BROADBAND VIBRATION DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/109275
Kind Code:
A1
Abstract:
The present application provides a broadband vibration device and a control method therefor. The method comprises: obtaining frequency characteristics of a broadband vibration device, a pulse vibration waveform digital sequence, a target broadband signal, and target information; setting a first resonant frequency band of the broadband vibration device as a broadband, and a resonant frequency point of a second resonant frequency band of the broadband vibration device as a pulse frequency point according to the frequency characteristic of the broadband vibration device; generating a broadband vibration signal according to the target broadband signal and the broadband; constructing, according to the pulse vibration waveform digital sequence and the pulse frequency point, a pulse vibration waveform library corresponding to the pulse vibration waveform digital sequence; selecting a pulse vibration waveform corresponding to the target information from the pulse vibration waveform library to generate a pulse vibration signal; and driving the broadband vibration device according to the broadband vibration signal and the pulse vibration signal. Compared with the prior art, rich broadband vibration feedback and strong and clear pulse vibration experience can be realized at the same time.
