Abstract

The invention discloses a use method of a novel permanent magnet alternating current flat vibration motor, comprising a cylindrical shell with an opening at a lower end, and a rotor and a stator arranged inside the shell; the stator comprises a chassis arranged on the lower part of the shell, two coils arranged on the chassis, a rotating shaft arranged on the chassis and connected with the chassis, and a plurality of FPC wires arranged on the chassis. The rotor comprises a bracket arranged on a rotating shaft, magnet steel arranged on the bracket and connected with the bracket, an eccentric hammer arranged on one side of the bracket and connected with the bracket, and an oil bearing arranged on the rotating shaft. The two coils are electrically connected to the corresponding FPC wires. Theinvention has the characteristics of effectively prolonging the service life of the motor, reducing the noise and reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of micro-vibration motors, in particular to a novel permanent-magnet AC flat vibration motor that can effectively prolong the service life of the motor, reduce noise, and reduce production costs, and a use method thereof. Background technique [0002] Mobile phones are now an indispensable necessity in people's lives. As the functions of mobile phones become more and more powerful, people's lives are less and less mobile phones; at the same time, the quality of mobile phones is getting better and better. People change mobile phones due to mobile phone quality problems The frequency of mobile phones has dropped significantly, from the previous one needing to be replaced once a year, to now the mobile phone is replaced every few years; therefore, the life and quality requirements of the components in the mobile phone are also getting higher and higher. [0003] At present, the main vibration motors used in mob...
