Abstract
A method and circuit for acquiring an output quantity of a linear resonance actuator are disclosed. The method comprises the steps of: establishing a circuit that simulates the linear resonance actuator by using passive electrical devices according to an electrical parameter and a kinematic parameter of the linear resonance actuator, the passive electrical devices comprise at least a resistor, a capacitor and an inductor; selecting a measuring point in the circuit according to an output quantity that the linear resonance actuator needs; and inputting a driving signal of an input source to an input end of the circuit, and collecting an electrical signal that is outputted at the measuring point to obtain the output quantity of the simulated linear resonance actuator. According to the technical solution of the application, a circuit module or system model that simulates the linear resonance actuator is established and used in the process of developing and debugging of projects, to replace the technical solutions that directly use physical actuators, thereby improving the efficiency and avoiding the relying on physical actuators.
