System Requirements
Product Summary
A retro-inspired tabletop radio for the IoT era with a wood-cabinet aesthetic, modern digital audio features, and rechargeable battery operation.
Industrial Design Requirements
- Overall product width target: 220 mm
- Visual style: wood cabinet look
- Front panel shall include two primary knobs
- Front panel shall include a small center display
- Product should read as a modern reinterpretation of a classic home radio
Core User Experience Requirements
- Device shall support standalone audio playback without requiring a phone after setup
- Device shall provide a digital screen-based interface in place of analog radio-band tuning control
- Device shall support simple front-panel interaction using the two knobs as primary controls
- Device shall be suitable for casual home use, such as bedroom, office, kitchen, or living room placement
Connectivity Requirements
- Device shall support WiFi connectivity
- Device shall support Bluetooth audio
- Device shall be streaming-ready for internet audio use cases
- Device shall support operation while connected to external power
Audio Requirements
- Device shall prioritize good quality audio over novelty-only sound output
- Device shall include an internal speaker system suitable for tabletop listening

- Device shall be able to run unplugged for a few hours
- Device shall support powered operation from an external input when available
- Battery charging shall be integrated into the product architecture
- Power architecture shall support coexistence of battery operation and plugged-in use
Electronics Implementation Requirements
- The design effort shall result in a schematic concept suitable for implementation in Flux
- The design effort shall result in a PCB concept/layout direction consistent with the industrial design constraints
- PCB placement shall account for front-panel alignment of knobs and display
- System architecture shall leave room for wireless, audio, UI, and power subsystems
User Interface Requirements
- One knob should be assignable to volume / selection behavior
- One knob should be assignable to navigation / mode / tuning substitute behavior
- The display shall present digital navigation and playback information
- UI should be understandable without requiring a touchscreen
Mechanical / Packaging Requirements
- Front-panel component locations shall align with the wood-look enclosure concept
- Internal architecture shall allow space for speaker volume, battery, PCB, and display stack-up
- The front panel should remain visually balanced around the center display and two knobs
Open Items
