[0030] like Figures 1 to 5 As shown, a speaker that can improve sound quality includes a cabinet 1, the cabinet 1 having a hollow structure, and the upper and / or lower end surfaces of the inner wall of the cabinet 1 having a plurality of spaced reflective grooves 11.

[0031] The speaker assembly 2 is disposed inside the enclosure 1. The front end of the enclosure 1 has a sound outlet 12, and the sound-emitting side of the speaker assembly 2 is located at the front end of the enclosure 1.

[0032] In addition to the speaker assembly 2 for sound generation, the cabinet 1 in this design also has reflective grooves 11 on the upper and lower surfaces of the inner wall of the cabinet 1. This changes the internal spatial structure of the cabinet 1. When the sound waves emitted by the speaker assembly 2 encounter the reflective grooves 11, they will be reflected, changing the reflection path of the sound waves inside the cabinet 1, thus improving the sound quality and timbre.

[0033] Furthermore, such as Figures 2 to 3 As shown, the audio component 2 includes a midrange module 21, a bass module 22 and a tweeter module 23. Several tweeter modules 23 are installed in the middle of the enclosure 1. At least one midrange module 21 is provided on each side of the tweeter module 23. The bass module 22 is provided on the outer side of the midrange module 21.

[0034] The audio component 2 includes a midrange module 21, a bass module 22, and a tweeter module 23. Each of the three speakers can be used to reproduce bass, midrange, and treble separately, making the sound more delicate and layered.

[0035] Furthermore, such as Figures 3 to 4As shown, the enclosure 1 has a mounting plate 13 and a first sound insulation plate 14 arranged in parallel. The mounting plate 13 is located in front of the first sound insulation plate 14, and both the mounting plate 13 and the first sound insulation plate 14 extend along the length of the enclosure 1. The mounting plate 13 has a plurality of sound outlet holes 12. The front ends of the bass module 22 and the midrange module 21 are installed at the sound outlet holes 12. The first sound insulation plate 14 has through holes 141 on both sides. The through holes 141 are directly opposite the rear end of the bass module 22. The tweeter module 23 is installed on the first sound insulation plate 14.

[0036] The interior of the enclosure 1 is also provided with two side panels 15. The two side panels 15 are located at the two ends of the mounting plate 13 and the first sound insulation plate 14, respectively. One end of the side panel 15 is connected to the mounting plate 13, and the other end of the side panel 15 is connected to the first sound insulation plate 14 and extends to its rear side. The mounting plate 13, the first sound insulation plate 14, and the two side panels 15 together form the first chamber 3.

[0037] The first chamber 3 is also provided with two second sound insulation panels 16. The two ends of the second sound insulation panels 16 are respectively connected to the mounting plate 13 and the first sound insulation panel 14. The second sound insulation panels 16 are located between the bass module 22 and the midrange module 21 to divide the first chamber 3 into a first partition 31 and two second partitions 32. The two bass modules 22 are respectively located in the corresponding second partitions 32, and the midrange module 21 is located in the first partition 31.

[0038] In this embodiment, the enclosure 1 has two tweeter modules 23 arranged vertically in the middle; two midrange modules 21 are arranged on each side of the tweeter modules 23, that is, there are a total of four midrange modules 21; and one woofer module 22 is arranged on each side of the midrange modules 21. The tweeter module 23 corresponds to the area directly opposite the rear of the first soundproofing plate 14; the woofer module 22 corresponds to the area directly opposite the rear of the second partition 32 and the through hole 141; and the midrange module 21 corresponds to the second partition 32. The three-way speaker with the above structure can extend the high, mid, and low frequencies, improve clarity, enrich the volume, and reduce distortion.

[0039] Furthermore, the inner wall of the enclosure 1 directly above or below the tweeter module 23 is not provided with the reflective groove 11, and the inner wall of the enclosure 1 directly above or below the rear side of the tweeter module 23 is not provided with the reflective groove 11. The front end of the tweeter module 23 is provided with a horn 231, and the front end of the horn 231 extends to the front end of the enclosure 1.

[0040] In this embodiment, the area corresponding to the tweeter module 23 is not provided with a reflective groove 11, but with a corresponding horn 231. The tweeter radiates to the sound coverage area through the horn 231, enhancing the sound pressure in the middle of the speaker.

[0041] Furthermore, the second sound insulation panel 16 is inclinedly disposed in the first chamber 3 so that the cross-section of the first partition 31 is trapezoidal.

[0042] In this embodiment, the second sound insulation plate 16 is inclined, so that the cross-section of the first partition 31 is a trapezoid with a narrow top and a wide bottom. The first partition 31 is a mid-range chamber, which can ensure that the sound-emitting area of ​​the mid-range module 21 is inclined towards the center of the cabinet 1 for sound amplification. The two mid-range modules 21 are symmetrically distributed on both sides of the high-range module 23. This structure is conducive to the response of the mid-range sound source and the high-range sound source, and the transmitted sound waves can synthesize a high-quality stereo effect.

[0043] Furthermore, the reflective groove 11 is elongated; at least one end of the reflective groove 11 is arc-shaped. The shape of the reflective groove 11 is preferably an elongated waist-shaped groove. The reflective groove 11 corresponding to the bass module 22 is longer, while the reflective groove 11 corresponding to the midrange module 21 is relatively shorter.

[0044] In other embodiments, the reflective groove 11 may also be rectangular or other shapes.

[0045] Furthermore, the spacing between two adjacent reflective grooves 11 is 9-10 mm, and the depth of each reflective groove 11 is 4-6 mm. When the depth of the reflective grooves 11 and the spacing between each reflective groove 11 are set within the above-mentioned preferred range, the reflection effect on sound waves is optimal, which can better improve the sound quality and timbre.

[0046] Furthermore, the first sound insulation plate 14 is also provided with a plurality of reflective protrusions 142 extending to the through hole 141. The plurality of reflective protrusions 142 provided at the through hole 141 can also play a certain reflective role, further improving the sound quality and timbre.

[0047] Furthermore, such as Figure 1 As shown, a dustproof mesh 17 is also provided on the front side of the enclosure 1, and the dustproof mesh 17 is located on the outside of the speaker assembly 2. The dustproof mesh 17 is provided on the front side of the enclosure 1 to prevent dust from entering the interior of the speaker through the various sound outlets 12. The dustproof mesh 17 does not affect the propagation of sound from the various modules of the speaker.

[0048] Furthermore, detachable handles 18 are provided on the exterior of both sides of the enclosure 1. In this embodiment, handles 18 are provided on both sides of the enclosure 1, making it easier for operators to move the speaker.

[0049] Furthermore, there is a gap between the two sides of the enclosure 1 and the side plate 15, so that the middle part of the two sides of the enclosure 1 is recessed inward to form a clearance position 19. In order to save more space, the handle 18 of this embodiment is set to fit against the two sides of the enclosure 1. However, during the process of moving the speaker, it is necessary to reserve a gripping position for the operator's hand or the robotic arm. Therefore, this embodiment also provides recessed clearance positions 19 on both sides of the enclosure 1.

[0050] In order to avoid the inward recessed clearance 19 from affecting the sound transmission effect inside the speaker, the sound transmission area of ​​this solution is mainly the space between the first chamber 3 and the two side plates 15. The two sides of the cabinet 1 and the side plates 15 are also reserved with gaps, so that the clearance 19 will not extend into the internal space of the side plates 15 while forming the clearance 19.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
