Abstract
An earphone comprising a transducer vibrating diaphragm structure is described herein. The transducer vibrating diaphragm structure comprises a diaphragm including a first surface and a second surface opposite the first surface, a first frame and a second frame disposed at two sides of the diaphragm and coupled to a periphery of the diaphragm, a first magnetic element and a second magnetic element disposed to correspond to the first surface and the second surface, respectively. A total area of the diaphragm is less than or equal to 120 square millimeters and a sensitivity of the diaphragm is greater than 105 dB.
