Some electronics have gold plated connectors, made of "real gold" to increase conduction and reduce corrosion. However, the plating is very thin.
First off all.... copper is used for many things examples electrical cables,wiring and speakers and the answer is yes it is used for head phone connections
Balls, Headphone,
The different types of audio connections available for electronic devices include analog connections like 3.5mm headphone jacks and RCA cables, as well as digital connections like HDMI, USB, and optical cables.
On many Samsung smartphones, the headphone port is typically located at the bottom edge of the device. However, some of the newer models, particularly the flagship Galaxy S series, have eliminated the headphone jack altogether in favor of USB-C audio or wireless connections. To find the headphone port on a specific model, it's best to consult the user manual or check the device specifications.
Some electrical wiring are made of gold. Its a very thin plating of 24k gold but its better than copper. However the reason gold is best because it is most conductive. Usually gold wire or connecters are only used in data connections for quality. The only two reasons its not common is because gold is to expensive and rare.
Yes, tiny amounts of gold are sometimes used as electrical connections.
gold, that is why they use it for computer connections, also gold does not corrode
You put the headphone in your ears.
ok i need the physical connections made in RFID.
Gold is used in jewellery mainly. Another use is to make connections on a computer circuit.

It prevent corosion and rust if you do.
