The slow-motion video shows the Apple Watch’s unique water resistance

Popular YouTube channel The Slow Mo Guys has just posted an interesting new video. This slow-motion video explains the Apple Watch’s unique water resistance, which is to use an external speaker to create sound waves that push liquid out of the body and prevent it from getting inside.

Available on all Apple Watch models, from the Apple Watch Series 2 to the Apple Watch Series 5, the Water Lock feature is an option in the Control Center, which prevents water from entering inside the watch while the user is swimming. . It also helps to remove residual liquids from the speaker, after the Apple Watch is flooded.

Like conventional speaker systems, the miniature mechanism in the Apple Watch is designed to transmit sound waves into the air. If the diaphragm is exposed to liquid, sound waves will not be able to propagate and produce sound accurately.

To prevent this from happening, the Apple Watch can emit a series of sounds at low frequencies. It causes rapid vibrations and pushes the liquid out. As in the video of The Slow Mo Guys, we can see the Apple Watch has pushed a large amount of water left inside.
