Abstract:
A magnetic balance guided linear vibration motor comprising a housing (1, 2), a vibrator, and a stator fixedly connected with the housing. The vibrator comprises a counterweight (31) and a vibrating block embedded and fixed in the counterweight, wherein a pair of first balancing magnets (61a, 61b) are respectively arranged on vertical sidewalls at two ends of the counterweight, second balancing magnets (62a, 62b) corresponding to the first balancing magnets are respectively arranged on the housing at positions corresponding to the two ends of the counterweight, and the second balancing magnets and the corresponding first balancing magnets are attracted to each other. The vibration motor provides the vibrator with vibration balance in a motor vibration space, overcomes the problem of wearing, deformation and balance error and the like due to motor mechanical balance means, and reduces motor noise, thus increasing the product quality and stability of the motor.
