朋友从日本购买了一个耳环型计时器,体积很小的计时器,看起来不起眼,却用得很开心。计时器上有个液晶显示屏,从5分钟开始计时,使用者可以设定需要的时间,例如将数字调到20分,那么20分钟后计时器就会在耳边发出音乐。它也可以设定为1小时或2小时等,即使是长时间也没问题,只要时间一到,就会在你耳边响起音乐。 The friend purchased an earring-type timer from Japan, a very small timer that looked very inconspicuous but used it very happily. There is a liquid crystal display on the timer, starting from 5 minutes, the user can set the required time, for example, the number is adjusted to 20 minutes, then the timer will be in his ear to send music after 20 minutes. It can also be set to 1 hour or 2 hours. Even if it is a long time, there is no problem. As soon as the time is up, it will ring in your ear.
