3.5 mm audio jack

Sony Walkman NW-A306 Headphone Jack's Product Operating Principle

1. When a 3.5mm plug is inserted, its conductive rings make positive contact with the jack's internal spring terminals.

2. This establishes a secure electrical path, allowing audio signals to flow from the PCB to headphones or an external device.

3. An internal switch detects plug insertion, enabling functions like auto-muting of a device's internal speakers.
