Abstract
The utility model discloses a keyboard type string pulling device and relates to a mechanism playing a piece of string instrument by use of a keyboard and an intermediate transmission device. The keyboard type string pulling device is mainly composed of keys, a mechanical arm, a pulley, strings, a string fixing column and a surrounding bow pulling silk thread, wherein the strings are arranged on the string fixing column through string holes, a nut and a tightener, which are arranged on the string fixing column; a spring is arranged below the string fixing column; the surrounding bow pulling silk thread consists of multiple bowstrings, is supported by a group of rollers and passes through the gap between the strings and the string fixing column; a support shaft is arranged at the middle section of each key; a support shaft is arranged at the middle section of the mechanical arm; one end of the support shaft is pressed at the tail end of each key, and the other end of the support shaft is provided with the pulley; and the pulley is arranged above the strings. Multiple groups of keys, the mechanical arm, the strings, the string fixing column and a resonant tank are combined together to form a multifunctional keyboard type bow pulling multi-string instrument. The instrument made by the keyboard type string pulling device is easy to learn and play.
Description
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.
The utility model content
The purpose of the utility model provides 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. 1 draws the schematic top plan view of tumtum for this keyboard-type;
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.
