Abstract

The present disclosure relates to a sound generating device, a display device and a terminal. The sound generating device includes a first electrode layer, an insulating layer, an electromagnetic coil, and a magnetic diaphragm; the first electrode layer is disposed on the display substrate; the insulating layer is disposed on the The first electrode layer is far away from the side of the display substrate; the electromagnetic coil is arranged on the side of the insulating layer far away from the first electrode layer, and the projection of the electromagnetic coil on the display substrate is located at the non- In the opening area, the insulating layer is provided with a via hole, and the electromagnetic coil and the first electrode layer are connected through the via hole; the magnetic diaphragm is arranged on the side of the electromagnetic coil away from the insulating layer, and is used Vibrating and sounding in response to the magnetic field generated by the electromagnetic coil. Realize the internal sound of the screen, and solve the problem that due to the large package size of the exciter and the small space under the screen, it is difficult to arrange the exciter, and the position of the exciter is limited, so that the full-screen sound cannot be performed.

Description

technical field [0001] The present disclosure relates to the technical field of terminal sound generation, and in particular, to a sound generation device, a display device, and a terminal. Background technique [0002] In-screen sound generation technology refers to the conversion of audio electrical signals into mechanical vibration of the display screen through the sound exciter, and the sound waves are generated by the vibration to achieve the purpose of sound generation, so that the earpiece and the display screen are combined to meet the needs of the full screen of the terminal. [0003] At present, the in-screen sound is mainly provided by setting an exciter under the screen, and the exciter drives the screen to vibrate to produce sound. Due to the large package size of the exciter and the small space under the screen, it is difficult to arrange the exciter, and the position of the exciter is limited, so it is impossible to perform full-screen sound. [0004] It shou...
