Contrabass

Abstract

The invention relates to a contrabass. The contrabass comprises a headstock, a finger plate, strings, a body and a stay wire plate. The headstock is connected on the upper portion of the body through the finger plate, the stay wire plate is connected on the lower portion of the body, and the plurality of strings are connected between the headstock and the stay wire plate. The body comprises a barrel body, an upper cover, a lower cover, a pronouncing middle plate and a bridge. The barrel body is cylindrical, and the upper end and the lower end of the barrel body are respectively packaged through the upper cover and the lower cover. The pronouncing middle plate is arranged in the barrel body along the central axial line of the barrel body and divides the barrel body into two voice boxes, the strings and the pronouncing middle plate are located on the same plane, resonance holes communicating the two voice boxes are formed in the pronouncing middle plate, a plurality of hollowed-out hole in geometric modeling are formed in the barrel body of any voice box, a voice hole communicating the inside and the outside of the barrel body is formed in the barrel body, the lower portion of the bridge extends into the barrel body through the voice hole and is vertically erected on the pronouncing middle plate, and the upper portion of the bridge vertically bears the plurality of strings. The contrabass is simple and compact in structure, convenient to use, long in service life, good in high-pitch, middle-pitch and low-pitch voicing effect, and strong in adaptability.

Description

technical field [0001] The invention relates to a stringed musical instrument, in particular to a stringed double bass. Background technique [0002] Stringed instruments are an important branch of the musical instrument family. Stringed instruments rely on mechanical force to make the tensioned strings vibrate and produce sound. From the way of sounding, they are mainly divided into bowed stringed instruments and plucked stringed instruments. [0003] Among the existing bowed and stringed musical instruments, the musical instruments for playing the bass part include the cello and the bass leather. Among them, the large bass is very inconvenient to carry and play; and the bass leather is processed by cutting a section of bamboo tube. Cover a piece of snakeskin on the other end of the circular surface to form a sound box, install a bamboo bow, match two pegs and two strings, and install a movable horse bridge to form an erhu instrument, which only has two erhu instruments.

[0003] Among the existing bowed and stringed musical instruments, the musical instruments for playing the bass part include the cello and the bass leather. Among them, the large bass is very inconvenient to carry and play; and the bass leather is processed by cutting a section of bamboo tube. Cover a piece of snakeskin on the other end of the circular surface to form a sound box, install a bamboo bow, match two pegs and two strings, and install a movable horse bridge to form an erhu instrument, which only has two erhu instruments. Strings, the number of tones that can be drawn is limited, and the range is narrow, so it cannot be made into a series of large, medium and small musical instruments with complete high, middle and bass parts in the strict sense.
