Abstract

PURPOSE:To implement remote control used for channel switch-over and the like of a TV by utilizing, for instance, a dog's pipe as its oscillation source. CONSTITUTION:A sound wave is received by a microphone 1, amplified and filtered by circuits 2, 3, rectified by a diode 6, and applies a signal to a transistor Tr 7. When the signal is applied to the Tr 7, a capacitor 8 starts its discharge, Tr 10 becomes its contnuity and sts FF 16. Set output of the FF 16 is applied to and-gate 19, and when the other input of the and-gate 19 is applied from a monostable circuit 17 after a specified time(1 sec.) from receive of the sound wave, the and-gate 19 performs its output, through this, remote control device to control electric circulation of a load 25 can be obtained. When a sound wave continues not less than 0.9 sec., the discharge of condenser 8 is continued, and owing to this the transistor 13 has come to its continuity, the FF 16 is reset, there is no output of the AND gate 19, the load 25 has no electric circulation, and a noise signal is blocked.
