    摘要： Provided is an acoustic apparatus capable of causing a sensation that a sound is produced in a larger space than reality, without requiring an excessive cost and time-consuming installation. The sound collected by a microphone is converted to an electrical signal, and a reflected sound component is extracted by a signal processing portion. The reflected sound component thus extracted is amplified by an amplifier, and the reflected sound component thus amplified vibrates transducers attached to a back-side board surface of each acoustic structure, whereby reflected sound is emitted from all faces including front-side board surface and the back-side board surface. A player can thus naturally perceive as if the space where he stays is expanded.

    摘要： An electronic circuit for adding the effects of reverberation to a high impedance signal produced from an external audio source such as a guitar pickup or a high impedance microphone. The electronic circuit comprises a reverberation effects circuit having pre-amplifier/driver and recovery amplifier sections and a spring reverberation device coupled thereinbetween and a reverberation effects bypass at the circuit's input, prior to switchably passing the audio signal into an input of the pre-amplifier/driver section which comprises a low impedance, high current output for input into the spring reverberation device having an output for passing a low impedance signal to the recovery amplifier section, which suitably serves in increasing the impedance of the signal to a predetermined level acceptable for input into an external sound device such as an amplifier having channel inputs and audio control capabilities, and a power supply circuit having means for switching between a dc volt source and an ac volt source and supplying ±9 volts to integrated circuits (ICs) included in the pre-amplifier/driver and recovery amplifier sections of the reverberation effects circuit.

    摘要： An improved artificial reverberation system utilizing a unitary electro-acousto-electrical transducer of the electro-dynamic type in combination with means for eliminating the driving signal from the delayed output signal, such means including out-of-phase-signal cancellation circuits or time multiplexing circuits coupled to or integral with the unitary transducer achieves a high order of discrimination between driving and reflected signals in the system, thus permitting the use of a single transducer for both injecting signals and extracting reverberation signals.

    摘要： A reverberation system which employs low cost, spring reverberators and obtains a frequency response to beyond 9kHz. The high frequency components of an input signal are frequency shifted, to a lower range, applied to a reverberator, and then frequency shifted to their original range. This signal is then summed with the output of a second reverberator which receives the lower frequency components of the input signal.

    摘要： A choral effect is produced by operating a sound source element to produce sound traveling in a sound chamber, operating a sound detector element to detect sound traveling in the chamber, and, effecting movement of at least one of the elements so as to vary detected sound frequency and quality. A panel element may also (or alternatively) be moved to vary detected sound frequency and quality.

    摘要： The clamp is mounted within a reverberation unit so as to hold reverberation springs in place during transportation. The clamp is actuated by pushing an actuator into the unit so as to deflect a leaf spring and bring a channel-shaped holder thereon into restraining position about the reverberation springs. Movement of the actuator out of the unit allows the leaf spring to flatten and the holder to be moved away from the reverberation springs.
