Why does the motor on the Xiaomi 17 Ultra make a buzzing sound?
If you hear a faint humming or buzzing sound when the Xiaomi 17 Ultra vibrates, please refer to the following explanation:
1. The sound is generated by the internal linear motor during vibration feedback. Mechanical motion naturally produces a subtle acoustic response.
2. The vibration system is engineered to provide clear and precise tactile feedback, which can be accompanied by a light audible tone.
3. The motor and its acoustic characteristics are tested under strict quality control standards before shipment.
4. The sound level remains within normal operational specifications and does not indicate a malfunction.
5. This is a normal operational characteristic of the vibration mechanism. Please use the device with confidence.
