Abstract
Provided are a method for generating a haptic feedback signal, an electronic device, and a storage medium. The method includes: acquiring an initial haptic feedback signal; mapping an initial haptic feedback signal from a time domain to a frequency domain to obtain an initial spectrogram of the initial haptic feedback signal in the frequency domain; adjusting an amplitude value of a harmonic component of any frequency band in the initial spectrogram to obtain a target spectrogram; and mapping a signal corresponding to the target spectrogram from the frequency domain to the time domain to obtain a target haptic feedback signal. In the present application, a large number of haptic feedback signals with different haptic feedback effects may be obtained by adjusting the amplitude value of the harmonic component of any frequency band in the initial spectrogram, thereby effectively improving the richness of the haptic feedback signals.
