Interference generator for speakers, headphones?

Good morning.
If you recall some kind of movie about spies, there is a spy in headphones and eavesdrops on the "client", the client is aware that he is being eavesdropped, brings some kind of device to the microphone, the spy pulls the headphones off his head, tk. unbearable squeak in the headphones.
1. Is there any software or do you need to solder something like this (maybe they already sell it on aliexpress) in order to make these same noises on headphones / speakers for / on a PC ??
2. What to read about this?

This simplest device will allow you to interfere with almost any antenna or wire. Now you are subject to the TV, computer and phone.
The material is provided for informational purposes only. The author and the editors are not responsible for harm from using the device.
Run to the kitchen! It has everything you need for a burst of accumulated radioZZZZZlost. How? Don't you have an oscilloscope, soldering iron and radio components? And you don't need them. We assemble this device exclusively from kitchen utensils. A real radio pest will do without components and devices, because he can make a device out of cookies, like in Hollywood films. Poor Americans, they never dreamed of what was happening in our kitchens. Welcome to our little kitchen hell.
ZLO device capabilities
The device sucks electrical noise into almost any cable: television, telephone, network, power. Naturally, you don't need to join. It is enough to bring radioZLO to the cable. With a TV, the device works at a distance of several tens of meters.
There is interference on the TVs. Computers under the influence of the kitchen ZZZla reboot. The device causes the speakers of some phones to hiss. Not all possibilities are fully known, research is ongoing.
The device can easily burn household appliances such as a TV, center, computer, office PBX. Attention! Vacuum cleaner, food processor and coffee grinder, this version of kitchen evil cannot burn. The device is being improved.
ZLO components, evil tools
For the simplest radio Z, you need a kitchen piezo lighter. Most happy owners of gas stoves have such a lighter. In order for your stove to begin to diligently smoke into the ceiling and around, you need to start the combustion process with such a lighter. You can get an EVIL stove burner at any hardware store or at a regular clothing market, wreck, or trinket stand. Piezoelectric happiness will cost 30-50 re. You will also need a regular wire. You can cut it off from a TV set, a vacuum cleaner, a food processor, a computer, a coffee grinder and, I'm not afraid of this word, a Refrigerator. The main thing is that the wire that you cut must be disconnected from the network. Remember: cutting off electrical wires connected to the network dramatically reduces the number of radio pests around the world.
If you train your moZZZZg, then after reading the article you can easily replace the kitchen piezo lighter with a cigarette lighter or with any other sparking device. But in the first experiments, the Good Doctor prescribed you exactly the kitchen. The kitchen lighter is perfect for our dirty purposes. No, this is not an advertisement for kitchen piezo lighters, read on!
If there is nowhere to cut the wire, then you can easily buy it at the clothing market, at the hardware store, or just find it in the trash. You need a wire of any thickness, from one to five meters long. Of course, the more, the better, but in the five-meter you will get tangled in your legs. Here the rule works: "let it be small, but cheerful."
Two teaspoons may be useful. Although there will be canteens. You also need tape, a knife or scissors.
ZLOpreparation, that is, the preparation of kitchen evil
First of all, you need to remove the protector from the lighter so that the most delicate, sweetest part of the lighter is exposed - sparkling contacts. Already at this stage, you have received a fun game: "Punishment from heaven." Now you can run after your friends and, like Zeus the Thunderer, throw angry lightning at sinful asses. This is not an advertisement for kitchen lighters, but I want to note that a kitchen lighter with the tip removed is very ergonomically placed in the hand. I just want to stick it in someone's juicy buttock.
The nice thing is that lighters give out a small current, it is unlikely that you can kill anyone with them. But if, nevertheless, someone throws back the skates from the impact of piezoelectricity, then do not forget that we and the editors are not responsible for this. And do not try the lighter on the tongue, it will be wildly painful!
EVIL Generator!
Now sit down in front of the TV and flick the lighter. No interference, of course, is not visible. The thing is that there is no antenna. It is enough to lean a spoon, knife or any other metal object against one of the contacts, as interference will appear on the screen.
And the secret is that any spark emits interference in a wide radio range. What you just collected from a spoon and a lighter is an analogue of the first spark transmitter. Having muddied the simplest detector receiver, you can establish radio communication in Morse code for several kilometers. If you make a good antenna. Approximately such things were twisted (the circuits began to be soldered with the advent of lamps) by the pioneers of radio: Popov, Marconi, Hertz and others.
Spark transmitters were abandoned due to their large size, lack of fine tuning. And most importantly, such a transmitter hissed over a very large radio band. But that's exactly what we need!
How to radiate EVIL?
Radio interference generator - any piezo lighter and in general any sparking device. But a generator alone is not enough. Interference must be emitted so that they reach dear viewers and radio listeners, as well as those who like to talk on the phone. An antenna is needed to emit interference. And only with an antenna, an innocent lighter turns into a ZZZ frontal jammer.
The simplest option is to attach a metal object to one of the spark contacts. If you decide to seriously harm someone, then the wire from the vacuum cleaner or kettle comes into play. Yes, any wire. The end must be cleaned with a knife or scissors. It is enough to insert a well-cleaned end into a plastic holder, from where a spark contact sticks out. In the sense of the wire, you need to strip the end and insert it. And the longer the wire, the farther the signal travels. In this case, the location of such an antenna will affect the effectiveness of interference. How to set up EVIL?
If you are building pocket evil, then teaspoons will be a good antenna. You can fasten one or two spoons to the lighter with tape so that they fit snugly against the contacts. I connected the spoons and contacts with wires pulled from the wire. The emitter from spoons is worse, but compact.
You need to sit in front of the TV and click the lighter. Try different antennas, try to twist the antenna in different directions. You will see the result immediately, it cannot but work. At first, rare dots will crawl across the screen, it is better seen on a dark screen. Press the button more often, there will be more dots on the screen.
The effect will increase if the spark contacts are bent towards each other. So that a very small spark jumps. In this case, the noise density will increase. And the lighter will not click, but creak and squeal like a DJ vinyl. So I was able to bring my TV to crazy. The main thing is that the gap between the contacts is microscopic.
Phone EVIL
If you bring the antenna closer to the telephone cable, then the beeping of the lighter will be heard very loudly in the speaker. Spoons work from ten centimeters, and the wire jams the phone at a distance of a meter (on my phone "RUS"). The main thing is that the antenna is parallel to the telephone cable. After experimenting with kitchen evil, my friends began to complain that something scratched, shoots and whines in the ear. The closer you bring the antenna to the telephone cable, the louder the noise. If the power is not enough, then you can try to wind the telephone wire around the antenna. Carefully! The phone may be damaged. You can jam telephone conversations wherever there is a telephone cable.
Computer EVIL
If you do not want to part with your iron horse ahead of time, then it is better to turn it off for the duration of the experiments. Several times my computer froze and rebooted under the crackle of a lighter. I think that if you bring the antenna close to the wire of the keyboard, mouse or monitor, then you can easily burn the interface. Although I haven't checked.
Competition for the best evil
Kitchen Evil is still quite small and green. Taking advantage of the embryonic state of evil, good will, of course, win again. This cannot be allowed, because. pink snot all have long been taken. Therefore, I announce a competition for the best kitchen evil. There's a lot more to think about. How does radio evil affect cell phones and cordless phones? What will happen if you equip an entire army of friends with lighters? Is it possible to jam a computer, local grid? How to further enhance the effect? What else can be collected in the kitchen?

On K155LA3 they make an interference generator. It
creates such a background signal that VHF signals are not caught within a radius of 10m.

You misunderstood the spy movie. The miracle device did not direct the squeak into the headphones directly to the head phones, but still on the air, overloading the input of the receiver used by the spy.
A device that will interfere directly with headphones (or speakers) will emit such and such power that people from an organization called "Where to go" will immediately become interested in you. And the neighbors will not be very happy, I would be the first to come to meet such an innovator and gently pat his head with a meat grinder. And your own health will undermine.
You should go to the radio circle, buddy. You will learn how to assemble such jammers on your knee there in a few months.

I saw such films: there they threw a bug for wiretapping into a food processor and chopped it .. =)

And I fought with such a generator with neighbors in a rented apartment. Inadequate listened to music around the clock. Because of the hum in the speakers, they handed over the music center for repair 2 times. And in the end they took him away from the apartment. By the way, I collected it on a solid label from under socks :)) The scheme was identical to the one that was already given above. Analog K155LA3 is SN7400. I took power from the crown at 9V. and worked great! K155LA3 at a flea market they can pour you a couple of reapers.
