With the continuous development of technology, more and more mobile phones gradually cancel the 3.5mm headphone jack, making wireless headsets gradually become one of the must-haves of digital products. TWS Bluetooth headset enables wireless headsets to achieve true stereo sound, allowing wireless headsets to achieve left and right 2 channels of sound playback, while also achieving stability and low latency, making people feel like they are on the scene. In the European market, TWS Bluetooth headsets are also one of the most popular best-selling products in the headsets, but CE certification is used as an access certificate for the European Union market, and wireless headsets and headset charging boxes that want to export to the EU need to obtain CE certification.

Tablet PC is a wireless electronic product that everyone is very familiar with. Also called a tablet computer, it is a small, portable personal computer with a touch screen as the basic input device. It has a touch screen (also known as tablet technology) that allows users to perform tasks with a stylus or digital pen instead of a traditional keyboard or mouse. Users can input through the built-in handwriting recognition, soft keyboard on the screen, and voice recognition. Tablet PCs exported to the EU or sold in the EU market must be subject to EU mandatory CE-RED certification.

Wireless charger is the abbreviation of wireless charger, English Wireless Charger. Wireless charging is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By placing a coil at the sending and receiving ends, the sending end coil sends an electromagnetic signal to the outside under the action of electric power, and the receiving end coil receives the electromagnetic signal And the electromagnetic signal is converted into electric current, so as to achieve the purpose of wireless charging. However, the export of wireless chargers to the United States generally requires FCC-ID certification.

A wireless keyboard refers to a keyboard that performs wireless transmission through the Bluetooth protocol and performs Bluetooth communication within an effective range (within 10m). In fact, it is a short-distance radio technology, using \"Bluetooth\" technology, can effectively simplify the communication between handheld computers, notebook computers and mobile phones and other mobile communication terminal devices. However, if you want to export wireless keyboards to Japan, you need to apply for MIC certification.

In recent years, with the improvement of people\'s consumption level, the sales market of wireless headsets has also become larger and larger. Compared with wired earphones, wireless earphones have little difference in sound quality, but wireless is more convenient, mainly because the middle line is replaced by electric waves. The wireless earphone is the middle wire is replaced by the electric wave, which is connected from the audio outlet of the computer to the transmitting end, and then sent from the transmitting end to the earphone at the receiving end through electric waves. However, the export of wireless products such as wireless headphones to Europe requires CE-RED certification.

Wireless projector refers to a projector that takes wireless transmission technology as its core and realizes projection through wireless transmission. Through the wireless module, connect to the projector through the HDMI socket, through the wireless projector, the screen on mobile phones, tablets, computers and other devices can be synchronized to display or transmit music, videos, pictures and other content to the large screen in real time. On the premise of not losing the quality of the projection image, to provide users at all stages with a trendy and convenient application experience. EMC testing is required. Welcome to ZRLK testing for processing!

FCC-ID is one of the compulsory FCC certification models in the United States and is suitable for wireless products. Products with wireless transmission frequencies, such as Bluetooth devices, WiFi devices, wireless alarm devices, radio receiving and transmitting devices, phones, computers, etc., need to apply for FCC-ID certification. The certification of wireless products is directly approved by the FCC TCB agency, and the certification can be checked on the official website of the FCC in the United States.

The wireless charger is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By placing a coil at the transmitting and receiving ends, the transmitting end coil sends an electromagnetic signal to the outside under the action of power, and the receiving end coil receives the electromagnetic signal. Signal and convert electromagnetic signal into electric current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special power supply method that does not require a power cord and relies on electromagnetic wave propagation, and then converts the electromagnetic wave energy into electrical energy, and finally realizes wireless charging. However, the export of wireless chargers to Europe requires CE certification before they can be sold.
