  • Patent number: 12192698
    Abstract: Loudspeakers are described that may reduce comb filtering effects perceived by a listener by either 1) moving transducers closer to a sound reflective surface (e.g., a baseplate, a tabletop or a floor) through vertical (height) or rotational adjustments of the transducers or 2) guiding sound produced by the transducers to be released into the listening area proximate to the reflective surface through the use of horns and openings that are at a prescribed distance from the reflective surface. The reduction of this distance between the reflective surface and the point at which sound emitted by the transducers is released into the listening area may lead to shorter reflected path that reduces comb filtering effects caused by reflected sounds that are delayed relative to the direct sound. Accordingly, the loudspeakers shown and described may be placed on reflective surfaces without severe audio coloration caused by reflected sounds.

  • Patent number: 10897662
    Abstract: An assembly (1) for protecting an acoustic device comprises an expanded polytetrafluorethylene (ePTFE) membrane (3) and first and second polymeric substrates (2, 4) disposed on opposing sides (5, 6) of the membrane (3). The first substrate (2) is transmissive for laser light of a predetermined wavelength, and the membrane (3) is joined to the first and second substrates (2, 4) by first and second laser weld joints (9, 10) on the first side (5) of the membrane (3) and the second side (6) of the membrane (3), respectively, that are created in a single laser transmission welding step through the first polymeric substrate (2) towards the second polymeric substrate (4). The first side (5) of the membrane (3) may be at least partially absorbent for the laser light and the second side (6) may be at least partially transmissive for the laser light. This may be achieved by a color gradient from black to white from the first side (5) to the second side (6).
