JPH11225399A - Noiseless television receiver for aged person weak in hearing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a noiseless television receiver for an aged person weak in hearing where a high frequency transmitter that transmits an FM frequency signal allowing the aged person weak in hearing to hear a television audio signal clearly without noise and a receiver are integrated as one set. SOLUTION: A clip 10 connects to the speaker terminal of a television receiver and to an audio input terminal through a shield wire 9. A received television audio wave is given to an input adjustment circuit, a modulation circuit and an output circuit, and an FM wave is sent from the antenna 6 of a high frequency transmitter 1. The transmitted FM wave is received by a receiver 13 and heard by an earphone set at an earphone terminal 17.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a noiseless television receiver for the elderly with hearing impairment, which enables the elderly with hearing impairment to hear the sound of the television clearly and without noise.

[0002]

2. Description of the Related Art Heretofore, when a deaf old man watches television, it has become one of the troubles with his family to increase the volume of sound. Deaf people use hearing aids,
There is so much noise that you can't enjoy watching TV. Also, even if you exchange conversations, you will be worried about noise, and currently you will not use it except when you are out. Although there are stationary transmitters, the sound is distorted and noise is introduced because the receiving method is to listen with a speaker at the ear. It is said that the hearing impaired will not be able to hear the words of Sasisyseso in the treble part of the scale.

[0003]

In a conventional hearing aid, in order to receive the sound distant from the place where the sound is emitted, noise in the middle is taken into the hearing aid at the same time, and the noise is received in the ear together with the sound. Become. For this reason, it is often difficult to listen clearly even when watching TV or having conversations.

[0004] In addition, although there is a transmitter / receiver of a system that allows a user to listen to the sound of a cordless television at his / her ear, there has been a problem that the receiver has to make a loud voice in order to listen through a speaker.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, a noiseless television receiver for the elderly with hearing impairment of the present invention, which has been variously manufactured and tested, has an input circuit for inputting a television sound wave, and an input circuit. A high-frequency transmitter provided with a modulation circuit for modulating the modulated audio wave to an FM frequency, an output circuit for outputting the modulated FM wave, and a receiver for receiving the FM wave.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In the block diagram of FIG. 1, an audio wave input and adjusted from a speaker terminal of a television is modulated to an FM frequency by a modulation circuit, and the audio wave is transmitted from an output circuit. As shown in the block diagram of FIG. 4, an input sound wave of the television is converted into a sound wave by an earphone via a receiving circuit.

In the embodiment of the transmitter shown in FIG. 3, the clip (10) is connected to a terminal of a television speaker, and is connected to an audio input terminal through a shield wire (9). The input television sound wave is transmitted through an input adjustment circuit, a modulation circuit, and an output circuit to transmit an FM wave from an antenna (6) of the high-frequency transmitter (1).

The transmitted FM wave is received by a receiver (13) shown in FIG. 7 and received by an earphone set to an earphone terminal (17).

In another embodiment, a microphone is set in an audio input terminal (8) of a high-frequency transmitter (1), placed immediately before a television speaker, and a sound wave of the speaker is inputted to adjust the circuit. Use to adjust the sound wave. Then, the signal may be modulated to the FM frequency by the modulation circuit.

[0010]

Since the present invention is configured as described above, it has the following effects.

FM transmitted from the high-frequency transmitter (1)
Since the frequency wave is a clear sound wave without any noise, the receiving side can hear clear words.

[0012] Since the FM frequency wave transmitted by the high frequency transmitter can be received by the receiver within a distance of 15 meters, the FM frequency wave can be heard right by the deaf elderly person. Therefore, the loudness of the voice did not cause any trouble to others.

Further, when a high-frequency transmitter with a speaker is placed in a large number of people who are talking and listening with a receiver, the conversation can be smoothly performed, which greatly contributes to family reunion.

[0014] That is, even when the user is away from the television, the sound can be clearly heard at the ear. Since no noise is generated by using the earphone, the deaf elderly can participate in the conversation. It is a gentle TV receiver for the hearing impaired.
