摘要： Means forming an air channel is connected between the output of a loudspeaker and the input of a microphone. The output of the microphone is amplified by means of an amplifier, the output of the amplifier being fed to the speaker, an acoustical feedback path thus being formed between the speaker and the microphone. A mouthpiece is connected in this acoustical path such that an operator can determine the frequency of the feedback signal by adjusting the size of his oral cavity, thus forming musical tones.

摘要： A sound capture device is affixed to an acoustic instrument to capture the natural sound output of the instrument. The captured sound signal is routed to an electronic sound augmentation system that is configured to augment the captured sound with spatial sound effects such as reverb, echo, delay, etc. The processed and augmented sound is then reproduced via a vibrating driver that has been affixed to the body of the acoustic instrument. This creates a situation where the body of the musical instrument, responding to a series of vibrations produced by the vibrating driver, acts as a speaker component, reproducing a rich augmented sound output that comprises the sum of the sound produced by the original sound production capabilities of the acoustical instrument plus the added augmented or enhanced sound effects.

摘要： A dipole microphone assembly for a nearfield sound source has a first microphone and a second microphone. The second microphone is out of phase with the first microphone so as to provide a dipole microphone assembly. Each of the microphones has a port, and a dipole spacing is defined as a distance from the center of the port of the first microphone to the center of the port of the second microphone. The dipole spacing is less than ¼ of a wavelength for the highest frequency of the sound of interest.

摘要： In an apparatus for assisting play of a wind instrument, an actuator is attached to the wind instrument for vibrating a portion of the wind instrument so as to assist play of the wind instrument. A microphone receives a vibration of a sound generated by the wind instrument and generates a vibration signal representing the vibration of the sound. A breath pressure sensor detects a pressure of a breath that is blown into the wind instrument during the play thereof, and generates a breath pressure signal corresponding to the detected pressure of the breath. A controller generates a control signal corresponding to the product of an inverse value of an envelope of the vibration signal and a value of the breath pressure signal. A variable gain amplifier amplifies the vibration signal with a variable gain which varies in response to the control signal so that an output signal of the variable gain amplifier is provided to enable the excitation part to vibrate the portion of the wind instrument.

摘要： An acoustical device is provided in the form of a stringed musical instrument having a hollow resonant body. A speaker is coupled to the resonant body so that the speaker generally overlays the strings of the musical instrument. A power supply is mounted to the instrument for powering the speaker. A sound processing device is provided for receiving at least one of a first sound signal that is generated from the strings of the musical instrument and a second sound signal. The sound processing device generates an output signal to the speaker from at least one of the first and second sound signals. The sound processor has at least one non-overall-volume sound effect generating function.
