Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wireless remote control device for a device having an audio output, such as a television receiver or a stereo device.

Conventional technology Sound output from a device such as a stereo system that is generally equipped with a wireless remote control function is either played through speakers built into the main unit or speakers installed around it, or played through a headphone terminal provided on the main unit. Either method is adopted in which the music is played back through connected headphones.

Problems to be Solved by the Invention However, with this method of reproducing sound output, if you want to listen to music alone without disturbing those around you, you have to use the headphone terminal on the main unit, which makes it difficult to use the main unit's functions. Even though it can be controlled remotely wirelessly, the problem is that you have to go all the way to the location where the device is installed and connect the headphones. Furthermore, when using headphones, there is a problem in that the range of use is limited by the length of the cord of the headphones being used.

The present invention solves these conventional problems and provides a wireless remote control device that can reproduce music, etc. through headphones regardless of the installation position of the device body.

Means to Solve the Problems The wireless remote control device of the present invention has a built-in transmitter for a minute output that is modulated by the acoustic signal inside the main body that outputs the acoustic signal, and wirelessly controls the functions of the main body. The remote control transmitter has a built-in receiver that can receive the output of the transmitter, and has a headphone terminal for outputting the received signal from the receiver,
The remote control transmitter is controlled by a switching circuit linked to the headphone terminal.

Effect: According to the above-described configuration, when headphones are connected to the headphone terminal of the remote control transmitter, the linked switching circuit operates, a control signal is transmitted from the remote control transmitter, and the main body receives the signal. It functions to stop the main unit's acoustic signal output and operate the micro output transmitter built into the main unit, and the receiver built into the remote control transmitter allows the sound from the main unit to be transmitted regardless of the installation location of the main unit. It becomes possible to receive signals.

The operation of the wireless remote control device configured as described above will be explained below using the drawings. In the figure, the main body 1 operates an input selection circuit 8 based on a signal transmitted from a remote control transmitter 17 in response to an input selected by a switching circuit 18 of a remote control transmitter 2 and received by a remote control receiver 6. tuner 13
, a signal from the tape deck 14 or player 16 is selected by the main unit function control unit 7, and after amplifying the input signal by the preamplifier 11, the main unit control unit 7 attenuates the signal with the volume control unit 9 to a desired level, and then outputs the signal to the main unit. The audio signal is amplified again by the amplifier 12 and outputted to the speaker 6 connected to the output of the main amplifier 12 or the headphones connected to the headphone terminal 4. This is the same as before.

Here, when headphones are connected to the headphone terminal 19 of the wireless remote control transmitter 2, the connected headphone plug pushes up the terminal 19b and makes contact with the terminal 19a. Then terminal 19b and terminal 19c
terminal 1 by the voice coil of the headphones connected between
9a is indirectly grounded. Therefore, terminal 1
Through the switching circuit connected to 9a, the transmitter 1
A signal indicating that headphones are connected can be sent to the remote control transmitter 2.

In the main body 1, this signal is received by the receiving section 6, the main body function control section is operated, and the power supply switch is switched from the main amplifier 12 to the minute output transmitter 3. Then, a weak radio wave modulated by the input signal connected by the input selection circuit 8 of the main body 1 is emitted from the transmitter 3. This is received by the receiver 16 built into the remote control transmitter 2,
A signal obtained according to the input selection circuit 8 of the main body 1 is output to headphones connected to the headphone terminal 19.

As described above, according to this embodiment, the main body 1 that outputs the acoustic signal
There is a small output transmitter 3 modulated by the acoustic signal inside the

By interlocking the remote control transmitter 17 when headphones are connected to the headphone terminal 19,
sends a signal indicating that the headphones are connected to the main unit, and
The transmitter 3 is operated by switching the power supply switch 10 to the minute output transmitter 3 side by the main body function control section 7 through the remote control light receiving section 6 of the remote control transmitter. By receiving the sound at the receiver, remote control of the main unit 1 is possible regardless of the installation position of the main unit 1, and the sound selected by the input selection circuit 8 of the main unit 1 is transmitted through headphones connected to the headphone terminal 19. Since the signal can be heard and the operation of the main amplifier 12 of the main body is stopped at the same time, it is possible to enjoy music without disturbing others and to reduce the power consumption of the main body 1.

Although this embodiment deals with a monophonic 7-channel system, a stereo 7-channel system can also be handled in exactly the same way.

As described above, the present invention has a main body that outputs an acoustic signal.
A remote control transmitter that is equipped with a minute output transmitter that is modulated by the acoustic signal and that wirelessly controls the functions of the main unit has a built-in receiver that can receive the output of the transmitter, and a headphone for the reception output. A switching circuit linked to the terminal operates the remote control function, stops the sound output of the main unit, operates the transmitter built into the main body, and receives the output by the receiver built into the remote control transmitter. This allows you to listen to music using headphones connected to the remote control transmitter, completely independent of the unit's installation, and by turning off the power to the main unit's main amplifier, not only will it not disturb others, but it will also reduce the power consumption of the unit. It is also possible to reduce mental energy.
