3.5 mm audio

Korg Volca Keys Analog Loop Synthesizer Headphone Jack's Product Operating Principle

1. When a 3.5mm plug is inserted, its contacts (Tip-Ring-Sleeve) align and securely connect with the internal phosphor bronze terminals of the jack.

2. The connection completes the circuit, allowing low-resistance transmission of audio signals from the source device to the connected PCB.

3. Upon withdrawal of the plug, the internal contacts disengage, instantly breaking the audio signal path with high insulation resistance.
