The inverter tube is connected to and extended along the second side wall. The inverter tube includes at least one inverter channel communicated with the accommodating cavity and a second sound outlet hole communicated with the at least one inverter channel. The inverter tube is retractable and stretchable along the second side wall to make the inverter tube be in a blocked state or be in a communicating state. By stretching or compressing the inverter tube, good sound experience is realized.
