This project is a 3D-printed chassis for an Airplay loudspeaker using a Raspberry PI and a HIFIBerry. The 3D-printed Raspberry PI & HIFIBerry holder, was found on Thingiverse:
The project was done as part of the course (41030 Design of Mechatronics) at the Technical University of Denmark - DTU.
The projects was about designing by prototyping, so thats why we both have laser cut parts and 3D printed parts.
We were asked to design a 3D printed loudspeaker that adds value to the consumer via digital fabrication, where we have chosen to focus on designing a speaker for an Office Desktop.
Besides the 3D-printed and laser cut parts, we have used the following components:
Raspberry PI & Power supply.
Tweeter - Datasheet in documents
Sub - Datasheet in documents
During the projects we kept a design/prototype log. If you want to read more about this project, and how our design process was, feel free to visit our blog: https://mechatronicsgroup8.wordpress.com/
If you want to print the loudspeaker chassis yourself, see Post-Printing for needed materials and link to assembly guide.
Tools needed to create the Thing:
Sandpaper (grain 60 & 120)
3D printed Rasberry Pi/HIFIBerry Assembly: https://www.thingiverse.com/thing:1011094
The parts should be printed in 4 separate prints.
The middle chassis is uploaded both with and without the pattern.
Assembly Time: 1 hour
You will need:
- The Raspberry Pi/HIFIBerry enclosure
- 4xM4 screws
To protect the electrical components in the speaker, the Raspberry Pi and HIFIBerry is mounted in a separate closure. The enclosure consists of three components which each need to be 3D-printed. Once you have got the components they are stacked on top of each other and screwed together with 4xM4 screws. (remember to guide the wires through the holes)
You will need:
The bottom, middle & top solid + front grid
2xRound sticks, for the feet
8xM4 nuts and bolts
1xWoofer (Peerless PLS-P830986) - see datasheet in documents
1xTweeter (Peerless BC25SC06-04) - see datasheet in documents
Approx. 600 mm of speaker cable
The assembly consists of four major components. A top, middle and bottom solid plus a front cover. See picture.
You can see an assembly guide here:
The guide will take you through step by step, constructing and assembling the loudspeaker from B&O Create.
