Detailed explanation-1: -Speakers and headphone are output devices. Speakers and headphones are responsible for producing sounds such as music and speech. Speakers and headphones convert digital signals output by the computer into analogue sound waves. Digital signals cannot be heard but analogue wave signals are audible to the human ear.
Detailed explanation-2: -A speaker is an output device that produces sound through an oscillating transducer called a driver. The equivalent input device is a microphone. Speakers are plugged into a computer’s sound card via a myriad of interfaces, such as a phone connector for analog audio, or SPDIF for digital audio.
Detailed explanation-3: -Are headphones input or output devices? When headphones are connected to a computer (laptop, smartphone, etc.), they receive information outputted from the computer. This means headphones are output devices.
