An eartip, mold device for manufacturing the eartip, and method of manufacturing the eartip are introduced, characterized by forming an upper bevel-portion with upper and lower molds of a first mold unit, placing the upper bevel-portion in an upper bevel receiving cavity of a second mold unit, forming a lower bevel-portion with a lower bevel cavity, and joining the upper and lower bevel-portions to form an eartip. The top of the lower hollow-cored guiding tube extends to form a buffer portion which connects and communicates with the upper hollow-cored guiding tube. The upper and lower bevel-portions are made of silicone of different rigidity. The upper bevel-portion thus made is soft enough to reach a user's ear canal deeply. The lower bevel-portion thus made is rigid enough to close the ear canal. An annular buffer cavity is inwardly, concavely formed at the bottom of the lower bevel cavity.

The present invention discloses a multi-functional mobile phone protection case and a manufacturing method thereof. The multi-functional mobile phone protection case comprises an upper cover, a main case, a screen rubber coating and a back case; the upper cover is installed on top of the main case through a pin; volume keys are provided at the upper left side of the main case; and a mobile phone fixing pad and a rope are provided from top to bottom of the lower left side of the main case, respectively; and a power key, a padlock and a fixing button are provided from top to bottom of the right side of the main case, respectively; back case is installed on rear side of the main case through a bracket locking mechanism; an arm band buckle is fixed to rear side of the back case through a second arm band fixing clip and a first arm band fixing clip, a fabric band is provided on the front end of the arm band buckle; a waterproof earphone plug and a waterproof acoustic transmission film is set up from left to right of the bottom of the upper cover, respectively. Through unique structure and manufacturing process design, the present invention can achieve integration of multiple functions, simple and sensible structure design, and not only waterproof, anti-collision and anti-freezing functions, but also sports adaption, portability and multi-style compatibility.

An in-ear monitor and a method for manufacturing the in-ear monitor from a block of solid medium made from a combination of wood and acrylic and finished with an acrylic coating. The manufacturing process utilizes computerized numerical control techniques to subtractively manufacture the in-ear monitor from the block of solid medium. Acrylic pieces are embedded into the wood randomly or in a desired pattern so that each block has a unique design pattern. Each in-ear monitor is manufactured from a block of solid medium, will therefore, have a unique design pattern as well.

A housing assembly for a mobile device includes a cover formed from optically transmissive material, and opaque material formed over a portion of the cover. The opaque material is arranged to define a display portion which is optically transmissive. The housing assembly further includes a frame sized to receive the cover, and a first housing structured to couple with the frame, such that the cover, the frame, and the first housing are structured to define an enclosure sized to contain electrical components for the mobile device.

An outer cover for an electronic device, such as a portable electronic device, is disclosed. Since portable electronic devices are often portable, they can be damaged, such as scratched, dented, broken, and the like, when transported or used. The outer cover can serve to provide a protective member over part of the housing for the electronic device. The protective member, when placed on the portable electronic device can serve to reduce damage to sides of the portable electronic device. While the outer cover can provide side and/or edge protection, the outer cover need not also provide front or rear protection.

A rotary injection mold for an elastic housing of a neckband headset includes an upper mold core and a lower mold core, the lower mold core is provided with a main installation cavity and a control end installation cavity, the main installation cavity is installed with a rotary mold core having two half-ring molding channels. When the upper mold core and the lower mold core are closed, a primary injection cavity is formed, for molding a supporting member supporting a neckband; a secondary injection cavity is formed, for molding a strip member wrapping the neckband. The control end installation cavity is provided with two control end injection molds for molding a control end elastic casing, and the control end injection cavities are hermetically communicated with the secondary injection cavity. By the invention, an integrated elastic housing is molded to wrap the neckband headset, to improve the manufacturing efficiency.
