Abstract
The present disclosure provides a linear motor having a housing with an accommodation space; a vibrator accommodated in the accommodation space; and a first stator locating opposite to the vibrator and fixed to the housing. The first stator includes a first circuit board opposite to the vibrator, a first coil on a the side of the first circuit board close to the vibrator, and a first magnetic conductive sheet locating on a side of the first circuit board away from the vibrator. The linear motor further has a spring bracket supporting the vibrator in the accommodation space. The present invention is to provide a linear motor which improves the space utilization of the linear motor in a thickness direction.
