Description

[Detailed explanation of the idea] This invention relates to improvements in telephone hearing aid devices.

When a hearing-impaired person uses a hearing aid to make a telephone call, there is a means to receive the sound magnetic flux generated from the telephone receiver with a telephone pick-up coil built into the hearing aid, amplify it, convert it into an audio signal, and listen to it. , widely used.

On the other hand, as a countermeasure in cases where the audio magnetic flux leaking from the telephone handset is weak and difficult to hear, the audio signal emitted from the telephone handset is received by a microphone, amplified, and a sound current is passed through a separate loop. It is also known to pick up the audio magnetic flux with a telephone pick-up coil of a hearing aid. In this case, in actual use, there is a problem in coupling the telephone handset and the microphone, and it has been awaited to realize a configuration that can be used while maintaining a fixed relative position.

This invention responds to the above-mentioned requirement when the leakage magnetic flux from a telephone handset is weak, and aims to provide a telephone hearing aid device that is simple in structure and convenient to use.

Hereinafter, this invention will be explained using the embodiments shown in the drawings. In FIG. 1, a shell-shaped adapter 2 of a shape and size that can be fitted into the handset 1A of the handset 1 of a telephone set is molded from synthetic resin. adapter 2
Attach a small microphone 3 and a switch 4 to the The output of the microphone 3 is led out by a conductor 5 and applied to an amplifier 6, and the amplified audio current is passed from a conductor 7 to a suitable loop 8. The adapter 2 is appropriately provided with a sound emitting hole 2A.

When using the above configuration, by fitting the adapter 2 to the handset 1A and closing the switch 4, the sound emitted from the handset 1A is received by the microphone 3, amplified by the amplifier 6, and sufficiently transmitted from the loop 8. Since it is generated as a large sound magnetic flux, by placing the hearing aid 9 near the loop 8,
The sound is detected by a telephone pickup coil provided in the hearing aid 9 and listened to by the earphone 9A. That is, since the adapter 2 holding the microphone 3 is fitted onto the receiver 1A, there is no inconvenience when using it, and furthermore, the adapter 2 is provided with the sound emitting hole 2A. , with adapter 2 attached,
It does not interfere with normal telephone use by people with normal hearing. Furthermore, the telephone itself does not require any processing.

Although the above embodiment has a configuration in which the amplifier and loop are led out from the adapter, it is also possible to have a configuration in which the amplifier, loop, etc. are all attached to the adapter, and this example is shown in FIG. This will be explained with reference to FIG. 12 is a shell-shaped adapter having a sound emitting hole 12A, around which a loop 18 is wound. Reference numeral 10 denotes a case prepared separately, in which a microphone 13, an amplifier 16, and a battery 20 are housed, and attached to the adapter 12. 14 is a power switch.

According to the above configuration, all the necessary elements are integrally attached to the adapter 12, so when the adapter 12 is attached to the telephone receiver, the loop 18
The sufficiently large sound magnetic flux emitted from the hearing aid is captured and listened to by the telephone pickup coil of the hearing aid.

As mentioned above, this invention has a simple configuration and is convenient to use, and it converts the sound emitted from the telephone receiver into a sufficiently large sound magnetic flux, making it convenient for people with hearing loss to make telephone calls.It has a remarkable practical effect. have
