  Recording jammers can help you when you want to talk to old friends or talk at the dinner table without wanting the content of the conversation to be leaked or made public. Just turn on the switch button, it will emit a harmless ultrasound that exceeds the threshold of human hearing, and the sound of normal conversation will be submerged in random noise.


  Voice recorder can help us record some work, study or life things, which can bring great convenience to users, which is also an important reason why it is so popular now. However, if we are talking with others, the content of the conversation or learning knowledge may involve privacy and other issues, and we don't want these content to be recorded by another person with a voice recorder. There are many styles of recording pens now, as small as a pen. If someone insists on recording, it is generally undetectable. In this situation, what should we do?

  According to previous tests, there are not too many methods that can effectively interfere with the recording of the recorder. This is because the current recording pen was designed with this in mind, and its anti-interference performance is much better than the recording products of previous years. I remember when a test was conducted in 2007, when a modern Korean voice recorder was recording sound, as long as there was a magnet with a diameter of 40mm on the side, it could interfere with the normal recording of the recorder, resulting in the final recorded sound because of the magnetic field. Influence, and become blurred. If there is a small motor on the side, the effect of interfering with the recording is even stronger.

  Up to now, many recording pen design manufacturers have made special reinforcements for this aspect. Even if the motor and the recording pen are close together, the recorded sound will not deviate greatly from the actual sound. However, some manufacturers have specially developed "recording pen jammers" for the needs of users, which can effectively interfere with the normal recording of the recording pens.

  In the past, we also used a voice recorder jammer to test the effect of interfering with the voice recorder. When the jammer was turned on, the recorded sound effect became very poor, and it was almost impossible to hear what people were talking about. This kind of recorder jammer uses the principle of magnetic field and the principle of radiation to specifically target the interference of audio recording. The interference effect is relatively successful in dealing with recording devices such as voice recorders and tape recorders. If you don't want to be recorded illegally by others when you are in a social conversation, then the most effective way to interfere with the sound recording of the voice recorder is to use this voice recorder jammer is a good choice.

  The protection range of the recording jammer is similar to a cone-shaped space, the interference range is about 15 square meters, and the interference distance to most mobile phones and other digital products is more than 2 meters, which can form a safe space. In this space, there is no need to worry about being Recording by others. It can effectively interfere with digital devices such as mobile phones and voice recorders. The anti-recording effect is at the advanced level in the world. It can effectively ensure that conversations are not recorded, thereby ensuring the safety of information. The sound waves emitted can only be received by digital products such as mobile phones and voice recorders. The inaudible sound has no buzzing noise compared to other anti-recorders.
