Description

Technical Field

[0001] The utility model relates to the field of speakers, in particular to a wave-curve-uniform constant array speaker. Background Art

[0002] Current mainstream dual 6.5-inch, dual 8-inch, and dual 10-inch line array speakers are equipped with two mid-bass drivers and one or two compression driver tweeters, along with a fish-mouth horn and diffuser design. While these existing speaker designs offer powerful audio output and wide coverage, they also have potential acoustic and sound quality flaws. These primarily focus on high-frequency uniformity, low-frequency handling, phase coherence, and overall sound balance.

[0003] Therefore, in order to solve the above problems, it is necessary to modify the existing sound system design and focus on the matching and optimization of various components during speaker design and debugging to ensure the best performance of the sound system. Utility Model Content

[0004] In order to solve the above technical problems, a three-way linear array speaker with good sound quality and excellent effect is proposed.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A wave-curve uniform array speaker comprises a speaker body, a mounting plate provided in the center of the speaker body, two rows of mid-high frequency units mounted longitudinally on the tweeter mounting plate, and a row of tweeter units mounted between the two rows of mid-high frequency units; the mid-high frequency units and the tweeter units are coaxially arranged.

[0007] The backs of the mid-high frequency unit and the tweeter are of a trapezoidal structure. A woofer is installed on the backs of the tweeter and the tweeter, and the woofer is also installed coaxially with the tweeter and the tweeter.

[0008] Preferably, there are 10 mid-high frequency units in the two columns, 5 in each column, and the size of the mid-high frequency units is 3 inches.

[0009] Preferably, the column of tweeters has a total of 10 tweeters, and the size of each tweeter is 1 inch.

[0010] Preferably, the size of the one woofer is 12 inches.

[0011] Preferably, the connection board on the back of the speaker body is provided with a 37-core socket for receiving the signal of the audio power amplifier whose crossover point between the mid-bass unit and the tweeter is accurately set by DSP and whose phase is precisely adjusted.

[0012] Preferably, the speaker body has hanging parts on the left and right sides.

[0013] Preferably, each of the hanging parts is equipped with 2 pins.

[0014] Preferably, handles are provided on both sides of the speaker body.

[0015] Beneficial technical effects of this utility model:

[0016] The utility model sets low frequency, mid frequency and high frequency, which are processed independently by the mid-high frequency unit and the tweeter unit respectively. This frequency division design can achieve a smoother frequency response, avoid frequency overlap and interference problems, and thus provide a clearer and more delicate sound performance;

[0017] In addition, the mid-high frequency unit and the tweeter are arranged coaxially vertically and the woofer is installed on the back. This design can reduce the phase difference between the frequency bands, avoid sound quality problems caused by phase mismatch, and provide clearer, natural and uniform sound quality performance, greatly improving the quality and effect of the sound quality.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the present invention is not limited to the following specific embodiments.

[0025] like Figure 1-4As shown, a wave-curve uniform array speaker includes a speaker body 1, a mounting plate 15 is provided in the center of the speaker body, two rows of mid-high frequency units 2 are longitudinally mounted on the tweeter mounting plate 15, and a row of tweeter units 3 is mounted in the middle of the two rows of mid-high frequency units 2; the mid-high frequency units 2 and the tweeter units 3 are coaxially arranged and mounted; the back of the mid-high frequency units 3 and the tweeter units 3 are a trapezoidal structure, and a woofer 4 is mounted on the back of the mid-high frequency units 2 and the tweeter units 3, and the woofer 4 is also mounted coaxially with the tweeter units and the tweeter units.

[0026] The frequency range of the speaker sound frequency corresponding to the above woofer 4, mid-high frequency unit 2 and tweeter 3 is divided into low frequency, mid-frequency and high frequency ranges. Each frequency range is independently managed by a separate syllable unit. This frequency division design can achieve a smoother frequency response, avoid frequency overlap and interference problems, and thus provide a clearer and more delicate sound performance.

[0027] Specifically, the dimensions of each unit are as follows:

[0028] The two rows of mid-high frequency units 2 have a total of 10 units, with 5 units in each row. The mid-high frequency units 2 are 3-inch units in size. The row of tweeters 3 has a total of 10 tweeters, each of which is 1-inch in size. The size of the woofer 4 is 12 inches.

[0029] The mid- and high-frequency parts are handled by two rows of 3-inch drivers. These drivers can provide a more delicate sound field performance when processing the mid- and high-frequency bands. The design of the 1-inch tweeter row can better handle high-frequency details, making the high-frequency response more accurate and natural.

[0030] By placing the mid-high frequency unit 2 and tweeter 3 near coaxially, and rear-mounting the woofer 6, phase differences between frequency bands are reduced. This design improves phase consistency and avoids sound quality issues such as phase interference and frequency overlap caused by phase mismatch. Compared to traditional designs with two mid-high frequency units and a compression-driven tweeter, this design offers superior phase control, particularly in the mid- and high-frequency ranges, delivering a more natural and coherent sound quality.

[0031] In addition, the use of multiple small-sized units (3-inch and 1-inch units) arranged vertically enables the speaker to more precisely control the directionality of the sound waves. The combination of multiple small units can achieve more delicate beam control, thereby optimizing the sound field coverage and reducing blind spots and hot spots in the sound field.

[0032] In comparison, the traditional design of dual mid-bass units and compression-driven tweeters may have a stronger sound pressure level, but it lacks the accuracy of beam control and is prone to high-frequency directional distortion.

[0033] The design of multiple small units arranged vertically helps to achieve more uniform vertical sound field coverage, so that listeners at different heights can get a consistent listening experience. This is especially important for large spaces or places with multiple audience levels (such as theaters and performance venues).

[0034] The 12-inch woofer is mounted behind the midrange, tweeter, and midrange drivers, and is arranged coaxially. This design not only saves space but also improves low-frequency phase coherence, providing a tighter and clearer low-frequency response. Because the 12-inch woofer is positioned closer to the midrange, tweeter, and midrange drivers, sound waves from the low and other frequency bands are radiated more evenly to the listening area. This reduces the concentration and accumulation of low-frequency energy, avoiding the muddiness caused by overexcitation of the low frequencies.

[0035] Preferably, the connection board 6 on the back of the speaker body is provided with a 37-pin socket 16 for receiving the signal of the audio power amplifier with precise phase adjustment and precise frequency division point between the mid-bass unit and the tweeter set by DSP.

[0036] The speaker body 1 has hanging parts 7 on both sides. Each hanging part is equipped with two latches 8. The hanging parts on the front of the speaker body are fixed-angle, while the rear part is equipped with adjustable angle latch holes 11 for flexible adjustment of the tilt angle. The hanging parts 7 have connecting pieces 12 inside.

[0037] The speaker body 1 has 8-corner brackets 13 at the joints of the panels to enhance the stability and safety of the enclosure. Handles 9 are located on both sides of the speaker body for easy transport, and a mesh cover 10 is installed on the front of the enclosure for protection. The location and function of the sealing cover 14 mentioned in the accompanying drawings are also provided.

[0038] Overall, this embodiment outperforms traditional dual 8- or dual 10-inch line array speakers in terms of frequency response, beam control, low-frequency performance, design flexibility, and aesthetics. By utilizing a coaxial design for mid-high and tweeter frequencies, precise beam control, a compact low-frequency design, and intelligent frequency distribution, the speaker design delivers clearer, more natural, and more uniform sound quality, making it particularly suitable for demanding audio applications.

[0039] Based on the disclosure and teachings of the above specification, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this specification, these terms are for convenience only and do not constitute any limitation to the present invention.
