Abstract
A haptic reproduction system comprises: a touch display device, an upper computer and a waveform generator. The touch display device comprises a piezoelectric unit, a touch display panel and a touch driving unit. The piezoelectric unit is disposed on the touch display panel. The touch driving unit is electrically connected to the touch display panel and the upper computer, and is configured to acquire touch information and transmit the touch information to the upper computer. The upper computer is electrically connected to the waveform generator, and is configured to send a first waveform generation instruction to the waveform generator according to the touch information. The waveform generator is configured to generate a first waveform signal according to the first waveform generation instruction. The piezoelectric unit is electrically connected to the waveform generator, and is configured to resonate with the touch display panel under the drive of the first waveform signal.
