Description

CROSS REFERENCE TO RELATED APPLICATIONS This application claims priority to and benefit of U.S. Provisional Application Ser. No. 63/442,992 filed on Feb. 2, 2023 and incorporated by reference herein in its entirety. FIELD OF THE INVENTION The present invention relates generally to a portable passive or electrical sound amplifier with a power bank system and hub capabilities for operation with one or two hands. BACKGROUND There are sound amplifiers, generally electrical, with portable batteries that have been used for years to charge devices. In addition, there are accessories with large structures to mechanically increase the volume of phones, many users use their internal speaker to play music or stream content on their phones without any sound amplification or the ability to have access to powered amplification. Increasing the soundstage of a phone without the use of auxiliary powered or Bluetooth connection is highly desirable for quick connection or non-powered environment available. There is a need for a new solution that provides users with a portable power bank, a device that charges phones, amplifies sound without consuming power, or with electrical speakers, to be used with cellphones and deployed with one or both hands in four positions, and all of this packed into a small case that can be used at home, and personally carried by users in a jacket, or backpack, or purse, etc, when they leave home. SUMMARY OF THE INVENTION The present invention provides the user with a new type of portable passive sound amplifier, with a power bank and a hub with connectivity and capabilities for enhanced performance and entertainment in any place, and especially when traveling. With the present invention, the hub has extended functionality within the apparatus as a unitary system or with attachments. This invention charges phones, tablets, among other apparatuses, wired or wireless, has ports to charge other apparatuses, increase the volume passively without consuming power from the power bank or from the cellphone, and it can be used in different applications such as personal use, to enhance the entertainment or work anywhere. the present invention relates to a hub with multi-functional capabilities for power bank, wireless and wired charging connectivity, a special thin sound tube that utilizes compression technology, that captures and guides the soundwaves through a specialized horn design to increase the sound pressure level (SPL) and improve acoustic response for passive sound amplification, and a mechanical slot to connect smartphones and other apparatuses in a unique, portable and small piece of technology. The internal structure of this invention is designed to house a specially designed thin sound tube, a rechargeable battery, a wireless charging antenna, USB-C power input and USB-A power output ports, a flexible charging cover, a stand for vertical tilted, or horizontal tilted, or landscape, or screen facing up positions, and electronic boards and connectors of the latest technology that manage, interface and/or detect the power obtained from the power source, and charge apparatuses such as a computer, phones, tablets, etc. It can also include speakers, data transfer capabilities among other features. The present invention is a portable hub system which comprises a unitary hub device with an internal power source with the unitary device housing a set of electronics for wireless and wired communications with a computer and other apparatuses. This invention has input buttons to activate internal components and software to transfer power, with a computer, phones, and other apparatuses simultaneously. The device of the present invention includes a port to install phones and other apparatuses for power charging. This invention has a small special thin sound tube specially designed to fit into a small frame which increases the decibels of the connected phones or other apparatuses. This invention includes a mechanical connection on a top surface, and the mechanical connection is capable of securing a functional object and electronically transferring power and the sound waves into this invention's sound tube.
