The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current endConnect to supply power to the system. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
The principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
Devices that use the principle of electromagnetic induction for charging, the principle is similar to that of transformers, through the emission endSuction mode The charging mode to achieve the charging effect. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Magnetic charging transmission speed is fast, perfectly compatible with mobile phone data transmission.
Magnetic wireless charging technology is a magnetic way to achieve wireless charging. The advantage of magnetic wireless charging technology is that the device can be firmly fixed on the magnetic base when charging and is not easy to fall off. At the same time, the magnetic base can be adjusted according to the needs of non-equipment, and the charging effect is more stable.
Magnetic charge YesThrough the magnet male and female suction, the charging cable and the socket can be connected to charge. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Wireless charging is a technology that does exist, and the technology has been widely used in electronic devices.
First of all, the principle of use is very simple, AWEI with dimension magnetic charging is through the W10 magnet male and female suction. Secondly, the charging cable and the jack can be connected to charge. Magnetic charging. Finally, as long as the joints are close to each other, AWEI will draw the W10 firmly for 15W with the dimensional magnetic forceWireless fast charging.
1. AirPods do not need to take out headphones when charging. AirPods earphones will be charged in the charging case, the earphone case is equivalent to a charging treasure, after no power connected to the power supply to charge. AirPdosPro is equipped with the H1 chip, which supports the user's voice to wake up Siri, and also supports the active noise reduction feature, which will adjust according to the structure of your ear and the fit of the earbud to reduce the ringAmbient noise and 3 optional earplug accessories.
2, in general, Apple wireless headset charging does not need to move out of the headset, just connect the charging box to the power supply. This design simplifies the charging step and improves the user's convenience, which is a highlight of AirPods design.
3, airpods charging box charging is not necessary to take out the headphones. When the charging case is charging, the headset can be placed in the charging case. AirPods earphone case is actually for the AirPods earphone charging, AirPods earphone case is equivalent to aSmall charging device that can be charged with its own energy storage when the headset is unplugged. The way to charge AirPods is to put the headphones in the charging case. The power carried by the charging case can support multiple charges, so it can be charged at any time.
4, can be taken out, can not be taken out. The Bluetooth headphone charging bin can be charged separately, the Bluetooth headphone bin is equivalent to the exclusive mobile power of the wireless Bluetooth headphone, and the built-in battery provides USB-C or MicroUSB and other data interfaces, so it can be charged directly through the charger, regardless of whether the Bluetooth headphone is in the battery bin.
1. Charging method: The Magsafe charging case is a magnetic charger, which can be directly connected to the iPhone for charging through magnetic adsorption on the back of the iPhone. The wireless charging case transmits power to the iPhone through wireless charging technology. Charging efficiency: The charging efficiency of the Magsafe charging case is relatively high and the charging speed is faster. Because wireless charging needs to transmit electricity through electromagnetic radiation, its charging speed is relatively slow.
2, magneticDifferent devices: Simply put, the difference between the magsafe charging box and the wireless charging box is that the magsafe charging box has more magnetic devices than the wireless charging box, which can be adsorbed on the magsafe charger. In addition to supporting wireless charging and lightning interface charging, the magsafe charging case also supports magsafe charger charging. Different serial numbers: The last four digits of the serial numbers are different.
3, the difference between wireless charging treasure and magnetic charging treasure is as follows: Basic definition Different Wireless charging treasure is a device that provides power for mobile devices through wireless means. itThe use of wireless technology for mobile phones and other devices to charge, with a large power storage capacity, easy to carry and use. Magnetic charging bank is a kind of charging bank with magnetic function.
4, the difference between wireless charging treasure and magnetic charging treasure mainly lies in their charging method and scope of application. To put it simply, wireless charging treasure uses wireless charging technology, which can provide charging services for devices that support wireless charging; The magnetic charging bank is connected to the device through magnetic adsorption to provide wired or wireless charging for the device.
5, the difference between the two is: the use of different, electrical efficiency and so on. Magnetic wireless charging technology is a kind of wireless charging through magnetic mode. The advantage of magnetic wireless charging technology is that the device can be firmly fixed on the magnetic base when charging and is not easy to fall off. At the same time, the magnetic base can be adjusted according to the needs of non-equipment, and the charging effect is more stable.
6, magnetic charging is through the magnet male and female suction, so that the charging cable and the jack can be connected to charge. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Wireless charging is a technology that does exist, and the technology is already widespreadTechnology applied to electronic devices.
2, South Carolina S2 neck headset support magnetic adhesion between the two headphones, hanging on the neck, gently touch automatically adsorbed, convenient when not in use. In terms of headset details, South Carolina S2 still maintains the excellent workmanship of the previous South Carolina Bluetooth headset, with small gaps and neat lines. This also ensures that the S2 can support the waterproof capability of the IP55, which is suitable for sports people.
3, the first point: the traditional ear will block both ears so that you can not hear the environmental sound, thisRunning in conditions can be really dangerous. The second point: the running movement is too large, the headset is easy to fall off the third point: wind noise and stethoscope effect, running fast or when the wind is more obvious, hear the whirring wind and headphones friction, the experience is very poor.
4, the specific feeling is that the music and the external sound are not delayed, as long as you don't listen to the music too much, you will not ignore the sound of people and cars around you.
