Abstract

Speaker power systems can provide electricity to an audio speaker device that does not have an internal battery to transform the speaker device from a power-outlet dependent device to a mobile device. Speaker power systems can include a housing configured to couple to a lower portion of the speaker device, a battery located in the housing, and an electrical cable configured to provide the electricity from the battery to the speaker device.

Claims

1. A speaker power system configured to provide electricity to an audio speaker device that does not have an internal battery configured to enable playing music, the speaker power system comprising:

a housing configured to couple to a lower portion of the speaker device;

a battery located in the housing; and

a first electrical cable configured to provide the electricity from the battery to the speaker device to transform the speaker device from a power-outlet dependent device to a mobile device.

2. The speaker power system of claim 1, further comprising a cylindrical clamp having at least a first sidewall, a second sidewall, and a third sidewall,

wherein the sidewalls are separated from each other by openings configured to allow the sidewalls to flex outward in response to inserting the lower portion of the speaker device into an area between the sidewalls,

wherein the cylindrical clamp is configured such that the sidewalls flexing outward creates a compressive force on the lower portion of the speaker device to mechanically couple the speaker power system to the speaker device.

3. The speaker power system of claim 2, wherein the cylindrical clamp couples to a vertical sidewall of the speaker device such that at least 75 percent of the sidewall of the speaker device is located outside of the speaker power system.

4. The speaker power system of claim 2, further comprising a cylindrical liner located in the area between the sidewalls such that the cylindrical liner is compressed between the sidewalls and the speaker device when the lower portion of the speaker device is located in the area between the sidewalls.

5. The speaker power system of claim 4, wherein the sidewalls are molded from a first material, and the cylindrical liner is molded from a second material that is softer than the first material such that the cylindrical liner is configured to conform to exterior features of the speaker device, and the sidewalls are configured to maintain a compressive force on the cylindrical liner and the speaker device to prevent the speaker power system from falling off the speaker device.

6. The speaker power system of claim 1, wherein the housing is cylindrical and comprises a cylindrical sidewall that extends upward around the lower portion of the speaker device, the system further comprising a cylindrical liner located adjacent to an interior surface of the sidewall, and located between the sidewall and the lower portion of the speaker device,

wherein the sidewall is molded from a first material, and the cylindrical liner is molded from a second material that is softer than the first material such that the cylindrical liner is configured to deform in response to inserting the lower portion of the speaker device into an interior area of the cylindrical liner, wherein deformation of at least a portion of the cylindrical liner creates a compressive force on the speaker device to prevent the speaker power system from falling off the speaker device.

7. The speaker power system of claim 6, wherein the liner comprises at least two ribs that protrude at least one of radially inward and radially outward, the speaker power system couples to a sidewall of the speaker device, and the speaker power system is configured such that at least 75 percent of the sidewall of the speaker device is located outside of the speaker power system.

8. The speaker power system of claim 6, wherein the first electrical cable comprises a flexible portion that is at least 20 millimeters long, the flexible portion protruding from a lid of the housing, wherein the lid is located between the cylindrical liner and the battery, the first electrical cable passes through a first channel in the lid, the first electrical cable passes through a second channel in the cylindrical liner, and a distal end of the first electrical cable comprises an electrical plug coupled with an electrical port of the speaker device inside the interior area of the cylindrical liner such that the electrical plug is hidden between the speaker power system and the speaker device.

9. The speaker power system of claim 1, wherein the housing comprises sidewalls that extend upward away from the housing and from the battery such that the sidewalls are configured to wrap at least partially around an outer perimeter of the speaker device,

the sidewalls are separated from each other by openings configured to allow the sidewalls to flex outward in response to inserting the lower portion of the speaker device into an area between the sidewalls, and

the sidewalls cover less than 25 percent of the outer perimeter of the speaker device such that at least a majority of sound exit holes of the speaker device are not covered by the speaker power system.

10. The speaker power system of claim 9, wherein the openings are vertical slots such that a distance between adjacent sidewalls is less than 15 millimeters, and wherein the sidewalls are curved to form a cylindrical shape.

11. The speaker power system of claim 9, further comprising a cylindrical liner that wraps around the outer perimeter of the speaker device such that the cylindrical liner is compressed between the sidewalls and the speaker device in the area between the sidewalls.

12. The speaker power system of claim 11, wherein the sidewalls are molded from a first material, and the cylindrical liner is molded from a second material that is softer than the first material such that the cylindrical liner is configured to conform to response to being compressed between the sidewalls and the speaker device, and the sidewalls are configured to maintain a compressive force on the cylindrical liner and the speaker device to prevent the speaker power system from falling off the speaker device.

13. The speaker power system of claim 11, wherein the housing comprises a cylindrical outer wall that wraps around a perimeter of the housing, the sidewalls are located around the perimeter of the housing, and the battery is located within the cylindrical outer wall under the cylindrical liner.

14. The speaker power system of claim 13, wherein the housing further comprises a lid located between the cylindrical liner and the battery, the first electrical cable passes through a first channel in the lid, the first electrical cable passes through a second channel in the cylindrical liner, and a distal end of the first electrical cable comprises an electrical plug coupled with an electrical port of the speaker device inside the area between the sidewalls such that the electrical plug is hidden between the speaker power system and the speaker device.

15. The speaker power system of claim 1, wherein the housing comprises sidewalls that extend upward away from the housing to form a cylindrical clamp such that the sidewalls wrap at least partially around an outer perimeter of the speaker device to apply a compressive force on the outer perimeter of the speaker device to removably couple the speaker power system to the lower portion.

16. The speaker power system of claim 15, wherein the sidewalls are separated from each other by openings,

the speaker power system further comprising a cylindrical liner that wraps around the outer perimeter of the speaker device such that the cylindrical liner is compressed between the sidewalls and the speaker device,

wherein the sidewalls are molded from a first material, and the cylindrical liner is molded from a second material that is softer than the first material such that the cylindrical liner is configured to conform to response to being compressed between the sidewalls and the speaker device, and the sidewalls are configured to maintain the compressive force on the cylindrical liner and the speaker device to prevent the speaker power system from falling off the speaker device,

wherein the liner comprises at least one rib that protrudes radially outward into at least one of the openings such that the rib is configured to prevent the liner from rotating relative to the housing.

17. The speaker power system of claim 15, the system further comprising an electrical port located on an outer surface of the housing and configured to be electrically coupled to a power supply cable that provides the electricity to the speaker power system, wherein the electrical port is electrically coupled to a power control system located within the housing, wherein the power control system electrically couples the battery and to the speaker device.
