hii!!
here's ur diagram...
working:- the outer part of ear is just like a funnel and the sound enter through it. and the canal whose second end is connected to ear drum. the sound make the ear vibrate and send this vibrations to the inner ear which is connected to brain by a nerve cell and thus we get the message.
hope this helps..!

Working of human ear.
The sound waves are collected by the pinna of outer ear. These sound waves pass through the ear canal and falls on the eardrum. Sound waves consists of compressions and rarefactions. When the compression of sound wave strikes the eardrum the pressure on the outside of a drum increases and pushes the eardrum inwards and where the rarefactions of sound wave falls on the eardrum the pressure of the outside of ear drum decreases and it moves outward.
When the sound waves fall on the eardrum the eardrum starts vibrating to and fro rapidly.
Thevibrating ear-drum causes as small bone hummer to vibrate from hummer, vibrations are passed on to the second bone anvil and finally to the third bond stirrup. The vibrating stirrup strikes on the membrane of the oval window and passes its vibrations to the liquid in the cochlea. Due to this the liquid in the cochlea begins to vibrate. The vibrating liquids of cochlea setup electrical impulses in the nerve cells present in it.
These electrical impulses are carried by auditory nerve to the brain. The brain interprets this electrical impulses as sound and we get the sensation of hearing.
