iCloud: Play a sound on your device
If you lost your device and you think it’s nearby, play a sound on it to help you find it. If you have Family Sharing set up, you can also play a sound on a family member’s device. For more information, see the Apple Support article Family Sharing.
If you only see Pages, Numbers, Keynote, and Settings on iCloud.com, your account just has access to iCloud web-only features. To gain access to other iCloud features, set up iCloud on your iOS device or Mac.
Click All Devices, then select the device on which you want to play a sound.
In the device’s Info window, click Play Sound.
After the sound plays, a confirmation email is sent to your Apple ID email address.
