The cover plate is fixed to the housing and forms a sound cavity with the housing. The cover plate is provided with a ventilation channel to connect the sound cavity with an external space. The ventilation channel includes a first channel and a second channel that communicate with each other. The first channel extends along the thickness direction of the cover plate, and at least a portion of the second channel extends along a second direction. The second direction forms an angle with the thickness direction of the cover plate.
[0005] Furthermore, the included angle is 90 degrees.
[0006] Furthermore, the cover plate includes an inner surface located on the acoustic cavity side and an outer surface disposed opposite to the inner surface, and the second channel is formed by recessing from the outer surface along the thickness direction of the cover plate.
[0007] Furthermore, the outer surface includes a bottom surface and a side surface located outside the bottom surface, the first channel penetrates the bottom surface, and the second channel penetrates the bottom surface and the side surface.
[0008] Furthermore, the second channel includes a first recessed groove and a second recessed groove communicating with the first recessed groove. The first recessed groove is located outside the first channel in the radial direction and is disposed around the first channel. The extension direction of the second recessed groove forms an angle with the thickness direction of the cover plate.
[0009] Furthermore, along the thickness direction of the cover plate, the depth of the second recessed groove is less than or equal to 1 mm.
[0010] Furthermore, the cover plate includes a first inner side and a second inner side, which are located on opposite sides of the second recessed groove, and the distance between the first inner side and the second inner side is less than or equal to 1.5 mm.

The second direction X2 forms an angle with the thickness direction X1 of the cover plate 3.
[0030] The setting of the second channel 312 enables the second channel 312 to balance the air pressure between the sound cavity 11 and the external space even when other components of the electronic device cover the first channel 311, saving the internal space of the electronic device and making the structure of the electronic device more compact. The cover plate 3 not only encloses the sound cavity 11 with the housing 1, but can also be used to fix other components of the electronic device, making the structure of the electronic device even more compact.
[0031] In some embodiments, the cover plate 3 and the housing 1 can be fixed by means of bonding, welding, snap-fastening, screw locking, etc.
[0032] In some embodiments, the cover plate 3 can be fixed to the middle frame of the electronic device.
