With the improvement and improvement of the performance of recording equipment, people's use and development of sound have reached an unprecedented height. But while the development of science and technology brings convenience to mankind, it also produces a series of negative problems. As a high-tech product, the recording blocker is slowly being understood and accepted by people. Its function is to effectively prevent illegal recording, so that people can speak freely without worrying about being secretly recorded.

The problem of voice leakage has always been a worldwide problem. Voice leakage incidents have emerged from all over the world. Some voice information leakage incidents even involve the level of national security. Individuals and organizations have always suffered from not having a good voice information security product. A good solution to this problem.

The traditional recording shielding technology scheme mainly uses a wide frequency range of random pulse sequences to carry out random interference. High-power high-frequency signals cause electromagnetic interference to the recording equipment, causing the input voltage or input current of the front end of the acoustic sensor to exceed the threshold of the acoustic sensor. Can not work normally and achieve effective voice blocking. This method is noise-free, but its main disadvantage is that it only interferes with analog recording equipment and is basically ineffective for new digital recording equipment. At the same time, high-power wireless electromagnetic signals will produce electromagnetic radiation, which is harmful to humans when used for a long time.

Anti-recording equipment has high technical requirements, so there are few independent research and development companies, and they cannot separate the interference sound from the original sound, and thus cannot distinguish the voice information. Eventually achieve the purpose of preventing voice leakage. As the entire society's awareness of privacy protection increases, people's demand for anti-recording equipment will become stronger. Recording blocker The anti-recording blocker can block the recording of sound collection devices such as mobile phones, voice recorders, and recorders, which protects the safety of voice information and allows people to speak freely.

The recording jammer has the characteristics of complete functions and convenient operation. The MDPB-L7B recording jammer has replaced the ultra-quiet fan, and the sound produced during operation is smaller and quieter than the old equipment. The anti-recording effect of digital devices such as voice recorders is at the world's advanced level, which can effectively ensure that conversations are not recorded, thereby ensuring the safety of information, effectively preventing illegal recording without personal permission, and protecting your privacy.

In the working process, the wireless jammer uses true random numbers as seeds, uses high-security encryption algorithms to perform encryption operations, and then processes the encrypted random numbers by mixing high and low frequency sound sources to produce unrecoverable, silent and mixed The interference signal with overlapping effect interferes with the sound collection device, thereby forming a sound shielding effect.

In the field of recording shielding equipment, there is only one device known to people. The shielding effect of mobile phones and digital voice recorders is very good. The sound waves emitted can only be received by digital products such as mobile phones and voice recorders but cannot be heard. Compared with other anti-recorders, there is no buzzing noise, and it can quietly guard the conversation environment, which is not easy to be detected by people, and does not interfere with people. Because the human body does not receive ultrasonic waves, all the mobile phone recordings are noise, but people listen No, it will not affect normal conversation and communication.
