As a brand-new high-tech product, the recording shielder has gradually entered people's field of vision. It can prevent illegal recording and protect the privacy and safety of your conversations in many occasions! The principle is: the recording shield sends out a The interference signal makes the pickup (microphone) of the sound acquisition device fail, so that it can only pick up the interference signal, but not the normal voice signal, thus achieving the purpose of voice shielding. After the jammer is turned on, the files recorded by the recording equipment are played with a "humming" sound and the content of the conversation at that time cannot be heard. This product is widely used in confidential meetings, high-end business talks, military meetings and other places to prevent illegal recording. There are many types and forms of recording shielding products on the market. How to choose a good recording shielding product has become a problem that needs to be solved.
So, what constitutes a useful and practical anti recording blocker product? According to the author's many years of investigation, a qualified product should follow the following points:
1. Yozib olish uskunasining eng so'nggi modeli ekranlangan bo'lishi mumkinmi, bu ko'rib chiqilishi kerak bo'lgan birinchi savol. Masalan, iphone, iphoneX/XR/XS/max va boshqalarning eng soʻnggi modellari. Hammamizga maʼlumki, joriy yozib olish uskunasi shovqinni kamaytirish va dasturiy taʼminot va apparat vositalarida filtrlash bilan ishlab chiqilgan boʻlib, buning uchun yozib olish ekrani texnik jihatdan integratsiyalashuvini talab qiladi. bu eng so'nggi yozish uskunalari. Bundan tashqari, uni malakali mahsulot deb hisoblash uchun yaxshi himoyalangan bo'lishi mumkin, bu mahsulotni tanlashda e'tiborga olinishi kerak.

2. Whether the audio recording jammer will cause discomfort to the human body after it is turned on is a very important issue. The recording shielding device realizes shielding by emitting shielding signals. The frequency and algorithm used by different manufacturers of the shielding signal are very different. The frequency and algorithm determine people's feelings and shielding effect. According to the author's investigation, after many products start working There will be sharp or harsh sounds, which will make people feel uncomfortable. Such products should be avoided as much as possible.
3. Uni har tomondan himoya qilish mumkinmi? Bozordagi ko'plab murabbolarning aniq kamchiliklari bor, ya'ni ekranlash effektiga faqat yozib olish murabbosi yozib olish moslamasining (masalan, mobil telefon, ovoz yozish moslamasi va boshqalar) pikapiga qaraganida, bir marta pikap va yozish to'xtatuvchisi burchak hosil qiladi. Va asta-sekin o'sib boradi, himoya ta'siri asta-sekin zaiflashadi. 180 darajaga yetganda, ko'pchilik yozib olish qalqonlarida ekranlash effekti yo'q. Bu nisbatan batafsil va nisbatan professional muammo. Tajribaga ega bo'lmaganlar buni tushunishlari qiyin. Tasavvur qilish uchun biz quyidagi diagrammadan foydalanamiz:
