Description

Technical Field

[0001] The utility model relates to the technical field of sound boxes and microphones, in particular to a sound box body. Background Art

[0002] The handheld karaoke machine (commonly known as "Karaoke treasure") has both microphone and speaker functions. The structure of the speaker box directly affects the sound effect. The karaoke treasure in the prior art generally only has one speaker, and the sound wave coverage range of the speaker is small; some products are relatively equipped with two speakers. Although the sound wave coverage range on both sides is improved, the sound effect in the front is poor. In addition, the paper cone surface of the speaker is arranged vertically, and the sound waves emitted by the speaker can easily reach the sound head and interfere with the sound head, causing noise and other problems. Therefore, it is necessary to propose a new speaker box to further improve the sound effect of the handheld karaoke machine.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a speaker box, aiming to solve the technical problem in the prior art that the sound effect of the handheld karaoke machine needs to be further improved.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A speaker box body comprises a front box body and a rear box body, wherein the front box body is provided with two intersecting side surfaces, each side surface is provided with a speaker mounting hole, and the two speaker mounting holes are arranged in a front-to-back staggered manner; a passive panel mounting hole is provided on the rear box body; the top of the front box body and the top of the rear box body constitute an upper pipe, the upper pipe is provided with an external thread, and the top of the front box body and the bottom of the rear box body constitute a lower pipe.

[0007] Furthermore, in the speaker box, each speaker mounting hole is arranged obliquely downward, and the passive panel mounting hole is arranged obliquely downward.

[0008] Furthermore, in the speaker box, the angle between the two side surfaces of the front box is in the range of 50° to 60°.

[0009] Furthermore, in the speaker box, two side edges of the rear box are respectively provided with a guide groove.

[0010] Furthermore, in the speaker box, each guide groove is located in the middle of the rear box in the height direction.

[0011] Furthermore, in the speaker box, each guide groove is a straight groove.

[0012] Furthermore, in the speaker box, the front box and the rear box are connected by screws.

[0013] Beneficial effects: Compared with the prior art, the utility model provides a speaker box. Since the two sides of the front box are at a certain angle, the sound waves emitted by the two speakers can cover a certain range on the front side and both sides, thereby improving the coverage of the speaker sound waves. In addition, since the speaker mounting holes and the passive plate are arranged obliquely downward, the sound waves emitted by the speaker are emitted obliquely downward, the sound waves reaching the sound head are reduced, and the sound head picks up the sound more cleanly. By arranging the guide groove on the rear box, the sound effect is fuller and more concentrated. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model provides a speaker box. To make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] See also Figures 1 to 5 , the utility model provides a sound box body.

[0021] A speaker box body, comprising a front box body 1 and a rear box body 2. The front box body is provided with two intersecting side surfaces 11, each side surface is provided with a speaker mounting hole 100, and the two speaker mounting holes are arranged in a front-to-back staggered manner (i.e., in Figure 1 In the viewing angle, one speaker mounting hole is closer to the observer); a passive board mounting hole is provided on the rear box; the top of the front box and the top of the rear box constitute an upper pipe 3, which is provided with an external thread 31, and the top of the front box and the bottom of the rear box constitute a lower pipe 4. The upper pipe is convenient for connecting with the sound head 8, and the lower pipe is convenient for connecting with the handle (not shown in the figure).

[0022] The two speaker mounting holes are arranged in a staggered manner. Figure 1 In the viewing angle, one speaker mounting hole is closer to the observer. Similarly, in the top view, one speaker mounting hole is located further down. The distance between the two speaker mounting holes is preferably 1 to 2 mm. Since the two speaker mounting holes are offset front to back, after the speakers are installed, the two speakers are also offset front to back, which not only ensures that the sound effects in a certain range in front of and on both sides of the speaker are not affected, but also further improves the sound wave coverage of the speaker.

[0023] Furthermore, each speaker mounting hole is arranged obliquely downward, and the passive board mounting hole is arranged obliquely downward.

[0024] Furthermore, the angle between the two side surfaces of the front box body ranges from 50° to 60°.

[0025] Furthermore, a guide groove is provided on each of the two sides of the rear box. By providing the guide groove, the sound emitted by the passive panel can be output from the guide groove to the speaker side, forming a synchronous superposition with the sound waves of the speaker, making the sound performance more concentrated.

[0026] Preferably, each guide groove 201 is located in the middle of the rear box body in the height direction.

[0027] Preferably, each guide groove is a straight groove.

[0028] Preferably, the front box body and the rear box body are connected by screws.

[0029] In actual applications, each speaker mounting hole is equipped with a speaker 6, and the passive board mounting hole is equipped with a passive board 7. When in use, the passive board faces the user, and the two speakers are roughly facing the audience. Since the two sides of the front box are at a certain angle, the sound waves emitted by the two speakers can cover a certain range on the front side and both sides, thereby improving the coverage range of the speaker sound waves. In addition, since the speaker mounting holes and the passive board are arranged obliquely downward, the sound waves emitted by the speaker are emitted obliquely downward, and the sound waves reaching the sound head 8 are reduced, and the sound head picks up the sound more cleanly. By arranging a guide groove on the rear box, the sound effect is fuller and more concentrated.

[0030] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
