Description

Technical Field

[0001] The utility model relates to the technical field of piano practice auxiliary equipment, in particular to a piano practice clock punching machine. Background Art

[0002] Online education is already an indispensable education model in the future, but it is a very special education field for the music and art education industry. Teachers must teach by hand and pass on knowledge by word of mouth so that students can truly master the hand shape, strength, breath use and rhythm of music when playing the piano; it takes a long time of practice to master the skills of playing; practicing the piano is a very boring and repetitive thing for learners. Because students' time is very precious nowadays, their families cannot provide tutoring, and factors such as travel costs cause students to only go to institutions to study 1-2 times a week. In the traditional music education process (teaching, learning, and practicing), it is difficult for teachers to control students' practice at home, which often leads to: students do not practice and make no progress, but parents blame the teacher for not being able to do it well. Therefore, the emergence of piano clock-in machines has solved the above problems very well.

[0003] The piano practice time clock can record the students' practice status, provide certain guidance, and feed back the data to the teacher, which is beneficial to the students' practice effect at home. The piano practice time clock needs to be placed next to the piano when in use. In order to avoid taking up too much space, its shell is designed to be flat, but this makes its placement less stable, so it is usually necessary to configure a counterweight at the bottom to ensure that it can be placed stably when in use. However, such a design will increase the weight of the overall product, which is not conducive to the flexible use of the product. Utility Model Content
