Abstract
The invention discloses a vibrating diaphragm used for enhancing a middle-frequency band output. The vibrating diaphragm comprises a vibrating diaphragm main body, a connecting portion, a vibrating diaphragm holder and a prestress force thin diaphragm. The prestress force thin diaphragm is tightly fixed on the vibrating diaphragm holder. One end of the vibrating diaphragm main body is connected with the vibrating diaphragm holder through the connecting portion. The vibrating diaphragm main body comprises an obverse face and a reverse face. The obverse face or the reverse face is tightly contacted with the prestress force thin diaphragm in a fit mode. The vibrating diaphragm main body is provided with a cavity body. The cavity is communicated with the obverse face and the reverse face. A partition is connected in the cavity body. The cavity body which is formed in the vibrating diaphragm can be with high-frequency resonance of a metal plate to producing low-frequency compensation so as to improve the phenomenon that the sound hearing feelings of the moving-iron unit are inclined to be cold. The partition which is additionally arranged in the cavity body can solve the problem that mechanical strength of the vibrating diaphragm is reduced because the cavity body is installed. The high-frequency loss of a sound unit can be decreased to obtain a middle-frequency band sound output. The invention further discloses a preparation method of the vibrating diaphragm.
