PROBLEM TO BE SOLVED: To provide an artificial larynx capable of obtaining the voice of a desired pitch in a simple structure.
SOLUTION: The artificial larynx includes: a cylindrical body 2 to be a body provided with an insertion hole 4 for introducing exhaled air a piston 3 movably inserted to the insertion hole 4 and moved to one side by an expiratory pressure an outflow hole 8 for communicating the insertion hole 4 and the outside on the other side of the piston 3 and an elastic vibrator film 11 vibrated by the exhaled air flowing out from the outflow hole 8 and changed in tension by the movement to one side of the piston 3. When the exhaled air is introduced to the insertion hole 4, the piston 3 is pressed to one side by the pressure, the elastic vibrator film 11 is stretched, and the exhaled air passes through the outflow hole 8 and vibrates the elastic vibrator film 11. In such a manner, the piston 3 receives the expiratory pressure, pressed to one side and stopped at a position balanced with the tension of the elastic vibrator film 11, and since the vibration of the elastic vibrator film 11 is changed by the tension and length, especially the tension, a vibration frequency can be changed by the expiratory pressure.
