  • Patent number: 12284507
    Abstract: Force transducers for use in electrostatic drivers, including electrostatic drivers that can be utilized in loudspeaker systems that utilize drivers having a magnetic negative spring (MNS) (such as reluctance assist drivers (RAD) and permanent magnet crown (PMC) drivers). The electroacoustic drivers having the force transducers can be used at all audio frequencies, including subwoofer frequencies.

  • Patent number: 12256207
    Abstract: Electroacoustic drivers that can be utilized in loudspeaker systems that utilize drivers having a magnetic negative spring (MNS) (such as reluctance assist drivers (RAD) and permanent magnet crown (PMC) drivers). The electroacoustic drivers can be used at all audio frequencies, including subwoofer frequencies. The magnetic negative springs of the electroacoustic drivers can cancel, or partially cancel, the large pressure forces on a sound panel (of an audio speaker) so that substantial subwoofer notes can be efficiently and cost effectively produced in small/portable speakers. The electroacoustic drivers can include a stabilizing/centering mechanism to overcome the destabilizing forces of a MNS that are too large for a voice coil alone to produce.

  • 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: 11134336
    Abstract: A case-baffle-stand system utilized with a dipole speaker, in which the case-baffle-stand system has a cover that, when opened, is a baffle to enhance the sound waves emitting from the speaker system and is also a stand to stabilize the speaker in its proper standing orientation, and when closed, protects the speaker.

  • Publication number: 20210058712
    Abstract: An improved loudspeaker that has a plurality of electrostatic transducers forming a card stack that is housed in a stack holder. The stack holder can support the loudspeaker perforated grill (or mesh), can secure the card stack to the speaker case, and can provide a watertight electrical connection to the sealed chamber of the loudspeaker (that contains the main circuit board for controlling the loudspeaker).

  • 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.
