Abstract

PROBLEM TO BE SOLVED: To provide a hearing aid effective for a person having severe conduction hearing loss by adhering and fixing a earphone part, in which sounds collected by a sound-collecting microphone is amplified to a sound-collecting part. SOLUTION: This sound-collecting microphone 4 is connected with one of an amplifier 3 with a built-in battery, a power switch, a volume adjusting function, etc., with a cord and the earphone part 2 is similarly connected with the other by a cord. A projecting part 8 of the earphone part 2 is inserted into a recessed part 7 of a hearing aid main body 1, fixed there so as to be adhered to the sound collecting part of the hearing aid main body 1, the sound collected by the sound collecting microphone 4 is amplified by the amplifier 3 and transmitted via the sound collecting part 6 formed by adhering the earphone part 2 to the hearing aid main body 1 with an insertion type earphone part 2 in telephone mode. Thus, normal sounds which are difficult to be heard by the hearing aid 1 is made to be heard clearly in a telephone mode by the person having severe conduction hearing loss. In addition, the sound collecting microphone 4 and the earphone part 2 are also fetched in the amplifier 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a hearing aid which is effective for a person with severe conductive hearing loss.
A conventional hearing aid is composed of a sound collecting unit, an amplifying unit, an earphone unit, a battery, and the like, and has a mode changeover switch that can select a normal state or a telephone state according to a purpose of use. A person with severe conductive hearing loss could hear phone calls in the telephone mode, but it was difficult to hear normal voices in the normal mode. According to the present invention, ordinary voice can be clearly heard. This will be described with reference to the drawings. A sound collecting microphone 4 is connected to one end of an amplifier 3 having a battery, a power switch, a volume control function, and the like by a cord, and the earphone unit 2 is connected to the other end by a cord. The projection 8 of the earphone 2 is fitted into the recess 7 of the conventional hearing aid main body 1 so as to be in close contact with the sound collecting section 6 of the conventional hearing aid main body 1 having the earplug 5 in the telephone mode.
And fix it. The present invention provides the sound collecting microphone 4 as described above.
The sound coming in from is amplified by the amplifier 3 and the
Through the sound collecting unit 6 of the hearing aid body 1 having the conventional structure. As a result, a person with severely conductive hearing loss can clearly hear ordinary voice in the telephone mode, which is difficult to hear with a conventional hearing aid. Note that the sound collecting microphone 4 and the earphone unit 2 can be incorporated in the amplifier 2. Further, the earphone unit 2 can be integrated into the hearing aid body 1 having a conventional structure.
