Elastic component for resonant motor and resonant motor

Abstract

This invention discloses an elastic component used for a resonant motor, and a resonant motor. The elastic component used for the resonant motor is integrated, and is used for making the resonant motor generate vibration and carrying a magnetic material; a coil fixed on a lower shell, an elastic component and the magnetic material in the coil are arranged in a space enclosed by an upper shell and a lower shell of the resonant motor; wherein the elastic component comprises a main body for carrying the magnetic material, and elastic structures arranged at two sides of the main body so as to be connected on the upper shell or the lower shell; the main body and the elastic structures at the two ends are integrated. The resonant motor has simple structure, low assembling difficulty, less accessories, less assembling steps, light weight, small thickness, high reliability, less energy consumption, better vibration effect and low cost, and saves production hours and materials.

Description

technical field [0001] The invention relates to the field of micro-motors, in particular to an elastic component for a resonant motor and the resonant motor. Background technique [0002] The resonant motor is a micro-motor that vibrates in the horizontal direction, and is mostly used in portable electronic products, such as mobile phones, handheld game consoles and handheld multimedia entertainment equipment. With the continuous development of portable electronic products in the direction of thinner and smaller, resonant motors are also gradually developing in a flat and narrow structure. [0003] At present, the resonant motors on the market are designed with two shrapnel or two springs, and the connection of the magnet is unstable when it is working. Therefore, a bracket for fixing the magnet is needed, and the two elastic parts are connected with the bracket. High, poor reliability, and the mass of the overall movable components is heavy, resulting in poor reliability a...

AI Technical Summary

Problems solved by technology

The vibrator (permanent magnet and mass block) of the flat linear motor is heavy, resulting in poor vibration reliability and high power consumption of the linear motor; and due to the existence of the mass block, the linear motor cannot develop in a thinner direction; its coil is located in Under the permanent magnet, only half of the magnetic field generated by the coil is used, wasting electric energy
