Abstract: Provided is an input device. The input device includes a piezoelectric vibration member; a frame disposed to contact at least one area of the piezoelectric vibration member; and a connection member disposed on one surface of the piezoelectric vibration member. The piezoelectric vibration member detects a pressure applied from the outside to generate a voltage and is vibrated in accordance with a signal applied from an external device.

Abstract: Disclosed is a touch screen apparatus including a frame, a touch screen panel provided inside the frame, and a piezoelectric vibration member provided between the frame and the touch screen panel, wherein the piezoelectric vibration member vibrates in a horizontal direction of the touch screen.

Abstract: Provided is a complex device including: a frame in which a predetermined space is provided; a vibration member provided in the frame and generating vibration; and a speaker provided in the frame and generating a sound.

Abstract: Provided is a piezoelectric vibrating module including a case provided therein with a predetermined space, a piezoelectric vibrating member provided in the case, vibrating according to an applied voltage, and including a piezoelectric element; a weight member provided in the case and provided to be in contact with a portion of the piezoelectric vibrating member; and at least one fixing member provided in one region of the piezoelectric vibrating member to contact and fix the weight member.
