Embodiment 1

[0034] A method for calibrating a vibration signal proposed in this embodiment, the vibration signal is used to drive a calibration motor to vibrate, please refer to figure 1 , the adjustment method of the vibration signal includes:

[0035] S1. Determine a mapping relationship between a vibration effect parameter of a preset motor and a calibration parameter of a preset motor.

[0036] Specifically, the mapping relationship between the vibration effect parameters and the calibration parameters needs to be determined before subsequent calibration operations can be performed. Each parameter in the above step S1 is explained as follows:

[0037] The preset motor is a virtual motor model, which can be used to simulate an actual motor in some scenarios.

[0038] The vibration effect parameter is a parameter that reflects the vibration effect of the motor. More specifically, the vibration effect parameter is a parameter reflecting the vibration braking effect of the motor.

Abstract

The invention provides a vibration signal calibration method, a storage medium and electronic equipment. The vibration signal calibration method comprises the following steps: firstly, determining a mapping relationship between a vibration effect parameter of a calibration motor and a calibration parameter thereof (the calibration parameter is a parameter reflecting a relationship between a structure parameter of the motor and a vibration displacement of the motor), so that after the initial vibration signal X drives the calibration motor, the detection value of the calibration parameter is obtained; and judging whether the value of the vibration effect parameter corresponding to the negative value of the detection value is superior to the value of the vibration effect parameter corresponding to the detection value in the mapping relation, if so, setting the initial vibration signal to be -X, and if not, setting the initial vibration signal to be X, thus enhancing tactile feedback of the calibration motor. Thus, in the batch use process of the motor, each motor monomer can carry out adaptive calibration on the vibration signal according to the structural parameters of the motor monomer, and the consistency of vibration feedback in the batch use process of the motor is improved, and tactile feedback is enhanced.

Description

【Technical field】 [0001] The invention relates to the technical field of linear motors, in particular to a vibration signal calibration method, storage medium and electronic equipment. 【Background technique】 [0002] In the application of electronic devices (smartphones or tablet computers, etc.), motors are playing an increasingly important role as tactile feedback. At present, in the production process of the motor, due to the influence of the magnetic circuit, structure, process and assembly, the motor will show a certain asymmetry. The specific performance is that the structural parameters of the motor will show asymmetry. More specifically It is manifested that the electromagnetic force, spring force, etc. are not symmetrical about the center point of the motor in terms of physical displacement. [0003] At present, in the mass use of motors, all motors are usually driven by fixed signals. It is unrealistic to design a dedicated signal for each motor unit to generate t...
