the disturbance in the medium generates waves
turbine
The sudden flashes of light and trembling sound waves are involved in lightning and thunder. These waves are caused because of the Sudden electrical discharges resulting from atmospheric conditions.
Wind causes waves as it disrupts the water's surface. Its constant and repetitive motion is transferred into the water which generates waves.
Electromagnetic radiation.
When some sound is made (talking, song, bell etc.) it generates some waves. These waves are captured by out ear drums and the mind translates them for us.

wind (windswell) and earthquakes
You can use a hydraulic pump pushing a large piston.
it measures and records the elastic ground vibration called seismic waves that are generates by earthquakes and man made explosions

A microphone does not generate waves but Rather generates a stream of electrons. Waves needs a medium to propagate like air & water. A broadcasting station does send waves as electrons signals but the medium is not physical
