Ear canal
The pinna of the ear collects sound waves. This is the part you see on the side of the head.
The tympanic membrane, also known as the eardrum, is the part of the ear that converts sound waves into vibrations. When sound waves reach the eardrum, it vibrates and transmits these vibrations to the middle ear.
The auricle or pinna of the outer ear acts like a horn to capture the sound waves which are then tunneled into the auditory canal and strike the tympanic membrane (eardrum).
gathers sound waves.
That part is called as ear lobe or the pinna of the ear.
Cochlea is the part of inner ear, which detects sound waves.
The eardrum

No part of the ear actually amplifies sound, but the middle ear changes the nature of the waves from high amplitude to low amplitude but stronger waves to make the transition from air to liquid.
Sound waves enter the ear through the outer ear, specifically through the ear canal. This canal funnels the sound waves towards the eardrum, which is located at the end of the canal in the middle ear.
