Why do bees buzz?

As if we can't leave without asking question like that. But for the sake question and answer, and for the young ones who are full of curiosity, here's what the guys at Sciencefocus have to offer:

Bees and other Neoptera insects don’t flap their wings directly. Instead, the flight muscles pull on the springy thorax wall to make it ‘ping’ in and out.

Bees also have muscles that can contract multiple times from a single nerve impulse. Together these adaptations allow bees to beat their wings at 200-230Hz (cycles per second). To freeze the movement of a bee in flight, you need to set your camera shutter speed at least 1/300sec.

We hear this as a buzzing tone. Bees also buzz when not flying, to shake pollen from a flower onto their body.
