Description

Erhu soft sound device

Technical Field

The utility model relates to an adhering device for changing original tone quality of urheen into soft tone by a player of urheen in national musical instruments, which is used for the urheen to be installed and used quickly when the soft tone is changed in a playing place.

Background

The Chinese fiddle is widely used at present, is suitable for the middle-low-grade erhu owned by general self-entertainment and self-entertainment crowds, and has slightly poor tone quality due to lower price; some players then use legs to hold the two ends of the barrel, and soften the original sound, which is called soft sound. However, the method of playing can cause discomfort and inelegant image, and the music can only be used for a short time.

Disclosure of Invention

The utility model provides a device which is light and can be quickly installed on a musical instrument support to replace the two legs to clamp the two ends of a musical instrument cylinder, and soft sound is obtained.

Analyzing according to a method that two legs clamp a piano tube, wherein the right leg applies proper pressure to the strings below the Chinese trumpet-shaped bridge at the snake skin end, and soft sound can be obtained; the utility model designs a set of devices, which can be attached to the musical instrument support and combined at the snake skin end of the musical instrument cylinder to form a flexible urheen; the parts are composed of: the device comprises a fixed seat, a manual nut, a bent arm, an adjusting screw and a string pressing plate; the fixed seat is adhered and fixed on the support for a long time, the bent arm is tightly connected on the fixed seat through a manual nut, an adjusting screw on the bent arm is adjusted to generate proper pressure, and a string pressing plate is applied to the section of strings below the bridge, so that the urheen obtains soft sound; when the device is used for playing soft sound, players can avoid the conditions of uncomfortable body, inelegant image and short-time use; when the soft sound is not needed, the manual nut is unscrewed, and parts except the fixed seat are dismounted.

Drawings

FIG. 1 shows a urheen soft sound device formed by attaching the set of devices to a support 11; the fixed seat 1 is fixed on the position of the piano support 11 by the wood screw 1-1, the bent arm 3 is fastened on the fixed seat 1 by the manual nut 2, the string pressing plate 5 presses the section of string 8 below the piano bridge 6 and is fixed by the adjusting screw 4 on the bent arm 3, and the attached urheen soft sound device is assembled. The bridge 6 is shown in the center of the snake skin end 7 of the barrel 10, and the shaft 9 is also shown in the figure.

Fig. 2 is a drawing of the parts of the kit after disassembly (outsourcing standard parts not shown) with the following names: a fixed seat 1; a manual nut 2; a bent arm 3 (expanded view) in which a countersunk-head screw 3-1 (a commercially available standard) is permanently fixed in place in the figure by welding or adhesive means; an adjusting screw 4; and pressing the chord 5.

Detailed Description

In the figure 1, a fixed seat 1 is permanently fixed at the bottom of a piano support 11 as shown in the figure 1 by 2 wood screws 1-1 (outsourcing standard parts), and the central line of a U-shaped opening is opposite to the central lines of two strings 8; inserting one end of the bent arm 3 with the countersunk head screw 3-1 into the fixed seat 1, enabling the countersunk head screw 3-1 to enter the U-shaped opening, and fixing by using the manual nut 2; the string pressing plate 5 presses two strings 8 below the bridge 6 and is fixed by 2 adjusting screws 4, thus completing the attachment and assembly of the urheen soft sound device.

After the assembly is finished, a player adjusts the strings to try to hear, and adjusts the position and the pressure of the chord pressing plate 5 by using the adjusting screw 4 according to the needs of the player to obtain soft sound.

The length of the string pressing plate 5 is not more than that of the bridge 6 after installation, the material is made of wood with the density lower than 0.75 g/cubic centimeter, and an arc groove with the width of 8 mm, the depth of two ends of 1 mm and the depth of the middle part of less than 1 mm is manufactured on one surface as a drawing; when the pressing strings 8 are installed, the groove surface or the smooth surface can be used; the player can also use other materials such as pencil eraser or cork to make the string-pressing plate 4 with a self-defined shape, which can also influence the formation of soft sound.

Except the string pressing plate 5, other parts are made of metal and can also be made of precious metal to improve the decorative artistic style; the bent arm 3 should have a certain elasticity.
