What is Lock Sound on iPhone?

Have you ever wondered why your iPhone makes a sound anytime you turn off your iPhone screen? Are you curious to discover the reason for your phone’s sound once you turn the screen back? This article will uncover all you need to know about Lock sound on iPhones.

iPhone devices can play audio alerts from movies, videos, and even text messages. Still, if you’re an empathetic person, you’ll find that there are other noises that iPhones make that fall under a different category, and one such is ‘Lock Sound.’

We often consult our Sound Menu when changing our ringtones or text messages’ sound. However, we need to realize that many other settings can be done on our sound menu, as these options are relatively small.

If you are just like me, who love changing my ringtone frequently, then it’s obvious you must have come across other options like lock sound and ponder whether to turn it on or leave it off. 

Lock sound is a silent beep or doorbell-like sound you hear anytime you push the side button of your iPhone to either Sleep or Wake option. The sound helps notify locked devices without you having to look at the phone screen.

If you’re an iOS user who utilizes her iPhone keypad very well, then you’ll agree with me that there is some clicking sound you hear whenever you type something on your iOS keyboard. In addition, the lock sound is an extension of the sound you hear whenever you order on a keyboard.

Most people love hearing these sounds when they type and put their device to sleep, while this sound is annoying and unnecessary to others. 

Lock sound only sounds whenever you put your phone to sleep. Once you push the power button to enable your iPhone screen to come on, the same sound gets played in the background. The sound helps you know the current status of your device, so you don’t need to stay glued to the device to see when the screen is on and turned off.

So, to be precise, a lock sound refers to the sound beeping backward when you lock your iPhone device or turn off the power button. It also refers to the beeping sound you hear when you take a snapshot or type on a keyboard.
