Every time I get up in the morning and go to the bathroom to wash, I can listen to the first music in the morning. I turn up the handle of the faucet and the water flows out like music. After washing, I turn back the handle of the faucet and the music stops. This is a Bluetooth speaker, which uses people's common understanding of the faucet switch properties to let users experience a new opening method, the two events of turning on the faucet and playing music are related, and the faucet handle is grafted to the speaker switch. When people see this speaker, the flat faucet handle shape can make the user directly perceive its opening mode and use it naturally. In addition, the volume can be adjusted by dialing left and right, reducing the volume to the left and increasing the volume to the right, through the whole process of getting up and washing in the morning, can you think of any interesting events for a certain link? Might as well share it with us.
