ABSTRACT:
A speaker structure contains a removable food container as a resonant box. The speaker structure contains a baffling device. The baffling device contains a baffle and means for retaining an open top of the food container that is attached to the baffle. When the food container is incorporated with the baffling device, the food container works as a conventional resonant box. Furthermore, a user can freely remove the food container from the baffling device and the removed food container may serve its original food-containing function.
