Description

A Noiseless Sheng Seedling

technical field

The invention relates to a sheng seedling, in particular to a noiseless sheng seedling which can eliminate keystroke noise during playing.

Background technique

Sheng is one of the oldest wind instruments in China. It belongs to the hole-blowing and reed instruments in the reed instrument family, and is the originator of most existing reed instruments in the world. The sheng generally consists of a mouthpiece, a sheng bucket (that is, the sheng base connected to the mouthpiece, which acts as an air chamber), a sheng spring (installed at the lower end of the sheng seedling and inside the sheng bucket, and used as a vibration source to drive the gas in the sheng seedling to vibrate), the sheng Seedlings (many bamboo tubes or copper tubes of different lengths, the gas in which can vibrate to make music) and other parts, the player blows the gas into the Sheng bucket through the mouthpiece, and covers the openings on the Sheng seedlings with his hands ( Traditional type) or open the sound window hole (button type) on the Sheng seedlings by pressing the button (for metal material) to pronounce and play. The button-shaped Shengmiao generally has a loudspeaker tube on the outer jacket of the Shengmiao to enhance the sound produced. Sheng seedlings with buttons generally have a sound window hole on the upper end of the seedling tube, which communicates with the inner cavity of the seedling tube, and a spring installation hole is left at the lower end of the seedling tube for installing the Sheng spring, and on the side of the seedling tube Buttons are installed, one end of the button is a sound window hole cover for covering the sound window hole, the other end is a handle, the middle part of the button is hinged on the pillar, and the pillar is installed on the side of the seedling tube. This kind of button is relatively long for the relatively long seedling tube, and the button action will be transmitted slowly only through the middle pillar. For example, when one end of the handle is pressed, the metal button itself has a certain material toughness. The more obvious the long toughness is, the micro-bending of the key itself caused by this kind of toughness delays the response time of the key's rotation around the pillar, causing the opening of the sound window cover at the other end of the key to lag behind, and the pronunciation will also lag accordingly. The pronunciation cannot match the player's playing rhythm, and even the music will lose its original charm, which will make the player and the audience dissatisfied; at the same time, when the key is long, the sound window hole at the other end will be pressed after one end of the handle is pressed. The cover lifts relatively high, and when the cover of the sound window hole falls back, it will collide with the sound window hole with a loud sound. This kind of collision will produce certain interference as noise, especially disturbing the player's performance emotion. Invention patent CN105304070A discloses a button-relay type Sheng seedling, which divides the button into three sections to reduce the delay caused by the toughness of the material when a single button is delivered, and to reduce noise. In actual production, the length of the middle section of the three-section button is It is very short, and mainly plays the role of a transitional transmission. In fact, the sound window hole cover is raised by a relatively large range. Although the sound window hole cover is generally covered with a sponge layer for cushioning, it will still produce noise during actual operation. Cracking noise of some sound window covers and sound window holes.

Contents of the invention

The purpose of the present invention is to provide a noiseless Sheng seedling, which can further eliminate noise, and the key transmission is more flexible and smooth, which can better exert the player's performance skills and improve the user experience.

To achieve the above object, the present invention takes the following technical solutions:

A noiseless Sheng seedling, comprising a seedling tube, a hole for installing a spring spring is arranged at the lower end of the seedling tube, a sound window hole is arranged at the upper end of the seedling tube, and buttons are installed on the seedling tube, the buttons are composed of at least three equal lengths. Each key segment is connected in turn, and each key segment is installed on the column, and a reset shrapnel is installed on at least one key segment; a hole cover connecting rod is hinged on the shell of the sound window hole, and a sound window is installed on the hole cover connecting rod. The hole cover, the hole cover connecting rod is crimped at one end of the key section close to the sound window hole, the first sponge layer is connected on the lower surface of the sound window hole cover, and a double-sided adhesive layer is connected below the first sponge layer. A second sponge layer is connected below the adhesive layer, the first sponge layer and the second sponge layer have the same shape, and the area of the double-sided adhesive layer is smaller than the first sponge layer or the second sponge layer, and the second sponge layer on the outer edge of the double-sided adhesive layer There is a gap between the first sponge layer and the second sponge layer.

Preferably, the thickness of the first sponge layer is 1-2 mm, the thickness of the double-sided adhesive layer is 0.2-0.5 mm, and the thickness of the second sponge layer is 0.1-0.2 mm.

Preferably, the thicknesses of the ends of the two adjacent key segments are thinned and pin holes are left, and pin shafts are installed on the pin holes.

Preferably, the sound window hole is oval, and the first sponge layer, the double-sided adhesive layer and the second sponge layer are all oval.

In the above technical solution, the sound window hole cover is arranged on the connecting rod, and the sound window hole cover is raised by pressing the button to tilt the connecting rod, which is more flexible and lighter than directly connecting the sound window hole cover to the button At the same time, the sound window hole cover uses two layers of sponge, and the two layers of sponge leave a gap at the edge, so that when the second sponge layer contacts the sound window hole, it can be lifted up and contact with the first sponge layer to reduce the impact, and at the same time The specific thickness of the second sponge layer will further eliminate the noise when it is in contact with the sound window hole, and finally the whole case will not emit noise during performance, which can effectively improve the user experience.
