Abstract:
Provided is an impact type vibration actuator including a permanent magnet having a stopper insertion portion; a linear guide surrounding the permanent magnet; a stopper protruding into the linear guide and inserted into the stopper insertion portion; and coils provided on at least one end of the permanent magnet to provide alternately attraction and repulsion to the permanent magnet.According to the present invention, since a permanent magnet is not connected to the vibration mass, it is possible to adjust the vibration frequency in a very wide range by adjusting the frequency of the power source applied to the coil, and to adjust vibration intensity by appropriately selecting current intensity, a stopper interval, an elastic means, and the like. In addition, through this, it is possible to provide much more various haptic feedbacks than the prior art.
