The conventional remote controller is separated from the television, and since the size thereof is small, it is difficult to determine the position of the remote controller, so that the user cannot easily find the remote controller.

The present invention has been made to solve the above problems of the prior art, and an object of the present invention is to install a voice transmitter on a television, and a television voice receiver on a remote controller to listen to the voice of the television on the remote controller. The present invention provides a television audio output device capable of making a sound.

Another object of the present invention is to provide an alarm generating unit in the television and a receiving unit and an output unit for receiving an alarm signal from the remote controller. To provide a device that can be easily understood.

Hereinafter will be described in detail with reference to the accompanying drawings the configuration and operation of the embodiment for achieving the object of the present invention.

2 is a block diagram of a transmitter of the audio output device of the television of the present invention. The transmitter of the present invention is implemented by adding a device capable of wirelessly transmitting a voice signal to a voice output section of a television.

A television antenna (1) for receiving a plurality of composite video signals transmitted from a broadcasting station, a tuner unit (2) for tuning a broadcast channel that a user wants to watch among the broadcast signals received by the television antenna (1), and the tuner described above An IF detector (3) for detecting intermediate frequencies in the composite video signal applied from the unit (2), and P / for separating and outputting a video signal and an audio signal from the composite video signal applied from the IF detector (3). The S separator 4, the image processor 5 and the image output unit 6, which process to display the image signal output from the P / S separator 4, on the CRT 7, the P / The audio signal from the S separator 4 is output to the speaker 10 of the television. The audio processor 8 and the amplifying unit 9 output the audio signal from the P / S separator 4. FM modulator 11 for receiving FM modulation, an alarm generator 13 for generating an alarm signal, and the FM modulation It consists of a signal supplied from the unit 11 or the alarm generating unit 13 to the audio signal transmitting unit 12 to the signal processing for transmission via the transmitting antenna 14.
