Morphology

pistonphone = piston + phone (semi-transparent) = piston + phone

Formally a compound 'piston' + 'phone' so components are clear, but the technical meaning (a calibration sound-generator) and the combining-form use of 'phone' may not be obvious to general learners.

Etymology

The word pistonphone comes from piston, a part that 'moves back and forth', and phone, which means 'sound' as in telephone or microphone. So a pistonphone is a tool that uses a moving piston to make a very exact sound to check and set microphones.
