Abstract

A flat brushless vibration motor include a housing, A substrate is fixedly arrange inside that shell, A connection shaft is fixedly arranged on the substrate, A magnet is sleeve on that connecting shaft, A metal rotate sleeve is arranged between that magnet and the connecting shaft, a plurality of magnetic members which attract or repel the magnet and the metal rotating sleeve after the magnet andthe metal rotating sleeve are energized are arranged around the connecting shaft on the substrate, and the magnetic poles of the adjacent magnetic members are opposite, the plurality of magnetic members are positioned between the substrate and the magnet correspondingly, and the vibration effect of the magnetic members is good.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a flat brushless vibration motor. Background technique [0002] At present, a flat vibration motor is usually installed in smart electronic products such as mobile phones or electronic wristbands to realize the vibration reminder function. Related literature (publication number CN 105429349 A) ​​discloses an existing flat vibrating motor, which mainly generates a magnetic field by energizing the coil, thereby driving the internal magnet to move up and down, thereby generating a vibration effect, but only by moving up and down In practical applications, the vibration effect is still weak, and there is room for improvement. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a flat brushless vibration motor with better vibration effect. [0004] In order to achieve the above object, the present invention provides a flat brushles...
