Select two design elements that interest you and describe why you think the designer(s) made it that way.
- The position of the handle is mounted on the battery because the battery is heavy. The position of the battery in the handle allows the weight of the megaphone to go down.This is convenient for the user to put in his hand.
- The switch is fixed at the position on both sides of the middle because the user will not accidentally touch the switch when using it.
