摘要:
为了使压电骨传导助听器对声音信号的传递更准确、更高效,提出一种具备对高低频声信号进行分频传导能力的新型压电骨传导助听器。该助听器利用方形和矩形2个压电振子独立驱动,可以将高低频声音信号分频后通过骨传导方式传至内耳。对助听器的主要部件压电振子设计参数进行了仿真分析,依据仿真分析的结果,制作了压电骨传导助听器试验样机,搭建了测试系统,对助听器样机进行了试验测试。测试结果表明,矩形和方形振子的阶跃响应速度相差约4 ms;中低频段频率响应中矩形振子的声压值突变平均超过方形振子约10 dB,中高频段频率响应中方形振子的声压值突变平均超过矩形振子约13 dB。试验结果证明该助听器可以实现声音信号的分频传导。
