Ever wondered how are wires connected to a connector. How different number of wires are connected to segments of the connector? A connector aka jack for the earphone, headphone, microphone, like any other gadgets has an equally interesting chapter in the book s of engineering. It is among the cheapest part but not the technically inferior. It deserves its attention from the engineers for its design and quality.The connector plays an important part of tranferring signals from the device like mobile, laptops, music players etc to the earphone and the microphone and vice versa. Even a small problem may lead to an unplesant experience with the device. The connector has three contacts/segments/parts called the TIP, RING, and the Sleeve. Therefore it is also called the TRS connector.
