The embodiment of the invention discloses a signal calibration method, and the method comprises the steps: obtaining a first frequency corresponding to a to-be-processed signal, and obtaining the resonant frequency of a motor as a second frequency; under the condition that the first frequency and the second frequency are inconsistent, determining sampling coordinate indexes corresponding to a plurality of sampling points according to the first frequency and the second frequency; performing preset processing on the sampling coordinate index to obtain an integer coordinate index and a decimal coordinate index corresponding to the sampling coordinate index; and processing the to-be-processed signal according to the integer coordinate index and the decimal coordinate index to generate a targetcalibration signal, and outputting the target calibration signal. By adopting the signal calibration method provided by the invention, the vibration effect difference caused by the performance or parameter difference of different motor monomers can be reduced, the consistency of the vibration effect corresponding to the excitation signal is improved, and the user experience is improved. In addition, the invention also provides a signal calibration device, equipment and a storage medium.
Description
technical field [0001] The present invention relates to the technical field of signal processing, in particular to a signal calibration method, device, equipment and storage medium. Background technique [0002] Haptic feedback technology is to make the user feel the tactile changes by changing the force, vibration and other ways. Haptic feedback technology can be applied to assist creation and control of virtual scenes or virtual objects of smartphones, tablet computers, and the like. Among them, loading a specific excitation signal to an actuator (ie, a motor) to make it output a specific vibration effect is a major implementation of tactile feedback. [0003] Usually, the excitation signal of the motor is only for a specific motor frequency, so that it outputs a specific vibration effect. In actual application scenarios, due to the differences between different motor units, such as the obvious difference in resonance frequency, the excitation signal will not match the m...
