A (final) stab at the etymology of Seraphone?

Those with a classical background will know that the word 'phone' comes
from the Ancient Greek for 'voice' or 'sound', and 'sera' is the plural
of 'serum' in Latin, meaning 'to do with the blood'.

I would therefore hazard a guess at 'Seraphone' really meaning 'bloody
noise'.  Could this be a plausible explanation??!
