Technical Field

The invention relates to the technical field of piano accessories, in particular to a cover buffer device of a grand piano.

Background

The piano is a keyboard instrument in Western classical music and is known as the king of the instrument. It is composed of 88 keys (52 white keys, 36 black keys) and a metal string sound board. The range of piano pitch ranges from a0(27.5Hz) to C8(4186Hz), and almost all tones in the tone system are covered, and the instrument is the instrument with the widest pitch range except for the pipe organ. Pianos are commonly used in important performance situations such as solo, duet, accompaniment, etc.

Grand pianos are a kind of pianos used for large shows or professional players. The grand piano adopts a design scheme that the strings are staggered, so that the height and the thickness are effectively saved. The piano string type piano hammer mainly comprises six parts, namely a piano string, a sound board, a bracket, a keyboard system (comprising black and white keys and a string-striking hammer), a pedal machine (comprising a mandril and a pedal) and a shell.

The top of the grand piano is provided with a big piano cover, when the grand piano is used, the piano cover needs to be turned up and opened from the piano body, and then the piano cover is supported by a support column for a certain angle. The sound board of the grand piano is arranged below the cast iron board, and when the piano is played, the sound is enhanced as long as the piano cover is opened, the played sound can immediately enter the ear, and each sound is easier to confirm. If the cover is not opened, the played sound is dull and stuffy, and good sound cannot be played.

Because grand piano is bulky, including the lid generally by the wooden material of heaviness, therefore when playing each time, when turning over the lid and retrieving the lid, need hold or hold the lid with strength, in addition when retrieving the lid in case can't hold, the lid can be heavy fall on the piano body, causes lid or piano body damage easily.
