Abstract

The present disclosure has the effect of increasing the utilization of users by dramatically increasing the economy and convenience of users compared to the existing disclosure by simply utilizing a wireless earphone case without any additional devices other than a smartphone and a wireless earphone, and a smartphone user can obtain anti-loss function for smartphone without the inconvenience of purchasing or carrying a separate device other than a smartphone and a wireless earphone.
