Kuulokeliitäntään

Kuulokeliitäntään refers to the audio jack or port on an electronic device that allows users to connect headphones or other audio output devices. This connection is typically a 3.5mm (1/8-inch) TRS (Tip-Ring-Sleeve) connector, which is the most common standard for consumer audio. The TRS connector has three distinct conductive sections: the tip, the ring, and the sleeve. The tip usually carries the left audio channel, the ring carries the right audio channel, and the sleeve serves as the ground connection.

In some devices, particularly smartphones and tablets, the 3.5mm headphone jack has been replaced or supplemented by other connectivity options. USB-C ports are increasingly being used to carry analog audio signals, either through an adapter or directly if the device supports it. Bluetooth technology has also become a popular wireless alternative, allowing headphones to connect without any physical cable. While these alternatives offer convenience and new functionalities, the 3.5mm jack remains prevalent in many audio devices like laptops, desktop computers, televisions, and older audio equipment. The specific implementation of the kuulokeliitäntään can vary, with some ports supporting only stereo audio, while others may also incorporate microphone input for headsets.
