Morphology

diaphone = phone (semi-transparent) = dia + phone

The element 'phone' clearly signals sound or a sound-producing device, but 'dia-' is a less familiar combining form to many learners so the exact sense ('through sound' or specific technical meaning) is not fully predictable.

Etymology

Diaphone comes from Greek parts dia- 'through' and -phone 'sound', the same -phone you find in telephone. So a diaphone is like a 'sound that carries through', a very loud foghorn whose strong two-tone blast travels far to warn ships.
