At least one of the present exemplary embodiments and methods introduces a unique Audio Collection System comprised of self-contained Audio Collection Devices (ACDs), Audio Distribution Devices (ADDs), and Audio Control Analysis (ACA) components/functions. The system may be used to gather audio signals from environments in ways that are not presently available with the intention being to gather audio, analyze, and learn what may be understood about a given environment or situation. One exemplary feature of this system is that it introduces a set of standardized modular components that can be scaled from a small configuration to larger systems. For example, systems that may manage large numbers of audio input streams, broadcast audio streams, modify audio streams, combine and track sounds, and present sound as immersive experience. Additional features will provide other various controls and statistical capabilities, as described herewith.

The present application relates to the technical field of audio processing, and provides a method and a device for playing a smart speaker and a smart speaker. The method includes: controlling each speaker to output audio signals at a corresponding initial broadcast frequency, initial broadcast amplitude and initial broadcast phase when an azimuth angle of a user is not obtained; calculating an actual broadcast amplitude and an actual broadcast phase of each speaker through a sound energy focusing algorithm, the azimuth angle of the user, a broadcast angle of each speaker and the initial broadcast frequency of each speaker when the azimuth angle of the user is obtained; and controlling each speaker to output audio signals according to the corresponding initial broadcast frequency, the actual broadcast amplitude and the actual broadcast phase.

A vehicle speed detecting unit detects a vehicle speed. A threshold changing unit changes a threshold in accordance with the vehicle speed detected by the vehicle speed detecting unit. A gain calculating unit calculates a gain value of an input sound inputted to a microphone. A sound control unit mutes the input sound when the gain value of the input sound is equal, to or greater than the threshold changed by the threshold changing unit, the gain value being calculated by the gain calculating unit.

An audio system and method for generating improved augmented hearing effects in real-time. The system includes a wearable audio device arranged to obtain audio that includes a voice signal associated with a user and an environmental signal associated with other audio picked up by the wearable audio device that does not includes the user's voice. In some implementations, at least one processor of the wearable audio device is configured to isolate the voice signal from the environmental signal such that augmented hearing effects can be applied to the voice signal and/or the environmental signal, independently. In some implementations, augmented hearing effects are designated by a signal augmentation profile generated or stored in the wearable audio device such that the total time between receipt of the audio signal and the modifications and/or transformations to the respective audio signals does not exceed 100 ms.

An electronic device includes a housing; a printed circuit board; a microphone substrate; a microphone; a flash; a cover, the cover having an opening at least partially aligned with the flash; a flash window facing the cover, the flash window including a first part at least partially accommodated in the opening and at least partially aligned with the flash in the first direction, and a second part extended from the first part and between the cover and the microphone substrate; and an audio input path configured to propagate a sound wave to the microphone, wherein the audio input path may include a space provided between the flash window and the cover, a gap provided between the first part and an inner wall of the opening and fluidly connected to the space, and a microphone hole in the second part and fluidly connected to the microphone and the space.

A sound capture system can include a sound capture device configured for placement within a sound-generating device. The sound capture system can include a suspension system configured to suspend the sound capture device within the sound-generating device. The suspension system acoustically decouples the sound capture device from the sound-generating device. The sound capture device includes a plurality of transducers configured to generate a plurality of audio signals concurrently from sound generated by the sound-generating device. In another aspect, the sound capture system includes a signal processing circuit.

The acoustic attenuator also serves as a protective microphone enclosure that reduces exposure to debris as well as environmental humidity 5 and harmful gases.
