Abstract: A vibrator including a housing, a transducer mounted in the housing such that there is a gap between the housing and transducer; and an impulse force damper that substantially fills the gap. Such a damper includes: a first layer in contact with the housing; and a second layer in contact with the transducer and the first layer; wherein substantially no adhesion is exhibited between the first and second layers or between at least one of the first and second layers and at least one of the housing and the transducer.

Abstract: Presented herein are low-power active bone conduction devices that comprise an actuator that is subcutaneously implanted within a recipient so as to deliver mechanical output forces to hard tissue of the recipient. The low-power active bone conduction devices include an energy recovery circuit configured to extract non-used energy from the actuator and to store the non-used energy for subsequent use by the actuator. The low-power active bone conduction devices may also include a multi-bit sigma-delta converter that operates in accordance with a scaled sigma-delta quantization threshold value to convert received signals representative of sound into actuator drive signals.

Abstract: A bone conduction device includes split high-frequency and low-frequency actuators. The frequency response of the low-frequency actuator can be restricted to the lower range of hearing frequencies to improve performance. The high-frequency actuator can be implanted under tissue close to the cochlea to improve transmission efficiency, since high-frequency vibrations suffer greater attenuation.

Abstract: A bone conduction device comprising a multilayer piezoelectric element. The multilayer piezoelectric element comprises two stacked piezoelectric layers, and a flexible passive layer disposed between the piezoelectric layers. The device also comprises a mass component attached to the multilayer piezoelectric element; and a coupling attached to the multilayer piezoelectric element configured to transfer mechanical forces generated by the multilayer piezoelectric element and the mass component to a recipient's skull.
