<p>A micro louderspeaker box with a telescopic resonance cavity (2) is provided, and comprises a trumpet, an upper shell of the louderspeaker box, a middle shell of the louderspeaker box, a lower shell of the louderspeaker box, an audio cable, an audio plug, a circuit board, a transition joint (1), and the telescopic resonance cavity (2). The telescopic resonance cavity (2) is connected with the transition joint (1). Then the transition joint (1) is connected with the upper shell of the louderspeaker box. The telescopic resonance cavity (2) is fixed with the transition joint (1) through buckling. In the technical solution, the transition joint (1) is provided with a large buckle (3), and the large buckle (3) and the telescopic cavity (2) are in fixed connection, so that the telescopic resonance cavity (2) is not deformed, and the installation is relatively rapid and convenient.</p> |
