Abstract
The inside of the housing of an acoustic device, such as an earphone, is divided into two or more spaces based on a driver. Diaphragms are disposed to cover a nozzle communicating with an ear of a user and a vent hole formed in the back of the housing. Optimum sound quality can be secured by adjusting the sizes of the spaces formed by the diaphragms and the housing and the locations where the diaphragms are disposed. When the housing is of a sealed type, low-band sound pressure can be effectively prevented from being lost.
