Abstract

A portable speaker is always made small and thin in order to carry with easily; however, the volume of the box of the speaker is too small to resonate medium frequency and low frequency sound created by speaker entity. For the consideration of both convenience and high quality sound, a portable and expandable box structure and its device is disclosed. The portable and expandable box structure comprises an expandable box, and the device is easy to carry with when the expandable box is shrunk. When the expandable box is stretched, the volume of the box of the speaker is large enough to resonate medium frequency and low frequency sound, thus the device can get better quality sound. Besides, the device comprises a rechargeable battery, and the rechargeable battery is charged by an external power supply when the external power supply is applied to the device.
