[0047] Please refer to Figures 1 to 4 , in an embodiment of the present invention, the security camera 100 includes a main body component 10 and a speaker component 30. The main body component 10 includes a first housing 11, a camera unit 13, and a battery 15. The first housing 11 forms an installation groove 11a. The camera unit 13 and the battery 15 are arranged side by side in the installation groove 11a. A first connection portion 1131 is provided at the outer edge of the opening of the installation groove 11a. The speaker component 30 includes a second housing 31 and a speaker unit 33 provided in the second housing 31. A second connection portion 3131 is provided on the inner side of the end of the second housing 31 facing the first housing 11. The first housing 11 and the second housing 31 are connected by the engagement of the first connection portion 1131 and the second connection portion 3131.

[0048] In this embodiment, the security camera 100 can be applied to indoor, roadside and other environments to monitor the indoor or outdoor environment or people, so as to detect abnormalities in time and control them to ensure safety. Of course, the security camera 100 can also be applied to other environments and can be installed according to needs.

[0049] Here, the security camera 100 includes a main body component 10 and a speaker component 30. The main body component 10 is the main part for realizing camera monitoring. A camera unit 13 is arranged therein, and the external environment can be monitored through the first housing 11. When the security camera 100 needs to be installed at a certain position, it can be fixed through the first housing 11. For example, one end of the first housing 11 away from the speaker component 30 can be fixed to a wall or a pole, etc., or the circumferential side of the first housing 11 can be directly fixed, which is not limited herein. The material of the first housing 11 can be plastic, wooden, metal or ceramic, etc., which is not limited herein. Optionally, when the material is plastic, on the one hand, it is convenient for processing and forming, on the other hand, the cost is low and the insulation performance is good; or when the material is metal, the structural strength is high and the corrosion resistance is good, and an insulating paint can be coated on the surface, which can significantly improve the use performance of the security camera 100. The first housing 11 is formed with an installation groove 11a, and the opening of the installation groove 11a can be circular, square or polygonal, etc., which is not limited herein.

[0050] It can be understood that the security camera 100 of this embodiment comes with a battery 15 to provide electrical energy for the camera unit 13 and the speaker component 30, and can be applied in places without power supply, thereby improving adaptability and setting flexibility. The camera unit 13 and the battery 15 are arranged side by side in the installation groove 11a, and the battery 15 is preferably arranged near the notch of the installation groove 11a for convenient disassembly and assembly. Here, one, two or more than two batteries 15 can be set according to actual power supply requirements.

[0051] The speaker component 30 includes a second housing 31 and a speaker unit 33 arranged in the second housing 31. The speaker unit 33 here can be a conical speaker or a flat speaker, and its acoustic performance and shape are not limited herein and can be set according to actual needs as long as electro-acoustic conversion and sound generation can be realized. The material of the second housing 31 can be the same as or different from that of the first housing 11. For example, it can be plastic or metal, etc., to provide protection and an installation foundation. The shape of the second housing 31 is a cone here, and a sound emitting hole 31d is opened at one end away from the main body component 10, so that the sound flows out from the sound emitting hole 31d, and one end facing the main body component 10 is detachably connected to the first housing 11, and the shape of the first housing 11 is a cylinder, so as to match the second housing 31. Of course, in other embodiments, the cross-sectional shape of the second housing 31 can also be square or polygonal, etc.

[0052] Optionally, a first connection portion 1131 is provided at the end of the first housing 11, and a second connection portion 3131 is provided at the notch of the installation groove 11a. The first connection portion 1131 and the second connection portion 3131 are snap-connected, so as to assemble the main body assembly 10 and the speaker assembly 30. The snap connection here can be a snap structure, a hook structure or other structures that can be clamped and fixed after docking, and is not limited here. After the first housing 11 is connected to the second housing 31, the speaker assembly 30 can abut against the battery 15 and other structures in the installation groove 11a, so as to complete the assembly of the overall structure. When disassembling, only the snap structure needs to be released to realize the common disassembly of the speaker assembly 30 and the battery 15.

[0053] In the security camera 100 of the technical solution of the present invention, the main body assembly 10 and the speaker assembly 30 are set to be detachably connected. Specifically, the first housing 11 and the second housing 31 are connected by a snap connection method, so that the assembly and disassembly are more convenient, no tools are required, and there is no need to disassemble the speaker assembly 30 after removing the main body assembly 10, which simplifies the disassembly and assembly structure, improves the disassembly and assembly efficiency, and realizes the quick disassembly of the speaker assembly 30. At the same time, after the speaker assembly 30 is removed, the notch of the installation groove 11a can be exposed, which can facilitate the removal of the battery 15 for charging. Therefore, in the structure of the security camera 100 without an external power supply, the disassembly and assembly process can be further saved, and the convenience can be improved. The security camera 100 with this structure sets the main body assembly 10 and the speaker assembly 30 as relatively independent modules, so that the speaker assembly 30 can be replaced at any time according to needs to realize different personalized requirements. At the same time, combined with the cavity formed after the first housing 11 and the second housing 31 are connected to accommodate the battery 15, and the quick disassembly method, the disassembly and assembly convenience and the charging convenience are greatly improved, and the airtightness of the battery 15 is ensured while the disassembly and assembly are convenient.

[0054] Please combine Figure 3 and Figure 4 In one embodiment, one of the first connection portion 1131 and the second connection portion 3131 is a rotary female buckle, and the other is a rotary male buckle. The first housing 11 rotates relative to the second housing 31 so that the rotary male buckle is snapped into the rotary female buckle.

[0055] To further improve convenience, in this embodiment, the first housing 11 and the second housing 31 are arranged in a rotatable snap - fit connection manner. That is, a rotatable female buckle is provided on one of them, and a rotatable male buckle is provided on the other. Specifically, an installation plate 115 protrudes from the opening edge of the installation groove 11a. The installation plate 115 is annularly arranged on the opening edge of the installation groove 11a. The rotatable female buckle is arranged on the outer surface of the installation plate 115. The rotatable female buckle has an inverted "7" - shaped structure, and one side in the circumferential direction has an opening 1131a. The shape of the rotatable male buckle is the same as that of the rotatable female buckle, but the inverted direction is opposite. In this way, after docking the first housing 11 and the second housing 31, the rotatable male buckle is inserted into the opening 1131a. After rotation, the rotatable male buckle is snapped into the closed end of the rotatable female buckle to complete the connection, which is simple and convenient and saves manpower. When disassembling, after rotating in the reverse direction, the snap - fit can be released, and then the rotatable male buckle can be pulled out from the opening 1131a, truly realizing quick disassembly and effectively improving the disassembly and assembly efficiency.

[0056] Here, the number of the first connection part 1131 and the second connection part 3131 can be set to multiple, that is, multiple rotatable male buckles and multiple rotatable female buckles are provided, and the numbers are the same. For example, two, three or more than three. The multiple rotatable female buckles are spaced apart from each other on the opening edge of the installation groove 11a, and the multiple rotatable female buckles are arranged in one - to - one correspondence with the rotatable male buckles. Thus, when rotatably snap - fitting, the connection structure between the first housing 11 and the second housing 31 can be increased, and the connection stability can be improved. Of course, here three rotatable female buckles are provided and evenly spaced in the circumferential direction on the installation plate 115, and the rotatable male buckle is adapted to it, so as to play a role of more uniform force and ensure the connection stability.

[0057] Please continue to refer to Figure 3 and Figure 4 , in an embodiment, a positioning convex part 3133 is provided on one of the outer edge of the opening of the installation groove 11a and the end of the second housing 31, and a positioning concave part 1133 is provided on the other. The first housing 11 and the second housing 31 are rotatably snap - fitted after being inserted and positioned by the positioning convex part 3133 and the positioning concave part 1133.

[0058] In this embodiment, in order to achieve docking of the first shell 11 and the second shell 31, a positioning protrusion 3133 is provided on the outer edge of the opening of the mounting groove 11a, that is, the outer surface of the mounting plate 115 and the end of the second shell 31, and a positioning recess 1133 is provided on the other. For example, the outer surface of the mounting plate 115 is provided with a positioning protrusion 3133, and the end of the second shell 31 is provided with a positioning recess 1133, or the end of the second shell 31 is provided with a positioning protrusion 3133, and the end of the first shell 11 is provided with a positioning recess 1133. The positioning protrusion 3133 can be a columnar or block-shaped, etc., and the positioning recess 1133 can be a notch, a groove body or a hole body, etc., which is not limited here. When the first shell 11 and the second shell 31 are docked, the positioning is achieved by the cooperation of the positioning protrusion 3133 and the positioning recess 1133, and then the rotation is engaged to improve the accuracy, and at the same time, the anti-fool effect can be achieved.

[0059] Of course, the positioning protrusion 3133 and the positioning recess 1133 can be optionally provided in plurality, and the plurality of positioning recesses 1133 are spaced apart and distributed on the opening edge of the mounting groove 11a, so as to improve the positioning effect. Here, in order to improve the structural strength, two positioning protrusions 3133 and two positioning recesses 1133 are provided, and they are not centrally symmetrical with respect to the center of the first shell 11, so as to achieve an anti-foolproof effect.

[0060] Please refer again Figure 3 and Figure 4 In order to further enhance the assembly feel, in one embodiment, one of the outer edge of the opening of the mounting groove 11a and the end of the second shell 31 is provided with a snap-fitting protrusion 1135, and the other is provided with two spaced snap-fitting ribs 3135, and a snap-fitting groove 3135a is formed between the two snap-fitting ribs 3135. When the first shell 11 and the second shell 31 are rotatably engaged, the snap-fitting protrusion 1135 slides into the snap-fitting groove 3135a along one of the snap-fitting ribs 3135.

[0061] In this embodiment, the positioning protrusion is strip-shaped and extends along the axis direction of the first housing 11. The shapes of the two engaging ribs 3135 are similar to or the same as that of the positioning protrusion, and are spaced apart by a certain distance, so that the space between the two forms an engaging groove 3135a. Of course, when the first housing 11 and the second housing 31 are butted and rotated, the positioning protrusion presses against the engaging rib 3135 and slides into the engaging groove 3135a, forming a "click" feeling of being engaged in place, thus prompting from the tactile aspect that the rotation is in place, and can also prevent the rotating male buckle from disengaging from the rotating female buckle in the circumferential direction, effectively improving the stability of the circumferential rotation engagement between the two. Here, the heights of both the positioning protrusion and the engaging rib 3135 protruding are relatively small, so as to facilitate the positioning protrusion to cross the engaging rib 3135 and enter the engaging groove 3135a. At the same time, the two engaging ribs 3135 can be set as an integral structure, that is, in a wave crest and wave trough shape, with the engaging groove 3135a in the middle in the shape of a wave trough and the engaging ribs 3135 on both sides in the shape of wave crests, thus improving the engaging effect.

[0062] The positioning protrusion here is arranged on the mounting plate 115 of the first housing 11 and can be arranged close to the rotating female buckle. Correspondingly, the engaging rib 3135 is arranged at the end of the second housing 31. Of course, in other embodiments, multiple positioning protrusions and corresponding engaging grooves 3135a can also be arranged.

[0063] Please refer to Figures 3 to 5 , in order to further improve the installation stability, in one embodiment, a fixing nut 12 is provided on the end face of the first housing 11 facing the second housing 31. The second housing 31 is provided with a through hole 31a. The second housing 31 and the first housing 11 are connected by a connecting member 20 passing through the through hole 31a and the nut in sequence.

[0064] In this embodiment, a fixing nut 12 can be arranged at the edge of the end face of the first housing 11. The fixing nut 12 can be bonded or welded to the inner surface or the outer surface of the first housing 11. Here, when the first housing 11 is made of plastic, the fixing nut 12 can also be injection-molded in the first housing 11 in an insert way and exposed on the surface of the first housing 11. Correspondingly, a through hole 31a is opened on the second housing 31. The through hole 31a extends through in the direction in which the second housing 31 is butted against the first housing 11. When the second housing 31 is rotationally engaged, the through hole 31a corresponds to the fixing nut 12. Thus, after the connecting member 20 passes through the through hole 31a, it is fixed in the fixing nut 12, thereby thread-fixing the speaker assembly 30 to the main body assembly 10, thus playing a role in preventing detachment and anti-theft in the axial direction of the main body assembly 10. The connecting member 20 here can be a bolt, a screw or a screw rod, etc., which is not limited here.

[0065] Please combine Figure 2 , Figure 3 andFigure 4 and Figures 7 to 10 In one embodiment, the security camera 100 further includes a control component 18, and the control component 18 is disposed in the installation groove 11a;

[0066] The speaker assembly 30 further includes a speaker elastic sheet 35. One end of the speaker elastic sheet 35 is electrically connected to the speaker unit 33, and the other end is exposed at the end of the second housing 31;

[0067] The main body assembly 10 further includes a speaker conductive column 17. The speaker conductive column 17 is disposed in the installation groove 11a. One end of the speaker conductive column 17 is electrically connected to the control component 18, and the other end is exposed at the opening of the installation groove 11a;

[0068] The first housing 11 is rotationally engaged with the second housing 31 so that the other end of the speaker conductive column 17 is electrically connected to the other end of the speaker elastic sheet 35.

[0069] In this embodiment, in order to simplify the internal structure of the speaker assembly 30, the speaker assembly 30 and the main body component share a control component 18. Therefore, when assembling the speaker assembly 30, it is necessary to electrically connect the speaker unit 33 to the control component 18 in the installation groove 11a at the same time, so as to realize the sound function and the supply of electric energy. Therefore, a speaker elastic sheet 35 is further disposed in the second housing 31. The material of the speaker elastic sheet 35 is metal and is fixed in the second housing 31 through a fixing structure. The fixing structure can be a elastic sheet bracket, which is made of plastic. One end of the speaker elastic sheet 35 is electrically connected to the speaker unit 33 through a wire, and the other end is press-fitted into the through hole of the elastic sheet bracket and protrudes from the outer surface of the second housing 31.

[0070] Correspondingly, the main body assembly 10 further includes a speaker conductive column 17, which is fixed in the installation groove 11a through a fixing structure. The fixing structure is a conductive column bracket, and the material is also plastic, and is fixed on the control component 18 by a chip mounting method to improve the accuracy. One end of the speaker conductive column 17 is electrically connected to the control component 18, and the other end is exposed at the opening of the installation groove 11a. Thus, when the second housing 31 is rotationally engaged with the first housing 11, the speaker elastic sheet 35 is in contact with the speaker conductive column 17 and is electrically connected. Of course, in order to realize the loop current, two speaker elastic sheets 35 and two speaker conductive columns 17 are provided. The two speaker elastic sheets 35 are spaced in two cavities of the elastic sheet bracket, and the two speaker conductive columns 17 are spaced through two cavities of the conductive column bracket, so as to form a loop after contact, realizing the control and power supply of the speaker assembly 30. The electrical connection in this way is simple and convenient, and can be quickly disconnected when replacing the speaker assembly 30, ensuring safe disassembly and assembly.

[0071] Please refer to Figure 4 andFigure 5 , and Figures 7 to 10 , in one embodiment, the speaker assembly 30 further includes two spaced detection elastic pieces 37. The two ends of the two detection elastic pieces 37 facing the speaker unit 33 are connected, and the other two ends of the two detection elastic pieces 37 are exposed at the end of the second housing 31;

[0072] The main body assembly 10 further includes a detection conductive post 19. One end of the detection conductive post 19 is electrically connected to the control assembly 18, and the other end is exposed at the notch of the installation groove 11a;

[0073] The first housing 11 is rotationally engaged with the second housing 31 so that the other end of the detection conductive post 19 is electrically connected to the other end of the detection elastic piece 37.

[0074] In this embodiment, in order to further ensure that the speaker assembly 30 and the main body assembly 10 are installed in place and electrically connected in place, the speaker assembly 30 is further provided with two detection elastic pieces 37, the material of which is metal, and the main body assembly 10 is further provided with corresponding detection conductive posts 19, the material of which is also metal. The parts of the two detection elastic pieces 37 located inside the second housing 31 are connected and conducted, and are assembled on another elastic piece bracket by interference fit, and the parts exposed at the end of the second housing 31 are spaced apart. The two detection conductive posts 19 are spaced apart and can be fixedly arranged at the notch position of the installation groove 11a through two cavities of another conductive post bracket. For example, they are fixed on the control assembly 18 in a patch manner, and the end of the detection conductive post 19 located inside the installation groove 11a is electrically connected to the control assembly 18. In this way, after the first housing 11 and the second housing 31 are docked, the detection elastic piece 37 and the detection conductive post 19 are misaligned. After the two are rotationally engaged, the two detection elastic pieces 37 will respectively abut against the two detection conductive posts 19, thereby completing the connection of the detection circuit. The setting of this detection structure can, after the connection and conduction of the speaker assembly 30 and the main body assembly 10 are completed, send a voice reminder to the user through the control assembly 18 to rotate in place, and the connector 20 can be locked, so as to ensure the assembly accuracy of the security camera 100, improve its use performance, and enhance the use experience.

[0075] Please combine Figure 2 and Figure 3, in one embodiment, the control component 18 includes a main circuit board 181 and a sub-circuit board 183. The main circuit board 181 is disposed on the bottom wall of the installation groove 11a and is electrically connected to the battery 15. The imaging unit 13 includes a sub-circuit board bracket 133 and a camera 131 disposed on the sub-circuit board bracket 133. The sub-circuit board 183 is disposed at one end of the sub-circuit board bracket 133 away from the main circuit board 181 and is arranged side by side with the battery 15 in the installation groove 11a. The speaker conductive post 17 and the detection conductive post 19 are spaced apart on the sub-circuit board 183.

[0076] In this embodiment, in order to facilitate electrical conduction with the speaker assembly 30, the control component 18 is divided into a main circuit board 181 and a sub-circuit board 183. The main circuit board 181 is disposed on the bottom wall of the installation groove 11a, and the connection method can be threaded connection or snap connection. Pins are surface-mounted on the main circuit board 181. There are two batteries 15, and the two batteries 15 are arranged side by side in the installation groove 11a, and the bottom abuts against the pins on the main circuit board 181, so as to realize conduction with the main circuit board 181 and provide electrical energy for it, which is simple and convenient and can improve the disassembly and assembly convenience of the battery 15. The imaging unit 13 includes a sub-circuit board bracket 133 and a camera 131. The camera 131 is located in the middle in the axial direction of the first housing 11, so as to expand the monitoring range. The sub-circuit board bracket 133 is fixed to the bottom of the first housing 11 and is electrically connected to the main circuit board 181. For example, it can be electrically connected through a flexible circuit board or a wire, and the main circuit board 181 provides electrical energy and transmits control signals for it. Of course, necessary circuit systems and modules of the camera 131 are also provided on the sub-circuit board bracket 133, which will not be elaborated here. The sub-circuit board 183 is disposed at one end of the sub-circuit board bracket 133 facing away from the main circuit board 181, and the connection method between the two can be threaded, inserted or snapped, etc., so as to be closer to the opening of the installation groove 11a. The detection conductive post 19 and the speaker conductive post 17 are surface-mounted on the sub-circuit board 183 through a bracket. In this way, the components in the installation groove 11a are assembled more tightly, effectively saving space and facilitating electrical connection with the speaker.

[0077] Optionally, in order to better limit the battery 15, the main body assembly 10 further includes a battery compartment 16. The battery compartment 16 is formed with a battery slot matching the battery 15. The bottom of the battery compartment 16 is detachably fixed to the bottom of the first housing 11. For example, it is threadedly connected. The main circuit board 181 is fixed to the bottom end face of the battery compartment 16, which is convenient for electrical connection with the battery 15. At the same time, the battery compartment 16 also has an outer edge adapted to the opening of the installation groove 11a, so as to form a good sealing effect to protect the control component 18 and the imaging unit 13 and prevent external dust and water vapor from entering. Of course, avoidance holes need to be opened on the battery compartment 16 so that the detection conductive post 19 and the speaker conductive post 17 are exposed.

[0078] Please continue to refer to Figure 2 , in one embodiment, the security camera 100 further includes a first seal 50, and the first seal 50 is clamped between the opening edge of the mounting groove 11a and the end face of the second housing 31.

[0079] In this embodiment, the first seal 50 can be a sealing ring or a sealing cotton strip, or other sealing structures, which are not limited herein. When it is a sealing ring, a soft rubber material can be selected, and the sealing effect is good. Clamping the first seal 50 between the opening edge of the mounting groove 11a and the end face of the second housing 31 can ensure the sealing performance at the connection position between the two, thereby effectively improving the waterproof performance of the installed camera 131. Optionally, a sealing groove is provided on the periphery of the mounting portion, and the first seal 50 is arranged in the annular sealing groove, and the second housing 31 presses the first seal 50, thereby forming a compression fit to prevent the movement of the first seal 50, improving the sealing effect, and also improving the damping feeling when the speaker assembly 30 rotates, enhancing the user experience of the product.

[0080] After the combination of the above embodiments, the structural design of the security camera 100 is ingenious and the functions are rich. The quick disassembly and detection of the entire speaker assembly 30 are realized, and it is convenient to replace the battery 15. At the same time, the waterproof requirement of the quick disassembly part is also realized.

[0081] Please refer to Figures 4 to 6 , in one embodiment, the second housing 31 includes a bottom shell 313 and an upper cover 311. The bottom shell 313 and the upper cover 311 are detachably connected and enclose a receiving cavity. The speaker unit 33 is arranged in the receiving cavity and divides the receiving cavity into a front cavity 31b and a rear cavity 31c. The surface of the bottom shell 313 facing away from the upper cover 311 forms the first connecting portion 1131.

[0082] In this embodiment, to facilitate the assembly of the speaker unit 33, the second housing 31 is composed of two detachable parts. For example, the upper cover 311 and the bottom shell 313 are connected by threads, providing good connection stability. Of course, they can also be connected by snap-fitting or plugging. To ensure the performance of the speaker unit 33, an accommodation cavity is formed after the upper cover 311 and the bottom shell 313 are connected, which has a certain waterproof effect. The speaker unit 33 is disposed therein and can be divided into a front cavity 31b and a rear cavity 31c. The sound hole 31d is opened on the front cavity 31b for realizing the sound generation function. The bottom shell 313 forms the above-mentioned first connection portion 1131. And to facilitate the cooperation with the mounting plate 115 of the first housing 11, a relief groove is recessed inward from the middle of the bottom shell 313 toward the end face of the first housing 11. The first connection portion 1131 is provided on the groove wall of the relief groove and cooperates with the outer surface of the mounting plate 115. That is, the bottom shell 313 covers the end face of the first housing 11 through the relief groove, further improving the sealing effect.

[0083] Please refer to Figure 5 and Figure 6 , in an embodiment, the security camera 100 further includes an elastic member 40. A connection cavity is formed by enclosing the upper cover 311 and the bottom shell 313. The through hole 31a penetrates the cavity wall of the connection cavity. The elastic member 40 is disposed in the connection cavity. One end of the connecting member 20 passes through the middle of the through hole 31a and the elastic member 40, and the other end abuts against the cavity wall of the connection cavity.

[0084] For the convenience of assembly, during the assembly process of the speaker assembly 30, the connecting member 20 is fixed to the second housing 31. That is, holes are formed at the edge of the bottom shell 313. Correspondingly, holes are also formed in the upper cover 311. The holes of both correspond to form the through hole 31a. And the edge of the bottom shell 313 is butted against the edge of the upper cover 311 to form a connection cavity. The elastic member 40 is a spring or a spring tube, and the connecting member 20 is a screw. The threaded section of the connecting member 20 is inserted into the elastic member 40 and the through hole 31a, and its nut section is inserted into the hole of the upper cover 311. A convex is protruded between the threaded section and the nut section, so that the connecting member 20 is clamped in the connection cavity and will not slide out toward the hole of the upper cover 311, and will not slide out toward the hole of the bottom shell 313 under the abutment of the elastic member 40, forming an installation structure. In this way, without rotation and engagement, it is ensured that the threaded section of the connecting member 20 does not protrude from the surface of the bottom shell 313, thus not affecting the rotational engagement between the first housing 11 and the second housing 31, effectively ensuring the connection convenience.

[0085] In order to further improve the waterproof performance of the speaker assembly 30, in one embodiment, a fixing step 3111 is protruded from the cavity wall of the front cavity 31b, the periphery of the speaker unit 33 is fixed to the fixing step 3111, and a waterproof adhesive 38 is clamped between the fixing step 3111 and the periphery of the speaker unit 33;

[0086] And / or, a waterproof breathable film 39 is attached to the surface of the speaker unit 33 facing the front cavity 31b;

[0087] And / or, a rib 3113 is protruded from the upper cover 311 in the rear cavity 31c, the rib 3113 extends toward the bottom case 313 and abuts against the surface of the bottom case 313 facing away from the first housing 11, and a second seal 70 is clamped between the rib 3113 and the bottom case 313.

[0088] In this embodiment, a fixing step 3111 is protruded from the inner wall surface of the upper cover 311, and the fixing step 3111 extends toward the bottom case 313. Since the sound hole 31d is formed in the cavity wall of the front cavity 31b, when the speaker unit 33 is fixed to the fixing step 3111, the waterproof adhesive 38 is provided between the two. On the one hand, the connection between the two can be realized, and on the other hand, the sealing performance of the connection can be realized, effectively reducing the intrusion of water vapor and improving the waterproof effect. The waterproof adhesive 38 here can be a waterproof double-sided tape or a waterproof liquid glue, etc.

[0089] On the basis of having or not having the waterproof adhesive 38, in order to ensure the waterproof performance of the surface of the speaker unit 33 facing the sound hole 31d, a waterproof breathable film 39 is attached to this surface. The waterproof breathable film 39 can effectively block water vapor but allow the passage of air flow. For example, a waterproof double-sided tape or a polytetrafluoroethylene film, etc. can be selected, which is not limited here, so as to effectively improve the waterproof performance of the speaker assembly 30.

[0090] Of course, on the basis of having or not having the waterproof adhesive 38 and the waterproof breathable film 39, ribs 3113 can also be provided on the cavity wall of the rear cavity 31c, that is, ribs 3113 are protruded from the upper cover 311, and the ribs 3113 extend toward one side of the bottom case 313 and abut against the bottom case 313, so as to form a closed rear cavity 31c to prevent water vapor from entering. At the same time, a second seal 70 is also provided between the rib 3113 and the bottom case 313. The second seal 70 can be a software seal ring or glue, etc., which is not limited here. When a seal ring is selected, a groove can be formed on the inner surface of the bottom case 313, the seal ring is arranged in the groove, and the rib 3113 also abuts against the inside of the groove, so as to improve the sealing performance while ensuring the connection stability.

[0091] In addition, in order to further improve the stability of the speaker unit 33, a support structure is also convexly provided in the middle of the bottom case 313 for abutting against the surface of the speaker unit 33 facing away from the upper cover 311. At the same time, in order to improve earthquake resistance, an elastic support member, such as a support foam or silica gel, etc., is also provided between the support structure and the speaker unit 33 to enhance the protection of the speaker unit 33.

[0092] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention.
