Description

A kind of assembly fixture for Microspeaker
Technical field
A kind of Microspeaker field is the utility model is related to, more specifically, is related to a kind of for Microspeaker Assembly fixture.
Background technology
Microspeaker, on mobile phone or tablet personal computer, it is one of indispensable part, can be allowed by loudspeaker Mobile phone or tablet personal computer can play the function of reaching and amplify, loudspeaker it is good with it is bad, also determine the quality of tonequality.
With the development of the electronic products such as mobile phone or tablet personal computer, requirement more and more higher of the people to tonequality, many institute's weeks The Microspeaker known includes magnetic circuit system, vibrational system and accessory system, wherein, magnetic circuit system includes magnetic conductive board and magnet And washer, vibrational system includes vibrating diaphragm and voice coil loudspeaker voice coil, and accessory system then includes shell and the protecgulum to be cooperated with shell, shakes Dynamic system and magnetic circuit system are contained within the cavity that protecgulum is formed with shell.The lead of voice coil loudspeaker voice coil is typically by conducting structure and outside Portion's circuit turn-on, so, after voice coil loudspeaker voice coil receives outside AC signal, reciprocating cutting magnetic can be done in the presence of electromagnetic field The motion of the line of force, connected diaphragm oscillations are driven, so that outwardly radiative acoustic wave, finally converts electrical energy into acoustic energy.
Existing Microspeaker is typically to enter the parts such as pedestal, voice coil loudspeaker voice coil, protecgulum, vibrating diaphragm, magnetic circuit using assembly fixture Luggage is matched somebody with somebody.Current manufacturing process mainly has problems with:
(1) use assembly fixture but design is unreasonable.Existing assembly fixture, as shown in Figures 1 to 3, first in protecgulum work Load protecgulum in dress tool, then load vibrating diaphragm, then the tool fixture and protecgulum tool fixture that pedestal and voice coil loudspeaker voice coil will be equipped with Fasten, then remove pedestal frock with ejection fixture, product is stayed in protecgulum frock, subsequently assembled, still, is being assembled There is the tool fixture of pedestal and voice coil loudspeaker voice coil and during protecgulum tool fixture fastening, voice coil loudspeaker voice coil easily deform vibrating diaphragm top, produces displacement, Because vibrating diaphragm toughness is very poor, it is not easy to recover after deformation, easily produces noise, so as to influences the acoustical quality of Microspeaker.
(2) existing process flow scheme design is unreasonable, and more in current manufacturing process, current bottleneck station is to raise one's voice Device pure tone detection, it is in the way in audition stage:Remove protecgulum tool → taking-up semi-finished product → assembling magnetic circuit one time audition → general The non-defective unit assembly fixture of audition simultaneously beats magnetic circuit fixing glue.It means that pure tone detection must be by semi-finished product from frock Remove one by one, then magnetic circuit and gluing are ressembled in frock after audition sound, is at least pacified wherein semi-finished product are removed Arrange 1 worker;Semi-finished product are ressembled into frock and consume 1 worker, two to three operations are just wasted more in whole process Worker and substantial amounts of production stand-by period.
The content of the invention
In view of the above problems, the purpose of this utility model is to provide a kind of assembly fixture for Microspeaker, both keeps away Exempt from caused diaphragm deformation and can in assembling process to reduce production stage, save manpower.
The utility model provides a kind of assembly fixture for Microspeaker, including protecgulum tool fixture, have with The pedestal tool fixture for the positioner that protecgulum tool fixture coordinates, the pressure with the positioner coordinated with protecgulum tool fixture Pad-pasting fixture tool, ejection fixture and U iron tool fixtures A with the positioner coordinated with protecgulum tool fixture, with U The U iron tool fixtures B for the positioner that iron tool fixture A coordinates, there is listening for the positioner coordinated with protecgulum tool fixture Sound tool fixture;The groove that the protecgulum tool fixture surface is placed for protecgulum and vibrating diaphragm, bottom portion of groove are provided with through hole;The pressure Pad-pasting fixture tool has the elastic bumps structure similar with the shape of through holes;The pedestal tool fixture be provided with for pedestal and The groove that voice coil loudspeaker voice coil is placed, while it is provided with the groove passed through for ejection fixture;The ejection fixture is slender rod shaped;The U iron Contact surface leaves the groove placed for magnetic circuit after tool fixture A and U iron tool fixtures B is fastened, and bottom portion of groove is equipped with U-shaped and led to Groove.
Furthermore it is preferred that scheme be the through hole of the protecgulum tool fixture bottom and to overlay the elastic convex of film tool fixture It is round rectangle to play structure, and similar keyway coordinates;The groove and vibrating diaphragm, voice coil loudspeaker voice coil of the protecgulum tool fixture are also fillet square Shape.
It is further preferred that including multiple through holes being arranged side by side.
It is further preferred that the distance between two adjacent through holes are 5 centimetres~20 centimetres.
It is further preferred that the elastic bumps structure has the shape being adapted with the vibrating diaphragm (3).
It is further preferred that the elastic bumps structure by paste or magnetic absorption be arranged at it is described pressure pad-pasting fixture control On the surface for having (5).
It is further preferred that the vibrating diaphragm (3) overlays the height on the surface of film tool fixture (5) described in after definition assembling For H, then, the height of elastic bumps structure is H ± 2 millimeter.
It is further preferred that the height of the elastic bumps structure is H ± 1 millimeter.
Using the above-mentioned assembly fixture according to Microspeaker of the present utility model, controlled by the protecgulum frock with hole Have and the mutual cooperation for overlaying film tool fixture with elastic bumps structure replaces integrally formed protecgulum work in the prior art Tool is filled, a support force is provided to vibrating diaphragm equivalent to when vibrating diaphragm and pedestal make-up, voice coil loudspeaker voice coil can be prevented vibrating diaphragm top Deformation, so as to improve the acoustical quality of Microspeaker;Meanwhile the U iron tool fixture A of magnetic circuit will be equipped with being equipped with The protecgulum tool fixture of semi-finished product fastens, and is placed on together on audition tool, pushes magnetic circuit using board and is assembled to Completes audition behind position, then behind buckle into back cavity audition tool and can complete a back cavity audition, whole audition process without Tool, simple and convenient need to be removed, processing step is enormously simplify, has saved manpower and entreprise cost.
In order to realize above-mentioned and related purpose, one or more aspects of the present utility model include will be explained in below And the feature being particularly pointed out in the claims.Some examples of the present utility model are described in detail in following explanation and accompanying drawing Property aspect.However, what is indicated in terms of these is only some modes in the various modes for can be used principle of the present utility model. In addition, the utility model is intended to include all these aspects and their equivalent.
