Haptic feedback module and device thereof with haptic feedback function
A haptic feedback module is applied to a haptic feedback operation of a device and includes a member to be vibrated, a vibration-transmitting plate, a vibration-transmitting point array, and a vibration component. The member to be vibrated is disposed on the device. The vibration-transmitting plate has an upper vibration-transmitting surface and a lower vibration-transmitting surface opposite to each other. The vibration-transmitting point array is disposed on the upper vibration-transmitting surface and contacts the member to be vibrated. The vibration component is disposed on one of the upper vibration-transmitting surface and the lower vibration-transmitting surface and coupled to the device. When the haptic feedback operation is performed, a vibration energy from the vibration component driven by the device passes through the vibration-transmitting plate and the vibration-transmitting point array sequentially to the member to be vibrated, for providing a haptic feedback to the device.
