As shown in fig. 1 to 3 and 8, in an embodiment, the mobile terminal is a mobile phone, and includes a display screen 400, a middle frame 500, a rear case 600, a main housing 100 and an audio cavity 200. The display screen 400, the middle frame 500 and the rear shell 600 form an external structure of the mobile phone, the main shell 100 is located between the display screen 400 and the rear shell 600, and the peripheral surface of the main shell 100 is surrounded by the middle frame 500. The display screen 400 is the front side of the mobile phone, and the rear case 600 is the back side of the mobile phone. As shown in fig. 4 and 7, the sound chamber 200 is fixed to the lower right corner of the main housing 100 when viewed from the back of the cellular phone.

As shown in fig. 4, 7 and 8, in an embodiment, a support 300 for supporting the sound cavity 200 is further provided on the mobile phone. When viewed from the back of the mobile phone, a through hole 110 is formed in the lower right corner of the main housing 100, and the shape of the inner wall of the through hole 110 is the same as the outer peripheral shape of the bracket 300. The holder 300 is installed in the through-hole 110 to support and fix the sound chamber 200 so as not to be exposed from the bottom end of the through-hole 110, which is the end of the through-hole 110 remote from the rear case 600.

When the support 300 and the main housing 100 are integrally designed, because the area of the support 300 is large, when the main housing 100 is made of plastic or alloy, if the support 300 is processed to be thin, the material is easy to be starved, so the thickness of the support 300 of the main housing 100 with the existing integral design is 0.4mm at the thinnest. When the support frame 300 and the main housing 100 are designed to be separated, the support frame 300 is separately manufactured, so that the support frame 300 can be made as thin as possible. In this embodiment, the bracket 300 is separately processed, and the thickness is less than 0.40 mm. In a mobile phone, under the condition that the internal space of the mobile phone enclosed by the display screen 400, the middle frame 500 and the rear shell 600 is not changed, the thinner the support 300 is, the more the thickness of the sound cavity 200 can be increased, and the shorter the sound cavity 200 can be in the length direction of the mobile phone. The space saved by the sound cavity 200 in the length direction of the mobile phone can be used for increasing the size of a battery and prolonging the endurance time of the mobile phone; or, the space saved by the sound cavity 200 in the length direction of the mobile phone can be used for reducing the length of the whole mobile phone and increasing the appearance competitiveness of the mobile phone.

As shown in fig. 5 to 7, in an embodiment, the mobile phone further includes a blocking portion 120 extending from the main housing 100 into the through hole 110. The blocking part 120 is located at the bottom end of the through hole 110, one side of the blocking part 120 close to the display screen 400 is flush with the main casing 100, one side of the blocking part 120 far away from the display screen 400 is located in the through hole 110, the distance between the two sides is the thickness of the blocking part 120, and the thickness of the blocking part 120 is smaller than the depth of the through hole 110. The width of the main housing 100 extending into the through hole 110 is uniform, that is, the blocking portion 120 is a ring shape with uniform width, the shape of the inner ring shape is the same as that of the through hole 110, and the size of the inner ring shape is smaller than that of the through hole 110. The blocking portion 120 serves to support the supporter 300 to prevent the supporter 300 from falling out of the bottom of the through-hole 110.

As shown in fig. 5-7, in one embodiment, the bracket 300 includes a sheet structure 320 and a protrusion 310. The sheet structure 320 is an irregular polygonal structure with uniform thickness, and the outer circumference of the sheet structure 320 has the same shape as the inner wall of the through hole 110. The sheet structure 320 includes a sinking platform 321 and a side 322, and a height difference exists between the sinking platform 321 and the side 322. The height difference between the top of the platform 321 and the top of the side 322 makes the platform 321 form a concave bearing space for supporting the sound cavity 200. The upper surface of the sinking platform 321 is in contact with the lower surface of the sound cavity 200, and the convex-concave direction of the upper surface of the sinking platform 321 is opposite to that of the lower surface of the sound cavity 200, that is, in an ideal state, the upper surface of the sinking platform 321 is in seamless fit with the lower surface of the sound cavity 200, and the convex-concave structure of the upper surface of the sinking platform 321 plays a role in positioning the sound cavity 200. The side 322 encloses at least a portion of the acoustic chamber 200 and prevents the acoustic chamber 200 from moving in a plane parallel to the display screen 400. The protrusion 310 is a bar-shaped block with a square cross section, and is embedded in the edge of the side edge 322, so that the outer side surface of the protrusion 310 is flush with the outer peripheral surface of the side edge 322. One end of the protrusion 310 is flush with the lower surface of the side 322, and the other end protrudes from the upper surface of the side 322, and the protrusion 310 is perpendicular to the side 322.

The height difference between the lower surface of the sinking platform 321 and the bottom of the side 322 enables the bottom of the sinking platform 321 to be flush with the bottom of the blocking part 120 after the side 322 is mounted on the blocking part 120. The width of the side edge 322 is the same as the width of the blocking part 120, or the width of the side edge 322 is slightly smaller than the width of the blocking part 120, so that after the side edge 322 is mounted on the blocking part 120, the position of the height difference between the side edge 322 and the sinking platform 321 is in butt joint with the blocking part 120.

As shown in fig. 5 to 7, in an embodiment, the main housing 100 further includes a fastening position 111 cooperating with the protrusion 310. The buckling position 111 is a strip-shaped block located on the inner wall of the through hole 110, and comprises a vertical surface 1111 perpendicular to the inner wall of the through hole 110 and an inclined surface 1112 forming an acute angle with the inner wall of the through hole 110, namely, the cross section of the buckling position 111 is a right triangle, a right angle surface is located on the inner wall of the through hole 110, and the other right angle surface, namely, the vertical surface 1111 faces the bottom end of the through hole 110 and is parallel to the blocking part 120 and is the lower surface of the buckling position 111. The distance between the lower surface of the fastening position 111 and the stop part 120 is equal to the height of the protrusion 310, so that the fastening position 111 prevents the bracket 300 from moving in the assembled state.

When the bracket 300 is required to be assembled in the through hole 110, the bracket 300 is put into the through hole 110, and the buckling position 111 interferes with the outer side surface of the protrusion 310. Pressing force is applied to the bracket 300, so that the protrusion 310 elastically deforms and retracts to pass through the buckling position 111, and the bracket 300 continues to move towards the bottom end of the through hole 110 until the side edge 322 is overlapped on the blocking portion 120. At this time, the protrusion 310 is elastically restored to a state perpendicular to the side 322, and the top of the protrusion 310 is located below the lower surface of the fastening position 111, so that the bracket 300 is fixed.

As shown in fig. 5 to 7, in an embodiment, at least one side 322 is not provided with the protrusion 310, and the side 322 is provided with the extension block 323. When the bracket 300 needs to be assembled in the through hole 110, the bracket 300 is slightly inclined and placed in the through hole 110, so that the extension block 323 is inserted between the buckling position 111 and the blocking part 120 at the corresponding position, interference is generated between the buckling position 111 at other positions and the outer side surface of the protrusion 310, the bracket 300 is pressed, the protrusion 310 elastically deforms and retracts to pass over the buckling position 111, and the bracket 300 continues to move towards the bottom end of the through hole 110 until the side edge 322 is lapped on the blocking part 120. At this time, the protrusion 310 is elastically restored to a state perpendicular to the side 322, and the top of the protrusion 310 is located below the lower surface of the fastening position 111, so that the bracket 300 is fixed.

In one embodiment, the bracket 300 is integrally formed by a metal plastic forming process. The bracket 300 is made of a material with a relatively soft material, such as stainless steel, phosphor copper, red copper, beryllium copper, nickel copper alloy, and the like. The support 300 may be formed by thin metal sheet metal plastic forming, specifically, stainless steel with a thickness of 0.15-0.30mm may be processed by metal plastic forming processes such as forging or stamping, the adopted mold is an upper and lower mold closing structure, and the structure of the male mold is the same as the shape of the sound cavity 200.

In one embodiment, the main housing 100 is made of plastic and is formed by injection molding. In other embodiments, the main housing 100 is made of an alloy, and can be formed by casting or metal injection molding. The above-described molding methods are all suitable for manufacturing products with complex shapes, and the precision of the manufactured main housing 100 is high.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
