Abstract
At least two coil spring rotational mode reverberation lines having transducers at two remote ends thereof are coupled in cascade circuit by means of intermediate long wire transverse mode line structure. Thus, two (or more) coils may be located side by side with a long thin wire coupling opposite ends of the coils, thereby considerably reducing packaging size of long time delay reverberation lines, and producing coupling means that is less susceptible to physical shock. The wire comprises universal type coupling means for coupling together coils of different characteristics.
Claims10
An artificial reverberation line comprising in combination, at least two coil springs coupled into said line in cascade from a first spring to a terminal spring, transducer means for introducing acoustic energy into the first spring in a rotational mode, transducer means for deriving acoustic energy in the rotational mode from the terminal spring, and transverse wave motion transmission means coupled between a selected two of said springs in said line with first coupling means to convert said rotational mode energy from one spring and transmit it in the transverse wave motion mode and second coupling means to transfer the transverse wave motion into the rotational mode into said other spring.
