Haptic feedback actuator make use of the positive and negative piezoelectric effects of piezoelectric ceramics. When the driving voltage is loaded to it, the ceramic will produce mechanical deformation, so it causes vibration. It consists of piezoelectric ceramic and metal substrate. The product has stable performance, small and light size, and meets the requirements of thin installation. It has the advantages of low power consumption, large amplitude, fast response speed and long service life. Moreover, it can freely change amplitude and frequency through pulse control, and can deal with various vibration forms.
