Abstract: An electronic device may include a mobile phone, a tablet computer, a handheld computer, a walkie-talkie, a POS machine, an event data recorder, a wearable device, a virtual reality device, or in-vehicle original equipment or another terminal product with a loudspeaker. An inner wall of a mounting cavity for mounting a loudspeaker and the loudspeaker are respectively provided with mating surfaces that adapt to each other. In the two mating surfaces, one is provided with a flexible sealing member and a limiting structure, and the other is provided with a rigid sealing member. When the loudspeaker is mounted, the rigid sealing member can move relative to the flexible sealing member along a first direction, until the rigid sealing member is mated with the flexible sealing member. The limiting structure can restrict the flexible sealing member from moving.
