Since the hanging part is a hollow structure, it can accommodate at least one PCB board, at least one battery and at least one reflection tube inside. Since the speaker unit of the speaker accommodating part is connected to the PCB board through at least one signal line, when the speaker unit makes a sound, its sound will bounce back and forth in the internal space of the hanging part, and the sound waves generated by the rebound will be transmitted through the reflection tube as the opposite sound waves.
