  • Patent number: 11598962
    Abstract: A plurality of modal parameters is estimated for a set of discrete locations within a local area using a set of room impulse responses for the set of discrete locations. The local area includes an audio system. A plurality of acoustic model parameters is generated by fitting the plurality of modal parameters to an acoustic model that accounts for a physical geometry of the local area. The plurality of acoustic model parameters and an indication about the acoustic model are stored for later use by the audio system. The audio system estimates the set of acoustic parameters using the plurality of acoustic model parameters and the indication about the acoustic model, and presents audio content using the set of acoustic parameters.

    Abstract: Dipole audio speakers, and more particularly, voice controlled dipole audio speakers having at least one microphone located substantially along the null sound plane of the dipole audio speaker. An improved loudspeaker system that produces an improved audio quality for stereophonic sound. The improved loudspeaker utilizes conventional electro-dynamic drivers in a sealed chamber that produce sound primarily in the 20-300 Hz band coupled with electrostatic card stack drivers placed outside the sealed chamber that cover the remaining 98% of the audio frequency spectrum (300 Hz to 20 kHz). The improved loudspeaker system can also include multiple card stack drivers that are placed at angles with respect to each other to maximize audio fidelity.

  • Patent number: 11570558
    Abstract: An illustrative stereo rendering system obtains a contradirectional audio input signal generated by a microphone assembly having a plurality of microphone elements. The contradirectional audio input signal implements a contradirectional polar pattern oriented with respect to a listener. The system also obtains an array of multidirectional audio input signals generated by the microphone assembly. The array of multidirectional audio input signals implements different unidirectional polar patterns that are collectively omnidirectional in a horizontal plane. The system generates a weighted audio input signal by mixing the array of multidirectional audio input signals in accordance with respective weight values assigned to each multidirectional audio input signal. The system then generates, based on the contradirectional audio input signal and the weighted audio input signal, a stereo audio output signal for presentation to the listener. Corresponding systems and methods are also disclosed.

  • Patent number: 11526645
    Abstract: Method and electronic circuit for determining a scaling factor k for a driving force function of a model of an electrodynamic acoustic transducer having at least two voice coils. Input signal fed into the transducer and it's model cause electromotive forces. A shift for the driving force function is determined on the base of the ratios between the real electromotive forces and the modeled electromotive forces. Finally, the scaling factor k is determined on the basis of a deviation between the real electromotive forces and the modeled electromotive forces at time points where the real electromotive forces and the modeled electromotive forces each are equal. The invention moreover relates to an electronic circuit for performing the above steps, and to a transducer system with the electronic circuit and a connected transducer.

  • Patent number: 11425477
    Abstract: Systems, methods, and apparatus are provided for recording high output power levels of sound at low sound pressure levels. For example, an apparatus comprises an enclosure, a speaker disposed within the enclosure, a microphone disposed within the enclosure, and an evacuation port. The evacuation port is configured to connect to a system that reduces a pressure level within the enclosure to a level that is less than an ambient air pressure level outside the enclosure. The enclosure is sealed or otherwise configured to provide a sealed enclosure, to maintain the reduced air pressure within the enclosure. The speaker can be driven by an amplifier at high output power levels to generate a distorted sound of an amplified electric musical instrument for recording purposes, while the reduced pressure level within the enclosure serves to attenuate the sound pressure level and perceived loudness which emanates from the speaker.

  • Patent number: 11418894
    Abstract: A media system and a method of using the media system to accommodate hearing loss of a user, are described. The method includes selecting a personal level-and-frequency dependent audio filter that corresponds to a hearing loss profile of the user. The personal level-and-frequency dependent audio filter can be one of several level-and-frequency-dependent audio filters having respective average gain levels and respective gain contours. An accommodative audio output signal can be generated by applying the personal level-and-frequency dependent audio filter to an audio input signal to enhance the audio input signal based on an input level and an input frequency of the audio input signal. The audio output signal can be played by an audio output device to deliver speech or music that the user perceives clearly, despite the hearing loss of the user. Other aspects are also described and claimed.

  • Patent number: 11418874
    Abstract: A first digital signal processor (DSP) associated with a first user outputs audio to the first user via first headphones, and captures speech from the first user via a first microphone. Similarly, a second DSP associated with a second user outputs audio to the second user via second headphones, and captures speech from the second user via a second microphone. The first DSP is coupled to the second DSP in order to allow the first and second users to share music and communicate with one another. The first user may speak into the first microphone, and the first and second DSPs may then interoperate to output that speech to the second user without substantially disrupting audio output to the second user. Each of the first and second users may also select between first and second audio sources that may be coupled to the first and second DSPs, respectively.

  • Patent number: 11335314
    Abstract: Adaptive filters output a cancellation sound from a speaker, a selector selects outputs of a plurality of auxiliary filters each corresponding to different positions, a subtractor subtracts the selected output from the output of the microphone and outputs the subtracted output to the adaptive filter as an error signal, and a position detection device detects a position of a head of a user. A transfer function estimated so that the error signal becomes 0 when noise is canceled at the corresponding position is preset in the auxiliary filter. When the auxiliary filter corresponding to the position close to the head of the user changes, the switching control unit stepwise increases the frequency with which the output of the auxiliary filter is selected by the selector to 100%.
