In the audio, the distinctive and subtle hum of an Apple iPhone vibrating can be heard. The sound is amplified as the device is placed on a wooden table, which seems to echo and enhance the vibration. The sound captures the typical scenario of a silent mode iPhone receiving a notification - it's a familiar, rhythmic buzz that most Apple users would instantly recognize. Despite the phone's silence, the vibration is strong and clear, indicating an incoming call or message. The iPhone's vibrations resonate through the wooden table, creating a unique sound that subtly fills the quiet room.
