Description

The utility model relates to electrical engineering, in particular, to the design of audio (acoustic) cables designed to improve the quality of the transmitted audio signal in acoustic systems and used in consumer electronics for various inter-unit and component connections in audio equipment. In particular, within the framework of this utility model, cables are considered that are used to connect the audio components of stereo sound systems and 5.1 surround sound systems.

In the framework of the present invention, the construction of a conductive audio cable with minimal resistance and inductance along the length of the cable due to the reduction of the interconductor capacitance in the cable to almost zero due to the proximity of the positive and negative conductors is considered.

A known set of cables for connecting audio components, mainly a stereo system, comprising a connecting cable for the left channel, a connecting cable for the right channel and a connecting earth cable, and a minus cable, each of which includes a conductive core in an insulated sheath and connection terminals at the ends of the cables for connections with audio components in stereo mode (WO 03061343, H04S 3/00, H04S 3/02, publ. 2003.07.24).

From the same source, a set of cables for connecting audio components is known, mainly a stereo system, containing two connecting cables for the left channels, two connecting cables for the right channels, and a ground and minus connecting cable, each of which includes a conductive core in an insulated sheath and connecting cable lugs for connecting to audio components in 5.1 surround mode.

The specified known decision was made as a prototype for the first and second declared objects.

The technical result achieved is to improve the operational characteristics of the conductive cables and the sound quality of the speaker systems.

The technical result for the first embodiment is achieved by the fact that in the set of cables for connecting audio components, mainly a stereo system, containing a connecting cable for the left channel, a connecting cable for the right channel and a connecting cable for grounding and minus, each of which includes a conductive core in insulated sheath and connecting lugs at the ends of the cables for connection to audio components in stereo mode, the conductive core in each of these cables in made from at least two conductors that are twisted along the length of the conductors, and twisting is alternating equal lengths of twisting in a clockwise direction and twisting sections in a counterclockwise direction, having an equal number of turns in each twisting, and the ground and minus connecting cable includes an additional conductor, made in the form of a thin-walled pipe with an outer insulated sheath, inside which a conductive core is placed in an insulated sheath.

The technical result for the second embodiment is achieved by the fact that in the cable set for connecting audio components, mainly a stereo system, containing two connecting cables for the left channels, two connecting cables for the right channels and a ground and minus connecting cable, each of which includes a conductive a conductor in an insulated sheath and connecting lugs at the ends of the cables for connecting to audio components in 5.1 surround sound mode, a conductive core in each decree cables is made of at least two conductors twisted along the length of the conductors, and twisting is alternating equal lengths of twist in a clockwise direction and twist in a counterclockwise direction, having an equal number of turns in each twist, and the ground and minus connecting cable includes an additional a conductor made in the form of a thin-walled pipe with an outer insulated sheath, inside which a conductive core in an insulated sheath is placed.

For both versions, each conductive conductor can be made of at least two wire conductors that are twisted along the length in a direction opposite to the direction of twisting of the conductive conductors.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

According to this utility model, the construction of conductive cables, including audio (acoustic) cable, is considered. Such a current-carrying cable is intended for use in consumer electronics for various inter-unit and component connections of audio components in stereo sound systems 1 and surround sound in 5.1 format. More specifically, this cable is used to connect speaker units, which are subject to increased demands on the quality of the transmitted signal.

For both versions, the cable set for connecting the audio components contains a connecting cable 2 for the left channel, a connecting cable 3 for the right channel, and a connecting cable 4 for grounding and minus, each of which includes a conductive core 5 in an insulated sheath 6 and connecting terminals at the ends cables for connecting to audio components in stereo mode (figure 1). For a stereo system, this kit includes one cable for the left and right channels, and for a 5.1 surround sound system, the kit includes two cables for each channel. Figure 1 shows

In each such cable, the conductive conductor is made of 5 of at least two conductive conductors 7 twisted along the length of the conductors, and the twisting is an alternating equal length of twisting sections in a clockwise direction and twisting sections counterclockwise, having an equal number of turns in each twist (Fig. 2). For both versions, the connecting cable 3 of grounding and minus includes an additional conductor 8, made in the form of a thin-walled pipe with an outer insulated sheath 9, inside which a conductive core in an insulated sheath is placed (footnote in figure 1).

The interconductor capacitance located between the positive and negative conductive conductors strongly affects the passage of audio - video signals. The measuring indicator of the interconducting capacitance between the conductive wires of the positive (+) and negative (-) is so small that they never thought about its strong influence on all parameters of the characteristics known in audio - video equipment. The semiconductor inductance, located between the positive and negative conductors, has huge steps, measured in Henry, has a very significant and tangible effect on the passage of audio-video signals. The semiconductor resistance exists, and in ordinary (standard) conductors it is different, at a frequency of 100 Hz it is large (~ 350 kOhm), and at a frequency of 1 kHz it is small (~ 10 kOhm), but with the new technology for constructing a conductor, according to the present useful model, it is equalized and has the same performance both at a frequency of 100 Hz and at frequencies 1 kHz (at both frequencies ~ 6 ohms).

The highest sound signal transmission along the conductor directly depends not only on the resistance parameters along its length, as was previously considered (this parameter minimally affects the nature of the sound signal) and inductance (this parameter affects the low-frequency range not in the most basic component of the audible range and can be easily solved with using a reversed conductor) but, as it turned out, the most important electrical parameter affecting the most audible part of the sound signal perceived by the human ear in the range from 1 kHz to 20,000 kHz, is the indicator in pF of the interconducting capacitance and the interconducting inductance in the range from 30 Hz to 1 kHz, transmitting the signal (s) of the conductor between two parallel conductors - positive (+) and negative (-). The values of the interconductor capacitance in the digital indicators of pF and the interconductor resistance in μOhm are so minimal that they were never taken into account. But, as numerous laboratory measurements and experiments have shown, each value of one unit in the pF capacitance (unit of capacitance measurement) between the conductors has a huge difference in the final result of the audio or video signal. The capacitance indicators in 1 pF steps have a huge difference in values not only in the visual audible range of the human ear and the real visibility of the eyes visually, but also clearly reflected in the measuring sound graphs of the frequency response and on the test video grids. The lower the inter-conductor capacitance in pF and the inter-conductor resistance, the cleaner the audio or video signals, which is set both visually and in laboratory digital measurements. According to numerous measurement experiments, practice has shown that 100% of the conductive interconnect interconnect cables produced in the world have indicators from 50 pF to 300 pF of interconductor capacitance per linear meter of length, and from 10 μOhm to 350 μOhm depending on the frequency of measurements of the interconductor resistance. It is due to the minimum numerical indicators of the interconducting capacitance with a difference of 1 pF / meter linear and interconducting resistance that when passing an audio or video signal, people - listeners, music lovers and audiophiles hear a distinct difference in the sound of audio when comparing various connecting cables (interconnect and acoustic) , plus there is a difference in the quality of the video image on the same monitor connected by different video cables

After numerous laboratory work, it turned out: a huge indicator of interconductor inductance positively affects the audio signal - the higher the indicator, the better.

The design of the components (cables according to this utility model) of any audio-video equipment (electronics), the device device must have an arrangement of components and conductors so that all components of components, printed circuit boards, chips (microcircuits) and others ... are interconnected had a minimum inter-conductor capacitance (not more than 25 pF between + (plus) and - (minus), and were at distances from each other no closer than two centimeters, or located in insulating materials capable of eliminating the inter-wire Ikov capacity.

The number of component conductors of the main conductive core depends on its length. It is necessary to make a selection of the number of component conductors until the parameter of increasing capacitance, measured along the length, disappears in the main current-carrying core. As soon as the capacitance parameter disappears, the resistance and inductance parameters become minimal, and a further increase in the number of cores is pointless, since the remaining resistance and inductance parameters will not be globally improved. Further improvement is possible only with a change in the design of the component conductors.

The decrease in resistance along the length of the main cable is achieved by increasing the number of components of conductive conductors. The decrease in inductance along the length of the cable is achieved by reversing the components of the conductors that make up the main conductive core, as well as by increasing their number.

In general, a cable is a conductive core of at least two insulated conductors (conductive parts) located in an insulated sheath. Each conductor is made of a conductive wire (core) coated with an insulating varnished coating covered by an insulating fabric coating. In the said sheath (Fig. 2), both conductors are twisted along the length of the conductive core, while twisting is alternating equally long sections of twist in a clockwise direction (Scl.) And sections of twisting in a counterclockwise direction (Scl.), Having an equal number of turns in each twist. In each twist, the conductors are twisted with the same twisting force. The specified parameters of the conductive core are essential and determining for the process of charge transfer from one conductor to another. Thus, the core is a series of alternating sections, in one of which the conductors are twisted in one direction, and in the next section, the same conductors are twisted in the opposite direction with the formation of a “reverse” zone between the sections (Sreverse).

With this design, mutual cancellation of the twist of the interconductor capacitance formed in one section occurs with one sign equal in magnitude but opposite in sign to the capacitance formed in the next section.

According to the present utility model, the cable (FIGS. 3, 4) consists of a conductive core. Such a conductive core consists directly of a conductive part (conductor) and an insulator covering it. Figure 3 shows the implementation of a conductive core based on a seven-core conductor. This core consists of seven conductive conductors 7, which are all twisted in the direction of 10 in one direction. Moreover, each of the seven conductive conductors consists of, for example, eleven thin (for example, 0.179 mm diameter) wire conductors 11, which are all twisted together in a direction 12 opposite to the spin direction of the seven conductive conductors 7. Figure 3 shows a general twist diagram of the components core of conductive components. This principle of cable construction is used, starting with two conductive conductors and two wire conductors.

The sound signal passes through the cable along its upper contour (outer surface). It follows that if we expand the signal propagation zone in one line of the plane, we get the surface area along which the signal passes. From increasing the diameter of the cable, the conductor area for transmitting the audio signal increases. Therefore, the larger the diameter of the wire, the greater the transmission of the audio signal of the transmitting information. But inside the thick busbar of a large-diameter conductor, a lot of different spurious processes arise, where the secret of transmitting the audio signal is hidden to reproduce the correct, lively and clear sound. If the set of internal insulated conductors (Fig. 4), of which the main cable consists, is laid out in one plane and rolled into a pipe, then the sound signal transmission area will increase many times depending on the cross-section of the insulated conductors. All cores are located parallel to each other, which ensures minimal inductance, and the interconducting capacitance with this design is minimal or completely absent, which ensures the ideal passage of the audio signal. An ideal transmission of an audio signal by a conductor is provided by its design of thickness and number of conductive wires. In this useful model, the material of the conductors is not considered: for example, the purity of copper, in which all kinds of impurities from various components are always present, greatly affects the correct tonal balance of sound. The impurities that make up the copper conductor do not always affect the nature of the sound negatively, but depending on the constituents they can have a positive character,

This cable controls the audio signal by changing the parameters of resistance, inductance and capacitance along the length of the conductor. And also between the interconducting capacitance, resistance and inductance between the conductors. The cable can be used with various equipment and it is easier to configure it to a comfortable playback. Compared to conventional interconnect cables, the new progressive adjustable cables allow you to set up an ideally comfortable audio signal in any sound path individually for each listener.

This utility model is industrially applicable, as it can be implemented using technologies used in the manufacture of cables in the electrical industry.
