[specific embodiment]
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
It as shown in Figure 1 to Figure 3, is a kind of loudspeaker of the offer of the utility model embodiment one.The loudspeaker includes magnetic circuit
System 1, vibrational system 2, the frame 3 for accommodating magnetic circuit system 1 and vibrational system 2 and the upper cover 4 being covered in frame 3, magnetic circuit
System 1 includes the lower clamp plate 11 connecting with 3 lower end of frame, the main magnet steel 12 being placed on lower clamp plate 11, is placed on lower clamp plate 11 simultaneously
Positioned at main 12 two sides of magnet steel secondary magnet steel 13 and be placed in upper clamp plate 14 of the secondary magnet steel 13 far from 11 side of lower clamp plate, upper clamp plate 14
By glue gluing between secondary magnet steel 13, magnetic gap 10 is formed between main magnet steel 12 and secondary magnet steel 13.Vibrational system 2 includes setting
In in magnetic gap 10 voice coil 21, connect far from the side of lower clamp plate 11 with voice coil 21 vibrating diaphragm 22, to be fixed on main magnet steel 12 remote
Pole piece 23 from 11 one end of lower clamp plate and it is fixed on damping sheet 24 of the vibrating diaphragm 22 back to 21 side of voice coil, the periphery folder of voice coil 21
It is placed between upper cover 9 and frame 3.
In above-described embodiment, upper clamp plate 14 includes the bottom surface 141 connecting with secondary magnet steel 13, is opened up on the bottom surface 141 useful
In the notch 1411 for accommodating glue, which is located at the bottom surface 141 of upper clamp plate 14 close to one end of magnetic gap 10.The notch
