传统助听器的功能是采集、放大声音并将放大的声音通过耳模或直接通过助听器传导至外耳道。而振动声桥属于植入式助听装置,通过电磁感应原理将声能转换成直接驱动听骨链的机械振动,从而放大听骨链的自然振动来提高听力。传统助听器存在多种局限性,如堵耳效应、啸叫、言语声失真 The function of a traditional hearing aid is to collect, amplify and amplify the sound through the ear mold or directly through the hearing aid to the external auditory meatus. The vibration acoustic bridge is an implantable hearing aid, and converts the acoustic energy into the mechanical vibration that directly drives the ossicular chain through the principle of electromagnetic induction, so as to amplify the natural vibration of the ossicular chain to improve hearing. There are many limitations of the traditional hearing aids, such as blocking the ear effect, howling, speech distortion
