Abstract: A speaker horn with rotatable radiation characteristics has a base body in the form of an opening funnel with a rotationally symmetrical inner wall in the radiation area and an insert mounted so that it can rotate relative to the base body. The insert covers part of the rotationally symmetrical inner wall acoustically and causes the rotatable radiation characteristic of the speaker horn.

Abstract: A method for identifying the position of loudspeaker boxes in a loudspeaker box arrangement includes the operation of a first loudspeaker box in the loudspeaker box arrangement as an acoustic test signal generator. An acoustic test signal from the first loudspeaker box is received at other loudspeaker boxes in the loudspeaker box arrangement. A positional relationship between the signal-generating first loudspeaker box and at least one of the other loudspeaker boxes in the loudspeaker box arrangement is ascertained on the basis of the acoustic test signal received in the other loudspeaker boxes.

Abstract: An acoustic transducer may comprise a sound source, a throat connected to the sound source, and a horn connected to the throat. The horn may be arranged on a wall, wherein the throat is designed such that a path of the sound from the sound source to an interface between the throat and the horn is shorter in a region close to the wall than at a region that is remote from the wall.

Abstract: A loudspeaker box (300) has a loudspeaker housing (1) and a sound source (3a) with a non-rotationally symmetrical radiation characteristic. The sound path of the sound source (3a) contains an acoustic element (4) which dilates or constricts the radiation of sound in at least one radiation plane. The loudspeaker box (300) comprises a mechanism which can be used to position the sound source (3a) and the acoustic element (4) in different rotational positions relative to one another.

Abstract: An electrically conductive substrate is provided with a predetermined electrical pattern. A solder paste is deposited onto the electrically conductive substrate at pre-defined interconnection locations. A first encapsulant layer provided with a pattern of openings is placed onto the electrically conductive substrate. Back-contact solar cells are placed on the first encapsulant layer so as to have a match of the electrical pattern of the back-contact solar cells with the electrical pattern of the electrically conductive substrate. A second encapsulant layer is placed on the back-contact solar cells with a glass layer placed on the second encapsulant layer. Heat and pressure are applied to the components to cause the encapsulant materials to flow and form a monolithic photovoltaic module. A laser is applied to the solar cell from the side of the glass layer to cause the solder paste to reflow between each interconnection location and its matching connection location on the back-contact solar cell.

Abstract: An attachment apparatus for forming an arrangement comprising a plurality of loudspeaker boxes hanging one above the other comprises a latching connection by means of which two loudspeaker boxes which are adjacent in the arrangement can be connected together at a pre-selectable angle.

Abstract: An electrical component includes a base object made of two insulating objects with curved external surfaces, and external electrodes. Each of the external electrodes is disposed adjacent to one of the two insulating objects. A central electrode is disposed inside of the base object. The central electrode includes a flat mounting surface on an exterior of the component.

Abstract: Latching connection for an arrangement comprising a plurality of loudspeaker boxes hanging one above the other An attachment apparatus for forming an arrangement comprising a plurality of loudspeaker boxes hanging one above the other comprises a latching connection (25, 26) by means of which two loudspeaker boxes (2) which are adjacent in the arrangement can be connected together at a preselectable angle.

Abstract: The invention relates to a connecting unit for the angle-adjustable connection of at least two loudspeaker enclosures. There are provided a first supporting part (13), which can be assigned to one loudspeaker enclosure (11), and a second supporting part (14), which can be assigned to the other loudspeaker enclosure (12), it being the case that the supporting parts (13, 14) are connected to one another in an articulated manner, and the angle position assumed in each case between the two supporting parts (13, 14) is fixed in an adjustable manner by an angle-position device (15) which acts in the manner of a turnbuckle.

Abstract: The invention relates to an electrical component with a base object (3), which comprises two insulating objects (1 and 2) with curved external surfaces, each having an external electrode (4 and 5) disposed on its face, in which a central electrode (7) is disposed along a shell surface in a central section (6) of the base object, and in which the central electrode (7) features a flat mounting surface (8) on the exterior of the component. The invention also relates to an arrangement of the component. Furthermore, the invention relates to a method for manufacturing the arrangement. Because of the flat mounting surface (8) on the central electrode (7), the component can be effectively prevented from rolling away from the surface of a printed circuit board (10). In addition, the holding surface (9) permits the suction holding of the component using a suction nozzle (11).

Abstract: In order to be able to produce an electrically conductive, positive connection between an end electrode of a gas-filled discharge path and a lead more simply in fabrication-oriented terms, the raised terminal region, which is provided at the end electrode, is provided with a blind hole into which the one end of the lead is introduced and joined thereat to the terminal region with a laser welding.
