What is the difference between buzzer and speaker?
A buzzer is usually a self-oscillating device that moves a diaphragm repetitively and can really only produce a single sound. A speaker has a moving coil connected to a diaphragm and a magnet inside the coil. Then any signal applied to the coil moves the diaphragm at the frequency of the signal.
Is a buzzer input or output?
The buzzer is mainly used as an output device in an electronic circuit. An output in an electronic system is where power or information leaves the system. In the case of the buzzer, power is leaving it through means of audible sound and is the main reason a buzzer is an output device.
