Description

A kind of wire structure of specializing in musical instrument sound

The utility model relates to electric wire or cable, especially specializes in the electric wire of musical instrument sound use or the technical field of cable.

The traditional electric wire of specializing in musical instrument, sound equipment class or cable generally adopt the coaxial shape transmission structure of inner wire+insulator medium+outer conductor, be used for transmitting audio signal, but at the scene in the use, usually need to move continually, thereby produce the electrical noise that is disturbing the normal audio electric signal, have a strong impact on the transmission of signal, the technological deficiency of such electric wire or cable fails to solve well always.So when this kind electric wire or cable are used for electronic musical instrument or sound equipment, when microphone is connected, are difficult to provide high-resolution, low noise or muting transmitting audio signal.Repeatedly test and analyze according to us, confirm that this electrical noise derives from the conductor of electric wire or cable and the trickle space between the insulator medium, in use, between the conductor and between conductor and the medium mutually mutual friction produced due to the static, in order to remove the static of this variation, want again not change under the condition of basic structure of such electric wire or cable, between inner wire and medium or outer conductor and medium, the conductive materials that one deck can be eliminated its static and electric field is set, thereby the electrical noise that electric wire or cable produce in using moving process is eliminated, satisfied the technical requirement of high-quality transmission sound signal.

The purpose of this utility model is to provide a kind of high definition, low noise, and structure is simple again, the wire structure of being convenient to produce of specializing in musical instrument sound.

The technical solution of the utility model is such.This specializes in the wire structure of musical instrument sound, it includes inner wire, insulation course, outer conducting layer and outer jacket thereof, inner wire, insulation course, outer conducting layer and outer jacket are coaxial configurations, and be inner wire, insulation course, outer conducting layer and outer jacket successively from inside to outside, it is characterized in that between described insulation course and the outer conducting layer outer semiconducting layer being arranged.

Interior semi-conductive layer is arranged between above-mentioned inner wire and the insulation course.

The electric wire of the present utility model or the construction of cable since between inner wire and the insulating dielectric layer or/and to be provided with the conductive materials that can eliminate static and electric field between outer conducting layer and the insulating dielectric layer be semi-conductive layer, can remove electric wire or cable in use conductor and fricative static of insulating dielectric layer and electric field effectively, reduce and the removal electrical noise, so that high definition, low noise or muting transmitting audio signal to be provided.And structure still coaxial configuration basically, production technology changes few, convenient production, and cost increases few, and the connection that is fit on electronic musical instrument, microphone, the sound equipment is used.
