Description

Technical Field

[0001] The utility model relates to the technical field of speaker equipment, in particular to a sound waveguide horn structural component in a speaker. Background Art

[0002] Waveguide horns are a key technology in audio engineering, widely used in high-performance speaker systems, particularly in professional audio and high-end home audio equipment. Their basic principles are derived from acoustic theory in physics, using the geometry of the horn to control the propagation of sound waves, thereby optimizing the diffusion characteristics of sound. To further improve sound quality, modern waveguide horns are often equipped with a phase plug, a small device located in the horn throat that is specifically designed to control the phase of sound waves, reduce internal reflections, and ensure the consistency and flatness of the sound wavefront. Waveguide horns not only improve the performance of speaker systems, but also provide listeners with a more realistic and detailed listening experience. For speakers with multiple midrange drivers, inconsistent sound guidance phases and reflections of sound waves from within the speaker back to the speaker can cause audio distortion and compromised sound quality. Utility Model Content

[0003] To solve the problem that speakers with multiple mid-range speakers have inconsistent sound guidance phases, and sound waves inside the speakers are reflected back to the speakers, causing audio distortion and damaged sound quality.

[0004] The utility model provides a midrange waveguide horn structural component of a speaker, comprising a main body and a phase plug group; a first mounting portion and a second mounting portion of a hollow structure are symmetrically provided on both sides of the main body; the phase plug group comprises a plurality of phase plug units arranged at equal intervals on the first mounting portion and the second mounting portion, and the phase plug units are used for mounting the midrange speaker.

[0005] Preferably, the phase plug unit is provided with a sound inlet, a sound cavity and a sound outlet which are interconnected, and the midrange speaker is installed at the sound inlet.

[0006] Preferably, the area of the sound outlet is smaller than the area of the sound inlet.

[0007] Preferably, the first mounting portion and the second mounting portion are both provided with n phase plug units, the sound inlets have the same shape and size, the sound outlets are arranged to form a circular structure, and the sound cavities are independent of each other.

[0008] Preferably, n is 1, 2, 4, 6, 8, or 10.

[0009] Preferably, the main body portion includes a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are fixedly connected to both sides of the first mounting portion and the second mounting portion respectively, and the first connecting plate and the second connecting plate are both provided with fixing holes.

[0010] Preferably, a reinforcement is provided between the first connecting plate and the second connecting plate, and one side of the reinforcement is fixedly connected to the outer side of the first mounting portion, or one side of the reinforcement is fixedly connected to the outer side of the second mounting portion.

[0012] Preferably, the angle θ is 50°.

[0013] Preferably, the body portion and the phase plug set are both made of metal material.

[0014] The beneficial effects of this utility model are reflected in the fact that by providing multiple phase plug units, each corresponding to a midrange speaker, the sound waves radiated in all directions by the midrange speaker are collected and compressed, thereby improving the sound compression ratio, correcting the sound propagation path, and enhancing sensitivity. Furthermore, it effectively expands the speaker's frequency response range and optimizes the frequency response phase characteristics, enabling more accurate sound and image positioning. This solves the problem of inconsistent sound guidance phases in speakers equipped with multiple midrange speakers, and the reflection of sound waves from the speaker back to the speaker, which causes audio distortion and poor sound quality.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Reference Figure 1-Figure 3A midrange waveguide horn structural component of a speaker includes a main body 1 and a phase plug group; a first mounting portion 11 and a second mounting portion 12 of a hollow structure are symmetrically provided on both sides of the main body 1; the phase plug group includes a plurality of phase plug units 2 arranged at equal intervals on the first mounting portion 11 and the second mounting portion 12, and the phase plug unit 2 is used to install the midrange speaker.

[0021] By installing multiple phase plug units 2, each with a corresponding midrange speaker, the sound waves radiated in all directions by the midrange speaker are collected and compressed, thereby improving the sound compression ratio, correcting the sound propagation path, and enhancing sensitivity. This effectively expands the speaker's frequency response range and optimizes the frequency response phase characteristics, enabling more accurate sound and image positioning. This solves the problem of inconsistent sound guidance phases in speakers equipped with multiple midrange speakers, and the reflection of sound waves from the speaker back to the speaker, which causes audio distortion and poor sound quality.

[0022] In some embodiments, as Figure 3 As shown, the phase plug unit 2 is provided with a sound inlet 21 , a sound cavity 22 and a sound outlet 23 which are interconnected, and the midrange speaker is installed at the sound inlet 21 .

[0023] The sound is transmitted from the midrange speaker through the sound inlet 21, the sound cavity 22 and the sound outlet 23 in sequence, and the propagation path of the sound is controlled by the setting of the phase plug unit 2.

[0024] Furthermore, the area of the sound outlet 23 is smaller than the area of the sound inlet 21, so as to collect and compress the sound waves radiated in all directions by each mid-range speaker.

[0025] Furthermore, the first mounting portion 11 and the second mounting portion 12 are both provided with n phase plug units 2 , the sound inlets 21 have the same shape and size, the sound outlets 23 are arranged to form a circular structure, and the sound cavities 22 are independent.

[0026] The sound inlets 21 are of the same shape and size to accommodate midrange speakers of the same model. The sound outlets 23 are arranged in a circular structure. This not only concentrates the sound waves, but also visually appeals more than straight lines or other shapes, making them a practical and aesthetically pleasing decorative element, thereby boosting sales. The independent sound chambers 22 control the diffusion angle of the sound waves, improving the speaker's directivity and allowing the sound to travel farther or be more concentrated in a specific direction. Furthermore, the independent sound chambers 22 provide acoustic isolation for the different sound-emitting units, preventing interference between sounds of different frequency bands.

[0027] Preferably, n is 1, 2, 4, 6, 8, or 10.

[0028] More specifically, when n is 4 and both the first mounting portion 11 and the second mounting portion 12 are provided with four phase plug units 2 , the effects of compressing sound waves and optimizing frequency response phase characteristics are best.

[0029] In some embodiments, as Figure 1 As shown, the main body 1 includes a first connecting plate 13 and a second connecting plate 14, which are fixedly connected to the first mounting portion 11 and the second mounting portion 12, respectively. Fixing holes 15 are provided on each of the first and second connecting plates 13, 14. The design of the first and second connecting plates 13, 14, and the fixing holes 15 facilitates the connection of the acoustic waveguide horn structure to the speaker.

[0030] Further, such as Figure 1 As shown, a reinforcement 16 is provided between the first connecting plate 13 and the second connecting plate 14 , and one side of the reinforcement 16 is fixedly connected to the outer side of the first mounting portion 11 , or one side of the reinforcement 16 is fixedly connected to the outer side of the second mounting portion 12 .

[0031] The provision of the reinforcement 16 makes the structure of the sound waveguide horn structural component in the speaker more stable and reduces resonance caused by vibration, which helps to maintain the clarity and accuracy of the sound and prevent unnecessary sound distortion.

[0032] In some embodiments, the hollow structure of the first mounting portion 11 is in the shape of a truncated cone, such as Figure 3 As shown, the angle θ of the cross section of the first mounting portion 11 is 30° to 80°.

[0033] Larger angles, such as 70° and 80°, collect less sound waves and allow the sound to spread wider, making them suitable for situations that require wide coverage, such as home theaters or large venues. Smaller angles, such as 30°, can make the sound more concentrated and spread farther, while reducing lateral diffusion, making them suitable for applications that require concentrated sound propagation, such as stage monitoring.

[0034] More specifically, the angle θ is 50°, and the acoustic waveguide horn structural component of the speaker is suitable for most scenarios.

[0035] In some embodiments, the body portion 1 and the phase plug set are both made of metal material.

[0036] Metal materials have higher rigidity, which can reduce mechanical vibration and thus reduce sound distortion.
