The invention discloses an electromagnetic exciter, which comprises an electromagnetic coil (100), a first magnet (200) and an exciter casing (300), and the electromagnetic coil (100) and the first magnet (200) are arranged on the exciter casing (300) ), the first magnet (200) is arranged on the first side of the electromagnetic coil (100), the first magnetic pole of the first magnet (200) and the second magnetic pole of the first magnet (200) are located in the first magnet (200) on the same side, and both face the electromagnetic coil (100), the first magnet (200) is connected with the exciter housing (300), and the exciter housing (300) is connected with the display screen, when the electromagnetic coil (100) is energized , the first magnet (200) can drive the exciter casing (300) to drive the display screen to reciprocate and vibrate in a direction perpendicular to the display screen. The solution can solve the problem that the electromagnetic exciter in the current electronic equipment will cause relatively serious magnetic interference to other devices in the electronic equipment. The invention discloses an electronic device.
Description
technical field [0001] The invention relates to the technical field of communication equipment, in particular to an electromagnetic exciter and electronic equipment. Background technique [0002] With the advancement of science and technology, the performance of electronic equipment continues to be optimized, among which the more prominent performance is: the screen-to-body ratio of electronic equipment is getting larger and larger. In order to further increase the screen-to-body ratio of the electronic device, the display screen of the electronic device should not open holes as much as possible. In order to realize no opening of the display screen, more and more electronic devices adopt screen sound technology. [0003] In the related technology, an electromagnetic exciter is arranged inside the display screen of the electronic device, and the electromagnetic exciter drives the display screen to vibrate during the working process, thereby realizing sound generation of the ...
