Morphology
geophone = geo + phone
The word is built from classical combining forms meaning 'earth' and 'sound', but the specific instrument sense is somewhat specialized rather than fully obvious to an average learner.
Etymology
The word geophone comes from two Greek parts: geo- meaning 'earth' and -phone meaning 'sound', the same -phone you see in telephone. So, a geophone is like an 'earth-sound' device that detects and records the ground's vibrations.
