This updated 2.0 version is a significant improvement over the 1.0 version!
The 2.0 version has a built-in amplifier board, supporting Bluetooth 5.3, left and right dual channels (main and sub-speakers), adjustable RGB light board, OLED display screen, etc.
Due to the high cost of production this time, the PCB will not be open-sourced for now. The model file is still open-source as usual. If you need to use the PCB kit for this project, please feel free to purchase it from my Bilibili Workshop. Thank you for your support!
The model has also undergone significant changes compared to the 1.0 version, adding a diaphragm at the back. Combined with the sealed enclosure, the bass effect can be significantly improved.
In addition, this upgrade extensively uses multi-color printing. If you have a multi-color printer, you can achieve better aesthetics, especially for the RGB light part. I have uploaded the side panel configuration files for multi-color printing. I will explain the reasons for printing this way in detail below:
As shown in the image above: The side panel requires a total of 3 colors. Purple, white, and black.
You can change the purple color according to your preference, while the black and white parts are fixed colors. The white hexagon corresponds to the location of the built-in LED beads, with a thickness of 0.5.
There are two reasons for using multi-color printing here. Firstly, it provides a more textured appearance, and secondly, it ensures that there is no light leakage. Of course, if you don’t have a multi-color printer, you can choose not to print these hexagons. They are independent in the model file, and you can delete them.
The black part also solves the light leakage problem. Many printing materials have a certain degree of light transmittance. Using black can significantly reduce light transmittance, making each LED bead shine brighter and cleaner. At night, the entire side panel will not glow. If you don’t have a multi-color printer, you can try replacing the consumables midway to achieve this. The thickness of the purple layer is 1mm, and I have also segmented it in the model. If you ignore light leakage, using single-color printing is also perfectly fine.
Below is the light guide plate
The light guide plate uses 100% infill directly. PLA is recommended. It is recommended to use PLA with a slightly transparent texture, not pure white, but not translucent PLA either. I used white PLA from Landu.
The role of the light guide plate is to make the light from the LED beads less harsh, making the side panel glow more naturally and elegantly. I tried printing the light guide plate with ABS, and when it lights up, you can see the printing lines. If you don’t mind this, then any white material will do. If you don’t have a multi-color printer, the empty spaces on the original side panel will be filled by the light guide plate.
