Abstract
The utility model provides a keyboard type string device and relates to a component used by a musical instrument. The keyboard type string device consists of a key, a string press arm, a string stretching frame, a straight bow and a transmission belt. A string is installed on the string stretching frame by a string frame and a string plucking device; one end of the string stretching frame is provided with an arc spring sheet; and the other end thereof is provided with a wheel that is pressed on a slideway. The string press arm is a long pole with a bent front portion; and the lower end of the bending portion is arranged on the string stretching frame. The front end of the string is installed below the rear end of the string press arm. The straight bow that is installed on the transmission belt is arranged under the string and is perpendicular to the string at the horizontal plane. After multiple groups of strings, string press arms, and the string stretching frames are combined together, a keyboard type string instrument is formed. According to the utility model, the provided keyboard type string device enables the playing effect of the keyboard to be enhanced.
Description
Technical field
A kind of keyboard-type draws the string device, relates to the parts of using on a kind of musical instrument.
Background technology
General keyboard can only be used for playing straight sound.Thereby so that playing effect is comparatively single, such as piano.
General stringed musical instrument can only pronounce by two sounds simultaneously simultaneously, thereby so that and sound effective value comparatively single, such as violin.
The utility model content
The purpose of this utility model provides a kind of device that utilizes keyboard to play string music.
It is by key that this keyboard-type draws the string device, press string arm, the string frame that stretches tight, directly bend and driving-belt consists of; Stretch tight and by string frame and string tensing device string is housed on the string frame, the one end is equipped with the camber spring leaf, and the other end is equipped with wheel, and wheel is pressed on the slideway; Pressing the string arm is the stock of anterior bending, and the lower end of its dogleg section is positioned on the string frame that stretches tight, and presses the horizontal component of string arm can mutually intersect in the space with the string frame that stretches tight, and changes direction and uses; The front end of key is contained in the below, rear end of pressing the string arm; Straight bow is contained on the driving-belt, and is positioned at below the string, and is vertical on surface level with string.
During performance, press key, prize and press the string arm, the string frame that will stretch tight is depressed, so that string contacts with straight bow.Straight bow moves reciprocatingly under the effect of driving-belt, has namely finished the process of drawing string.When pressing key, the move left and right key drives the string frame double swerve that stretches tight by pressing the string arm, or presses firmly that key moves reciprocatingly and the string tension that stretches tight that changes the string frame that stretches tight, and changes the vibration frequency of string, can form the effect of gentle string.The to-and-fro movement of driving-belt can be passed through drive disk assembly, controls with pedal.After unclamping key, under the effect of spring leaf, string breaks away from straight bow.Key, pressure string arm, the string frame that stretches tight organized are combined the stringed musical instrument that just can consist of keyboard-type more.This keyboard-type draws the string device can increase the playing effect of keyboard music.
