摘要
The present invention relates to a round window driving transducer for easy implantation and an implantable hearing device having the same. The round window driving transducer is implantable in the round window of the cochlea in the middle ear cavity, and has excellent high frequency characteristics, which can assist patients with sensorineural hearing loss to hear sound better. The round window driving transducer can be placed inside the middle ear cavity, radiate sound with high efficiency, and be implanted by surgery using a fixing part formed with shape memory alloy, shape memory resin, or a bendable spring structure. Further, the round window driving transducer can overcome problems of the prior art, such as a difficult surgery and low vibration efficiency, which would inevitably occur when floating mass transducers are implanted in a drilled groove in the bone or when various types of piezoelectric transducers are implanted in the round window.
