A microphone has a voltage output and an acoustical input. Only the sound wave can move the diaphragm of the microphone and a voltage signal comes out. That goes to to an amplifier and to a loudspeaker.
Because the microphone delivers voltage that goes to the amplifier. The microphone is an output device. A loudspeaker is an input device.
A microphone is a source that sends an output to its male plug. A loudspeaker is a load and receives an input at its female plug.
An input, with regards to electronics, is any device or peripheral that provides data to an information processing system, such as a computer. An example of an input device is a keyboard which inputs data to a PC.
An input device is basically any device or peice of equipment that you connect to a computer ect that sends data into the computer to be processed. Examples can include anything from keyboards or mice to temperature and pH probes to digital cameras. Note that devices such as printers and moniters are OUTPUT devices, ie they display information.
A microphone and a computer mouse has only an output. That is an input device. A loudspeaker and a printer has only an input. That is an output device. A read-write CD/DVD, floppy disk, tape drive, and hard drive are all I/O devices because they can be used to store and retrieve data.
