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.

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.

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.

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).

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.

The first plurality of electrically conductive traces are operable for creating a first time-varying deflection in the electrically conductive material. The first time-varying deflection moves in the first cavity from the first inlet to the first outlet.

Abstract: An improved compact electroacoustic transducer and loudspeaker system. The electroacoustic transducer (or array of electroacoustic transducers) can generate the desired sound by the use of pressurized airflow. The electroacoustic transducer uses a shared stator with an array of vent support fingers and metal frame instead of two stators per electroacoustic transducer.

Abstract: This disclosure relates to loudspeakers that use one or more stacks of electrically actuated cards that pump air through vents to produce sound waves in response to an acoustic signal. Each stack can include several electrostatic actuator cards that are stacked on top of each other and collectively operate to pump air through a vent to produce a sound wave. Each card may include an electrically conductive membrane that is pushed/pulled between two electrically conductive stators. As the membrane is pushed and pulled along a first axis, air is pumped through vents in a direction orthogonal to the first axis. In one embodiment, stacks of cards can be arranged in series to increase sound pressure generated by the loud speaker. In another embodiment, a single stack of cards can be driven with relatively high electric field strength to increase the sound pressure generated by the loud speaker.
