■ In making
I bought a clock-type device and used the weather forecast and transfer information conveniently.
However, when I tried it in the city, I sometimes heard it at a low volume, or suddenly made a loud noise in public facilities, which caused inconvenience.
If you use a smartphone, you can use the volume key to deal with the humor, but many wearable devices do not have a volume key.
I created it because I wanted a volume control function that I could use with the same feeling.
