The beneficial effects of the utility model reside in that, compared with the prior art, the utility model discloses a tung plate vibration principle realizes the tone quality requirement, changes the pitch change that distance between musical instrument bucket bore and peg and the musical instrument bucket can realize 2 octaves of low and 1 octave to made things convenient for the requirement of playing of south sound, opera songs, national characteristic musical instrument fan to two strings greatly.

Drawings

The present invention will be described in detail with reference to the accompanying drawings:

FIG. 1 is a schematic view of the structure of the present invention

The following are specific names of the labels in the drawings of the utility model: 1. a musical instrument rod; 2. a movable jack; 3. a musical instrument barrel; 4. an L-shaped string hook; 5. tung plates; 6. carrying out bridge connection; 7. a string bow; 8. a string; 9. A lower chord shaft; 10. and an upper chord shaft.

Detailed Description

As shown in figure 1, a novel two-string musical instrument consists of a musical instrument rod 1, a string bow 7 and a musical instrument barrel 3; the two strings can be divided into 2 octaves lower and 1 octave lower according to the size of the barrel 3 and the length of the piano rod 1; musical instrument bucket 3 constitutes for the equal open-ended wooden drum in both ends, and a face tung plate 5 is embedded in the close fit mode of an open end of musical instrument bucket 3, and its pronunciation principle is: the string bow 7 is pulled by a player to stir the strings 8, and the generated vibration is conducted to the barrel 3 through the bridge 6 and the tung plate 5 to generate resonance. An L-shaped string hook 4 is fixedly arranged on the outer wall of the port of the piano barrel 3, and the L-shaped string hook 4 is made of metal materials; tuning pegs (respectively defined as an upper tuning peg 10 and a lower tuning peg 9) are arranged on the right side of the upper end of the musical instrument rod 1 from top to bottom, and strings 8 are respectively fixed on the upper tuning peg 10 and the lower tuning peg 9; in the process of playing the string bow 7, the string bow 7 shuttles between the two strings 8, and the vibration of the tung plate 5 is driven by the vibration of the strings 8 to make a sound; the other ends of the strings 8 are respectively fixed on the L-shaped string hooks 4; a bridge 6 is placed on the surface of the tung plate 5, and the bridge 6 is used for placing strings 8 in the grooves of the bridge in a hanging mode, so that vibration and sound production are facilitated.

One side of the L-shaped string hook 4 is fixed on the outer wall of the bottom port of the barrel 3 through a screw, the other side of the L-shaped string hook is tightly attached to the surface of the tung plate 5, and the other side of the L-shaped string hook 4 tightly attached to the surface of the tung plate 5 is arranged in a straight line state with the bridge 6, so that the strings 8 are straightened linearly.

The diameter of tung plate 5 and the bore size of musical instrument bucket 3 suit to set up and form, and tung plate 5 imbeds on the bore of musical instrument bucket 3, can easily take off from musical instrument bucket mouthful department, and aim at makes the vibration pronunciation spacious, not vexed.

The upper and lower tuning pegs (10, 9) are installed by penetrating the piano rod 1.

The piano rod 1 is provided with a movable jack 2, and the movable jack 2 can slide up and down on the piano rod 1 to realize the fine adjustment function; the shape of the movable jack 2 can be trapezoidal, in order to ensure that the movable jack 2 is well matched with the piano rod 1, the joint between the movable jack 2 and the piano rod 1 is set into an arc shape consistent with the piano rod 1, so that the contact surface of the jack and the piano rod is matched; the movable jack 2 supports the string 8, on one hand, the jack 2 plays a sound fine adjustment role, and on the other hand, the jack 2 plays a three-dimensional supporting role for the string 8; an inner groove is arranged at the contact part of the string 8 and the movable jack 2 so as to facilitate the placing of the string 8 on the movable jack 2; the piano barrel 3 is formed by hollowing agave wood, and the diameter of the piano barrel 3 can be respectively set to be 19.6cm or 16 cm.

The distances from the upper chord 10 to the bottom of the barrel 3 are respectively 93cm and 80 cm.

The diameter of the two-string barrel 3 is 19.6cm, and when the distance from the upper chord axis 10 to the bottom of the barrel 3 is 93cm, the two strings are 2 octaves lower.

The diameter of the two-string barrel 3 is 16cm, and when the distance from the upper chord axis 10 to the bottom of the barrel 3 is 80cm, the two strings are lower by 1 octave.
