In the loudspeaker operation during sounding, voice coil 43 is in variable-current and the common work of magnetic circuit system 30
Under, voice coil 43 drives vibrating diaphragm 41 to vibrate, to make the air vibration and sounding near vibrating diaphragm 41, in the process that vibrating diaphragm 41 vibrates
In, it is acted synergistically and adding the second top dome 413 and being assembled the second top dome 413 with the first top dome 412, to enhance
The intensity of the entire top dome of loudspeaker reaches the diaphagras generated in the top dome of loudspeaker when inhibiting high frequency, promotes loudspeaker
High frequency performance, improve the whole voice quality of loudspeaker, reduce the resonant frequency of the top dome of loudspeaker.
As shown in figures 1 and 3, in the present embodiment, the second top dome 413 is set to the second surface of the first top dome 412
On 4124 intermediate region position, and the second top dome 413 can be fixed on the second surface 4124 by liquid adhesive gluing.
Further, the second top dome 413 falls within orthographic projection of first top dome 412 to 411 direction of ring to the orthographic projection in 411 direction of ring
In range.In the loudspeaker of the prior art, in the vibrational system using only one tabular top dome, in speaker operation process
In, top dome is made the intermediate region of top dome be easy to produce covibration by the diaphagras that voice coil 43 is acted on and generated, then
It influences the vibration of vibrating diaphragm 41 and influences the voice quality of loudspeaker, therefore, second top dome 413 is arranged the technology of the invention
The intermediate region of one top dome 412 achievees the purpose that the resonant frequency for adjusting the intermediate region of the first top dome 412, and passes through the
Two top domes 413 enhance the self-strength of the intermediate region of the first top dome 412, occur in voiced process to restrain
Diaphagras phenomenon.
In the present embodiment, the second top dome 413 is rectangular slab, and the second top dome 413 includes two opposite first sides
4131 and connection two first sides 4131 opposite two second side 4132, two first sides 4131 are respectively perpendicular
In two long sides 4123 of the first top dome 412, and two long sides of the first top dome 412 are distinguished in two second sides 4132
4123 is concordant.Also, in the present embodiment, first surface 4122 is to be fixed on third surface 4110 by liquid adhesive gluing
On, it is convenient and efficient, and manufacture, manufacturing procedure it is low in cost.Further, the shape of the second top dome 413 is not limited to rectangle,
It is also possible to diamond shape, square, the structure of the other shapes such as circle.
Shown in Figure 4, ring 411 includes the first fixed part 4111 for being fixed on frame 10, from the first fixed part 4111
Close ring 411 inside one end to the ring portion 4112 of 411 internal stretch of ring and from ring portion 4112 to ring
Second fixed part 4113 of 411 internal stretches, surface of second fixed part 4113 far from magnetic circuit system 30 is third surface 4110,
First top dome 412 is fixed on third surface 4110.After each component part of vibrating diaphragm 41 is bonded and fixed to frame 10, such as scheme
1, shown in Fig. 3 and Fig. 4, by cover board 20 being fixed in frame 10 and the cover lives vibrating diaphragm 41, at this point, the first of vibrating diaphragm 41 is fixed
Portion 4111 clamp be assemblied in frame 10 between cover board 20, and still utilized between the first fixed part 4111 and frame 10
Liquid adhesive carries out gluing and fixes.
In the present embodiment, ring portion 4112 is bent protrusion from third surface 4110 to the direction close to magnetic circuit system 30.
In this way, on the basis of guaranteeing that ring portion 4112 realizes enhancing elastic vibration effect in the loudspeaker sounding course of work, simultaneously
The occupied space that extends outwardly can be efficiently reduced to close to the direction of magnetic circuit system 30 bending protrusion, thus further excellent
The overall dimensions Miniaturization Design for changing loudspeaker, further decreases the height dimension size of loudspeaker.
Further, loudspeaker of the invention includes two secondary magnet steel 33, and magnetic circuit system 30 further includes being stacked at main magnet steel
Main pole core 34 on 32 and the consequent pole core 35 being stacked on secondary magnet steel 33.Magnetic yoke 31 and frame 10 assembling make winner's magnet steel 32,
The components such as secondary magnet steel 33 are assemblied in the accommodating space 100 of frame 10, drive voice coil 43 under the magnetic induction effect of main magnet steel 32
It vibrates and drives 41 vibration sounding of vibrating diaphragm, also, by using main pole core 34 and the cooperation of main magnet steel 32 and secondary magnet steel 33 and master
Magnet steel 32 cooperates, and is aided with consequent pole core 35 on secondary magnet steel 33, so that magnetic circuit system 30 has stronger magnetic induction effect, from
And improve the quality of 40 vibration sounding of vibrational system of loudspeaker.
In conclusion by adding the second top dome 413 in the first top dome 412, so that the top dome intensity of loudspeaker obtains
It is promoted, achievees the effect that inhibit the diaphagras generated in the top dome of loudspeaker when high frequency, promote the high frequency performance of loudspeaker, mention
The high whole voice quality of loudspeaker, reduces the resonant frequency of the top dome of loudspeaker.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to protection model of the invention
It encloses.
