Problems solved by technology

The shrapnel is prone to breakage during the vibration process, resulting in the failure of the linear vibration motor
[0004] In addition, the existence of the shrapnel makes the assembly of the existing linear vibration motor difficult, the BOM cost is high, and the manufacturing process is complicated
[0005] In addition, the drive mode of the existing linear vibration motor is AC drive
This method is not convenient for direct application of terminals such as mobile phones

Abstract

The invention discloses a linear vibration motor. The linear vibration motor comprises a stator assembly and an oscillator assembly, wherein the stator assembly and the oscillator assembly are connected in a sliding way so that the oscillator slides along a setting direction, the stator assembly comprises a plurality of coils, the plurality of coils are sequentially arranged along a sliding direction and are separated from the oscillator, the oscillator assembly comprises a plurality of magnetic poles, the magnetic poles are in one-to-one correspondence to the coils, the polarity of each coilduring DC current passing is opposite to the polarity of the magnetic pole corresponding to the coil, the distance between two arbitrary magnetic poles is smaller than the distance between two coils corresponding to the two magnetic poles, the two coils are alternatively energized and de-energized, so that the two magnetic poles are alternatively absorbed by the respective and corresponding coils,and the oscillator assembly vibrates.

Description

technical field [0001] The present invention relates to the technical field of vibration devices, and more particularly, to a linear vibration motor. Background technique [0002] Existing linear vibration motors generally include a housing, a vibrator assembly, a stator assembly and shrapnel. The vibrator assembly, the stator assembly and the shrapnel are arranged in the casing. One end of the shrapnel is fixed on the shell. The vibrator assembly is suspended in the shell through the shrapnel. The vibrator assembly includes a magnet and a counterweight, which are fixed together. The stator assembly includes coils. The coil passes through an alternating current, interacts with the magnet to generate an Ampere force, and the two vibrate. Shrapnel provides elastic recovery. [0003] The existing linear vibration motor is provided with shrapnel. The shrapnel is prone to fracture during the vibration process, resulting in failure of the linear vibration motor. [0004] I...
