Abstract
The present disclosure provides a method for detecting a bandwidth of a linear vibration motor, including a linear vibration motor which comprises a housing and a motor vibrator. The method includes the following steps: step S: setting a target displacement level of the linear vibration motor; step S: measuring a displacement frequency response curve of the motor vibrator with reference to the target displacement level; step S: comparing the displacement frequency response curve obtained in step Swith a preset standard target displacement frequency response curve, determining whether the displacement frequency response curve is qualified, and if it is qualified, entering step S; step S: measuring a bandwidth of the linear vibration motor.
