It should be noted that, in the present embodiment, the outer contour of the inner casing 11 is adapted to the shape of the inner contour of the outer casing 10, and thus the utilization rate of the accommodating space in the outer casing 10 can be significantly improved.
With continued reference to fig. 3-4, the housing 10 has a top end and a bottom end, the housing 10 has a structure with a small top end and a large bottom end, the side of the housing 10 is provided with a plurality of inclined sound outlet channels 101, the plurality of inclined sound outlet channels 101 are sequentially arranged on the side along the direction from the bottom end of the housing 10 to the top end of the housing 10, and the cross-sectional areas of the plurality of inclined sound outlet channels 101 become smaller gradually.
Specifically, with continued reference to fig. 5, in the present embodiment, the casing 10 may have a truncated cone structure, and the plurality of side sound outlet channels 101 are disposed around the sound generating assembly 12, that is, the plurality of side sound outlet channels 101 are disposed on the circumferential side surface of the casing 10. With this arrangement, a balanced sound field in a three-dimensional space can be created in the lower region of the sound emission device 100.
With continued reference to fig. 6, in other embodiments of the present invention, the housing 10 may have a frustum pyramid structure, and the side sound outlet channels 101 are located at two opposite sides of the sound emitting assembly 12, in which case the side sound outlet channels 101 are respectively opened at two waists of the frustum pyramid structure. By the arrangement, a balanced sound field can be formed in the range of 180 degrees in front of the sound generating device 100, listeners in the area can listen and feel consistently, and music appreciation experience is improved.
In both embodiments, with continued reference to fig. 3-4, the plurality of side sound-emitting channels 101 gradually decrease in distance from the central axis of the housing 10 in a direction from the bottom end of the housing 10 to the top end of the housing 10. That is, the side sound-emitting passages 101 closer to the center axis of the housing 10 have smaller cross-sectional areas, and the side sound-emitting passages 101 farther from the center axis of the housing 10 have larger cross-sectional areas. With this arrangement, high-frequency sounds at different angles can be suppressed to different degrees, and the farthest sound outlet channel 101 has the largest opening, thereby minimizing suppression of high frequencies.
Further, with reference to fig. 4, a plurality of front sound channels 102 are formed on the top surface of the housing 10, specifically, the front sound channels 102 are disposed obliquely upward relative to the center line of the sound emitting component 12, and the cross-sectional area of the front sound channels 102 is gradually increased in a direction away from the sound emitting component 12. The front sound-emitting channel 102 is located right in front of the sound-emitting component 12, and is used for controlling the loudness of high-frequency sound in a right-front area, so that the high-frequency sound in the range is suppressed to be basically consistent with the side sound-emitting channel 101, and the purpose of sound field equalization is achieved.
It is worth mentioning that the opening of the front sound emission channel 102 is small, and even the front sound emission channel 102 may be eliminated, depending on the high frequency performance of the speaker. It should be noted that the larger the opening of the front sound emission duct 102 is, the smaller the suppression of the high-frequency sound directed directly forward is, and the smaller the opening is, the larger the suppression of the high-frequency sound directed directly forward is, and the suppression of the high-frequency performance of the speaker becomes strongest when it is completely cancelled.
With continued reference to fig. 3-4, the side surface of the housing 10 is provided with 4 side sound outlet channels 101, and for convenience of description, the 4 side sound outlet channels 101 are respectively defined as a first side sound outlet channel, a second side sound outlet channel, a third side sound outlet channel and a fourth side sound outlet channel along the direction from the bottom end to the top end of the housing 10, wherein the first side sound outlet channel is a bottommost side sound outlet channel and is disposed obliquely toward the direction close to the bottom end of the housing 10, that is, the first side sound outlet channel is disposed obliquely downward, and the second side sound outlet channel, the third side sound outlet channel and the fourth side sound outlet channel are disposed obliquely toward the direction close to the top end of the housing 10. That is, the second side sound emitting channel, the third side sound emitting channel, and the fourth side sound emitting channel are arranged in an obliquely upward direction.
