Will Apple's silent alarm clock ring?

Apple's mobile phone is silent, and the alarm clock will ring when the volume is normal.

Because the mute of Apple's mobile phone and the ringtone of the alarm clock belong to different volume adjustment systems, after the mute of Apple's mobile phone, both incoming calls and text messages will become vibrations, but the ringtone of the alarm clock is still valid at this time. Because the alarm clock is a separate volume adjustment system, it does not communicate with the system volume.

On this basis, you can switch the position of the speaker and microphone-the speaker is placed on the right. The volume control of all iPhone is on the left, while the volume control of iPod is on the slide button of the application.

In the first five series of iPhones (before iPhone(iPhone 4s), there is a device with a TRS terminal with a diameter of 3.5 mm at the upper left of the mobile phone, which is used to connect sound output (such as headphones), and the subsequent iPhone series will be placed at the lower left.

Because of the special design, most of the audio devices of the first generation iPhone are not suitable and need an adapter to use. The following series can match most audio devices with iPhone through the embedded earphone socket, and the problem is eliminated.

Apple's own headphones have a multifunction button near the microphone, which can be used to play or pause music, skip, and answer or exit calls without touching the phone.
