The speaker module includes a speaker unit and a module housing, the speaker unit is mounted in an inner cavity that is encircled by the module housing, and a closed rear acoustic cavity is formed between the speaker unit and the module housing; the speaker unit is provided thereon with a unit leakage holes which is in communication with the rear acoustic cavity, and an air-permeable separation element is fixed on the unit leakage holes; at least one porous material frame is disposed in the rear acoustic cavity; a region other than the porous material frame disposed in the rear acoustic cavity is filled with sound-absorbing particles. The technical solution provided by the present disclosure may reduce the resonance frequency fluctuation range of the speaker, thereby improving the acoustic performance of the speaker module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speaker module and electronic device","description":"Provided in an embodiment of the present disclosure are a speaker module and an electronic device.
