A piezoelectric drive ( 1 ) with an inner part ( 2 ) that is surrounded by an outer part ( 3 ). The inner part ( 2 ) includes at least one piezoelement ( 9 ) that is actively connected to an oscillation element ( 5 ). The oscillation element ( 5 ) has a middle part ( 6 ) about which at least one arm ( 7, 15 ) is arranged. The arm is actively connected to the outer part ( 3 ) via an interaction region ( 16 ) and is designed such that, when set into oscillation by way of the at least one piezoelement ( 9 ), it drives the outer part ( 3 ) relative to the inner part ( 2 ).
