Abstract
A microphone jammer includes a base and a signal generator mounted to the base. The signal generator is configured to generate an ultrasonic signal. The jammer also includes one or more transducers mounted to the base and configured to transmit the ultrasonic signal. The one or more transducers are mounted in a curved layout about the base.
Claims18
A microphone jammer comprising:
- a base;
- a signal generator mounted to the base and configured to generate a plurality of ultrasonic signals;
- one or more transducers mounted to the base and configured to transmit the plurality of ultrasonic signals, wherein the one or more transducers are mounted in a curved layout about the base;
- and
- a processor configured to control the signal generator, wherein the processor causes the signal generator to randomly sweep a frequency of a sine wave in increments of 1 Hertz to generate the plurality of ultrasonic signals.
