The sealing member includes first sealing member 6, the one end of second support 4 with sound production subassembly 3 contacts, the other end of second support 4 passes through first sealing member 6 with first support 2 contacts, just first support 2 with form the back chamber between the second support 4, the second phonate hole 31 orientation of sound production subassembly 3 the back chamber, the sound production of second phonate hole 31 can be in the back intracavity is strengthened. The rear cover 1 is arranged on one side of the second bracket 4 far away from the first bracket 2.

The electronic equipment that this application embodiment provided sets up between first support 2 and second support 4 the sealing member, the sealing member can obstruct the sound air current that second phonate hole 31 sent is followed the back chamber flows, and it is right to have avoided the sound air current the vibration that back lid 1 produced has improved user's use and has experienced.

Optionally, the sealing member further includes a second sealing member 5, a first gap is left between the second bracket 4 and the rear cover 1, the second sealing member 5 is disposed between the rear cover 1 and the second bracket 4, that is, disposed in the first gap, and the second sealing member 5 may seal the first gap and may connect the second bracket 4 and the rear cover 1.

Specifically, on the basis of providing effective sound enhancement for the sound production assembly 3, in order to avoid excessive occupation of the internal space of the electronic device by the rear cavity, the rear cavity may adopt an open rear cavity. While an open back volume is typically formed by utilizing the space between the components within the electronic device. When the sound production assembly 3 produces sound, the sound airflow emitted from the second sound outlet 31 is transmitted to the rear cover 1 through the gaps between the devices, so that the rear cover 1 can vibrate obviously. The second sealing member 5 is disposed between the second bracket 4 and the rear cover 1, and referring to fig. 1 and fig. 2, specifically, the second sealing member 5 may be attached to an upper edge of a distal end of the second bracket 4, and the second sealing member 5 is connected to a lower surface of the rear cover 1, so that the sound airflow emitted from the second sound outlet 31 may be blocked from flowing out of the first gap, and vibration of the rear cover 1 caused by the sound airflow is avoided; in addition, the second sealing member 5 may provide a fulcrum for the rear cover 1, so as to stably support the rear cover 1 and further reduce the vibration of the rear cover 1.

Optionally, the rear cover 1 is a plain leather rear cover.

In particular, the skin rear cover is composed of plastic and leather, and has been widely used in rear covers of electronic devices because of its good hand feeling and aesthetic appearance.

Optionally, the sound generating assembly 3 is a speaker with a receiver function.

Specifically, the speaker with the telephone receiving function is generally a speaker with a relatively high power, and not only can play a role of normally sounding, but also can be used as a telephone receiving component of the electronic device. When the loudspeaker with the telephone receiving function works, continuous fluctuating airflow can be generated in the electronic equipment, and when the airflow flows to the rear cover 1, vibration can be generated on the rear cover 1. And the arrangement of the second sealing element 5 can avoid the direct impact of the airflow on the rear cover 1, and ensure the stable structure of the rear cover 1.

Optionally, the second seal 5 is foam cotton.

Specifically, the foam adhesive is manufactured by coating a solvent-based (or hot melt-type) pressure-sensitive adhesive on one or two surfaces of a substrate which is EVA (ethylene-vinyl acetate copolymer) or PE (polyethylene) foam as the substrate and then attaching release paper, and has the functions of sealing and shock absorption. The foam cotton rubber is arranged between the second support 4 and the rear cover 1, so that the second support 4 and the rear cover 1 can be effectively bonded, and the rear cover 1 can also have a good damping effect.

Alternatively, referring to fig. 2, a first reinforcing rib 21 facing the second bracket 4 is disposed on the first bracket 2, and the first sealing member 6 is disposed between the first reinforcing rib 21 and the second bracket 4.

Specifically, when a gap is left between the first bracket 2 and the second bracket 4, the sound airflow emitted from the second sound outlet hole 31 is transmitted to the rear cover 1 through the gap. The first reinforcing rib 21 and the first sealing element 6 are matched to effectively block the gap, so that the air flow is prevented from being transmitted to the rear cover 1 through the gap, the air flow moving space is reduced, and the vibration of the rear cover 1 caused by the air flow is avoided. In addition, because the length, width and thickness of the first sealing element 6 have certain specification limits, for example, when the length, width and size of the first sealing element 6 matches the gap, the thickness of the first sealing element 6 is not enough to seal the gap, and the length, width and size of the first reinforcing rib 21 can be flexibly set, so as to be closely matched with the first sealing element 6, thereby achieving the purpose of effectively sealing the gap.

Referring to fig. 2, the second holder 4 may be provided with a second rib 41 facing the first holder 2, and the first sealing member 6 may be provided between the second rib 41 and the first holder 2. The cooperation of the second reinforcing rib 41 and the first sealing member 6 can also effectively block the gap, and avoid the vibration brought to the rear cover 1 by the air flow.

In particular, the first seal 6 may be a sealing foam. The sealing foam can be made of foamed PU (polyurethane), EVA (ethylene vinyl acetate), PE (polyethylene), has good sound absorption and sound insulation effects, has good elasticity and lighter weight, and can effectively prevent air flow from being transmitted to the rear cover 1 through the gap.

Optionally, referring to fig. 1 and 2, the electronic device further includes a main board 7, and the main board 7 is disposed in the rear cavity and connected to the first bracket 2.

Specifically, the main board 7 may carry a plurality of electronic components, and the electronic components with multiple functions are electrically connected with each other to form a core module or a control center with functions required by the electronic device. The sound production subassembly 3 can with the mainboard 7 electricity is connected, through mainboard 7 comes nimble control the sound production effect of sound production subassembly 3.

Specifically, the first bracket 2 may be a motherboard upper frame or a middle frame, the second bracket 4 may be a motherboard bracket, and the first bracket 2 and the second bracket 4 may support and fix the motherboard 7, thereby ensuring stable performance of the function of the motherboard 7. In addition, an FPC (flexible circuit board) 71 may be further disposed on the main board 7, and since the first sealing member 6 has better elasticity, the FPC 71 is pressed between the first sealing member 6 and the first bracket 2 or the second bracket 4 and then extends out of the rear cavity, so as to complete flexible connection of the FPC 71.

Optionally, referring to fig. 1 and 2, a screen 8 is disposed on a side of the first support 2 away from the second support 4. The screen 8 can be specifically bonded with the first support 2, the first support 2 provides stable support for the screen 8, the screen 8 ensures information interaction between a user and the electronic device, and use experience of the user is improved.
