Provided in an embodiment of the present invention are a housing assembly and an electronic device. The housing assembly comprises a housing main body having a sound hole and a sound-guiding channel. One end of the sound-guiding channel is in communication with the sound hole. The other end of the sound-guiding channel corresponds to a microphone installed at the housing main body. The sound-guiding channel comprises a first gas storage space and a second gas storage space for decreasing the sound energy density of a sound wave transmitted in the the sound-guiding channel. The first gas storage space and the second gas storage space are spaced apart from each other and sequentially arranged along the sound-guiding channel. In the housing assembly and the electronic device of the present invention, arrangement of a first gas storage space and a second gas storage space in a sound-guiding channel can decrease the sound energy density of a sound wave transmitted in the the sound-guiding channel, such that the so
