Reference numeral 5 denotes a fifth button for increasing the volume of the speaker provided on the TV side, and reference numeral 306 denotes a sixth button for decreasing the volume of the speaker provided on the TV side.

The remote controller includes a control unit 5a and a memory 5b. The control unit 5a monitors the operation signals of the buttons, counts the number of times the buttons are operated, and, for example, every time a button is operated, one for example. The volume can be increased or decreased step by step.

Reference numeral 307 denotes a setting start button, and 308 denotes a setting end button. The control unit operates the third button 303 between when the setting start button 307 is operated and when the setting end button 308 is operated. The number of times the button 5 has been operated and the number of times the fifth button 305 has been operated are stored in the memory 5b. Reference numeral 310 denotes an infrared light emitting unit for remotely adjusting the output of a speaker such as a TV. Reference numeral 310 may be a wireless transmission unit instead of the infrared light emitting unit.

Next, a method of cooperatively controlling the volume of the speaker provided on the TV side and the volume of the speaker provided on the chair body by the remote controller will be described.

First, a TV as an external audio system has a built-in TV that amplifies an externally input audio signal every time it receives an infrared ray including a volume increase instruction signal or a volume decrease instruction signal from the infrared light emitting section 310. It is assumed that the amplification of the amplifier 8 is increased or decreased by 2 dB. On the other hand, whenever the amplifier 4 on the chair body side inputs a volume increase instruction signal or a volume decrease instruction signal from the remote controller 5,
It is assumed that the amplification degree of the music chair built-in amplifier 4 for amplifying an audio signal input from an external unit is increased or decreased by 1 dB.

Next, by operating the fourth button 304 and the sixth button 306, the audio signal output from the speaker of the music appreciation chair and the speaker of the TV cannot be heard, or the audio signal output from the speaker of the TV cannot be heard. Adjust to be able to. Next, a setting start button is operated to start setting of the operation frequency ratio (R value) described later. Then the third
Button 303 is operated a plurality of times, and the fourth button 3
By operating the 04 and the sixth button 306, the volume level of the audio signal output from the speaker of the TV and the speaker of the music appreciation chair and listened to is adjusted to be substantially the same.

Here, it is assumed that when the third button 303 is operated six times and the fifth button 305 is operated three times, the volume levels output from the TV and the speaker of the music appreciation chair are both 6 dB. . Next, the setting is completed by operating the setting completion button.

The control unit calculates the R value as R = (the number of times the fifth button is operated) / (the number of times the third button is operated) = (3 /
6) It is calculated that = 0.5. Further, based on the calculated R value, the control unit may perform, for example, a first
Is operated twice, a signal instructing to increase the amplification degree of the amplifier 4 of the music appreciation chair is output twice, and the amplified signal is transmitted to the TV built-in amplifier 8 via the infrared light emitting unit 310. The signal for increasing the degree (2 × 0.
5) = Output once. Therefore, the first button 301
Is operated twice, as the volume level output from the speaker of the music appreciation chair increases by 2 dB, the volume level output from the TV speaker also increases by 2 dB.

On the other hand, when the second button 302 for decreasing the volume is operated, the control unit, for example, when the second button 302 is operated twice based on the calculated R value,
A signal for instructing to reduce the amplification of the amplifier 4 built in the music appreciation chair is output twice, and the infrared light emitting section 3 is output.
A signal for reducing the degree of amplification is output to the amplifier 8 having a built-in TV via (2 × 0.5) = 1 once through 10. Therefore, when the second button 302 is operated twice, as the volume level output from the speaker of the music appreciation chair decreases by 2 dB, the volume level output from the TV speaker also decreases by 2 dB.

Next, as another example, each time the TV as an external audio system receives an infrared signal including a volume increase instruction signal or a volume decrease instruction signal from the infrared light emitting section 310, it converts an externally input audio signal. It is assumed that the amplification degree of the amplifier 8 to be amplified is increased or decreased by 0.8 dB. On the other hand, the amplifier 4 on the chair body side increases the amplification degree of the amplifier 4 for amplifying the audio signal input from the external unit by 1 dB every time the volume increase instruction signal or the volume decrease instruction signal is input from the remote controller 5 as in the above-described example. Only increase or decrease.

Next, by operating the fourth button 304 and the sixth button 306, the audio signals output from the speaker of the music appreciation chair and the speaker of the TV become inaudible, or are slightly received. Adjust to be able to. Next, a setting start button is operated to start setting of the operation frequency ratio (R value) described later. Then, the fourth
By operating the button 304 and the sixth button 306, the volume level of the audio signal output from the speaker of the music appreciation chair and the TV speaker is adjusted to be substantially the same. Here, it is assumed that when the third button 303 is operated four times and the fifth button 305 is operated five times, the volume levels output from the TV and the speaker of the music appreciation chair are both 4 dB. Next, the setting is completed by operating the setting completion button.

The control unit calculates the R value as R = (the number of operations of the fifth button) / (the number of operations of the third button) = (5 /
4) It is calculated that = 1.25. Further, based on the calculated R value, for example, when the second button 302 for decreasing the volume is operated eight times, the control unit instructs to decrease the amplification degree of the amplifier 4 of the music appreciation chair. Signal 8
And outputs a signal (8 ×) to the TV built-in amplifier 8 via the infrared light emitting unit 310 to reduce the amplification degree.
1.25) = 10 outputs. Therefore, when the second button 302 is operated eight times, the volume level output from the speaker of the music appreciation chair decreases by 8 dB, and the volume level output from the TV speaker also decreases by 8 dB.
Decrease.

FIG. 4 is a diagram for explaining the processing of the control unit 5a. First, in step 1, the user of the music appreciation chair 1 operates the TV main body side buttons (the fifth button and the sixth button) of the remote controller to adjust the volume of the TV side speaker to the minimum audible volume. . In step 2,
Chair button on the remote control chair (third button and fourth button)
Button) to adjust the volume of the chair body side speaker to the minimum audible volume. In step 3, the setting start button 307 is operated to start setting the R value. In step 4, the third button 303 is operated to set the volume of the speaker on the chair side to an arbitrary level. In step 5, the number of times of operation of the third button 303 is counted. When the fourth button 304 is operated, the number of times of operation of the third button 303 is added, and the fourth button 304 is operated.
The value obtained by subtracting the number of operations of the third button 303 is set as the number of operations of the third button 303.

In step 6, the fifth button 305
To set the volume of the TV-side speaker to an arbitrary level. In step 7, the number of times of operation of the fifth button 305 is counted. When the sixth button 306 is operated, the number of times of operation of the fifth button 305 is added, and the value obtained by subtracting the number of times of operation of the sixth button 306 is set as the number of times of operation.

In step 8, the user compares the volume level output from the speaker of the music appreciation chair with the volume level output from the TV speaker. If the volume levels substantially match, proceed to step 9; Returns to step 4. In step 9, the setting end button 308
To end the R value setting operation. In step 10, the control unit sets the R value to R = (fifth button 305
Is calculated based on (the number of operations of the third button 303) / (the number of operations of the third button 303. In step 11, the calculation result is stored in the memory 5b, and the setting process is terminated. For example, when the first button is operated n times, a signal instructing to increase the amplification of the amplifier 4 of the music appreciation chair is output n times, and the TV amplifier 7 is transmitted via the infrared light emitting unit 510. (N × R) = (2 × 0.5) = 1 time.

As described above, the third button 303
After the setting by the sixth button 306, the volume of the speaker of the music appreciation chair and the volume of the speaker of the TV are simultaneously increased at substantially the same volume level only by operating the first button 301 or the second button 302. Or it can be reduced. Note that the remote controller 5 has a learning function, that is, a function of operating a learning operation button to store volume increase instruction data and volume decrease instruction data emitted from the remote controller attached to the TV. TV volume control.
