DETAILED DESCRIPTION

[0024] The utility model discloses a horn-type bookshelf speaker, which is described in conjunction with the preferred embodiment (Example 1) and the accompanying drawings. Figure 1-5 , the specific implementation methods of the utility model are further described.

[0025] See attached figure Figures 1 to 5 , Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The visual structures at different viewing angles are shown. Figure 2 Shown along Figure 1 Cross-sectional structure in the AA direction.

[0026] Example 1.

[0027] Preferably, the horn-type bookshelf speaker is used for playing home music, and includes a floor stand 100 and a box 200, wherein the floor stand 100 and the box 200 are detachably connected. The horn-type bookshelf speaker further includes:

[0028] The midrange sound-producing structure 300 is located at the top of the cabinet 100 and is completely external to the cabinet 100. The midrange sound-producing structure 300 is detachably connected to the top plate 201 of the cabinet 100. The midrange sound-producing structure 300 includes a horn-shaped basket 301 and a voice coil 302. The basket contraction end 3011 of the horn-shaped basket 301 is in contact with the voice coil 302. The cross-sectional diameter (located in the vertical plane) of the basket open end 3012 is much larger than the cross-sectional diameter (located in the vertical plane) of the basket contraction end 3011. This allows the basket open end 3012 (sound outlet) of the horn-shaped basket 301 to have a smooth arc angle, thereby achieving a better midrange sound effect.

[0029] The bass sound generating structure 400 is embedded in the front panel 202 of the box 200;

[0030] The tweeter sounding structure 500 is embedded in the front panel 202 of the box 200. There is no (physical) contact between the woofer sounding structure 400 and the tweeter sounding structure 500 (obviously, there is also no contact between the midrange sounding structure 300 and the woofer sounding structure 400 and the tweeter sounding structure 500). The tweeter sounding structure 500 is located between the midrange sounding structure 300 and the woofer sounding structure 400, so that the midrange sounding structure 300, the woofer sounding structure 400 and the tweeter sounding structure 500 of the horn-type bookshelf speaker of the present application are designed to be separated from each other, so that the sound restoration of each sound zone is better.

[0031] The mid-range sound-producing structure 300 further includes a cylinder 303 and a front cover 304 . The voice coil 302 is sleeved on (and externally connected to) the front cover 304 . The front cover 304 is partially internally connected to one end of the cylinder 303 , so that the front cover 304 closes the open end of the cylinder 303 .

[0032] The mid-range sound-producing structure 300 further includes a support frame 305 . The support frame 305 is built into the cylinder 303 , and the outer surface of the support frame 305 is in contact with the inner surface of the cylinder 303 .

[0033] Among them, the mid-range sound-producing structure 300 also includes a base 306, which is fixedly connected to the top plate 201 and detachably connected to the cylinder 303, so that the mid-range sound-producing structure 300 and the top plate 201 of the box body 100 are detachably connected as a whole.

[0034] The mid-range sound structure 300 further includes a magnetic block 307 , which is built into the support frame 305 , with a gap between the magnetic block 307 and the support frame 305 , and the magnetic block 307 contacts the end face of the front cover 304 away from the voice coil 302 .

[0035] The cylinder 303, the front cover 304 and the base 306 are preferably formed by pressing stainless steel.

[0036] The outer surfaces of the horn-shaped basin frame 301, the cylinder 303, the front cover 304, and the base 306 are preferably coated respectively, so as to improve the overall aesthetics and prevent corrosion.

[0037] The horn-shaped basin frame 301 is preferably made of cast aluminum, which has the characteristics of fast heat dissipation and low distortion.

[0038] The outer surface of the voice coil 302 has a nano-composite coating to achieve a high-temperature resistant neodymium magnetic circuit design, thereby reducing distortion and ensuring clear sound quality.

[0039] The voice coil 302 is wound with high-temperature resistant copper-clad aluminum wire.

[0040] The magnetic block 307 preferably adopts a Y40 magnet to provide a strong output power.

[0041] The tweeter sounding structure 500 includes a tweeter bracket 501 , a pressure block 503 is provided on one side of the tweeter bracket 501 , and a tweeter diaphragm 502 and a tweeter basin frame 504 are provided on the other side of the tweeter bracket 501 to achieve a complete treble sounding function.

[0042] Among them, the tweeter diaphragm 502 is pressed from a carbon fiber composite silk membrane (1" 25.4 core carbon fiber composite silk membrane), which improves the rigidity and damping of the treble, making the sound quality delicate and pure, with a higher degree of restoration.

[0043] Among them, the bass sound-generating structure 400 includes a bass diaphragm 401. The diaphragm 401 (cone, cloth edge) is pressed from a variety of fibers and has the characteristics of strong rigidity and good damping. It can effectively increase bass radiation and make low-frequency sound effects richer.

[0044] Example 2.

[0045] The difference between Example 2 and Example 1 is that the "cross-sectional diameter of the open end 3012 of the basin frame (located in the vertical plane) is much larger than the cross-sectional diameter of the contracted end 3011 of the basin frame (located in the vertical plane)" in Example 1 is modified to "the cross-sectional diameter of the open end 3012 of the basin frame (located in the vertical plane) is larger than the cross-sectional diameter of the contracted end 3011 of the basin frame (located in the vertical plane)".

[0046] It is worth mentioning that the technical features such as the specific selection of fibers of the diaphragm 401 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by conventional means in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.

[0047] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
