Patent ID: 11302861

Abstract:
A hybrid actuator is provided in which a piezoelectric element and an actuator are incorporated with each other. The hybrid actuator includes: a housing; a stator secured to the housing and having a coil; a vibrator having a permanent magnet configured to vibrate due to a mutual electromagnetic force with the stator; an elastic member configured to elastically support the vibrator relative to the housing; a piezoelectric element attached to one surface of the housing; and an F-PCB (flexible printed circuit board) applying an electric current to the piezoelectric element and the coil inside the housing. A part of the F-PCB extends outside the housing. Input terminals are formed on the part of the F-PCB which extends outside the housing. The input terminals are configured to receive a vibration signal and an audio signal so that the hybrid actuator can reproduce both the vibration signal and the audio signal.
