[0023] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See Figures 1 to 3 The utility model discloses a directional warning loudspeaker, comprising: a mounting base 22 and a loudspeaker body, a positioning portion 2211 being provided on the mounting base 22, and a connecting bracket 21 being provided on the loudspeaker body, a first connecting portion 2111 and a plurality of second connecting portions 2112 being provided on the connecting bracket 21, the plurality of second connecting portions 2112 being arranged in an arc shape with the first connecting portion 2111 as the center. The first connecting portion 2111 is rotatably connected to the mounting base 22 to allow the loudspeaker body to rotate relative to the mounting base 22, and one of the second connecting portions 2112 is used to connect with the positioning portion 2211 when the loudspeaker body rotates, thereby limiting the rotational movement of the loudspeaker body and the connecting base.

[0027] Based on the above structure, during assembly, the mounting base 22 is first connected to the outside (such as the ground or a table), and then the first connecting portion 2111 on the connecting bracket 21 is rotatably connected to the mounting base 22, so that the speaker body can be relatively rotated with the mounting base 22 through the connecting bracket 21. Therefore, the angle of the speaker body can be adjusted in real time by rotating the connecting bracket 21, thereby achieving real-time adjustment of the emission direction of the sound waves of the speaker body.

[0028] Specifically, during installation, after the user rotates the speaker body to a specified angle, the positioning portion 2211 on the mounting base 22 is connected to the second connection portion 2112 on the connecting bracket 21 to limit the rotation of the speaker body, so that the speaker body is locked in the specified position; because the second connection portions 2112 are arranged in an arc shape with the first connection portion 2111 as the center, so that the multiple second connection portions 2112 are evenly arranged on the circumference, when the connecting bracket 21 is rotated relative to the mounting base 22 with the first connection portion 2111 as the center, the positioning portion 2211 on the mounting base 22 can be connected to one of the second connection portions 2112 distributed at different angles with the first connection portion 2111 as the center when the connecting bracket 21 is rotated to different angles, so that the connecting bracket 21 can be locked when it is rotated to different angles.

[0029] When the user needs to adjust the sound wave emission direction of the loudspeaker body, the positioning portion 2211 can be separated from one of the second connecting portions 2112. At this time, the loudspeaker body is rotated up and down with the first connecting portion 2111 as the center through the connecting bracket 21. When it is rotated to a specified angle, it is only necessary to reconnect the positioning portion 2211 to the corresponding second connecting portion 2112 to limit the rotation angle of the connecting bracket 21 again, so that the loudspeaker body can be fixed at the specified angle. In this way, when the user adjusts the sound wave emission direction of the loudspeaker body, there is no need to disassemble and reassemble the entire structure of the loudspeaker body, which saves time and effort.

[0030] In addition, since the first connecting portion 2111 and the second connecting portion 2112 on the connecting bracket 21 are both connected to the mounting base 22 after the loudspeaker body is rotated to a specified angle, the connection between the connecting bracket 21 and the mounting base 22 is more stable, making the supporting structure of the loudspeaker body (i.e., the connecting bracket 21 and the mounting base 22) more stable and less likely to loosen after rotation.

[0031] Specifically, the first connecting portion 2111 can be a rotating shaft or a rod-shaped structure provided on the connecting bracket 21, which can be rotated and passed through the mounting seat 22 to drive the connecting bracket 21 to rotate; of course, the first connecting portion 2111 can also be a hole or a groove body or other structure provided on the connecting bracket 21. At this time, a corresponding rotating shaft or rod-shaped structure can be provided on the mounting seat 22 to enable the two to be rotatably connected. The specific setting can be based on the actual scenario.

[0032] More specifically, the multiple second connection parts 2112 can be multiple snap-in holes or groove structures arranged with the first connection part 2111 as the center, and the positioning part 2211 can be set on the mounting seat 22 as a snap-in strip or a columnar or rod-shaped structure. The two are set correspondingly so that the two can be snap-connected or detachably connected through a connecting piece, so that the positioning part 2211 can connect or detach the corresponding second connection part 2112 in real time as the rotation angle of the connecting bracket 21 changes, and the adjustment is more time-saving and labor-saving.

[0033] Furthermore, a first connecting plate 211 is provided on the connecting bracket 21, specifically a first connecting portion 2111 and a plurality of second connecting portions 2112 are provided on the first connecting plate 211, a second connecting plate 221 is provided on the mounting seat 22, a positioning portion 2211 is provided on the second connecting plate 221, and a connecting column 2212 is also provided on the second connecting plate 221, the connecting column 2212 is spaced apart from the positioning portion 2211 in upper and lower directions, and is rotatably connected to the first connecting portion 2111, so that the first connecting plate 211 can rotate relative to the second connecting plate 221.

[0034] Specifically, during assembly, a first connecting plate 211 is provided on the connecting bracket 21 to increase the connection area of the connecting bracket 21, so that there is enough space on the connecting bracket 21 to set the first connecting part 2111 and multiple second connecting parts 2112; similarly, a second connecting plate 221 is provided on the mounting seat 22 to increase the connection area of the mounting seat 22, so that the connection area between the connecting bracket 21 and the mounting seat 22 is increased through the first connecting plate 211 and the second connecting plate 221, so that the two are more tightly connected.

[0035] During assembly, the first connecting portion 2111 is rotatably connected through the connecting column 2212, so that the first connecting plate 211 can rotate relative to the second connecting plate 221, and the first connecting plate 211 and the second connecting plate 221 are preliminarily connected. Then, when the speaker body is rotated to a specified position through the first connecting plate 211 on the connecting bracket 21, the positioning portion 2211 is connected to the corresponding second connecting plate 221 to lock the connecting bracket 21 and the mounting base 22 for the second time, making the connection between the connecting bracket 21 and the mounting base 22 more stable. In this way, the structure of the speaker body is more stable after rotation and is not easy to shake.

[0036] It should be noted that the connecting column 2212 can be directly rotated and inserted into the first through-hole, or a hole or groove can be set on the connecting column 2212, and a connecting piece can be inserted through the first through-hole to make it rotatably connected to the hole or groove on the connecting column 2212. The specific setting can be based on the needs.

[0037] Preferably, the first connecting portion 2111 in this embodiment is a first through-hole provided on the first connecting plate 211, the second connecting portion 2112 is a second through-hole provided on the first connecting plate 211, the connecting column 2212 is rotatably connected to the first through-hole, and the positioning portion 2211 is a positioning column provided on the second connecting plate 221, and the positioning column is connected to one of the second through-holes when the first connecting plate 211 rotates relative to the second connecting plate 221.

[0038] During specific installation, the second connecting plate 221 is fitted with the first connecting plate 211, and the positioning post is rotated and inserted into the first through-hole, so that the first connecting plate 211 can rotate relative to the second connecting plate 221, thereby driving the connecting bracket 21 and the loudspeaker body connected thereto to rotate. When it is rotated to the user-specified position, the positioning post is inserted into the corresponding second through-hole. Of course, a hole or groove structure can also be provided on the positioning post. When the positioning post corresponds to the second through-hole, the two can be detachably connected by a connecting piece passing through the second through-hole and extending into the positioning post.

[0039] Preferably, in this embodiment, a first connecting hole is provided on the connecting column 2212, and a second connecting hole is provided on the positioning column. During assembly, the first connecting hole is aligned with the first through-hole and is used to pass through the rotating shaft so that the connecting bracket 21 and the mounting seat 22 are rotatably connected. The second connecting hole is used to correspond to one of the second through-holes when the first connecting plate 211 rotates, and is used to pass through the connecting piece to connect the second connecting hole to the second connecting hole through the connecting piece, so that the connection between the two is more stable.

[0040] It should be noted that both the second connecting hole and the second through hole can be threaded holes, and the connecting members can be selected from existing screws or bolts to connect the two with threads, so that the first connecting plate 211 and the second connecting plate 221 can be detached and the connection is tighter and not easy to loosen, thereby preventing the loudspeaker body from loosening after rotation.

[0041] Furthermore, a first mounting plate 212 is provided on the connecting bracket 21. During assembly, the first mounting plate 212 is arranged opposite to the first connecting plate 211 and is used to connect to the loudspeaker body. A plurality of third through-holes 2121 are also provided on the first mounting plate 212 for connecting the connecting parts.

[0042] During specific installation, the first mounting plate 212 can be used to connect the loudspeaker body to increase the connection area between the connecting bracket 21 and the loudspeaker body through the first mounting plate 212, so that the connection between the two is more stable and the loudspeaker body is not easy to loosen, thereby reducing the risk of changing the direction of sound wave emission due to a change in the loose angle after installation.

[0043] More specifically, a second mounting plate 222 is also provided on the mounting base 22. During assembly, the second mounting plate 222 is arranged opposite to the second connecting plate 221. The connection area between the mounting base 22 and the external device is increased through the second mounting plate 222, and a plurality of mounting holes 2221 are provided on the second mounting plate 222 to pass through the connecting piece. After the second mounting plate 222 is connected to the outside through the connecting piece, the entire structure is more stable and not easy to loosen.

[0044] It should be noted that the third through-hole 2121 and the mounting hole 2221 can both be threaded holes, and the connecting members can also be existing screws or bolts.

[0045] Furthermore, the main body of the loudspeaker includes a horn 11, a shell 12, a transformer 13 and a transducer 14. The shell 12 has a mounting cavity. The horn 11 is connected to one end of the shell 12 away from the mounting cavity. The transformer 13 is connected to the transducer 14 and installed in the mounting cavity.

[0046] Specifically, during assembly, the transformer 13 is connected to the transducer 14 and installed in the installation cavity to protect the transformer 13 and the transducer 14 from being damaged by the external environment. The transformer 13 is then connected to the external circuit through a line, and the input alternating current is converted into a voltage and current suitable for the operation of the transducer 14 through the transformer 13. The sound waves are then generated through the transducer 14 and finally diffused to the outside through the horn 11.

[0047] More specifically, a cover plate 15 is further provided on the shell 12. After the transformer 13, the transducer 14 and the circuit are connected, the cover plate 15 is connected to the opening of the shell 12 (specifically, it can be connected by gluing or a connector) to seal the installation cavity through the cover, thereby preventing external dust from entering the installation cavity and affecting the use of the internal structure of the shell 12.

[0048] In addition, a connector 16 is provided on the housing 12. Specifically, the connector 16 can be an existing aviation plug. During assembly, the transformer 13 and the transducer 14 can be electrically connected, and then electrically connected to the connector 16 (i.e., the aviation plug). Finally, the aviation plug is used to receive data signals and connect to an external power supply to power the transformer 13 and the transducer 14.

[0049] Furthermore, a fixing member 151 is provided on the cover plate 15 . During assembly, the fixing member 151 is placed toward the installation cavity and abuts against the transformer 13 after the cover plate 15 covers the installation cavity to lock the transformer 13 .

[0050] Specifically, after the transformer 13 and the transducer 14 are installed, if they are not fixed with connecting parts, the transformer 13 may shake, affecting their use. Therefore, in this embodiment, a fixing part 151 is provided on the cover 15, and the fixing part 151 is abutted against the outer periphery of the transformer 13, so that after the cover 15 covers the installation cavity, the fixing part 151 is always abutted against the transformer 13, making the transformer 13 less likely to shake and the structure more stable.

[0051] It should be noted that the fixing member 151 may be a block or column or other structure protruding from the cover plate 15 , so that it can be pressed against the outer periphery of the transformer 13 , thereby locking the transformer 13 .

[0052] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
