20090060236 | LOUDSPEAKER ARRAY PROVIDING DIRECT AND INDIRECT RADIATION FROM SAME SET OF DRIVERS - An array loudspeaker includes a plurality of drivers arranged in an array configuration. A digital signal processor-based control system processes direct audio signal and indirect audio signal inputs for the loudspeaker to simultaneously produce direct sound in the form of a directed beam or wavefront, and indirect sound as a perceptually diffuse soundfield. | 03-05-2009 |
20110150247 | System and method for applying a plurality of input signals to a loudspeaker array - According to one embodiment of the present invention, an electronic device comprises: A housing, the housing further comprising a first surface; A sound producing transducer array further comprising a plurality of sound producing transducers; the sound producing transducer array being located on the first surface of the housing; a first set of input audio signals being applied to the sound producing transducers when the electronic device is in a first spatial orientation; and a second set of input audio signals being applied to the sound producing transducers when the electronic device is in a second spatial orientation. | 06-23-2011 |
20120014544 | BIPOLAR SPEAKER WITH IMPROVED CLARITY - A forward focused bipolar loudspeaker system includes a front-facing driver array and a rear facing driver array with substantially identical front-facing and rear-facing midrange or mid-bass drivers voiced and driven so that the measured SPL curves of each of the arrays, when measured individually, are tonally balanced. The front array and rear array have substantially identical on-axis and off axis frequency response and the rear array's output power (SPL) is reduced by, preferably, about 6 dB with respect to the output power produced by the front-facing array, while retaining a flat tonal balance for both the front and rear speakers, to produce a sound power ratio of about 2:1 as measured by comparing the front and back SPL levels of the speakers. This bipolar speaker system and method for voicing was discovered to provide greater clarity and improved localization while retaining the spacious envelopment of the bipolar sound field. | 01-19-2012 |
20120155679 | LOUDSPEAKER SYSTEM FOR REPRODUCING MULTI-CHANNEL SOUND WITH AN IMPROVED SOUND IMAGE - A loudspeaker system for reproducing multichannel sound with an improved sound image in a listening zone is disclosed. The loudspeaker system includes a first speaker array for location in a first position relative to the listening zone and a second speaker array for location in a second position relative to the listening zone. The first speaker array includes a first radiating lobe for radiating first sound of the multichannel sound and at least a second radiating lobe for radiating a delayed version of the first sound. The second speaker array includes a first radiating lobe for radiating second sound of the multichannel sound, and at least a second radiating lobe for radiating a delayed version of the second sound. The loudspeaker system includes means for modifying the radiating or polar pattern associated with each radiating lobe; wherein the system is arranged such that a listening position substantially equidistant from the first and second arrays is exposed to radiation from the second lobes or from the first lobes and a listening position not substantially equidistant from the first and second arrays is exposed to radiation from both the first lobe of one array and the second lobe of the other array such that substantially all positions in the listening zone receive sound radiation from the first and second arrays with substantially equal arrival times. | 06-21-2012 |
20120237062 | APPARATUS AND METHOD FOR CALCULATING DRIVING COEFFICIENTS FOR LOUDSPEAKERS OF A LOUDSPEAKER ARRANGEMENT FOR AN AUDIO SIGNAL ASSOCIATED WITH A VIRTUAL SOURCE - An apparatus for calculating driving coefficients for loudspeakers of a loudspeaker arrangement for an audio signal associated with a virtual source includes a multi-channel renderer. The multi-channel renderer calculates driving coefficients for loudspeakers of the loudspeaker arrangement based on a first calculation rule, if a position of the virtual source is located outside the loudspeaker transition zone. Further, the multi-channel renderer calculates driving coefficients for loudspeakers of the loudspeaker arrangement based on a second calculation rule, if a position of the virtual source is located within the loudspeaker transition zone. A border of the loudspeaker transition zone includes a minimal distance to a loudspeaker of the loudspeaker arrangement depending on a distance between the loudspeaker and a loudspeaker adjacent to this loudspeaker. Further, the loudspeaker arrangement includes at least two pairs of adjacent loudspeakers with different distances between the loudspeakers of the respective pair of loudspeakers. | 09-20-2012 |
20120237063 | APPARATUS AND METHOD FOR CALCULATING DRIVING COEFFICIENTS FOR LOUDSPEAKERS OF A LOUDSPEAKER ARRANGEMENT AND APPARATUS AND METHOD FOR PROVIDING DRIVE SIGNALS FOR LOUDSPEAKERS OF A LOUDSPEAKER ARRANGEMENT BASED ON AN AUDIO SIGNAL ASSOCIATED WITH A VIRTUAL SOURCE - An apparatus for calculating driving coefficients for loudspeakers of a loudspeaker arrangement for an audio signal associated with a virtual source is described. | 09-20-2012 |
20120269368 | LOUDSPEAKER ARRAY SYSTEM - The invention is a multi-channel loudspeaker system that provides a compact loudspeaker configuration and filter design methodology that operates in the digital signal processing domain. Further, the loudspeaker system can be designed as a multi-way loudspeaker system comprised of a symmetric arrangement of loudspeaker drivers in a two-dimensional plane and can achieve high-quality sound, constant directivity over a large area in both the vertical and horizontal planes and can be used in connection with stereo loudspeaker systems, multi-channel home entertainment systems and public address systems. | 10-25-2012 |
20130279723 | ARRAY LOUDSPEAKER SYSTEM - A sound reproduction system for producing sound and 3D sound at the listener position by directing beams from an array loudspeaker using differential apodisation. Optionally, cross-talk cancellation is applied to beams directed to the listener's left and right ears. | 10-24-2013 |
20130287234 | Flat Ceiling Mounted Loudspeaker - A ceiling speaker mountable in a ceiling tile for mounting in a suspended ceiling of a room, includes a central woofer, and at least four surrounding pivoting tweeters that are independently adjustable so as to provide broad flat coverage throughout the room. A crossover network directs low frequency signals to the woofer and high frequency signals to the tweeters and an optional stereo separator circuit directs left and right signals to different pairs of the tweeters. A method for adjusting sound dispersion produced by the ceiling speaker is also disclosed. | 10-31-2013 |
