Abstract

PURPOSE:To prevent a load remote controller, which uses a sound wave close to the upper limit of an audio frequency as a medium, from malfunctioning by allowing the controller to respond only to a sound wave continuing for a fixed time. CONSTITUTION:A sound wave arriving at microphone 1 from direction A is amplified 2 and its low-frequency component is cut by filter 3; and the wave is rectified 6 and inputted to transistor Tr9 via inversion amplifier 7. Capacitor 35 is charged by constant direct current power supply 34 to a fixed value and then, FF37 is set via trigger diode 36 after a fixed time. With no arrival sound wave, Tr9 conducts and capacitor 35 is shorted. Once the sound wave arrives, the output of circuit 7 be comes zero, Tr9 is unconducted to charge capacitor 35, and a pulse are inputted to monostable circuit 29 and then to AND circuit 28 after a fixed time. When the charge of capacitor 35 reaches a fixed value, capacitor 18c is charged and on the end of the arrival of the sound wave after a fixed time, a pulse is supplied to monostable circuit 30, thereby setting FF37.
