Technical Field

[0001] The present application relates to the technical field of musical instruments, and in particular to a bamboo membrane musical instrument drum body and a bamboo membrane musical instrument. Background Art

[0002] Membranous instruments are an important part of the modern musical instrument system, and they play a role in leading the ensemble and controlling the beat during performance. Closed membranous instruments rely on the tensioned tympanic membrane to vibrate and produce sound. The tympanic membrane and the drum wall form an air chamber resonance cavity, and the airtightness of the air chamber directly affects the sound effect of the drum. Traditional membranous instruments are usually made of hardwood, such as red sandalwood, rosewood, etc., and can be divided into one-piece or split types according to the structure. One-piece membranous instruments are made by milling a whole piece of wood. A large amount of wood resources are wasted during the processing process, and the wood will shrink and swell severely when the humidity changes. Split membranous instruments are formed by gluing or bundling multiple pieces of wood. The vibration generated during performance may cause the failure of the glued surface or the loosening of the bundling structure, shortening the service life of the instrument. Utility Model Content

[0027] Reference Figure 1 and Figure 2 An embodiment of the present application provides a bamboo membrane musical instrument, including a bamboo membrane musical instrument drum body 1, a drum membrane 2 wrapped around the left and right sides of the drum body 1 and stretched, and a strap 3.

[0028] The drum body 1 of the bamboo membrane musical instrument includes a bamboo tube, which is obtained by radial sawing of a giant dragon bamboo stalk with a diameter of 25 cm. The bamboo tube includes a bamboo node structure 11 and a bamboo node diaphragm 12 located in the bamboo node structure 11. The bamboo node diaphragm 12 is located at 1 / 3 of the length of the bamboo tube. The bamboo node diaphragm 12 divides the bamboo tube into a high-pitched resonance chamber 13 and a low-pitched resonance chamber 14. When playing, clapping the eardrums of different resonance chambers will produce musical sounds of different tones, enriching the expressiveness of the instrument.

[0029] In addition, bamboo's natural multi-scale pore structure and sparse inside and dense outside gradient structure give bamboo instruments good acoustic properties, and the hollow structure of bamboo stalks also facilitates the processing of membrane instruments.

[0030] In order to prevent the bamboo membrane musical instrument drum body 1 from cracking or affecting the acoustic properties due to shrinkage and swelling caused by changes in environmental humidity, the outer surface of the bamboo tube in the embodiment of the present application retains bamboo green. Therefore, the wax and silicon dioxide contained in the bamboo green help prevent the bamboo material from cracking or affecting the acoustic properties due to shrinkage and swelling.

[0031] After the left and right end surfaces of the bamboo membrane instrument drum body 1 are sanded smooth with a grinding wheel, the eardrum 2 is stretched and wrapped thereon, and then the eardrum is glued to the bamboo tube with adhesive to form a closed structure. The smooth edge of the drum body helps to improve the fit of the eardrum.

[0032] In order to facilitate playing during marching, the bamboo membrane musical instrument drum body 1 can be detachably connected with a strap 3. Specifically, a screw hole 4 is provided on the bamboo tube, and a screw 5 passes through the strap 3 and is screwed into the screw hole 4 to fix the strap 4 to the bamboo membrane musical instrument drum body 1. The connection between the screw 5 and the screw hole 4 is filled with adhesive or paraffin to enhance airtightness. Thus, the bamboo membrane musical instrument with a strap enables the performer to fix the drum to the side of the body, which is conducive to playing during marching.

[0033] In addition, refer to Figure 3 and Figure 4 In order to facilitate the fixed-position performance, in some embodiments, the bamboo membrane musical instrument further includes a fixed support seat 6 supported at both ends of the bamboo membrane musical instrument drum body 1.
