Abstract
The invention discloses chamber enclosure before a kind of moving-iron receiver, including shell, the inside of described shell has two long inwalls, it is respectively provided with two vibrating diaphragm positioning boss on each described long inwall, described vibrating diaphragm positioning boss is in same level, on described long inwall, the position in the centre of two described vibrating diaphragm positioning boss arranges reinforcement boss, and the described reinforcement boss on two described long inwalls is in same level.Before moving-iron receiver of the present invention, chamber enclosure can carry out bilateral location by four vibrating diaphragm positioning boss and two reinforcement boss to vibrating diaphragm, the positioning precision making vibrating diaphragm is greatly improved, facilitate production, improve yields, thus improve receiver's end properties, make high frequency concordance significantly optimize.
Description
Technical field
The invention belongs to moving-iron receiver parts, more particularly it relates to chamber enclosure before a kind of moving-iron receiver.
Background technology
Moving-iron receiver is mainly used in the wearable device such as sonifer and earphone, and client is for its acoustic response curve
Coherence request is the highest.Particularly earphone client, values the concordance at the high-frequency resonance peak of receiver very much.Because this meeting
Directly affect frequency dividing and the sound adjustment of earphone.
Fig. 1 is the figure that cuts open of existing receiver, and vibrating diaphragm 92 is the necessary component in receiver, when receiver works, and electricity
Pivot 93 vibrates, and drives diaphragm oscillations by conductive bar 94, thus produces sound.Sound is derived by sender 95.
Fig. 2 is the schematic diagram that vibrating diaphragm 92 is assembled in front chamber enclosure 91, and vibrating diaphragm 92 is fit directly in front chamber enclosure 91.Logical
Before crossing, 4 boss in chamber enclosure 91 position, and i.e. frame is on these 4 boss.
Further, carry out sealing along the gap between vibrating diaphragm 92 and front chamber enclosure 91, i.e. assembled.
From the point of view of from the acoustical behavior of receiver, the vibrating diaphragm 92 position location in front chamber enclosure 91, sound can be directly affected
Answer the high-frequency resonance peak of curve: being located proximate to of vibrating diaphragm 92/away from front chamber enclosure 91 top, can cause the reach of high-frequency resonance peak/
Rear shifting.
According to existing design, vibrating diaphragm 92 is simply shelved on 4 boss on front chamber enclosure 91, the most monolateral location.Shake
Film 92 cannot be fitted on boss completely by self gravitation, needs to assemble by tweezers pressure auxiliary when operator assembles, so
The position of actual location has certain deviation, and has the extra yields loss that operational error causes.It addition, the glue of sealing
Certain impact in the curing process, also can be caused in the position of vibrating diaphragm 92 by water.This may result in the high-frequency resonance of receiver's finished product
Peak concordance is the best.
Summary of the invention
The invention discloses chamber enclosure before a kind of moving-iron receiver, improve the vibrating diaphragm setting accuracy at shell, thus
Improve the high frequency concordance of the acoustical curve of receiver's finished product.
The technical solution adopted in the present invention is:
Chamber enclosure before a kind of moving-iron receiver, including shell, the inside of described shell has two long inwalls, each described
Be respectively provided with two vibrating diaphragm positioning boss on long inwall, described vibrating diaphragm positioning boss in same level, on described long inwall
The position of the centre of two described vibrating diaphragm positioning boss arranges reinforcement boss, and the described reinforcement boss on two described long inwalls exists
In same level.
Further, the difference in level of boss and vibrating diaphragm positioning boss is strengthened within ± 0.03mm.
Use after technique scheme, before moving-iron receiver of the present invention chamber enclosure can by four vibrating diaphragm positioning boss and
Two reinforcement boss carry out bilateral location to vibrating diaphragm, make the positioning precision of vibrating diaphragm be greatly improved, and facilitate production, improve non-defective unit
Rate, thus improve receiver's end properties, make high frequency concordance significantly optimize.

Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.Following example are only used for more clear
Chu's ground explanation technical scheme, and can not limit the scope of the invention with this.
As it is shown on figure 3, chamber enclosure before a kind of moving-iron receiver, for vibrating diaphragm 4 is accurately positioned installation, including shell 1,
The inside of shell 1 has two long inwalls 11, and each long inwall 11 is respectively provided with two vibrating diaphragm positioning boss 2, vibrating diaphragm convex
Platform 2, in same level, long inwall 11 is arranged in the position of the centre of two vibrating diaphragm positioning boss 2 and strengthens boss 3, two
Described reinforcement boss 3 on described long inwall 11, in same level, strengthens boss 3 high with the level of vibrating diaphragm positioning boss 2
Degree difference is within ± 0.03mm.
As shown in Figure 4, before moving-iron receiver of the present invention, chamber enclosure can pass through four vibrating diaphragm positioning boss 2 and two reinforcements
Boss 3 carries out bilateral location to vibrating diaphragm 4, and vibrating diaphragm 4 can be accurately positioned in shell 1, fixed with vibrating diaphragm owing to strengthening boss 3
The difference in level of position boss 2, within ± 0.03mm, makes the location of vibrating diaphragm 4 can also control within this tolerance, and it is fixed to make
Position precision is more accurate, by the Position Design of each boss in chamber enclosure 1 before controlled moving-iron receiver, makes determining of vibrating diaphragm 4
Position precision is greatly improved, thus improves receiver's end properties, makes high frequency concordance significantly optimize, owing to strengthening boss 3
Caning be controlled in ± 0.03mm with the difference in level of vibrating diaphragm positioning boss 2, when carrying out vibrating diaphragm 4 and assembling, assembly precision is carried
Rise, facilitate production, improve yields.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
