英文摘要：

In order to help the impaired hearing patients to hear, a novel kind of piezoelectric bone conduction hearing device was proposed based on bone conduction hearing and the inverse piezoelectric effect. It used piezoelectric bimorph driven components that convert audio signals to vibration signals. The prototype headset piezoelectric bone conduction hearing device was designed and manufactured, then simulation analysis was performed. A series of tests including the comparison with electromagnetic bone conduction devices were carried out to evaluate the performance of the device in timbre, noise, output force and sound-force sensitivity. Experimental studies showed that the basic performance of piezoelectric bone conduction hearing device met the requirements of bone conduction hearing device.
