Description
Technical field
The utility model relates to the parts of loud speaker, particularly relates to a kind of passive radiator for loud speaker.
Background technology
Passive radiator is the common components in existing sound-box device, and existing passive radiator has two kinds of structures usually: one is peviform, this class passive radiator Stability Analysis of Structures, and the basin (oscillating plate) that shakes during work is not easy to rock, and product stability is good; But shake basin (oscillating plate) owing to adopting and prop up the mode that bonds of sheet (bullet ripple), so add the height of product, being not suitable for being used in thin, the little product in inner space.And make the vibration of product there is relatively large distortion because ring and sheet (bullet ripple) both vibrations there are differences.
Another kind is tabular, and ring is positioned at both sides, and the outside of ring is by stent support and protect, this class passive radiator structural instability, and the basin (oscillating plate) that shakes during work easily rocks, and product stability is poor; But owing to adopting the sticky ring of the basin (oscillating plate) that shakes, and omit and prop up the mode that sheet (bullet ripple) bonds, so reduce the height of product of knowing clearly, be applicable to being used in thin, the little product in inner space, but because product stability is poor, make the overall distortion of product relatively large, so be only suitable for for thin, the little product in the inner space low to distortion requirement.
As the passive radiator described by patent application 201020541685.8, this passive radiator has oscillating plate (vibrating diaphragm), and its outward flange is circular, and inside has through hole, thus defines annular vibration plate.The outward flange of ring-type oscillating plate is surrounded by the first ring, first ring has two extension region on continuous surface, can be fitted with vibrating diaphragm and audio amplifier first casing part respectively by these two regions, form sealing, make the air in audio amplifier leak into outside.The inward flange of annular vibration plate, namely through hole periphery has the second ring.Second ring has two extension region on continuous surface, fits respectively with vibrating diaphragm and the second casing part, forms sealing, makes the air in audio amplifier be leaked to outside.But above-mentioned structure makes passive radiator need multiple vibrating diaphragm to fit, this certainly will add difficulty and the complexity of production, and production cost is high; And this passive radiator also will ensure the balance between each vibrating diaphragm, otherwise be easy to the phenomenon bringing distortion, the stability of product is still very poor.
Summary of the invention
Primary and foremost purpose of the present utility model is to provide a kind of symmetrical passive radiator, this passive radiator reduces distortion when passive radiator works, and decrease a sheet (bullet ripple), reduce the structure of a bonding sheet simultaneously, make the height of product obtain maximum minimizing.
Another object of the present utility model is to provide a kind of based on symmetrical passive radiator, rocking when this passive radiator overcomes product work, when making product work distortion reduce, stable.
An object more of the present utility model is to provide a kind of based on symmetrical passive radiator, and it is simple that this passive radiator has structure, is easy to realize, and is convenient to carry out production and processing.
For achieving the above object, the purpose of this utility model is achieved through the following technical solutions.
A kind of symmetrical passive radiator, it includes ring, support, oscillating plate, it is characterized in that described ring has upper and lower two panels, every sheet ring is the semicircular structure with cavity, vertical folding ring is fastened on together, and described ring and support are fixed together, and is positioned at the periphery of oscillating plate.
The inner side symmetry of upper and lower two rings is adhered on oscillating plate.
Described support is divided into upper and lower two, supports upper and lower ring respectively.Like this when producing, only support need be fixed together and ring can be fixed together, producing more convenient, quick.
The middle part of described passive radiator is provided with variable weights, and described variable weights is arranged in oscillating plate, to increase the total weight of oscillating plate, and the performance parameter of the whole speaker system of weight-adjustable that adjustment is born a heavy burden.
Above-mentioned oscillating plate, it has cavity, and described variable weights is embedded in described cavity.
Above-mentioned oscillating plate, has upper and lower two pieces, is embedded with variable weights between upper and lower two pieces of oscillating plates.
Above-mentioned two pieces of oscillating plates, its two ends have groove and projection respectively, and described projection is embedded in groove, with increase oscillating plate in conjunction with compactness.
Balance leakage hole is provided with, to keep air when passive radiator works and the balance of space outerpace between described two rings.
Compared with prior art, beneficial effect is the utility model: adopt upper and lower symmetric double ring, namely respectively has a ring in the above and below of oscillating plate, and these two rings are that full symmetric is bonded on the oscillating plate of passive radiator.Upper and lower symmetrical ring is due to structural symmetry, so rocking when overcoming product work, when making product work distortion reduce, stable.
And because oscillating plate and support adopt symmetric design, same parts can together with another parts be assembled in after adjusting turnback, can adopt ultrasonic bonding that glue also can be adopted to bond between two parts, and upper and lower two parts is just the same, reduce the complexity of product, improve the simplification of Product Assembly.
Meanwhile, simply make the height of speaker product diminish in structure of the present utility model, be applicable to being used in product space thin, little, and require the high request product of little distortion.
