Abstract
The application discloses a fatigue-resistant long-service-life voice coil wire which at least comprises a combination of copper, aluminum and sliver, and further, the voice coil wire is prepared from 100 parts of copper, 37 to 38 parts of aluminum and 7 to 8 parts of sliver. According to the fatigue-resistant long-service-life voice coil wire, through improving the formula of a traditional voice coil wire, introduced modified metal effectively overcomes the defect of low sensitivity of a non-circular type loudspeaker, and through the improvement of the sliver, the voice coil wire has excellent high temperature resistance and fatigue resistance, so that the loudspeaker has certain plumpness in all bands, and distortion of the loudspeaker is greatly inhibited.
Description
Technical field
The present invention relates to a kind of acoustical material, be specifically related to a kind of endurance high life voice coil line for non-round loud speaker.
Background technology
Voice coil loudspeaker voice coil can be described as the heart of loud speaker, also be one of significant components of loud speaker, 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 loud speaker thus, and it is usually with the coiling in the cylindrical framework of the materials such as papery of circle enamelled wire, and whole voice coil loudspeaker voice coil divides two-layer or four layers of coiling, object makes the lead-out wire two ends of coil all towards drum paper side, and lead-out wire can be welded on bulging paper securely.
Traditional loud speaker is round, but along with the variation of electronic product profile, needs various loud speaker that can adapt to non-round electronic product, such as: the loud speaker of the shapes such as rectangle, square, ellipse.But according to prior art, round loud speaker is because of the characteristic of its symmetry, more convenient design and adjustment in tonequality, sensitivity etc., but after the shape of loud speaker is not round, due to affect tonequality, sensitivity factor too much, make to become very difficult and complicated to the adjustment of loud speaker, 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 used in prior art is pure copper wire or pure aluminum wire substantially, and certainly, the line of two kinds of materials has respective pluses and minuses, but when these two kinds of voice coil line are used for non-round loud speaker, 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 loud speaker, provide a kind of endurance high life voice coil line, it can make this loud speaker have higher sensitivity and plumpness, reduces the distortion of loud speaker.
Technical scheme of the present invention is summarized as follows:
A kind of endurance high life voice coil line, it at least includes the combination of copper, aluminium and silver.
Preferably, described endurance high life voice coil line, wherein, with parts by weight, copper 100 parts, 37 ~ 38 parts, aluminium, silver 7 ~ 8 parts.
Preferably, described endurance high life voice coil line, wherein, also comprises niobium 1 ~ 2 part.
Preferably, described endurance high life voice coil line, wherein, the diameter of described voice coil line is 0.1 ~ 0.2mm.
The invention has the beneficial effects as follows: this case is by improving the formula of traditional voice coil line, the modified metal introduced is effective overcomes the lower defect of non-round loudspeaker sensitivity, and, due to improvement that is silver-colored and niobium, voice coil line is made to have outstanding resistance to elevated temperatures and fatigue performance, make loud speaker all have certain plumpness at full frequency band, thus greatly inhibit the distortion 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 endurance high life voice coil line of an embodiment, and it at least includes the combination of copper, aluminium and silver.
In the above-described embodiments, with parts by weight, copper 100 parts, 37 ~ 38 parts, aluminium, silver 7 ~ 8 parts.
Aluminum steel is lighter than copper cash quality, and vibration efficiency is high, thus beautiful at high frequency, thoroughly, but not resistance toly to listen; The intensity of aluminum steel own is weak simultaneously, and adding, coiling in man-hour difficulty 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, and thus the signal transmission of copper cash own is uneven, can bring impact to the tonequality of loud speaker, especially for non-round loud speaker, affects larger.Therefore, the voice coil line that simple copper cash, aluminum steel or copper aluminium combine can not meet the tonequality requirement of non-round loud speaker, now needs in the component of voice coil line, to introduce other components to regulate tension force, the sensitivity harmony tonal density of voice coil line.
In the formula of above-mentioned voice coil line, the introducing of silver can work in coordination with the sound density improving voice coil line, and distortion is reduced; The resonance frequency of voice coil loudspeaker voice coil can be improved simultaneously, thus improve vibration efficiency and the sensitivity of loud speaker.In above-mentioned formula, three kinds of compositions are inseparable organic wholes, and its respective ratio 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 loud speaker.
As another embodiment of this case, wherein, on the basis of above-mentioned formula, also comprise niobium 1 ~ 2 part.Niobium can improve the Low ESR ratio of voice coil loudspeaker voice coil, and this makes when this voice coil loudspeaker voice coil is applied in non-round loud speaker, and the sound field of its low frequency is more natural and simple and honest, 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 100 ~ 110dB, and has good resistance to elevated temperatures and fatigue performance, high life, and use the tonequality full and natural of non-round loud speaker at full frequency band of this voice coil line, distortion is little.
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.
