摘要： 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.
