Summary: | In accordance with one aspect of the disclosure, a method of operating an acoustic system including detecting an ultrasonic sound signal and pattern matching the received ultrasonic sound signal to determine when the received ultrasonic sound signal is a desired ultrasonic sound signal. The method includes sending a signal to at least one electronic component when the received ultrasonic sound signal is the desired ultrasonic sound signal. The method includes operating the microphone in a lower power state when the received ultrasonic sound signal is not the desired ultrasonic sound signal.
根据本公开的个方面,种操作声学系统的方法包括:检测超声波信号,并且对接收到的超声波信号进行模式匹配,以确定接收到的超声波信号何时是希望的超声波信号。该方法包括:在接收到的超声波信号是希望的超声波信号时,向至少个电子组件发送信号。该方法包括:在接收到的超声波信号不是希望的超声波信号时,按低功率状态来操作所述麦克风。 |
