If you tap the microphone, the sound of the tap goes through the amplifier, comes out the speaker and re-enters the mic. This feedback loop happens so quickly that it creates its own frequency, and that produces the howling sound — an oscillation triggered by sound entering the microphone.

“In a well-designed system, the irritating high-pitched brand of feedback isn’t much of a problem unless someone points a mic into a monitor.
