Abstract
The invention discloses a moisture-resistant paper cone for a loudspeaker. The moisture-resistant paper cone at least comprises a combination of polyvinyl chloride, polyester fiber and lignin. In the scheme, a material formula of a conventional paper cone is improved, and modified fiber is introduced, so that the defect of poor moisture resistance of a paper cone in the prior art is overcome. Moreover, the fiber and the lignin are improved together, so that the paper cone has superior structural strength, corrosion resistance and fatigue resistance, and the loudspeaker can keep relatively high fullness for a long time on a full band. Thus, distortion of the loudspeaker is restrained greatly, and the tone quality of the loudspeaker is enhanced.
Description
Technical field
The present invention relates to a kind of acoustical material, be specifically related to a kind of moisture-proof cone for loud speaker.
Background technology
Cone is one of major part of loud speaker, has conclusive impact to the performance of loud speaker and tonequality.In loud speaker, can produce sharp pounding in magnetic field after voice coil loudspeaker voice coil connects audio signal, voice coil loudspeaker voice coil is fixed on cone, and the vibration of voice coil loudspeaker voice coil drives the vibration of cone simultaneously, and cone vibration forces air to vibrate, thus sounds.
Mainly there is following defect in conventional loudspeakers cone 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 moisture-proof cone 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 moisture-proof cone for loud speaker, it at least includes the combination of polyvinyl chloride, polyester fiber and lignin.
Preferably, the described moisture-proof cone for loud speaker, wherein, with parts by weight, polyvinyl chloride 100 parts, 58 ~ 60 parts, polyester fiber, 15 ~ 16 parts, lignin.
Preferably, the described moisture-proof cone for loud speaker, wherein, also comprises polyvinyl alcohol 7 ~ 8 parts.
Preferably, the described moisture-proof cone for loud speaker, wherein, the thickness of described cone is 0.1 ~ 0.3mm.
The invention has the beneficial effects as follows: this case is by improving the material prescription of traditional cone, the modified fibre introduced is effective overcomes the defect that in prior art, cone moisture-proof is lower, and, due to the common improvement of fiber and lignin, cone 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 moisture-proof cone for loud speaker of an embodiment, and it at least includes the combination of polyvinyl chloride, polyester fiber and lignin.
In the above-described embodiments, with parts by weight, polyvinyl chloride 100 parts, 58 ~ 60 parts, polyester fiber, 15 ~ 16 parts, lignin.Lignin can extract from various timber.The combination of polyester fiber and lignin not only can give play to respective advantage, can also work in coordination with and produce new modified effect, this three kinds of components of this case effectively can improve the tensile strength of cone, moisture-proof and spring rate, increase the modulus of elasticity of cone, reduce the loss coefficient of cone, thus reduce the distortion of loud speaker, improve tonequality.
As another embodiment of this case, wherein, cone also preferably includes polyvinyl alcohol 7 ~ 8 parts.Polyvinyl alcohol can improve the modulus of elasticity of cone, but the addition of polyvinyl alcohol should be limited, if exceed preferred scope will cause the hydraulic performance decline of cone.
In the above-described embodiments, the thickness of cone is preferably 0.1 ~ 0.3mm.This thickness should be defined, if exceed preferred scope, is affected causing the tonequality of cone.
The modulus of elasticity of this case gained cone is 2350 ~ 2430, and loss coefficient is 0.033 ~ 0.035, and moisture-proof is strong, and toughness is high, and structural strength is large, has good fatigue resistance and anti-flammability.
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)
1., for a moisture-proof cone for loud speaker, it at least includes the combination of polyvinyl chloride, polyester fiber and lignin.
