It should be noted that, in the present application, the diaphragm 21 and the voice coil 23 in the diaphragm structure 2 are both disposed on the same side as the metal ring 22, for example, are disposed on the upper side of the metal ring 22 as shown in fig. 3, so that when the diaphragm structure 2 is disposed on the magnet, it is ensured that the bending direction of the diaphragm 21 of the diaphragm structure 2 (i.e., the bending direction of the cambered surface) faces the position of the phase plug 3, and the phase plug 3 is in contact connection with the concave surface of the diaphragm 21, that is, the bending direction of the diaphragm structure 2 in the present application is consistent with the compression direction of the front compression driving head, so that the influence on the sound wave transmission direction can be reduced in the transmission process of the sound wave emitted by the diaphragm structure 2, and the fidelity of the sound is improved.
The vibrating diaphragm structure 2 is mounted on the magnet 1 through the outer sliding wire 6, the diaphragm 21 is connected with the center post 5 through the inner sliding wire 7, and a certain gap is formed between the outer convex surface of the diaphragm 21 and the inner sliding wire 7.
