Abstract

PURPOSE:To selectively and quietly listen to voice at a position separated from a voice generating device main body by receiving the signals of plural different frequencies from a voice signal conversion transmitter. CONSTITUTION:A voice signal conversion transmitter 5 to possess a function able to transmit plural frequencies (N1hz, N2hz,...Nnhz) is fitted to an earphone jack 4 or the applying voice signal conversion transmitter is incorporated in a voice generating device main body. Moreover, a receiver 9 to possess the function able to select and to receive the plural frequencies (N1hz, N2hz,...Nnhz) is fitted to a headphone or the applying receiver 9 is incorporated in a remote controller 10 linked to the earphone. Thus, voice can be listened selectively from a separate position codelessly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cordless type receiving system for a sound generator, such as a television, for selectively and quietly listening to sound at a location remote from the main body of one or more sound generators having an earphone jack. This is something related to.

Conventionally, all sound generating devices such as televisions are equipped with an earphone jack, but since the method of listening to the sound is by using an earphone cord, it is useful for people who wish to listen to the sound from a distance, such as housewives. Or, do not disturb the people sitting with you (for people who wish to listen to the audio alone, there are restrictions on the distance from which they can listen from the audio generator itself, so it is difficult to listen to the audio quietly from a distance) It was difficult to hear.

Furthermore, it has been impossible to selectively catch sounds from a plurality of sound generator bodies and listen to the sounds quietly from a remote location.

The system of the present invention eliminates this drawback.

Multiple frequencies (Nl Hz, N2
Headphones are equipped with an audio signal conversion transmitter that has the function of transmitting multiple frequencies (hz, ...Nnhz), or are equipped with the audio signal conversion transmitter in the main body of the sound generator. hz, N2
By attaching a receiving device that has the function of selectively receiving hz, ... Nnhz), or by incorporating the receiving device into a remote control device connected to earphones, you can select from a remote location cordlessly. This allows you to listen to the audio.

The following are specific effects of the present invention: Ren housewives watch TV while working. Disturbing others from a distance Listen to audio on your own without being interrupted can be done.

Mouth, in the same room! To enable a plurality of people to quietly listen to the sounds of different channels on one television set from a remote position.

C. In a large hospital room, etc., do not disturb others (you can enjoy your own TV from a distance from your bed).

Note that the present invention is not limited to televisions (radios, record players, tape recorders, VTRs,
Laser disc player/CD player/DAT
It can be generally applied to such things as
