3.5 mm earphone jack

Sangean DT-250 AM/FM pocket radio Headphone Jack's Product Operating Principle

1. When an audio plug is inserted, internal spring-loaded contacts securely engage with the plug's tip, ring, and sleeve for a stable connection.

2. Audio signals travel from the device's PCB, through the jack's low-resistance contacts, and are transmitted to the connected headphones or speakers.

3. An internal switching mechanism detects the plug's presence, often used to reroute audio, such as disabling a device's internal speakers.
