Breaking away from the traditional image, all buttons at the front have been changed to touch-pad buttons, creating a clean & stylish image. In order to make this simple shape more attractive to users, the device has been designed to make the product look like it is sinking in water. The speaker is completely differentiated from other products on the market. It is a speaker unit (parabola speaker unit) created using a shiny pressing manufacturing method. Frequently used buttons are grouped into icons and rarely used buttons are located inside the door to minimize clutter. Instead of the traditional chrome coating, an aluminum coating is used to reduce damage to the environment. The hot and cool molding method has been used to make ABS, and is set firmly with the least number of pieces. The touch-sensitive interface with lighting effect has been used. The volume sensor has a circular design to emphasize the fun factor.
