An example method of operation includes identifying a venue geometry from a stored value, determining a venue polar representation based on the venue geometry, selecting one or more loudspeaker types to place in the venue based on the venue geometry and one or more target sound pressure levels (SPLs), selecting one or more locations in the venue to place the one or more loudspeakers, identifying one or more angles to position the one or more loudspeakers in the venue at the selected locations, and generating a display model of a loudspeaker arrangement comprising a selected number of speakers and one or more filters to apply to the one or more loudspeakers.

Loudspeaker array passive acoustic configuration procedure

A method that improves the energy distribution from a multi-way loudspeaker into free space. The method reduces MF energy through the use of small depressurizing slit openings down the inner half of the HF stems. The openings are sized to be large enough to present a leak path for the secondary energy to migrate out of the stem with no return path.

Embodiments are disclosed for a loudspeaker for producing directed acoustic vibrations. In some embodiments, a loudspeaker includes an electromagnetic transducer including a diaphragm configured to generate acoustic vibrations. The loudspeaker may further include an aperture frame positioned in front of the diaphragm in a direction of propagation of the acoustic vibrations, the aperture frame covering only a portion of a radiating surface of the diaphragm and having a shape that corresponds to the contours of the diaphragm.

Techniques are disclosed for an audiovisual system having a display screen that is solid and/or otherwise non-transparent to sound. The sound output from a loudspeaker is oriented to intersect with a portion of the display screen, and a reflection of the sound off of the display screen is directed toward a viewing position in the audiovisual system. Further signal processing techniques to generate sound for output by a loudspeaker oriented at the display screen and other loudspeakers are disclosed. Additionally, other signal processing and control techniques are disclosed that affect audio and video output in the audiovisual system.

A loudspeaker may include a full-range waveguide for creating a unified wavefront. The waveguide may include a plurality of entrances, which may be positioned at a first axial end. The waveguide may include a mouth disposed at a second axial end opposite the plurality of entrances. A contoured surface extending between the entrance and the mouth defines a cavity within the waveguide. The contoured surface may include a first pair of walls positioned opposite one another and a second pair of walls positioned opposite one another. The waveguide may include at least one integrator disposed in the cavity between two adjacent entrances. Each integrator may extend transversely between the first pair of walls and may taper towards the mouth to form a pointed edge extending between the first pair of walls. A pair of integrator surfaces each include a solid portion and a perforated portion.
