Huawei mate30pro mobile phone vibrates obviously.

The launch conference of Huawei mate30 series National Bank Edition will be held on September 24th. In order to feel the charm of the new mobile phone in advance, many small partners have experienced offline. Some netizens reported that the shell vibration was very obvious after Huawei mate30pro sound was played. I wonder if this phenomenon is normal.

Huawei mate30pro mobile phone vibrates obviously. In order to improve the sound quality of calls and music playback, Huawei mate30pro cancels the receiver and keeps the speaker, and uses the screen to make sound, which may easily cause the screen or the back shell to vibrate. The vibration is normal, and the vibration intensity meets the industry requirements.

Screen exciter scheme adopted by Huawei p30pro screen vocalization

Huawei mate30pro is not the first model to adopt screen sound technology, and the previous Huawei p30pro also adopted this scheme. In Huawei p30pro, the audio exciter is tightly fixed on the screen. The audio exciter converts electrical energy into mechanical energy through the electromagnetic induction principle of magnets and coils, and drives the screen to vibrate (the principle is similar to the traditional moving-coil speaker, except that the vibration unit is replaced by the screen). When the vibration propagates from the screen, the sound has certain directivity, but the privacy is still difficult to achieve the effect of traditional speakers.
