[0032] The following further elaborates on the embodiments of the present utility model in conjunction with the accompanying drawings.

[0033] Refer to Figures 1 to 3 As shown in [Figure number not provided], the high-frequency direction-controlled sound box 100 according to the first aspect embodiment of the present utility model comprises a sound box housing 140, a loudspeaker 130 and a sound absorption component 120. The sound box housing 140 is provided with an installation panel 141, and an installation hole 145 is arranged on the installation panel 141; the loudspeaker 130 passes through the installation hole 145 and is fixedly connected with the sound box housing 140; the sound absorption component 120 is detachably connected with the installation panel 141; wherein, the sound absorption component 120 comprises a first sound absorption body 121 and a second sound absorption body 122 which are arranged in parallel and on both sides of the sound wave output direction of the loudspeaker 130 respectively; a part of the structure of the first sound absorption body 121 covers a part of the opening of the loudspeaker 130, and a part of the structure of the second sound absorption body 122 covers a part of the opening of the loudspeaker 130.

[0034] The high-frequency direction-controlled sound box 100 provided by the embodiment of the present utility model is provided with a loudspeaker 130 and a sound absorption component 120. The sound absorption component 120 comprises a first sound absorption body 121 and a second sound absorption body 122 which are arranged in parallel. The first sound absorption body 121 and the second sound absorption body 122 cover a part of the opening of the loudspeaker, determining the target output direction, so that the high-frequency signal generated by the loudspeaker 130 is output along the target output direction from the unobstructed part. Therefore, the present utility model can control the output direction of the high-frequency signal of the sound box, make the propagation of the high-frequency signal more concentrated, effectively reduce the noise pollution and interference, and improve the signal quality.

[0035] Refer to Figure 1, the sound absorption component 120 has two sound absorbers, namely a first sound absorber 121 and a second sound absorber 122. The two sound absorbers respectively cover part of the opening of the speaker, thereby determining the target output direction. The first sound absorber 121 and the second sound absorber 122 absorb the high-frequency signals output from the part of the opening of the covered speaker 130, and the unabsorbed high-frequency signals are output along the target output direction from the uncovered opening, realizing the directional propagation of high-frequency signals, making the propagation of high-frequency signals more concentrated, effectively reducing noise pollution and interference, and improving the signal quality.

[0036] In some embodiments, the sound absorption component 120 may be an integral sound absorber. That is to say, the first sound absorber 121 and the second sound absorber 122 may be an integral body. When the sound absorber is an integral body (not shown in the drawings), it should be set that there is a connecting part around the first sound absorber 121 and the second sound absorber 122, or a space is hollowed out in the central part of a whole sound absorber, which can partially cover the speaker and make the high-frequency sound propagate directionally from the unobstructed part. Such a setting can also have the above technical effects.

[0037] Refer to Figure 1 , according to some embodiments of the present invention, the first sound absorber 121 and the second sound absorber 122 of the sound absorption component 120 respectively cover the upper and lower parts of the opening of the speaker 130, thereby determining the target output direction of the high-frequency signal.

[0038] According to some embodiments of the present invention, the first sound absorber 121 may be arranged on the left side of the opening of the speaker 130, and the second sound absorber 122 may be arranged on the right side of the opening of the speaker 130, thereby determining the target output direction of the high-frequency signal.

[0039] It should be noted that as Figure 4 shown, in the case where the sound absorption component is not provided, the high-frequency signals output by the speaker radiate and propagate outward, and the corresponding sector angle a of the fan-shaped radiation range of the high-frequency signals in the vertical direction is 90 degrees. And when the sound absorption component is provided in the audio, after the upper and lower sides of the speaker 130 are partially covered, the situation of the high-frequency signals output by the speaker radiating and propagating outward is as Figure 5 shown, the corresponding sector angle a of the fan-shaped radiation range of the high-frequency signals in the vertical direction is less than 90 degrees, and in the horizontal direction, the corresponding sector angle a of the fan-shaped radiation range of the high-frequency signals is still 90 degrees.

[0040] It can be understood that the covering position of the sound absorption component 120 can be adjusted. The covering position and the size of the covering area of the sound absorption component 120 can be adjusted according to the actual situation.
