Method of generating vibration feedback signal, electronic device and storage medium

An electronic device comprising:

• a memory and at least one processor;
• and
• a vibration feedback device;
• wherein the memory is configured to store at least one program, causing when executed by the at least one processor, the at least one processor to implement a method of generating a target vibration feedback signal;
• wherein the vibration feedback device is configured to vibrate synchronously during audio playback in response to the target vibration feedback signal generated by the at least one processor;
• wherein the method of generating the target vibration feedback signal comprising:
• generating an energy change trend curve of audio based on audio data;
• wherein the energy change trend curve has a horizontal axis of frame number and a vertical axis of energy change value;
• comparing an energy change value in the energy change trend curve with a preset energy change threshold and obtaining a comparison result;
• dividing the audio into a plurality of audio segments based on the comparison result;
• wherein the comparison result indicates a tempo change trend corresponding to a respective audio segment of the plurality of audio segments;
• matching a vibration feedback signal to each of the plurality of audio segments based on the tempo change trend corresponding to the respective audio segment;
• performing a splicing process on all the vibration feedback signals to obtain the target vibration feedback signal.
