Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a remote control device for a television receiver, and in particular, in addition to the remote control function, it is possible to control only audio broadcasts on broadcast channels that the television receiver can receive. This invention relates to a built-in tuner remote control that has a built-in tuner function that allows reception.

[Conventional technology]

Conventionally, this type of remote control device has the function of remotely controlling only the operating mode of the receiver itself, such as switching on/off the receiver's power supply, selecting a desired channel for reception, or increasing/decreasing the volume. was. That is, a keyboard section for selecting the operating mode, and a transmission control processing section that processes the necessary data and signals based on the signal input from this keyboard section and generates a remote control signal to be transmitted to the 7-inch part of the receiver. It generally consists of a battery section that serves as a bias power source for these electronic circuits.

[Problem that the invention seeks to solve]

The above-mentioned conventional remote control device assumes that all broadcast information consisting of images and sounds is received from the TV receiver itself, such as a cathode ray tube, speaker, or earphone, so it is especially important for users who want to enjoy program broadcasts away from the receiver. Sometimes, it is unavoidable to increase the output of the receiver's speakers to make the volume louder, and as a result, there is a method of using earphones, which creates an environmental disturbance in terms of sound for people in the vicinity who do not want to receive the broadcast. , originally intended to enjoy broadcasting at a location far from the receiver using a remote control device, at least 2fn or 6f in some cases.
F! In this case, it becomes necessary to go to the receiver to attach the earphones.

This not only requires earphones with long cords, but also has the drawback that the functionality of the remote control device that satisfies the user's desire for remote control is halved.

[Means for solving problems]

The built-in tuner remote control of the present invention has conventional functions for remotely controlling operating modes such as turning on/off the TV receiver, selecting channels, and increasing/decreasing the volume. Among them, it has a tuner function circuit consisting of an antenna capable of receiving audio broadcasts, a reception circuit, a demodulation/amplification circuit, a speaker (or earphone), etc.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention.

In FIG. 1, the television receiver 7 uses a high-use AC power supply 1 as a power source, and includes a power switch 1, a low-voltage DC power supply circuit 3 for control circuit bias, a switching power supply circuit 4, and further includes:
The sensor circuit 5 detects the remote control signal 19 shown in FIG. This is a receiver that can be operated by remote control. FIG. 2 shows the circuit configuration of the tuner built-in remote control device according to the present invention. In the figure, the remote control function section 18 is powered by the battery 8, similar to the conventional device, and the keyboard 15 is used to input operation mode selections. It is comprised of a control processing circuit 16 and a transmitting circuit 17 for processing necessary data and signals based on these signals and transmitting a remote control signal 19 to the above-mentioned height circuit 5 in the receiver.

Furthermore, in addition to these, the remote control device according to the present invention has a power switch 9 for receiving power supply from the same power source 8.
a circuit 10 that selectively receives and demodulates broadcast radio waves via an antenna 12 for capturing audio broadcasts with high sensitivity;
It has a tuner function circuit 14 that includes a circuit 11 that electrically and mechanically amplifies this output signal and a speaker (or earphone) 13.

〔Effect of the invention〕

In a normal broadcast reception state, that is, when image information such as images and audio is received through the cathode ray tube and speakers from the television receiver body, only the conventional remote control function operates. However, the image information comes from the cathode ray tube in the receiver itself.
The effects of the present invention are exhibited when audio information is received by a built-in tuner. For example, the user selects a desired program broadcast using the remote control function section 18, then operates the built-in changer section 14 and listens to the audio from the remote control device 20 at hand. Therefore, regardless of the distance from the receiver body, broadcasting can be enjoyed at a relatively low volume. Of course, at this time, the speaker output of the main body of the receiver may not be provided, or it may be output at an appropriate volume for those who are near the receiver and want to enjoy the broadcast at the same time.

In addition, if you are located 5 to 6 fn away from the receiver, and you do not want the audio broadcast to leak into the housing, you can use earphones instead of the speaker for the remote control device 20. It is extremely convenient to enjoy TV broadcasts without reducing the functionality of the remote control device in half, which satisfies the needs of the user, since it is often necessary to go to the earphones with long cords and to attach and detach them from the receiver. It has a big effect.
