Problems solved by technology

Since the existence of the annular spring rib 704 occupies the extension space of the cantilever 702, the utilization rate of the radial space of the cantilever 702 is low, the motor polarization tendency is large, and the vibration effect is poor

Abstract

The invention discloses a vibrating motor and portable equipment. The vibrating motor comprises a shell, a vibrating system and coils, wherein the shell comprises an upper cover and a lower shell which are mutually connected; a cavity is formed in the shell; the vibrating system is arranged in the cavity; the vibrating system comprises a vibrator and elastic sheets; magnetic gaps are formed in the vibrator; each elastic sheet is equipped with a fixed part and multiple cantilevers; a through hole is formed in the middle part of each fixed part; the cantilevers are formed by helically extending from the fixed parts along the center shaft direction of the fixed parts, and the cantilevers are gradually expanded; the fixed parts are fixedly connected with the vibrator; the tail ends of the cantilevers are fixedly connected with the shell; the coils are arranged in the cavity; and one ends of the coils are fixedly connected with the lower shell while the other ends of the coils are inserted into the magnetic gaps. The cantilevers of the elastic sheets of the vibrating motor are fixedly connected with the shell directly, so that the offset vibration of the vibrating motor is greatly lowered.

Description

technical field [0001] The present invention relates to the technical field of vibration equipment, and more particularly, to a flat linear vibration motor and a portable device using the vibration motor. Background technique [0002] The existing linear vibrating motor generally includes a casing, and a coil, a vibrator and shrapnel are arranged in the inner cavity of the casing. The coil and the shrapnel are arranged on opposite sides of the vibrator. One end of the coil is fixed on the housing, and the other end of the coil is inserted into the magnetic gap of the vibrator; one end of the shrapnel is fixedly connected with the vibrator, and the other end of the shrapnel is vibratingly connected with the housing. The side-by-side arrangement of the coil, the vibrator and the shrapnel takes up the vibration space and increases the volume of the linear vibration motor, which is not conducive to the miniaturization and thinning of the vibration motor. And, in the prior art ...
