Publication number: 20230345180Abstract: 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.Type: ApplicationFiled: September 18, 2020Publication date: October 26, 2023Applicant: CLEAN ENERGY LABS, LLCInventors: Joseph F. Pinkerton, David A. Badger, James A. Andrews, William Martin Lackowski, William Neil Everett

Patent number: 10791401Abstract: 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.Type: GrantFiled: July 12, 2019Date of Patent: September 29, 2020Assignee: Clean Energy Labs, LLCInventors: Joseph F.

Patent number: 10694009Abstract: A communications system and method of use thereof in which communication system includes a substrate and an array of pumps of mounted on the substrate. The array of pumps are operable for operating at a first frequency to produce sound waves at a second frequency. The first frequency is higher than the second frequency. IN some embodiments, the pumps in the array of pumps can include a first cavity having a first inlet and a first outlet, a first plurality of electrically conductive traces located within the first cavity, and a continuous sheet of electrically conductive material spaced apart from and in close proximity to the first plurality of electrically conductive traces. 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.Type: GrantFiled: March 30, 2017Date of Patent: June 23, 2020Assignee: Clean Energy Labs, LLCInventors: David A.
