摘要： The invention relates to a speaker diaphragm. The speaker diaphragm is composed of a dome portion located in the center and a circle of outer arc portion connected to the circumferential outer side of the dome portion. An outer diameter of the diaphragm is 38.9 mm to 39.95 mm. The dome portion has a dome height of 3.0 mm to 3.4 mm. The outer arc portion has an arc top height of 1.6 mm to 1.8 mm. An effective height between the dome portion and the outer arc portion is 0.8 mm to 1.0 mm. According to the speaker diaphragm of the invention, by increasing the effective height of the diaphragm and the dome height and by changing an outer arc shape and a pattern shape, the overall strength of the diaphragm is improved, the frequency peaks and valleys in a frequency response curve are reduced, and the high frequency is raised. In addition, a layer of PU damping material is also compounded between two different materials (PAR layer+PEEK layer) to increase the damping of the diaphragm.

摘要： A front cover for protecting a diaphragm of an earpiece is disclosed. A circular through hole is provided at the center of the front cover. A series of trapezoidal through holes surrounding the circular through hole are provided at fixed intervals encircling the circular through hole. The total area of the circular through hole and the trapezoidal through holes accounts for 40% to 55% of the area of the front cover. By verifying the effect of different shapes and different hole areas on a frequency response curve, and by designing a front cover according to the curvature and shape of a diaphragm and adjusting the hole areas to optimize the frequency response curve of an earpiece, the earpiece front cover enables expansion of the effective frequency bandwidth of an earpiece, smoothing out of the high frequency curve, and reducing acoustic peaks and valleys.
