Title:
LINEAR VIBRATING MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/267306
Kind Code:
A1
Abstract:
An embodiment of the present utility model discloses a linear vibrating motor, comprising a housing, a vibration assembly and stator assembly which are accommodated in the housing, and an elastic support member which supports the vibration assembly. The stator assembly comprises a coil, the axial direction of which in a horizontal plane is perpendicular to the vibration direction of the vibration assembly. The vibration assembly comprises: two mass blocks arranged along the vibration direction of the vibration assembly and two sets of magnetic circuit structures arranged along the axial direction of the coil. The vibration assembly comprises a vibration cavity, and the coil is located in the vibration cavity. The magnetic circuit structures comprise: a magnetic set and a magnetic conductive plate bound and fixed to the side of the magnetic set distant from the coil. The magnetic set is sandwiched and fixed between the two mass blocks. In the present utility model, the magnetic field strength of magnetic circuit structures can be effectively increased, thereby increasing the driving force of a motor structure and providing, for market products, more possibilities to select a linear vibrating motor having a large vibrating sensation within a limited space.
