BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound reduction device for temporarily reducing or silencing the sound of a television, and more particularly to a sound reduction device associated with the use of a telephone installed in the same room. , Or anything that silences.

[0002]

2. Description of the Related Art Conventionally, telephones have been provided with a switch that is turned on and off by the weight of the receiver so as to detect the pick up of the receiver and activate the telephone line.
(Hooking up the handset here means transmitting and receiving, so it is a concept that includes a button switch of a cordless telephone.) Also, a commercially available television set has a television set in the same room as the telephone. In case, a mute function is provided that can temporarily mute the sound so that the sound of the television does not disturb the call during a call. As a means for operating this function, a mute button is provided on the television set or a remote switch thereof.

[0003]

However, it is troublesome to operate the television set every time a call is made.
In particular, when the television set is difficult to reach or operate, for example, when the telephone is installed in the room in the opposite direction to the television set, or when there is no remote switch at hand Occasionally, there is no choice but to be patient even if there is some trouble in the call, and extra work was required to reduce the sound of the television set.

[0004]

An object of the present invention is to provide a combination of a television set provided with sound reduction means for reducing the sound volume and a telephone. This problem can be solved by providing a detachable switch for detecting the detachment of the handset in association with the detachable switch and the audio circuit of the television set, and reducing the volume of the television set when the telephone receiver is taken off. Further, the sound reduction of the volume of the television set includes silence. Further, the television set has an image plane set obliquely downward. In addition, the telephone is installed in the immediate vicinity of the television set.

[0005]

[Function] If you pick up the handset to use the telephone,
An attach / detach switch operates to send a signal to the television set to operate sound reduction means provided in the television set. That is, the volume of the television set is reduced when the handset of the telephone is disconnected. In addition, in the range of the case where the sound volume is reduced, there are cases where the sound volume is completely reduced as well as the case where the volume is simply reduced. If you simply reduce the volume, you can continue to watch TV when there is someone other than the caller in the room, and if you turn off the sound completely, the caller will be able to concentrate on only the call . Furthermore, when the sound reduction device is installed in a television set having a video surface that is mounted obliquely downward so as to be installed at a high place in a room, a telephone call can be made even when the television set is in a place where manual operation is not easy. In each case, the trouble of adjusting the volume is not required.
