用于可植入换能器中的振动激励的线传输
摘要：
描述了用于听力植入物的换能器装置(300)。可弯曲振动传输管(302)具有附接到振动激励器(301)的近端，以及具有用于将振动耦合到耳蜗表面的驱动表面(303)的远端。将具有球形外表面的多个振动耦合件(306)以线性序列布置在传输管内。最近端耦合件(304)与振动激励器(301)机械接合。最远端耦合件(305)与驱动表面(303)机械接合。相邻耦合件的外表面彼此机械接合。当振动激励器(301)固定在中耳中时，传输管(302)容纳弯曲，使得驱动表面(303)抵靠耳蜗表面接合，由此经由耦合件(306)和驱动表面(303)将振动激励器(301)的振动耦合到耳蜗表面。
摘要（英）：

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.
