摘要:
A double resonance vibration motor includes a housing, vibration parts in the housing, a coil fixed in the housing, and elastic connectors to support elastically the vibration part. The vibration parts include a mass block, a first magnet group and a second magnet group installed in the mass block. The coil is opposite to the first magnetic group and the second magnetic group. The driving force generated by the first magnetic group and the coil makes the vibration motor vibrate along the first direction. The driving force of the second magnet group and the coil makes the vibration motor vibrate along the second direction. The first direction and the second direction intersect. Two different directions have respectively one resonance frequency. Two different resonant frequencies can vibrate alone or at the same time, to realize the control in different vibration directions.
