Description
Technical field
The present invention relates to signal transmssion line, relate in particular to a kind of audio transmission line that can improve tonequality.
Background technology
The cable of the transmitting audio signal that uses in the music equipment, people generally are referred to as audio transmission line, and it is a cylinder, and integral body is linearly, and is as shown in Figure 1.The core of audio transmission line is a conductor 1; Be used for transmitting audio signal; The conductor 1 outside insulator 2 that covers like plastics or rubber, is the screen 3 that is made up of conductor outside the insulator 2; This screen 3 is used for isolated extraneous interference on the one hand, and the ground wire that is used to constitute audio signal on the other hand is the loop; Be insulation sheath 4 outside the insulating barrier 3, be used for inner each layer of protection, make audio transmission line wear-resistant, to increase the service life.
The defective that existing audio transmission line exists is, because there be " skin effect " or " kelvin effect " in conductor, when the audio signal of audio transmission line carry high frequency section; Electric charge is to the surface aggregation of conductor, and therefore, the signal of high band passes through the surface of conductors transmission basically; Low frequency signal is then through the conductor intermediate conveyor; Cause the transmission of high-frequency signal and low frequency signal unbalanced, the sound that audio signal is reproduced causes harmful effect, has reduced the tonequality of reproducing sound.
Summary of the invention
The objective of the invention is to propose a kind of audio transmission line, balanced with the transmission that guarantees high-frequency signal and low frequency signal, improve the tonequality of reproducing sound.
For realizing above-mentioned purpose, the invention provides a kind of audio transmission line, comprising: the input, at least one flat part and the output that connect successively; Be provided with opening on the center conductor two opposite edges of said flat part inside; Opening on said two limits is arranged in a crossed manner, and the length of said opening increases progressively to the side that said flat part links to each other with said output from the side that said flat part links to each other with said input successively.
This programme is through the opening of audio transmission line center conductor; The line length that the line length that makes center conductor medium-high frequency signal transmit is transmitted greater than center conductor medium and low frequency signal; Thereby balance the transmission speed of high-frequency signal and low frequency signal; And, recovered transmission of audio signals speed, thereby improved the tonequality of reproducing sound through increasing opening length successively.
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.

Embodiment
Audio transmission line can be through partly or entirely being set to be in the one or more square portion in the plane with center conductor; Make the top layer length of conductor greater than the centerline length of center conductor; Thereby guarantee high-frequency signal and low frequency signal transmission balance, improve the tonequality that audio signal is reproduced sound.
Fig. 2 is the sketch map of audio transmission line embodiment of the present invention, and Fig. 3 is the upward view of Fig. 2, and like Fig. 2, shown in 3, in the present embodiment, audio transmission line comprises input 61, flat part 62 and output 63; Flat part 62 can be arranged at the optional position between input 61 and the output 63; In the present embodiment; Distance between input 61 and the flat part 62 is greater than the distance between output 63 and the flat part 62; Be that flat part 62 approaches acoustic reproduction devices such as loud speaker, loudspeaker, reproduce the tonequality of sound with further assurance.Flat part 62 is a flat board, and flat part 62 inner center conductors should be tabular mutually, and in the present embodiment, flat part 62 is a rectangular flat; Correspondingly, flat part 62 inside center conductors are rectangular flat, and its length can be 1cm～30cm, and width can be 0.1cm～10cm; As shown in Figure 4, in the present embodiment, flat part 62 inner center conductor 8 length are 10cm; Width is 3cm, center conductor 8 be provided with opening on two limits up and down, the width of opening can be 1mm～2mm; Opening on two limits can be provided with 4～6 altogether up and down, in the present embodiment, is provided with 5 openings altogether; 3 openings in top are respectively first opening 81, the 3rd opening 83 and the 5th opening 85, following 2 openings; The opening that is respectively on second opening 82,84, two limits of the 4th opening is arranged in a crossed manner, from left to right promptly; Set gradually, first opening 81, second opening 82, the 3rd opening 83, the 4th opening 84 and the 5th opening 85, the length of these five openings increases progressively to the side that flat part 62 links to each other with output 63 from the side that flat part 62 links to each other with input 61 successively; Through opening is set, make the edge length on two limits up and down of center conductor increase greatly, promptly the transmission line of high-frequency signal increases greatly; The transmission line of center conductor medium and low frequency signal also increases to some extent simultaneously, but the transmission line of the high-frequency signal after circuit increases is also longer than the transmission line of low frequency signal, makes the speed of high-frequency signal reduce; Wait for the transmission of low frequency signal, guaranteed the transmission balance with low frequency signal, but therefore transmission of audio signals speed reduce; In order to recover audio signal speed, in the position near output, the length of opening constantly increases; Increase along with opening length; The width of the center conductor that audio signal is passed through reduces gradually, makes that the audio signal after the balance is quickened transmission, has recovered audio signal transmission speed; Thereby the audio signal of feasible transmission is reproduced sound signal better, has improved the transmission of audio signals quality.
In the foregoing description; Distance between the opening is successively decreased to the side that flat part 62 links to each other with output 63 from the side that flat part 62 links to each other with input 61 successively; Left side like center conductor 8 links to each other with input 61, and then the distance between the left side of center conductor 8 and first opening 81 is greater than the distance between first opening 81 and second opening 82, and the distance between second opening 82 and the 3rd opening 83 is greater than the distance of the 3rd opening 83 and the 4th opening 84; And the like; Distance between the right edge of the 5th opening 85 and center conductor 8 is the shortest, thus further balance the transmission speed of high-frequency signal with low frequency signal, improved the tonequality of reproduction sound.
Fig. 5 is the schematic cross-section of audio transmission line embodiment middle plateform of the present invention portion; Be filled with insulating cement 7 in center conductor 8 openings of flat part 62 inside; Firmly center conductor 8, avoid the audio signal of transmission in the vibration interference center conductor 8, effectively ensured the tonequality of reproducing sound.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
