Abstract
The utility model relates to an attaching apparatus, especially to a composite diaphragm attaching apparatus. The apparatus comprises a guide sleeve (1), push blocks (2), springs (3) and a pedestal (4). The top end of the guide sleeve (1) is equipped with steps, diaphragms are placed in a band-shaped diaphragm strip material (8), and the shapes of the steps match the shapes of recess parts in the periphery of the band-shaped diaphragm strip material (8); symmetrical hollow pipelines (5) are arranged in the guide sleeve (1), the push blocks (2) are respectively arranged in the hollow pipelines (5), and the lower ends of the push blocks (2) penetrates through the guide sleeve (1) and are connected with the pedestal (4) by penetrating through the springs (3); and when the springs (3) are static, the top ends of the push blocks (2) are lower than the upper edges of the hollow pipelines (5), and the top ends of the push blocks (2) are at the same horizontal surface. The composite diaphragm attaching apparatus has the advantages that structure and operation are simple, central positions of aluminum foils and the diaphragms can be rapidly and accurately positioned, and the problem of attaching offset can be effectively solved.
Description
Technical field
The utility model relates to a kind of paster apparatus, relates in particular to composite diaphragm paster apparatus.
Background technology
Smart mobile phone develops rapidly, and increasing function, application are developed, wherein for the tonequality of loud speaker, the requirement of audio is also more and more higher.That mobile phone speaker has is ultra-thin, lightweight, the feature such as little that takes up room, and its energy conversion efficiency is high, consumes littlely, and loud speaker adopts Whole frequency band design, has wide directive property, low distortion feature.As the core vibrating diaphragm of loud speaker, the quality of vibrating diaphragm has influence on the tonequality of loud speaker, to weeding out the old and bring forth the new of vibrating diaphragm, is exactly therefore the transformation to loud speaker.For traditional vibrating diaphragm, existing composite diaphragm is to be bonded by two parts, and aluminium foil and vibrating diaphragm are bonding.But in the adhesion process of aluminium foil and vibrating diaphragm, the bonding generation position deviation of aluminium foil and vibrating diaphragm can cause the high frequency distortion of loud speaker, when serious, also can there is the situations such as aluminium foil comes off.
Utility model content
The utility model is to overcome above-mentioned weak point, and object is to provide composite diaphragm paster apparatus, solves paster problem of misalignment, avoids the situations such as loudspeaker distortions, aluminium foil that paster is not just causing come off.
The utility model is to achieve the above object by the following technical programs: composite diaphragm paster apparatus, comprising: guide pin bushing, pushing block, spring, base; Described guide pin bushing top is provided with step, and vibrating diaphragm is placed in banded vibrating diaphragm billot, and the depression position shape of step shape and banded vibrating diaphragm billot periphery matches; In guide pin bushing, be provided with symmetrical hollow pipeline, be provided with pushing block in hollow pipeline, pushing block lower end passes guide pin bushing and is connected with base through spring; When spring is static, pushing block top is lower than the upper edge hole of hollow pipeline, and when guide pin bushing is descending, pushing block moves upward in hollow pipeline, and the top of each pushing block is in same level.
As preferably, described pushing block top and guide pin bushing form groove, place aluminium foil in groove, and when spring is static, aluminium foil top is lower than the upper edge hole of hollow pipeline.
The beneficial effects of the utility model are: the utility model is put into groove by aluminium foil, banded vibrating diaphragm billot is attached to guide pin bushing top, the quick center of location aluminium foil and vibrating diaphragm, press down guide pin bushing make aluminium foil and vibrating diaphragm bonding, bonding good banded vibrating diaphragm billot is taken off.Therefore the utility model is simple in structure, easy and simple to handle, fast, correctly locates the center of aluminium foil and vibrating diaphragm, can effectively solve paster problem of misalignment, avoids the situations such as loudspeaker distortions, aluminium foil that paster is not just causing come off.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of the banded vibrating diaphragm billot that be placed with vibrating diaphragm corresponding with utility model structure;
In figure: 1, guide pin bushing; 2, pushing block; 3, spring; 4, base; 5, hollow pipeline; 6, groove; 7, aluminium foil; 8, banded vibrating diaphragm billot.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further, but protection range of the present utility model is not limited in this:
Embodiment 1: as shown in Figure 1, composite diaphragm paster apparatus, comprising: guide pin bushing 1, pushing block 2, spring 3, base 4; Described guide pin bushing 1 top is provided with step, and vibrating diaphragm is placed in banded vibrating diaphragm billot 8, and the depression position shape of step shape and banded vibrating diaphragm billot 8 peripheries matches; In guide pin bushing 1, be provided with symmetrical hollow pipeline 5, be provided with pushing block 2 in hollow pipeline 5, pushing block 2 lower ends pass guide pin bushing 1 and are connected with base 4 through spring 3; When spring 3 is static, pushing block 2 tops are lower than the upper edge hole of hollow pipeline 5, and when guide pin bushing 1 is descending, pushing block 2 moves upward in hollow pipeline 5, and the top of each pushing block 2 is in same level; Described pushing block 2 tops and guide pin bushing 1 form groove 6, the interior placement aluminium foil 7 of groove 6, and when spring 3 is static, aluminium foil 7 tops are lower than the upper edge hole of hollow pipeline 5.
This device has two hollow pipelines, therefore can bonding two parts of composite diaphragms of while.As shown in Figure 2, every two of banded vibrating diaphragm billot 8 is one group, and the concave shape that every group of vibrating diaphragm billot moulding rear perimeter edge has and the step shape on guide pin bushing 1 top match.
During concrete use, comprise the following steps:
Step 1: 2 aluminium foils 7 are put into respectively to corresponding groove 6, and upward, reverse side carries viscosity to aluminium foil 7 reverse side;
Step 2: the banded vibrating diaphragm billot 8 processing is covered to guide pin bushing 1 top, and now the center of aluminium foil 7 is relative with the center of vibrating diaphragm, the location that completes aluminium foil 7 and vibrating diaphragm;
Step 3: smooth banded vibrating diaphragm billot 8 and press down with hand, banded vibrating diaphragm billot 8 moves downward with guide pin bushing 1, and aluminium foil 7 moves upward under the promotion of pushing block 2 in hollow pipeline 5, the middle cardiosymphysis of aluminium foil 7 and vibrating diaphragm;
Step 4: take off bonding good composite diaphragm, spring 3 automatically resets, repeating step 1.
Described in above, be specific embodiment of the utility model and the know-why used; if the change of doing according to conception of the present utility model; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, must belong to protection range of the present utility model.
