Embodiment approach

[0031] In these two implementations, a sound hole 200 is provided on the side of the horizontal box body facing the high-pitched area, which can ensure the sound to be emitted smoothly, maintain a clear tone, and avoid sound muffled.

[0032] The second embodiment of the present invention is as Figure 4 , 5 , shown in 6 and 7, the top surface of the box body 2 is arc-shaped, and the height towards the side of the upright piano 1 low range is greater than the height of the side towards the high range of the upright piano 1; The detachable connection device is a detachable hinge 22, the side one of the box body 2 is connected with the upright piano through the detachable hinge 22, and the side two of the box body 2 is connected with the upright piano 1 through a hasp 21 . In this way, the box body 2 can be directly opened relative to the piano body, forming a refraction surface facing the audience.

[0033] As a further optimization of this embodiment, two sound guide plates...
