PURPOSE: A supersonic telemeter for outputting voice is provided to carry out the voice alarm about the exact distance by compounding the alarm voice data according to the fields and amplifying it into the analog voice and outputting it to the speaker. CONSTITUTION: A supersonic telemeter for outputting voice includes a supersonic wave transceiving portion(10), a distance calculating portion(20), a micro controller(30), a memory(60) for storing voice data, an analog voice converting portion(40), a voice amplifying portion(50), a volume controlling portion(70) and a speaker(80). The supersonic wave transceiving portion(10) transmits the supersonic wave and receives the reflective wave of the supersonic wave. The distance calculating portion(20) controls the supersonic wave sending/receiving portion(10) and calculates time between the sent supersonic wave and the received supersonic wave into the distance. The micro controller(30) outputs the digital voice data according to the distance data. The memory(60) for storing voice data stores the digital voice data. The analog voice converting portion(40) converts the digital voice data into the analog voice. The voice amplifying portion(50) amplifies the analog voice signal. The volume controlling portion(70) controls the degree of the voice amplification of the voice amplifying portion(50). The speaker(80) outputs the analog voice signal.
