When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0027] Please refer to Figures 1 to 3 , the embodiments of the present application provide a mobile phone, which includes a front frame 110, a back plate 120, and a speaker module 200. Of course, the mobile phone also includes other conventional functional components such as a battery, a main control circuit board, a touch screen, and a camera. Since they are not related to the inventive points, they will not be elaborated here. The mobile phone can be a three-proof mobile phone with a relatively large battery and a relatively large volume.

[0028] The front frame 110 can be integrally injection-molded by a metal rib plate and a plastic housing. The back plate 120 is matched with the front frame 110 to form a cavity, and components such as a battery and a main control circuit board are arranged in the cavity. The back plate 120 is provided with a sound outlet hole 121, and the sound outlet hole 121 can be an elongated groove and is arranged near the tail end on the back of the mobile phone.

[0029] The speaker module 200 is arranged in the cavity and fixed to the front frame 110 and / or the back plate 120. In the embodiment of the present application, the speaker module 200 can be fixed to the front frame 110 by 4 screws.

[0030] Specifically, the speaker module 200 includes a front shell 210, a rear cover 220, and a speaker 230. The front shell 210 is respectively provided with a lateral assembly opening 211 and a top sound outlet hole 212 on two mutually perpendicular surface sides. The rear cover 220 covers the lateral assembly opening 211 to cooperate with the front shell 210 to form a sound cavity. The speaker 230 is assembled in the sound cavity in an upright posture and divides the sound cavity into a front sound cavity and a rear sound cavity. The top sound outlet hole 212 is communicated with the front sound cavity, and the sound emitted by the speaker 230 is transmitted out through the top sound outlet hole 212 and the sound outlet hole 121 in sequence after a 90-degree turn. That is to say, the speaker 230 is perpendicular to the screen of the mobile phone and faces the bottom end of the mobile phone, and the sound emitted by the speaker 230 is transmitted out from the back plate 120 of the mobile phone after a 90-degree turn.

[0031] Wherein, taking the three-dimensional structure of the mobile phone as a reference, the mobile phone includes a front surface, a back surface, a pair of long side surfaces, and a pair of short side surfaces. In the present application, the two mutually perpendicular surface sides respectively correspond to the short side surface of the mobile phone and the back surface of the mobile phone, that is, the front shell 210 of the speaker module 200 is provided with a lateral assembly opening 211 corresponding to the short side surface of the mobile phone and a top sound outlet hole 212 corresponding to the back surface of the mobile phone.

[0032] The front shell 210 can be provided with a stepped cavity for assembling the speaker 230, and the speaker 230 and the front shell can be adhesively fixed by glue. The rear cover 220 and the front shell 210 can be fixedly connected by glue or ultrasonic welding.

[0033] The front shell 210 is provided with a sealing groove around the top sound outlet hole 212, and the speaker module 200 further includes a sealing ring 250, and the sealing ring 250 is matched and arranged in the sealing groove.

[0034] In the embodiments of the present application, the sealing groove includes an annular groove portion 241 and a positioning portion 242, and the sealing ring 250 includes an annular ring portion 251 and a positioning block 252. The annular ring portion 251 matches the annular groove portion 241, and the positioning block 252 matches the positioning portion 242. The matching of the positioning block 252 and the positioning portion 242 can achieve a good anti-misassembly effect. Further, a ring groove is further provided on the bottom surface of the sealing ring 250. Correspondingly, the cross-section of the sealing ring 250 is an inverted "concave" shape. The side of the sealing ring 250 with the ring groove is buckled towards the sealing groove. The back plate 120 can be provided with a circle of pressing ribs (not shown in the figure) corresponding to the sealing ring 250. When the back plate 120 and the front frame 110 are tightly fitted by screws, the pressing ribs press on the surface side of the sealing ring 250 without the ring groove. Since the bottom surface of the sealing ring 250 is provided with a ring groove and the back plate 120 is provided with a circle of pressing ribs, the sealing ring 250 can have a large deformation during assembly and form a good waterproof sealing effect.

[0035] In the embodiments of the present application, a ventilation hole 223 is provided on one side edge of the rear cover 220 away from the speaker 230.

[0036] The rear cover 220 can be an integral plastic cover plate, or the rear cover 220 includes a plastic cover plate 221 and a metal cover plate 222 embedded in the plastic cover plate 221, and the ventilation hole 223 is opened on the plastic cover plate 221. When the rear cover 220 is provided with the metal cover plate 222, the metal cover plate 222 can play the roles of heat conduction, grounding, and enhancing strength and reducing thickness.

[0037] As Figure 3 shown, the front shell 210 is provided with a plurality of stepped holes 213. The number of the stepped holes 213 can be 4. The stepped holes 213 are used to receive the screws 215 for assembly to be fixed to the front frame 110.

[0038] The front shell 210 and the rear cover 220 are further provided with avoidance grooves 214 for avoiding the Type-C interface of the mobile phone.

[0039] Please continue to refer to Figure 2 and Figure 3 , the embodiments of the present application further provide a speaker module 200. The speaker module 200 includes a front shell 210, a rear cover 220, and a speaker 230. The front shell 210 is respectively provided with a lateral assembly opening 211 and a top sound outlet hole 212 on two surface sides perpendicular to each other. The rear cover 220 covers the lateral assembly opening 211 to cooperate with the front shell 210 to form a sound cavity. The speaker 230 is erected and assembled in the sound cavity in a posture parallel to the rear cover 220 and divides the sound cavity into a front sound cavity and a rear sound cavity. The sound emitted by the speaker 230 is transmitted out from the top sound outlet hole 212 after a 90-degree turn.

[0040] The front shell 210 is provided with a sealing groove around the top sound outlet hole 212. The speaker module 200 further includes a sealing ring 250 which is fitted in the sealing groove. The rear cover 220 includes a plastic cover plate 221 and a metal cover plate 222 embedded in the plastic cover plate 221, and the plastic cover plate 221 is provided with ventilation holes 223.

[0041] Further, extension arms 260 are provided on both sides of the front shell 210, and conductive pins 261 are provided at the free ends of the extension arms 260. The conductive pins 261 can be used to electrically ground the main control circuit board of the mobile phone to the mobile phone shell.

[0042] In summary, it is easy for those skilled in the art to understand that for the mobile phone and its speaker module 200 provided by the present utility model, by vertically erecting and assembling the speaker 230 in the sound cavity in a posture perpendicular to the mobile phone screen, the space occupied in the length direction of the mobile phone is reduced, the layout of the structural components in the mobile phone is optimized, and the product structure is made more compact.

[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
