International Classification:

H05K 3/46

US Classification:

216 17

Abstract:

The present invention relates to graphene windows and methods for making same. One method comprises selecting a high purity metal foil, growing a layer of graphene on a first face of the metal foil, patterning the second face of the graphene-modified foil with a polymer, wherein the second face of the graphene-modified foil has an exposed region and etching the second face of the graphene-modified foil in the exposed region until exposing the first layer of graphene.

International Classification:

H04R 1/02
H04R 1/24
H04R 1/28
H04R 11/02

Abstract:

Electroacoustic drivers that can be utilized in loudspeaker systems that utilize bidirectional force electromagnet transducers or piezoelectric transducers. The electroacoustic drivers can include motion amplifiers such as lever arms. The electroacoustic drivers can be used at all audio frequencies including frequencies below 500 Hz.

International Classification:

H04R 19/02
G06F 3/16

H04R 19/04

H04R 7/04

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.

Assignee:

Clean Energy Labs, LLC - Austin TX

International Classification:

H04R 19/02
H04R 31/00
H04R 1/22

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 can have vented stators and can have a strong-weak ultra-thin loudspeaker transducer pair design.

International Classification:

H04R 19/02
H04R 7/04
H04R 1/28
H04R 1/02

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.

International Classification:

H04R 1/02

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.
