Abstract
The present invention is a kind of vibrating diaphragm having and strengthening medium and low frequency section, and vibrating diaphragm includes three layers: ground floor is film plating layer, and Coating Materials is titanium；The second layer is basic unit, and basic unit is polyarylate layer；Third layer is composite bed, and composite bed is layer of polyurethane；Described basic unit is between film plating layer and composite bed, and film plating layer is plated in basic unit, and the basic unit after plated film is compound with composite bed constitutes vibrating diaphragm；Vibrating diaphragm uses polyarylate titanizing, and composition compound with polyurethane, has light weight, good rigidly, advantage attractive in appearance.
Description
Technical field
The present invention relates to diaphragm of loudspeaker field, a kind of have the vibrating diaphragm strengthening medium and low frequency section.
Technical background
At present, market mostly using metal vibration diaphragm or plastics vibrating diaphragm, the most frequently used material of plastics vibrating diaphragm has poly-to benzene
Naphthalate (Polyethylene terephthalate is called for short PET), PEN
(Polyethylene naphthalate is called for short PEN), Polyetherimide (Polyetherimide is called for short PEI) etc., these
Material is cheap, has certain practicality, but, their rigidity is the best, and quality is the most heavier, and therefore manufacture shakes
Film middle pitch and low tonequality are poor；Metal vibration diaphragm rigidity is very strong, and using aluminum metal or its alloy product at present is at most, but, gold
Belong to vibrating diaphragm and " metallic sound ", i.e. high-frequency resonance easily occur, and the heavier mass of metal, overall middle pitch or bass effect compare
Difference, therefore, to the bass produced or middle pitch vibrating diaphragm, is necessary for solving rigidity and the problem of weight.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of vibrating diaphragm having and strengthening medium and low frequency section, vibrating diaphragm is adopted
Use polyarylate titanizing, and composition compound with polyurethane, the advantage with light weight, good rigidly.
Technical scheme is as follows: a kind of have the vibrating diaphragm strengthening medium and low frequency section, shakes including vibrating diaphragm with for fixing
The copper ring of film, copper ring is bonded together with vibrating diaphragm temperature-sensitive glue, because heat-sensitive glue water low price, and effect is pretty good；Shake
Film includes three layers: ground floor film plating layer, and Coating Materials is titanium；The second layer is basic unit, and basic unit is polyarylate layer；Third layer is compound
Layer, composite bed is layer of polyurethane；Described basic unit is between film plating layer and composite bed, and film plating layer is electroplated in basic unit, plated film
After basic unit and composite bed compound to constitute thickness be the vibrating diaphragm of 0.008mm ~ 0.300mm, and compound mode be in the industry conventional again
Conjunction mode, simple and convenient；Polyarylate matter is soft, relatively good to distortion, and low frequency is clear, but non-refractory, is weak to benzene, but thereon
After the titanizing of face, polyarylate just light weight and hard, beneficially molding, rigidity is pretty good, and when and after polyurethane is combined, it is possible to
High temperature resistant and toluene is tested；Meanwhile, vibrating diaphragm has projection decorative pattern, decorative pattern shape be point, straight line, curve, circle, ellipse,
Triangle, prismatic, rectangle or abnormity, these decorative patterns are mainly used for strengthening the performance of vibrating diaphragm, strengthen middle pitch and the effect of bass.
Above technical scheme is used to provide the benefit that:
1. the present invention uses polyarylate titanizing, and compound with polyurethane constitutes vibrating diaphragm, the advantage with light weight, good rigidly, very well
Solve middle pitch and often there is the problem that tonequality is the best in bass.
2. the present invention uses the mode of polyarylate titanizing to do vibrating diaphragm, because the heat stability of titanium is fine, fusing point is 1660 ±
10 DEG C, boiling point is 3287 DEG C, and under room temperature, titanium becomes the oxide-film of one layer of very thin densification with gasification symphysis, and this layer of oxide-film can also
Protection vibrating diaphragm.
3. present invention incorporates each characteristic of titanium, polyurethane and polyarylate, high temperature resistant can test with toluene, possess excellent
The good impact of performance.
4. the copper ring of the present invention and vibrating diaphragm viscous with temperature-sensitive glue and together with, heat-sensitive glue water low price, and effect is very
Good.

Specific embodiment
As shown in drawings, a kind of have the vibrating diaphragm strengthening medium and low frequency section, including vibrating diaphragm 1 with for fixing the copper ring 2 of vibrating diaphragm,
Copper ring is bonded together with vibrating diaphragm temperature-sensitive glue, because heat-sensitive glue water low price, and effect is pretty good；Vibrating diaphragm 1 includes three
Layer: ground floor is film plating layer 3, and Coating Materials is titanium；The second layer is basic unit, and basic unit is polyarylate layer 4；Third layer is composite bed,
Composite bed is layer of polyurethane 5；Described film plating layer 3 is between basic unit and composite bed, and film plating layer is electroplated in basic unit, plated film
After basic unit and composite bed compound to constitute thickness be the vibrating diaphragm of 0.008mm ~ 0.300mm, the conventional mode of compound mode is combined；
Polyarylate matter is soft, relatively good to distortion, and low frequency is clear, but non-refractory, is weak to benzene, but after titanizing in the above, poly-virtue
Ester just light weight and hard, beneficially molding, rigidity is pretty good, and when and polyurethane compound after, it is possible to high temperature resistant and toluene survey
Examination；Meanwhile, vibrating diaphragm has projection decorative pattern 6, decorative pattern 6 shape be point, straight line, curve, circle, ellipse, triangle, prismatic,
Rectangle or abnormity, these decorative patterns 6 are mainly used for strengthening the performance of vibrating diaphragm, strengthen middle pitch and the effect of bass.
The present invention uses polyarylate titanizing, and compound with polyurethane constitutes vibrating diaphragm, the advantage with light weight, good rigidly, very
Good solve middle pitch and the problem that tonequality is the best often occurs in bass, and, the copper ring of the present invention and vibrating diaphragm temperature-sensitive glue
Viscous and together with, can high temperature resistant and toluene test, possess the excellent impact of performance.
It is above the accompanying drawing combining in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
