As shown in fig. 1, the audio jammer body 210 includes a noise excitation unit connected to the main control unit, a transducer connected to the main control unit through a noise driver, and a power supply for supplying power to the audio jammer.
The noise excitation module is used for generating white noise. White noise means that the power of frequency components in a piece of sound is uniform over the entire living room range (0-20 KHZ). This sound sounds a very noisy rustling sound as the human ear is sensitive to high frequencies. White noise is a random noise whose instantaneous value is randomly varied, whose amplitude satisfies a normal distribution with respect to time, has a continuous noise spectrum containing noises of various frequency components whose power spectral density is independent of density, whose distribution of several frequency energies is uniform, whose energies output at equal bandwidths are equal, and whose outputs in linear coordinates are straight lines parallel to the abscissa. In the logarithmic scale, the output rises with a slope of 3db per octave bandwidth, and in the frequency range of the human ear living room, the noise having the same energy becomes white noise. White noise is a flat line in the full spectrum, seen on the graph of the spectrometer.
The main control unit amplifies the white noise generated by the noise exciting unit through the noise driver and outputs the driving level of the amplified signal to the transducer.
The transducers convert the received signals into vibrations of the same frequency. The transducers convert the signal into mechanical vibrations in two ways: 1. magnetostriction, 2, the inverse of the piezoelectric effect. The preferred energy converter can be an electric ceramic energy converter, and the reverse effect of the piezoelectric effect is applied to effectively provide the output power of the energy converter.
