语音能量给手机供电的可行性分析

摘要

测试手机通话和待机的能耗,通话声波能量和说话气流能量,结果表明在现有手机耗能状况下,通话中的能量即使转化效率达100%也远不足以维持手机正常工作。有关说话声能为手机供电的报道不足为信。%By measuring the energy consumption of mobile phone,the acoustic energy and the speaking air flow energy,the result shows that even if the energy conversion efficiency is up to 100%,it＇s still not enough to maintain the phone to work normally.The reports of power supply of the mobile phone by speaking energy are not convincing.
