Middle-ear implants consist of a microphone, an audioprocessor, a battery, a receiver and a transducer. Transducers can be classified in three groups: piezoelectric, electromagnetic, and electromechanical. The middle ear transducer (MET) system (Otologics) is composed of an outer part that uses a multichannel digital acoustic signal processing system that transforms this acoustic signal into an electromagnetic stimulus. This system has fully implantable devices. The Vibrant Med El Soundbrige uses an electromagnetic design in which a floating mass transducer is crimped around the long process of the incus by a titanium strap, transmitting vibration to the ossicular chain.
中耳植入物由麦克风、音频处理器、电池、接收器和换能器组成。换能器可分为三类：压电式、电磁式和机电式。中耳换能器（MET）系统（Otologics公司）由一个外部部件组成，该外部部件使用多通道数字声学信号处理系统将这种声学信号转换为电磁刺激。该系统具有完全可植入的设备。Vibrant Med El Soundbrige采用电磁设计，其中一个浮动质量换能器通过钛带压接在砧骨长突周围，将振动传递到听骨链。
