by playing specific sound frequencies or vibration patterns. Results may vary depending on device model,
speaker condition, blockage type, water exposure, volume level and environmental conditions.

hardware damage, liquid damage, speaker defect or audio malfunction. If your device has been exposed to
water or suffers from hardware damage, you should contact Apple or an authorized repair provider.
