JPH04156033A - Radio conversation device with telephone line connection function for person hard of hearing - Google Patents

Abstract

PURPOSE:To hold usual conversation and communication by a telephone by comprising this device of a portable transmitter, a receiver, and a telephone set connection device, and attaching a transmitter on the telephone set connection device. CONSTITUTION:The telephone set connection device 1 is equipped with a telephone line connection terminal 4, a telephone set connection terminal 5, and a transmitter connection terminal 6. When the transmitter 2 is connected to the transmitter connection terminal 6, a speech signal is transmitted from the antenna of the transmitter to the receiver 3, and it is received via the receiver 3, and also, a transmission signal is sent to an opposite talker by using a microphone provided at the transmitter 2. Thereby, it is possible to use the device as a hearing aid by connecting to a telephone set, and to hear the voice of a separated opponent by the combination of the transmitter and the receiver.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical field to which the invention pertains The present invention relates to a wireless conversation device comprising a transmitter and a receiver having the function of connecting to a telephone line.

(2) Conventional Technology A telephone device using a wireless system consists of a main device and a mobile device connected to a telephone line.

(3) Problems to be Solved by the Invention However, the range of use of conventional devices is limited by the transmission output. On the other hand, wireless devices such as transceivers are also devices that are intended to be used within an applicable distance, and cannot be connected to a telephone line for communication. Hearing aids used by people with hearing loss are devices that amplify and transmit only the sound input to the microphone, and the microphone and amplification section are either integrated or connected by wire, and are used to hear surrounding sounds. This device was designed to be easy to use, but the microphone and amplification part were made into a wireless circuit, and the transmitter part had a telephone connection function, and by removing it and using it, you could hear the voice of the other party. has not been proposed so far.

The purpose of the present invention is to solve the inconvenience of hearing aids that cannot hear the voice of a person who is far away, and to provide hearing-impaired people with daily conversation and telephone communication functions by having a connection function with a telephone. .

(4) Structure and operation of the invention The present invention consists of a portable transmitter, a receiver, and a telephone connection device, and by adding a transmitter to the telephone connection device, it is possible for hearing-impaired people to have daily conversations and communicate by telephone. The main feature is that

In other words, it has both the receiving function of a receiver or cordless telephone and the function of a hearing aid, and when attached to the transmitter or telephone connection device, it becomes the receiving part of the cordless telephone, and when detached, it serves as a hearing aid. With conventional technology, hearing aids are placed at a distance. This is different because not only could it not be used to talk to other people, but it also did not have the ability to connect to a telephone.

(Embodiment) FIG. 1 is a detailed diagram of the present invention, in which 1 is a telephone connection device, 2 is a transmitter, and 3 is a receiver.

In FIG. 1, a case will be explained in which a hearing-impaired person communicates by telephone. The telephone connection device 1 includes a telephone line connection terminal 4. Telephone connection terminal 5. There are 6 transmitter connection terminals.

When the transmitter 2 is connected to the transmitter connection terminal 6, the call signal is transmitted from the antenna of the transmitter to the receiver 3, and can be heard through the receiver 3, and the transmitter signal is sent to the receiver 3. is sent to the other party using the microphone located at the other end.

FIG. 2 is a block diagram showing the functions of the telephone connection device 1. As shown in FIG. When the power supply (not shown) of the telephone connection device 1 is in an "off" state, the telephone line is connected to the telephone side by the switching unit 7, and the telephone can make and receive calls in wired communication mode as a normal telephone.

Next, when using wireless call mode, transmitter connection terminal 6
When the transmitter is connected to the transmitter and the power is turned on, the telephone line passes through the controller 8 and is connected to the transmitter connection terminal 6 from the transmitter 2.

FIG. 3 is a block diagram showing the functions of the transmitter 2. A received signal from the telephone connection device 1 passes through a mixing circuit 9 and a modulation/amplification circuit 10, and is output as a radio wave from an antenna. On the other hand, a transmission signal is input from the microphone, is switched by the microphone switching unit 11, and is sent to the telephone connection device t.
1 and connected to the telephone line. The filter circuit 12 and the sound quality adjustment circuit 13 are used when used as a hearing aid, which will be described later.

FIG. 4 is a block diagram showing the functions of the receiver 3. Radio waves transmitted from the transmitter 2 are received by the antenna of the receiver 3 and sent to the coupling circuit 14. Floton end circuit 15. Detection circuit 16. The signal passes through the amplifier circuit 17 and is again output from the coupling circuit 14 to the earphone. When the output level of the detection circuit 16 is below a certain value, the squelch (SQL) circuit 18 controls the output of the amplifier circuit 17 so that it is not transmitted.

Each circuit of the transmitter 2 and the receiver 3 is driven by a respective power source (not shown) made of a rechargeable secondary battery or a dry battery, but since this is well known, a detailed explanation will be omitted.

A case will be described in which the transmitter 2 and receiver 3 are used as a wireless hearing aid.

In this case, in FIG. 3, the transmission signal is transmitted from the microphone switching section 11 to the filter circuit 12. Sound quality adjustment circuit 13.
Mixing circuit 9. The signal passes through the modulation/amplification circuit 10 and is transmitted as a radio wave from the antenna. Here, the filter circuit 12
The sound quality adjustment circuit 13 will be explained. Until now, the sound quality adjustment function has generally been a function built into the receiver side, but since the receiver 3, which replaces a hearing aid, is used by specific users, the transmitter 2 has a filter circuit 12 and a sound quality adjustment function. By providing an adjustment circuit 13 and adjusting the sound quality on the transmitter 2 side in advance, ambient noise of the transmitter 2 can be suppressed and sound quality characteristics suitable for a specific user can be obtained.

FIG. 5 and FIG. 6 are diagrams showing the state of use.

FIG. 5 is an example of use via the telephone connection device 1, and shows a state in which a hearing-impaired person is using the telephone in wireless communication mode.

Figure 6 shows the transmitter 2 removed from the telephone connection device 1, the transmitter 2 carried by a person with normal hearing, and the receiver 3 carried by a person with hearing loss.
This shows an example of its use as a wireless hearing aid.

The distance between the two is close enough that a hearing person can directly hear the sounds produced by a hearing-impaired person through an air medium.

As can be seen from the above results, it is possible to use the hearing aid by connecting it to a telephone, which was not possible in the prior art, and to hear the voice of a distant party by combining the transmitter and the receiver.

(5) As described in detail of the invention, according to the present invention, a hearing-impaired person can not only have a conversation with a hearing person located far away, but also be able to connect to a telephone line using a telephone connection device. This has the advantage that it can also be applied to telephone communications.
