A hearing actuator (10) for implantation in the middle ear of a user. The actuator comprises transducer means (for example a piezoelectric device) (12) for converting electrical input signals into mechanical vibrations, and attachment means (16) for attaching one end of the transducer means to a first part of the middle ear. The actuator also comprises contacting means (14) which extends from an opposite end of the transducer means such that a longitudinal axis of the contacting means is substantially parallel to a longitudinal axis of the transducer means. The contacting means is for contacting a second part of the middle ear (to which it may be attached), so as to transmit the mechanical vibrations of the transducer means thereto.
