Description

Technical Field

[0001] This utility model relates to the technical field of audio equipment, and in particular to an adjustable angle wall-mounted audio system. Background Technology

[0002] As living standards improve, people's demands for audio equipment have expanded beyond basic sound production. In various usage scenarios, wall-mounted speakers have gained widespread popularity due to their advantages such as space saving, easy installation, no floor space occupation, and good integration with interior décor. In home theater systems, wall-mounted speakers can be strategically placed around the room to create an immersive surround sound effect; in commercial display areas, wall-mounted speakers can be flexibly installed according to spatial layout and display needs, providing customers with clear product introductions and background music.

[0003] However, existing wall-mounted speakers have the following shortcomings in practical use: most traditional wall-mounted speakers are directly fixed to the wall, and once installed, their angle cannot be changed. This fixed installation method makes it difficult for the speakers to provide optimal sound propagation when facing different usage environments and user needs. For example, in a large conference room, if the speakers are fixed high on the wall and the angle is not adjustable, people in the back rows may not be able to hear the sound clearly; in a family living room, if the sofa position changes, the fixed-angle wall-mounted speakers cannot adjust the sound emission angle according to the new listening position, resulting in poor sound quality. In view of this, the adjustable-angle wall-mounted speaker of this application is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable-angle wall-mounted speaker that can adjust the sound emission angle according to different usage environments and user needs to improve the sound propagation effect.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0035] like Figures 1 to 8As shown, in one embodiment, an adjustable angle wall-mounted speaker 1 includes a cabinet 10 and a wall-mounting assembly. The wall-mounting assembly includes a back frame 20, a support rod 21, and a locking block 22. The back frame 20 and the support rod 21 are rotatably mounted on the cabinet 10 at intervals. A sliding hole 201 is provided at the end of the back frame 20 away from the cabinet 10. The end of the support rod 21 away from the cabinet 10 is slidably engaged with the sliding hole 201. A plurality of slots 202 are provided on the back frame 20. Each slot 202 is equidistantly distributed along one side of the opening direction of the sliding hole 201. The locking block 22 passes through the support rod 21 and is located in the sliding hole 201. A locking block 220 is provided on the locking block 22. When the back frame 20 rotates relative to the cabinet 10 to form an angle, the support rod 21 drives the locking block 22 to slide back and forth relative to the sliding hole 201, so that the locking block 220 is engaged with any slot 202.

[0036] It should be noted that the enclosure 10 is used to install electronic components such as speakers, circuit boards, and batteries. One end of the back frame 20 and one end of the support rod 21 are rotatably connected to one side of the enclosure 10, and there is a gap between the positions where the back frame 20 and the support rod 21 are rotatably connected to the enclosure 10. Furthermore, a sliding hole 201 is provided on the end of the back frame 20. The sliding hole 201 extends from the end of the back frame 20 near the box 10 to the other end. The end of the support rod 21 away from the box 10 is slidably engaged with the sliding hole 201. The sliding hole 201 is an oblong hole structure, so that the end of the support rod 21 away from the box 10 can slide back and forth relative to the sliding hole 201. When the end of the support rod 21 away from the box 10 slides to the end of the sliding hole 201 near the box 10, the support rod 21 and the back frame 20 are both parallel to one side of the box 10. When the end of the support rod 21 away from the box 10 slides to the end of the sliding hole 201 away from the box 10, the support rod 21 supports the back frame 20 to form an angle with one side of the box 10. Thus, the end of the support rod 21 away from the housing 10 slides back and forth within the sliding hole 201, allowing the angle between the back frame 20 and the housing 10 to gradually increase or decrease. Furthermore, since the sliding hole 201 has an oblong structure, both sides of the sliding hole 201 are parallel to each other. The back frame 20 has several slots 202, each slot 202 being equidistantly arranged along the opening direction of the sliding hole 201 on one side, and one end of each slot 202 communicating with the sliding hole 201. Furthermore, the locking block 22 passes through the end of the support rod 21 away from the housing 10, and since the end of the locking block 22 away from the housing 10 is slidably engaged with the sliding hole 201, the locking block 22 is also located within the sliding hole 201. Furthermore, the locking block 22 is provided with a latching block 220, which extends perpendicularly to the axis of the locking block 22. When the locking block 22 slides back and forth within the sliding hole 201 relative to the back frame 20, the latching block 220 can engage with any of the latching slots 202, thereby making the angle between the back frame 20 and the cabinet 10 adjustable. This allows the speaker to adjust its angle to provide optimal sound propagation in different usage environments and user needs, thus improving the user experience.

[0037] like Figures 6 to 7 As shown, in one embodiment, the support rod 21 includes a rod body 210, a first protrusion 211 and a second protrusion 212. The first protrusion 211 and the second protrusion 212 are respectively disposed at both ends of the rod body 210, and the first protrusion 211 and the second protrusion 212 are respectively located on two opposing sides of the rod body 210. The first protrusion 211 is slidably engaged with the sliding hole 201, and the second protrusion 212 is rotatably connected to the housing 10.

[0038] It should be noted that both the first protrusion 211 and the second protrusion 212 are cylindrical structures. The first protrusion 211 and the second protrusion 212 are respectively located at both ends of the rod 210, and are situated on opposite sides of the rod 210. The second protrusion 212 is rotatably connected to the housing 10. For example, a bearing seat is integrally formed on one side of the housing 10, and circular shaft holes are formed at both ends of the bearing seat. These two circular shaft holes are rotatably connected to the second protrusion 212 and the back frame 20, respectively. Furthermore, the diameter of the first protrusion 211 is the same as the width of the sliding hole 201, allowing the first protrusion 211 to reciprocate within the sliding hole 201.

[0039] like Figure 7 As shown, in one embodiment, a through hole 2110 is provided on the first protrusion 211, the through hole 2110 passes through both ends of the first protrusion 211 and connects them, and the locking block 22 passes through the through hole 2110.

[0040] It should be noted that a through hole 2110 is coaxially provided on the first protrusion 211, and the locking block 22 is coaxially inserted in the through hole 2110, with both ends of the locking block 22 extending out from both ends of the through hole 2110, so that the locking block 22 can slide along the axial direction of the first protrusion 211.

[0041] like Figure 3 , Figure 6 , Figure 8 As shown, in one embodiment, the locking block 22 further includes a shaft post 221 and a block 222. The shaft post 221 passes through the through hole 2110, the block 222 slides in the sliding hole 201, and the locking block 220 is disposed on the block 222.

[0042] It should be noted that the shaft post 221 has a cylindrical structure, and the block 222 has a flat square structure. The block 222 is set on the shaft post 221, and the axis of the block 222 coincides with the axis of the shaft post 221, so that the block 222 is set on the shaft post 221 coaxially and perpendicularly. When the first protrusion 211 slides back and forth in the sliding hole 201, the first protrusion 211 can drive the shaft post 221 and the block 222 to slide in the sliding hole 201 together. The locking block 220 is set on the side of the block 222 facing the slot 202, and one end of each slot 202 is connected to the sliding hole 201. In this way, the block 222 can drive the locking block 220 to engage with any slot 202, thereby making the angle between the back frame 20 and one side of the housing 10 adjustable.

[0043] like Figure 1 , Figures 3 to 5As shown, in one embodiment, the sliding hole 201 includes an elliptical portion 2010 and a square portion 2011. The elliptical portion 2010 and the square portion 2011 are coaxially aligned and interconnected. The first protrusion 211 slides within the elliptical portion 2010, and the block 222 slides within the square portion 2011. Each slot 202 is formed on an inner sidewall of the square portion 2011.

[0044] It should be noted that the width of the minor axis of the elliptical portion 2010 is the same as the width of the minor axis of the square portion 2011, and the width of the major axis of the elliptical portion 2010 is the same as the width of the major axis of the square hole. The difference between the elliptical portion 2010 and the square portion 2011 is that the two ends of the elliptical portion 2010 are semi-circular, while the two ends of the square hole tend to be right-angled. Furthermore, the diameter of the first protrusion 211 is the same as the width of the minor axis of the elliptical portion 2010, allowing the first protrusion 211 to slide appropriately within the sliding hole 201. The width of the block 222 is the same as the width of the minor axis of the square portion 2011, allowing the block 222 to slide appropriately within the square portion 2011. Furthermore, when the first protrusion 211 slides within the elliptical portion 2010, and the shaft post 221 passes through the through hole 2110, the block 222 mounted on the shaft post 221 can be positioned within the square hole. In this way, the block 222 can drive the card block 220 to slide within the square part 2011 and engage with any card slot 202.

[0045] like Figure 3 , Figure 6 , Figure 8 As shown, in one embodiment, the locking block 22 further includes a stop block 223, which is disposed on the end of the shaft post 221 away from the block 222. The wall-mounted assembly also includes an elastic element 23, which is sleeved on the shaft post 221. The two ends of the elastic element 23 abut against the stop block 223 and the rod body 210 respectively, so that the block 222 drives the locking block 220 to engage in the slot 202.

[0046] It should be noted that the stop block 223 is coaxially disposed on the end face of the shaft post 221 away from the square block 222. The elastic element 23 is a spring structure, sleeved on the shaft post 221, and located on the side of the first protrusion 211 away from the square block 222. The two ends of the elastic element 23 abut against the stop block 223 and the first protrusion 211, respectively. Under the action of the elastic element 23, the elastic element 23 pushes the stop block 223 to drive the shaft post 221 to extend towards the side of the first protrusion 211 away from the slot 202, so that the shaft post 221 drives the locking block 220 disposed on the square block 222 to engage in any slot 202, thereby preventing the first protrusion 211 from continuing to slide in the sliding hole 201, thus making the angle between the back frame 20 and one side of the housing 10 adjustable.

[0047] like Figures 1 to 4 , Figure 6 , Figure 8 As shown, in one embodiment, the locking block 22 further includes a cone cap 224, which is disposed on the shaft post 221 and is located on the side of the block 222 away from the stop block 223.

[0048] It should be noted that when the angle between the back frame 20 and one side of the housing 10 needs to be adjusted, by pulling the cone cap 224, the shaft 221 extends relative to the first protrusion 211 towards the slot 202, while simultaneously causing the stop block 223 to press against the elastic element 23. This causes the block 222 to disengage the locking block 220 from the slot 202, allowing the first protrusion 211 to drive the shaft 221. After the first protrusion 211 drives the shaft 221 to slide to any position within the sliding hole 201 to adjust the angle between the back frame 20 and one side of the housing 10, the cone cap 224 is released. This allows the elastic element 23 to push the stop block 223, which in turn causes the locking block 220 on the block 222 to engage with the corresponding slot 202 via the shaft 221, preventing the first protrusion 211 from sliding relative to the sliding hole 201. This is how the angle between the back frame 20 and one side of the housing 10 is adjusted.

[0049] like Figures 1 to 2 , Figure 4 As shown, in one embodiment, the sliding hole 201, the slot 202, the support rod 21, and the locking block 22 together form an adjusting member.

[0050] It should be noted that an adjusting component is provided on both sides of the back frame 20, and two bearing seats are provided. The two ends of one bearing seat are rotatably connected to one side of the back frame 20 and an adjusting component, respectively. Furthermore, the two adjusting components together adjust the angle between the back frame 20 and one side of the housing 10.

[0051] like Figures 1 to 2 , Figures 4 to 5 As shown, in one embodiment, the back frame 20 has a plurality of screw holes for fixing to the wall, and there is a gap between each screw hole.

[0052] It should be noted that the back frame 20 can be fixed to the wall with screws. When the back frame 20 and the box 10 form an angle, the box 10 is positioned relative to the wall.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
