10。
Wherein, at the insertion of bed die 10 opening 40, the upper surface of bed die 10 is higher than at the pre-determined distance h of opening 40.Specifically
Ground, pre-determined distance h can be 0.05mm~0.15mm (millimeter), it is preferable that the pre-determined distance is 0.1mm.
In the cavity of ring cavity body 30, the lower surface of back pole plate 20 is in contact back pole plate 20 with the upper surface of bed die 10.
Back pole plate 20 in the cavity, is snapped mold 50 and is snapped to the upper plane of bed die 10 from top to bottom, the bottom of due to
The presence of mould 10, back pole plate 20 are fixed in 30 lower end of ring cavity body, and the distance away from opening 40 is the position of 0.05mm~0.15mm
It sets, back pole plate 20 and ring cavity body 30 are in close-fitting state at this time.Vibration, back pole plate 20 are generated in assembling process
It will not fall off from the opening 40 of ring cavity body 30, so as to avoid the generation of defective products.
Further, back pole plate 20 is the back pole plate greater than two holes, such as four hole back pole plates.Back pole plate more than hole number can
To reduce generated damping when indentation, indentation precision is easier to control, it is easier to which back pole plate 20 is pressed to ring cavity
The position that distance of 30 lower end of body away from opening 40 is 0.05mm~0.15mm.
The material of ring cavity body 30 can be plastic material.
Opening 40 can be straight tube mouth, be also possible to the opening with tilt angle, such as flare openings.
Further, referring to Fig. 3, the structural schematic diagram of the mounting device bed die 10 in Fig. 3 Fig. 1, Fig. 2.Bed die 10 wraps
Include embedded division 11 and bottom 12.The shape of embedded division 11 and the shape of opening 40 match, and embedded division 11 can be embedded into opening
In 40.The opening 40 of Fig. 1 and Fig. 2 is also possible to the opening of other shapes, such as straight barrel type by taking flare openings as an example.With
Flare openings are corresponding, and shape and the flare openings 40 of embedded division 11 match, and embedded division 11 is fixed to be opened embedded in horn-like
At mouth 40.Bottom 12 includes two extensions in the extension 13 of embedded division 11, upper surface and the ring cavity body 30 of extension 13
Bottom surface is in contact.
The upper surface of embedded division 11 in above-mentioned figure is a plane.It the upper surface of embedded division 11 can also be flat for two
Face, that is, embedded division 11 divides for two parts, specifically as shown in figure 4, two planes are located in the two of flare openings 40
At side.Relative to the embedded division of a plane, the embedded division structure of two planes is more succinct, more saving material.
Further, embedded division 11 can be softwood matter, and extruding is fixed at flare openings 40；
Embedded division 11 or hard material, are pasted and fixed at flare openings 40, and stickup can be viscous to can remove
Patch, so that embedded division 11 is easily peelable.

Positioning device, the first positioning device mutually fasten with the second positioning device, for assisting touching for back pole plate 20 and bed die 10
The success rate that back pole plate 20 touches bed die 10 is improved in position.First positioning device can be set in the lower surface of back pole plate 20
Center also can be set in non-central position.The position of second positioning device and the first positioning device matches.
Specifically, which is convex object, which is groove；Alternatively, first positioning device
For groove, which is convex object.Convex object and groove mutually fasten.
Snapping mold 50 is to push down on back pole plate 20 by the driving of high-precision embedment pressure device, embedment pressure dress
It sets and is driven using servo line motor.Bed die 10 is a high-precision bed die, and high-precision bed die is using laser processing skill
Art.The insertion precision and bed die precision of back pole plate 20 all control in the 0.05mm margin of tolerance in the present embodiment, to realize
The rate of good quality rate of microphone assembly assembling, and then improve the quality and efficiency of assembling microphone.
Further, back pole plate 20 is snapped at 40 pre-determined distance h of distance opening, it is after removing bed die 10, this is new
Type microphone assembly (i.e. the back pole plate 20 of ring cavity body 30 and embedded rings cavity 30) is transported to down by transfer matic vibratory conveyors
At one of assembling procedure, vibratory conveyors are vibrated, and back pole plate 20 can be vibrated and be open at 40, but not fall off and open out
Mouth 40 then completes the overall package of microphone, specifically in the embedding back pole plate 20 and ring being integrated at lower one of assembling procedure
Copper ring, diaphragm, PCB (Printed Circuit Board) plate are put into cavity 30, packaged shell completes assembling.
In the embodiment of the present invention, using setting bed die, back pole plate is installed to the exit pre-determined distance from ring cavity body
The yields of assembly is improved, was being assembled so that back pole plate will not fall off from ring cavity body because of the vibration in assembly in position
Yields can achieve 99.8% in journey.
The embodiment of the invention also provides a kind of novel microphone assemblies, including having the ring cavity body of opening and by such as
The preceding mounting device peace is limited in the back pole plate at the opening pre-determined distance away from ring cavity body, and back pole plate is greater than two holes
Back pole plate, specifically, back pole plate are four hole back pole plates.
Novel microphone assembly in the present embodiment, using be greater than two holes back pole plate, it is possible to reduce indentation when
Damping caused by waiting, indentation precision are easier to control, it is easier to which back pole plate is pressed to ring cavity body lower end away from the default of opening
The position of distance.In assembling, since using bed die is arranged, back pole plate to be installed to the exit pre-determined distance from ring cavity body
Position improve the yields of assembly so that back pole plate will not fall off from ring cavity body because of the vibration in assembly, assembling
Yields can achieve 99.8% in the process.Also, novel microphone assembly process structure is simple and reliable, and stability is good, acoustics
The frequency response of index, sensitivity, consistency increase, and manufacture craft is simple, at low cost, are suitble to produce in enormous quantities.
It is right the above are the description of mounting device and novel microphone assembly to microphone assembly provided by the present invention
