Problems solved by technology

The drum produced in this way has the following problems: First, the wood itself has a strong vibration reduction ability, and the drum cavity made of pure wood has a poor echo effect and a relatively wooden sound. Although the sound is thick enough, the loudness is not enough, and the drum sound penetrates Secondly, compared with metal, the density of wood is lower, and the molecular arrangement is not tight enough. Even after many times of polishing, there are still many potholes and pores on the surface of wood, and these potholes and pores accelerate The attenuation of the sound affects the resonance; in addition, the cowhide that has been naturally air-dried has the problems of thicker drums, dull drums, poor toughness and easy cracking.
[0004] In addition, the drum body of the traditional drum is formed by splicing multiple plates. Because the plates are not directly spliced ​​tightly enough, the drum cavity is not airtight enough, and the sound is easy to leak out. not long life

Embodiment 1

[0039]A method for manufacturing a large drum, which includes the following steps:

[0040]Step 1. Soak the peach and red cones in lime water for 1-2 days, then take out to dry; soak the dried peach and red cones in water for 5 months, then take out and dry; The dried peach wood and red cones are fired, so that a carbonized layer of 1 cm is formed on the surface of the wood, and the carbonized layer is removed to obtain the core material; the core material is cut into pieces, then soaked in resin for 15 days and dried to obtain dried peach wood and To dry red vertebral wood, cut dry peach wood to 1.5 meters long, 8 cm wide, and 5 cm thick peach planks, and cut dry red vertebral wood to 1.5 meters long, 8 cm wide and 3 cm thick.

[0041]Step 2: Mix silica particles with a particle size of 50 microns and wood wax oil in a mass ratio of 1:10 to obtain an immersion liquid, and place the peach wood and red lamina in the immersion liquid for 30 days. Take out the natural air-dry, use the peach ...

Embodiment 2

[0052]A method for manufacturing a large drum, which includes the following steps:

[0053]Step 1. Soak the peach and red cones in lime water for 2 days, then take out to dry; soak the dried peach and red cones in water for 6 months, then take out and dry; then dry them The peach wood and red cones are fired to form a 2 cm carbonized layer on the surface of the wood. After removing the carbonized layer, the core material is obtained; the core material is cut into pieces, then soaked in epoxy resin for 20 days and dried to obtain dry peach wood and The thickness of the peach plank is 5 cm, the width is 8 cm; the thickness of the red vertebrae is 3 cm, the width is 8 cm, and the length is 1.2 meters.

[0054]Step 2: Mix silica particles with a particle size of 0 microns and wood wax oil in a mass ratio of 1:10 to obtain an immersion liquid, and place the peach wood and red lamina in the immersion liquid for 30 days. Take out the natural air-dried, peach plank as the main plate and red verte...

Abstract

The invention discloses a large-scale drum manufacturing method, comprising: 1. soaking peach wood and red cone wood, drying them, and burning them to obtain core materials; sawing the core materials into peach wood boards and red vertebrae boards; After soaking, the red lumbar boards are naturally air-dried. The peach wood boards are the main board, and the red lumber boards are the sub-boards; 3. Use the main board and the sub-boards to form the drum body and close the gap between the boards; 4. The drum body is covered with a metal layer; Soak the cowhide to get the bloodless cowhide; 6. Air-dry the bloodless cowhide to get the half-dried cowhide; 7. Dry the half-dried cowhide to get the dried cowhide; 8. Leave the dried cowhide to stand to get the drum head; device; 10. Stretching the drum skin to form a drum surface; 11. Inserting hoops into the two ends of the drum body to obtain a strong drum. The stretching device of the present invention is designed to stretch the cowhide, and the stretched cowhide has better elasticity, higher toughness, strong vibration, loud sound, and reduces cracking.

Description

Technical field[0001]The present invention relates to the technical field of musical instruments, and more specifically, the present invention relates to a method for manufacturing large drums.Background technique[0002]The Mashan Drum is a type of Zhuang drum. Today, the Mashan Drum has been officially included in the Guangxi Zhuang Autonomous Region-level Intangible Cultural Heritage Protection List. It is also known as the "Mashan Three Treasures" along with the Zhuang’s poles and the Zhuang’s three-voice folk song. "The number of people participating in the study and performance of the drums continues to rise. Mashan Drums are used in grand style performances, so the drums are required to be grand and vigorous, strong in creating momentum, and spread far.[0003]The traditional method of making drums is to cut hard wood into plates, polish the plates and splice them together to form a drum body, and use cowhide to air-dry and set it on both ends of the drum body to form a drum skin...
