Abstract
A cell phone protective case, with expander of sound outlet located on the right and left sides and the bottom perimeters, of a cell phone is invented. The frame interior is comprised of a circular throat member for sound impedance, matching to create an improved coupling effect between the original speaker, and the air, where the frame interior is comprised of sectional chambers covering both the horizontal and vertical coverage axis' to change the directional characteristics of sound waves to amplify and channel the sound en route towards the outer perimeters of the device.

A sound-amplifying cell phone case for a cell phone with a sound outlet located on the right and left side and the bottom perimeters, the cell phone case comprising:
- a cover case for enclosing and covering a rear portion of the cell phone;
- a circular throat member provided in a frame interior to cover the sound outlet for sound impedance, matching to create an improved coupling effect between the original speaker and the air;
- sectional chambers covering both the horizontal and vertical coverage axis' to receive and change the directional characteristics of sound waves from the circular throat member to amplify and channel the sound en route towards the outer perimeters of the device;
- and
- a spring disposed between the cover case and the rear portion of the cell phone for having the cover case opened at a specific angle,
- wherein the cover case pops up when pressed down, as the spring sustains the cover case when compressed and expanded,
- wherein the cover case further comprises a pair of gripping corner portions provided at two corners at the opening end for holding two corresponding corners of the cellular phone so as to close the cover case overcoming the opening force of the spring.
An expandable and collapsible sound-amplifying case for a cellular phone having a sound outlet of a speaker and a camera lens, the case comprising:
- a cover case having a fixing end configured to be attached to a top edge of the cellular phone and an opening end configured to be opened and closed with the fixing end as a hinge;
- a sectional chambers attached to an inner surface of the cover case and a rear surface of the cellular phone and disposed between the fixing end of the cover case and the opening end and configured to receive, guide toward the opening end, and amplify sound wave from the sound outlet of the cellular phone;
- and
- a spring installed between the inner surface of the cover case and the rear surface of the cellular phone and configured to open the cover case,
- wherein the cover case is opened with a specific angle determined by interplay of an opening force of the spring and a limiting force of the sectional chambers attached to the inner surface of the cover case and the rear surface of the cellular phone,
- wherein the cover case is configured to be closed,
- wherein the cover case further comprises a pair of gripping corner portions provided at two corners at the opening end for holding two corresponding corners of the cellular phone so as to close the cover case overcoming the opening force of the spring.
