Abstract

(57) [Summary] [Purpose] To obtain a television receiver that can automatically adjust the volume of the television during a call on a cordless telephone. [Configuration] A carrier wave of a cordless telephone is detected by a detection circuit 6 via an antenna 4 and a tuning circuit 5, and a volume switch 8 to which the detection signal is input controls an audio circuit 9 to change the volume from a speaker 10 to silent or low volume. automatically adjusts the volume.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to television receivers, and is particularly applicable to cordless telephones. The aim is to respond accordingly.

0002

[Conventional technology]

Traditionally, cordless phones have become popular, and you can use cordless phones while watching TV. I often use stories. If you receive a phone call while watching TV, the phone will To adjust the volume on the TV, you have to go to the TV once or You can use the remote control hand unit to adjust the volume or activate the silence switch on the phone. The first thing to do is to take some action to prevent the TV sound from interfering with calls. Common.

0003

[Problem that the idea aims to solve]

In this way, when you receive a call, turn down the volume on the TV or mute it. These movements are troublesome in the moment, and if possible, you don't want to do them. Everyone has this.

0004 This invention was developed in view of the above points, and it A TV receiver that automatically adjusts the TV volume when there is a call. The purpose is to provide an image machine.

[0005]

[Means to solve the problem]

In order to achieve the above object, the television receiver according to the present invention is a cordless telephone. a detection means for detecting the carrier wave sent from the and volume control means for switching and controlling the volume of the device to a preset volume. It is a sign.

[0006] Furthermore, in the television receiver having the above configuration, the display is performed based on the detection signal. The device is characterized by comprising a display control means for displaying a call signal on the screen. It is something.

[0007]

[Effect]

In the present invention, the detection means detects the carrier wave transmitted from the cordless telephone. is detected, the volume control means adjusts the volume of the audio circuit based on the detection signal. to a preset volume.

[0008] Further, the volume control means displays the volume of the telephone call on the display screen based on the detection signal. Display the in signal.

[0009]

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. Figure 1 is the subject of this invention. This shows the equipment configuration. In Figure 1, a base unit 1 and a handset 2 of a cordless telephone Between the When a call is made, there is always a carrier wave with a predetermined frequency. . Therefore, by detecting this carrier wave with the television receiver 3, it is possible to transmit and receive calls. The TV audio will automatically switch to the preset audio and the display screen will change automatically. A sign signal can be displayed.

0010 FIG. 2 shows a specific circuit diagram provided in the television receiver 3. As shown in FIG. In Figure 2, the carrier wave of the cordless telephone is received by the antenna 4 and the tuned circuit It is detected by a detection circuit 6 via a path 5 and converted into a DC voltage. The feeling of this detection signal The sensitivity is set by the sensitivity adjuster 7, and the detection signal is set by the volume switch 8 and the sign generation switch. input to the switch circuit 16 and operate the audio circuit 9 and the sign signal generation circuit 17, respectively. Let them make it.

[0011] The TV's audio circuit 9 will automatically respond when there is no signal from the cordless phone. It operates at the set volume, and when using a cordless telephone, the volume switch 8 from the speaker 10 at the volume set in advance using the volume switch 8. Controls the volume of the output.

0012 On the other hand, the original function of the television is to After the wave is channel-selected by the high-frequency circuit 12, it is converted to a detection signal, and the audio It is input to the circuit 9 and the video circuit 13 and output to the speaker 10 as audio and video, respectively. and is audio-visualized by the cathode ray tube 14. In addition, the cathode ray tube 14 has this A high voltage deflection circuit 15 is provided for operating the main tube.

[0013] In addition, a sign generation switch circuit operated by the carrier wave of the above cordless telephone 16 and a sign signal generation circuit 17, a sign signal is given to the video circuit 13. Then, the video circuit 13 displays a telephone call sign on the cathode ray tube 14.

[0014] Therefore, according to the above embodiment, when a call comes in while watching the TV screen, , the volume switch 8 adjusts the TV sound based on the detection of the carrier wave of the cordless telephone. The volume of the voice is automatically adjusted to silence or low volume, and the sign generation circuit 17 will display a call sign on the TV screen, allowing you to visually confirm incoming calls. At the same time, the volume of the TV audio is automatically adjusted so that it does not interfere with calls. This allows you to view the review more comfortably.

[0015]

[Effect of the idea]

As described above, according to the present invention, when you receive a phone call while watching TV, mutes or dims the TV volume based on the cordless phone's carrier wave detection. Automate volume and volume adjustment to make watching TV even more comfortable. Can be done.

[0016] In addition to the above effects, the TV screen also displays the current call image on the TV screen based on carrier wave detection. This has the effect of automatically visually confirming incoming calls.
