Abstract
The invention discloses a voice coil wire with a long service life for a non-circular loudspeaker. The voice coil wire at least comprises a combination of copper, aluminum and zirconium. According to the voice coil wire disclosed by the invention, the formula of the traditional voice coil wire is improved, the introduced metals effectively overcome the defect of low sensitivity of the non-circular loudspeaker, moreover, due to the improvement of the zirconium, the voice coil wire has excellent high temperature resistance and fatigue resistance, and the loudspeaker has certain plumpness at all frequency bands, thus greatly inhibiting the distortion of the loudspeaker.
Description
Technical field
The present invention relates to a kind of acoustical material, be specifically related to a kind of high life voice coil line for non-round loudspeaker.
Background technology
Voice coil loudspeaker voice coil can be described as the heart of loudspeaker, also be one of significant components of loudspeaker, voice coil loudspeaker voice coil, after conduction, within magnetic field, is that the bright left hand rule of Buddhist produces motion, drive the motion of drum paper, voice coil loudspeaker voice coil is the driving element of loudspeaker thus, and it is conventionally with the coiling on the cylindrical skeleton of the materials such as papery of circle enamel-covered wire, and whole voice coil loudspeaker voice coil divides two-layer or four layers of coiling, object is to make the lead-out wire two ends of coil all towards drum paper one side, and lead-out wire can be welded on bulging paper securely.
Traditional loudspeaker is round, but along with the variation of electronic product profile, needs various loudspeaker that can adapt to non-round electronic product, such as: the loudspeaker of the shapes such as rectangle, square, ellipse. But according to prior art, round loudspeaker is because of its symmetrical characteristic, more convenient design and adjustment at the aspect such as tonequality, sensitivity, but after the shape of loudspeaker is not round, too much owing to affecting the factor of tonequality, sensitivity, make the adjustment of loudspeaker become very difficult and complicated, now not only need to consider oscillating plate, also will consider the impact on audio such as voice coil loudspeaker voice coil, bullet ripple.
The voice coil line using in prior art is pure copper wire or pure aluminum wire substantially, and certainly, the line of two kinds of materials has pluses and minuses separately, but in the time that these two kinds of voice coil line are used for non-round loudspeaker, its sensitivity becomes lower, and distortion is more serious.
Summary of the invention
For the deficiencies in the prior art part, the object of the invention is to for non-round loudspeaker, a kind of high life voice coil line is provided, it can make this loudspeaker have higher sensitivity and plumpness, reduces the distortion of loudspeaker.
Technical scheme of the present invention is summarized as follows:
For a high life voice coil line for non-round loudspeaker, it at least includes the combination of copper, aluminium and zirconium.
Preferably, the described high life voice coil line for non-round loudspeaker, wherein, and in weight portion, 100 parts of copper, 45～46 parts, aluminium, 3～4 parts of zirconiums.
Preferably, the described high life voice coil line for non-round loudspeaker, wherein, also comprises 2～3 parts, magnesium.
Preferably, the described high life voice coil line for non-round loudspeaker, wherein, the diameter of described voice coil line is 0.1～0.2mm.
The invention has the beneficial effects as follows: this case improves by the formula to traditional voice coil line, the modified metal introduced is effective has overcome the lower defect of non-round loudspeaker sensitivity, and, due to the improvement of zirconium and magnesium, make voice coil line there is outstanding resistance to elevated temperatures and fatigue performance, make loudspeaker all there is certain plumpness at full frequency band, thereby greatly suppressed the distortion of loudspeaker.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
This case proposes the high life voice coil line for non-round loudspeaker of an embodiment, and it at least includes the combination of copper, aluminium and zirconium.
In the above-described embodiments, in weight portion, 100 parts of copper, 45～46 parts, aluminium, 3～4 parts of zirconiums.
Aluminum steel is lighter than copper cash quality, and vibration efficiency is high, thereby beautiful at high frequency, thorough, but resistance to listening not; The own weak strength of aluminum steel simultaneously, adding, the difficulty that winds the line man-hour is large; Weight of copper wire is large, and copper cash center is applicable to transmission medium and low frequency signal, and surface is applicable to transmitting high-frequency signal, thereby the signal transmission of copper cash own is inhomogeneous, can bring impact to the tonequality of loudspeaker, especially for non-round loudspeaker, affects larger. Therefore, the voice coil line that simple copper cash, aluminum steel or copper aluminium combines can not meet the tonequality requirement of non-round loudspeaker, now need in the component of voice coil line, introduce tension force, sensitivity harmony tonal density that other components regulate voice coil line.
In the formula of above-mentioned voice coil line, the introducing of zirconium can be worked in coordination with the sound density that improves voice coil line, and distortion is reduced; Can improve the resonant frequency of voice coil loudspeaker voice coil, thereby improve vibration efficiency and the sensitivity of loudspeaker simultaneously. In above-mentioned formula, three kinds of compositions are inseparable organic wholes, and its ratio separately should be limited, and exceeds this scope, will cause the hydraulic performance decline of voice coil loudspeaker voice coil, and cannot meet the tonequality requirement of non-round loudspeaker.
As another embodiment of this case, wherein, on the basis of above-mentioned formula, also comprise 2～3 parts, magnesium. Magnesium can improve the Low ESR ratio of voice coil loudspeaker voice coil, and this makes in the time that this voice coil loudspeaker voice coil is applied in non-round loudspeaker, and the sound field of its low frequency is nature and simple and honest more, and distortion is less.
In addition, the diameter of voice coil line is preferably 0.1～0.2mm.
The sensitivity of this case gained voice coil line is 105～110dB, and has good resistance to elevated temperatures and fatigue performance, and high life uses the non-round loudspeaker of this voice coil line in the tonequality full and natural of full frequency band, and distortion is little.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in description and embodiment, 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.
