Abstract

The invention discloses a one-way vibration system, device and method based on linear motors. The system comprises the multiple linear motors, a control chip and driving circuits, wherein the resonant frequencies between any two linear motors differ in integral multiple, the control chip is used for outputting driving signals corresponding to the linear motors one to one according to a first user instruction, the frequency of each driving signal is within the preset range by adopting the resonant frequency of the corresponding linear motor as the reference, and any two driving signals have phase angles with adjustable phases; the driving circuits correspond to the linear motors one to one and are used for driving and amplifying the driving signals, and sending the driven and amplified driving signals to the corresponding linear motors so as to control the corresponding linear motors, and then the one-way vibration effect is obtained. It is thus clear that the vibration effects of the multiple linear motors can be equivalent to one-way vibration after being synthesized, and the application range is enlarged.

Description

Technical field [0001] The present invention relates to the technical field of motor vibration, in particular to a one-way one-way vibration system, device and method based on a linear motor. Background technique [0002] Linear motors are used in many fields, please refer to figure 1 , figure 1 It is a schematic diagram of the linear motor structure. The linear motor includes a yoke for connecting magnets of the same nature, an elastic sheet for generating a restoring force due to the compression of the vibrator when the vibrator moves to both ends, and a magnet for moving under the action of the magnetic field of the coil , It is used to generate a magnetic field with a change of direction after the alternating current is applied to drive the coil of the magnet to move and the shell for protection and shielding. When the alternating current is passed through the coil, due to the change of the current polarity, the coil will produce a magnetic field with a direction change. The ...
