Building a Low Power DiY marine bluetooth speaker set

Click For Summary
SUMMARY

The discussion focuses on building a low-power DIY marine Bluetooth speaker set, specifically a 1x12 speaker designed to fit within boat compartments. The proposed setup includes a PSoC (Cypress Programmable System-on-Chip) for Bluetooth connectivity, while the power source remains a critical concern, with considerations against using a car battery due to size and an RC battery due to insufficient power. Participants emphasize the importance of balancing size, power requirements, and battery life for optimal performance.

PREREQUISITES
  • Understanding of PSoC (Cypress Programmable System-on-Chip) for Bluetooth integration
  • Knowledge of speaker design principles, particularly for 1x12 configurations
  • Familiarity with battery types and their specifications, including car and RC batteries
  • Basic skills in DIY electronics and audio equipment assembly
NEXT STEPS
  • Research efficient power solutions for portable audio systems
  • Explore Bluetooth audio modules compatible with PSoC
  • Investigate lightweight battery options that provide sufficient wattage for audio applications
  • Learn about acoustic design principles to optimize sound quality in compact speaker enclosures
USEFUL FOR

DIY enthusiasts, marine audio system builders, and anyone interested in creating custom Bluetooth speakers for boats.

My dad has been asking about some speakers for his boat, something that will move a bit of air, not too big though. I'm thinking 1x12. He also wants it bluetooth and powered externally, so it doesn't drain the boat battery.

So I'm thinking 1x12 speaker in a small box that can fit inside the compartments in the boat, psoc hookup for bluetooth, and then the real question is power. Spacially I think a car battery is just too big, powerwise I think something like an RC battery is too small.

Thinking of this as a DIY project, what suggestions/advice/improvements do you guys have?

Why DIY instead of an existing commercial solution? What kind of wattage and battery life are you looking for? I'm seeing 12" bluetooth speakers on Amazon (with batteries) starting at $90.
