Anonymous users2024-02-07Lightning is a Lightning Dock interface released by Apple in 2012On September 12, 2012, Apple released a new Lightning Dock interface at the Parkview Green Convention Center in San Francisco, USA, which can be translated as "lightning" interface in Chinese. The release of the new interface standard also means that the 30-pin dock interface that Apple has used for 9 years will be officially replaced. After the release of the lightning interface, many fans complained about it.
Lightning interface function:
In addition to basic charging and data transfer, it also supports digital signal output functions such as ** and audio. Currently, the only Lightning interface used by the iPhone and iPad series is about 25MB-35MB S.
The Lightning connector also moves the fixed mechanical clasp used by the previous generation of 30-pin connectors into the base interface, so the connector itself has no moving parts and is compact and less prone to damage. Small grooves are provided on the left and right sides of the connector to fit the retaining buckles in the interface. In addition, there is the problem that the metal pins of the lightning wire are exposed, and there is a certain risk of short circuit.
After the actual test by the FIX engineer, the lightning cable has no voltage output in the no-load state (the power supply is not connected to the load).

Anonymous users2024-02-06<> lighting interface is used on Apple devices, compared to the interface, the lightning interface can make the headphones more intelligent. The two-way connection between the earbuds and Zenruler Apple products is conducive to noise cancellation, improves sound quality, and even has the potential to become a biosensor; Headphones can also be made lighter, and the lightning connector will free up design space and make the product thinner.
Another disadvantage of the lightning connector is that it does not support the audio output of analog signals, as mentioned earlier, it is a "pure digital" interface. This is somewhat similar to the difference between the DVI interface and the HDMI interface. In other words, in the future, if accessory manufacturers, such as speaker manufacturers, launch speakers that specifically support iPhone 5 or iPod, then they must also use digital signals completely, or must integrate a "digital-to-analog converter (DAC)" into the speaker, which may lead to higher costs.

Brief introduction. Another disadvantage of the lightning connector is that it does not support the audio output of analog signals, as mentioned earlier, it is a "pure digital" interface. This is somewhat similar to the difference between the DVI interface and the HDMI interface.
In other words, in the future, if accessory manufacturers, such as speaker manufacturers, launch speakers that specifically support iPhone 5 or **iPod, then they must also fully use digital signals, or must integrate a "digital-to-analog converter (DAC)" into the speaker, which can lead to higher costs.
Apple's Lightning to 30pin adapter doesn't support output and iPod mode. It may be a bit troublesome for users who have used the iPhone to connect the projector before, because you may no longer be able to use the previous cable to connect to the official Lightning to 30pin adapter and then connect to the iPhone 5 to make the projector work, and you must buy the iPhone 5 to connect the projector directly to the cable.
And iPod mode is a special mode that has the function of displaying the on-screen menu on the iPod directly to the display of some accessories themselves. Apple's description on the official product introduction page of this adapter is very implicit, only saying that this adapter may not be able to support some 30pin accessories.
The front and back of the contact lens are actually very different, put the lens on the fingertip, and observe the lens at the edge, in a bowl, deep depression for the front. It is dish-shaped, and the shallower depression is the opposite side. Look at it a few more times and you'll understand. >>>More

Anthurium has tillering properties and can be used for branching propagation. When Anthurium sprouts a new plant at the rhizome of the mother plant, it can be cut off from the mother plant and replanted to form a new plant. The propagation method of ramets is simple, easy to survive, and the vegetative growth period is short, and the ramets can bloom after 1 year, but the materials are difficult to sterilize, easy to carry pests and diseases, and the reproduction coefficient is low, the individual growth cycle of plants is inconsistent, and when the number of ramets is high, the phenomenon of variety degradation will occur, which is not suitable for large-scale commercial production. >>>More
