1-2, the utility model discloses a string capable of passively balancing internal structure uniformity, which comprises a string core 1, wherein a gain layer 2 is arranged on the outer surface of the string core 1, and the gain layer 2 is wound on the outer surface of the string core 1 by metal wires; the outer surface of the gain layer 2 is wound with a noise reduction layer 3, the outer surface of the noise reduction layer 3 is provided with a fastening layer 4, and interlayer filling paste 5 is filled and smeared among the chord core 1, the gain layer 2, the noise reduction layer 3 and the fastening layer 4.

Wherein, the string core 1 is composed of single or multiple metal wires, chemical fiber wires or silk, when the string core is composed of multiple monofilaments, a single silk bundle is formed by twisting multiple monofilaments without twisting; thereby ensuring the fracture resistance strength thereof. In this embodiment, a single steel wire, chemical fiber or silk may be used to twist the rope, wherein a plurality of steel wires form the steel rope; the strand amount of the steel wire is between 3 and 9 so as to ensure that the formed chord core 1 has better circumferential roundness, so that the gain layer 2 can be wound and wrapped better.

And a gain layer 2 is wound on the outer surface of the string core 1 to increase the specific gravity of the whole string, so that the tension at standard pitch can be increased, the maximum vibration can be obtained, the resonance between the body and the resonance box can be increased, and the sound volume can be increased. In this embodiment, the gain layer 2 may be formed by rolling a high specific gravity alloy wire such as gold, silver, copper, etc. to a flat shape and winding the wire around the outer surface of the chord core 1.

In addition, because the strings vibrate to obtain the required sound volume and bring too much high-frequency sound, the strings need to be reduced and suppressed; according to the utility model, the noise reduction layer 3 is arranged, and the noise reduction layer 3 is formed by untwisting and doubling a plurality of chemical fiber filaments or silk and is wound outside the gain layer 2. Therefore, the noise reduction layer 3 formed by the chemical fiber wires or the silk can be used for restraining metal noise brought by the string core 1 and the gain layer 2, providing more times of sound, enriching the resonance of strings and providing better tone feeling.

The fastening layer 4 is formed by rolling the composite chemical fiber monofilament and winding the composite chemical fiber monofilament outside the noise reduction layer 3 to form the fastening layer 4, in this embodiment, the winding needs multiple layers, the string core 1, the gain layer 2 and the noise reduction layer 3 are tightly wrapped and fixed through the elasticity of the composite chemical fiber monofilament, and the purpose of same-frequency resonance can be achieved when the whole string vibrates.

The interlayer filling paste 5 is filled and smeared among the chord core 1, the gain layer 2, the noise reduction layer 3 and the fastening layer 4, so that the interlayer filling paste 5 can enter into fine gaps among layers in the subsequent grinding and pressing process, and each layer can form resonance when vibrating, so that the noise caused by the resonance of each layer is reduced; and the interlayer filling paste 5 is always present in each layer of windings, and can be continuously moved into the gaps newly appeared due to the vibration of the strings and the gaps appeared due to the aging, fracture, corrosion and the like of the windings of the strings in the subsequent use of the strings, so that the uniformity of the internal structure of the strings, the balance of the density and the resonance at the same frequency can be ensured. In this embodiment, the interlayer filling paste 5 is made of viscous oil extraction grease, and can also perform an adhesive-like function by the characteristic of being viscous, but the non-fixed adhesive does not prevent the mutual displacement of the layers in the vibration use of the string. And if the interlayer filling paste 5 is excessively filled, the surface can be gradually oozed along with pressing, so that the lubrication of the outer surface of the strings is ensured, the abrasion of fingers of a player is protected, the friction damage of the strings between the strings and the strings is reduced, and the noise generated by the strings, the strings and the fingers due to drying is reduced.
