'vibration-amplifying' is a modern English compound formed from 'vibration' + 'amplifying'. 'vibration' originates from Latin 'vibratio' (from 'vibrare') where the root 'vibrare' meant 'to shake'. 'amplifying' derives from Latin 'amplificare', where the element 'ampli-' meant 'large' and 'ficare' (from 'facere') meant 'to make'.

'vibration' came into English via Latin 'vibratio' (and related medieval forms) to Middle English and then modern English as 'vibration'. 'amplificare' passed into Old French/Anglo-Norman and Middle English as forms that eventually became the modern English verb 'amplify' and its present participle 'amplifying', which together produced the compound 'vibration-amplifying'.

Initially 'vibration' referred broadly to shaking or oscillation and 'amplify' meant to make larger; over time these combined to denote specifically the increase of the amplitude or intensity of vibrations (i.e., making vibrations stronger).
