Description

Automatic page-turning music stand

Technical Field

The utility model relates to the technical field of musical instrument auxiliary equipment, in particular to an automatic page-turning music stand.

Background

In daily music practice, music stands are not separated in music performance life, and the music stands can bring better learning experience to players through fixed music. The existing music stand is formed by connecting a metal support rod, a music disk above the support rod and a base below the support rod. The traditional music stand with the structure is fixed and inconvenient to move, and brings inconvenience to people when the place needs to be replaced. Secondly, when a player performs the music, the player often needs two hands to assist to finish the music perfectly, but the traditional music stand needs the player to make hands free to turn the music, and when the player performs the music on a table, the action of turning the music is also very abrupt, and the personal shape and the whole attractive appearance are affected. And because the traditional music rack does not have a telescopic function, when the heights of all people are different, the perception experience of all people is different, and the singing is influenced. Meanwhile, although the existing automatic page turning music score instrument can realize page turning of music score, the structure is too complex and the use is inconvenient. As disclosed in chinese patent CN109998278A, a portable scroll music stand is disclosed, and the patent application mentions in the background art that there are two forms of existing page turners and page turners: 1. paper sucking mode: the aerodynamic principle is adopted, and the atmospheric pressure difference is utilized to take paper, but the pneumatic mechanism and the electric mechanism are required to be designed in the mode, so that the mechanism is complex and huge in structure, the paper taking effect is poor after a long time, and the application effect is not ideal; 2. paper fixing mode: namely, a plurality of page turning rods are manufactured, and each page turning rod is responsible for turning a page of books.
