[0021] This utility model provides a smartphone with a dustproof and waterproof earpiece. To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the following detailed description, with reference to the accompanying drawings and embodiments, further illustrates the utility model. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this utility model.

[0022] Please also refer to Figures 1 to 6 This utility model provides a smartphone with a dustproof and waterproof earpiece. The front shell assembly 1 of the smartphone has a sound cavity 2, and a speaker outlet 3 is provided on one side of the sound cavity 2. The two-in-one earpiece speaker 4 is fixed in the sound cavity by a dustproof and waterproof component. The dustproof and waterproof component is used to isolate water and dust at the speaker outlet 3 and to provide waterproof and dustproof protection for the earpiece speaker 4. This solves the problem of poor waterproof and dustproof effect of existing two-in-one earpiece speakers.

[0023] It should be understood that the smartphone also includes existing structures such as the mid-shell assembly, rear shell assembly, and touchscreen, and there are other structural components on the front shell assembly. This section only describes the structure related to the earpiece; other existing structures will not be detailed.

[0024] like Figure 2 As shown, the dustproof and waterproof components include a dustproof mesh 5 with self-adhesive backing, a handset steel plate 6, and a waterproof foam rubber ring 7. The dustproof mesh 5 is adhered to the plane 8 at the bottom of the sound cavity 2. The handset steel plate 6 covers the entire sound cavity. The edge of the handset steel plate 6 is adhered to the first step surface 10 of the outer ring of the plane with waterproof adhesive 9. The main body of the handset steel plate 6 is adhered to the adhesive 18 of the dustproof mesh 5. One side of the waterproof foam rubber ring 7 is adhered to the second step surface 11 of the sound cavity 2, and the other side of the waterproof foam rubber ring 7 is adhered to the handset speaker component 4.

[0025] by Figure 3 Taking the direction shown as an example, the upper left part of the plane 8 at the bottom of the sound cavity 2 is provided with a first concave surface 13. The first concave surface 13 occupies nearly 1 / 4 of the area of ​​the plane 8. The upper left part of the first concave surface 13 is further concave to form a long strip-shaped second concave surface 14, and the side of the second concave surface 14 is connected to the speaker outlet hole 3. By continuously concave in this way, gaps are left so that sound can be transmitted.

[0026] The first stepped surface 10, surrounding the plane 8, is the bonding surface of the earpiece steel sheet 6, and is 1-2mm higher than the plane 8. This allows for a certain gap when bonding the earpiece steel sheet 6. Furthermore, to facilitate sound propagation and prevent the earpiece steel sheet 6 from completely blocking the sound cavity, there is no first stepped surface 10 above the second concave surface 14. Therefore, the first stepped surface 10 is a notched ring with a notch in the upper left part. Correspondingly, as... Figure 4 As shown, the shape of the waterproof adhesive 9 is adapted to the first stepped surface 10.

[0027] The second stepped surface 11 of the acoustic cavity 2 is 1-2 mm higher than the first stepped surface 10, and a raised baffle 15 for framing the waterproof foam rubber ring 7 is provided at the edge of the second stepped surface 11. Since the waterproof foam rubber ring 7 has a certain thickness, the position of the baffle 15 is related to the components surrounding the acoustic cavity 2 and the frame of the front shell assembly, such as... Figure 3 As shown, baffles 15 are provided on the upper side, the upper part of the left and right sides, and the middle of the lower side of the second step surface 11. This can prevent the waterproof foam rubber ring 7 from shifting during use and affecting other adjacent devices.

[0028] like Figure 4 As shown, the dustproof net 5 includes four sub-nets 16 and an adhesive backing 18 with four perforated slots. One sub-net 16 is fixed in one perforated slot. The four sub-nets 16 are used to isolate dust at the speaker outlet 3 and can also transmit sound. The waterproof adhesive backing 9 and the adhesive backing 18 are on the same plane and are both used to bond the earpiece steel plate 6. The waterproof adhesive backing 9 mainly bonds the edge of the earpiece steel plate 6, while the adhesive backing 18 mainly bonds the main body of the earpiece steel plate 6. Except for the perforated slots for installing the sub-nets 16, the rest of the adhesive backing 18 is an adhesive surface, which is to maximize the adhesive surface with the earpiece steel plate 6 and, together with the waterproof adhesive backing 9, ensure the firmness of the earpiece steel plate 6.

[0029] like Figure 5 As shown, the earpiece steel sheet 6 has four square holes with positions and sizes matching the sub-net 16, allowing the sub-net 16 to be exposed for sound transmission. The edge of the earpiece steel sheet 6 is bent upwards and then horizontally, forming a vertical bend and a 2mm wide rim 12. The rim 12 overlaps the second stepped surface 11, so that the earpiece steel sheet 6 completely covers the entire sound cavity. Through the sealing and isolation of the earpiece steel sheet 6, dust and moisture are completely prevented from entering the smartphone through the sound cavity, further achieving a waterproof and dustproof effect. Furthermore, the high hardness of the earpiece steel sheet 6 also provides support and protection for the earpiece speaker component 4.

[0030] by Figure 6 Taking the direction shown as an example, the waterproof foam rubber ring 7 has double-sided adhesive. One side (bottom surface) is adhered to the second step surface 11 of the sound cavity 2, and blocks the buckle 12 of the earpiece steel plate 6. The other side (top surface) of the waterproof foam rubber ring 7 is adhered to the outer ring of the earpiece speaker component 4, such as... Figure 7 As shown, the assembled earpiece speaker 4 is further waterproofed by the waterproof foam rubber ring 7.

[0031] Preferably, a marking strip 17 can also be provided on the steel plate 6 of the earpiece to identify the direction and prevent mistaken identity.

[0032] In summary, the dustproof and waterproof smartphone earpiece provided by this utility model uses a dustproof mesh to isolate dust and bond the earpiece steel sheet. Combined with the sealing, isolation, and support of the earpiece steel sheet, it completely prevents dust and moisture from entering the smartphone through the sound cavity. Furthermore, the waterproof effect of the waterproof foam rubber ring further protects the earpiece speaker component from water damage.

[0033] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
