[0002] A motorcycle horn is a sound device installed on a motorcycle, used to emit warning sounds to alert pedestrians or other vehicles around of the presence of the motorcycle. Its main function is to ensure enhanced safety during driving, especially in complex road traffic conditions or situations with potential dangers. The sound of the horn can effectively transmit warning information to avoid collisions or other accidents.

[0003] Existing motorcycle horns are usually directly fixed to the motorcycle by bolts, with a relatively firm structure. However, due to this design method, the angle of the horn cannot be flexibly adjusted. In this case, the following disadvantages exist: Firstly, the sound propagation direction of the horn is single and cannot be adjusted according to actual driving needs, resulting in a weakened warning effect; Secondly, the fixed angle may cause the sound to fail to effectively cover a specific area, especially in turning or narrow sections, increasing potential safety hazards; Finally, the horn sound may be reflected to the driver's ear due to a poor angle, causing noise interference and affecting the driving experience.

[0004] Therefore, those skilled in the art have provided a loudspeaker with an adjustable angle to solve the problems raised in the above background technique. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0028] Referring to Figures 1 to 5 , a horn with adjustable angle provided by the present utility model includes a horn body 1, a positioning mechanism 2 and an adjusting mechanism 3; wherein, the adjusting mechanism 3 includes a hinge seat 304, the upper end of the hinge seat 304 is fixedly connected to the lower end of the horn body 1, the lower end of the hinge seat 304 is hingedly provided with a rotating head 305, the lower end of the rotating head 305 is rotatably provided with a connecting shaft 306, the lower end of the connecting shaft 306 is fixedly connected to a mounting plate 301, a plurality of jacks 302 are annularly arranged at the edge of the upper end surface of the mounting plate 301, and a limiting hole 303 is provided on one side of the edge of the lower end surface of the rotating head 305; the positioning mechanism 2 includes a limiting block 202, a pressing spring 201 and an insertion rod 203 are respectively fixedly provided at the upper end and the lower end of the limiting block 202, the upper end of the pressing spring 201 is fixedly provided on the inner top surface of the limiting hole 303, and the lower end of the insertion rod 203 is in plug - in fit with the jack 302.

[0029] Specifically, in the design of the positioning mechanism 2, the cooperation of the limit block 202, the pressing spring 201 and the insertion rod 203 is the core of the speaker. The existence of the pressing spring 201 enables the limit block 202 to generate a predetermined pressure within a certain range, and this pressure can make the insertion rod 203 automatically reset or stay in an appropriate fixed position after adjustment. The ingenious difference in the sizes of the insertion rod 203 and the insertion hole 302 can ensure that the insertion rod 203 can freely insert into the insertion hole 302 without jamming, and at the same time will not become loose or slip off due to vibration or external force during use. The design of this positioning mechanism 2 enables the speaker to stably maintain the preset position at different usage angles. The resilience provided by the pressing spring 201 can ensure that the insertion rod 203 can return to the set fixed state after adjustment, and the limit block 202 can ensure that the insertion rod 203 has a stable fixing effect when inserted into the insertion hole 302. This design prevents the angle of the speaker from changing due to external vibration or accidental touch during use, ensuring the safety and durability of the speaker angle adjustment. The overall structural design provides users with a stable, durable and easy-to-adjust experience, while ensuring the reliability of the device during long-term use.

[0030] Specifically, the structural design of the adjustment mechanism 3 is very complex and precise. The combination of the hinge seat 304, the rotating head 305 and the connecting shaft 306 constitutes a multi-degree-of-freedom adjustment system. The hinged manner of the hinge seat 304 and the rotating head 305 enables the speaker body 1 to rotate around a specific axis, and the rotational design of the rotating head 305 and the connecting shaft 306 can make the direction adjustment of the speaker body 1 more diversified. The fixed design of the mounting plate 301 and the connecting shaft 306 ensures that the speaker body 1 can be firmly mounted after adjustment, and the several insertion holes 302 arranged in a ring shape at the edge of the mounting plate 301 provide additional fixing options for the speaker body 1, further enhancing the flexibility of the installation of the speaker body 1. The limit hole 303 is located on the lower end surface of the rotating head 305 and can limit the excessive movement of the insertion rod 203, ensuring that the entire adjustment system will not be displaced during use. This design allows the speaker body 1 to be adjusted at various angles and directions, greatly improving the adaptability and operability of the product. Through the flexible connection of the hinge seat 304 and the rotating head 305, users can accurately adjust the angle of the speaker body 1 according to needs to ensure that the sound effect is transmitted to the required direction. At the same time, the fixed design of the connecting shaft 306 and the mounting plate 301 ensures that the speaker body 1 can be firmly mounted on the bracket or wall after adjustment and will not be displaced or loosened due to gravity or external force. The existence of the limit hole 303 ensures the stability of the insertion rod 203 during the adjustment process, enabling the speaker body 1 to still maintain accurate positioning after multiple adjustments.

[0031] Refer to Figures 1 to 5, a handle 204 is fixedly sleeved on the lower end of the rod body of the insertion rod 203, which facilitates the control of the insertion rod 203 through the handle 204. The size of the insertion rod 203 is smaller than that of the insertion hole 302, and the size of the lower end outlet of the limit hole 303 is the same as that of the insertion hole 302. The limit hole 303 is set as an inverted convex shape, and the pressing spring 201 and the limit block 202 are both located at the upper part inside the limit hole 303. The size of the limit block 202 is larger than the size of the lower end outlet of the limit hole 303. A damping force is provided at the hinge joint between the hinge seat 304 and the rotating head 305. A plurality of mounting holes 307 are provided on one side of the mounting plate 301.

[0032] Specifically, the combination of the insertion rod 203, the pressing spring 201 and the limit block 202 enables the overall device to have high flexibility in terms of fixing and releasing. The size of the insertion rod 203 is designed to be slightly smaller than that of the insertion hole 302. This design can ensure that the insertion rod 203 can be smoothly inserted into the insertion hole 302 without jamming or being too tight, and at the same time, it avoids the shaking of the insertion rod 203 due to being too loose during use. The inverted convex shape design of the limit hole 303 effectively prevents the insertion rod 203 from accidentally coming out, and the limit block 202 provides additional supporting force when the insertion rod 203 is inserted into the limit hole 303. The pressing spring 201 is installed on the inner top surface of the limit hole 303, which plays an automatic pressing role, enabling the insertion rod 203 to be firmly fixed in the limit hole 303 and maintaining a certain elastic rebound effect. This design realizes the functions of quick installation and disassembly, while ensuring the stability after installation. When the user needs to adjust the angle of the speaker or disassemble the device, they only need to simply operate the insertion rod 203, which is simple and efficient. In addition, through the action of the limit block 202 and the pressing spring 201, the speaker can maintain sufficient fastening force after being fixed, preventing the speaker from loosening due to vibration or the force during use. The inverted convex shape structure of the limit hole 303 can also prevent the insertion rod 203 from accidentally sliding out under the influence of external forces, ensuring the stability of the speaker. The entire system improves the operation convenience of the user, while enhancing the safety and durability of the device, ensuring that it can still maintain stable performance during long-term use.

[0033] Working principle: During use, the angle of the speaker body 1 can be adjusted through the hinge between the hinge seat 304 and the rotating head 305. At the same time, through the rotation setting between the rotating head 305 and the connecting shaft 306, the rotation adjustment of the speaker body 1 can be realized. During the rotation adjustment process, through the pressure of the pressing spring 201 pressing down, the insertion rod 203 can be inserted into the corresponding insertion hole 302 to achieve the positioning function. Finally, the mounting holes 307 cooperate with bolts to be connected to the motorcycle.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
