Problems solved by technology

[0002] In the past, traditional ethnic musical instruments used natural snakeskin as the sounding membrane of the speaker. Although the sound of snakeskin-made ethnic musical instruments is crisp and bright, it is very easy to be affected by dry or humid climates and cause noise or muffled sounds. In order to control the noise, the players , often set as "yin and yang strings", which can easily lead to inaccurate scales; resulting in unstable sound quality and timbre, and snake skin is an animal fiber, which is prone to moisture cracking, Collapse, mildew, etc.
[0003] In recent years, with the increasing awareness of wildlife protection, many individuals or units are actively exploring a "bionic skin" that can replace snake skin as the sounding membrane of the Huqin speaker. Bionic sounding membranes of various materials have sprung up like mushrooms. Although this kind of membrane overcomes the physical deficiencies of natural snake skin, the sound quality produced is not as natural, clear, and round as wild snake skin or python skin; it is also difficult to guarantee crisp, crisp, bright, Transparent and transparent stage effect

Embodiment 1

[0018] Use a piece of polyester cloth with a thickness of 1mm as the base weaving layer 1, and use two chemical raw material fibers or animal fur fibers or plant fibers with a diameter of about 0.8mm as the acoustic wires 2 and attach them laterally to the inner side of the base weaving layer 1. , place the polyphonic wire 2 so that the sound wave conduction diffused to the surroundings has "directionality", and then apply a bond coat 3 of cyanoacrylate polymer adhesive or epoxy resin glue, bond coat 3 It can be completely covered on the base braiding layer 1 or the sound-focusing wire 2 ; it can also be partially covered on the base braiding layer 1 or the sound-focusing wire 2 . The outer side of the base weaving layer 1 is covered with a layer of simulated snakeskin or python scales or a pattern layer 4 printed with a layer of simulated snakeskin or python scales, forming a base weaving layer 1, sound-focusing wire 2, bonding coating Layer 3 and pattern layer 4 are combined...

Embodiment 2

[0020] Use a piece of polyester cloth with a thickness of 0.8mm as the base weaving layer 1, and attach three chemical raw material fibers or animal fur fibers or plant fiber sound-focusing threads 2 with a diameter of about 0.6mm to the inner side of the base weaving layer 1 in a longitudinal direction. , place the sound-focusing wire 2 so that the sound wave conduction diffused to the surroundings has "directionality" and then coat a bonding coating 3 of a layer of cyanoacrylate polymer adhesive or epoxy resin glue, the bonding coating 3 can be completely It is covered on the base weaving layer 1 or the sound-focusing wire 2 ; it can also be partially covered on the base weaving layer 1 or the sound-focusing wire 2 . The outer side of the base weaving layer 1 is covered with a layer of simulated snakeskin or python scales or a pattern layer 4 printed with a layer of simulated snakeskin or python scales, forming a base weaving layer 1, sound-focusing wire 2, bonding The coati...

Embodiment 3

[0022] A piece of polyester cloth with a thickness of 0.6mm is used as the base weaving layer 1, and 5 chemical raw material fibers or animal fur fibers or plant fiber acoustic threads 2 with a diameter of about 0.5mm are attached to the inner side of the base weaving layer 1 in irregular directions. Place the sound-focusing wire 2 so that the sound wave conduction diffused to the surroundings has "directionality" and then coat a layer of cyanoacrylate polymer adhesive or epoxy glue with a bonding coating 3, the bonding coating 3 can be It is completely covered on the base weaving layer 1 or the sound-focusing wire 2 ; it can also be partially covered on the base weaving layer 1 or the sound-focusing wire 2 . The outer side of the base weaving layer 1 is covered with a layer of simulated snakeskin or python scales or a pattern layer 4 printed with a layer of simulated snakeskin or python scales, forming a base weaving layer 1, sound-focusing wire 2, bonding The coating 3 and t...

Abstract

The invention discloses an artificial musical instrument sounding membrane, which comprises a substrate braid, at least one sound collecting line adhered to the substrate braid and an adhesive coating coated on the substrate braid and the sound collecting line; and the substrate braid, the sound collecting line and the adhesive coating are integrally compounded to form a flat surface or pitted surface sound membrane with thickness of 0.05-2.5mm. In the sounding membrane, the sound collecting line is arranged in the substrate braid, so that sound wave conduction diffused around has directivity and sound waves of a plurality of fibers are superposed to produce a resonance phenomenon on the surface of the sound membrane; in addition, a brittle substrate effect formed after the adhesive coating is dried produces resonance in a sound box; thus the sound membrane has more natural, clear and smooth sound quality and tone, particularly has an attractive stage effect such as crisp, clear and permeable in the aspect of a two-stringed bowed instrument with a high register.

Description

technical field [0001] The invention relates to a musical instrument sounding membrane, in particular to a bionic sounding membrane simulating snake skin or python skin, especially a sounding membrane mainly used for sound boxes of national musical instruments such as Jinghu, Jingerhu and Sanxian. Background technique [0002] In the past, traditional ethnic musical instruments used natural snakeskin as the sounding membrane of the speaker. Although the sound of snakeskin-made ethnic musical instruments is crisp and bright, it is very easy to be affected by dry or humid climates and cause noise or muffled sounds. In order to control the noise, the players , often set as "yin and yang strings", which can easily lead to inaccurate scales; resulting in unstable sound quality and timbre, and snake skin is an animal fiber, which is prone to moisture cracking, Collapse, mold and other phenomena. [0003] In recent years, with the increasing awareness of wildlife protection, many ...
