"Smart Audio Device PCB Design Bluetooth Speaker, Amplifier, and Soundbar"

Turning an audio product idea into working hardware? I design circuit boards for smart, connected audio devices Bluetooth speakers, soundbars, portable amplifiers, and voice-enabled audio gadgets. Every board is built around clean power delivery, low-noise audio paths, and reliable wireless performance, so your device sounds as good as it looks.

What I offer:

• Bluetooth speaker and soundbar PCB
• Portable and desktop amplifier circuit (Class D, Class AB)
• Voice-assistant/smart audio device hardware (mic array, wake-word ready circuits)
• MCU-driven audio control (ESP32, STM32 WiFi/BLE audio streaming and app control)
• Battery-powered audio device design
• Multi-driver/multi-channel speaker circuit
• Volume control, EQ, and input switching circuits
• Fritzing prototyping diagrams for early-stage visualization
• Production-ready schematic capture and PCB layout (Altium, KiCad, or Eagle)
• Component selection and BOM optimization
• Gerber files, DFM checks, and prototype-ready outputs

Send me your product concept, target features, or existing schematics, and let's build audio hardware people actually want to use.
