BACKGROUND OF THE INVENTION
1) FIELD OF THE INVENTION
[0001] The invention herein relates to high-fidelity sound system equipment and accessories,
specifically an improved structure audio signal cable suitable for full frequency
range (high, medium and low frequency) applications.
2) DESCRIPTION OF THE PRIOR ART
[0002] Signal transmission requirements have become higher because of the greater fidelity
and sensitivity of currently available high fidelity audio system equipment. However,
the signal cables utilized to convey alphanumeric pulse or audio frequency, alternating
current signals involve transmission principles that are much more complex than that
of direct current transmission. In addition to the resistance encountered by electricity
flowing through the conductors and the generation of a magnetic field, there is skin
effect occurring between high and low frequencies as well as phase distortion. To
transmit a signal via a conductor at a balanced and total true-fidelity, acoustic
frequency range (20Hz to 20kHz or wider), the design of the conductive material is
extremely painstaking. Only this way can an amplified signal sound like the original
when replayed through a loudspeaker.
[0003] Good signal cables should support fine dynamics, separation, and rich overtones as
well as presence and musicality, but most importantly, it must have a very high degree
of balance. Since balance is the most essential factor of high fidelity acoustics,
when full-range balance is poor, this results in various problems. For example, insufficient
bass makes people feel that music is muted and diluted. Conversely, when bass is excessive,
sound becomes too dense and even burdensome. Sound becomes cold when midrange is lacking
and overly warm when too much is heard. At the same time, overall definition is decreased,
resulting in acoustic dispersion, sound alteration, and positional inaccuracy problems.
When treble projection is inadequate, music becomes depressive, monotonous, and spatially
confined, while the reverse situation results in a presentation that is too bright
and lively. Interfacing robust cabling with other equipment involves a certain degree
of difficulty; in conventional signal cables, skin effect is a challenging problem
in that it is a common cause of distortion and adversely affects signal transmission.
SUMMARY OF THE INVENTION
[0004] Therefore, the primary objective of the invention herein is to provide a full frequency
range, improved structure audio signal cable capable of solving the technological
problems that would allow the output of different frequency band signals (i.e., treble,
midrange, and bass), while also preventing phase differences.
[0005] To achieve the said objective, the invention herein utilizes the following technological
means: The audio signal cable of the present invention is comprised of arrayed solid
and tinsel wire conductors; after each of the conductors are insulated, they are placed
into a surrounding insulation
[0006] The solid conductors of the invention herein are of a circular and a flat, thin shape
as well as differing larger and smaller diameters and, furthermore, disposed in unequal
quantities.
[0007] The solid conductors of the invention herein are of differing larger diameters, wherein
the diameter of the larger solid conductors is two to three times that of the smaller
solid conductors.
[0008] In the audio signal cable of the invention herein, there are different diameter larger
and smaller and, furthermore, circular and flat-, thin-shaped cables as well as tinsel
wires disposed in unequal quantities that are covered to form cables, with filler
elements disposed in the space between the cables and the insulation.
[0009] To compare the invention herein with the prior art, each cable is a structure consisting
of a plurality of parallel, separate, and insulated conductors, wherein the cables
thereof are thin and light, and most importantly have exceptionally low inductance
and capacitance to convey tone color clearly and accurately. Furthermore, since high
frequency signals are conveyed at faster speeds along metal surfaces and arrive first,
while low frequency signals travel along the center of the conductors and arrive later,
the smaller diameter tinsel wires are twined to increase distance and enlarge their
surface area to reduce skin effect for better high frequency transmission, with the
larger diameter conductors enabling the rapid conveyance of low frequencies. As such,
the present invention achieves the synchronous phasing of high and low frequency signals.

DETAILED DESCRIPTION OF THE INVENTION
[0011] First, the advantages of tinsel wire for amplified music broadcasting is explained.
As is well known, for any conductor carrying an electric current, the electric current
transmitted is affected by capacitance, inductance, and impedance inherent in the
conductor itself. Such capacitance, inductance, and impedance inevitably causes phase
shifts and frequency attenuation of the electrical signal, resulting in transmission
losses. Moreover, high frequency signals and rich harmonic waves are easily dissipated
by the low quality physical characteristics of the cable and insulative covering,
noticeably reducing acoustic detail and timbre as well as other high fidelity components.
To remedy such situations, in addition to improving the material quality of the cables
and utilizing a relatively thin, flat material to achieve greater optimization within
the bounds of practicality, the surface area of the conductor is enlarged to offset
the skin effect that becomes more serious as the conductive efficiency of a conductor
is raised. The best means of increasing conductor surface area is to utilize ultra-thin
copper foil as the material; superior tinsel wire has a transmission impedance of
only 2.5 ohms, which is approximately 1/50 that of a conventional rod-shaped material;
as such, tinsel wire has low transmission impedance, meaning that it has even higher
transient current conductivity, better transmission speed and load control capability,
and a signal transmission phase shift of nearly zero, ensuring no signal phase shifting
and noticeably enhancing sound position, focus, and separation.
[0012] Referring to FIG. 1, larger solid conductors 1 and their insulation 2 comprise cables
a, smaller solid conductors 3 and their insulation 4 comprise cables b, and tinsel
wires 5 and their insulation 6 comprise cables c; after the cables a, b, and c of
differing quantity and size are bundled into a multiple core conduit 7, an insulation
8 is placed around the outer extent of the multiple core conduit 7 to form a multiple
core signal cable 9 and 10, filler elements 11 are disposed laterally along the multiple
core signal cables 9 and 10 to form a multiple core composite cable 12, following
which insulation 13 is placed around the multiple core composite cable 12 to complete
the first embodiment cable 14 of the invention herein.
[0013] Referring to FIG. 2, the cross-sectional drawing of another embodiment of the invention
herein, this variation is based on the first embodiment of the invention herein and
additionally includes a thin, flat conductor 15 that is cross-sectionally rectangular
which becomes a cable following the placement of insulation 16 around it; after the
cables a, b, c, and d of differing quantity and size are bundled into a multiple core
conduit 7, an insulation 8 is placed around the outer extent of the multiple core
conduit 7 to form the multiple core signal cables 9 and 10, filler elements 11 are
disposed laterally along the multiple core signal cables 9 and 10 to complete a multiple
core composite cable 12, following which an insulation 13 placed around the multiple
core composite cable 12 to complete the second embodiment cable 14 of the invention
herein.
[0014] The said conductor refers to any conductive material; conductive cables are typically
available in range of certain metals, but can be constructed of any suitable metallic
material such as solid copper or multi-stranded copper cable, metal-based coatings
containing silver, aluminum, iron, and other metals as well as alloys and other different
formulations; the conductor can also be a non-metallic compound having conductive
properties.
[0015] The said insulation, also known as a dielectric, refers to a material suitable for
cable insulation such as polyethylene, polypropylene, fluoropolymer, crosslinked polyethylene,
rubber, and other similar materials; many insulation materials also contain more than
one type of additive such as a flame retardant agent and a mildew-proofing agent.
[0016] The said larger solid conductors 1 and smaller solid connectors 3 have physical diameters
that are determined through actual testing; in the embodiments herein, the diameter
of the larger solid conductors 1 is two times that of the smaller solid conductors
3.
[0017] The multiple core signal cables of the invention herein consists of a plurality of
parallel, separate, and insulated conductors, wherein the cables are thin and light
and most importantly have exceptionally low inductance and capacitance to convey tone
color clearly and accurately. The acoustic characteristics of the thin, flat conductor
include clarity, high definition, rich detail, tighter low frequency response, and
enhanced livecabless; furthermore, the insulating of each conductor prevents interference
between different conductors, thereby avoiding distortion losses in the original signal.
[0018] A signal audio cable constructed using varying combinations of multiple tinsel wire,
flat solid conductors, and round solid core conductors of varying gauges with individual
insulation. Unique invention is that these different conductor types handle specific
frequency ranges differently and can be combined and optimized size, number and type
for best performance in various audio applications. An unique cable type has been
invented using combinations of these different conductor types. The tinsel wire is
constructed with special core and dielectric materials for further optimization, and
it minimizes sonic degradation caused by skin effect, thus yielding better high frequency
performance. Because low frequencies are compromised with tinsel wire, solid bass
conductors are used, thus balancing the frequency response. Flat conductors also handle
midrange frequencies with greater accuracy, and these are used for this purpose. Specifically
selected round conductor gauges are also used for the midrange to give proper balance
between the bass and treble spectrums. Different gauge round conductors appear to
emphasize particular frequency ranges, and can be selected to flatten frequency balance.
The unique combination of tinsel wire and selected round and flat solid conductors
gives better full range frequency balance and sound quality. The composite construction
yields superior frequency balance and response accuracy than can be obtained by using
constructions consisting of only one conductor type. The reasons for this are not
clearly understood, but it appears that the different types of conductors are superior
in certain frequency ranges. By combining conductors that each appear to be superior
in the treble range, the bass range, and the midrange, a superior full range cable
results. This construction is applicable to any type of audio signal.

structure audio frequency cable herein, the said embodiment shall not be construed
as a limitation on the patented scope and claims of the present invention and, furthermore,
all equivalent adaptations and modifications based on the technological spirit of
the present invention shall remain protected within the scope and claims of the invention
