Abstract

The invention discloses a control method and device of a multi-dimensional stereo vibration device, computer equipment and a storage medium. The method comprises the following steps: setting a change curve of a voltage amplitude of each resonant frequency of each motor along with time; constructing a driving voltage family of the corresponding motor based on the resonant frequency of each motor, wherein the driving voltage family comprises a sine driving voltage family and/or a cosine driving voltage family; performing linear superposition on the driving voltage family of each motor to obtain corresponding driving voltage; and driving each motor to generate corresponding vibration through a power amplification circuit based on the driving voltage. According to the multi-dimensional three-dimensional vibration control method and the multi-dimensional three-dimensional vibration device corresponding to the control method provided by the embodiment of the invention, the reduction of the vibration vector in any axial direction in the three-dimensional space can be realized, and the multi-dimensional three-dimensional vibration feedback can be realized by controlling the change of the vibration vector in real time, so that the vibration experience is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a control method and a control device for a multi-dimensional three-dimensional vibration device. Background technique [0002] Linear Resonant Actuator (LRA) has been widely used in various vibration occasions of consumer electronics, especially games and AR / VR products, due to its advantages of strong vibration, richness, crispness, and low energy consumption. [0003] The richness of vibration in a single direction and a single frequency is limited, which can no longer meet the vibration needs of current consumer products. Compared with single-axis vibration, multi-dimensional vibration can provide a richer and more realistic tactile experience, and has a very good application prospect in games, AR / VR and other fields. [0004] However, currently there is no device capable of providing multi-dimensional vibration and its related control method in the market. Therefore, the ...
