The "electronic" of the keyboard which is hit by the keys touching it.
The drum head is usually the part of the drum that vibrates when hit. The drum head along with the material and size of the drum determines the sound that it makes.

I dont think how far my answer is correct but, the amplitude of the sound produced at the centre of the drum is more when compared to its edges. this might be due to the tension in the leather surface of the drum and the law of vibrations.ie, towards the centre where at a particular point when moving away from the edges of the drum vibrates more than at edges. Here, the force of the stick( if a stick is used) with which the sound is produced must also be taken into consideration and also the make of the material with which the sound is being produced.
Vibrating 'air' particles, through a transfer of energy; creating a sound wave which then reaches your ears and vibrates your ear drum. (doesn't have to be air, sound also travels through water ect)
Resonance can occur when an object vibrates at another objects resonant frequency.
Transverse Wave
The telephone and your ears. Sound is basically the vibrations of air. Bang a drum, drum vibrates, vibrations cause air to vibrate, vibrations travel in air, reaches ear drum, ear drum vibrates, brain interprets vibration as banging drum.
The head of the drum, the part that is struck by drum sticks, vibrates.
The skin vibrates when you hit them.
The skin of the drum vibrates to produce sound.
The bottom.skin kf a snare drum.:)
Ear drum

The ear drum
The air inside the drum.
The head of the drum vibrates when struck. However, the whole drum reverberateswith that vibration. This is what gives the drum its tonal quality.
The tightly stretched surface (membrane) of a drum vibrates.
The head of the drum vibrates. If you get some dry rice grains and put them on the drum head, they will move around.
They both have stretched membrane or a drumhead which is hit and the one that vibrates to produce that sound of the drum.
