Description

Technical Field

[0001] This utility model relates to the field of audio design, and in particular to a midrange compression and diffusion structure for audio equipment. Background Technology

[0002] Audio systems specifically refer to a combination of electrical equipment that produces sound. The history of audio technology development can be divided into four stages: vacuum tubes, transistors, integrated circuits, and field-effect transistors. However, ordinary audio systems used as stage audio systems experience a significant decrease in sound intensity in audience seats far from the stage, resulting in a poor sound effect from the audience's perspective, especially for rhythmic music, where they often fail to achieve a truly impactful experience.

[0003] To address this, a horn-loaded subwoofer is disclosed in the prior art (Announcement No.: CN 206283654 U, Announcement Date: 2017.06.27). It is equipped with a high-frequency remote horn, which reduces the high-frequency diffusion surface and enables it to transmit further. Due to the presence of a bass phaser, the bass is compressed through the sound hole of the compression plate before being transmitted, which generates sound pressure and increases the sound intensity at a distance. The compression of the sound hole of the compression plate and the cooperation of the bass horn plate make the sound range longer and more powerful.

[0004] However, in the above scheme, the structure of the high-frequency remote horn is fixed, so the speaker structure can only produce one sound effect, making it difficult to be applicable to different application scenarios. Therefore, it is necessary to design a mid-frequency compression and diffusion structure with adjustable sound effects to solve this technical problem. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A midrange compression and diffusion structure for an audio system includes an audio enclosure, wherein a tweeter horn is fixedly installed in the center of the audio enclosure, and a woofer horn is fixedly installed on both sides of the audio enclosure.

[0007] Two mid-range compression mechanisms are rotatably installed in the middle of the front side of the speaker enclosure. The mid-range compression mechanisms are arranged one-to-one between the tweeter horn and the woofer horn, and the mid-range compression mechanisms control the output angle of the tweeter horn when flipped open and closed.

[0008] A drive mechanism is fixedly installed inside the speaker enclosure, which drives two mid-range compression mechanisms to rotate synchronously.

[0009] Furthermore: the front surfaces of the two midrange compression mechanisms form a diffusion structure that is wider at the front and narrower at the back, and a sound outlet gap is left between the two midrange compression mechanisms, with the treble horn positioned behind the sound outlet gap.

[0010] Furthermore: the mid-range compression mechanism includes a positioning bracket and a flip cover plate. The front side of the positioning bracket is formed with a sound amplification groove. A first hinge position is provided on the side of the positioning bracket near the sound outlet gap. A second hinge position is provided on the side of the flip cover plate near the sound outlet gap. The second hinge position is rotatably fitted on the first hinge position, and the flip cover plate covers the front of the sound amplification groove.

[0011] Furthermore, the two flip-up covers of the midrange compression mechanism form a diffusion structure that is wider at the front and narrower at the back.

[0012] Furthermore: a rotating shaft is fixedly installed in the second hinge position, and the rotating shaft is rotatably fitted in the first hinge position. A gear is fixedly installed on the rotating shaft, and the rotating shafts of the two flip-up covers are driven by meshing gears.

[0013] Furthermore: a first pulley is fixedly mounted on one of the rotating shafts, the drive mechanism is a servo motor, a second pulley is fixedly mounted on the rotor of the servo motor, and a transmission belt is fitted between the first pulley and the second pulley.

[0014] Furthermore: a first clearance groove is formed in the middle of one of the positioning brackets, a first pulley is fitted into the first clearance groove with clearance, and a transmission belt passes through the first clearance groove and is fitted between the first pulley and the second pulley.

[0015] Furthermore: the flip cover plate has two second clearance grooves formed on the side near the sound outlet gap, and two gears are provided on the rotating shaft, with the two gears corresponding to each other and fitted into the second clearance grooves.

[0016] Furthermore: vertical rods are fixedly installed on both the left and right sides of the front side of the speaker enclosure. The upper end of the vertical rod is formed with a hanging edge, and the lower end of the vertical rod is formed with an assembly hole. There are two or more speaker enclosures, and the hanging edges between two adjacent speaker enclosures are fitted into the assembly holes with a one-to-one gap.

[0017] Furthermore: the suspension edge is formed with a suspension hole, and a locking bolt is provided on the outer side of the lower end of the vertical rod. When the suspension edge is inserted into the assembly hole with a one-to-one clearance fit, the locking bolt passes through the suspension hole to lock the bolt.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the drive mechanism is used to control the opening or closing of the mid-range compression mechanism on both sides. Since the mid-range compression mechanism on both sides can rotate synchronously, the sound output angle of the tweeter can be effectively controlled when opening and closing, thereby forming a diffusion structure at different angles to diffuse the volume. Combined with the woofer, the mid-range of the speaker can be controlled, which can be applied to different scenarios.

[0034] like Figure 1-7 As shown, a mid-range compression and diffusion structure 6 for audio equipment according to this utility model includes an audio enclosure 1, a tweeter horn 2 fixedly installed in the middle of the audio enclosure 1, and a woofer horn 3 fixedly installed on both sides of the audio enclosure 1.

[0035] Two mid-range compression mechanisms 4 are rotatably installed in the middle of the front side of the speaker enclosure 1. The mid-range compression mechanisms 4 are arranged one-to-one between the tweeter horn 2 and the woofer horn 3, and the mid-range compression mechanisms 4 control the output angle of the tweeter horn 2 when flipped open and closed.

[0036] A drive mechanism 5 is fixedly installed inside the speaker enclosure 1. The drive mechanism 5 drives two mid-range compression mechanisms 4 to perform synchronous flipping motion.

[0037] The principle is as follows: the drive mechanism 5 is used to control the opening or closing of the mid-range compression mechanism 4 on both sides. Since the mid-range compression mechanism 4 on both sides can rotate synchronously, the output angle of the tweeter horn 2 can be effectively controlled when it is opened and closed, thereby forming a diffusion structure 6 at different angles to diffuse the volume. Combined with the bass horn 3, the mid-range of the speaker can be controlled, which can be applied to different scenarios.

[0038] Furthermore: the front surfaces of the two midrange compression mechanisms 4 form a diffusion structure 6 that is wider at the front and narrower at the back, and a sound outlet gap 7 is left between the two midrange compression mechanisms 4. The tweeter horn 2 is located behind the sound outlet gap 7. When adjusting the flip angle of the midrange compression mechanism 4, the sound outlet width of the diffusion structure 6 can be controlled accordingly. By changing the angle of the diffusion structure 6, the sound of the speaker can be adjusted, making the speaker suitable for different scenarios.

[0039] Furthermore: the midrange compression mechanism 4 includes a positioning bracket 41 and a flip cover 42. The positioning bracket 41 is fixedly installed on the front side of the speaker enclosure 1. The front side of the positioning bracket 41 is formed with a sound amplification groove 8. A first hinge position 9 is provided on the side of the positioning bracket 41 near the sound outlet gap 7. A second hinge position 10 is provided on the side of the flip cover 42 near the sound outlet gap 7. The second hinge position 10 is rotatably fitted on the first hinge position 9, and the flip cover 42 covers the front of the sound amplification groove 8. The flip covers 42 of the two midrange compression mechanisms 4 can be synchronously flipped and adjusted to control the angle of the diffusion structure 6, thereby regulating the sound output effect of the speaker. The setting of the first hinge position 9 and the second hinge position 10 can ensure the stable flipping movement of the flip cover 42.

[0040] Furthermore, the two mid-range compression mechanisms 4 form a diffusion structure 6 that is wider at the front and narrower at the back; the sound output effect of the speaker can be controlled by adjusting the angle of the diffusion structure 6, thereby making the speaker suitable for different application scenarios.

[0041] Furthermore: A rotating shaft 11 is fixedly installed inside the second hinge position 10. The rotating shaft 11 is rotatably fitted in the first hinge position 9. A gear 12 is fixedly installed on the rotating shaft 11. The rotating shafts 11 of the two flip covers 42 are meshed and driven by the gear 12, so that the flip covers 42 on both sides can be opened or closed synchronously, which is convenient for actual adjustment.

[0042] Furthermore: a first pulley 13 is fixedly installed on one of the rotating shafts 11, the drive mechanism 5 adopts a servo motor, a second pulley 14 is fixedly installed on the rotor of the servo motor, and a transmission belt 22 is installed between the first pulley 13 and the second pulley 14; the two rotating shafts 11 can be controlled to operate by belt transmission, and the gear 12 can be set so that the two rotating shafts 11 rotate in opposite directions, thereby ensuring that the two flip-top covers 42 are controlled to flip open or close synchronously.

[0043] Furthermore, one of the positioning brackets 41 has a first clearance groove 15 formed in the middle, the first pulley 13 is fitted into the first clearance groove 15 with clearance, and the transmission belt passes through the first clearance groove 15 and is fitted between the first pulley 13 and the second pulley 14; this can achieve the effect of avoiding the transmission belt 22 and the first pulley 13, thereby ensuring the stable installation of the belt mechanism.

[0044] Furthermore: the flip cover plate 42 has two second clearance grooves 16 formed on the side near the sound outlet gap 7, and two gears 12 are provided on the rotating shaft 11, and the two gears 12 are installed in the second clearance grooves 16 with a one-to-one corresponding clearance fit; the installation of the gears 12 can be completed by the space clearance, ensuring that the rotation directions between the two rotating shafts 11 are opposite.

[0045] Furthermore, vertical rods 17 are fixedly installed on both the left and right sides of the front of the speaker enclosure 1. The upper end of the vertical rod 17 is formed with a hanging edge 18, and the lower end of the vertical rod 17 is formed with an assembly hole 19. There are two or more speaker enclosures 1, and the hanging edges 18 between two adjacent speaker enclosures 1 are aligned with the gaps and inserted into the assembly holes 19. This allows for the assembly of multiple speaker enclosures 1, and the appropriate number of speaker enclosures 1 can be selected for use according to different application scenarios to ensure the sound effect of the speaker.

[0046] Furthermore: The suspension edge 18 is formed with a suspension hole 20, and a locking bolt 21 is provided on the outer side of the lower end of the vertical rod 17. When the suspension edge 18 is inserted into the assembly hole 19 with a corresponding gap fit, the locking bolt 21 passes through the suspension hole 20 to lock the bolt. After the multiple speaker cabinets 1 are installed, the locking bolt 21 can be used to lock them, thereby achieving stable assembly between the multiple speaker cabinets 1.

[0047] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
