Description

Technical Field

[0001] This utility model relates to the field of audio technology, specifically to an audio system with an adjustable sound transmission range. Background Technology

[0002] Audio systems specifically refer to a set of audio systems that combine electrical equipment to produce sound. A very important component of an audio system is the speaker enclosure, which is generally composed of a speaker unit and a cabinet. In actual use, existing audio systems often only allow adjustment of the volume to control the sound level, while the sound transmission range is often inconvenient. They cannot be adjusted according to the size of the venue to change the sound transmission range, which is not conducive to users' better experience of the sound effects.

[0003] An existing patent (publication number: CN222691839U) discloses a speaker with adjustable sound transmission range, including a support column, a support assembly installed at the lower end of the support column, a movable rod movably installed inside the support column, a mounting plate fixedly installed at the top of the movable rod, a speaker fixedly installed at the upper end of the mounting plate, a sound outlet hole opened on the front of the speaker plate, and adjustment mechanisms symmetrically installed on both sides of the sound outlet hole, a through hole opened on the top front of the support column, an adjustment bolt movably inserted into the through hole, and multiple sets of screw holes evenly distributed on the surface of the movable rod.

[0004] During use, the aforementioned patent, through the adjustment mechanism, with the cooperation of the guide groove, guide block, side plate, sound sealing plate, and handle, allows the sound sealing plate to be pulled inward by the handles on both sides, so that the sound sealing plate blocks the sound outlet on the speaker, thereby making the sound transmission more concentrated and the sound range wider. However, in use, it can only change the size of the sound outlet by blocking it, but the distance from the speaker body to the sound outlet does not change, and the directivity of the speaker does not change either, resulting in a poor actual adjustment effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a speaker with an adjustable sound transmission range, which has the advantages of flexible adjustment and good adjustment effect, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a speaker with adjustable sound transmission range, comprising a support assembly and an outer shell mounted on the support assembly, wherein a loudspeaker is disposed inside the outer shell, the loudspeaker is connected to an external control device via a cable, and an adjustment assembly is disposed between the outer shell and the loudspeaker;

[0007] The adjustment assembly includes a fixing plate fixed to the inner wall of the outer shell, a support plate mounted on the back of the speaker, a tapered corrugated tube installed between the fixing plate and the support plate, a track groove fixed to the inner wall of the outer shell, a cross-shaped movable plate fixed to the right side of the support plate, and the end of the cross-shaped movable plate being slidably connected to the track groove.

[0008] Furthermore, the opening at the left end of the conical bellows is larger than that at the right end.

[0009] The above method alters the shape of the conical corrugated tube by moving the support plate left and right, thereby changing the directivity of the loudspeaker.

[0010] Furthermore, an electric actuator is installed on the inner wall of the outer casing, and the output end of the electric actuator is fixed to the cross-shaped moving plate.

[0011] The above scheme allows the electric actuator to move the cross-shaped moving plate, which in turn moves the supporting plate.

[0012] Furthermore, a protective cover is installed on the left end of the outer casing.

[0013] The above solution ensures that the protective cover can protect the speaker while ensuring that the sound is transmitted normally.

[0014] Furthermore, the interior of the outer shell is filled with rubber particles.

[0015] The above solution enhances sound insulation by filling the interior of the outer shell with rubber particles. The rubber particles can absorb high-frequency resonance noise and ensure that sound energy propagates directionally through the conical corrugated pipe.

[0016] Furthermore, the support assembly includes a support plate, the outer shell is mounted on the upper surface of the support plate, a plug rod is inserted into the bottom surface of the support plate, and the support assembly includes a tripod, with the plug rod inserted into the tripod.

[0017] The above method allows for adjustment of the height of the support plate by adjusting the length of the extension rod beyond the tripod.

[0018] Furthermore, the side of the insertion rod is provided with multiple slots, and the side of the tripod is provided with a limiting groove, at which a limiting rod is inserted.

[0019] The above method allows for the adjustment of the insertion rod's height and the maintenance of its stability by having the limiting rod pass through the limiting groove and be inserted into the slot.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] This type of speaker with adjustable sound transmission range uses an adjustment component. An electric actuator moves a cross-shaped moving plate, which in turn moves a support plate. The movement of the support plate moves the speaker and changes the shape of the conical bellows. This change in the shape of the conical bellows alters the directivity of the speaker. Combined with the adjustment of the speaker's position relative to the protective cover, the speaker's sound transmission range can be quickly adjusted. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3The speaker with adjustable sound transmission range in this embodiment includes a support component 1 and an outer shell 2 installed on the support component 1. A speaker 3 is provided inside the outer shell 2. The speaker 3 is connected to an external control device via a cable. An adjustment component 4 is provided between the outer shell 2 and the speaker 3.

[0034] Please see Figure 2 , Figure 3 and Figure 5 The adjustment component 4 includes a fixing plate 401 fixed to the inner wall of the outer shell 2, a support plate 402 mounted on the back of the speaker 3, a conical corrugated tube 403 installed between the fixing plate 401 and the support plate 402, the conical corrugated tube 403 being made of silicone, a track groove 404 fixed to the inner wall of the outer shell 2, a cross moving plate 405 fixed to the right side of the support plate 402, and the end of the cross moving plate 405 being slidably connected to the track groove 404.

[0035] Please see Figure 2 , Figure 3 and Figure 5 The left end of the conical corrugated tube 403 has a larger opening than the right end. The shape of the conical corrugated tube 403 changes as the bearing plate 402 moves left and right, thereby changing the directivity of the speaker 3. An electric push rod 406 is installed on the inner wall of the outer casing 2. The output end of the electric push rod 406 is fixed to the cross moving plate 405. The electric push rod 406 can drive the cross moving plate 405 to move, thereby driving the bearing plate 402 to move.

[0036] Please see Figure 2 , Figure 3 and Figure 4 The left end of the outer shell 2 is equipped with a protective cover 5. The protective cover 5 can protect the speaker 3 while ensuring that the sound can be transmitted normally. The interior of the outer shell 2 is filled with rubber particles 6. The rubber particles 6 inside the outer shell 2 can enhance the sound insulation effect. The rubber particles 6 can absorb high-frequency resonance noise and ensure that the sound energy is transmitted directionally through the conical corrugated tube 403.

[0037] Please see Figure 2 , Figure 3 and Figure 5The support assembly 1 includes a support plate 101, and a housing 2 is installed on the upper surface of the support plate 101. A rod 102 is inserted into the bottom surface of the support plate 101. The support assembly 1 includes a tripod 103. The rod 102 is inserted into the tripod 103. The height of the support plate 101 can be adjusted by adjusting the length of the rod 102 extending out of the tripod 103. Multiple slots 104 are provided on the side of the rod 102. A limiting groove 105 is provided on the side of the tripod 103. A limiting rod 106 is inserted into the limiting groove 105. The limiting rod 106 passes through the limiting groove 105 and is inserted into the slot 104 to complete the height adjustment of the rod 102 and maintain the stability of the rod 102.

[0038] It should be noted that before use, the position of the tripod 103 should be adjusted in advance and the insertion rod 102 should be inserted, and the limit rod 106 should be installed to ensure the stability of the insertion rod 102 after insertion.

[0039] The working principle of the above embodiment is as follows: After the support component 1 is installed, the outer shell 2 is installed on the upper surface of the support plate 101. When it is necessary to adjust the sound transmission range, the electric push rod 406 is controlled by the external control device to drive the cross moving plate 405 to move. The movement of the cross moving plate 405 drives the bearing plate 402 to move. The movement of the bearing plate 402 drives the speaker 3 to move and changes the shape of the conical corrugated tube 403. When the distance between the speaker 3 and the fixed plate 401 is far, the conical corrugated tube 403 takes the shape of a horn, and the sound energy is concentrated in a narrow angle range for radiation. This greatly reduces the waste of sound energy to non-target areas, making the sound pressure level higher and the attenuation slower in the main axis direction. Therefore, the sound can spread farther and clearer in the main axis direction, which is suitable for large venues, outdoor performances, and long-distance sound reinforcement.

[0040] When the distance between the speaker 3 and the fixed plate 401 is relatively close, the conical bellows 403 is compressed, and the sound emitted from the speaker 3 diffuses directly, dispersing the sound energy over a wider area. Although the coverage area is large, the initial sound pressure level in the main axis direction is relatively low, and the sound energy diffuses in all directions, resulting in faster attenuation and a shorter effective transmission distance. This makes it suitable for near-field listening and small spaces requiring wide coverage. In addition, by adjusting the position of the speaker 3 to the protective cover 5, the sound transmission range can be quickly adjusted.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
