Abstract
This application provides a system for generating a drive signal and a method for generating a drive signal for driving a two-in-one device integrating a first component capable of generating sound and a second component capable of generating vibration. The system includes an audio signal pre-processing module, configured to perform low-frequency filtering and acoustic effect processing on an input signal according to a high-pass filtering parameter to obtain an audio signal; a vibration signal generation module, configured to generate a vibration signal based on an acoustic characteristic of the audio signal or a preset vibration library; a signal synthesis module, configured to superpose the audio signal with the vibration signal to output the drive signal; and an amplitude-limiting control module, configured to determine whether the audio signal and the vibration signal exceeds a maximum allowable range when superposed, and attenuate the audio signal and/or the vibration signal.
