Abstract:
A balanced armature driver, comprising a housing that is internally provided with a cavity, a diaphragm that divides the cavity into an upper cavity and a lower cavity, and a motor assembly that is fixed in the lower cavity. The housing comprises a lower housing, a middle frame and an upper housing. The diaphragm is clamped between the middle frame and the upper housing and divides the cavity into the upper cavity and the lower cavity. The motor assembly is fixed in the lower housing, the middle frame is sleeved outside of the motor assembly and is joined and fixed to the lower housing, and the motor assembly drives the diaphragm to vibrate up and down. In the balanced armature driver of the present application, the structure of a portion of the components is simplified, allowing the structural design to more easily achieve automatic assembly of the components, and manpower use is reduced.
