Abstract
A method of generating a vibration feedback signal is provided and includes: generating an energy change trend curve (with a frame number as a horizontal axis and an energy change value as a vertical axis) of audio based on audio data; comparing an energy change value in the energy change trend curve with a preset energy change threshold; dividing the audio into audio segments based on a comparison result (indicating a tempo change trend of audio); matching a vibration feedback signal to the respective audio segment based on the tempo change trend; performing splicing process on all vibration feedback signals to obtain a target vibration feedback signal. The target vibration feedback signal obtained by splicing the vibration feedback signals finally matched to the audio segments conforms to the overall tempo change trend of the audio, thus effectively improving the rationality on matching between the audio and the vibration feedback signal.
