This kind of anti-radiation earphone for mobile phone was developed by Zhu Aidao, an expert in China, and has obtained German patent and China invention patent before. According to relevant international treaties, patent applicants will be granted patent protection by the International Bureau of the World Intellectual Property Organization, and at the same time, they will be granted patent protection by 150 countries and regions.
According to the testing of third-party testing institutions such as the National Telephone Exchange Quality Supervision and Inspection Center, this kind of radiation-proof earphone can effectively reduce the radiation threat faced by consumers when using mobile phones. The test report shows that the radiation of ordinary headphones is 63MG, that of Bluetooth headphones is 19.8mg, and that of this kind of radiation-proof headphones is only 1.2mg, which means that the radiation of consumers using this kind of radiation-proof headphones to answer mobile phones is only 1/52.5 of that of ordinary headphones directly, and only/kloc-0 of those using Bluetooth headphones to answer calls.
Invented the anti-radiation earphone, integrated a variety of anti-radiation technologies, especially by changing the structure of the traditional earphone, separating the earplug from the speaker and isolating the earplug from the radiation source of the mobile phone; With the unique sound channel technology, there is no metal wire in the sound channel, which also greatly reduces the radiation magnetic field.
