Technical Field

[0001] This utility model relates to the field of truck horn technology, specifically to a high- and low-frequency combined truck super loud horn. Background Technology

[0002] As people's living standards continue to improve, higher demands are being placed on the performance of speakers. For example, some car speakers are often equipped with more functions in order to enhance driving pleasure while increasing the vehicle's luxury and comfort.

[0003] A search revealed that patent application CN202420492047.3 discloses a vehicle-mounted lifting speaker. This device, through the cooperation of a motor and a lifting platform, reduces the overall lateral size of the speaker, facilitating its placement within a vehicle. While this device optimizes space utilization through its motor and lifting platform structure, it has some significant shortcomings. It primarily addresses the spatial arrangement of the speaker, lacking an effective design for ensuring the speaker's stability. During vehicle operation, especially in vehicles with complex driving conditions like trucks, this lifting structure alone cannot guarantee stable speaker operation under vibration, and it struggles to meet the diverse sound requirements of various scenarios. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high- and low-frequency combined truck loud horn, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A high- and low-frequency combined truck loudspeaker, including a mounting base in which the speaker body is installed;

[0007] The fixing base is provided with a fixing post, and a rubber frustum is bonded to the outside of the fixing post. The horn body is provided with fixing holes around its perimeter. The fixing holes of the horn body are pressed onto the fixing post by the rubber frustum, and the rubber frustum has a fixing hole. A bolt is inserted into the fixing hole. The bolt passes through the rubber frustum and is threaded to the fixing post of the fixing base. By pressing the rubber frustum with the bolt, the rubber frustum expands and deforms, further pressing and fixing the horn body.

[0008] Multiple fixing seats are connected and fixed by a connector. A first magnet is embedded on the outer side of the fixing seat. The connector has a groove, and a second magnet is embedded in the groove. The fixing seat is attracted and fixed in the groove of the connector by the cooperation of the first magnet and the second magnet.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the back of the fixing base is provided with an insertion hole, and the connector is provided with an insertion rod. After the connector is inserted and fixed to the fixing base, the insertion rod is attracted by the second magnet and the first magnet, and the fixing base is further pressed and fixed by the insertion rod.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The engagement of the plug and socket, after the initial magnetic attraction between the mounting base and the connector, provides an additional mechanical fastening method, enhancing the stability of the connection. The attraction of the plug to the second and first magnets further improves the reliability of the plug's fastening. This design not only prevents the mounting base from loosening due to vibrations during vehicle operation, but also significantly improves the overall stability of the horn assembly structure compared to a single connection method, ensuring the horn system continues to function normally under complex operating conditions.

[0013] Furthermore, a cable inlet is provided on the back of the mounting base, through which the cable of the speaker body passes to connect to an external circuit.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The cable inlet design makes cable connections more standardized and neat, avoiding tangled cables and reducing the risk of wear, short circuits, and other malfunctions caused by cable entanglement. At the same time, the inlet protects the cables from damage caused by external factors such as dust and moisture generated during vehicle operation, ensuring a stable and reliable current transmission from the external circuit to the horn body, providing a continuous and stable power supply for the horn's normal operation.

[0016] Furthermore, the speaker body is a tweeter unit or a woofer unit.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] This design allows the combined tweeter and woofer truck loudspeaker to meet diverse sound output needs. The tweeter unit produces clear, sharp high-frequency sounds, offering advantages in long-distance warning and penetrating noisy environments; the woofer unit emits deep, powerful low-frequency sounds, enhancing the sound's weight and intimidation. Users can flexibly choose to install either the tweeter or woofer unit, or use them in combination, depending on the actual usage scenario, such as in urban roads, highways, or construction sites, to achieve the best sound effect.

[0019] Furthermore, a sound-insulating rubber pad is provided on the side of the mounting base near the sound-emitting end of the speaker body.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] Sound-absorbing rubber pads offer excellent sound insulation and vibration damping properties. When the speaker is producing sound, the rubber pads effectively absorb and block the vibrations generated by the speaker, reducing the transmission of vibrations to the mounting bracket and other components, thus minimizing component loosening and noise interference caused by vibration. Simultaneously, the sound-absorbing rubber pads also provide a degree of cushioning and protection for the speaker itself, preventing damage from prolonged vibration, extending the speaker's lifespan, and ensuring clearer, purer sound, thereby improving the speaker's sound quality.

[0022] Furthermore, the fixing base is prismatic, and the inner contour of the groove of the connector precisely matches the outer shape of the fixing base.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The prismatic mounting base and precisely matched grooves enable accurate positioning and installation. During installation, workers can quickly and accurately install the mounting base onto the connector, improving installation efficiency. The precisely matched shape also ensures a tighter contact between the mounting base and the connector, increasing friction and further enhancing connection stability. Furthermore, this design helps ensure the speaker is in the correct position and angle after installation, guaranteeing the directionality and effectiveness of sound propagation, thereby improving the overall performance of the speaker system.

[0025] This utility model provides a high- and low-frequency combined truck loudspeaker. It has the following beneficial effects:

[0026] The mounting bracket has a sound-insulating rubber pad on the side near the speaker's sound-producing end. This effectively reduces the transmission of vibrations generated during speaker operation to other components, lowering noise interference and protecting the speaker itself, thus extending its lifespan. A rubber truncated cone is bonded to the outside of the mounting post. When the speaker body is secured by bolts pressing and deforming this cone, it acts as a shock absorber, further reducing the impact of speaker vibrations on surrounding components.

[0027] The speaker body is secured to the rubber frustum and mounting post via mounting holes and bolts. This installation method is simple and convenient, facilitating installation and disassembly by workers and aiding in future maintenance and replacement of the speaker body. The mounting base and connectors employ a combination of methods, such as the mutual attraction between the first and second magnets and the insertion of the plug rod into the socket, making the connection between the mounting base and connectors more stable and reliable. This also facilitates quick assembly and improves installation efficiency.

[0028] The mounting base is prismatic, and the inner contour of the groove of the connector precisely matches the outer shape of the mounting base. This ensures that the mounting base is accurately positioned when installed on the connector, guaranteeing the installation accuracy of the entire speaker system. It also facilitates the coordinated work between the high and low frequency speakers, improving sound quality.

[0029] The back of the mounting bracket has a through-hole for cable entry. The speaker's cable is connected to the external circuit through the cable entry. This design makes the cable connection more standardized and neat, facilitates wiring and management, and effectively protects the cable from interference and damage from external factors, ensuring the stability and reliability of the speaker's electrical connection.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1: A high-low frequency combination truck horn includes a mounting base 2, within which a horn body 3 is installed. A sound-insulating rubber pad is provided on the side of the mounting base 2 near the sound-emitting end of the horn body 3. This rubber pad has excellent sound insulation and vibration damping properties. When the horn body 3 emits sound, the rubber pad effectively absorbs and blocks the vibrations generated by the horn, reducing the transmission of vibrations to the mounting base 2 and other components, thus reducing component loosening and noise interference caused by vibration. Simultaneously, the sound-insulating rubber pad also provides a certain degree of buffering protection for the horn body 3, preventing damage from prolonged vibration, extending the horn's lifespan, and ensuring a clearer and purer sound, thus improving the horn's sound quality. The horn body 3 can be either a tweeter unit or a woofer unit. This design allows the high-low frequency combination truck horn to meet different sound output requirements. The tweeter unit can produce clear, sharp high-frequency sounds, offering advantages in long-distance warning and penetrating noisy environments; the woofer unit can produce deep, powerful low-frequency sounds, enhancing the sound's weight and intimidation. Users can flexibly choose to install tweeter or woofer units, or use them in combination, according to different environments such as urban roads, highways or construction sites, to achieve the best sound effect. The back of the mounting bracket 2 has a through-hole 205. The cable of the speaker body 3 passes through the through-hole 205 to connect to the external circuit. The setting of the through-hole 205 makes the cable connection more standardized and neat, avoids the cable mess and tangles, and reduces the risk of wear, short circuit and other failures caused by the cable tangling. Meanwhile, the inlet 205 protects the cable from damage caused by external factors such as dust and moisture generated during vehicle operation, thus ensuring that the current can be transmitted stably and reliably from the external circuit to the horn body 3, providing a continuous and stable power supply for the normal operation of the horn. The mounting base 2 is equipped with a mounting post, and a rubber frustum 203 is bonded to the outside of the mounting post. The horn body 3 is provided with mounting holes around its perimeter. The mounting holes of the horn body 3 are pressed onto the mounting post by the rubber frustum 203, and the rubber frustum 203 is provided with mounting holes 202. A bolt is inserted into the mounting hole 202. The bolt passes through the rubber frustum 203 and is threadedly connected to the mounting post of the mounting base 2. By pressing the rubber frustum 203 with the bolt, the rubber frustum 203 expands and deforms, further pressing and fixing the horn body 3.

[0040] Example 2: To ensure a secure connection between the fixing base 2 and the connector 1, for example, such as Figures 1 to 3As shown, this utility model also includes: multiple fixing seats 2 connected and fixed by connectors 1. A first magnet 201 is embedded in the outer side of each fixing seat 2. The connector 1 has a groove 102. The fixing seat 2 is prismatic in shape, and the inner contour of the groove 102 in the connector 1 precisely matches the outer shape of the fixing seat 2. The prismatic fixing seat 2 and the precisely matched groove 102 enable precise positioning and installation. During installation, workers can quickly and accurately install the fixing seat 2 onto the connector 1, improving installation efficiency. The precisely matched shape also makes the contact between the fixing seat 2 and the connector 1 tighter, increasing the friction between them and further enhancing the stability of the connection. Furthermore, this design helps ensure that the speaker is in the correct position and angle after installation, guaranteeing the directionality and effectiveness of the speaker's sound propagation, thereby improving the performance of the entire speaker system. A second magnet 103 is embedded in the groove 102. The mounting base 2 is attracted and fixed to the groove 102 of the connector 1 by the interaction of the first magnet 201 and the second magnet 103. An insertion hole 204 is provided on the back of the mounting base 2. An insertion rod 101 is provided on the connector 1. After the connector 1 is inserted and fixed to the mounting base 2, the insertion rod 101 is attracted by the second magnet 103 and the first magnet 201. The insertion rod 101 further presses and fixes the mounting base 2. The cooperation between the insertion rod 101 and the insertion hole 204 provides an additional mechanical fastening method after the mounting base 2 and connector 1 are initially attracted by the magnets, enhancing the stability of the connection. The attraction of the insertion rod 101 by the second magnet 103 and the first magnet 201 further improves the reliability of the insertion rod 101's fastening. This design not only prevents the mounting bracket 2 from loosening due to vibration and other factors during vehicle operation, but also greatly improves the stability of the entire horn assembly structure compared to a single connection method, ensuring that the horn system can still work normally under complex operating conditions.

[0041] Working principle:

[0042] First, align the speaker body 3 with the fixing post on the mounting base 2 that has a rubber frustum 203, and press the fixing hole 202 of the speaker body 3 onto the rubber frustum 203. This step utilizes the flexibility of the rubber frustum 203 to provide initial positioning and cushioning during subsequent installation. Next, insert a bolt into the fixing hole 202 of the rubber frustum 203, and rotate the bolt to connect it to the threaded connection of the fixing post on the mounting base 2. The working principle is that the compressive force generated when the bolt is tightened causes the rubber frustum 203 to expand and deform due to the compression. Because rubber has good elasticity, the deformed rubber frustum 203 will tightly press against the speaker body 3, thereby achieving a firm fixation of the speaker body 3 and ensuring that the speaker will not shift due to vibration during operation.

[0043] The mounting base 2 is prismatic in shape, with magnets embedded on its outer side. The connector 1 has a groove 102, the inner contour of which precisely matches the outer shape of the mounting base 2, and a magnet is also embedded within the groove 102. When the mounting base 2 is aligned with and pushed into the groove 102, the magnets on the outer side of the mounting base 2 and the magnets in the groove 102 attract each other due to their opposite polarities, causing the mounting base 2 to initially adhere to the groove 102. This method of using magnetic attraction facilitates the initial connection between the mounting base 2 and the connector 1 and ensures a certain degree of accuracy in the connection. Simultaneously, the back of the mounting base 2 has a socket 204, and the connector 1 has a rod 101. After the mounting base 2 and the connector 1 are initially attracted by the magnets, the rod 101 is inserted into the socket 204. Moreover, because the magnets in the mounting base 2 and the groove 102 also attract the rod 101, the connection stability between the mounting base 2 and the connector 1 is further enhanced. Through these two methods—magnetic attraction and the insertion of the rod 101 into the socket 204—the stability of the entire speaker assembly structure is ensured.

[0044] The mounting base 2 has a cable inlet 205 on its back. The cable of the speaker body 3 passes through the cable inlet 205 and connects to the external circuit. The design of the cable inlet 205 ensures a neat and orderly cable connection, avoiding tangled cables. At the same time, the cable inlet 205 protects the cable from damage caused by external factors. Its working principle is to ensure that current can be stably transmitted from the external circuit to the speaker body 3 through the properly connected cable, providing the necessary power for the normal operation of the speaker.

[0045] When the external circuit supplies power to the speaker body 3, if the speaker body 3 is a tweeter unit, according to the working principle of a tweeter, the change in current will drive the diaphragm inside the speaker to vibrate at high frequency. This high-frequency vibration rapidly compresses and releases air, thereby producing high-frequency sound. If the speaker body 3 is a woofer unit, similarly according to the working principle of a woofer, the current will drive the larger diaphragm to vibrate at low frequency. The low-frequency vibration causes the air to vibrate slowly, thus producing low-frequency sound. During the sound production process of the speaker body 3, the sound-insulating rubber pad on the side of the mounting base 2 near the sound-producing end of the speaker body 3 plays a role. Rubber has good sound insulation and vibration damping properties, which can effectively reduce the transmission of vibrations generated during speaker production to other components, reduce noise interference, ensure that the sound emitted by the speaker is clear and pure, and improve the sound propagation effect.
