Abstract

The invention provides a vibrating motor, which comprises a housing, a stator arranged in the housing, a rotor capable of moving relative to the stator, third magnetic steel and fourth magnetic steel,wherein the rotor comprises first magnetic steel and second magnetic steel, which are arranged side by side along the movement direction of the rotor; the stator comprises a coil which winds two adjacent ends of the first magnetic steel and the second magnetic steel; the third magnetic steel and the fourth magnetic steel are arranged on two opposite inner wall surfaces of the housing separately,are opposite to two opposite ends of the first magnetic steel and the second magnetic steel and are arranged at an interval; and the third magnetic steel and the fourth magnetic steel provide the rotor with the elastic return force of reciprocating motion. When the coil is electrified, the first magnetic steel and the second magnetic steel move along the axial direction of the coil and rebound toform the motion of striking back and forth after striking the third magnetic steel or the fourth magnetic steel; and the third magnetic steel or the fourth magnetic steel can be very thin and the elastic rigidity is relatively low, so that a low resonance frequency f0 can be achieved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of motors, in particular to vibration motors. [0003] 【Background technique】 [0004] The tactile feedback vibration motor of the game handle in the prior art uses a mechanical shrapnel structure as an elastic and supporting component. The existing mechanical shrapnel structure needs to obtain a low resonance frequency f0, and to achieve a large vibration amount, the vibration displacement must be large. The mechanical shrapnel structure is in There are reliability problems under large displacement. It is difficult to simultaneously achieve a lower resonance frequency f0, the stiffness of the supporting vibrator and good reliability under a large stroke. [0005] Therefore, it is necessary to provide a method to achieve a lower resonance frequency f0, the stiffness of the supporting vibrator and good reliability under a large stroke. [0006] 【Content of invention】 [0007] The purpose of the present inven...
