摘要： The apparatus of the invention comprises a loudspeaker, preferably, having a nearly flat diaphragm, and a plurality of microphones disposed in confronting relationship to the diaphragm of the loudspeaker at different positions in a sound radiation plane of the diaphragm, so that the microphones can individually pick up sounds radiating from different portions of the diaphragm where vibrational modes are expected to be different from one another. Further to finish a tremolo effect to the sounds finally produced, the sound waves from the loudspeaker to the microphones are periodically interrupted. According to one example of the invention, such periodical sound interruption may be caused by rotating the loudspeaker itself, and according to another example thereof, there may be employed a sound interrupting member having therein sound passages for selectively and locally passing the sound waves emitted from the different portions of the loudspeaker to the respective microphones, such sound interrupting member being disposed rotatably between the loudspeaker and the microphones.

摘要： A rotary loudspeaker system comprising, in combination, a rotatable loudspeaker and a reflector plate for reflecting sound radiated from the loudspeaker toward a listener. The reflector plate is located near the loudspeaker in such position that it does not interfere with the rotating movement of the loudspeaker and at such angle that it reflects the sound radiated from the loudspeaker toward the listener. The reflector plate is formed by a part of a cabinet in which the loudspeaker is housed. The angle of the reflector plate may be made adjustable. The reflector plate may be closed to form a completely enclosed cabinet.
摘要翻译：一种旋转扬声器系统，其组合包括可旋转的扬声器和用于将从扬声器辐射的声音反射到收听者的反射板。反射板位于扬声器附近，使得它不会干扰扬声器的旋转运动，并且以这样的角度将扬声器辐射的声音反射到收听者。反射板由容纳扬声器的机柜的一部分形成。反射板的角度可以调节。反射板可以关闭以形成完全封闭的机柜。

摘要： A reverberation unit derives an instrument signal through an electrical phase shift vibrato device that imposes a maximum frequency deviation that is substantially constant for all notes in the musical range. The inherent comb-shaped frequency response of the reverberation device relatively attenuates certain notes. A second channel that includes acoustic pulsato apparatus derives instrument signal independently of the electrical vibrato device and provides with the first channel a distinct component to the total pulsato effect by virtue of the independency. Cessation of primary instrument signal provides a nonpulsato decaying reverberation the frequency response characteristic of which is substantially uniform due to the constant maximum frequency deviation pattern imposed prior to the cessation of signal.
