CONTROL SIGNAL GENERATION CIRCUIT USING ORAL SOUNDS

摘要

PURPOSE: A control signal generating apparatus using an oral sound is provided to enable anyone to easily control a signal generating apparatus by generating a controlling signal based on the oral sound. CONSTITUTION: A microphone(20) receives an oral sound which is generated within oral cavity. Amplifiers(40a, 40b) amplify the oral sound to multiple stages. A microprocessor(80) generates a control signal by changing the amplified signal into a digital signal. The amplification ratio of the oral sound is controlled according to the oral structure of a user by connecting to the terminal of the amplifier. The microprocessor respectively stores a teeth contact sound and a tongue puffing sound in a binary code.
