Juhtmekõrva

Juhtmekõrva, also known as a headphone jack or audio jack, is a standard interface used to connect audio devices to other devices, such as smartphones, tablets, and computers. It is typically a small, circular port found on the side or top of these devices. The jack is designed to accept a plug, usually a 3.5mm or 2.5mm TRS (Tip-Ring-Sleeve) plug, which carries audio signals.

The headphone jack has three main components: the tip, the ring, and the sleeve. The tip carries the audio signal for the right channel, the ring carries the audio signal for the left channel, and the sleeve is typically used for grounding or carrying a second audio channel, such as a microphone signal.

The headphone jack has been a ubiquitous feature on consumer electronics for decades, but its popularity has declined in recent years due to the rise of wireless audio technologies and the adoption of USB-C as a standard connector. Despite this, the headphone jack remains an important interface for many users, particularly those who need a reliable, wired connection for audio playback or communication.

In summary, the headphone jack is a versatile and widely used interface for connecting audio devices to other devices. Its design and functionality have remained largely unchanged since its introduction, making it a familiar and reliable feature on many consumer electronics.
