An ear tip for use with an earphone is filled with a UV-curable polymer or other material that hardens when energy is applied, fitted to a user's ear, and exposed to UV light or other appropriate energy, curing or otherwise hardening the material and forming a custom-fit ear tip.

Multilayer structure (200) for electronic devices, including a flexible substrate film (102) for accommodating electronics, a number of electrical elements (204, 206) provided to the flexible substrate film, preferably by element of printed electronics and/or surface mounting, a protective layer (104) laminated onto at least first surface of the substrate film, the protective layer being configured to mask perceivable physical deviation of the substrate, such as uneven surface profile or coloring, substantially at the location of the number of elements, from outside perception, optionally visual perception and/or tactile inspection taking place via the protective layer, and plastic layer (106) molded over at least second surface of the substrate film opposite to the first surface. A corresponding method of manufacture is presented.

An ear plug having a pressure-adjusting compartment and a formation method. The ear plug is mounted on an earphone so as to be placed into a human auditory canal. The ear plug employs a first formation step for forming an outer main body, the ear plug further employs a second formation step for forming an inner main body, such that the inner main body has formed thereon a mounting portion and an umbrella portion having at least one second air conducting hole, and the ear plug further employs an integration step to make at least one pressure-adjusting compartment between the mounting portion, the audio out portion, the umbrella portion and the outer wall portion, which is respectively and mutually communicated with the first air conducting hole and the second air conducting hole, thereby balancing air pressures in the human auditory canal and outside the earphone via the pressure-adjusting compartment.

The present disclosure provides a magnetic housing for mobile device and a manufacturing process of the magnetic housing. The magnetic housing includes a housing body, an outer sleeve, a magnetic coil, and an inner lining. The housing body comprises a bearing part and a surrounding part. The surrounding part is connected to and intersecting with an outer periphery of the bearing part to form an accommodating space. The accommodating space accommodates a mobile device. The bearing part comprises a groove. The outer sleeve is disposed on a surface of the housing body away from the accommodating space. The magnetic coil is disposed in the groove. The inner lining is disposed on a surface of the housing body close to the accommodating space. The overall thickness of the housing for mobile device would not be increased when magnetic coils are disposed.

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.

A method of attaching a flexible screen to a cover plate includes: adhering a first adhesive film layer of a laminated adhesive film to a mounting surface of a cover plate, in which the laminated adhesive film includes the first adhesive film layer, a second adhesive film layer and a second release layer, the second release layer is releasably attached to the second adhesive film layer, the first and second release layer are respectively disposed on both sides of the second adhesive film layer; releasing the second release layer from the second adhesive film layer; and adhering the second adhesive film layer to a flexible screen such that the cover plate is attached to the flexible screen. A tight attachment between the laminated adhesive film and the cover plate can be achieved.

The application discloses an a method of forming a lower friction eartip when compared to a pretreated elastomer eartip.

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.
