Abstract
The invention discloses a long-life vibration plate for a loudspeaker. The long-life vibration plate at least comprises combination of nylon, kawo fibre and jute fibre. In the scheme, the material formula of the traditional vibration plate is improved; due to the introduced combined modified fibre, the relatively low moisture resistance of the vibration plate in the prior art is overcome effectively; furthermore, because the compound fibre is improved, the vibration plate has excellent structural strength, decay resistance and fatigue durability; the better plumpness of the loudspeaker can be kept in a full frequency band for a long time; therefore, distortion of the loudspeaker is greatly inhibited; and the tone quality of the loudspeaker is improved.
Description
Technical field
The present invention relates to a kind of acoustical material, be specifically related to a kind of high life oscillating plate for loud speaker.
Background technology
Oscillating plate is one of major part of loud speaker, has conclusive impact to the performance of loud speaker and tonequality.The oscillating plate that performance is outstanding needs to possess lighter weight, and can raise the efficiency like this, excessive characteristic is good; Need to possess simultaneously and larger raise a gram coefficient, expand frequency range with this.
There is following defect in conventional loudspeakers oscillating plate used: 1) moisture resistance is poor; 2) structural stability is poor; 3) spring rate is low, and fatigue durability is poor.These factors can have a strong impact on performance and the tonequality of loud speaker.
Summary of the invention
For the deficiencies in the prior art part, the object of the present invention is to provide a kind of high life oscillating plate for loud speaker, it can have excellent resistance to water, moisture-proof, fatigue durability and structural strength, thus reduces the distortion of loud speaker, improves the tonequality of loud speaker.
Technical scheme of the present invention is summarized as follows:
For a high life oscillating plate for loud speaker, it at least includes the combination of Fypro, bombax cotton and tossa.
Preferably, the described high life oscillating plate for loud speaker, wherein, with parts by weight, Fypro 100 parts, bombax cotton 24 ~ 25 parts, tossa 9 ~ 10 parts.
Preferably, the described high life oscillating plate for loud speaker, wherein, also comprises polyvinyl alcohol 3 ~ 4 parts.
Preferably, the described high life oscillating plate for loud speaker, wherein, the thickness of described oscillating plate is 0.1 ~ 0.3mm.
The invention has the beneficial effects as follows: this case is by improving the material prescription of traditional oscillating plate, the composite type modified fiber introduced is effective overcomes the defect that in prior art, oscillating plate moisture-proof is lower, and, due to the improvement of composite fibre, oscillating plate is made to have outstanding structural strength, decay resistance and fatigue performance, make loud speaker can possess good plumpness at full frequency band for a long time, thus greatly inhibit the distortion of loud speaker, improve the tonequality of loud speaker.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, can implement according to this with reference to specification word to make those skilled in the art.
This case proposes the high life oscillating plate for loud speaker of an embodiment, and it at least includes the combination of Fypro, bombax cotton and tossa.
In the above-described embodiments, with parts by weight, Fypro 100 parts, bombax cotton 24 ~ 25 parts, tossa 9 ~ 10 parts.The combination of different fiber not only can give play to respective advantage, can also work in coordination with and produce new modified effect, this three kinds of fibers of this case effectively can improve the structural strength of oscillating plate, moisture-proof and spring rate, increase the modulus of elasticity of oscillating plate, reduce the loss coefficient of oscillating plate, thus reduce the distortion of loud speaker, improve tonequality.
As another embodiment of this case, wherein, oscillating plate also preferably includes polyvinyl alcohol 3 ~ 4 parts.Polyvinyl alcohol can improve the modulus of elasticity of oscillating plate, but the addition of polyvinyl alcohol should be limited, if exceed preferred scope will cause the hydraulic performance decline of oscillating plate.
In the above-described embodiments, the thickness of oscillating plate is preferably 0.1 ~ 0.3mm.This thickness should be defined, if exceed preferred scope, is affected causing the tonequality of oscillating plate.
The modulus of elasticity of this case gained oscillating plate is 2300 ~ 2350, and loss coefficient is 0.034 ~ 0.036, and moisture-proof is good, and toughness is large, and structural strength is high, and fatigue durability is strong, has good anti-flammability and higher continuous useful life.
Although embodiment of the present invention are open as above, but it is not restricted to listed in specification and execution mode utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details.
Claims (4)
