Description

A musical cube

Technical field

This application relates to the technical field of Rubik's Cube, in particular to a musical Rubik's Cube.

Background technique

The Magic Cube, also called Rubik’s Cube for short, was first invented in 1974 by Professor Erno Rubik of the Budapest School of Architecture, Hungary. Rubik's Cube is an extreme sport for hands. In a narrow sense, Rubik's Cube refers to the third-order Rubik's Cube. The shape of the third-order Rubik's Cube is usually a cube, made of flexible hard plastic. The racing game is to disrupt the Rubik's Cube and recover it in the shortest time. In a broad sense, Rubik's Cube can refer to various geometric objects that can be disrupted and restored by turning.

The existing Rubik's Cube has a single function, and some designs propose the idea of integrating the speaker function into the Rubik's Cube to expand the Rubik's Cube's functions and enhance its interest. However, please refer to Figure 1. The inner space of the Rubik’s Cube is equipped with multiple rotating shafts 1, which intersect at the center of the Rubik’s Cube, occupying a lot of space inside the Rubik’s Cube, making the remaining space inside the Rubik’s Cube of standard volume insufficient to install speaker components. . In some schemes, the Rubik’s cube is made larger in order to integrate the speaker function, which affects the operation of the user. In some schemes, the rotating shaft inside the Rubik’s cube is removed to make room for the speaker components. However, the Rubik’s cube loses its rotating function, so Room for improvement.
