Abstract

PROBLEM TO BE SOLVED: To allow an audibly handicapped person to use a mobile telephone set such as a portable telephone set or a PHS. SOLUTION: An input output terminal 21 of an adaptor 20 is connected to an external input output terminal 11 of a mobile telephone set 10 and a cord 22 is extended to isolate the mobile telephone set 10 from the adaptor 20 sufficiently. A reception signal received through the cord 22 is amplified by an amplifier circuit 23 and sound quality is corrected by a sound quality correction circuit 24, a sound volume is adjusted by a sound volume adjustment variable resistor 25 and fed to an induction coil 26, from which an induction magnetic field is generated. The induced magnetic field is heard by a hearing aid 30 in the T mode.

2. Description of the Related Art In the case of a conventional telephone for a subscriber's line or a public telephone in a home, some auxiliary means for a hearing-impaired person have been considered. One is that the telephone body can increase the reception volume, and it can be used even by elderly people who have not used a hearing aid but have a slightly distant ear. The second method is to use the T mode of the hearing aid. This is a method in which a coil is built in the receiver and a coil is also built in the hearing aid, and coupling is performed with an induced magnetic field. Particularly, in the case of a public telephone, there is an advantage that it is hardly affected by ambient noise and only the voice of the other party can be heard, so that it is easy to listen clearly. Further, since these methods cannot be used unless the telephone itself has the function, a telephone coupler is considered as an auxiliary tool. In this method, the sound is picked up by a microphone, picked up by a microphone, amplified, and a sound is output from a speaker or a magnetic field is output from a coil. There is an advantage that the hearing-impaired person can carry it and use any telephone.

On the other hand, mobile phones and P
"Mobile phones" such as HS have become widespread, and it is considered that there is a potential demand for hearing-impaired people. However, there are problems with telephone hearing aids that are unique to mobile telephones that are not available to subscriber telephones and public telephones, and that many hearing-impaired people cannot use mobile telephones. Hereinafter, the reason will be described.

[0005] First, the reception sound volume amplification is performed. It is not impossible, but not practical, to amplify a mobile phone alone until the listener can hear it without a hearing aid. This is because, in the case of a mobile phone that is expected to be carried around at all times, it is desirable to reduce power consumption as much as possible, extend the usable time per charge, and further reduce the size and weight. Even if the received sound volume can be increased, if the received sound volume is too high, it is likely to cause trouble to surrounding people. This is also a problem in portable radios and headphone stereos, and may be even more serious for phones that do not completely adhere to the ears in normal usage.

Therefore, it is conceivable to use a hearing aid together. If the hearing aid can be used together, the received sound volume is amplified on the hearing aid side, and since the hearing aid earphone is usually closely attached to the outer ear, there is no problem of sound leakage. However, listening to mobile phones with a hearing aid has a major problem.

That is, the hearing aid picks up noise caused by radio wave transmission. The output of a mobile phone is different from that of a mobile phone or PHS, but is connected to a base station by radio waves. When the hearing aid is moved closer to the mobile phone, radio waves emitted by the mobile phone enter the electronic circuit of the hearing aid and generate large noise. Therefore,
Even if a conventional subscriber telephone or public telephone coupler or the like is mounted on a mobile telephone, it is impossible to listen because the distance between the hearing aid and the mobile telephone is too short.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A hearing aid adapter for a mobile phone according to the present invention converts a signal output from an external input / output terminal of the mobile phone into a cord having a length necessary to separate the hearing aid from the mobile phone by an appropriate distance. To the sound quality correction circuit and the volume adjustment circuit. The sound quality correction circuit and the volume adjustment circuit correct the difference between the microphone mode and the T mode of the hearing aid and the hearing type of the hearing-impaired person, and finally send a signal to the induction coil. An induction magnetic field generated by the induction coil is received in the T mode of the hearing aid. At this time, no noise is generated because the distance from the mobile phone is large. On the other hand, similarly, a signal picked up by a built-in microphone is input to an external input / output terminal of the mobile phone.

Next, the operation will be described. Mobile phone 1
0 is received from the output terminal a of the adapter 20
, And the sound quality correction circuit 24 corrects the frequency characteristics. Usually, the sound quality of the hearing aid 30 is adjusted in accordance with the hearing ability of a hearing-impaired person, but this adjustment is mainly performed for microphone input. Although it is desirable for the hearing aid 30 that the sound quality does not change even with a T coil input, the sound quality and sensitivity often differ in practice. This sound quality correction circuit 24 corrects the sound quality.
For example, a low-pass / high-pass 2ch shelving type equalizer, a peaking type graphic equalizer, and the like are conceivable. The reception signal whose sound quality has been corrected is sent to a volume adjustment volume (volume adjustment circuit) 25.
This is performed together with the amplification circuit 23 so that the volume of the hearing aid 30 is constant and the same listening volume as the microphone input of the hearing aid 30 is corrected. This is for adjusting appropriately. The received signal whose sound quality and volume have been adjusted
It is sent to the induction coil 26 and converted into an induction magnetic field. The hearing aid 30 receives this induction magnetic field in the T mode and receives the hearing.
