Abstract: A diaphragm for use in an audio transducer (e.g., a coaxial loudspeaker) includes a higher frequency transducer and a lower frequency transducer. The diaphragm is a component of the lower frequency transducer and is arranged coaxially with the higher frequency transducer. The diaphragm includes a first surface and an opposing second surface. The first surface has a profile shaped to define a horn for output from the higher frequency transducer and the geometry of the first surface is independent of the geometry of the second surface.

Abstract: Systems and methods that facilitate motion formalism utilizing quantum computing, to compute matrix operators in terms of commutators between qubit operators and measurements on the quantum hardware, wherein the commutators are computed utilizing symbolic calculus. Embodiments reduce computational cost of generalized eigenvalue synthesis relying on symbolic calculus and parallelization. Embodiments disclosed herein can also develop estimators of excited-states properties, considering constants of motion (e.g. spin) and non-constants of motions (e.g. dipoles, density matrices).

Abstract: A coaxial loudspeaker includes a cone of a woofer; a waveguide of a tweeter, located at a front end towards the outside/large profile of the cone; and a first cavity. The first cavity includes a resonator and a cavity formed in the cone, and the resonator communicates with the cavity at the large profile of the cone. A side opposite to a position where the resonator communicates with the cavity is constructed as an orifice plate. The orifice plate is adjacent to the resonator and an orifice portion of the orifice plate communicates with the resonator.
