Title:
METHOD AND APPARATUS FOR COMPENSATIG FOR LOW-FREQUENCY SENSE OF VIBRATION, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/097890
Kind Code:
A1
Abstract:
The present invention is applicable to the technical field of electronic devices. Provided are a method and apparatus for compensating for a low-frequency sense of vibration, and an electronic device. The method comprises: after a vibration apparatus receives a vibration instruction and before the vibration apparatus responds to the vibration instruction, acquiring an original vibration signal for driving the vibration apparatus to start vibration; providing a vibration starting compensation signal with a target period according to a peak period of the original vibration signal; and enabling the vibration apparatus to respond to the vibration instruction, driving the vibration apparatus by means of the vibration starting compensation signal, and adjusting a waveform peak value of the vibration starting compensation signal to cause a vibrator of the vibration apparatus to impact with a housing, wherein the impact between the vibrator of the vibration apparatus and the housing is used for compensating for a low-frequency sense of vibration of the vibration apparatus, and when the peak period of the original vibration signal is n, the target period of the vibration starting compensation signal is n × k, and the frequency of the impact between the vibrator of the vibration apparatus and the housing is 1/n × k. By means of the present invention, a sense of vibration generated by a vibration apparatus can be enhanced, thereby improving the tactile effect generated by the vibration apparatus under a low-frequency condition.
