    Abstract: A vibrating actuator is disclosed, comprising: a magnetic part including at least two magnets (1) arranged with same polarities facing each other; a receiving part including a hollow member (4) with a cavity (5) for receiving the magnetic part and at least one coil (2) wrapped around the hollow member (4) and fixed thereto; elastic elements (6) interconnecting the magnetic part and the hollow member (4); and a chassis (7). In one aspect, the magnetic part is fixed to the chassis (7) via attachment elements (8, 10) such that the magnetic part, the attachment elements (8, 10) and the chassis are stationary, and the receiving part performs a linear movement with changing direction causing the vibration when an alternating current passes through the coil(s) (2).
