Abstract

PURPOSE:To make a call from free positions possible, by remote-controlling dial oscillation of a telephone set. CONSTITUTION:Ultrasonic waves from ultrasonic oscillator 1 are modulated according to the command from keyboard 3 and are transmitted from ultrasonic speaker 4. Meanwhile, ultrasonic microphone 5 belonging to the telephone set main body part detects ultrasonic waves and demodulates them to a dial signal by demodulator 6, and this dial signal is transmitted to the telephone set main body part corresponding to the dial part through dial setting device 7 or the dial signal of the telephone number stored in the device 7 is transmitted continuously to the telephone set main body part corresponding to the dial part by the remote control, thus the transmission by the dial is achieved. Consequently, said transmission by the dial can be remote- controlled.
