Title: LINEAR VIBRATION MOTOR
Abstract:
A linear vibration motor, comprising a housing, a stator, a vibrator, and an elastic support member (1). The vibrator comprises a mass block (2) and a magnet (3). The stator comprises coils and circuit boards. The coils comprise a first coil (4) and a second coil (5). The circuit boards comprise a first coil fixing board (6) and a second coil fixing board (7). The first coil and the second coil are respectively located on two opposite sides of the mass block. The first coil is connected with the first coil fixing board. The second coil is connected with the second coil fixing board. The first coil fixing board is fixed on a first washer board (8). The second coil fixing board is fixed on a second washer board (9). The first washer board and the second washer board are respectively fixed on the motor housing. The vibration motor can reduce the loss of a magnetic field and improve the utilization rate of the magnetic field while implementing vibration feedback on a touch operation of a user.
