3.5 mm stereo audio jack

FiiO M11 Plus Digital Audio Player Headphone Jack's Product Operating Principle

1. A standard 3.5mm audio plug is inserted, engaging with the internal spring-loaded contacts to establish a secure electro-mechanical connection.

2. The contacts transfer the left, right, and ground audio channels from the PCB to the connected headphones or external audio device.

3. Internal switching contacts can detect plug insertion, allowing a circuit to automatically redirect audio from a device's internal speakers.
