Abstract

The invention discloses a linear vibration motor and electronic equipment. The motor includes: a magnet; a mover, including a permanent magnet; and a linear movement support body, wherein the mover is installed on the linear movement support body to move along a linear movement path defined by the linear movement support body, Wherein, the magnetic conductor is disposed near the mover along the direction of the linear movement path to interact with the permanent magnet, so that the mover tends to balance the linear movement path in the non-excited state. location, and the material of the magnetic conductor is a soft magnetic material. According to one embodiment, the mechanical spring can be omitted.

Description

technical field [0001] The present invention relates to the technical field of motors, and more particularly, to a linear vibration motor and electronic equipment. Background technique [0002] Currently, more and more electronic devices use vibration motors. For example, portable consumer electronic devices such as mobile phones, wearable devices, game consoles, etc. can employ vibration motors as feedback to the system. For example, a vibration motor can be used as a vibration reminder for a mobile phone, or a vibration motor can be used to provide a gaming touch for a game machine, etc. [0003] Compared with the traditional eccentric wheel type rotary vibration motor, the linear vibration motor has many advantages. For example, a linear vibration motor does not require a commutator and brushes, and it does not generate frictional sparks during operation. The linear vibrating motor operates reliably and responds quickly. Therefore, the application of linear vibration ...
