    Abstract: The present invention discloses a sound wave filtering structure. The sound wave filtering structure comprises a cavity wall, a cavity cover and a slit. The cavity cover is mounted on the cavity wall. The cavity wall and the cavity cover are combined to form an inner cavity. The slit is formed on the cavity wall and/or the cavity cover. The cavity wall and the cavity cover seal the inner cavity. A space in the inner cavity is communicated with the outside only through the slit. On the other hand, the present invention further provides a side sound generating speaker module. The side sound generating speaker module at least comprises a side sound generating cavity and the above-described sound wave filtering structure. The side sound generating cavity is configured to guide sound waves to be transmitted from a side surface of a single speaker body. The sound wave filtering structure is arranged on the side sound generating cavity. The slit faces the interior of the side sound generating cavity. The sound wave filtering structure provided by the present invention can adjust and filter high-frequency sound waves. Especially, in the side sound generating speaker module, the sound wave filtering structure can significantly improve the sound quality of the high-frequency sound waves.

    Abstract: The present invention discloses a differential capacitive MEMS pressure sensor and a manufacturing method thereof. The MEMS pressure sensor includes a sensitive structural layer, which includes a common sensitive part and a common supporting part located on the edge of the common sensitive part, a thickness of the common supporting part being larger than that of the common sensitive part; and the MEMS pressure sensor also includes an upper fixed electrode structural layer and a lower fixed electrode structural layer which are vertically symmetric relative to the sensitive structural layer and used for forming differential capacitors with the common sensitive part. According to the MEMS pressure sensor of the present invention, by the differential capacitor structures, inhibition of chips on common-mode signals is enhanced, and a signal to noise ratio of output signals is improved. Meanwhile, the thickness of the common supporting part of the present invention is larger than that of the common sensitive part, such that the peripheral common supporting part can shield strains caused by temperatures and stresses. Therefore, the strains transmitted to the common sensitive part because of temperature and stress changes are greatly reduced, and temperature stability and stress stability of the chips are improved.
