[* black] Remember the missing earpiece speaker grille on the front? That's due to the "HUAWEI Acoustic Display Technology"-speaker, which works like a [https://electronics.howstuffworks.com/gadgets/audio-music/vibration-speakers2.htm|vibration speaker aka structure-borne driver|new_window=true].
[* icon_note] This kind of speaker works almost like a "usual" speaker. But instead of havingvibrating a membrane that resonates and produces theto produce sound waves, this technology usesvibrates a rigid surface (the glass of the screen) to generateinstead, converting the sound waves by making that surface vibratescreen into a speaker.
[* black] The driving part of this module consists of a coil and a magnet in the middle. The otherIt is coupled with the part that vibrates the screen, which is glued to the back of the display and induces its vibration to the glassdisplay.
