Vibrating diaphragm 320 is adhesively fixed on protecgulum 100 with before shell 400, above-mentioned cavity is divided into positioned at protecgulum 100 1
The preceding operatic tunes of side and the rear operatic tunes positioned at the side of shell 400.
Voice coil loudspeaker voice coil 320 and magnetic circuit system 200 are respectively positioned in the rear operatic tunes, and voice coil loudspeaker voice coil 320 is placed in the magnetic gap of magnetic circuit system 200
In 230.
According to Fig. 4, voice coil loudspeaker voice coil 320 includes the voice coil loudspeaker voice coil body 321 of annular, and voice coil loudspeaker voice coil body 321 is formed by voice coil line coiling.
Voice coil loudspeaker voice coil 320 also includes two voice coil leads 324 drawn via voice coil loudspeaker voice coil body 321.
The bottom surface 3214 of voice coil loudspeaker voice coil body 321 forms the concave part 322 caved inward and confronting grooves portion 322 is outwardly
Lug boss 323.
Concave part 322 runs through the medial surface 3212 and voice coil loudspeaker voice coil body of voice coil loudspeaker voice coil body 321 in the thickness direction of voice coil loudspeaker voice coil body 321
321 lateral surface 3211.
Concave part 322 can be in inverted U-shaped.
A part for the voice coil line of coiling voice coil loudspeaker voice coil body 321 is located in the lug boss 323.
Concave part 322 and lug boss 323 can be formed by bending voice coil line.For example, can be in the complete voice coil loudspeaker voice coil body of coiling
After 321, concave part 322 is obtained and convex by carrying out Local Contraction formula bending shaping to voice coil line in the bottom surface of voice coil loudspeaker voice coil body 321
Play portion 323.
Voice coil loudspeaker voice coil 320 can have two or more lug boss 323, per two neighboring lug boss 323 by between a concave part 322
Every.
Voice coil loudspeaker voice coil body 321 can be rectangle.Concave part 322 can on voice coil loudspeaker voice coil body 321 along its length in cut
Face is arranged symmetrically.
Voice coil loudspeaker voice coil body 321 can be rectangle.Concave part 322 can on voice coil loudspeaker voice coil body 321 in the width direction in cut
Face is arranged symmetrically.
Voice coil loudspeaker voice coil body 321 can be rectangle (including rectangle and square).The bottom surface 3214 of voice coil loudspeaker voice coil body 321 can be
The position of four edges 3213 of correspondence voice coil loudspeaker voice coil body 321 respectively sets a concave part 322.
In the embodiment shown in fig. 4, voice coil loudspeaker voice coil body 321 is rectangle, and the bottom surface 3214 of voice coil loudspeaker voice coil body 321 is in diaphone
The position for enclosing four edges 3213 of body 321 respectively sets a concave part 322, two in voice coil loudspeaker voice coil body 321 of voice coil loudspeaker voice coil 320
One lug boss 323, and respectively three lug bosses 323 of setting on two long sides of voice coil loudspeaker voice coil body 321 are respectively set on broadside.
The position 2111 for being located at the lower section of voice coil loudspeaker voice coil 320 of magnetic circuit system 200 has to be led to the avoidance for avoiding lug boss 323
Hole 213.
In a further embodiment, the avoidance through hole 213 can also avoid groove.
Setting can be corresponded with lug boss 323 by avoiding through hole 213.Each avoidance through hole 213 can also be corresponded at least
Two lug bosses 323.
Because the bottom of voice coil loudspeaker voice coil 320 has lug boss 323, magnetic circuit system 200 has the avoidance for being used for avoiding lug boss 323
Through hole 213 avoids groove, and therefore, for the loudspeaker monomer of identical size, voice coil loudspeaker voice coil 320 can be set in the height direction
It is calculated as with larger size, so, voice coil loudspeaker voice coil 320 in the height direction can be closer to magnetic circuit system 200, without generation sound
Enclose bottoming problem.Again because lug boss 323 has voice coil line, therefore, voice coil loudspeaker voice coil 320 is in upward vibration, positioned at magnetic gap 230
The accounting of the part in field homogeneity area will increase, and then can be effectively improved force coefficient BL symmetry, reduce harmonic distortion.
In addition, in the case of the size of voice coil loudspeaker voice coil 320 in the height direction is not changed, being set according to the structure of the present invention
Meter, voice coil loudspeaker voice coil 320 can be set in the height direction closer on the position of magnetic circuit system 200, without occurring voice coil loudspeaker voice coil 320 dozens
Bottom problem, so, voice coil loudspeaker voice coil 320 is in upward vibration, and the accounting positioned at the part in the field homogeneity area of magnetic gap 230 can also increase
Greatly, the effect of improved force coefficient B L symmetry can be equally obtained, harmonic distortion is reduced.
In the embodiment shown in fig. 3, magnetic circuit system 200 includes conductive magnetic yoke 210 and centring magnet 220, such as Fig. 5 and Fig. 6
Shown, conductive magnetic yoke 210 further comprises flat part 211 and extended via the edge of flat part 211 to the place lateral bending folding of voice coil loudspeaker voice coil 320
The side of sidewall portion 212 gone out.Centring magnet 220 for example by the means of bonding be fixedly connected on flat part 211 towards voice coil loudspeaker voice coil 320
On surface, to form above-mentioned magnetic gap 230 between side of sidewall portion 212 and centring magnet 220.Accordingly, the above avoids through hole 213
Or avoidance groove is opened on the flat part 211 of conductive magnetic yoke 210.
Further, the magnetic circuit system 200 can also include center magnetic conductive board, the centrally disposed magnet of center magnetic conductive board
220 towards on the surface of vibrating diaphragm 310, to play a part of correcting the magnetic line of force.
In a further embodiment, magnetic circuit system 200 can also include flat conductive magnetic yoke, centring magnet and side magnetic
Iron.Centring magnet and side magnet are fixedly connected with the surface towards voice coil loudspeaker voice coil of conductive magnetic yoke, and side magnet ring is around centring magnet
Arrangement, to form above-mentioned magnetic gap 230 between side magnet and centring magnet.Accordingly, the above avoids through hole 213 or avoided
Groove is opened in conductive magnetic yoke.
Further, the magnetic circuit system 200 can also include center magnetic conductive board and side magnetic conductive board, and center magnetic conductive board is arranged on
Centring magnet towards on the surface of vibrating diaphragm 310, the magnet towards on the surface of vibrating diaphragm 310 when magnetic conductive board is arranged on.
