【Embodiment】
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of acoustical generator 1 that the application preferred embodiment provides includes vibrational system 10, magnetic circuit system
System 20, the frame 30 for housing vibrational system and magnetic circuit system and the pad side 40 being set up in frame 30.
As shown in Fig. 2 magnetic circuit system 20, including lower plate 21, the folded main magnet steel 22 for being located at the center position of lower plate 21,
The folded secondary magnet steel 24 being located at the marginal position of lower plate 21, the folded main pole core 23 for being located at the main upper surface of magnet steel 22, folded it is located at secondary magnetic
The consequent pole core 25 of the upper surface of steel 24.Secondary magnet steel 24 is arranged to surround main magnet steel 22 and spaced apart to be formed with main magnet steel 22
Magnetic gap 26.
As shown in figure 3, the voice coil loudspeaker voice coil 12 that vibrational system 10 includes vibrating diaphragm 11 and drives vibrating diaphragm 11 to vibrate.Vibrating diaphragm 11 includes being located at
The top dome portion 111 of center, from the ring portion 112 of the edge outward bending extension of top dome portion 111 and from the end of ring portion 112
