    Abstract: The present disclosure generally provides an apparatus and method of forming a liquid impermeable sealed audio speaker that can be easily manufactured and provides a high quality audio output. In an effort to overcome the shortcomings of conventional sealed speaker designs that typically utilize complicated and expensive means of shielding their electronic components from liquids and other sources of contamination, one or more of the embodiments of the disclosure provided herein include a sealed enclosure that has at least one liquid impermeable region that prevents or substantially inhibits the movement of a liquid from the exterior region into the internal region. In general, the liquid impermeable regions, or hereafter simply “liquid permeable regions,” are configured to prevent the ingress of liquids or other contaminants, while allowing the production of a desired sound quality.

    Abstract: The invention relates to a programmable digital sound reproduction system (10), comprising a controller (12) and a plurality of active loudspeaker chassis (14) connected to the controller (12) for communication purposes, wherein the controller (12) has an interface (16) for receiving digital sound data (18) from a sound source (20), a sound data processing unit (22) for processing the digital sound data (18) to produce at least one piece of digital sound information (24), and a distributor (26) for distributing the digital sound information (24) to an active loudspeaker chassis (14), connected to the controller (12) for communication purposes, from the plurality of active loudspeaker chassis (14), the plurality of active loudspeaker chassis (14) each have a receiver (28) for receiving the corresponding digital sound information (24) distributed by the controller (12) to an active loudspeaker chassis (14) from the plurality of active loudspeaker chassis (14), an amplifier (30) for amplifying and forwarding the digital sound information (24), and a sound transducer (32) for converting the digital sound information (24) into alternating sound pressures (34). In accordance with the invention, a program-controlled signal processor (36) for specific processing of the received digital sound information (24) is arranged in each active loudspeaker chassis (14) from the plurality of active loudspeaker chassis (14). In this way, a programmable digital sound reproduction system (10) is described with which a high sound quality is made possible.

    Abstract: A speaker system may include a speaker enclosure with a front wall having an acoustic port formed therein and toward a bottom thereof, with the acoustic port being shaped such that air exiting the acoustic port flows outwards in a direction parallel to the bottom. In addition, the front wall of the speaker enclosure may be shaped so as to define a plurality of hills and valleys on an inwardly facing surface thereof. A grill may be positioned over the front wall of the speaker enclosure, the grill being shaped so as to define a plurality of valleys on an outwardly facing surface thereof, the plurality of valleys having semi-cylindrical shaped cross sections. The plurality of valleys defined by the grill may have a plurality of holes defined therein, and the plurality of holes having parabolic shaped cross sections.
