Vibration exciter

Abstract

The invention discloses a vibration exciter which comprises a coil assembly and a magnetic circuit assembly. The coil assembly comprises a coil, an installation space is defined by the coil, the magnetic circuit assembly is located in the installation space, and the magnetic circuit assembly comprises a center washer, a magnetic insulation conductive frame and a magnet. The magnetic circuit assembly comprises a central washer and magnets, the magnets are arranged on the two sides of the central washer in the axial direction of the coil, the magnetic poles of the two faces, close to the central washer, of the magnets are the same, the magnetic insulation conductive frame is arranged on the outer side of the central washer in a sleeving mode, and a gap exists between the coil assembly and the magnetic circuit assembly. According to the technical scheme, high loudness can be obtained at a high frequency band, and the sounding effect is improved.

Description

technical field

[0001] The invention relates to the technical field of vibration motors, in particular to a vibration exciter. Background technique

[0002] The full screen of the mobile phone can realize the function of earpiece or speaker without opening. At present, the sound of the full screen is driven by the vibration of the electromagnetic effect of the exciter to drive the screen to vibrate, and the sound is completed through the vibration of the screen. However, the loudness of the high-frequency band using this sound generation method is low, resulting in poor sound effect in the high-frequency band. Contents of the invention

[0003] Based on this, in view of the existing method of using the vibration of the exciter to drive the sound of the screen, the loudness in the high frequency band is low, resulting in a poor sound effect, it is necessary to provide a vibration exciter, which is designed to be able to Get higher loudness and improve vocal production. ...
