摘要
为了延长人工耳蜗声音处理器的续航时间,文章设计了一种新型的人工耳蜗声音处理器系统。该系统具备自适应特性,能够根据植入体的不同耦合距离进行匹配,并动态地控制主控芯片和外载模块的运行功耗。该低功耗系统设计关键在于主控芯片的动态功耗管理、设备管理优化以及运行状态切换,能够显著减少在不同耦合距离和声音环境下无线电发射功率以及设备运行时的功耗损失。
In order to enhance the battery service time of cochlear implant sound processor,a novel cochlear implant sound processor system has been designed.This system exhibits self-adaptive characteristics,enabling it to adapt to varying coupling distances of the implant,and dynamically regulate the operational power consumption of the main control chip and external modules.The key of this low-power system lies in the dynamic power management of the main control chip,the optimisation of the device management,and switching of the operation states,which significantly reduces radio transmitter power over varying coupling distances and acoustic environments and power loss during equipment operation.
