Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a multi-channel loudspeaker. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. The loudspeaker is the weakest component in an audio system, yet it is also one of the most crucial for achieving optimal sound effects. There are many types of loudspeakers, and their prices vary considerably. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate and resonate with the surrounding air, producing sound.

[0003] A search revealed a Chinese patent publication number (CN 217546233 U) that discloses a speaker with an easily installable speaker diaphragm. The speaker includes a speaker body, with a speaker diaphragm body located at one end of the speaker body. Mounting grooves are formed on the bottom and upper sides of the inner wall of the speaker body near the speaker diaphragm body. A fixing block is fixedly connected inside the mounting groove. A first mounting strip is fixedly connected to the end of the mounting groove near the speaker diaphragm body, passing through the speaker body. Second mounting strips are fixedly connected to both ends of the outer side of the speaker diaphragm body. A filter screen is located on the side of the second mounting strip away from the first mounting strip. A first fixing rod and a second fixing rod are located on the side of the fixing block near the speaker diaphragm body. This invention facilitates the installation of the speaker diaphragm and filter screen on the speaker, and allows for easy disassembly and repair of the speaker diaphragm and filter screen.

[0004] The speakers in the aforementioned patents still have certain shortcomings. When used outdoors, existing multi-channel speakers are often supported and fixed by bulky mounting bases, which lack corresponding directional adjustment functions. Consequently, when sound needs to be played from different directions, staff need to move and rotate the mounting base, which is labor-intensive and extremely inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-channel loudspeaker that solves the problem that existing multi-channel loudspeakers, when used outdoors, are often supported and fixed by bulky mounting bases, lack corresponding directional adjustment functions, and therefore require workers to move and rotate the mounting base when sound needs to be played from different directions, resulting in high labor intensity and extreme inconvenience in use.

[0025] Please see Figure 1-4 ,

[0026] Example 1: A multi-channel loudspeaker includes a support base 1. The bottom of the support base 1 is evenly provided with bottom mounting grooves 2 around its bottom end. Each bottom mounting groove 2 is provided with a movable wheel 3. The top of the support base 1 is provided with an orientation adjustment component 4. The orientation adjustment component 4 is provided with a loudspeaker body 5. The outside of the loudspeaker body 5 is provided with an outer protective component 6. The side of the support base 1 is provided with a push handle 7.

[0027] The orientation adjustment component 4 includes a central mounting groove 401 located in the middle of the support base 1. A drive motor 402 is installed in the central mounting groove 401. A support connecting plate 403 is installed above the central mounting groove 401. A limiting mounting groove 404 is opened at the top of the support connecting plate 403. Two clamping connecting plates 405 are symmetrically arranged on both sides of the limiting mounting groove 404. Two drive screw holes 406 are symmetrically opened on the inner walls of both sides of the limiting mounting groove 404. A contact screw 407 is inserted into each drive screw hole 406. The end of the contact screw 407 is rotatably connected to the side of the clamping connecting plate 405. A rotating connecting column 408 is provided in the middle of the bottom end of the support connecting plate 403. The bottom end of the rotating connecting column 408 is fixedly connected to the output shaft of the drive motor 402. A rotating limiting ring 409 is provided on the outer side of the support connecting plate 403.

[0028] The outer protective component 6 includes an outer protective cover 601 fitted on the outside of the speaker body 5. The bottom of the outer protective cover 601 is evenly provided with connecting slots 602 around its perimeter. The top of the support base 1 is evenly provided with connecting posts 603 around its perimeter. The connecting posts 603 are inserted into the connecting slots 602.

[0029] Example 2: The difference between this example and Example 1 is that the width of the limiting mounting groove 404 is greater than the bottom width of the speaker body 5.

[0030] This makes it easier for the bottom of the speaker body 5 to be placed in the limiting mounting groove 404 for limiting and fixing.

[0031] Example 3: The difference between this example and Example 1 is that the side of the clamping connecting plate 405 is provided with an anti-slip pad.

[0032] This makes the bottom of the speaker body 5 more firmly clamped when the abutting screw 407 pushes the clamping connecting plate 405.

[0033] Example 4: The difference between this example and Example 1 is that the outer protective cover 601 is a compartment with one end open.

[0034] This makes it easier to install the outer protective cover 601 on the outside of the speaker body 5.

[0035] In this embodiment, since existing multi-channel loudspeakers are often supported and fixed by bulky mounting bases when used outdoors, they lack corresponding orientation adjustment functions. As a result, when sound needs to be played from different directions, the staff needs to move and rotate the mounting base, which is labor-intensive and extremely inconvenient to use.

[0036] In summary, in specific implementation, by providing an orientation adjustment component 4 on the support base 1, wherein the limiting mounting groove 404 in the orientation adjustment component 4 can provide support and limitation for the bottom of the speaker body 5, when the bottom of the speaker body 5 is placed in the limiting mounting groove 404, and the speaker body 5 is model Focal Aria K2, the user can rotate the abutment screw 407 so that the abutment screw 407 pushes the clamping connecting plate 405 to abut and clamp the two sides of the bottom of the speaker body 5, ensuring that the speaker body 5 is stably fixed on the support base 1.

[0037] When the user needs to adjust the playback position of the speaker body 5, the drive motor 402 connected to the ground can be started. The drive motor 402 rotates the support connecting plate 403 by rotating the connecting column 408, thereby causing the speaker body 5 fixed on the support connecting plate 403 to rotate. This allows the position of the speaker body 5 to be adjusted quickly and conveniently, making it easier for the user to turn around and operate more flexibly.

[0038] The support base 1 has casters 3 evenly arranged around its bottom, making the overall movement of the device more convenient. The outer protective component 6 is fitted onto the outside of the speaker body 5. The outer protective cover 601 of the outer protective component 6 has connecting slots 602 evenly arranged around its bottom. The connecting slots 602 can be inserted and limited by the connecting posts 603, so that the outer protective cover 601 can be stably fitted onto the outside of the speaker body 5, providing effective protection for the speaker body 5 during daily storage and ensuring the safe use of the speaker body 5.
