摘要:
A vibration motor includes a fixed member, a vibration unit, and an elastic member. The fixed member includes a housing having a receiving space and a coil received in the receiving space and assembled with the housing. The vibration unit includes a first weight, a second weight, and a magnet sandwiched by the first and second weights. The motor further includes a positioning guiding member including a weight guiding rail formed on the weight, a base guiding rail formed on the bottom wall of the base, a movement rail formed cooperatively formed by the weight guiding rail and the base guiding rail, and a plurality of rolling members received in the movement rail for restricting the vibration unit to move along the movement rail. The weight guiding rail is formed on the weight by milling, and the base guiding rail is formed on the base by stamping.
