Abstract
A reverberation device includes a mechanical delay device in the form of a coil from an elongate strip of metal in an example embodiment. The length can be greater than an order of magnitude greater than the height dimension. The height dimension is greater than the thickness dimension. The mechanical delay device can be fed an audio signal from an electro-mechanical transducer and output mechanical vibrations to a mechanical-electrical transducer. The coil can be folded at the center of the coil so that the input and output are both on the outside of the coil. The input path is interleaved with the output path for the signal in the coil.
Claims19
A reverberation device, comprising:
- an input for an audio signal;
- a mechanical delay coil to receive the audio signal to produce a delayed audio signal, the coil including an elongate body having a length dimension that is wound around itself with a height less than the length and a thickness less than the height;
- and
- an output to output the audio signal and the delayed audio signal to produce an audio output signal.
A reverberation device, comprising:
- an input for an audio signal;
- a mechanical delay coil to receive the audio signal to produce a delayed audio signal, the coil including an elongate body having an input end, an output end, and a length between the input end and the output, the length of the body is wound around itself, the elongate body having a height less than the length and a thickness less than the height, the input end being connected to the input;
- and
- an output to output the audio signal and the delayed audio signal to produce an audio output signal, the output being connected to the output end.
