Problems solved by technology

[0003] In order to increase the vibration intensity, the existing method is to set a relatively large gain based on experience to increase the voltage of the output signal. However, since the vibration amplitude of the linear motor cannot be identified and controlled by the vibration system, once the amplitude exceeds a certain amplitude, it will be It will cause serious damage to the linear motor. Therefore, based on the existing control method, it is difficult to set up empirically to ensure the safety of the linear motor and output the highest vibration intensity as possible.

Abstract

The invention discloses a method, a device and a system for actively controlling linear motor vibration, and electronic device. The method comprises the steps: an input signal for driving a linear motor or a signal generated according to the input signal is acquired for serving as a to-be-processed signal; the frequency and the voltage of the to-be-processed signal are analyzed; according to data for reflecting output voltage, vibration frequency and maximum safe amplitude correspondence, the output voltage for making the analyzed frequency to reach the maximum safe amplitude serves as maximum safe output voltage; according to the maximum safe output voltage and the amplification times of a power amplifier, maximum safe input voltage can be obtained through calculation; an adjusting instruction containing a ratio of the maximum safe input voltage to analyzed voltage is transmitted to a pre-filtering amplifier, and the adjustment of gain is performed; the adjusting instruction containing the maximum safe input voltage is outputted to a compressor and/or limiter, and the parameter adjustment is performed. According to the invention, the maximum vibration strength can be outputted under a premise of ensuring the safety of the linear motor.

Description

technical field [0001] The present invention relates to the technical field of linear motor vibration control, and more specifically, the present invention relates to a method, device, system and electronic equipment for actively controlling the vibration of a linear motor. Background technique [0002] With the development of mobile internet technology and the influx of various consumer electronics products, people's life has become intelligent and diversified. In the colorful entertainment life, people have higher and higher requirements for the experience of entertainment products, and people need richer body perception and human-computer interaction experience. The sense of touch occupies a relatively important part in the interactive application of somatosensory, and the linear motor is the key device that reflects the sense of touch (or vibration). Therefore, electronic devices such as smart phones, tablet computers, smart watches, smart glasses, smart bracelets, game...
