Abstract
A resonant vibration actuator includes a casing, a mover, a plurality of electromagnet sets, two elastic suspensions, and a connecting circuit. The casing is provided with connection terminals for connection on the outside of the casing. The mover has a mover frame, a plurality of permanent magnet units, and two magnetic backs. The permanent magnet units and the magnetic backs are arranged in the mover frame and the electromagnet sets are arranged between the permanent magnet units. Elastic suspensions are connected to the casing and the mover respectively through two connection portions at both ends. The connecting circuit is used to connect the electromagnet sets and the connection terminals outside the casing. By energizing the electromagnet sets, the electromagnet sets act on the permanent magnet units to make the mover move relatively in the casing to generate vibration.
