For example, mid-range speakers and subwoofers are larger in size and heavier than tweeters, and the material used to make the vehicle roof is relatively soft and the structural strength is not high, which cannot meet the installation requirements of large-sized speakers. As a result, only small-sized speakers can be installed on the roof of the vehicle, affecting the vehicle's audio-visual effects.

[0043] Reference Figures 1 to 3 The vehicle provided in the present invention includes a body support. In some embodiments, the body support is configured as the vehicle's body-in-white. The body support includes body structural members, covering members, and reinforcement members. The body structural members include, for example, the load-bearing beams and frame structures of the vehicle body. The body covering members are used to wrap panels of the body structural members, such as the roof, engine cover, and fenders. The body support includes a roof sheet metal 100. In one embodiment, the roof sheet metal 100 is located in the upper half of the vehicle body and extends from the front to the rear of the vehicle.

The surface material can be made of glass fiber, woven fabric, artificial leather, non-woven fabric and other materials, and the foam layer can be made of polyurethane, cross-linked polyethylene and other materials.

[0046] The speaker 200 is installed on the roof sheet metal 100 and is located on the lower side of the roof sheet metal 100. The sound played by the speaker 200 can be directly transmitted downward to the interior of the vehicle. Since the roof sheet metal 100 has excellent structural strength, it can meet the installation requirements of different types, especially large-sized speakers 200, so that the corresponding type of speaker 200 can be installed on the roof of the vehicle according to needs to improve the vehicle's audio-visual effects.

[0047] The speaker 200 can be installed at the front, middle or rear of the roof sheet metal 100, or the speakers 200 can be installed at different positions at the front, middle and rear of the roof sheet metal 100. It can also be further configured that different types of speakers 200 are installed at different positions at the front, middle and rear of the roof sheet metal 100. In some specific embodiments, the roof sheet metal 100 includes a front skylight 110 and a rear skylight 110, and the speaker 200 is located between the front skylight 110 and the rear skylight 110; or Figure 1 In the illustrated embodiment, the roof panel 100 includes a skylight 110 , and the speaker 200 is located behind the skylight 110 .

[0048] In some embodiments, a plurality of speakers 200 are provided, and the plurality of speakers 200 are symmetrical with respect to the XOZ plane, so that the sound effects in the left and right areas of the vehicle are balanced. Figure 2 In the illustrated embodiment, two speakers 200 are provided. The two speakers 200 are located on the rear side of the skylight 110 and are symmetrically distributed left and right.

[0049] In some specific embodiments, the vehicle includes a tweeter, a midrange speaker, a woofer and a subwoofer.

[0050] The speaker 200 may be mounted on the top cover sheet metal 100 by means other than bonding, threading, or snapping. In some embodiments, the speaker 200 is secured to the lower surface of the top cover sheet metal 100 by bonding; for example, a portion of the lower surface of the top cover sheet metal 100 may be flat to provide a smooth bonding surface for the speaker 200. A colloid may be pre-coated on the surface of the top cover sheet metal 100, and then the speaker 200 may be bonded to the lower surface of the top cover sheet metal 100.

[0051] In some embodiments, the speaker 200 is threadedly connected to the top cover sheet metal 100; for example, holes are provided on both the top cover sheet metal 100 and the speaker 200, and the speaker 200 is installed on the top cover sheet metal 100 by locking threaded fasteners into the holes in the top cover sheet metal 100 and the speaker 200. When the speaker 200 fails, the speaker 200 can be repaired or replaced by removing the threaded fasteners.

[0052] In some embodiments, a protrusion is provided on the underside of the roof sheet metal 100, and the speaker 200 is mounted at the lower end of the protrusion. This places the speaker 200 closer to the vehicle interior, thereby meeting the sound transmittance requirements of the speaker 200 and preventing the speaker 200 from being too far from the ceiling 300, which would affect the sound. In a specific embodiment, the speaker 200 is provided with multiple holes. The underside of the roof sheet metal 100 is provided with multiple protrusions, each of which has a hole. The holes on each protrusion correspond one-to-one with the holes on the speaker 200. The speaker 200 is mounted to the roof sheet metal 100 by locking threaded fasteners into the protrusions and the holes on the speaker 200. Alternatively, in another embodiment, at least a portion of the lower surface of the protrusion is flat, and the speaker 200 is secured to the lower surface of the protrusion by adhesive bonding.

[0053] Reference Figure 3 and Figure 4 In one embodiment, the vehicle further includes a first bracket 400, which is mounted on the lower side of the roof sheet metal 100, and the speaker 200 is mounted on the first bracket 400, and is at least partially located on the lower side of the first bracket 400; the speaker 200 is mounted on the roof sheet metal 100 through the first bracket 400, which, on the one hand, makes the speaker 200 closer to the ceiling 300, meeting the sound transmittance requirement of the speaker 200, and on the other hand, simplifies the structure of the roof sheet metal 100, facilitating the processing and manufacturing of the roof sheet metal 100.

[0054] The connection method between the first bracket 400 and the top cover sheet metal 100 is not limited to bonding, threading, clamping, etc. In some embodiments, the first bracket 400 is fixed to the lower surface of the top cover sheet metal 100 by bonding; for example, a portion of the lower surface of the top cover sheet metal 100 is set to a plane, and a colloid is pre-coated on the surface of the top cover sheet metal 100, and then the first bracket 400 is bonded and fixed to the lower surface of the top cover sheet metal 100. Or, Figure 3 In the embodiment shown, the first bracket 400 is threadedly connected to the top cover sheet metal 100; for example, holes are provided on the top cover sheet metal 100 and the speaker 200, and the first bracket 400 is installed on the top cover sheet metal 100 by locking threaded fasteners into the holes in the top cover sheet metal 100 and the first bracket 400, making the installation of the first bracket 400 to the top cover sheet metal 100 more convenient.

[0055] It should be noted that in the case where the speaker 200 is installed on the roof sheet metal 100 through the first bracket 400, the speaker 200 can be pre-installed on the first bracket 400, and the two form an assembly and are supplied as a whole. When installing the speaker 200, it is only necessary to fix the first bracket 400 to the roof sheet metal 100 to complete the assembly of the speaker 200, which can reduce the operating procedures in the car and make the installation of the speaker 200 more convenient.

[0056] The first bracket 400 includes a main body 410 and a mounting post 420 provided on the upper side of the main body 410. At least part of the speaker 200 is located on the lower side of the main body 410. The upper end of the mounting post 420 is threadedly connected to the top cover sheet metal 100, and the upper end of the mounting post 420 can abut against the lower surface of the top cover sheet metal 100. By providing the mounting post 420, the speaker 200 is brought closer to the ceiling 300, meeting the sound output requirements of the speaker 200. The threaded fasteners are passed through the interior of the mounting post 420 and connected to the top cover sheet metal 100, which can increase the penetration depth of the threaded fasteners in the first bracket 400, thereby improving the connection strength between the first bracket 400 and the top cover sheet metal 100. Figure 1 、 Figure 3 and Figure 4 In the illustrated embodiment, a first hole 120 is provided on the top cover sheet metal 100, and each mounting column 420 is provided with a second hole 421. The positions of the first hole 120 and the second hole 421 correspond to each other, and the threaded fastener is configured as a bolt, which is passed through the first hole 120 and the second hole 421 to fix the first bracket 400 to the lower side of the top cover sheet metal 100.

[0057] In one embodiment, a plurality of mounting columns 420 are provided, thereby realizing multi-point connection and support between the first bracket 400 and the top cover sheet metal 100, and reducing stress concentration at the connection position between the two; in addition, a plurality of mounting columns 420 are arranged at circumferential intervals along the first bracket 400, and the plurality of mounting columns 420 can be arranged to form a space for accommodating the speaker 200, so that some speakers 200 can be installed on the upper side of the main body 410.

[0058] It is understandable that in order to meet the requirements of the vehicle in terms of reducing wind resistance, improving endurance, and aesthetics, the roof sheet metal 100 of the vehicle has a curved configuration. Therefore, different positions of the roof sheet metal 100 have different distances from the roof 300 in the Z direction. Based on this, in one embodiment, at least two mounting columns 420 are provided with different heights. The mounting column 420 with a larger height is located at a position where the distance between the roof sheet metal 100 and the roof 300 is larger, and the mounting column 420 with a smaller height is located at a position where the distance between the roof sheet metal 100 and the roof 300 is smaller. This allows the mounting column 420 to meet the installation requirements of different positions of the roof sheet metal 100 and to adjust the direction of the lower side of the speaker 200 so that the speaker 200 sounds toward the interior of the vehicle. Figure 4 In the embodiment shown, the first bracket 400 includes three mounting columns 420, which are arranged at intervals along the circumference of the first bracket 400, and the heights of the three mounting columns 420 are all different. The distribution of the three mounting columns 420 is relatively dispersed, so that the area where the top cover sheet metal 100 is installed with the first bracket 400 is evenly stressed, and the upper ends of the mounting columns 420 are connected to different heights of the top cover sheet metal 100.

[0059] Furthermore, in one embodiment, the upper surface of the mounting column 420 is a plane, an inclined surface or a curved surface, so that the upper surface of the mounting column 420 matches the lower surface of the top cover sheet metal 100. The upper surface of the mounting column 420 can be in close contact with the lower surface of the top cover sheet metal 100, thereby increasing the contact area between the two and reducing stress concentration.

[0060] In addition, in other embodiments, a boss can be provided on the upper side of the main body 410 and different positions of the upper surface of the boss can be connected to the top cover sheet metal 100 to achieve the installation of the first bracket 400 to the top cover sheet metal 100 and make the speaker 200 closer to the ceiling 300.

[0061] It should be noted that, by providing a boss or a mounting column 420 on the first bracket 400, a mounting gap 130 can be provided between the upper side of the first bracket 400 and the lower side of the top cover sheet metal 100. The mounting gap 130 can accommodate the speaker 200, and the upper end of the speaker 200 can protrude above the first bracket 400, making the connection between the top cover sheet metal 100 and the speaker 200 more compact, thereby reducing the space occupied by the speaker 200 mounting structure in the vehicle.

[0062] exist Figure 5 and Figure 6 In the illustrated embodiment, the main body 410 has a through hole 411 that passes through and connects to the installation gap 130, the installation column 420 is arranged around the outer periphery of the through hole 411, and the speaker 200 is passed through the through hole 411 and accommodated in the installation gap 130; by arranging the through hole 411 in the first bracket 400, the upper part of the speaker 200 is located on the upper side of the first bracket 400 and accommodated in the installation gap 130, and the lower part of the speaker 200 is located on the lower side of the first bracket 400, and is closer to the ceiling 300, and emits sound toward the vehicle compartment.

[0063] To facilitate the later maintenance and disassembly of the speaker 200, in one embodiment, the speaker 200 includes a main body 210 and an installation portion 220. The installation portion 220 is connected to the peripheral side of the main body 210. The main body 210 is passed through the through hole 411 and accommodated in the installation gap 130. The lower side of the main body 210 can emit sound toward the vehicle compartment. The installation portion 220 is located on the lower side of the first bracket 400 and is detachably connected to the first bracket 400. After the speaker 200 fails, the connection between the first bracket 400 and the mounting portion 220 is released from the bottom of the first bracket 400, and the speaker 200 is taken out downward from the through hole 411 and the mounting gap 130. When installing the speaker 200, the speaker 200 is inserted upward into the through hole 411 and the mounting gap 130, and the mounting portion 220 abuts against the lower side of the first bracket 400, and then the mounting portion 220 is connected to the first bracket 400. Since the speaker 200 and the first bracket 400 are detachably connected, the first bracket 400 does not need to be disassembled during the entire process, and the subsequent maintenance of the speaker 200 is more convenient.

[0064] The detachable connection between the mounting portion 220 and the first bracket 400 is not limited to threaded connection or snap connection. In one embodiment, the mounting portion 220 and the first bracket 400 are provided with cooperating snap connections, enabling the mounting portion 220 to snap into contact with the first bracket 400. For example, one of the mounting portion 220 and the first bracket 400 is provided with a snap, and the other is provided with a snap hole. The snap locks into the snap hole to achieve the snap connection between the mounting portion 220 and the first bracket 400. The speaker 200 can be assembled and disassembled by releasing the snap connection between the mounting portion 220 and the first bracket 400 or snapping the mounting portion 220 into the first bracket 400.

[0065] exist Figure 6 In the illustrated embodiment, the mounting portion 220 is threadedly connected to the first bracket 400. Both the mounting portion 220 and the first bracket 400 are provided with holes for installing threaded fasteners. The speaker 200 is mounted on the first bracket 400 by locking the threaded fasteners into the holes of the mounting portion 220 and the first bracket 400. For example, the threaded fasteners are sequentially inserted into the mounting portion 220 and the first bracket 400 from bottom to top and tightened to mount the speaker 200 on the first bracket 400. To remove the speaker 200, the threaded fasteners are screwed from the bottom side of the first bracket 400 and then pulled downward out of the first bracket 400 and the mounting portion 220, releasing the connection between the mounting portion 220 and the first bracket 400 and removing the speaker 200 from the first bracket 400. Alternatively, the threaded fasteners are locked into the first bracket 400 and the mounting portion 220 from the bottom side of the first bracket 400 to mount the speaker 200 on the first bracket 400.

[0066] Furthermore, the upper side of the first bracket 400 is provided with a plurality of upwardly protruding bosses 430, and the bosses 430 are provided with holes extending through the lower side of the first bracket 400. The mounting portion 220 corresponds to the bosses 430 one by one, and the threaded fasteners are locked into the mounting portion 220 and the bosses 430 to mount the speaker 200 on the first bracket 400. The provision of the bosses 430 can increase the locking depth of the threaded fasteners in the first bracket 400, thereby improving the connection strength between the speaker 200 and the first bracket 400. Figure 5 In the embodiment shown, the bosses 430 and the mounting posts 420 are alternately arranged along the circumference of the first bracket 400, and the bosses 430 are disposed between adjacent mounting posts 420 to fully utilize the gap between the first bracket 400 and the top cover sheet metal 100, thereby making the connection between the top cover sheet metal 100, the first bracket 400 and the speaker 200 more compact and reducing the space occupied by the speaker 200 mounting structure in the Z direction of the vehicle.

[0067] Reference Figure 3 The vehicle further includes a mask 500, which is mounted on the roof 300 and located on the lower side of the speaker 200. The mask 500 is used to protect the speaker 200 to prevent accidental damage to the speaker 200 and to prevent external dust and particles from entering the speaker 200 and affecting the normal sound of the speaker 200. The mask 500 is provided with a sound outlet 510 extending therethrough, and the sound emitted by the speaker 200 is diffused into the vehicle compartment through the sound outlet 510. In one embodiment, referring to Figure 6 The ceiling 300 has a first mounting hole 310 passing through it, the mask 500 is detachably connected to the ceiling 300 and covers the first mounting hole 310, and the portion of the mask 500 covering the first mounting hole 310 is provided with a sound outlet 510, the speaker 200 is located above the mask 500 and is installed between the top cover sheet metal 100 and the ceiling 300, and the sound emitted by the speaker 200 diffuses downward into the vehicle compartment through the sound outlet 510.

The mask 500 blocks the first mounting hole 310 and part of the ceiling 300 around the first mounting hole 310 at the lower side of the first mounting hole 310. The edge of the first mounting hole 310 is not exposed, the lower surface of the ceiling 300 is neater and more beautiful, and it is convenient to disassemble and assemble the mask 500 from the lower side of the ceiling 300.

[0069] A plane perpendicular to the direction in which the first mounting hole 310 penetrates is defined as a projection plane. The projection of the speaker 200 in the projection plane is located inside the projection of the first mounting hole 310 in the projection plane. Therefore, the maximum cross-sectional area of ​​the speaker 200 parallel to the projection plane is smaller than the minimum cross-sectional area of ​​the first mounting hole 310 parallel to the projection plane, so that the speaker 200 can enter and exit the first mounting hole 310. When the speaker 200 needs to be disassembled, the mask 500 is first removed from the lower side of the ceiling 300. After the mask 500 is removed, the first mounting hole 310 is no longer blocked, and the speaker 200 is completely exposed at the first mounting hole 310. The operator's hand or control operating tool moves from the bottom of the ceiling 300 through the first mounting hole 310 to the top of the ceiling 300, and releases the connection between the speaker 200 and the first bracket 400, so that the speaker 200 can be moved to the bottom of the ceiling 300 through the first mounting hole 310 to take out the speaker 200; when the speaker 200 needs to be installed, the speaker 200 is first moved to the top of the ceiling 300 through the first mounting hole 310, and then the speaker 200 is installed on the first bracket 400, and finally the mask 500 is installed on the ceiling 300.

[0070] It should be noted that the traditional speaker 200 is directly fixed to the ceiling 300. Due to the high failure rate of the speaker 200, when the speaker 200 is damaged and repaired, the ceiling 300 and the speaker 200 assembly need to be replaced. The operator needs to bend down to remove the seats, carpets, A / B / C pillars, ceiling 300 mounting bolts and snap-on structures, and then drill into the door hole or lie in the trunk to take out the above parts, and finally replace the speaker 200. The operation is relatively cumbersome, the disassembly space is limited, maintenance is relatively inconvenient, and it is easy to cause material damage during the operation. In the present invention, the speaker 200 is detachably connected to the first bracket 400, and the mask 500 is detachably connected to the ceiling 300. By removing the mask 500, the speaker 200 can be exposed at the first mounting hole 310, and the speaker 200 can pass through the first mounting hole 310. With the help of the first mounting hole 310, the connection between the speaker 200 and the first bracket 400 can be released, and then the speaker 200 can be taken out. There is no need to disassemble the A / B / C pillars, ceiling, etc., the operation is relatively convenient, and after-sales labor hours and material costs are saved.

[0071] In addition, when the speaker 200, the top cover sheet metal 100 and the ceiling 300 are assembled for the first time, the speaker 200 is first installed on the first bracket 400 to form an assembly. The assembly formed by the speaker 200 and the first bracket 400 can be supplied as a whole. The assembly is installed as a whole on the lower side of the top cover sheet metal 100. The mask 500 is pre-installed on the ceiling 300 to form an assembled part. The assembled part is then installed as a whole on the top cover sheet metal 100 to complete the assembly of various components.

[0072] The detachable connection between the mask 500 and the ceiling 300 is not limited to snap connection, thread connection, etc. In order to improve the connection strength between the mask 500 and the ceiling 300, in one embodiment, referring to Figure 6 The vehicle also includes a second bracket 600, which is fixed to the upper side of the roof 300. Part of the mask 500 passes through the roof 300 and is detachably connected to the second bracket 600, so that the mask 500 is detachable relative to the roof 300, and the connection strength between the second bracket 600 and the mask 500 is high, so that the mask 500 is firmly connected to the roof 300, reducing the risk of shaking between the roof 300 and the mask 500 when the vehicle passes through bumpy roads, thereby avoiding damage to the roof 300, the mask 500 and other related components due to bumps.

[0073] In addition, the second bracket 600 has a second mounting hole 610 that penetrates therethrough, and the second mounting hole 610 is connected to the first mounting hole 310. The projection formed by the speaker 200 in the projection plane is located inside the projection formed by the second mounting hole 610 in the projection plane. Therefore, the speaker 200 can also pass through the second mounting hole 610. When disassembling the speaker 200, the speaker 200 can be moved to the bottom of the ceiling 300 through the second mounting hole 610 and the first mounting hole 310 in sequence and taken out.

[0074] In one embodiment, the second bracket 600 is configured in an annular shape, and the projection of the second mounting hole 610 in the projection plane is smaller than the projection of the first mounting hole 310 in the projection plane, so as to increase the contact area between the second bracket 600 and the ceiling 300 and improve the connection strength of the connection between the mask 500 and the ceiling 300. Alternatively, Figure 4 In the embodiment shown, the second bracket 600 is arranged in a ring shape, and the second bracket 600 is arranged around the outer periphery of the first mounting hole 310. The projection of the second mounting hole 610 in the projection plane is greater than or equal to the projection of the first mounting hole 310 in the projection plane. The ceiling 300 blocks the second bracket 600, and no other parts are exposed at the mask 500, which can improve the aesthetics of the lower surface of the ceiling 300.

[0075] In one embodiment, referring to Figure 6 The first bracket 400 and the second bracket 600 are spaced apart in the Z direction, providing space for movement in the Z direction to prevent friction or collision on bumpy roads. Furthermore, the mounting portion 220 of the speaker 200 is located between the first bracket 400 and the second bracket 600 in the Z direction. The lower end of the threaded fastener used to secure the mounting portion 220 to the first bracket 400 is located between the first bracket 400 and the second bracket 600, or within the second mounting hole 610.

[0076] In a specific embodiment, the second bracket 600 is bonded to the upper surface of the ceiling 300 using hot melt adhesive, and the connection between the second bracket 600 and the ceiling 300 is stable and the assembly efficiency is high. Figure 4 In the illustrated embodiment, the second bracket 600 is further provided with a glue hole 620 for accommodating hot melt glue to increase the adhesive area of ​​the second bracket 600 and enhance the connection strength between the second bracket 600 and the ceiling 300 .

[0077] The mask 500 includes a sound outlet portion 520, which is provided with a plurality of sound outlet holes 510 extending therethrough. A portion of the sound outlet portion 520 is disposed within the first mounting hole 310. The upper end of the sound outlet portion 520 abuts the lower end of the speaker 200, thereby maintaining a relatively stable position of the mask 500 and the speaker 200 and reducing the likelihood of abnormal noise from the speaker 200 due to jolts. The mask 500 also includes a connecting portion 530, which surrounds the outer periphery of the sound outlet portion 520 and abuts the underside of the ceiling 300. The ceiling 300, the mask 500, and the speaker 200 are mutually restrained in the Z direction, further stabilizing the position of the speaker 200.

[0078] In one embodiment, a flexible pad is sandwiched between the upper end of the sound outlet 520 and the lower end of the speaker 200, achieving a flexible connection between the sound outlet 520 and the speaker 200. This provides a more stable abutment between the two and reduces noise generated by friction. In one embodiment, the upper end of the sound outlet 520 and the lower end of the speaker 200 abut against each other along the X, Y, and Z directions, further stabilizing the connection. For example, one of the sound outlet 520 and the speaker 200 is provided with a slot, and the other is provided with a plug-in post. The plug-in post is inserted into the slot along the Z direction, thereby limiting the position of the sound outlet 520 and the speaker 200 in multiple directions.

[0079] The connection method between the mask 500 and the second bracket 600 is not limited to threaded connection, clamping, etc. In a specific embodiment, Figure 4 and Figure 7 , a clamping column 540 is provided on the upper side of the mask 500, and a clamping groove 630 is provided on the second bracket 600. The clamping groove 630 is provided on the side wall of the second mounting hole 610, or the clamping groove 630 is located on the outer periphery of the second mounting hole 610 and penetrates the second bracket 600 along the Z direction. The clamping column 540 is clamped in the clamping groove 630, so that the mask 500 is clamped to the second bracket 600. At the same time, the connecting part 530 abuts against the lower side of the ceiling 300, and the sound outlet part 520 abuts against the lower end of the speaker 200. When the mask 500 needs to be removed, the lifting tool can be used to lift the connecting part 530 to release the clamping column 540 from the clamping groove 630, and then the mask 500 can be removed from the ceiling 300. Figure 7In the illustrated embodiment, the locking post 540 is disposed on the upper side of the connecting portion 530 and located at the periphery of the sound outlet portion 520 to avoid the sound outlet hole 510 so that the speaker 200 can produce sound normally.

[0080] like Figure 7 In the embodiment shown, a plurality of the clamping posts 540 and the clamping slots 630 are provided. Some of the clamping slots 630 are provided on the sidewalls of the second mounting hole 610, and some of the clamping slots 630 are located on the periphery of the second mounting hole 610. The clamping posts 540 are arranged at intervals along the circumference of the connecting portion 530, and the clamping slots 630 are arranged at intervals along the circumference of the second bracket 600. At least one clamping post 540 is clamped into each clamping slot 630. Figure 7 In the embodiment shown, a positioning pin 550 is further provided on the upper side of the connecting portion 530, and the second bracket 600 is further provided with a penetrating positioning hole. The length of the positioning pin 550 is greater than the length of the clamping column 540, and the positioning pin 550 can be inserted into the positioning hole. The positioning pin 550 is used to provide a guide for the fitting clamping of the clamping column 540 and the clamping groove 630 during the assembly process of the mask 500 and the second bracket 600, and to position the relative position of the mask 500 and the second bracket 600.

[0081] In one embodiment, the lower end of the speaker 200 is received in the second mounting hole 610, and the speaker 200 is sequentially inserted through the second bracket 600, the first bracket 400, and the mounting gap 130 between the first bracket 400 and the top cover sheet metal 100. This fully utilizes the space between the top cover sheet metal 100 and the ceiling 300. Furthermore, the speaker 200 is positioned close to the sound outlet 520, meeting the required sound output ratio of the speaker 200. Alternatively, the lower end of the speaker 200 can be received in the first mounting hole 310, placing the speaker 200 even closer to the sound outlet 520.
