Publication number: 20230308801Abstract: A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.Type: ApplicationFiled: June 1, 2023Publication date: September 28, 2023Inventors: Brian Lloyd SCHMIDT, David Thomas ROACH, Michael Z.

Patent number: 8406445Abstract: A loudspeaker system has a high frequency channel for driving a horn loaded high frequency transducer, and a low frequency channel for driving a low frequency transducer. A signal processing circuit is provided which has at least one first order and at least one second order cross-over circuit portion in the high channel and at least one first order and at least one second order cross-over circuit portion in the low frequency channel. These cross-over portions produce a cross-over frequency range for the loudspeaker system that is below the cut-off frequency of the horn. The signal processing circuit, including its cross-over circuit portions and in conjunction with the design of the expansion walls of the horn, extends vertical beamwidth control of the acoustic output of the loudspeaker system at the loudspeaker system's lower frequency range.Type: GrantFiled: October 1, 2010Date of Patent: March 26, 2013Assignee: Meyer Sound Laboratories, IncorporatedInventors: Jon M. Arneson, Paul Kohut, John D. Meyer, Pablo Espinosa, Richard D. Herr

Patent number: 8238588Abstract: A loudspeaker system has a plurality of relatively small transducer elements configured in a closely spaced transducer array such that their acoustic outputs combine to produce a focused beam of sound in front of the array that is substantially uniform about the beams radiation axis. The transducer array lies in a plane and has a perimeter that approximates a circle, and will have fill-factor with respect to a circle circumscribing the array of at least approximately 70%. In one variation of the loudspeaker system, the transducer array is constructed in smaller transducer array modules that are operatively fitted together to produce a larger array.Type: GrantFiled: January 28, 2009Date of Patent: August 7, 2012Assignee: Meyer Sound Laboratories, IncorporatedInventors: John D. Meyer, Perrin Meyer, Roger Schwenke, Alejandro Antonio Garcia Rubio, Paul Joseph Kohut, Richard D. Herr, Jon M. Arneson, Peter C. Soper

Patent number: 6668969Abstract: A manifold for a horn loudspeaker has an input end having at least one input port for receiving acoustic power from at least one acoustic driver, and an output end for delivering acoustic power to the throat end of the horn. The output end of the manifold has at least two and suitably multiple output ports. An acoustic power waveguide is provided for each output port and connects each of the output ports to the input port of the manifold. Acoustic power received by the input port is divided between the acoustic waveguides such that it is delivered to the aligned output ports to simulate a line array of acoustic power sources.Type: GrantFiled: January 11, 2002Date of Patent: December 30, 2003Assignee: Meyer Sound Laboratories, IncorporatedInventors: John D. Meyer, Perrin Meyer, Richard D. Herr
