The first fixed frame 3 having isolation screen cloth 2 carries out injection with module shell 1 to be fixed, and indirectly isolation screen cloth 2 is fixed on module shell
In 1；Wherein, isolation screen cloth is fixing position and shape thereof all can be adjusted by the first fixed frame.
In a detailed description of the invention of the present utility model, isolation screen cloth 2 is fixed on first by double-shot moulding and fixes
In frame 3, being positioned at the isolation screen cloth 2 outside the first fixed frame 3 can be removed by laser or cross cutting, only retains first solid
Determine the isolation screen cloth 2 in frame 3, then using be molded with isolation screen cloth 2 the first fixed frame 3 as inserts, solid by double-shot moulding
Fixed to module shell 1, by being injected separately and double-shot moulding, smooth being fixed in speaker module of screen cloth 2 will be isolated, from
And the sound-absorbing granule and loudspeaker monomer to its inside is isolated.
For preventing the isolation screen cloth 2 being moulded in the first fixed frame 3 from deforming or being torn, at a tool of the present utility model
In body embodiment, some positioning bars for support limit isolation screen cloth 2 are set in the first fixed frame 3；Additionally, positioning bar
Can also prevent the first fixed frame 3 from deforming, thus more preferably the first fixed frame 3 be positioned with module shell 1.
It should be noted that the isolation screen cloth 2 of this utility model embodiment and the fixed form of the first fixed frame 3, not only
Can apply to speaker module internal, its intraware is isolated, additionally it is possible to that applies to speaker module goes out acoustic aperture
Or damping holes etc. carry out the position contacted with the external world, thus improve the waterproof and dustproof performance of speaker module, it is ensured that speaker
The performance of module is more excellent.
Such as, being respectively provided with isolation screen cloth going out acoustic aperture at damping hole, isolation screen cloth is moulded in corresponding second and fixes
On frame, the second fixed frame being molded with isolation screen cloth is fixed on and goes out on module shell corresponding to acoustic aperture and damping hole position.Its
In, the second fixed frame being molded with isolation screen cloth can be fixed on by injection or the various ways such as gluing and be gone out acoustic aperture and resistance
On the module shell that Buddhist nun hole site is corresponding.
Specifically, damping hole is arranged on the module shell at rear operatic tunes place, the operatic tunes and external environment after connection, really
The operatic tunes and front and back air pressure balance between the operatic tunes after guarantor, it is to avoid draught head impact is shaken vibration of membrane；Wherein, damping hole is playing gas
On the premise of body leakage, its aperture is the smaller the better, can be by isolation screen cloth or the damping screen increase resistance of being sticked at damping hole
Buddhist nun hole acoustic resistance, to reduce the damping hole impact on acoustical behavior.
Wherein, isolation screen cloth or the damping screen of damping hole can be moulded in second with damping hole mating shapes admittedly in advance
Determine on frame, then will be molded with the second fixed frame injection of isolation screen cloth or damping screen or be pasted and fixed on damping hole place
Module shell on.Similar approach can also be used to be configured additionally, go out the isolation screen cloth at acoustic aperture, the second fixed frame and
The structure of one fixed frame and the fixed form with isolation screen cloth thereof all can mutually be used for reference, and here is omitted.
In another detailed description of the invention of the present utility model, loudspeaker monomer includes monomer shell and is housed in outside monomer
Magnetic circuit system in shell and vibrational system, isolation screen cloth 2 is used for preventing sound-absorbing granule from entering magnetic circuit system.Wherein, vibrational system
Including the vibrating diaphragm fixed with monomer shell and the voice coil loudspeaker voice coil being fixed on vibrating diaphragm side；Magnetic circuit system then includes conductive magnetic yoke, is fixed on
The Magnet of conductive magnetic yoke center and be fixed on the Magnet washer away from conductive magnetic yoke side.
Specifically, in double magnetic circuit system, Magnet farther includes centring magnet and the limit magnetic arranged around centring magnet
Ferrum, washer includes the center washer corresponding with centring magnet respectively and limit Magnet and limit washer；Centring magnet and center washer with
Forming magnetic gap between limit Magnet and limit washer, voice coil loudspeaker voice coil is hung in magnetic gap, when the voice coil loudspeaker voice coil being in magnetic field has tone currents
When flowing through, alternate motion can be produced by an alternation motive force, thus drive vibrating diaphragm to shake, and then repeatedly promote air to send out
Sound.
Additionally, in speaker module in this utility model executes example, also include electric connection board, one end of electric connection board with
Voice coil loudspeaker voice coil turns on, and the other end turns on the external circuit of speaker module.Wherein, the shell fragment of loudspeaker monomer is exposed is fixed on monomer
On shell, the while of shell fragment, lead-in wire and electric connection board with voice coil loudspeaker voice coil turn on, when electric connection board turns on external circuit, it is possible to realize
Voice coil loudspeaker voice coil and the conducting of external circuit, thus realize the connection of loudspeaker monomer peripheral circuits.Wherein, electric connection board can use
FPCB (Flexible Printed Circuit Board, flexible printed circuit board).
It should be noted that the module shell 1 of this utility model embodiment can include adaptive connection module upper casing and
Module lower casing, fixed frame (the first fixed frame and/or the second fixed frame) position is set, can be according to production requirement or needs
The position relationship carried out between the intraware isolated is adjusted, and the shape of fixed frame and size can also be installed according to it
Position adjusts accordingly.
By above-mentioned embodiment it can be seen that the speaker module of this utility model offer, screen cloth or resistance will be isolated
The similar structures injections such as Buddhist nun's net are fixed in default fixed frame, by fixed frame injection being fixed on the shell of product, real
Now isolation screen cloth or damping screen etc. and the strong bonded of speaker module, it is possible to partially or net is broken etc. no to be prevented effectively from net leakage, net
Good problem；Additionally, fixed frame may be arranged as rule or various shape, the applied range, it is possible to effectively carry such as irregularly
