Document Type and Number:
WIPO Patent Application WO/2023/093332
Kind Code:
A1
Abstract:
Disclosed in the present invention is a control method for a multidimensional vibration device. The method comprises: setting a changing curve of the voltage amplitude of each resonant frequency of each motor changing over time; constructing, on the basis of the resonant frequencies of each motor, a driving voltage family corresponding to the motor, the driving voltage family comprising a sine driving voltage family and/or a cosine driving voltage family; performing linear superposition on the driving voltage family of each motor, respectively, so as to obtain corresponding driving voltages; and on the basis of the driving voltages, driving each motor by a power amplifying circuit to generate corresponding vibration. By means of the control method for multidimensional vibration and the multidimensional vibration device corresponding to the control method provided in embodiments of the present application, the restoration of a vibration vector in the direction of any axis of a three-dimensional space can be realized, and multidimensional vibration feedback can be implemented by controlling changes in the vibration vector in real time, thereby improving the vibration experience.
