[0018] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1As shown, the electronic device capable of balancing the internal air pressure provided in the present embodiment may be a mobile phone, a tablet, etc., and mainly includes an electronic device housing 10 and a sound-emitting body 20 arranged in the electronic device housing 10, wherein a first cavity 11 is arranged in the electronic device housing 10, the sound-emitting body 20 includes a speaker housing 21 and a speaker unit 22 arranged in the speaker housing 21, a second cavity 23 is arranged in the speaker housing 21, a plurality of balancing holes 24 are arranged on the speaker housing 21, and the balancing holes 24 are used to connect the first cavity 11 and the second cavity 23, and a waterproof breathable membrane 31 is arranged on the speaker housing 21, and the waterproof breathable membrane 31 is used to cover the balancing holes 24.
