PROBLEM TO BE SOLVED: To provide a loudspeaker device which can reduce a height and can attain a high acoustic reproducibility. SOLUTION: A weight 5 as an acoustic load is linked to a driver 4 to substantially increase the inertial mass of a loudspeaker unit 7 and to suppress unnecessary vibration caused by the loudspeaker unit 7 within an enclosure 13, thus increasing an acoustic reproducibility. A diaphragm 3 is held to the enclosure 13, and the enclosure 13 is mounted to a mounting member 6, the mounting member 6 is fixed to a dashboard 2 by a blanket 29 to prevent an air flow within the enclosure 13 from being hindered, a sound pressure waveform generated by the vibration of the diaphragm 3 is accurately reproduced to attain a high acoustic reproducibility, the design flexibility of the shape of the enclosure 13 is increased, the shape of the enclosure 13 is made compact, thus reducing a rising height from the dashboard 2.
