hörlursutgången

Hörlursutgången, often translated as headphone jack or audio output, refers to the physical connector on an electronic device designed for plugging in headphones or external speakers. This interface allows users to listen to audio privately or amplify it for a larger audience. The most common type of hörlursutgång has historically been the 3.5mm TRS connector, also known as a mini-jack. This connector typically carries stereo audio signals, with separate channels for the left and right ears.

Over time, variations and alternative connector types have emerged. Some devices may feature a 6.35mm (quarter-inch) jack, often found in professional audio equipment like amplifiers and musical instruments, due to its larger size and more robust connection. More recently, digital audio transmission through USB-C or Lightning connectors has become increasingly prevalent, particularly in smartphones and tablets. These digital outputs often require an adapter or headphones with an integrated digital-to-analog converter (DAC) to function with traditional analog headphones. The presence and type of hörlursutgång can significantly influence a device's audio capabilities and the user's ability to connect external sound peripherals.
