Abstract

The invention provides a display device which comprises a display panel, a back plate, a frame and an exciter, the exciter is located in the frame, and the exciter comprises a shell, a coil, a magnet, a magnetostrictive part and a vibration part; wherein the shell is connected with the frame or the back plate, the shell surrounds the coil, the coil is used for generating an alternating magnetic field according to a control signal, the coil is annular, the magnet and the magnetostriction piece are both located in the coil and are arranged in the axial direction of the coil, one end of the vibration piece is located in the shell, and the other end of the vibration piece extends out of the shell. The vibrating piece, the magnet and the magnetostrictive piece are tightly pressed between the frame and the shell; and the magnetostriction piece can generate telescopic deformation along the axial direction of the coil in a superposed magnetic field of the alternating magnetic field and the magnetic field generated by the magnet, and drives the frame to vibrate and produce sound. The display device provided by the invention is small in thickness and conforms to the ultrathin development trend of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the development of modern work, display devices such as mobile phones, tablet computers, and liquid crystal displays are widely used in various aspects of people's production and life.
