Abstract

The embodiment of the invention provides a piezoelectric vibration motor. The piezoelectric vibration motor comprises a base, a mass block, an elastic piece and an electric control assembly. The mass block is movably arranged on the base, piezoelectric ceramic pieces are connected to the elastic pieces, the elastic pieces comprise the first elastic piece and the second elastic piece which are arranged on the two sides of the mass block, one end of the first elastic piece and one end of the second elastic piece are both connected with the base, and the other end of the first elastic sheet and the other end of the second elastic sheet are connected with the same end of the mass block; and the electric control assembly is electrically connected with the piezoelectric ceramic piece. According to the piezoelectric vibration motor provided by the embodiment of the invention, the piezoelectric ceramic pieces are connected to the first elastic piece and the second elastic piece, the piezoelectric ceramic pieces can drive the mass block to transversely vibrate through the first elastic piece and the second elastic piece after being electrified and deformed, and the vibration intensity and the vibration stability of the piezoelectric vibration motor are improved.

Description

technical field [0001] The present application belongs to the technical field of vibration devices, and in particular, the present application relates to a piezoelectric vibration motor. Background technique [0002] With the continuous development of communication technology, the functions of electronic devices are becoming more and more powerful. It is becoming more and more common to use vibration feedback for information interaction between electronic devices and users. [0003] Taking mobile phones as an example, each mobile phone will be equipped with a vibration motor. In a noisy environment, the vibration function generated by the vibration motor of the mobile phone can effectively remind people of incoming call information and text messages in a timely and effective manner. At present, the mobile phone vibration motor mainly used in the market is a rotor motor composed of a motor and a counterweight eccentric wheel installed on the rotor shaft of the motor. Howeve...
