る。 Next, 2 connected to the earphone 10 on the jack 7
When a polar plug 8 is inserted, the selector switch 6 is switched to the c side, and terminals g and h of the jack 7 are short-circuited. Therefore, the voltage applied to point a is O [V], which is lower than the reference voltage, the changeover switch 5 is in the state of being switched to the d side, and the audio output is performed by the adjustment volume 3 provided in the device.

のである。 In addition, when a three-pole plug 9 connected to the remote control transmitter 11 is inserted into the jack 7, or when a jack 12 connected to the remote control transmitter 11 is inserted,
When the plug 8 connected to the earphone 10 is inserted, the changeover switch 6 is switched to the c side, and the voltage applied to point a by the internal resistance of the transmitter side volume control circuit 13 of the remote control transmitter 11 is the standard. When the voltage becomes higher than the voltage, the changeover switch 5 is switched to the e side, and the voltage generated in the volume circuit 13 provided in the remote control transmitter 11 is transmitted to the volume 4 provided in the main body of the device to adjust the volume. It is.
