Abstract:
1. A bone conduction device comprising: a vibrator configured to vibrate in response to sound signals received by the device; a housing mass comprising a housing for one or more operational components of the device integrated with a vibrator mass, wherein the housing mass is attached to the vibrator so as to move along with the vibrator in response to the vibration to generate an output mechanical force representative of the sound signals; a coupling configured to attach the device to a recipient so as to deliver the mechanical forces generated by the movement of the housing mass to the recipient's skull; one or more stops positioned on the coupling; and one or more over-load protection elements disposed between the one or more stops and the vibrator and configured to contact the one or more stops to prevent undesired movement of the vibrator and housing mass in the direction of the coupling.
