一种振动系统、驱动方法及振动方向的转换方法
摘要：
本发明公开了一种振动系统、驱动方法及振动方向的转换方法。该振动系统包括驱动模块和平行设置的至少两个线性马达，所述驱动模块分别电连接并控制所有线性马达；第n个线性马达的固有频率为第一个线性马达的固有频率的n倍，第n个线性马达的谐振电流的初相与第n‑1个线性马达的谐振电流的初相相差π/2，其中，n≥2且为整数。该振动系统利用线性马达实现了非对称的单向振动，并且实现振动方向的转换。
摘要（英）：

The invention discloses a vibration system, a driving method and a conversion method of a vibration direction. The vibration system comprises a driving module and at least two parallelly arranged linear motors. The driving module is electrically connected and controls the linear motors. The fixed frequency of the nth linear motor is the n times of that of the first linear motor. The initial phase of the resonance current of the nth linear motor differs from the initial phase of the resonance current of the n-1th linear motor by pi/2, wherein n is an integer larger than or equal to 2. According to the invention, by use of the linearity, the nonsymmetrical unidirectional vibration is achieved and conversion of the vibration direction is achieved.
