Abstract

The invention relates to the technical field of electronic products and provides a linear vibrating motor. The linear vibrating motor comprises a motor shell, a stator, an oscillator and two elastic supporting elements which make the oscillator suspended in the motor shell and are used for supporting the oscillator and providing elastic restoring force. The two elastic supporting elements are located at the two ends of the vibrating direction of the oscillator respectively. Each elastic supporting element comprises a plurality of elastic pieces distributed side by side and sequentially and fixedly connected end to end. Elastic arms of the elastic pieces are of a Z-type structure. Each elastic supporting element comprises a first connection point fixedly connected with the oscillator and a second connection point fixedly connected with the inner wall of the motor shell. The polarization phenomenon of a vibrating block in the vibrating process is reduced while vibration feedback of user touch operation is achieved, noise is lowered, and stability and reliability of the whole linear vibrating motor are improved.

Description

technical field [0001] The invention belongs to the technical field of electronic products, in particular to a linear vibration motor. Background technique [0002] At present, portable consumer electronic products are developing rapidly, and consumers are increasingly favoring electronic products that are thinner and lighter and have better tactile experience. Linear vibrating motors are generally used as actuators for haptic experience, and play the role of system vibration feedback. The development direction of better and thinner electronic products determines that the elastic support must also be improved in the direction of flattening the size. [0003] Most of the linear vibration motors realize the overall vibration through elastic supports. The elastic supports are more common in the form of springs or shrapnel. The elastic supports in the form of springs or shrapnel are mainly based on the internal vibration of the linear vibration motor. Space design, its shape a...
