Mobile Audio jack definition in bangladesh?

A widely used connector for plugging in standard music headphones can be found on various electronic devices such as music players, computers, and most other devices with audio outputs.

This connector supports stereo sound and may also include a microphone, depending on the number of separate rings on the jack.

Some smartphones are equipped with a smaller variant of this connector called a 2.5 mm jack.

Headphones provided with mobile phones often feature a microphone along the cable and a remote button, allowing users to manage calls without directly using the phone.

To save internal space, some manufacturers choose to place a 3.5 mm audio jack on the remote control instead of directly on the phone itself. This design decision enables users to retain the functionality of the remote control and microphone while using third-party headphones.
