Dynamic system 13.
Described frame 11 is used for holding described magnetic circuit system 12 and described vibrational system 13.
The most as Figure 1-3, described magnetic circuit system 12 includes the yoke 121 being fixed in described frame 11, assembles
In described yoke 121 main magnet steel 122, be attached at the main pole core 123 on described main magnet steel 122 surface, assemble in described yoke 121
And lay respectively at the secondary magnet steel 124 of described main magnet steel 122 both sides and be attached at the consequent pole core 125 on described secondary magnet steel 124 surface.Institute
The quantity stating secondary magnet steel 124 and described consequent pole core 125 is two, and each described consequent pole core 125 is attached at described in one
On secondary magnet steel 124.Wherein, secondary magnet steel 124 and main magnet steel 122 interval arrange and form what the voice coil loudspeaker voice coil 132 for vibrational system 13 inserted
Magnetic gap (non-label).Described main magnet steel 122 and described secondary magnet steel 124 produce magnetic field, for mutual with described vibrational system 12
Act on thus drive described vibrating diaphragm 13 vibration sounding.
Described vibrational system 13 includes that vibrating diaphragm 131 is connected with vibrating diaphragm 131 and drives the sound of described vibrating diaphragm 131 vibration sounding
Circle 132, and the top dome 133 being sticked on vibrating diaphragm 131.Wherein, described voice coil loudspeaker voice coil 132 is inserted between the magnetic of described magnetic circuit system 12
In gap.Described vibrating diaphragm 131 includes that the main part 1311 that be connected fixing with top dome 133 and main body 1311 stretch out formation
And around the ring portion 1312 of this main part 1311 setting.In the present embodiment, this top dome 133 be attached at main part 1311 away from
The side of main pole core 123.
Refer to Fig. 4, for the partial enlarged drawing shown in B in Fig. 3.Described top dome 133 is near the side of described main pole core 123
Form lobe 1331, and described main pole core 123 is formed with described lobe 1331 just to setting near the side of described top dome 133
The depressed part 1231 put.Specifically, in the present embodiment, described main pole core 123 includes the first surface near described top dome 133
1232 and the second surface 1233 relative with described first surface 1232, described depressed part 1231 by described first surface 1232 to
