Magic cube speaker

A magic cube speaker, comprising

• a magic cube module, the magic cube module comprising a liner, the liner comprising multiple sound transmission holes that connects inside and outside of the liner, splicing blocks installed on outside surface of the liner, and a cavity formed in an interior of the liner;
• a speaker installed inside the cavity, the speaker comprising a printed circuit board substrate, a controller mounted on the printed circuit board substrate, a short-range wireless communication module mounted on the printed circuit board substrate and electrically connected to the controller, a loudspeaker electrically connected to the controller, a battery electrically connected to the controller, the battery comprising a positive electrode and a negative electrode, and optionally an LED lighting module mounted on the printed circuit board substrate and electrically connected to the controller;
• a charging interface being fixedly mounted on one of the splicing blocks, the charging interface further comprising a positive electrode and a negative electrode and being matched with a charging plug;
• and
• a button mounted to one of the splicing blocks and electrically connected to the speaker,
• wherein the printed circuit board substrate of the speaker divides the cavity inside the liner into an upper cavity and a lower cavity;
• the battery is disposed in the lower cavity, and the loudspeaker is disposed in the upper cavity;
• the liner comprises an upper end, a first hemispherical cover covering the upper end, a lower end, and a second hemispherical cover covering the lower end, and the first hemispherical cover is bonded with the second hemispherical cover;
• the upper end of the liner comprises a first hole, a first tube body at upper end of the first hole and connecting to the liner through the first hole, and the lower end of the liner comprises a second hole, a second tube body at lower end of the second hole and connecting to the liner through the second hole;
• a first wiring passage is formed with interior of the first tube body, the first hole, and the inside of the liner, that connects to the upper cavity;
• a second wiring passage is formed with interior of the second tube body, the second hole, and the inside of the liner, that connects to the lower cavity;
• the splicing blocks comprises a first fixed splicing block, a second fixed splicing block, and a plurality of movable splicing blocks;
• the first fixed splicing block and the second fixed splicing block limit all movable splicing blocks, two adjacent splicing blocks are mutually coupled;
• each of the splicing blocks comprises a block body, an interlocking section connected to the block body, a groove between the interlocking section and the block body, and an outer surface of the interlocking section that matches contour of the outer surface of the liner;
• the first fixed splicing block is disposed outside the first tube body on the surface of the liner and connected to the first tube body, and the button is fit inside the block body of the first fixed splicing block;
• the second fixed splicing block is disposed outside the second tube body on the surface of the liner and connected to the second tube body, and the charging interface is fit inside of the block body of the second fixed splicing block;
• at least one of the splicing blocks comprises one or more sound passages, each of the sound passages comprises a sound inlet port, a sound outlet port, and a middle section between the sound inlet and outlet ports;
• the middle section is disposed in a hollow space inside the splicing block;
• the sound inlet port is disposed in the center of the interlocking section and connects to the middle section to the sound transmission hole;
• the sound outlet port is in a form of the sound transmission hole on a side wall of the splicing block or a plurality of micro holes arranged in an array on the surface of the splicing block;
• and
• a 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 in the form of the sound transmission hole on the side wall of the splicing block or the plurality of the micro holes arranged in the array on the surface of the splicing block.
