Abstract

The invention provides a keyboard type drawing strings device, relating to a mechanism of a playing stringed musical instrument by utilizing a keyboard and an intermediate gearing. The keyboard type drawing strings device mainly is composed of keys, an arm, a pulley, a string, a string fixing column and an encircled pulling wire. The string is fixed on the string fixing column through a string hole opened on the string fixing column, a string pillow and a tightener. A spring is provided under the string fixing column. The encircled pulling wire is composed of a plurality of bowstrings, is supported by a set of rollers, and goes through gap between the string and the string fixing column. An intermediate section of the key is provided with a back shaft. An intermediate section of the arm is provided with a back shaft, one end of the arm presses an end of the keys, and the other end of the arm is provided with a pulley which is above the string. A set of keys, the arm, the string, the string fixing column, and a resonator are combined together to form a 'multifunctional key type pulling strings piano'. The prepared piano is easy to learn and play.

Description

Keyboard-type draws tumtum

Technical field

A kind of keyboard-type draws tumtum, relates to a kind of mechanism that utilizes keyboard and intermediate gearing to play stringed musical instrument.

Background technology

Traditional stringed musical instrument exercise difficulty is big, and is very high to the dirigibility requirement of age and finger, also very high to player's music quality requirement, the bad grasp of accuracy in pitch, and the quantity of pronouncing simultaneously is few, and tone color is single.

Summary of the invention

The purpose of this invention is to provide a kind of device that utilizes keyboard to play string music.

This keyboard-type draws tumtum mainly by key, mechanical arm, pulley, string, string fixed leg and constitute around the silk thread of pulling the bow; String through the string hole of opening on the string fixed leg and be contained in capotasto and turnbuckle on the string fixed leg be contained in the string fixed leg above; Below the string fixed leg spring is housed; Form by some bowstrings around the silk thread of pulling the bow, support by one group of roller, and pass the gap between string and string fixed leg; Back shaft is equipped with in the stage casing of key; Back shaft is equipped with in the stage casing of mechanical arm, and the one of which end is pressed in the end of key, and the other end is equipped with a pulley, and pulley is positioned at the top of string.

This keyboard-type draws the playing method of tumtum: makes around the silk thread of pulling the bow through electronic or manpower (like pedal) and does gyration, or to-and-fro movement.Press key then, prize mechanical arm, make that the pulley on it is pressed on the string.String and string fixed leg move down, make string with contact around the silk thread of pulling the bow, and friction produces the effect that stringed musical instrument is played.After unclamping key, under the effect of spring, string and string fixed leg move up, and throw off around the silk thread of pulling the bow., be equivalent to bow here, on string, rub around the silk thread of pulling the bow.The keyboard of organizing, mechanical arm, string and string fixed leg are combined more, added that resonant tank just can constitute " multifunction key disc type pull the bow many strings qin ".

The qin that draws tumtum to make with this keyboard-type is easy to study and performance.The dynamics of utilizing the lever type mechanical arm can very trickle decision to stop reaches the purpose of trill.The move left and right keyboard can reach the purpose of glide.Sounding that can be single also can a plurality of sound sounding, many playing techniques, expressive force and abundant.

Description of drawings

Fig. 2 draws the schematic side view of tumtum for this keyboard-type;

Fig. 3 is the synoptic diagram of multi-grade lever formula mechanical arm.

Embodiment

Embodiment 1:

This keyboard-type draws tumtum mainly to be reached and constituted around the silk thread 8 of pulling the bow by key 1, mechanical arm 6, pulley 10, string 7, string fixed leg 5; String 7 through the string hole of opening on the string fixed leg 5 and be contained in capotasto 4 and turnbuckle 9 on the string fixed leg 5 be contained in string fixed leg 5 above; Spring 11 is housed below the string fixed leg 5; Form by some bowstrings around the silk thread 8 of pulling the bow, and one group of roller 14 supports, and pass the gap of 5 of string 7 and string fixed legs; Back shaft 2 is equipped with in the stage casing of key 1; Back shaft 3 is equipped with in the stage casing of mechanical arm, and the one of which end is pressed in the end of key 1, and the other end is equipped with pulley 10, and pulley 10 is positioned at the top of string 7; 12 and 13 is control handle among the figure, is used for spurring back and forth around the silk thread 8 of pulling the bow.

Embodiment 2:

Mechanical arm 6 among the embodiment 1, if long inconvenience assembling can be adopted many back shafts 3, parallel-series lever group together constitutes knockdown mechanical arm 6 (see figure 3)s.

Claims

1. a keyboard-type draws tumtum, is mainly reached by key, mechanical arm, pulley, string, string fixed leg to constitute around the silk thread of pulling the bow; It is characterized in that string through the string hole of opening on the string fixed leg and be contained in capotasto and turnbuckle on the string fixed leg be contained in the string fixed leg above; Below the string fixed leg spring is housed; Form by some bowstrings around the silk thread of pulling the bow, and one group of roller support, and pass the gap between string and string fixed leg; Back shaft is equipped with in the stage casing of key; Back shaft is equipped with in the stage casing of mechanical arm, and the one of which end is pressed in the end of key, and the other end is equipped with a pulley, and pulley is positioned at the top of string.

2. draw tumtum according to the described keyboard-type of claim, it is characterized in that mechanical arm can adopt many back shafts, parallel-series lever group together.
