  • Patent number: 10524079
    Abstract: A directivity adjustment device that includes a test sound signal generator, a surface detector, and a content processor is described. The test sound signal generator generates test sound signals to scan a listening area (e.g., a room) in a nodding and rotating fashion. The test sounds are emitted by one or more loudspeaker arrays and are sensed by a microphone as they permeate throughout the listening area. The sensed sound is analyzed by the surface detector, to identify reflected sounds in relation to direct sound. Based on the amplitude variance between the peaks that represent the direct and reflected sounds reaching a predefined threshold, an adjusted directivity ratio for the content processor is selected or calculated, which results in a reduction of the level of reflected sounds and corresponding comb filtering effects. Other embodiments are also described.

  • Patent number: 10021479
    Abstract: A speaker producing total sound immersion by directing the sound in off-horizontal directions, and directing sound in different frequency ranges in different directions. The low range driver, or woofer, is oriented downward, and fitted with a dispersion plate, which deflects the sound along the floor and up into the room. The high range drivers, or tweeters, are oriented upward and set for wide dispersion, so that the high pitched sound is reflected off the ceiling and is more evenly distributed. One midrange driver is set in each side of the speaker box, and the sides are angled, so that the box is in the form of a truncated pyramid. This causes the midrange sound to be reflected off the walls and ceiling of the room. The result is one speaker producing a total sound immersion effect.

The sound waves comprise sound waves of a first frequency that radiate according to a first radiation pattern and sound waves of a second frequency that radiate according to a second radiation pattern that is less directed along an axis of the audio driver than the first radiation pattern. The second frequency is lower than the first frequency. The acoustic filter is configured to attenuate the sound waves of the first frequency so that the attenuated sound waves of the first frequency are emitted from the acoustic filter according to an effective radiation pattern that is less directed along the axis of the audio driver than the first radiation pattern and pass the sound waves of the second frequency in substantial accordance with the second radiation pattern.

  • Publication number: 20120237069
    Abstract: An electrostatic loudspeaker (ESL) assembly providing curvature in two directions for improved dispersion of sound waves. The ESL comprises at least one stator panel, a flexible diaphragm and a spacer that impedes contact between the stator panel and the diaphragm. The stator is formed from a material that comprises an array of apertures. Furthermore, the material can be annealed. The material temper, along with the aperture geometry and patter, affect the stretchability of the material. The two-axis curved structure enables a compact form of ESL to be realized, including bookshelf type loudspeakers whereas all known commercial units are comparable in height to that of a human listener. The individual curved ESL panels can also be readily combined to create larger transducer assemblies including omni-directional units.

  • Patent number: 8259980
    Abstract: An adjustable tweeter assembly is provided to allow a tweeter to be directionally oriented to a selected position. The assembly includes a base, a bowl, and a cup, which are nested together so that the bowl is sandwiched between the base and the cup for movement therebetween. The tweeter is mounted in the bowl which can be rotated and pivoted relative to the cup and to the base. A fastener extends through the cup, the bowl, and the base, and through a leaf spring so as to provide a compressive or clamping force between the base, the bowl, and the cup. The tweeter is rotatable 360° and pivotal approximately 90°.

  • Patent number: 8224001
    Abstract: A line array speaker provides highly uniform frequency response throughout a wide listening field, while also reducing distortion and improving fidelity, clarity, and output level. In a symmetrical embodiment, central apertures are straddled by a sequential pairs of sets of apertures. The straddling pairs emit frequencies in the next lower frequency band relative to the frequency band of the immediately preceding frequency band apertures. In an asymmetrical embodiment, sequential frequency bands are emitted by adjacent sets of apertures rather than straddling pairs of sets of apertures. Each of the apertures may be a loudspeaker cone, one or more straight slots, one or more arbitrarily curved slots, one or more arbitrarily angled slots, one or more holes or the mouth of a horn. The speaker may have a front baffle which is a flat panel or multiple facets arranged in one or multiple recesses across a front of the speaker.

  • Patent number: 8175304
    Abstract: A loudspeaker configuration capable of generating stereophonic sound separation from relatively loudspeaker drivers that are not necessarily widely separated. For example, such a loudspeaker configuration can be used to generate relatively good sound separation from a single chassis, such as a single speaker box, a boom box, a clock radio or the like. This can advantageously save space in many environments. One embodiment uses four mid-tweeter speaker drivers and a bass driver. The four mid-tweeter speaker drivers are arranged facing outward approximately 90 degrees apart from each other. A speaker driver facing the listener reproduces a mid channel signal, for example, L+R. A speaker driver facing away from the listener reproduces the same mid channel signal or a delayed version of the mid channel signal. A left facing speaker reproduces a side channel, for example, L?R. A right facing speaker reproduces a side channel, for example, R?L.

  • Patent number: 8170223
    Abstract: A loudspeaker is provided for receiving an incoming electrical signal and transmitting an acoustical signal that is directional and has a substantially constant beamwidth over a wide frequency range. The loudspeaker may include a curved mounting plate that has curvature over a range of angles. The loudspeaker may include an array of speaker drivers coupled to the mounting plate. Each speaker driver may be driven by an electrical signal having a respective amplitude that is a function of the speaker driver's respective location on the mounting plate. The function may be a Legendre function. Alternatively, the loudspeaker may include a flat mounting plate. In this case, the respective electrical signal driving each speaker may have a phase delay that virtually positions the speaker onto a curved surface.

  • Patent number: 8130976
    Abstract: A sound system which has, for example, a radio, a cassette and a CD player is usually already installed in cars as standard or as an option. In addition, a better sound system includes a box system which has a tweeter and a woofer. In order to provide a speaker box which is suitable particularly for dispensing frequencies below 150 Hz and at the same time has neat pulses accompanied at the same time by little distortion, pulse dynamics and is highly effective, a sound transducer (10) is introduced into the supporting structure of the vehicle. This takes place in such a manner that subcompartments which are separated from each other adjoin each of its two membrane sides. In this case, the two subcompartments of the speaker box are formed by at least two elements (2, 3, 4) of the supporting structure of the vehicle (1).
