Abstract
The utility model discloses a kind of hollow de-noising signal transmission line, it comprises many cores and is coated on the outer quilt of insulation outside described core, it is characterized in that, described insulation is outer is provided with sound insulation and noise reduction layer by interior, and this sound insulation and noise reduction layer is multiple cavities evenly arranged around core.The beneficial effects of the utility model are: the utility model by being arranged cavity by interior outside insulation, effectively can reduce or eliminate the auscultation effect produced in sound wave, effectively can also reduce edge edge materials, save product cost, economical and effective, anti-noise yarn is set in cavity, and metal screen layer is set between heart yearn and the outer quilt of insulation, make signal transmssion line anti-noise ability of the present utility model better.
Description
Technical field
The utility model relates to electric wire field, is specifically related to a kind of hollow de-noising signal transmission line.
Background technology
Active noise reduction function is exactly produce the reverse sound wave equal with ambient noise by noise reduction system, is neutralized by noise, thus realizes the effect of noise reduction.Active mode denoise earphone adopts the wear-type that volume is larger to design with their major parts of the Dolby circuit contended with outside noise, the structures such as earplug cotton and earphone outer covering can be utilized to stop outside noise, carry out first round sound insulation, simultaneously also in order to have sufficient space mounting active noise reduction circuit and power supply.
Passive type noise cancelling headphone forms enclosure space mainly through surrounding ear, or adopts the acoustic materials such as silica gel earplugs to stop outside noise.Because noise is not through the process of Dolby circuit chip, generally can only high-frequency noise be intercepted, not obvious to low-frequency noise noise reduction.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of rational in infrastructure, excellent noise reduction effect, and the hollow de-noising signal transmission line that tensile strength is high.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of hollow de-noising signal transmission line, it comprises many cores and is coated on the outer quilt of insulation outside described core, and described insulation is outer is provided with sound insulation and noise reduction layer by interior, and this sound insulation and noise reduction layer is multiple cavities evenly arranged around core.
Described empty inwall is provided with yarn anti-noise layer.
Described core is arranged side by side between two, and comprises insulating barrier, signal transmitting layer and packed layer.
Described signal transmitting layer forms by many conductive filaments are stranded.
Described packed layer is elastic insulated line.
Between described core and the outer quilt of insulation, be also provided with a metal screen layer.
Described metal screen layer is the elastic telescopic webmaster that enamel covered wire and spandex are woven into.
The beneficial effects of the utility model are: the utility model by being arranged cavity by interior outside insulation, effectively can reduce or eliminate the auscultation effect produced in sound wave, effectively can also reduce edge edge materials, save product cost, economical and effective, anti-noise yarn is set in cavity, and metal screen layer is set between heart yearn and the outer quilt of insulation, make signal transmssion line anti-noise ability of the present utility model better.
Accompanying drawing explanation

Embodiment
Embodiment: see Fig. 1, the present embodiment provides a kind of hollow de-noising signal transmission line, it comprises many cores 1 and is coated on by 2 outside the insulation outside described core 1, and described insulation is outer is provided with sound insulation and noise reduction layer in 2, and this sound insulation and noise reduction layer is multiple cavities 3 evenly arranged around core 1.
Described empty 3 inwalls are provided with yarn anti-noise layer 4.
Described core 1 is arranged side by side between two, and comprises insulating barrier 5, signal transmitting layer 6 and packed layer 7.
Described signal transmitting layer 6 forms by many conductive filaments are stranded.
Described packed layer 7 is elastic insulated line.
Described core 1 and insulation outer by between 2, be also provided with a metal screen layer 8.
Described metal screen layer 8 is the elastic telescopic webmaster that enamel covered wire and spandex are woven into.
But the foregoing is only better possible embodiments of the present utility model, and be not used to limit to the scope of the claims of the present utility model, therefore the equivalent structure change that all utilization the utility model specifications and accompanying drawing content are done, be all included in protection range of the present utility model.
