  • Patent number: 11064285
    Abstract: A tunable contact microphone is fabricated from nanometer size piezoelectric materials. The piezoelectric nanostructures are deposited on a flexible substrate or tunable resonant backplane. The backplane can be designed to vibrate at fundamental harmonic or sub-harmonic frequencies from 10 Hz to 20 KHz, corresponding to vibration frequencies of the human cranium. The backplane can be attached to a band or other material that will facilitate the attachment to the forehead, behind the ear or throat, with a preferred location being the forehead. When a person speaks, the backplane vibrates causing the nanostructures to generate electricity. The electrical signals are sent to an impedance matching preamplifier. The signal can then be sent to a communications system or fed into the microphone input of a communication system.

  • Patent number: 11019414
    Abstract: A wearable microphone array apparatus and system used as a directional audio system and as an assisted listening device. The present invention advances hearing aids and assisted listening devices to allow construction of a highly directional audio array that is wearable, natural sounding, and convenient to direct, as well as to provide directional cues to users who have partial or total loss of hearing in one or both ears. The advantages of the invention include simultaneously providing high gain, high directivity, high side lobe attenuation, and consistent beam width; providing significant beam forming at lower frequencies where substantial noises are present, particularly in noisy, reverberant environments; and allowing construction of a cost effective body-worn or body-carried directional audio device.

  • Patent number: 11009954
    Abstract: One embodiment of the present disclosure sets forth a technique for delivering audio output and generates haptic sensations on or proximate to objects in an environment via which a user can perceive haptic sensations. The device includes transducer arrays that operate in various modalities, including generating audio output, generating haptic output, and sensing objects in the environment. When generating audio output, the transducer arrays produce ultrasonic waves that demodulate to produce audio output. When generating haptic output, the transducer arrays output directional haptic output to various locations to the environment using constructive and/or destructive interference. When sensing objects in the environment, the transducer arrays generate pings and detect ping echoes reflected off of objects in the environment.

  • Patent number: 11012786
    Abstract: A pre-distorted electrical excitation signal is generated for an acoustic transducer having an armature and a non-linear transfer characteristic by applying an electrical input signal (x) representative of a desired acoustic output to a computable non-linear function that is a function of the electrical input signal (x). When applied to an input of the transducer, the pre-distorted electrical excitation signal results in an improved acoustic output signal.

  • Patent number: 10972831
    Abstract: A speaker system broadly comprises a plurality of speaker assemblies each including a speaker housing, an input circuit, a low range speaker, and a higher-range speaker. The input circuit receives audio signals from a sound system or other controller and actively or passively sends the audio signals to the speakers. The low-range speaker is positioned in the upper section and the higher-range speaker is positioned in the lower section. Each speaker assembly is configured to be spaced from the other speaker assemblies within a listening area with each speaker assembly generating low frequency soundwaves and higher-frequency soundwaves. This reduces or eliminates out-of-phase crossover frequency wave cancellation effects within the listening area. The speaker housings are compact while allowing the low-range speaker and higher-range speaker to effectively produce and project desired soundwaves from the suspended speaker housing into the listening area.
