Second: JBL Go 2 speaker. The speaker's compact, waterproof design is one of its highlights, and its simple appearance mainly features the JBL white logo. The keys feel hard, easy to operate. The side of the speaker has a rubber strip to protect the charging interface and audio interface, which can support charging or wired connection. The JBL Go 2 speaker is standard and the workmanship is good, but it cannot be compared with several light sculptors in sound quality and design. The third: Elvis smallThe Prince speaker.
The speaker adopts a design that can be placed flat or tilted, so that it can also become a multi-angle mobile phone stand by the way, which is quite practical. The buttons and charging port are designed in a relatively low-key place, without affecting the overall minimalist appearance. The handle of the speaker is still a desk lamp or an atmosphere lamp. When the speaker is charging, put on the mobile phone, and the mobile phone will start wireless charging.
From the experience point of view, the magnetic car bracket is undoubtedly the most convenient, but on the other hand, for some mobile phones with heavy fuselage, there may be sliding phenomenon when the road is bumpy, and for the usual wireless chargingRack wireless fast charge is where the electricity , note that some wireless charging panels support different mobile phone models Mobile phone rack wireless fast charge is where the electricity , according to their own mobile phone model to choose wireless charging panel.
2, wireless chargers and mobile power in addition to mobile phones and other 5V equipment can be charged Mobile phone rack wireless fast charge is where the electricity , there is no other connection. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cordThe advantage of the technology is its convenience and versatility. The disadvantages are low efficiency and can only provide electrical energy. Mobile Power Pack (MPP), also known as "power bank".
3. Open the mobile phone jacket, plug the receiving module into the charging port, connect the patch to the charging port of the mobile phone, and then put it on, remember to face up. Since the energy is transmitted between the charger and the electrical device by a magnetic field, no wires are connected between the two, so the charger and the electrical device can be exposed without conducting contacts. It is important to note that whether it is a mobile phone or a charging bank itselfStandby wireless function, that is, wireless coil.
1, wireless charging mobile phone rack wireless fast charge is where the electricity principle: electromagnetic induction. Charging base and mobile phone terminal respectively built-in mobile phone rack wireless fast charge is where the electricity coil Mobile phone rack wireless fast charge is where the electricity , when the two are close, the coil is based on a certain frequency 2, the principle of wireless charging is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end will form eddy currents in the magnetic field, and the mobile device end is connectedThe winding coil senses this eddy current. In this way, power is transferred from the charger to the mobile device. 3, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field 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 end to supply power to the system directly. 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.
