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.

Claim (Index 3):
An earphone having multiple diaphragms, the earphone comprising:\n a housing configured to form an appearance of the earphone while surrounding the earphone; a driver disposed inside the housing, and including a main diaphragm; and an additional diaphragm disposed at a boundary of a space formed by the housing or adjacent to the boundary; wherein the space formed by the housing includes a first space formed on one side and a second space formed at a side opposite to the one side based on the driver, and the additional diaphragm includes a first diaphragm disposed at a boundary of the first space or adjacent to the boundary and a second diaphragm disposed at a boundary of the second space or adjacent to the boundary.
