Abstract: A portable over-the-ear miniature sound box device comprises a loudspeaker, a first chamber and a second chamber. The loudspeaker is located in the first chamber. A first sound output hole of the first chamber is connected with a sound-receiving hole of the second chamber. A second sound output hole is disposed at the opposite side of the sound-receiving hole of the second chamber. A sound signal first resonates in the loudspeaker and is then sent through the first chamber to second chamber. Sound resonates again in the second chamber and is finally sent out via the second sound output hole. Because the sound signal resonates twice and is more convergent and the first resonance occurs in the loudspeaker, the bass will be thicker and more easily heard by human ears, hence solving the problem of easy divergence of the bass.
