Portable passive sound amplifier with power bank system
View Patent ↗There is provided a hub device having a unitary body with walls located on top, bottom, front, rear, and a pair of side walls defining a cavity within the unitary body which has an internal power source and a set of electronics for wireless and wired power charge capabilities. The front wall has an opening for receiving a base piece into the cavity of the unitary body, with the base piece having a bottom surface and a locking ridge extending from the bottom surface. The unitary body has a U-type or other types of sound tubes extending from an interior top surface of the top wall into the cavity, defining an acoustic pathway and having a front output grill surface to allow the amplified sound waves exit from the unitary body.
