* Plug: This is the part that you insert into the jack. It typically has pins or contacts that make the electrical connection.
* Jack: This is the socket or receptacle on the device that the plug fits into. It has holes or slots that accept the plug's pins.
Some connectors may have additional features like:
* Shell: This is the outer casing of the connector that provides mechanical support and insulation.
* Strain relief: This helps to prevent damage to the connector by reducing stress on the cable.
* Grounding: This ensures a safe electrical connection and prevents interference.
However, the plug and jack are the fundamental components that enable the audio signal to flow.
