Combating KT148A voice chip burnout in charging pile apps? Pins 7 & 8 (SPK outputs) can fry from surge/EMI. Design tip: Add an LC filter (33uH inductor + 102 cap) on the output and use twisted-pair wiring for the speaker. This simple combo filters noise and reduces common-mode interference, ensuring long-term chip stability in tough environments. #KT148A #HardwareDesign #EmbeddedSystems #EMC #SurgeProtection #EVCharging #ElectronicsEngineering #Reliability

Hey maker community! 👋

Sharing hard-won audio design lessons for KT148A voice chip users:

The volume struggle is REAL when:
• Using <1W film speakers
• Housing design ignores acoustics

But good news! We found:

🔹Paper cone speakers (AliExpress) work wonders
🔹Proper venting > amplifier mods
🔹Size DOES matter for speakers

Anyone else solved this differently? Let's compare notes!
