    摘要: A MEMS speaker includes a substrate, a vibration sounding portion and a baffle plate with a through hole. The baffle plate, the substrate and the vibration sounding portion form a sounding inner cavity, and a volume of the sounding inner cavity can adjust a resonant frequency of the sounding inner cavity, so that the resonance frequency of the sounding inner cavity resonate with a preset frequency of the MEMS speaker. A speaker assembly structure further provided includes a speaker, a fixing portion, and a baffle plate, the speaker and the baffle plate together enclose and form a sounding inner cavity, the fixing portion and the speaker are fixedly connected together and form a sealing structure. A sound pressure level of the MEMS speaker and the speaker assembly structure is high and harmonic distortion of the MEMS speaker and the speaker assembly structure is small.

    摘要: A screen sounding device and a display device are disclosed. The screen sounding device includes a sounding structure. The sounding structure includes a first electrode, an insulating layer, and a second electrode stacked in sequence. A sounding cavity is formed between a vibrating portion of the second electrode and the insulating layer. The first electrode and the second electrode receive different driving signals, and the vibrating portion can drive the air in the sounding cavity to vibrate and sound. The screen sounding device of the present disclosure has a desirable sounding effect, various setting positions, and low manufacturing costs.
