Abstract

An earphone case includes a shell, a rotating drum received in the shell, a driving assembly coupled to the rotating drum and configured for rotating the rotating drum, and a back cover latchable with the shell and receiving the driving assembly in a receiving space defined therein. The rotating drum is driven by the driving assembly to rotate to wind a wire of at least one pair of earphones.

First claim

What is claimed is:

1. An earphone case comprising:
a shell;
a rotating drum comprising a shaft extending from an end surface of the rotating drum, a shaft hole defined in the shaft, the rotating drum received in the shell;
a driving assembly coupled to the rotating drum; and
a back cover latchable with the shell and receiving the driving assembly in a receiving space defined therein;
wherein a securing groove is defined on a lateral surface of the rotating drum for receiving a pair of earbuds of an earphone;
wherein an accommodating hole is defined extending from an outer surface of the rotating drum toward an interior of the rotating drum for receiving an earphone plug of the earphone; and
wherein the driving assembly comprises a driving arm received in the shaft hole to be coupled with the rotating drum, and the rotating drum is rotatable by the driving arm to wind a wire of the earphone around the rotating drum.

2. The earphone case of claim 1 , wherein the driving assembly comprises a bearing surrounding the shaft.

3. The earphone case of claim 2 , wherein a driving groove is defined in an inner wall of the shaft hole; the driving arm comprises a protruding portion; the protruding portion is embedded in the driving groove to couple the shaft to the driving assembly.

4. The earphone case of claim 3 , wherein the driving assembly comprises a motor and a power source; the motor and the power source are received in the receiving space of the back cover; the back cover comprises a switch, the switch controls the power source to provide power to the motor to drive and rotate the rotating drum.

5. The earphone case of claim 4 , wherein the back cover comprises a closed end and an open end; the switch is arranged on the closed end; the open end is opposite to the closed end and coupled to the shell.

6. The earphone case of claim 5 , wherein the shell comprises a latching assembly; the latching assembly is arranged on an outer surface of the shell and latches with the open end of the back cover to latch the shell to the back cover.

7. The earphone case of claim 6 , wherein the shell comprises an opening; an inner periphery of the opening is larger than an outer periphery of the rotating drum; an accommodation space is defined between the outer periphery of the rotating drum and the inner periphery of the opening when the rotating drum is received in the shell; the accommodation space accommodates the wound earphones therein.

8. The earphone case of claim 7 , wherein the latching assembly is located on each of opposite sides of the shell; the latching assembly comprises a latching member and a resilient member; a latching hole is defined in the open end of the back cover; the latching member is latched in the latching hole to latch the shell to the back cover.

9. The earphone case of claim 8 , wherein a latching groove is defined in each of opposite sides of the shell, the latching groove extends from the opening of the shell toward an end of the shell opposite to the opening; the latching member and the resilient member are received in the corresponding latching groove; the resilient member is compressed by the latching member when the shell is latched with the back cover; the latching member resisted by the resilient member forms an outward protrusion; the outward protrusion is pressed to unlatch the shell from the back cover.
