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 motor cannot be identified and controlled by the vibration system, once the amplitude exceeds a certain amplitude, it will be Cause serious damage to the motor, therefore, based on the existing control method, it is difficult to set by experience to ensure the safety of the motor and output the highest vibration intensity as possible

Abstract

The invention discloses a method, device and system for actively controlling vibration of a linear motor and electronic equipment. The method comprises the following steps of acquiring an input signal for driving the linear motor; capturing the input signal within a set time as a signal to be analyzed; analyzing frequency points to be processed of the signal to be analyzed within a set frequency range and a voltage corresponding to each frequency point to be processed; obtaining an amplitude under a reference voltage corresponding to each frequency point to be processed according to a displacement model of a corresponding relation between the known reflection frequency and the amplitude under the reference voltage; calculating to obtain that the sum of the amplitude corresponding to each frequency point to be processed does not exceed a voltage amplification factor of maximum safety amplitude according to the maximum safety amplitude of the linear motor, the voltage corresponding to each frequency point to be processed and the amplitude under the reference voltage; sending an adjustment instruction comprising the voltage amplification factor to an amplifier for gain adjustment. Therefore, the highest vibration strength can be output possibly on the premise that the motor safety can be ensured.

Description

technical field [0001] The present invention relates to the field of motor vibration control, 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 popularization of smart devices and the development of virtual reality technology, various consumer electronic products appear in people's daily life. Smartphones, tablet computers, virtual reality devices and other products give people better and better experiences. Vibration feedback occupies a relatively important part in this type of electronic products, and linear motors are the key components that reflect vibration feedback. Basically all smart devices (smartphones, tablets, smart watches, smart glasses, smart bracelets) and gaming devices (gamepads) and virtual reality devices are equipped with linear motor devices to provide vibratory feedback. [0003] In order to increase the...
