearing changes daily and everyday hearing aid adjustment is troublesome. <P>SOLUTION: Waterproofed and directional compact microphones (5) are fixed one each to near left and right eyeglass frame hinges (4). Signals from the microphones are input to amplification adjustors (10) of the hearing aid via conductors (6) in the eyeglass frames, receptacles (7), plugs (8) and lead wires (9), with microphone sensitivity VR (19), sound volume VR (17) and sound quality adjustment VR (18) arranged in place, allowing the elderly to manipulate easily. Amplification adjusted sound signals are guided from the frame conductors (6) into left and right ear holes for sound reproduction by earphones (14). Thus, as described above, an eyeglass type 3D hearing aid has the microphones, the hearing aid amplification adjustors, the earphones and the frame conductors all integrated as one body. <P>COPYRIGHT: (C)2012,JPO&INPIT |
