Title:
HAPTIC FEEDBACK SIGNAL GENERATION METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/055416
Kind Code:
A1
Abstract:
Provided in the present application are a haptic feedback signal generation method, an electronic device, and a storage medium. The haptic feedback signal generation method comprises: acquiring an initial haptic feedback signal; mapping the initial haptic feedback signal from a time domain to a frequency domain, so as to obtain an initial spectrogram of the initial haptic feedback signal in the frequency domain; adjusting the amplitude of a harmonic component of any frequency band in the initial spectrogram, so as to obtain a target spectrogram; and mapping, from the frequency domain to the time domain, a signal corresponding to the target spectrogram, so as to obtain a target haptic feedback signal. In the present application, a large number of haptic feedback signals with different haptic feedback effects can be acquired by means of adjusting the amplitude of a harmonic component of any frequency band in an initial spectrogram, such that the richness of the haptic feedback signals can be effectively improved.
