Abstract

PURPOSE:To enjoy television broadcasting without bothering neighbors by incorporating a speaker in a remote control and emitting the sound of a broadcast station received by a television receiver. CONSTITUTION:The output side of a low frequency amplifier circuit 10 is connected to a remote control with built-in speaker 15 by switching a speaker connection switching circuit 12. The power source connection/disconnection part 20 of the remote control 14 is operated, and a power source is applied by controlling a power source circuit by a channel selection controller 17. Thence, the receiving station switching part 18 of the remote control 14 is operated, and a receiving channel is switched to a desired one by controlling the tuning element of a tuner 1 by the channel selection controller 17. Moreover, the sound volume adjusting part 19 of the remote control 14 is operated, and a sound volume is set at a desired sound volume by controlling the sound volume control circuit 11 of the low frequency amplifier circuit 10 by the channel selection controller 17. In this way, the sound of a desired broadcast station received by the television receiver emitted from the remote control with built-in speaker 15 can be heard.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control of a television receiver which enables people to enjoy television broadcasting without disturbing others.

[0002]

2. Description of the Related Art In order to watch and enjoy a television broadcast program of your choice, you can turn on the television receiver directly from the operation section of the television receiver body or from a remote location using a remote control, I was switching to the channel of the station and adjusting to the desired volume. The viewer is
Listen to the sound of the program you are watching with the sound radiated from the speaker built into the TV receiver, or sometimes, insert the earphone plug into the earphone jack provided on the TV receiver and I was listening to the sound emitted.

[0003]

[Problems to be Solved by the Invention] In a place where a large number of people are staying in one room such as a hospital or a nursing home for the elderly, when trying to enjoy a TV program of their choice, the TV receiver is generally viewed. Since it is placed at a certain distance from the person, the sound emitted from the speaker built into the television receiver is required to have a certain volume or more. Therefore, not only the audience but also the people around it can hear the sound of the broadcast program. Those who are not watching the broadcast program hear it as noise and feel uncomfortable.

Further, when a plurality of people simultaneously watch different TV broadcast programs in the same room, the sounds are mixed and not only people around but also the people watching the TV feel uncomfortable. It will be. Furthermore, if the sounds are mixed together and become difficult to hear, the volume of the user's television is further increased to make it easier to hear, which causes further discomfort to those around him.

As a method of making the sound of the broadcast program being viewed inaudible to the people around it, there is a method of wearing earphones in the ear to listen to it. With this method, people around you do not hear it and do not make noise, but tired when listening using earphones for a long time. Also, if you listen while lying down and move your body, the earphones may easily come off your ears. Furthermore, compared to the speaker, the earphone cannot radiate good sound quality from the earphone, and it is difficult to enjoy sound, especially music, with good sound quality. The present invention has an object to solve the above problems.

[0006]

[Means for Solving the Problems] In order to solve the above problems,
The remote control of the present invention is a remote control for remotely turning on / off the power of the television receiver, adjusting the volume, and selecting a broadcast receiving station. It is characterized in that the sound of the received broadcasting station is emitted.

[0007]

[Advantages and effects of the invention] The speaker built in the remote control emits the sound of the broadcasting station received by the television receiver so that it can be heard by the viewer. Therefore, the remote control, which is the source of the sound, is close to the ear. You can put it in and listen. As a result, the volume of sound emitted from the speaker can be kept low. As a result, others in the same room will not hear and will not bother you.

Even if the user lays down and listens and moves the body, there is no problem that the ear easily separates from the ear unlike the earphone. In other words, you can move your body freely.
Also, since the sound is radiated from the speaker, it is easier to radiate the sound with good sound quality as compared with the earphone. Especially good results can be obtained for music appreciation.
