As shown in fig. 2 and 3, a second sealing member 62 is disposed between the battery assembly 3 and the middle frame assembly 2, and the second sealing member 62 is used for sealing a gap between the battery assembly 3 and the middle frame assembly 2, so as to prevent the sound of the electroacoustic assembly 4 from leaking from the gap between the battery assembly 3 and the middle frame assembly 2, thereby improving the sealing performance of the rear cavity 100b, effectively preventing the acoustic short circuit of the low frequency in the electroacoustic assembly 4, and for example, preventing the acoustic short circuit of the medium frequency when the electroacoustic assembly 4 is used as a speaker device.
Wherein the second sealing member 62 is located outside the cavity 100a, the second sealing member 62 is disposed so as not to occupy the space of the cavity 100a, i.e., the second sealing member 62 is disposed so as not to reduce the space of the cavity 100a, thereby further ensuring the volume of the back cavity 100b of the electroacoustic component 4.

In the example of fig. 2 and 3, the second sealing member 62 may be an adhesive tape, such as an elastic adhesive tape, to effectively seal the gap between the battery assembly 3 and the middle frame assembly 2; the second seal 62 may be formed in a generally U-shaped configuration. Of course, the second sealing member 62 may be other material pieces, and is not limited thereto.
It is understood that, in order to ensure the sealing performance of the cavity 100a, the electronic device 100 may further include a third sealing member, which may be disposed between the battery cover 1 and the middle frame assembly 2, for example, the third sealing member may be a double-sided tape; but is not limited thereto.

As shown in FIGS. 1-3, the volume V of the cavity 100a satisfies V ≧ 2cc, for example, the volume V of the cavity 100a can be 2cc, 3cc, or 5cc, etc., and compared with the related art, the volume of the conventional Box back cavity 100b formed by arranging the whole Box or half Box is substantially 0.8cc, the volume of the back cavity 100b of the electroacoustic component 4 in the present application can reach 2cc, even can exceed 2cc, thereby effectively increasing the volume of the back cavity 100b of the electroacoustic component 4 and enhancing the low-frequency effect of the electronic device 100.
