Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, in order that reader more fully understands the utility model and proposes many ins and outs.But, even if without this
A little ins and outs and many variations based on following embodiment and modification, can also realize each claim of the utility model
Technical scheme claimed.
First embodiment of the present utility model is related to a kind of loudspeaker, as depicted in figs. 1 and 2, including:Upper cover plate 1, with
Upper cover plate 1 covers the lower cover 2 connect, the sounding cavity 3 collectively constituted by upper cover plate and lower cover, and is placed in sounding cavity
Sounding monomer 5 with frame 4.Magnetic circuit system (not indicated in figure) and the vibrational system with vibrating diaphragm 5-5 are housed in frame 4
Sounding cavity is separated into ante-chamber 3-1 and back cavity 3-2 by (not indicated in figure), sounding monomer 5, ante-chamber 3-1 be located at vibrating diaphragm 5-5 with it is upper
Between cover plate 1
Upper cover plate 1 includes the plummer 6 extended towards lower cover 2, in addition, plummer 6 carries frame 4, and plummer 6
Cushion pad 7 is provided between frame 4.Furthermore, it is desirable to explanation, for convenience processing and dress of the plummer 6 with upper cover plate 1
Match somebody with somebody, plummer 6 can also be single mechanism, and be removably attachable on upper cover plate 1, in the present embodiment not in tool
Body is illustrated.
Wherein, as shown in figure 3, sounding monomer 5 includes magnetic circuit system (not indicated in figure) and vibrational system (is not marked in figure
Show), magnetic circuit system includes pole piece 5-2, lower plate 5-4, with glue (for example：G-66) it is fixed on the center magnetic on lower plate 5-4
Steel 5-1, with glue (for example：S-82-1 the secondary magnet steel 5-3 on lower plate 5-4 and on the outside of the magnet steel 5-1 of center) is glued at,
Pole piece 5-2 and center magnet steel 5-1 possesses identical profile and both use glue (for example：G-66) it is connected to form one, in addition, in
Cavity (not indicated in figure) is provided between heart magnet steel 5-1 and secondary magnet steel 5-3.
Vibrational system includes vibrating diaphragm 5-5 and the voice coil loudspeaker voice coil 5-6 glued with vibrating diaphragm 5-5, and above-mentioned cavity houses voice coil loudspeaker voice coil 5-6, in addition,
And in the present embodiment, vibrating diaphragm 5-5 upper surfaces periphery is glued on cushion pad 7, vibrating diaphragm 5-5 lower surface peripheries are glued at frame
On 4.
In addition, above-mentioned frame 4 is provided with upper surface (not indicated in figure), the lower surface (in figure do not indicate) relative with upper surface
With connection upper surface, the inwall 4-1 and outer wall 4-2 of lower surface, the through hole of a collecting magnetic circuit system is surrounded by the inwall of frame 4
4-3, for convenience magnetic circuit system fixation, secondary magnet steel 5-3 and inwall 4-1 with glue (for example：G-66 it is) glued together.Separately
Outside, upper surface is glued on vibrating diaphragm 5-5.
By the above it is seen that, the reason for center magnet steel 5-1 departs from be：When loudspeaker is during falling,
Occur monomer 5 to be acted on the impact energy on sounding monomer 5 by larger impact and be concentrated mainly on lower plate 5-4, and lower folder
Ban5-4Yu centers magnet steel 5-1 is glued together with glue, so the glued construction between lower plate 5-4 and center magnet steel 5-1
Stress concentration can be caused and cause center magnet steel 5-1 easily to depart from lower plate 5-4.And in the present embodiment, sounding monomer 5
It is provided between vibrating diaphragm 5-5 peripheries and plummer 6 in cushion pad 7, loudspeaker falling process, acts on lower plate 5-4 and center
Impact energy on magnet steel 5-1 largely can be absorbed by cushion pad 7, so as to reduce the risk of center magnet steel 5-1 disengagings, enter
And and reduce the probability of speaker damage.
It is noted that as shown in figure 4, in order that plummer 6 do not influence loudspeaker normally to work, upper cover plate 1
The passage 10 of speaking that 3-1 ante-chambers are in communication with the outside is formed between lower cover 2, plummer 6 is provided with corresponding with passage 10 of speaking
Breach 6-1, ante-chamber connects through breach with passage of speaking.So as to ensure connecting for ante-chamber 3-1 and passage 10 of speaking.
In addition, can also be formed with the limited block 8 extended towards lower cover on plummer 6, limited block 8 abuts cushion pad 7
Outer.The limited block 8 can limit the movement of cushion pad 7 so that the position of cushion pad will not shift, and play well
Spacing effect.Corresponding, in the present embodiment, the location and installation of sounding monomer 5 and frame 4, keeps away for convenience
Exempt from loudspeaker falling process, the position of sounding monomer and frame 4 shifts, in the present embodiment, limited block 8 is also abutted
Frame 4 outer.
Specifically, in the present embodiment, in order that obtaining cushion pad has relatively good buffering effect, cushion pad 7 is
The soft graphite Composition spacer that flexible graphite sheet material and metallic framework are composited.In addition, cushion pad 7 can also be with nonmetallic
Flexible material is the metal jacketed gasket of inner core.In addition, cushion pad 7 can also be silica gel pad.It is preferred that, cushion pad 7 is silicon
During glue gasket, its shore hardness is less than or equal to 70 degree.It should be noted that staff can also select according to actual conditions
Other different materials make cushion pad 7.
Also, in the present embodiment, cushion pad 7 can be bonded on plummer 6.In loudspeaker falling process, due to
Cushion pad 7 is bonded on plummer 6, so cushion pad 7 will not shift, so that the rushing of can effectively absorbing of cushion pad 7
Energy is hit, while impact energy is traveled on plummer 6 in time.Specifically, the installation and fixation of cushion pad 7 for convenience,
In present embodiment, the cushion pad 7 is via adhered by double sided plaster on plummer 6.Adhered by double sided plaster can make cushion pad 7 and carrying
The sealing effectiveness of platform 6 is good, so as to not interfere with loudspeaker normal work；Can simultaneously be effectively prevent because cushion pad 7 is offset
And influence buffering effect.In actual application process, according to processing conditions and other different bondings of selection can also be needed
Mode.
Referring to Fig. 5 and Fig. 6, the utility model second embodiment also provides a kind of loudspeaker.The second embodiment is
Further improvement to this first embodiment, is mainly theed improvement is that, in this second embodiment, and the limited block 8 prolongs
The outer of frame 4 is extended, elastic washer 9 is additionally provided between limited block 8 and the outer of frame 4.During loudspeaker drops, center
The impact energy that magnet steel 5-1 is subject to also can absorb a part by elastic washer 9, reduce further the wind of center magnet steel 5-1 disengagings
Danger, so that the probability of speaker damage is lower.It should be noted that in the present embodiment, for the convenience of installation, bullet
Property packing ring 9 use material can be as cushion pad 7.Certainly, staff can also select other according to actual conditions not
Same material, present embodiment is no longer illustrated.
It should be noted that the elastic washer 9 can be integrally formed with the cushion pad 7.It is so designed that, bullet can be caused
Property packing ring 9 and cushion pad 7 assemble and more facilitate, while very close to each other between elastic washer 9 and cushion pad 7, can further carry
Rise buffering effect.In addition, in specific assembling process, elastic washer 9 can be glued on limited block 8 by double faced adhesive tape, delay
Pad 7 is rushed to be glued in frame 4 via double faced adhesive tape.Certainly, staff can also carry out gluing using other adhesives, herein not
After many elaborations.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
