ACTUATOR VIBRATION CONTROL METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2023/109274

A1

An actuator vibration control method and apparatus, and a computer device and a storage medium. The method comprises: acquiring an audio signal and feature data of an actuator, wherein the audio signal is an audio signal for driving the actuator, and the feature data comprises a bandwidth of a frequency sweeping characteristic of the actuator and a sound-production frequency band of the actuator; on the basis of the feature data, performing low-pass filtering and high-pass filtering on the audio signal, so as to obtain a preliminary acceleration; enhancing the amplitude of the preliminary acceleration, so as to obtain a target acceleration; on the basis of the target acceleration, determining a driving voltage corresponding to the target acceleration; and performing power amplification on the driving voltage, so as to drive the actuator to generate vibration sensing feedback. By means of the method, the vibration sensing experience of broadband vibration can be enhanced, and the technical problem of actuator sound production is also avoided.
