Based on the above technical solution, optionally, the volume-variable sound cavity 3 in this embodiment includes a sound cavity box 31, an annular folded air bag 32, a cover 33 and a positioning device 34; the sound cavity box 31 is fixedly arranged in the device body 1, one end part of the annular folding air bag 32 is fixedly arranged on the sound cavity box 3 and communicated with the sound cavity box 3, and the other end part of the annular folding air bag 32 is fixedly connected with the sealing cover 33; the positioning device 34 is used for positioning the cover 33 when the annular folded air bag 32 is in a compressed state; the housing 11 of the apparatus main body 1 is opened with a through hole 12 for inserting the annular folded air bag 32.
Specifically, the sound cavity box 31, the annular folded air bag 32 and the cover 33 in the present embodiment form a closed sound cavity structure, while the annular folded air bag 32 in the present embodiment has multiple folded layers, and the volume of the annular folded air bag 32 can be changed by stretching or compressing the annular folded air bag 32, so as to change the volume of the sound cavity 3 with variable volume in the present embodiment. In order to position the cover 33 after the ring-shaped folded air bag 32 is in the unfolded state, the positioning device 34 of the present embodiment positions the cover 33. For example: the positioning device 34 may be a spiral spring, one end of the spiral spring is fixed on the sound cavity box 31, and the other end of the spiral spring is fixed on the cover 33, such as the positioning device 34 in fig. 1 and 2; alternatively, the positioning device 34 may be a spring rod, one end of which is fixed on the sound cavity box 31, and the other end of which is fixed on the cover 33; the positioning device 34 in this embodiment may also adopt a positioning rod or a positioning pin, and the positioning device positions the sealing cover 33 through the positioning rod or the positioning pin, wherein the positioning rod or the positioning pin may be disposed on the outer surface of the housing, and positions the sealing cover 33 after the annular folded air bag 32 is expanded. In addition, the casing 11 of the apparatus main body 1 is further provided with a through hole 12, and the annular folded air bag 32 is inserted into the through hole 12, so that the annular folded air bag 32 extends to the outside of the casing 11 through the through hole 12.
