In a light-transmitting vibration unit and the module thereof, which the vibration unit comprises a first and a second substrates stacked sequentially with each other, and made of a conductive polymer material, such that both first and second substrates have light transmittance and uniform resistance, and after a vibration driven component is electrically coupled to the first and second substrates, an electric field will be acted for converting electric energy into mechanical energy to produce vibrations. If the vibration unit is coupled directly to a touch-sensitive display unit, an image displayed by the touch-sensitive display unit will be able to pass through the vibration unit, and the vibrations produced by the vibration unit will be more directly transmitted to a touch object.
