ABSTRACT:
A drive frequency control system is used for a vibration driven motor including a vibrating member which generates a vibration therein upon application of a frequency signal to an electro-mechanical energy conversion element therein, and which uses the vibration as a driving force. The system includes a power supply circuit for supplying an electric power to the vibration driven motor, and a detection circuit for detecting a power supply voltage level of the electric power supplied by the power supply circuit, the detection circuit determining whether the power supply voltage level is less than a predetermined voltage level. A control circuit performs frequency control of the frequency signal of the basis of the determination of the detection circuit.
