  • Patent number: 10771915
    Abstract: The present invention relates to the technical field of a car stereo audio expanding method. The method performs delay processing on sound channel signals in a loudspeaker twice to counteract signals reflected by door glass, such that the sound field performs better. The sound field processing method of the present invention can enable the sound field of sounds heard by the driver to be centered and the diffusion of both sides to be symmetric. Also the sound field can be expanded to the outside of the vehicle, resolving the problem that the car audio, in a car environment, has a sound field weighted toward one side, has a narrow sound field width, and has poor hearing effects due to the confined sound field. The invention enables sound heard to be authentic rather than empty.

  • Patent number: 10377486
    Abstract: A drone speaker system is configured to deploy a fleet of drone speaker units. Each drone speaker unit includes a speaker configured to broadcast acoustic signals and a flight system configured to aerially transport a speaker. The drone speaker system initially generates a spatial map of a location where the drone speaker units are to be deployed. The drone speaker system then identifies suitable perching locations for the drone speaker units. Then, the drone speaker system deploys the fleet of drone speaker units to those perching locations to place one or more speakers. Once positioned in this manner, the speakers can generate a sound field. The drone speaker units may also reconfigure the speakers to achieve different sound fields having varying characteristics.

  • Patent number: 10262664
    Abstract: When combining digital data sets in the time domain into a combined digital data set a subset of samples of each digital data set is adjusted to enable unraveling the data when decoding. To enable correction during decoding of an error introduced by the adjustment, an error approximation is stored for each adjusted sample. A set of error approximations is created which is indexed allowing substantial reduction in size of the error approximations to be stored for the adjusted samples. Instead of creating a set of error approximations for each combined digital data set one set of error approximations is created based on the errors introduced when creating multiple combined digital data sets.

  • Patent number: 9036828
    Abstract: In a method for outputting music information in a vehicle by way of an audio system having loudspeakers in the front area and rear area of the vehicle, the behavior of the vehicle is determined by use of an acceleration sensor responding to longitudinal accelerations. The loudspeakers arranged in the direction of the respective acceleration are at least preferably activated.

  • Patent number: 9014392
    Abstract: Introduction of sounds outside a vehicle is automatically controlled according to a driving state of the vehicle. In a vehicle, a microphone device that collects sounds outside the vehicle and a speaker device that reproduces the collected sounds are installed. When a gear position for the vehicle is a reverse driving position, and until the vehicle reaches a predetermined speed for the first time after a key position in an ignition key switch is switched from an off position to an accessories position or an on position, the collected sounds are reproduced. The collected sounds are transmitted to a car navigation device or a car audio system via wires or wirelessly. When the sounds outside the vehicle are reproduced, sound reproduction in the car navigation device or the car audio system is stopped and the sounds outside the vehicle are reproduced at a set volume.

  • Patent number: 9014404
    Abstract: A multichannel audio system for radiating sound to a listening area that includes a plurality of listening spaces. The audio system includes directional audio devices, positioned in a first of the listening spaces, close to a head of a listener, for radiating first sound waves corresponding to components of one of the channels and nondirectional audio devices, positioned inside the listening area and outside the listening space, distant from the listening space, for radiating sound waves corresponding to components of a second of the channels.

  • Publication number: 20150055807
    Abstract: An apparatus and a method for driving loudspeakers of a sound system in a vehicle, the system having at least two loudspeakers of a basic system, and a plurality of loudspeakers of a focus system wherein each of the loudspeakers has a position in an environment. The apparatus includes a basic channel provider for providing basic system audio channels for driving the loudspeakers of the basic system and a focused source renderer for providing focus system audio channels to drive the loudspeakers of the focus system. The focused source renderer is configured to calculate a plurality of filter values for the loudspeakers of the focus system based on the positions of the loudspeakers of the focus system and based on a position of a focus point.

    Abstract: Entertainment systems are provided including directional sound speakers embedded in a headrest of a passenger seat, the headrest being associated with a media player of the entertainment system; and a directional sound controller associated with the directional sound speakers of the media player. The directional sound controller is configured to direct a sound beam associated with the media player at a defined target region such that the sound beam is only audible within the defined target region and experiences less than about 20 dB of leakage outside the target region during operation of the media player. In-flight entertainment systems and related methods are also provided.

  • Publication number: 20140355793
    Abstract: Signals in an automobile audio system having at least two near-field speakers located close to an intended position of a listener's head are adjusted such that in a first mode, audio signals are distributed to the near-field speakers according to a first filter that causes the listener to perceive a wide soundstage, and in a second mode, the audio signals are distributed to the near-field speakers according to a second filter that causes the listener to perceive a narrow soundstage. A user input of a variable value is received and, in response, distribution of the audio signals is transitioned from the first mode to the second mode, the extent of the transition being variable based on the value of the user input.

  • Patent number: 8903527
    Abstract: An acoustic apparatus and a method thereof in a mobile terminal are provided. More particularly, an apparatus and a method for establishing a multi-sound system that provides sounds of sense of reality by connecting with players existing in the neighborhood and reproducing channels of contents using a plurality of players when reproducing the contents including multi-sound channels are provided. The apparatus includes a control player, a server player, and a client player. The control player selects players that reproduce respective channels using information of the channels forming the multi-sound channel contents. The server player analyzes the contents to be reproduced by the players to provide the information regarding the channels to the control player. The client player reproduces the channels of the relevant contents under control of the control player.

  • Publication number: 20140348353
    Abstract: A system and method for acoustically reproducing at least two electrical audio signals and establishing at least two sound zones that are represented by individual patterns of reception sound signals includes processing the at least two electrical audio signals to provide processed electrical audio signals; converting the processed electrical audio signals into corresponding acoustic audio signals with at least two loudspeakers that are arranged at positions separate from each other; transferring each of the acoustic audio signals according to a transfer matrix from each of the loudspeakers to each of the sound zones where they contribute to the reception sound signals; and processing of the at least two electrical audio signals comprises inverse filtering according to a filter matrix. Inverse filtering is configured to compensate for the room transfer matrix so that each one of the reception sound signals corresponds to one of the electrical audio signals.
