Abstract
Disclosed are systems and methods utilize networked speaker arrays and audio waveform shaping using interferometric feedback of sound transmitted by the speaker arrays. In further aspects, the systems and method employ an intelligently controlled acoustic device that can focus sound at specific locations and record the acoustic environment/reflected sound to self-calibrate for improved performance. Moreover, the device is modular and scalable with the ability to network distributed speakers to enhance the audio performance.
Claims10
A system for providing coherent acoustic energy, the system comprising:
- a distributed speaker array system including a plurality of speakers communicatively coupled to at least one controller and where at least one of the plurality of speakers are configured to be mobile;
- and
- at least one interferometric device configured for measuring at least acoustic sound energy from the distributed speaker array system that causes vibration and/or is reflected off one or more objects;
- wherein the at least one controller is configured to receive the measured acoustic sound energy from the at least one interferometric device and control characteristics of the acoustic sound energy being transmitted from one or more of the plurality of speaker based on the measured acoustic sound energy from the interferometric device.
A method comprising:
- directing acoustic energy toward one or more objects with a distributed acoustic array system
- recording, detecting, and/or measuring acoustic sound energy emanating from a location of the at least one object with an interferometer;
- determining one or more adjustment parameters for sound output one or more sound output devices in the distributed acoustic array based on the recorded, detected and/or measure acoustic sound energy;
- and
- communicating the determined one or more adjustment parameters to the one or more sound output devices via a network communicatively coupling the one or more sound output devices.
