PURPOSE: To obtain a speaker device which can considerably improve the reproduction of low frequency sound, by forming a speaker cabinet having a large compliance.

CONSTITUTION: In sealing a solution representing a negative shift in accordance with the Raoult's low in an enclosed cabinet to realize the coexistence of gas and liquid two phases and in keeping the pressure in the cabinet to 1atm., the pressure change caused by a diaphragm is absorbed with the phase change between the gas and liquid and the cabinet having a considerably high compliance is made. Thus, a speaker device which improves the reproduction of low frequency sound considerably is obtained.
