Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to an electronic equipment with dual sound cavities. Background Art

[0002] Existing electronic devices, such as mobile phones, require a certain amount of space within the phone's internal cavity for the phone's sound chamber, depending on actual design requirements. This sealed cavity is functionally divided into a front and rear sound chamber. Typically, the portion with the sound outlet serves as the front sound chamber, while the phone's speaker is placed in the rear sound chamber.

[0003] Since the upper half of the phone is mostly the motherboard area, and the front camera occupies the middle position on the top of the entire phone, the speaker unit inside the phone needs to be avoided, the layout space is tight, and the phone's sound cavity occupies a large space in the phone's internal structure, which is not conducive to the phone's structural design.

[0004] Due to the limitations of the phone's form factor, the space available for the phone's sound chamber is limited. Typically, the existing sound chamber volume is fixed. Even if the volume is reduced, it is difficult to meet the volume requirements of the speaker within the rear sound chamber. A phone with a sound chamber that is too small cannot meet the sound quality requirements.

[0005] Therefore existing technology still needs to be improved and improved. Utility Model Content

[0023] The present invention provides an electronic device with dual sound chambers. To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit the present invention.

[0024] Please also see Figures 1 to 4 The utility model provides an electronic device with dual sound cavities, including a front shell 1, a rear shell 2, a through hole 3, a screen module 4 and a speaker assembly; the screen module 4, the front shell 1 and the rear shell 2 are arranged in sequence from top to bottom; the speaker assembly is arranged between the front shell 1 and the rear shell 2, and the sealed cavity between the speaker assembly and the inner side of the adjacent side of the rear shell 2 forms a first rear sound cavity 5 located below, and the sealed cavity between the screen module 4 and the front shell 1 forms a second rear sound cavity 6 located above, and the first rear sound cavity 5 and the second rear sound cavity 6 are connected through the through hole 3 on the front shell 1 to form a sealed sound cavity of the entire electronic device.

[0025] The sealed cavity in the empty space between the front and rear shells and the corresponding components is used to form a corresponding rear sound cavity, and the two upper and lower rear sound cavities separated are connected to expand the volume of the sound cavity. This makes full use of the empty space inside the electronic device and meets the volume requirements of the sealed sound cavity, solving the problem that the existing mobile phone sound cavity occupies a large space in the internal structure of the mobile phone.

[0026] like Figure 1 、 Figure 2 and Figure 4 As shown, the electronic device also includes an existing motherboard 7, and the speaker assembly includes a speaker 8, an FPC (Flexible Printed Circuit) board 9 and a first sealing ring 10; the speaker 8 is electrically connected to the motherboard 7 through the FPC board 9, and the upper left corner of the rear shell 2 (with Figure 1 As an example, a first groove is provided, and the first sealing ring 10 is located in the first groove and is fixed (its bottom surface and surface are provided with adhesive and top adhesive respectively to achieve adhesive fixation) between the surface of the first groove and the bottom surface of the front shell 1. Figure 4 As shown ( Figure 4 It is the back structure after the front shell is flipped. Due to the flip, the speaker 8 part is turned to Figure 4 (See the upper right corner in the direction shown). Speaker 8 is located in the first groove and surrounded by first sealing ring 10. Pins on one end of FPC board 9 are electrically connected to corresponding pins on speaker 8. The other end of FPC board 9 extends out of the first groove (the portion intersecting with first sealing ring 10 is pressed by first sealing ring 10 and adhered to the surface of rear housing 2), and the pins on it are electrically connected to corresponding pins on mainboard 7.

[0027] The material of the front shell 1 and the rear shell 2 can be plastic or aluminum-titanium alloy. The side of the front shell 1 and the side of the rear shell 2 are a top-to-top structure. Figure 2 As shown, the two are placed overlappingly and the outer sides of the four sides of the front shell 1 are tightly against the inner sides of the corresponding sides of the rear shell 2. The dual-cavity structure is applicable to all electronic devices with speakers and two shells, such as mobile phones.

[0028] The mainboard 7 is a PCB (Printed Circuit Board), and the first sealing ring 10 is a compressed material with sealing properties, such as foam, silicone or rubber. The first sealing ring 10 seals the speaker 8 in the first groove on the rear housing 2. The position of the first groove utilizes the space between the mainboard 7 and the side of the rear housing, such as Figure 2 and Figure 4 As shown, the empty space between the speaker 8 and the first sealing ring 10 forms a sealed cavity, namely the first rear sound cavity 5. The empty space is fully utilized to form the rear sound cavity without occupying the space of the main board.

[0029] Since the front housing 1 is also provided with some second grooves for accommodating corresponding components, and the screen module 4 is flat, when the screen module 4 is fixed on the front housing 1, these second grooves will form a sealed cavity. This embodiment uses the sealed cavity located above the speaker 8 to expand the sound cavity structure (a sealed cavity that is far away and not connected is inconvenient to use). In order to circle a suitable sealed cavity and further enhance the sealing effect, the electronic device also includes a second sealing ring 11, as shown in FIG. Figure 3 As shown, the upper left corner of the front shell 1 (with Figure 1 A ring groove (one of the second grooves) is provided in the direction shown in the figure as an example, and the second sealing ring 11 is adhered between the surface of the ring groove and the bottom surface of the screen module 4.

[0030] The second sealing ring is made of the same material as the first sealing ring 10, and the size of the second sealing ring 11 is larger than the first sealing ring 10, preferably so as to enclose the first sealing ring 10 and the speaker 8. The sealed cavity between the screen module 4 and the front shell 1 is enclosed by the second sealing ring 11, so that the thickness of the layout space between the screen module 4 and the front shell 1 can be fully utilized to form the second rear sound cavity 6. Figure 2 As shown. The second rear sound cavity 6 is located directly above the first rear sound cavity 5. A through-hole 3 is provided through the front housing 1 at the location where the two rear sound cavities overlap, connecting the two rear sound cavities to form a sealed sound cavity for the entire electronic device. This expands the sound cavity and increases its volume to meet audio requirements. The first groove, the annular groove, and the bottom surface of the screen module are parallel to each other, ensuring the sealing effect of the sealed cavity and preventing air leakage due to unevenness, thereby ensuring the sound quality of the rear sound cavity.

[0031] Preferably, the electronic device further includes a receiver dustproof net 12 , a receiver hole is provided on the top side of the front shell 1 , and the receiver dustproof net 12 is arranged on the inner side of the receiver hole to achieve a dustproof effect.

[0032] To sum up, the electronic device with dual sound cavities of the present invention optimizes the structures of the front shell and the rear shell, utilizes the empty space between the front shell and the screen module, and the empty space between the main board 7 and the side of the rear shell, to form two upper and lower superimposed rear sound cavities, and then connects the two rear sound cavities through the through hole on the front shell, thereby increasing the volume of the rear sound cavity within a limited space, making full use of the internal structural space to meet the requirements of the speaker for the volume of the rear sound cavity, reducing the internal space occupied by the existing mobile phone sound cavity design, and solving the problem of the mobile phone sound cavity occupying a large internal structural space of the mobile phone in the prior art.

[0033] It should be understood that the application of the present invention is not limited to the above examples.
