Abstract

The present invention discloses a vibration motor and a portable device. The vibration motor comprises: a housing; a vibration system disposed in the cavity, and comprising a vibrator and an elastic sheet, the vibrator being provided with a magnetic gap and the elastic sheet having a fixing portion and a plurality of cantilevers, a through hole being arranged in a middle portion of the fixing portion, the cantilevers being formed by spirally extending the fixing portion along the central axis direction of the fixing portion, the cantilevers being gradually expanded, the fixing portion being fixedly connected with the vibrator, and the ends of the cantilevers being fixedly connected with the housing; and a coil arranged in the cavity, one end of the coil being fixedly connected with the lower housing, and the other end of the coil being inserted into the magnetic gap.

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 ...
