摘要： A linear vibration motor is disclosed. The linear vibration motor, includes a housing provided with an accommodation space; a vibrator accommodated in the accommodation space; and an electromagnet accommodated in the accommodation space. The vibrator includes a weight having a through-hole and a plurality of permanent magnets engaging with an inner wall of the through-hole. The electromagnet is located in the through-hole and separated from the permanent magnets. The electromagnet includes an iron core and a coil around the iron core for producing magnet fields interacting with the permanent magnets further for producing attracting and repelling force to drive the vibrator to vibrate.

摘要： A vibration motor includes a housing having a receiving space and a vibration unit. The vibration unit includes a main weight, a main pole plate, and a main magnet carried by the main pole plate. The main weight includes a first weight, and a second weight opposed to the first weight, the main magnet being sandwiched between the first and second weights, and two ends of the main pole plate respectively connected to the first weight and the second weight. The vibration unit further includes an auxiliary weight, an auxiliary pole plate, and an auxiliary magnet carried by the auxiliary pole plate. One of the main weight and the auxiliary weight forms a recess, and another forms a flange extending along a vibration direction corresponding to the recesses for engaging the main weight and the auxiliary weight.
