  • Patent number: 12275637
    Abstract: Nano-electromechanical systems (NEMS) sensor devices that utilize thin electrically conductive membranes, which can be, for example, graphene membranes. The NEMS devices can have a trough shape (such as a serpentine shape arrangement) of the electrically conductive membrane. The thin, electrically conductive membrane has membrane-structures disposed upon it in an array of cavities. These membrane structures are between the thin, electrically conductive membrane and the main membrane trace. Such an arrangement increases the sensitivity of the NEMS sensor device. The electrically conductive membrane can be controllably wicked down on the edge of the oxide cavity to increase the sensitivity of the NEMS sensor device. Such NEMS sensor devices include NEMS sensor devices that are well suited to applications that measure magnetic fields that, operate below 10 kHz, such as brain-computer interfaces.

  • Patent number: 11595751
    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: 11575991
    Abstract: An improved loudspeaker system that produces an improved audio quality for stereophonic sound, which can be described as 3D audio. In one embodiment, the improved loudspeaker utilizes at least three stacks of electrostatic transducer cards, with one of the stacks located between the other two stacks. While there is generally some crossover between the frequencies of the stacks of electrostatic transducers, the middle stack will be directed to the lower frequency ranges and the other two stacks will be directed to the higher frequency ranges. Each of the three card stacks will utilize multi-track audio recordings, such as two-track audio recordings, which are modified for each of the three card stacks. In an alternative embodiment, the improved loudspeaker can utilize a conventional voice-coil driver in lieu of the middle stack of electrostatic transducer cards.

  • Patent number: 11425506
    Abstract: An improved compact electroacoustic transducer and loudspeaker system. The electroacoustic transducer (or array of electroacoustic transducers) can generate a desired sound by the use of pressurized airflow. The electroacoustic transducer does not have frames (unlike prior electroacoustic transducers) and an electrically conductive membrane is now supported by a pair of non-conductive vent members.

  • Patent number: 10791401
    Abstract: An improved loudspeaker that has a plurality of stacks of cards having electrostatic transducers, in which one stack of cards has a different width as another stack of cards in the plurality of stacks. At frequencies above 200 Hz, and at the same drive voltage and current, the stack of lesser width produced significantly greater microphone voltage as compared to the stack of greater width cards. By combining the plurality of stacks of cards with different widths, this provides for the elimination of conventional cone drivers, and provides for improved sound both above and below 200 Hz using only electrostatic transducers. It also assists in maintaining a null sound plane that is beneficial for voice recognition.
