A hinge assembly comprises a first connecting member, a second connecting member, a first shaft, a second shaft, and a clockwork spring. The first connecting member includes a first pivot portion. The second connecting member includes a second pivot portion. The first shaft is pivotally connected to the first pivotal portion of the first connecting member and the second pivotal portion of the second connecting member. The second shaft is configured on the first connecting member and spaced from the first shaft. The clockwork spring includes a first end and a second end away from the first end; the first end fixed to the second shaft rod, the second end fixed to the second connecting member. When the second connecting member pivots with respect to the first connecting member, the arrangement of the clockwork spring can provide a more stable pivoting force for the second connecting member.

An earbud includes a housing that includes a driver assembly positioned within the housing forming a front volume in front of the driver and a back volume behind the driver. An acoustic insert is positioned behind the driver assembly and attached to an interior surface of the housing such that it forms a bass channel that is routed from the back volume to a vent in the housing.

An expandable device for use with a portable electronic device includes a body, a button, a platform, and a locking device. The body has a first end, a second end, and a longitudinal axis, and is movable between an expanded configuration and a collapsed configuration. The button is coupled to the first end of the body, and the platform includes an outer surface and a collar extending away from the outer surface. The collar defines a cavity. The locking device is carried by the second end of the body, and at least a portion of the locking device is adapted to be removably disposed in the cavity of the platform for releasably coupling the body to the platform. The locking device is rotatable relative to the platform between an unlocked configuration, in which the body is removable from the platform, and a locked configuration, in which the body is secured to the platform.

Disclosed is a cover including a receiving portion having a space defined for receiving an electronic device, a covering portion, and a hinge portion connecting the receiving portion and the covering portion and allowing the covering portion to pivot. The covering portion includes, in a state in which the covering portion is pivoted in a specified direction about the hinge portion to at least partially cover the space, a light guiding member disposed on the first surface for guiding light, and an outer cover layer disposed on a second surface opposite to the first surface. In addition, various embodiments understood through the specification are possible.

A rotation mechanism includes a base, a rotation plate, and an elastic element. The base has two base side walls opposite to each other, an accommodation space between the two base side walls, an abutting portion, and two pivot portions opposite to each other. The abutting portion is located at one end of the base side walls, and the pivot portions are respectively located at the other end of the base side walls. The rotation plate is pivotally connected to the base and between the pivot portions. The elastic element has a first pivot section, an elastic bending section, and a second pivot section that are sequentially connected to each other. The first pivot section is pivotally connected to the two base side walls, and the second pivot section is pivotally connected to one side of the rotation plate.

A case for a mobile, electronic device, the case having a hard, clear case body with an outer surface and an inner surface facing the electronic device and at least one separator on the inner surface of the case body to create a space between the electronic device and the case body.

An outer case for covering a handheld electronic device or handheld electronic device case includes a base, a lid, and a collar. The lid is pivotably attached to the base. The collar is attached to the base and is moveable away from the lid such that the lid rotates away from the base during movement of the collar away from the lid.

A protective case system for use with an electronic device includes a protective case, a handle, and an adapter. The protective case removably receives the electronic device and a display screen of the electronic device remains accessible when the electronic device is installed in the protective case. The handle is attached to and extends outward from a back surface of the protective case. The handle is configured for carrying the protective case and the installed electronic device. The adapter is configured to be removably attachable to the handle and bendable by a user to a plurality of positions. The adapter is configured to function as a multi-position stand for the protective case and the installed electronic device. The adapter is further configured to removably affix the protective case and the installed electronic device to headrest posts of a seat.

The present invention relates to a bag or case used to store and carry a microphone stand. Most of the microphone stand carry bags are only suitable to carry the boom and poles of the stand and are not designed for the stand base which is mostly circular and perpendicularly attached to the microphone stand poles. The portable microphone stand bag of present invention resolves the above described problems and provides better user experience. The portable microphone stand bag of present invention includes assembly that consists of an upper compartment and a lower compartment. The advantage of the present invention is that the microphone stand, and the base can be securely stored and carried to any location with ease and comfort. The unique upper and lower compartment of the bag provides an equally distributed balanced load and makes it easy to carry the bag.

A protective case for a mobile device having a multi-layered construction is disclosed herein. The protective case includes a flexible inner sleeve for conformingly surrounding the mobile device and a rigid shell for engaging the flexible inner sleeve. The flexible inner sleeve conforms to, and encapsulates, the mobile device. The rigid shell receives and engages the inner sleeve. The flexible inner sleeve and the rigid shell may be used separately or may be used as an integrated protective unit to protect a mobile device.
