Magic Cube Speaker with Nested Acoustic Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magic cube speakers that combine the functionality of a Rubik's Cube toy with a Bluetooth speaker are not feasible due to size constraints, as the volume of the speaker is too large to fit inside the cube, and there is insufficient space for batteries, leading to poor sound quality and difficulty in charging and controlling the device.
Innovation Solution
An integrated magic cube speaker design featuring a hollow liner with a cavity and splicing blocks, a speaker with a printed circuit board, battery, and a charging interface, along with a button for control, allowing the cube to function as both a toy and a speaker while maintaining movability and efficient charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the volume of the Bluetooth speaker is reduced to fit inside the magic cube, then the device can be made portable and playful, but the sound quality deteriorates
Solution Approach 1:
The speaker unit, battery, and control components are nested inside the hollow cavity of the magic cube structure. The splicing blocks enclose the speaker while maintaining the classic magic cube exterior, allowing the speaker to be contained within the toy's traditional form factor.
Solution Approach 2:
The magic cube is divided into functional segments: the hollow liner cavity houses the speaker and battery, while the splicing blocks provide structural integrity and classic toy functionality. This segmentation allows independent optimization of each component's position and size.
2Volume of moving object
If the magic cube size is reduced to maintain traditional dimensions for playing, then portability is improved, but there is insufficient space to fit the battery and speaker
Solution Approach 1:
The battery and speaker are nested within the hollow cavity formed by the liner and splicing blocks. This nested structure maximizes the use of internal space while maintaining the external dimensions of a traditional magic cube.
Solution Approach 2:
The design utilizes the three-dimensional hollow space efficiently by positioning components in different spatial zones within the cavity, optimizing volume utilization without increasing external dimensions.
3Adaptability or versatility
If the speaker and battery are integrated inside the magic cube blocks, then the device becomes a unified toy-speak er, but control and charging become difficult
Solution Approach 1:
The charging interface and control buttons are extracted from the internal cavity and positioned on the external surface of the splicing blocks. This allows users to easily access and operate the device without disassembling the magic cube structure.
Solution Approach 2:
The splicing blocks serve dual functions: maintaining the classic magic cube playability and providing access points for speaker control and charging operations, unifying toy and electronic functions.
4Volume of moving object
If the speaker is placed inside the magic cube, then the device achieves compact form factor, but sound transmission to the outside is poor
Solution Approach 1:
The splicing blocks are designed with specific acoustic properties and positioning to optimize sound transmission from the internal speaker to the external environment, with certain blocks potentially having sound transmission windows or optimized material properties.

AI summary
Magic cube speaker with charging stand, charging block, and methods for controlling the same, comprising a magic cube module having a liner with a cavity inside and splicing blocks installed on surface of the liner, a speaker inside the cavity, a charging interface, and a button mounted to the splicing block. The splicing block comprises sound passages formed by a sound inlet port, a sound outlet port, and a middle section between the sound inlet and outlet ports. A first sound transmission channel is formed by the cavity inside the liner, the sound transmission holes, the sound inlet port, the hollow space inside the splicing block, and the sound outlet port, and a second sound transmission channel is formed by the cavity inside the liner, the sound transmission holes, the sound inlet port, the hollow space inside the splicing block, and the plurality of the micro holes.
