Hearing-Assist Earbuds Solution: Dual-Mode PCBA Design with AI Noise Cancellation and Bluetooth Music

Published: 2026-09-11  |  Author: Liwei Electronics

Architecture: One SoC, Three Audio Modes

The whole PCBA is built around a single audio SoC, with only a microphone array, charging management, and a power amplifier around it. Hearing-assist amplification, AI call noise reduction, and Bluetooth music run on one firmware without any external DSP — a smaller BOM and lower power consumption for the whole device.

Application Scenarios: From Home to Meeting Room

Seniors watching TV at home, family members on remote calls, and voice pickup in meeting rooms are all covered by one headset. The hearing-assist mode lifts voices and suppresses ambient noise, while Bluetooth music mode automatically switches to a low-latency link so video and audio stay in sync.

Technical Reliability: Proven in Mass Production

The solution integrates feedback whistling suppression and multi-channel wide dynamic range compression, avoiding the "too quiet" / "too loud" complaint loop. The microphone array and mechanics pass temperature, drop, and aging tests; the finished earbuds support IPX4 splash resistance, delivering consistent quality and a low return rate in mass production.

FAQ

Q: How do hearing-assist earbuds differ from traditional hearing aids?

A: They come in a consumer-electronics form factor that looks and fits like ordinary earbuds, combining music and calls for people with mild hearing loss; traditional hearing aids require professional fitting and cost more.

Q: Does AI noise cancellation drain the battery?

A: No. The inference runs on the SoC audio DSP and activates per scenario — on during calls, idle during music playback — so battery life stays comparable to ordinary TWS earbuds.

Q: Can the solution be customized for our brand?

A: Yes. App-based tuning, scenario modes, and appearance customization are supported. Liwei Electronics delivers everything from chip selection to mass-production testing.

Key Technical Takeaways

  • Single-SoC tri-mode fusion: hearing assist, AI noise-cancelled calls, and Bluetooth music on one PCBA
  • Multi-channel wide dynamic range compression plus feedback suppression for stable listening
  • Mass-production proven with IPX4 splash resistance and consistent reliability
