This disclosure provides a waterproof structure of an electronic device having a box, a cable, a sealant, and a cover. The box has an opening and a groove defined on the box along an edge of the opening, the groove is extended in a closed curve manner, and an outer through opening communicated with the groove is defined on an external surface of the box and the groove has an inner through opening communicated with an internal space of the box. An outer baffle and an inner baffle respectively corresponding to the outer and the inner through opening are arranged on the cable, the cable penetrates the box through the outer and the inner through opening, and the outer and the inner baffle respectively close the outer and the inner through opening. The sealant is filled in the groove. The cover body covers the opening and closes the groove.

Certain exemplary embodiments relate to entertainment systems and, more particularly, to systems that incorporate digital downloading jukebox features and improved user interfaces. For instance, a smart search may be provided, e.g., where search results vary based on the popularity of songs within the venue, in dependence on songs being promoted, etc. As another example, a tile-based approach to organizing groupings of songs is provided. Groupings may involve self-populating collections of songs that combine centrally-promoted songs, songs in a given genre that are popular across an audiovisual distribution network, and songs that are locally popular and match up with the given genre (e.g., because of shared attributes such as same or similar genre, artist, etc.). Different tile visual presentations also are contemplated, as are different physical jukebox designs. In certain example embodiments, a sealed core unit with the “brains” of the jukebox is insertable into a docking station.

The electric device has a first seal part, including, between a first case and a second case, a groove portion prepared at one side and a projection portion prepared at another side, where those portions are joined by sealing material; a second seal part, including, between the opening part of the first case and a peripheral part of the connector, a groove portion prepared at one side and a projection portion prepared at another side, where those portions are joined by the sealing material; and a third seal part, including, among the first case, the second case, and the peripheral part of the connector, a groove portion prepared at one side and a projection portion prepared at another side, as a combination, or a projection portion prepared at one side and a groove portion prepared at another side, as a combination, where those portions are joined by the sealing material.

Provided is an information output apparatus including a casing including an expression surface and an expression hole formed in the expression surface, a protrusion provided to reciprocate such that at least a part thereof protrudes out of the expression hole and information is expressed on the expression surface, and a driving module located inside the casing and connected to the protrusion to move the protrusion.

An electric circuit board includes an insulating substrate, a metal plate, and a brazing material with which the insulating substrate and the metal plate are joined together. The metal plate has a side surface over which recessed portions are scattered. The side surface of the metal plate has lines in regions around the recessed portions. The metal plate is made of copper or a copper alloy. The brazing material has a side surface that is continuous with the side surface of the metal plate. The brazing material is a silver-copper brazing alloy. A ratio of copper on the side surface of the brazing material is higher than a copper component ratio of the silver-copper brazing alloy.

A metal enclosure for electrical components may include a rear panel and four side panels coupled with adhesive to form a bonded case having a cavity with a front opening. Channels of the four side panels may be joined to form a case channel circumscribing the opening. The case channel may be recessed towards a center of the opening so as to not extend radially beyond an envelope formed by planes of main panes of the four side panels of the one of the two adjoined panels or the one of the two separate panels. A door may be hingedly connected to one of the four side panels and may have one or more latches installed thereon. When the door is closed, a gasket engages a main panel of the door and a front surface of the case channel to seal the metal enclosure.

An electronic device having at least one circuit board. The circuit board has a predetermined pattern of solder bumps facilitating a ground connection with a first enclosure member and/or a second enclosure member. The at least one circuit board is sandwiched between the first and second enclosure members, each of the first and second enclosure members has a surface facing the circuit board and the surface facing the circuit board has a bead extending therefrom contacting the predetermined pattern of solder bumps to complete the ground connection.

A circuit assembly is provided and includes a printed circuit board (PCB) having a circuit element region and defining a trench surrounding an entirety of the circuit element region, a circuit element disposed within the circuit element region of the PCB; and a Faraday wall. The Faraday wall includes a solid, unitary body having a same shape as the trench. The Faraday wall is disposed within the trench to surround an entirety of the circuit element.
