Abstract
The utility model discloses a miniature sound box provided with a telescopic resonance cavity. The miniature sound box comprises a sound box upper shell, a sound box middle shell, a sound box lower shell, an audio line, an audio plug, a loudspeaker, a circuit board, and a telescopic resonance cavity, wherein the loudspeaker is disposed inside the sound box upper shell, and an annular boss is disposed in an upper part of the sound box upper shell, with an inner diameter of the boss being smaller than that of the loudspeaker and an outer diameter of the boss being bigger than the inner diameter of the loudspeaker. According to the miniature sound box of the utility model, because the annular boss is disposed in the upper part of the sound box upper shell, and the loudspeaker is disposed inside the sound box upper shell, with the inner diameter of the boss being smaller than that of the loudspeaker and the outer diameter of the boss being bigger than the inner diameter of the loudspeaker, connection between the loudspeaker and the sound box upper shell is secure and reliable and the loudspeaker is not easy to move.
