Orator needing hi-fi component (7)
I believe the answer is:
speaker
'orator' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for speaker that I've seen before include "Commons official" , "Michael Martin MP" , "Leader of the majority party in US House of Representatives" , "He asks for order" , "One presiding over House of Commons" .)
