Abstract: A two-dimensional array of a plurality of transducers comprising a first plurality of like sub-arrays (11, 11a, 11b) of transducers (10) in a circularly symmetric arrangement around a common centre (C), where the transducers in each sub-array of the first plurality have individual distances from the common centre that form a progressive series of distances with a first lower limit and a first upper limit. Each sub-array in the first plurality of sub-arrays comprises at least three transducers arranged on a first straight line (12), and the first straight line is offset laterally a first distance (d) from the common centre. The number of sub-arrays is odd, and the sub-arrays may be separate units that can be selectively assembled to form the two-dimensional array and selectively disassembled.

Abstract: A Bessel Array loudspeaker in which identical transducers are fed full amplitude signals. The half amplitude output at some Bessel positions can be achieved by angling those transducers to the side or up/down. The half amplitude transducers can be coupled to separate cabinets which can be rotated left/right with respect to the full amplitude transducers' cabinet, and the rotation can automatically reconfigure the wiring of the half amplitude transducers. The half amplitude output can alternatively be achieved by driving only half of the voice coil windings of the half amplitude transducers. The other half of their voice coil windings can optionally be driven via a low pass filter, to achieve an Improved Bessel with increased bass output and sensitivity.

Abstract: A dipole loudspeaker in which the oppositely oriented transducers each is a Bessel Array. Optionally, Improved or Super Bessel Arrays are used, and their half-amplitude end position transducers may be shared and aimed in a perpendicular—typically vertical—orientation. The Bessel Dipole is especially useful as a surround channel loudspeaker; for the same effective radiating area and/or sound production, the Bessel Dipole has a narrower cabinet than a conventional two-transducer dipole loudspeaker.

Abstract: An improved Bessel array of electromagnetic transducers, in which the Bessel coefficients (phase and/or magnitude) are applied only in the useful high frequency range, where off-axis interference patterns between the outputs of respective transducers cause undesirable acoustic results. One improvement is in using an all-pass filter or the like in lieu of an inverter in the inverting Bessel coefficient path, to provide an in-phase signal in low frequencies and an opposite-phase signal in high frequencies. This achieves the improved off-axis result of a conventional Bessel array, with improved low-frequency maximum sound pressure and efficiency. Another improvement is in using a frequency-dependent voltage divider, such as a shelf circuit, in the half-strength Bessel coefficient paths, to provide full-strength signals in low frequencies and half-strength signals in high frequencies. This achieves even more improved low-frequency maximum sound pressure. Yet another improvement is in using a high-pass filter in front of the inverting Bessel coefficient path, to provide a zero signal in low frequencies and an opposite phase signal in high frequencies.
Abstract translation: 一种改进的贝塞尔电磁换能器阵列，其中贝塞尔系数（相位和/或幅度）仅应用于有用的高频范围，其中各个换能器的输出之间的离轴干涉图形导致不期望的声学结果。 一个改进是在反相贝塞尔系数路径中使用全通滤波器等来代替逆变器，以提供低频的同相信号和高频的相位相位信号。 这实现了常规贝塞尔阵列的改进的离轴结果，具有改进的低频最大声压和效率。 另一个改进是在半强度贝塞尔系数路径中使用频率依赖的分压器，例如搁架电路，以提供高频下的全强度信号和高频率的半强度信号。 这实现了更加改进的低频最大声压。 另一个改进是在反相贝塞尔系数路径前面使用高通滤波器，在低频中提供零信号和在高频率下提供相反的相位信号。
