Tabletop FM Radio

thingiverse

This table top radio features a module available at http://www.ebay.com/itm/252493815508. An alternative module can also be used, although it hasn't been thoroughly tested: http://www.ebay.com/itm/131571817336. The speaker recommended is an original Tivoli Audio speaker found at http://www.ebay.com/itm/332125249549, which significantly enhances sound quality and matches the module's specifications. The antenna can be either internal or external, with a panel F-type connector. An internal setup involves wrapping 75 cm of copper unifilar waxed or insulated wire around the bass reflex and attaching it to the power plug in the back, resulting in excellent performance. This method has been tested successfully. A common dc connector, available at http://www.ebay.com/itm/332068139283, serves as the power plug. It should be secured with hot glue for durability. The switch can resemble the one found at http://www.ebay.com/itm/182050318772. Alternatively, a version of the back panel includes a hole for a 6mm dc switch, accommodating users who prefer a switch. There are four spots on the box designed specifically to hold rubber feet, as seen in http://www.ebay.com/itm/112253048709. If printing is chosen, the case must be filled with foam to reduce midrange resonance. This radio draws inspiration from the Tivoli Pal but incorporates the case style of the Tivoli Model One. The design has been printed and awaits assembly once the module arrives. Upon completion and testing, this radio functions well, delivering great sound quality, clarity, and sufficient volume. However, there are a few issues to address: The module is designed for stereo output, yet only one channel (left) was connected initially. For optimal performance, a summing circuit should be used, as described in http://www.rane.com/note109.html. Print Settings: * Printer: Prusa * Printer Model: Prusa Mk2 * Rafts: Not Required * Supports: Not Required * Resolution: 0.20 mm * Infill: Various Densities Notes: - Front and back panels should have a honeycomb infill of at least 30%. - The box's walls can be printed with an infill density of up to 15% or less. - Buttons and the grill should have a higher infill density, such as 40% or more. Post-Printing Issues: * Air tightness is crucial for this bass reflex cabinet. To ensure proper performance, apply silicone glue around the front panel's edges and consider adding a thin line of silicone along the inner perimeter of the box before closing it. * Tolerances between the printed parts may vary depending on your printer. Ensure that all parts fit together smoothly after trimming the first layer. The design accommodates these tolerances. This project was created using Fusion 360, which facilitated precise design and modeling.
