Abstract

A ribbon transducer has its ribbon (10) which is held at each end made capable of lateral movement for adjustment purposes by providing a plurality of traverse cross-suspension elements (12) to which the ribbon is secured, with each of these cross-suspension elements being capable of transverse displacement, for example by rotation of mounting pillars (14a, 14b).
