Description
Technical field
The present invention relates to conductive material field, specifically a kind of sound system conductive transmission line.
Background technology
Sound system, refer here particularly to microphone, microphone signal amplifier, CD player, hard disc player, DVD player, phonograph, record
Sound machine, decoder（DAC）, sound card（ADC）, sound console, balanced device, effect device, prime signal amplifier, rear class power amplification
The system arbitrarily connected between the equipment such as device, audio amplifier and the equipment.Audio signal wire is mainly used in the audio signal of sound system
Electric current transmits；Horn wire is mainly used in the audio power electric current transmission between final-stage power amplifier and audio amplifier.Audio signal wire
It is weak current sound system transmission line, horn wire is heavy current transmission line in sound system.The rwo is commonly referred to herein as sound equipment
System conductive transmission line.
Since several years so far, sound system conductive transmission line, it has been substantially all using copper material（Including single crystal Cu and its
Big brilliant copper, polycrystalline copper etc.）As conductor material, have a small number of silver-plated using copper（Cast including Kufil）Or copper is gold-plated based on copper
" alloy " material.Copper material is widely used as a kind of sound system conductive transmission line.In other words, most loudspeaker so far
Line and signal wire be all using copper material as conductive material, it is only a small number of use based on copper material, copper supplemented by golden or silver is gold-plated,
The conduct sound system conductive transmission line such as copper is silver-plated, Kufil.
Why by copper or material based on copper as sound system conductive transmission line, being primarily due to copper has more
Outstanding conductance.In known metal conductance, the electrical conductivity of copper comes second（The resistivity of copper at 20 DEG C is
0.0172(µΩ.m)）.Conductance highest is silver-colored Ag, but because of silver-colored more expensive than copper or silver-colored conduct electric conductor in sound system application
Middle transmitted low frequency characteristic is good not as copper, and the sense of equilibrium of music frequency response is also be not as good as copper, so people's more more options copper material is made
For sound system conductive transmission line.
All the time, people's understanding one good and bad to the conductive transmission line performance of sound system only rest on conductance this
In single one physical characteristic, rarely have people bosom friend's acoustic system conductive transmission line performance antitypy and shock resistance in addition to conductance to be also present
Problem.
Conductance is the inverse of resistivity, and it can only illustrate electrical efficiency, is exactly the physical quantity that electric current passes through.Conductance is got over
Height, turn on angle is bigger, not much else.But electric conduction quantity can not illustrate the quality problem of its conduction state.
Generally, the use of sound system conductive transmission line keeps away not open the dynamic effects of two physical environments：One is electric current
Circuit environment dynamic effects, another is acoustic vibration environment dynamic effects.
First, in current loop environment static, that is, whole sound system not yet set up electric field it is non-energized in,
Conductive transmission line, power amplifier, frequency divider, loudspeaker etc. are in the electrical property state each isolated, once and system energization, conducting transmission
The sound systems such as line, power amplifier, frequency divider, loudspeaker just set up an electric field jointly, or else this electric field is each to maintain orphan
The static electric field of vertical electrical property state, but one is established jointly by equipment such as conductive transmission line, frequency divider, loudspeaker, power amplifiers
Mutually coordinated and conflicting dynamic electric field, i.e., by the coexistences such as conductive transmission line, frequency divider, loudspeaker, power amplifier altogether electricity
, the different electrical property of links is mutually coordinated and conflicting in this electric field, constitutes the special dynamic of current loop environment
State.For example, as conductive transmission line horn wire its between frequency divider can by the resistance value in frequency divider, inductance value,
The change such as the influence of the changes such as capacitance, frequency divider resistance value, inductance value, capacitance can influence horn wire electric conductor electric load
Change；On the other hand, in the loop, utilization of power magnetic energy makes loudspeaker voice coil drive vibrating diaphragm sounding, and voice coil loudspeaker voice coil and its vibrating diaphragm
Vibration can produce larger counter electromotive force, and these counter electromotive force can be superimposed in the horn wire i.e. electric field of conductive transmission line again,
It is that conductive transmission line produces larger electrical property effect to horn wire.
Secondly, it is influence of the acoustic vibration environment dynamic to conductive transmission line.Such as audio amplifier sounding, space residing for system and
Its whole sound field is all being vibrated.Vibration makes all links all impacted.Experience have shown that：If power amplifier, CD player, audio amplifier are changed
The pin nail of unlike material can hear different tonequality, tone color performance.Pin nail is as equipment load-bearing material and is not powered on, and be not entirely
In the electric field of system.Why pin nail can change system sounds effect for thatBecause the pin nail of different shape, unlike material
Resonant frequency it is different, its because by sound field vibration and forced vibration is conducted to the vibration frequency of stereo set with vibrational energy not
Together, the change of caused system tonequality, tone color.So the acoustic vibration in the same space can all produce to all circuits of system
Raw vibration effect.Horn wire is that conductive transmission line is no exception.In acoustic vibration environment, horn wire is that conductive transmission line can be because
External force effect produces piezo-electric effect：I.e. at conductor both ends（Contact point）Or the opposite electricity of polarization under certain frequency voltage conditions
Load, the electric load amount derive AC electromotive force in certain scale, and this electromotive force is probably to conductive transmission line electric field
Carry out resonance superposition, it is also possible to which resonance is successively decreased, and is disturbed with the deformation formed to conductive transmission line electric field --- sound coloration.
Based on above-mentioned two big influences, as sound system conductive transmission line under high-fidelity transfer performance requirement, it is conductive
Resistance performance with anti-seismic performance with regard to particularly important.So-called resistance performance, just it is resistant to the property of current loop environment dynamic effects
Energy；So-called anti-seismic performance is just resistant to the performance of acoustic vibration environment dynamic effects.
And the antitypy of sound system conductive transmission line and shock resistance and the physical and chemical composition and its close phase of characteristic of its conductor
Close.Related principal element is：Atomic number, electronic shell arrangement, atomic volume, relative atomic mass, electron configuration and resistance
Rate, electronegativity, ionization energy etc..Wherein, the atomic number electronics that produce much more, and polyelectron spinning track is got in electronic shell arrangement
More, for bigger its change in the electric field heavier with relative atomic mass of atomic volume with regard to smaller, electron configuration value gets over high ionization
Can be just smaller, the reproducibility of metal is better.Atomic number, electronic shell arrangement, atomic volume, relative atomic mass, electronics structure
Type equivalence is higher, and its antitypy and shock resistance ability are stronger, i.e., because by current loop environment dynamic effects and acoustic vibration ring
The probability of border dynamic effects is lower；Electronegativity, ionization energy value are lower, and metal reproducibility is better, to the stability of electric field environment
Ensured with order and more give power.
The maximum copper material sound equipment conductive transmission line of the above-mentioned current dosage being previously mentioned, in addition to conductance advantage, due to atom
Ordinal number, electronic shell arrangement, atomic volume, relative atomic mass, electron configuration equivalence are relatively low, and electronegativity and ionization energy value are higher,
Thus its antitypy and shock resistance are just poor, cause to be difficult to the music electric energy transmission flaws overcome：First, frequency range is narrower, low-and high-frequency
The extensibility of section is inadequate, and the extension of especially low-frequency range is relatively limited；Second, lacking unity and coherence, the various expressive objects in sound field stick
Paste, analytic ability are poor；Third, knot image force is poor, the lines sense of every kind of sound, the wide sense of rib are less apparent；Fourth, density is poor,
That is the plumpness of sound is poor.
In addition, being used from resistance to, copper material sound equipment conductive transmission line is nor preferably selection.Because copper easy oxygen in atmosphere
Change, usage time is longer, and resistivity can be higher.

It is all in above-mentioned background technology to solve it is an object of the invention to provide a kind of sound system conductive transmission line
Problem.
To achieve the above object, the present invention provides following technical scheme：
A kind of sound system conductive transmission line, including the electric conductor that insulated body wraps, the electric conductor are wrapped in insulator
