Do all IPAD's use the Safari browser?

From Google: If you're experiencing no sound on web pages when using Safari on your iPad, there are several potential reasons and solutions. First, check your iPad's volume and ensure it's not muted or set too low. Also, verify that your device is not in silent mode, either through the physical switch or Control Center. If the issue persists, try restarting your iPad or resetting all settings (but be aware that this will erase saved Wi-Fi passwords and other settings). You can also check for software updates and ensure the website's audio isn't muted within its settings.
