Electromagnetic driving mechanism for fatigue detection and tester

The invention discloses an electromagnetic driving mechanism and a tester for fatigue detection, wherein the electromagnetic driving mechanism comprises a magnetic circuit structure which provides a DC magnetic field; a framework which sleeves the magnetic core; double coils which are wound outside the framework and are stressed in a magnetic field to drive the framework to do axial reciprocating motion when alternating current is loaded on the double coils; and a connecting piece which is axially fixed on the framework, so that the connecting piece and the framework synchronously perform axial reciprocating motion. According to the invention, the vibration working state of the electroacoustic component can be simulated, and driving power is provided for anti-fatigue detection of the electroacoustic component. 本发明公开了一种用于疲劳检测的电磁驱动机构及测试仪，其中电磁驱动机构包括磁路结构，提供直流磁场；套设在所述磁芯外的骨架；绕制在所述骨架外的双线圈，用于在所述双线圈加载交流电流时在磁场中受力带动所述骨架进行轴向往复移动；轴向固定在所述骨架上的连接件，使所述连接件与所述骨架同步进行轴向往复移动。本发明可模拟电声部件的振动工作状态，为电声部件的抗疲劳检测提供驱动动力。
