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

Publication number: 20230239625Abstract: Voice coil actuators and loudspeakers containing same. The voice coil actuators include moving voice coil assemblies that have multiple segments. Each segment of a moving voice coil assembly is separately controlled by an amplifier, one channel of an amplifier, and combinations thereof utilized in combination with a position sensor that senses the position of the moving voice coil assembly. By this arrangement, the voice coil actuators produce a linear force per unit current throughout the range of motion while obtaining the benefits and advantages associated with both over-hung and under-hung voice coil actuator designs.Type: ApplicationFiled: June 4, 2021Publication date: July 27, 2023Applicant: CLEAN ENERGY LABS, LLCInventors: Joseph F.

Patent number: 11595751Abstract: 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.Type: GrantFiled: May 2, 2019Date of Patent: February 28, 2023Assignee: Clean Energy Labs, LLCInventors: Joseph F.

Patent number: 11575991Abstract: 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.Type: GrantFiled: October 24, 2019Date of Patent: February 7, 2023Assignee: Clean Energy Labs, LLCInventors: David A.

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. Pinkerton, David A. Badger, William Neil Everett, William Martin Lackowski
