'Vibration' isn't captured by the outer ear. It is a sound that is captured through 'bone conduction'. Many hard of hearing or 'deaf' people pick up vibration through their skeletal structure. The Inner ear (the cochlear) is primarilarly bone, where the hair cells live which, by an electrical conversion process, tells the brain, that it has 'heard' a sound. In 'normal' or 'average hearing people', sound is captured by the outer ear in the 'concha',(the shell like part of the ear) and fed into the ear canal towards the eardrum and then into the inner ear. Blockages such as wax can inhibit the transmission of sound through the 'normal' hearing process but usually age contributes to hearing loss in the same way that joints, sight etc deteriorate through advanced ageing. This is due to a 'wearing away' of the hair cells of the inner ear.
Ear drum present at the joint of external and middle ear catches the sound waves.
The part of the outer that is visible to us is called pinna.the pinna collects sound waves and directs them to the ear tube
The outer ear known as the Pinna, deflects and directs the sound waves to the Tympanic Membrane (also known as the ear drum)
The ear lobes collect the sound to the ear drum.

In general, the cochlea. More specifically, an impulse is carried into the brain along the auditory nerve when the tectorial membrane and the basilar membrane inside the cochlea are pressed together by the force of sound waves.
It is located on temporal side of the skull and it is where sounds enters the human ear leading to the tympanic membrane. It is sometimes referred to as the extermal auditory canal.
Sound waves are 'collected' by the ear drum. This is a film stretched across the ear canal. Much like it's namesake, it responds to sound waves by vibrating. These vibrations are read as electrical signals by your nerves, and it is transmitted to brain as impulses.
The two are different because Sound waves are longitudinal mechanical waves, but light waves are transverse electromagnetic waves, and sound requires a medium through which to travel, but light doesn't. Basically, Sound waves move sort of differently than Light waves.
As part of the external ear, the auricle or pinna acts like a horn to capture sound waves. They are then diverted or collected into the auditory canal. At the end of the canal is the tympanic membrane (eardrum) which changes the sound into vibrations to be transmitted further into the ear.
External (outer) ear.
the eardrum is made up of 2 parts gathers and funnels sound waves
external auditory meatus
The external auditory meatus is the ear canal that allows sound waves to pass from the external environment to the tympanic membrane (ear drum).
A waveguide is a structure that guides waves, such as electromagnetic waves or sound waves. There are different types of waveguides for each type of wave.

Tympanic Membrane
Auricles (external ears) in bats are movable and designed to capture sound waves.

cochlear duct
It is located on temporal side of the skull and it is where sounds enters the human ear leading to the tympanic membrane. It is sometimes referred to as the extermal auditory canal.
