| 摘 要： | 应用周边固支式圆形压电振子作为驱动元件,将音讯信号转换为振动信号,再利用骨传导方式使人感知音讯信号,在此基础上构建了圆形双晶片压电式骨传导听觉装置。对圆形压电振子进行了建模,利用有限元仿真分析,提出了压电振子支撑方式的优化方案。对设计的压电式骨传导听觉装置进行了实验测试,得到了骨传导装置结构参数对其性能影响的关系曲线。实验研究表明:压电式骨传导听觉装置的基本性能指标能够满足骨传导听觉装置的要求。

| Abstract: | A piezoelectric bone conduction auditory device with the Surrounding-fixed circular piezoelectric vibrator as the drive element to transfer the vibration signal to the sound signal and make it be sensed by the people through bone conduction is present. Optimization scheme of the piezoelectric vibrator supporting way is put forth based on the modeling of the circular piezoelectric vibrator and its simulation analysis by the ANSYS software. A prototype of this kind of the piezoelectric bone conduction auditor... |
