Document Type and Number:
WIPO Patent Application WO/2023/071642
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of linear resonant actuators. Disclosed are a method for controlling a linear resonant actuator, and a device and a medium. The method comprises: acquiring driving waveform data; on the basis of a preset frame duration, dividing the driving waveform data into at least one frame of driving waveform sub-data; on the basis of a hardware parameter, predicting at least one frame of vibration parameter waveform of a linear resonant actuator which is driven according to at least one frame of driving waveform data; determining an intra-frame vibration parameter peak value of each frame of vibration parameter waveform; for each frame of vibration parameter waveform, if the intra-frame vibration parameter peak value is greater than a hardware characteristic parameter peak value, decreasing all vibration parameter values of the vibration parameter waveform, so as to make the intra-frame vibration parameter peak value less than or equal to the hardware characteristic parameter peak value, and obtaining at least one frame of adjusted vibration parameter waveform; and on the basis of the at least one frame of adjusted vibration parameter waveform, controlling the linear resonant actuator to vibrate. By means of the present invention, the situation of a vibration parameter exceeding a hardware characteristic parameter peak value which is allowed by hardware of a linear resonant actuator can be avoided.
