摘要： Spherical sound source comprising two coaxial loudspeakers and two mid-high frequency compression drivers. Low frequencies are radiated by the two low-frequency sections of the coaxial loudspeakers. Mid-frequencies 500 Hz-2000 Hz are radiated by the two mid-high frequency compression drivers. High-frequencies 2 kHz-10 kHz are radiated in the horizontal plane by the same mid-high frequency arrangement together with two compression drivers of the coaxial loudspeakers in each vertical direction. Identical drivers form three pairs. One driver from each pair is enclosed in one of two symmetrically opposite half-embodiments, spaced at predetermined distance to create a common radially expanding horn for the two mid-high frequency compression drivers. All loudspeakers share the same vertical axis of rotational symmetry. The two half-embodiments might be used as separate standalone spherically radiating sources when installed on hard surface. The invention is appropriate for sine-swept acoustic measurements and sound isolation measurements in high sound transmission class buildings.

摘要： An annular diaphragm compression driver for electro-acoustic conversion has an annular diaphragm, which bears a moving coil, and a compression driver housing with a closed housing base. Opposite the housing base is a sound wave routing element having a sound discharge channel. The compression driver also has an annular magnet system unit, which has an annular magnet gap (M) and a compression chamber, adjoining the magnet gap (M), for the annular diaphragm. The open exit end of the sound discharge channel is in slot form and its entry start is annular. The sound path between the compression chamber and the entry start contains an annular collecting space. The collecting space and the sound discharge channel contain a central sound guidance body having a portion which merges to match the slot-like exit end. The sound discharge channel is formed between the sound guidance body and the sound wave routing element.

摘要： Radial input waveguide is provided having three consecutive sound wave propagation passageways, virtually divided by two folding regions along its extension from radial input up to substantially rectangular output, each one forming a different type of waves and all three channels shaped between an internal body and a shell housing enclosing it at a distance. The radially expanding initial air channel forms a cylindrical wave front between two input walls. A relatively wide region with parallel walls is available for wave folding at adaptably changeable diameters in this region with a small distance between the folded walls. All individual partial wave fronts on the periphery of the first folding region are traveling along substantially equal, accumulated from the last two air channels, path lengths, to the waveguide output, forming there a common isophase and planar wave front. The middle passageway contains all the physical dimensions necessary to control the waveguide performance, the most important being the height H and the width D, whose ratio controls the wave front output curvature.

摘要： Single magnet coaxial loudspeaker having two air gaps on both sides of its faces, front gap of larger diameter for low frequency voice-coil and the opposite gap accommodating compression driver voice-coil. Front voice-coil drives low frequency membrane and rear voice-coil drives high frequency diaphragm, radiating sound waves through a phasing plug to the horn input through an opening into the magnetic structure, whereas the membrane acts as horn flair. Common region geometry around bottom pole of the magnetic structure controls flux line proportions between the two gaps. The five embodiments use series or parallel, inner or outer magnetomotive flux division. These are suitable for much simpler, more reliable and better balanced coaxial loudspeakers for professional and high-end markets.
摘要翻译：单磁同轴扬声器在其两侧具有两个空气间隙，用于低频音圈的较大直径的前间隙和容纳压缩驱动器音圈的相对间隙。前置音圈驱动低频隔膜和后音圈驱动高频隔膜，通过相位插头将声波通过开口进入磁性结构，将喇叭辐射到喇叭输入端，而隔膜则作为喇叭天赋。磁性结构底极周围的公共区域几何控制两个间隙之间的通量线比例。五个实施例使用串联或并联的内部或外部磁通通量分割。这些适用于专业和高端市场的更简单，更可靠和更均衡的同轴扬声器。
