Abstract

The present invention relates to the technical field of electronic products, and provides a linear vibration motor. The linear vibration motor comprises a motor housing, a stator, a vibrator, and two elastic supports for suspending the vibrator within the motor housing, for supporting the vibrator and for providing elastic restoring forces, wherein the elastic supports are located at two ends of the vibrator in a vibration direction respectively. Each of the elastic supports is made up of a plurality of elastic sheets whose one ends are fixedly connected in sequence, which are arranged side by side and which have C-shaped openings respectively. Each of the elastic supports comprises a first connection point fixedly connected to the vibrator and a second connection point fixedly connected to the inner wall of the motor housing. Therefore, the polarization phenomenon of a vibration block is reduced when the vibration feedback to a user's touch operation is realized, the noise is reduced, and the stability and the reliability of the entire linear vibration 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 to design, its shap...
