When the main power supply 2 is generated, it is slightly exempted. All the components in the device 1 are replaced by a moon shape. In addition, the second detection circuit 2 = element 70 is electrically connected to the main power supply a. In order to detect the main power source 214:;!: - the first set value can generate a detection signal to control the off switching unit U. The above-mentioned second and second pass signals 202 are generated by any one of the detection signals 201 = music detection switching unit 10.
