Why does the Redmi Note 13 Pro+ 5G produce noise when pressing the battery cover speaker quickly?
The Redmi Note 13 Pro+ 5G features dual stereo speakers with open sound cavity technology. The entire back shell of the phone acts as the speaker sound cavity, allowing air to flow inside the phone. With its IP68 waterproof rating, the device is well-sealed, preventing air from flowing out quickly when pressed hard. This can cause the air to momentarily impact the upper speaker, resulting in transient noise. This noise is brief and will disappear quickly.
Xiaomi products undergo rigorous inspection to ensure quality and performance. This transient noise is a normal phenomenon and does not affect the speaker's performance or the phone's functionality. For an optimal experience, avoid pressing the back cover of your phone too hard and ensure that the pressure relief hole is not blocked during use.
