Abstract
A waterproof protection cover and an acoustic component are each disposed inside a portable device provided with a chassis having one or more holes. The acoustic component emits sound. For the acoustic component, an acoustic component having a maximum acoustic output between 0.25 W or more and 0.8 W or less is used. The waterproof protection cover secures an area of 114 mmor more as an acoustically transparent portion for transmitting acoustic energy from the acoustic component.
