摘要： A vibration noise processing method and apparatus, and a readable storage medium. The method includes: controlling a noise reduction component to collect vibration noise signal of a vibration component; generating a corresponding noise reduction control parameter according to signal characteristic index of the vibration noise signal; and controlling the noise reduction component to output corresponding reverse sound-wave signal. The reverse sound-wave signal has a frequency and an amplitude identical to the vibration noise signal and the reverse sound-wave signal has a phase opposite to the vibration noise signal. According to a vibration noise signal actually generated by the vibration component, the noise reduction component is controlled to output the corresponding reverse sound-wave signal to offset vibration noise in sound field, which prevents sound interference caused by vibration noise and meets vibration experience of the users, and thereby providing better auditory comfort experience for the users.

摘要： 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.

摘要： The present application provide a noise reduction method for a force feedback device, a gamepad, and a storage medium. The method includes: calculating a first time required for the vibrating rod to complete the first movement before the vibrating rod performs the first movement, and controlling the vibrating rod to stop the first movement to avoid collision with the first structure after the first time has elapsed since the vibrating rod is driven to start the first movement. Through the method, the noise generated while providing the vibration sensation for the player during the gamepad use can be reduced.
