Description

Technical Field

[0001] This invention relates to a wall-mountable communication device speaker and its mounting method, belonging to the technical field of communication device speakers. Background Technology

[0002] Currently, when wall-mounting communication equipment speakers, fixed brackets or simple L-shaped hangers are mainly used to fix the speaker body to the wall.

[0003] Such installation structures generally have the following shortcomings: First, the installation and disassembly process is cumbersome, usually requiring the use of special tools such as screwdrivers for tightening or loosening, which is not conducive to the daily maintenance, position adjustment, or temporary removal of the speakers; Second, the brackets are mostly designed with a fixed angle, making it difficult to adjust the orientation and tilt angle of the speakers after installation, and making it impossible to flexibly adjust the sound wave coverage direction according to the actual listening area of ​​the conference room or public space; Third, some wall-mounted speakers have too small a gap between themselves and the wall, which greatly reduces the effectiveness of the phase guidance technology that relies on wall reflection to achieve virtual surround sound, resulting in muffled sound and a narrow sound field, affecting speech clarity and listening experience. Therefore, there is an urgent need to improve a wall-mountable communication equipment speaker and its mounting method to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wall-mountable communication device speaker and its mounting method, so as to solve the problems of inconvenient installation and maintenance, difficulty in angle adjustment, and easy loosening after long-term use in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wall-mountable communication device speaker and its mounting method are disclosed. The speaker body comprises a main body and a connector installed at the lower center of the main body. The connector is fixedly connected to the lower end of the main body, and a plug-in component is installed inside the lower end of the connector. The connector includes a T-shaped fixing shell with a blind hole in the center, and an annular anti-slip sleeve fixedly connected inside the blind hole. The plug-in component includes a plug post with a threaded rod fixedly connected to its top. A positioning component is installed at the lower end of the threaded rod, and annularly spaced positioning plates are installed on the outer side of the positioning component. Locking components are installed on the outer sides of each positioning plate, and a rubber post is fixedly connected to the end of each positioning plate away from the center point of the plug post. The locking component includes a C-shaped plate with an anti-slip pad fixedly connected to its upper end, a connecting shaft fixedly connected to the middle of the C-shaped plate, and a spring-loaded mechanism installed in the middle of the connecting shaft.

[0007] Furthermore, the plug-in post includes a post shell, and the upper and lower ends of the post shell are provided with through holes for limiting the C-shaped plate. A limiting shell is provided between the upper and lower through holes, and the limiting shell is fixedly connected to the inner wall of the post shell. The rubber post is disposed inside the limiting shell.

[0008] Furthermore, the positioning plate includes a plate body, one end of which is slidably connected to the inside of the limiting shell, the other end of which is set with an inclined surface, and a cross hole with a cross-shaped cross-section is opened in the middle of the plate body.

[0009] Furthermore, in the initial state, the upper end of the C-shaped plate is hidden inside the upper through hole, and the lower end of the C-shaped plate is exposed outside the lower through hole. The connecting shaft is rotatably connected to the plate body through the cross hole, and the spring is set in the middle inside the cross hole.

[0010] Furthermore, the positioning component includes a positioning shaft, a hexagonal prism is fixedly connected to the lower end of the positioning shaft, and a conical block is fixedly connected to the upper end of the positioning shaft. A threaded hole is opened on the inner side of the upper end of the conical block.

[0011] Furthermore, the conical block has a trapezoidal cross-section, and the conical block is spirally connected to the threaded rod through a threaded hole in the middle of the upper end. The threaded rod, the conical block, and the cylindrical shell are coaxially arranged.

[0012] Furthermore, the connector is fixedly connected to the upper end of the angle adjustment assembly, the angle adjustment assembly is installed at the top of the moving end of the telescopic rod, the fixed end of the telescopic rod is fixedly connected to the fixing block by connecting bolts, the other end of the fixing block is welded and fixed with a fixing plate, the four corners of the fixing plate are provided with round holes for the installation of expansion bolts, and a protective cover is installed on the outside of the fixing plate.

[0013] Furthermore, the angle adjustment component includes a rotating component with a through hole in the middle of its upper end, a rotating shaft fixedly connected to the lower end of the rotating component for rotatably connecting with the telescopic rod, and an arc-shaped adjustment groove at the bottom end of the rotating component, with a locking bolt installed inside the adjustment groove.

[0014] Furthermore, the lateral projection of the rotating component is U-shaped, the locking bolt installed inside the adjusting groove is spirally connected to the telescopic rod, a positioning shaft is placed inside the perforation, and a hexagonal prism fixedly connected to the lower end of the positioning shaft is located at the lower end of the perforation.

[0015] Furthermore, it includes the following steps:

[0016] Step 1: Based on the installation location of the communication equipment speaker, measure and determine the installation position of the fixing plate. After determination, position the fixing plate using expansion bolts.

[0017] Step 2: After the fixing plate is fixed, install the protective cover on the outside of the fixing plate to cover the expansion bolts used to fix the fixing plate, and then fix the fixing block and the telescopic rod together with the connecting bolts;

[0018] During the process of fixing the telescopic pole, the lateral angle adjustment of the subsequent communication equipment speaker installation can be achieved by adjusting the angle between the telescopic pole and the front face of the fixing plate.

[0019] Step 3: After installation, adjust the angle of the rotating part and the plug according to the required vertical installation angle of the communication equipment speaker. The adjustment is achieved by adjusting the angle of the rotating part. After adjustment, tighten one side of the rotating part with the locking bolt to achieve positioning.

[0020] Step 4: After adjusting the plug angle, place the speaker body of the communication equipment directly on the outside of the plug using the connector. During placement, the angle of the speaker body can be adjusted according to the actual required angle.

[0021] After installation, the lower end of the fixed shell will press against the lower end of the C-shaped plate. After the lower end of the C-shaped plate is pressed, the lower end of the C-shaped plate moves around the center point of the lower end of the connecting axial column shell, and the upper end of the C-shaped plate moves away from the center point around the upper end of the connecting axial column shell, and drives the anti-slip pad to stick tightly to the annular anti-slip sleeve, thus completing the locking.

[0022] Step 5: When it is necessary to remove the speaker body of the communication equipment, the hexagonal prism and positioning shaft drive the conical block to rotate and move it downward. At this time, under the action of the rubber column, the C-shaped plate moves into the column shell as a whole, so that the anti-slip pad and the ring anti-slip sleeve are separated. After separation, the speaker body of the communication equipment can be directly removed from the connector.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention achieves quick, tool-free assembly and disassembly of the speaker body by using the interlocking of the connector and the plug-in component, and the linkage structure of the C-shaped plate, anti-slip pad, and spring in the locking component. During installation, simply place the speaker downwards; the lower end of the C-shaped plate is pressed and rotates around the connecting shaft, causing the anti-slip pad to press against the annular anti-slip sleeve to automatically lock. During disassembly, simply operate the positioning component to release the lock, greatly improving installation and maintenance efficiency. At the same time, the tight fit between the annular anti-slip sleeve and the anti-slip pad provides reliable vibration and anti-loosening performance, effectively avoiding the risk of the speaker loosening or falling due to long-term vibration.

[0025] 2. This invention achieves multi-dimensional flexible adjustment of the speaker's horizontal and vertical pitch angles through the integrated design of the angle adjustment component, telescopic rod, and fixing block. The rotating part, together with the rotating shaft, arc-shaped adjustment groove, and locking bolt, can achieve stepless adjustment and locking of the vertical angle, while the connecting bolt allows for horizontal swing adjustment. The telescopic rod further provides the ability to adjust the front and rear distances.

[0026] 3. This invention can precisely adjust the coverage direction according to the actual sound field requirements of the conference room or public space, ensuring that the sound waves are directed to the target listening area. At the same time, through the rotatable fit between the speaker body and the connector, circumferential fine-tuning can still be performed after installation, which is convenient for optimizing the sound propagation path according to the environment.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1-11 As shown in the figure, this embodiment provides a wall-mountable communication device speaker, including a communication device speaker body 1 and a connector 2 installed in the middle of the lower end of the communication device speaker body 1. The connector 2 is fixedly connected to the lower end of the communication device speaker body 1, and a plug-in 9 is installed inside the lower end of the connector 2. The connector 2 includes a T-shaped fixing shell 21, with a blind hole 22 in the middle of the fixing shell 21, and an annular anti-slip sleeve 23 fixedly connected inside the blind hole 22. The plug-in 9 includes a plug post 91, and the top of the plug post 91 is fixed inside the... A threaded rod 96 is fixedly connected, and a positioning component 95 is installed at the lower end of the threaded rod 96. A ring of equally spaced positioning plates 92 are installed on the outside of the positioning component 95. Locking parts 94 are installed on the outside of each positioning plate 92. A rubber post 93 is fixedly connected to the end of the positioning plate 92 away from the center point of the insertion post 91. The locking part 94 includes a C-shaped plate 941. An anti-slip pad 942 is fixedly connected to the upper end of the C-shaped plate 941. A connecting shaft 943 is fixedly connected to the middle of the C-shaped plate 941. A spring 944 is installed in the middle of the connecting shaft 943.

[0041] Through the above technical solution, the lower end of the speaker body 1 of the communication equipment is fixedly connected to the connector 2, and the connector 2 is provided with an annular anti-slip sleeve 23. The top end of the plug post 91 of the plug-in component 9 is fixed with a threaded rod 96, and the lower end of the threaded rod 96 is installed with a positioning component 95. The outer side of the positioning component 95 is provided with annularly distributed positioning plates 92. Locking components 94 are installed on the outer side of the positioning plates 92, and rubber posts 93 are fixed at the ends of the positioning plates 92. The locking components 94 include a C-shaped plate 941, an anti-slip pad 942, a connecting shaft 943, and a spring. 944. During installation, connector 2 is inserted into plug connector 9. The lower end of the fixing shell 21 presses against the lower end of C-shaped plate 941, forcing C-shaped plate 941 to rotate around connecting shaft 943. Its upper end drives anti-slip pad 942 to press against the annular anti-slip sleeve 23 outward, achieving quick self-locking fixation without additional tools. When disassembling, only the positioning component 95 needs to be operated to release the lock, which greatly improves the convenience and reliability of speaker wall-mounting installation and maintenance. At the same time, the cooperation between the annular anti-slip sleeve 23 and the anti-slip pad 942 ensures the anti-vibration and anti-loosening performance during long-term use.

[0042] In one possible embodiment, the internal structure and linkage mechanism of the connector are further refined: the connector 91 includes a shell 911, a through hole 912, and a limiting shell 913, with the rubber column 93 disposed inside the limiting shell 913; one end of the plate body 921 of the positioning plate 92 is slidably connected to the limiting shell 913, and the other end is inclined and has a cross hole 922; the C-shaped plate 941 is initially hidden in the upper through hole 912 and exposed outside the lower through hole 912, with the connecting shaft 943 rotatably connected through the cross hole 922, and the spring 944 is placed in the middle of the cross hole 922; the positioning assembly 95 includes a positioning shaft 951, a hexagonal prism 954, a conical block 952, and a threaded hole 953, with the conical block 952 coaxially connected through a threaded rod 96;

[0043] The above structure enables precise linkage between the retraction and extension of the locking component 94 and the axial movement of the positioning component 95. When the conical block 952 moves upward, its conical surface pushes the plate 921 to slide outward radially, causing the lower end of the C-shaped plate 941 to be exposed and locked. When the conical block 952 moves downward, the elasticity of the rubber column 93 causes the plate 921 to reset, and the C-shaped plate 941 retracts as a whole, unlocking cleanly and crisply. This design not only realizes the rapid switching between locking and unlocking, but also ensures that the C-shaped plate 941 rotates smoothly and is evenly stressed through the cooperation between the cross hole 922 and the connecting shaft 943, effectively avoiding jamming or uneven wear, and significantly improving the durability and operation feel of the plug-in mechanism.

[0044] Specifically: the insertion post 91 includes a post housing 911, with through holes 912 at both the upper and lower ends for limiting the C-shaped plate 941. A limiting shell 913 is provided between the upper and lower through holes 912, and the limiting shell 913 is fixedly connected to the inner wall of the post housing 911. The rubber post 93 is disposed inside the limiting shell 913. The positioning plate 92 includes a plate body 921, one end of which is slidably connected inside the limiting shell 913, and the other end of which is inclined. A cross hole 922 with a cross-shaped cross-section is provided in the middle of the plate body 921. In the initial state, the upper end of the C-shaped plate 941 is hidden inside the upper through hole 912. In its initial state, the upper end of the 41 is exposed outside the lower through hole 912. The connecting shaft 943 is rotatably connected to the plate 921 through the cross hole 922. The spring 944 is set in the middle of the cross hole 922. The positioning assembly 95 includes a positioning shaft 951. A hexagonal prism 954 is fixedly connected to the lower end of the positioning shaft 951. A conical block 952 is fixedly connected to the upper end of the positioning shaft 951. A threaded hole 953 is opened on the inner side of the upper end of the conical block 952. The cross section of the conical block 952 is trapezoidal. The conical block 952 is spirally connected to the threaded rod 96 through the threaded hole 953 opened in the middle of the upper end. The threaded rod 96, the conical block 952 and the cylindrical shell 911 are coaxially arranged.

[0045] In one possible embodiment, a complete wall-mounted installation adjustment assembly is constructed: the plug-in 9 is fixedly connected to the upper end of the angle adjustment component 4, the angle adjustment component 4 is installed on the top of the moving end of the telescopic rod 3, the fixed end of the telescopic rod 3 is fixed to the fixing block 5 by the connecting bolt 6, the fixing block 5 is welded to the fixing plate 8, the fixing plate 8 has round holes at the four corners and a protective cover 7 is installed on the outside; the angle adjustment component 4 includes a rotating part 41, a through hole 42, a rotating shaft 43, an arc-shaped adjustment groove 44 and a locking bolt 45, and the rotating part 41 is U-shaped, the positioning shaft 951 is placed in the through hole 42, and the hexagonal prism 954 at its lower end is placed at the lower end of the through hole 42;

[0046] This assembly offers multi-dimensional adjustment capabilities: the front-to-back distance of the speaker can be adjusted via the telescopic rod 3; the vertical tilt angle of the speaker can be infinitely adjusted and locked by the swaying of the rotating part 41 around the pivot 43 and the combination of the adjustment groove 44 and the locking bolt 45; at the same time, the connecting bolt 6 between the fixing plate 8 and the telescopic rod 3 allows for horizontal angle adjustment, while the protective cover 7 effectively covers the mounting bolts of the fixing plate 8, improving the overall aesthetics and preventing dust and rust. The above structure enables the communication equipment speaker to flexibly adapt to the wall conditions of different conference rooms or public spaces, ensuring precise and controllable sound wave coverage direction, thus providing a hardware foundation for optimizing the listening area and reducing wall reflection interference.

[0047] Specifically: the connector 9 is fixedly connected to the upper end of the angle adjustment assembly 4. The angle adjustment assembly 4 is installed at the top of the moving end of the telescopic rod 3. The fixed end of the telescopic rod 3 is fixedly connected to the fixing block 5 through the connecting bolt 6. The other end of the fixing block 5 is welded and fixed with a fixing plate 8. The four corners of the fixing plate 8 are provided with round holes for the installation of expansion bolts. A protective cover 7 is installed on the outside of the fixing plate 8. The angle adjustment assembly 4 includes a rotating part 41. The upper middle of the rotating part 41 is provided with a through hole 42. The lower end of the rotating part 41 is fixedly connected with a rotating shaft 43 for rotating connection with the telescopic rod 3. The bottom end of the rotating part 41 is provided with an arc-shaped adjustment groove 44. A locking bolt 45 is installed inside the adjustment groove 44. The lateral projection of the rotating part 41 is U-shaped. The locking bolt 45 installed inside the adjustment groove 44 is spirally connected to the telescopic rod 3. A positioning shaft 951 is placed inside the through hole 42. A hexagonal prism 954 is fixedly connected to the lower end of the positioning shaft 951 at the lower end of the through hole 42.

[0048] like Figures 1-11 As shown in this embodiment, the principle of a wall-mountable communication device speaker mounting method is as follows:

[0049] The steps include the following:

[0050] Step 1: Based on the installation location of the communication equipment speaker, measure and determine the installation position of the mounting plate 8. After determination, use expansion bolts to position the mounting plate 8 and fix it in place.

[0051] Step 2: After the fixing plate 8 is fixed, the protective cover 7 is installed on the outside of the fixing plate 8 to cover the expansion bolts used to fix the fixing plate 8. Then, the fixing block 5 and the telescopic rod 3 are fixed together by the connecting bolts 6.

[0052] During the process of fixing the telescopic rod 3, the angle between the telescopic rod 3 and the front end face of the fixing plate 8 can be adjusted to achieve the horizontal angle adjustment of the subsequent communication equipment speaker installation. The protective cover 7 is installed and the telescopic rod 3 is fixed by the connecting bolts 6, while the horizontal angle is adjusted at the same time.

[0053] Step 3: After installation, adjust the angle of the rotating part 41 and the plug post 91 according to the vertical installation angle requirements of the communication equipment speaker. The adjustment is achieved by adjusting the angle of the rotating part 41. After adjustment, the locking bolt 45 is used to press one side of the rotating part 41 to achieve positioning. The vertical angle adjustment and locking are achieved by the rotating part 41 and the locking bolt 45.

[0054] Step 4: After adjusting the angle of the plug 91, place the speaker body 1 of the communication equipment directly on the outside of the plug 91 through the connector 2. During the placement process, the angle of the speaker body 1 of the communication equipment can be adjusted according to the actual required angle.

[0055] After installation, the lower end of the fixed shell 21 will press against the lower end of the C-shaped plate 941. After the lower end of the C-shaped plate 941 is pressed, the lower end of the C-shaped plate 941 moves around the connecting shaft 943 toward the center point of the lower end of the column shell 911. The upper end of the C-shaped plate 941 moves around the connecting shaft 943 toward the upper end of the column shell 11 away from the center point, and drives the anti-slip pad 942 to stick tightly to the annular anti-slip sleeve 23, thus completing the locking. The speaker body 1 of the communication equipment is placed directly on the outside of the plug-in 9 through the connector 2. The lower end of the fixed shell 21 presses against the C-shaped plate 941 to achieve automatic locking. During the installation process, the speaker body 1 can be rotated to adjust its orientation angle as needed.

[0056] Step 5: When it is necessary to remove the speaker body 1 of the communication equipment, the hexagonal prism 954 and the positioning shaft 951 drive the conical block 952 to rotate, causing it to move downwards. At this time, under the action of the rubber column 93, the plate 921 drives the C-shaped plate 941 to move into the column shell 911, so that the anti-slip pad 942 separates from the annular anti-slip sleeve 23. After separation, the speaker body 1 of the communication equipment can be directly removed from the connector 9. The hexagonal prism 954 drives the positioning shaft 951 and the conical block 952 to rotate and move downwards, so that the rubber column 93 pushes the plate 921 to reset, and the anti-slip pad 942 separates from the annular anti-slip sleeve 23, thus easily removing the speaker.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

The locking bolt (45) installed inside the adjusting groove (44) is spirally connected to the telescopic rod (3). The positioning shaft (951) is placed inside the through hole (42). The hexagonal prism (954) fixedly connected to the lower end of the positioning shaft (951) is located at the lower end of the through hole (42).

10. A method for mounting a wall-mountable communication device speaker according to any one of claims 1-9, characterized in that: Includes the following steps: Step 1: Based on the installation location of the communication equipment speaker, measure and determine the installation position of the fixing plate (8). After the determination is completed, position the fixing plate (8) using expansion bolts. Step 2: After the fixing plate (8) is fixed, the protective cover (7) is installed on the outside of the fixing plate (8) to cover the expansion bolts used to fix the fixing plate (8). Then, the fixing block (5) and the telescopic rod (3) are fixed together by the connecting bolts (6). During the process of fixing the telescopic rod (3), the angle between the telescopic rod (3) and the front end face of the fixing plate (8) can be adjusted to realize the lateral angle adjustment of the subsequent communication equipment speaker installation; Step 3: After installation, adjust the angle of the rotating part (41) and the plug (91) according to the vertical installation angle of the communication equipment speaker. The adjustment is achieved by adjusting the angle of the rotating part (41). After adjustment, the rotating part (41) is positioned by pressing one side of the locking bolt (45). Step 4: After the angle of the plug (91) is adjusted, place the speaker body (1) of the communication equipment directly on the outside of the plug (91) through the connector (2). During the placement process, the angle of the speaker body (1) of the communication equipment can be adjusted according to the actual required angle. After installation, the lower end of the fixed shell (21) will press against the lower end of the C-shaped plate (941). After the lower end of the C-shaped plate (941) is pressed, the lower end of the C-shaped plate (941) moves around the connecting shaft (943) toward the center point of the lower end of the column shell (911). The upper end of the C-shaped plate (941) moves around the connecting shaft (943) toward the upper end of the column shell (11) away from the center point, and drives the anti-slip pad (942) to stick tightly to the annular anti-slip sleeve (23) to complete the locking. Step 5: When it is necessary to remove the speaker body (1) of the communication equipment, the cone block (952) is rotated by the hexagonal prism (954) and the positioning shaft (951) to move downward. At this time, the plate (921) is driven by the rubber column (93) to move the C-shaped plate (941) into the column shell (911) to separate the anti-slip pad (942) from the ring anti-slip sleeve (23). After separation, the speaker body (1) of the communication equipment can be directly removed from the connector (9).
