A transducer arrangement (300) for a hearing implant is described. A bendable vibration transmission tube (302) has a proximal end attached to a vibrational actuator (301), and a distal end with a drive surface (303) for coupling vibration to a cochlea surface. Multiple vibration coupling pieces (306) with spherical outer surfaces are arranged in a linear sequence within the transmission tube. A proximal-most coupling piece (304) is mechanically engaged with the vibrational actuator (301). A distal-most coupling piece (305) is mechanically engaged with the drive surface (303). Outer surfaces of adjacent coupling pieces are mechanically engaged with each other. When the vibrational actuator (301) is affixed in the middle ear, the transmission tube (302) accomodates bending so as to engage the drive surface (303) against the cochlea surface, thereby coupling vibration of the vibrational actuator (301) via the coupling pieces (306) and the drive surface (303) to the cochlea surface.
