<p>Disclosed is a miniature sound box with a telescopic resonance cavity (4). The miniature sound box with the telescopic resonance cavity (4) comprises an audio line, an audio plug, a sound box upper case (6), a sound box middle case, a sound box lower case, a loudspeaker, a circuit board, and the telescopic resonance cavity (4). The miniature sound box with the telescopic resonance cavity (4) further comprises a transition piece (1). The telescopic resonance cavity (4) is connected to the sound box upper case (6) through the transition piece (1). Since the telescopic resonance cavity (4) and the sound box upper case (6) are fixed by using the transition piece (1), making the fixing between the telescopic resonance cavity (4) and the sound box upper case (6) more reliable.</p> |
