日本生产了一种声控照明时钟,钟内装有音频传感器,只要人发出“唏——”“咻——”一类的摩擦音一秒钟,钟面照明灯即会自动点亮八秒。晚上,在黑暗的房间内,可借助钟面照明灯看清时间。在突然停电时,先靠声控点亮照明灯后,再将开关置于“常明”位置,还可供室内照明数小时。 Japan produces a voice-activated lighting clock with an audio sensor in the bell. The clock light illuminates automatically for eight seconds as long as the person emits a “唏-” “咻-” type of fricative for one second. Night, in the dark room, you can see the time with the clock face light. In a sudden power outage, the first light by voice lit lights, and then the switch is placed “Chang Ming” position, but also for indoor lighting for hours.
