Loudspeaker for Low Frequency Signal Driven by Four Piezoelectric Ultrasonic Motors
The authors have been developing a completely new direct-radiator loudspeaker construction which is driven by continuous revolution of piezoelectric ultrasonic motors. It converts continuous revolution of ultrasonic motors to reciprocal motion of a cone radiator. This loudspeaker shows almost flat phase frequency characteristics in low frequency region, because its radiating motion includes no resonance in the working frequency region. Therefore it is useful for radiation of the lowest frequency part of audio signal. At this convention, the authors are going to present a practical model of this loudspeaker driven by co-operation of four ultrasonic motors.
