The sound-absorbing member is disposed on a side adjacent to the adjacent sound unit and partially covers the speaker opening in the direction of sound wave output. By varying the arrangement of the sound units and providing a sound-absorbing member within each sound unit, the sound units are arranged sequentially along a circular arc segment with a preset angle. This expands the sound coverage range while reducing mutual interference between adjacent sound units, thereby enhancing the audience's auditory experience.

[0034] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings.

[0035] Reference Figure 2 According to the first embodiment of the present invention, a wide-range sound box 1000 includes at least three audio units 100 arranged sequentially along a circular arc segment with a preset angle. Each audio unit 100 includes a speaker 140 and a sound absorber 150. The sound absorber 150 is positioned on the side adjacent to the adjacent audio unit 100 and partially covers the opening of the speaker 140 in the direction of sound wave output. By varying the arrangement of the audio units, the sound coverage can be expanded. Furthermore, the sound absorber within each audio unit reduces mutual interference between adjacent sound waves, thereby enhancing the audience's auditory experience.

[0036] It is understood that a wide-range speaker 1000 includes three or more audio units 100, with the different audio units 100 arranged sequentially along arc segments with predetermined angles, resulting in a fan-shaped sound propagation range. In other words, as the number of audio units 100 increases, the fan-shaped angle increases, and the sound coverage of the speaker also increases.

[0037] It is understandable that adjacent audio units 100 are provided with sound absorbing members 150 on adjacent sides, and the sound absorbing members 150 cover part of the opening in the sound wave output direction of the speaker 140, which can effectively prevent the sound waves between adjacent audio units 100 from interfering with each other.

[0038] Specifically, in some embodiments, when multiple audio units 100 are arranged sequentially along an arc segment having a preset angle, only when an audio unit 100 is adjacent to an audio unit 100 on both sides is the audio unit 100 provided with two attracting members, and the sound absorbing member 150 is provided in the direction of sound wave output, covering both sides of the opening of the speaker 140. When an audio unit 100 is adjacent to an audio unit 100 on only one side, the audio unit 100 is provided with only one sound absorbing member 150, and the sound absorbing member 150 is provided on the side closest to the adjacent audio unit 100, covering part of the opening of the speaker 140 in the direction of sound wave output.

[0039] According to some embodiments of the present invention, referring to Figure 1 The wide-range speaker 1000 also includes a connecting assembly 180, which detachably connects two adjacent speaker units 100. These detachable connections can be made using bolts, snaps, or other methods. This detachable connection allows for flexible use by adjusting the number of speaker units 100 and adapting the speaker's sound coverage requirements to different scenarios.

[0040] According to some embodiments of the present invention, referring to Figure 1 The connecting assembly 180 includes a first clamping member 181 and a second clamping member 182. The first clamping member 181 is provided on one of the two adjacent speaker units 100; the second clamping member 182 is provided on the other of the two adjacent speaker units 100. The second clamping member 182 is detachably connected to the first clamping member 181. The detachable connection allows the speaker unit 100 to be removed and installed.

[0041] Specifically, in some embodiments, the first engaging member 181 is configured as a buckle, and the second engaging member 182 is configured as a slot that matches the buckle of the first engaging member 181, and the buckle and slot are connected by a locking mechanism. The buckles and slots between adjacent audio units 100 are connected by a locking mechanism and are arranged in sequence along an arc segment with a predetermined angle.

[0042] According to some embodiments of the present invention, referring to Figure 1 Each audio unit 100 includes an audio housing 120 having a mounting panel 160 with mounting holes. A speaker 140 extends through the mounting holes and is fixedly connected to the audio housing 120. This facilitates assembly by allowing the speaker 140 to pass through the mounting holes and connect to the audio housing 120.

[0043] According to some embodiments of the present invention, referring to Figure 3 and Figure 5The audio unit 100 is provided with a speaker fixing member 170, which includes a first fixing portion 171 and a second fixing portion 172. The first fixing portion 171 is provided with a tangent surface tangent to the speaker portion of the speaker 140 and an edge slot. The tangent surface of the first fixing portion 171 is tangent to the speaker 140, and the edge slot is provided to hold the edge of the speaker 140. The second fixing portion 172 is fixedly connected to the non-speaker opening portion of the speaker 140. The first fixing portion 171 is fixedly connected to the second fixing portion 172. The first fixing portion 171 is provided with a tangent surface tangent to the speaker portion of the speaker 140, which can better fit the shape of the speaker 140. At the same time, the first fixing portion 171 is provided with an edge slot to hold the edge of the speaker 140, which can fix the speaker 140 and also serve as a limiter.

[0044] According to some embodiments of the present invention, referring to Figure 4 The speaker housing 120 includes a back panel that faces the side of the speaker 140. Each speaker unit 100 also includes a suspension member 130 that is disposed on the back panel and is fixedly connected to the back panel. The purpose of providing the back panel and the suspension member 130 is to allow the speaker to be suspended for use.

[0045] Specifically, in some embodiments, referring to Figure 6 , connect the suspension piece to the speaker and hang it on the ceiling, so that the speaker transmits sound toward the audience. It should be noted that the speaker with wide coverage can not only be hung on the ceiling, but also the hanging method and hanging position can be adjusted according to different occasions.

[0046] According to some embodiments of the present invention, referring to Figure 1 The speaker housing 120 is a trapezoidal column. The main purpose of setting the speaker housing 120 as a trapezoidal column is to form arc segments with preset angles when the speaker units 100 are tightly connected. The sound of the speaker is spread in a fan-shaped angle range, covering a wider range.

[0047] Specifically, in some embodiments, the trapezoidal angle of the trapezoidal columns of the speaker housing 120 can be adjusted to alter the sound distribution range of the speaker. In situations where increasing the number of speaker units 100 may be impractical due to space limitations, the sound coverage can be expanded by changing the angle of the trapezoidal columns of the speaker units 100. For example, if space limitations only allow for placement of three speaker units 100, the sound coverage can be expanded by changing the trapezoidal angle of the speaker housing 120.

[0048] According to some embodiments of the present invention, referring to Figure 2The sound absorbing member 150 is detachably connected to the mounting panel 160. The detachable connection between the sound absorbing member 150 and the mounting panel 160 includes adhesive connection, bolt connection, snap connection, etc. This facilitates the replacement of the sound absorbing member 150 and the cleaning of dust.
