PROBLEM TO BE SOLVED: To provide a speaker device capable of further reducing the size, and having excellent sound reproducibility and installation stability.SOLUTION: A speaker device comprises: a loudspeaker unit 2 that generates sound by converting an electric signal into an oscillation; an enclosure 3 that covers a back side of the loudspeaker unit 2; and a body part 4 that holds the enclosure 3. The enclosure 3 has: an outer case 11 and an inner case 12, each having a bottomed cylindrical shape of which one end is opened; a vacuum double layer structure in which each of opening ends 3a is connected in a state where the inner case 12 is enclosed in an inner side of the outer case 11, and a vacuum layer 13 is arranged between the outer case 11 and the inner case 12. The body part 4 has an upper cover 4a holding a front surface side of the enclosure 3, and is attached to the enclosure 3 in a state where the upper cover 4a does not contact with the speaker unit 2.SELECTED DRAWING: Figure 9 |
