Description

Technical Field

[0001] The utility model relates to the technical field of speaker boxes, and in particular to a speaker box capable of improving sound effects. Background Art

[0002] A speaker is a device that people often use to produce sound. It has a wide range of applications, including concerts, conference rooms, KTVs, dance halls, homes and many other occasions.

[0003] For example, a Chinese patent application with the number 201720495481.7 and the publication date 2017.12.19 discloses a multimedia portable speaker, which is equipped with speakers with multiple sound frequencies on the box, including a mid-range speaker, a tweeter and a woofer.

[0004] For example, most existing speakers described in this document consist of a cabinet with a woofer, midrange speaker, and tweeter mounted within it. The tweeter and midrange speaker are located on either side of the woofer, each controlled by a crossover. Each speaker can only produce sound within a specific frequency range. While such speakers can meet the needs of audio playback to a certain extent, each frequency band is produced by a single speaker. The sound waves of the woofer and tweeter are different. If the tweeter is located to one side of the woofer, higher trebles are likely to appear on one side, resulting in poor sound mixing. Summary of the Invention

[0005] The utility model provides a speaker box capable of improving sound effects, wherein a tweeter and a woofer are arranged on the same straight line, so that the sounds emitted by the tweeter and the woofer are mixed well, thereby improving the sound effects.

[0006] To achieve the above-mentioned purpose, the present invention provides a speaker box capable of improving the sound effect, comprising a box body, a mounting groove provided in the center of the box body, a speaker provided in the mounting groove, the speaker comprising a woofer and a tweeter, the woofer being arranged in the center of the mounting groove, the tweeter being arranged in the mounting groove below the woofer and located on a vertical line of the woofer, mid-high-pitched speakers being further provided on both sides of the mounting groove, the mid-high-pitched speakers being located on a horizontal line of the tweeter.

[0007] The above setting, by arranging the tweeter below the woofer and on the vertical line of the woofer, makes the tweeter and the woofer coaxially arranged, so that the sound waves emitted by the tweeter and the woofer can be coaxially mixed. At the same time, due to the different sound wave waveforms emitted by the tweeter and the woofer, the radiation range of the woofer sound wave is large, and the radiation range of the tweeter is small, so that there are parts on both sides of the tweeter without treble sound waves, resulting in the tweeter and the woofer having a sound frequency off-axis effect on both sides of the tweeter. Therefore, by arranging mid-high frequency speakers on both sides of the horizontal line of the tweeter, the off-axis effect between the tweeter and the woofer can be compensated, and the sound effect of the speaker box is good.

[0008] Furthermore, a top cover is provided on the mounting groove, and a cavity is formed between the mounting groove and the top cover. The bottoms of the tweeter and the woofer are installed in the cavity, and the front ends of the tweeter and the woofer are located above the top cover.

[0009] The above arrangement, by providing a cavity, facilitates installation of the speaker, thereby saving space.

[0010] Furthermore, a tweeter mounting hole and a woofer mounting hole are provided on the top cover, the tweeter is arranged in the tweeter mounting hole, and the woofer is arranged in the woofer mounting hole.

[0011] The above arrangement facilitates the installation and fixation of the speaker through the arrangement of the speaker mounting holes.

[0012] Furthermore, one or more mounting posts are provided in the cavity, and mounting holes corresponding to the mounting posts are provided on the top cover, and the tweeter and woofer are mounted on the mounting posts by screws.

[0013] The above arrangement can ensure that the tweeter and the woofer are installed on the same axis and maintained at the same height through the arrangement of the mounting column, while facilitating the fixing of the speakers.

[0014] Furthermore, a mid-high frequency speaker mounting hole is provided on the top cover on the horizontal line of the tweeter mounting hole, and the mid-high frequency speaker is arranged in the mid-high frequency speaker mounting hole.

[0015] The above arrangement facilitates the installation and fixation of the mid-high frequency speaker through the arrangement of the mid-high frequency speaker mounting holes.

[0016] Furthermore, one or more reinforcing ribs are provided around the mounting column.

[0017] The above arrangement can enhance the strength of the mounting column.

[0018] Furthermore, the box body is provided with first mounting grooves on both sides of the mounting groove, wherein the mid-high frequency speakers are provided in the first mounting grooves, and a notch is provided on the first mounting groove, which is communicated with the cavity.

[0019] The above arrangement allows the sound waves emitted by the tweeter and woofer to mix in the cavity and then be mixed with the sound waves emitted by the mid-high frequency speaker before being emitted.

[0020] Furthermore, sound outlets are provided on the top cover at both ends of the woofer and on one side of the mid-range and tweeter.

[0021] The above settings make it easier for the tweeter and woofer to mix with the mid-high frequency speakers and emit sound waves. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0025] like Figure 1-2 As shown, a speaker capable of improving sound effects includes a box body 1, a mounting slot 11 is provided at the center of the box body 1, and a speaker is provided in the mounting slot 11, the speaker includes a woofer 21 and a tweeter 22, the woofer 21 is arranged at the center of the mounting slot 11, the tweeter 22 is arranged in the mounting slot 11 below the woofer 21 and is located on the vertical line α of the woofer 21, and mid-high frequency speakers 23 are further provided on both sides of the mounting slot 11, and the mid-high frequency speakers 23 are located on the horizontal line β of the tweeter 22.

[0026] A top cover 12 is provided on the mounting groove 11, and a cavity 10 is formed between the mounting groove 11 and the top cover 12. The bottoms of the tweeter 22 and the woofer 21 are mounted in the cavity 10, and the front ends of the tweeter 22 and the woofer 21 are located above the top cover 12. The provision of the cavity 10 facilitates the installation of the speakers and saves space.

[0027] The top cover 12 is provided with a tweeter mounting hole 13 and a woofer mounting hole 14. The tweeter 22 is disposed within the tweeter mounting hole 13, and the woofer 21 is disposed within the woofer mounting hole 14. A mid-high-range speaker mounting hole 15 is also provided on the top cover 12, horizontally from the tweeter mounting hole 13. The mid-high-range speaker 23 is disposed within the mid-high-range speaker mounting hole 15. The provision of the speaker mounting holes facilitates the installation and securing of the speakers. One or more mounting posts 16 are provided within the cavity 10, and two or more reinforcing ribs 161 are evenly spaced on the outer peripheral wall of the mounting posts 16. The speakers are mounted on the mounting posts 16 using screws (not shown). The provision of the mounting posts 16 facilitates the securing of the speakers.
