[0002] As a widely used audio solution in home theaters, commercial spaces and public places, ceiling speakers have the advantages of saving space and being neat and tidy. Some ceiling speaker components include separate tweeters and woofers, which has obvious advantages in providing a wider frequency range and more delicate audio performance. However, this configuration also brings some problems, especially the different angles covered by sound waves of different frequencies, resulting in uneven coverage of sound waves of different frequencies of the speaker.

[0003] High-frequency audio and low-frequency audio have obvious directivity differences in space. High-frequency audio has stronger directivity due to its short wavelength, while low-frequency sound is easier to diffuse in space due to its long wavelength. This difference affects the directional balance of ceiling speaker components over a wide frequency range from low frequencies to high frequencies.

The same or similar reference numerals in the various figures represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0030] In this document, the term "axis" refers to the axis x of the speaker assembly, that is, the common axis of the first speaker and the second speaker of the speaker assembly. The term "axial" or "axial direction" refers to the direction along the axis of the speaker assembly, the term "circumferential" refers to the direction around the axis x, the term "radial" or "radial direction" refers to the direction generally perpendicular to the axis, pointing to or away from the axis, the term "radial inside" or "radial inside" refers to a component, part, position or direction relatively close to the axis, and the term "radial outside" or "radial outside" refers to a component, part, position or direction relatively far from the axis.

[0031] The utility model provides a loudspeaker assembly, which comprises a shell and a panel, and comprises a woofer and a tweeter arranged in a containing space defined by the shell and the panel, the panel is formed with a plurality of openings and a horn portion in an expansion shape, a first loudspeaker is acoustically connected to the plurality of openings, and a second loudspeaker is arranged adjacent to the panel and acoustically connected to the horn portion.

[0032] The horn on the panel helps guide the high-frequency audio signal from the tweeter so that it spreads more evenly at the desired angle, thereby better matching the audio signal from the woofer in terms of directivity, so that the speaker assembly can achieve more uniform directivity in a wider frequency band from low frequency to high frequency, improving the user experience.

[0033] According to one or more embodiments of the present invention, the openings are evenly spaced around the horn and have a first section extending circumferentially and a second section radially extending from the first section toward the horn at one end of the first section.

[0034] The first section and the second section of each opening are both long. Such an opening structure achieves a larger total opening area with a smaller opening width. The total opening area of ​​the panel ensures that a sufficient amount of low-frequency audio from the woofer passes through, while the smaller opening width ensures that the high-frequency audio from the woofer or most of the high-frequency audio can be filtered out, thereby improving the overall sound quality of the speaker assembly.

[0035] According to one or more embodiments of the utility model, the speaker assembly further includes an audio cover arranged between the woofer and the tweeter. The audio cover includes a plurality of holes formed therein. The speaker assembly further includes a sponge formed between the audio cover and the panel, radially outside the second speaker.

[0036] The presence of the audio cover can separate and guide the low-frequency audio generated by the woofer and the high-frequency audio generated by the tweeter, which helps the speaker assembly provide excellent sound quality over a wide frequency range from bass to treble. In addition, the multiple holes and sponges on the audio cover help provide adjustment and buffering during the vibration of the woofer, reduce pressure fluctuations, and improve sound quality.

[0037] Figure 1A A 3D view of a speaker assembly 100 according to one or more embodiments of the utility model is shown. The speaker assembly 100 includes a housing 110 and a panel assembly 120. The housing 110 and the panel assembly 120 are connected to define an internal accommodation space. In the embodiment shown in the figure, the housing 110 is connected to the panel assembly 120 by a fastener (e.g., a bolt 116). In one or more other embodiments, the housing 110 may be connected to the panel assembly 120 by any suitable connection structure. The panel assembly 120 includes a panel 122 and a clamping mechanism 124. The panel 122 includes a flange portion 122a extending beyond the housing 110 in a radial direction. When in use, the clamping mechanism 124 clamps a ceiling (not shown) between the clamping portion 124a of the clamping mechanism 124 and the flange portion 122a of the panel 122, thereby fixing the speaker assembly 100 to the ceiling. In one or more other embodiments, the speaker assembly 100 may be connected to the ceiling by any suitable connection structure. In one or more other embodiments, the speaker assembly may not be limited to a ceiling speaker assembly, but may be any other suitable speaker assembly.

[0038] Figure 1B yes Figure 1A1 is an exploded view of the speaker assembly 100 shown in FIG. The speaker assembly 100 also includes a first speaker 150, an audio cover 160, a sponge portion 170, and a second speaker 180 contained in an internal accommodation space defined by the housing 110 and the panel assembly 120. The first speaker 150 and the second speaker 180 each include a magnetic circuit assembly, a frame, and a vibration assembly. The vibration assembly includes a diaphragm (diaphragm assembly) and a voice coil connected to the diaphragm (diaphragm assembly). The voice coil is at least partially suspended in the magnetic gap of the magnetic circuit assembly. When an audio electrical signal flows through the voice coil, the voice coil vibrates in the magnetic gap under the action of the magnetic field, thereby driving the diaphragm to vibrate and emit sound. The structure and working mode of the speaker are known in the art and will not be repeated here. In one or more embodiments, the first speaker 150 has a larger volume and diaphragm size, and belongs to a woofer, while the second speaker 180 has a smaller volume and diaphragm size, and belongs to a tweeter. The combination of the woofer and the tweeter can provide the speaker assembly 100 with excellent sound quality in a wide frequency range from bass to treble. In one or more other embodiments of the present invention, the first speaker 150 and the second speaker 180 are not limited to a woofer and a tweeter, as long as the second speaker is more suitable for reproducing audio in a higher frequency band than the first speaker 150. Compared with the solution using a single speaker, the combination of the first speaker 150 and the second speaker 180 can provide the speaker assembly 100 with excellent sound quality in a wider frequency range.

[0039] Figure 2A A cross-sectional view of a speaker assembly 100 according to one or more embodiments of the present invention is shown. Figure 2B yes Figure 2A 2B is an enlarged view of the dotted line portion 2B. The speaker assembly 100 has an axis x. The first speaker 150 and the second speaker 180 are coaxially arranged or substantially coaxially arranged along the axis x of the speaker 100, and the two are spaced apart from each other. The second speaker 180 is arranged on the axial front side of the first speaker 150, adjacent to the panel 122. A horn 130 is formed on the panel 122, and the horn 130 has a central opening. The horn 130 and the central opening of the panel 122 are coaxially arranged or substantially coaxially arranged with the first speaker 150 and the second speaker 180 along the axis x of the speaker 100. The horn 130 gradually expands in the axial forward direction of the speaker assembly 100. In the embodiment shown in the figure, the horn 130 is in the shape of a truncated cone. The angle between the horn 130 and the axis x can be set as needed. In some embodiments, the angle between the horn 130 and the axis x can be, for example, between 35-70 degrees. In one or more other embodiments, the horn 130 can have a trumpet shape or other expansion shape. The diaphragm 182 of the second speaker 180 is aligned with the central opening of the horn 130 and at least partially extends from the central opening of the horn 130 .

[0040] As is known in the art, the high-frequency audio signal emitted by the second speaker 180 has a stronger or narrower directivity than the lower-frequency audio signal emitted by the first speaker 150. The horn portion 130 on the panel 122 helps guide the high-frequency audio signal emitted by the second speaker 180 so that it spreads more evenly at a desired angle. The audio signal guided by the second speaker 180 through the horn portion 130 can better match the audio signal of the first speaker 150 in terms of directivity, so that the speaker assembly 100 can achieve more uniform directivity over a wider frequency range from low frequency to high frequency, thereby improving the user experience of the user.

[0041] The speaker assembly 100 further includes an audio cover 160 disposed between the first speaker 150 and the second speaker 180. The audio cover 160 is also disposed coaxially with the first speaker 150 and the second speaker 180 along the axis x of the speaker 100. The audio cover 160 has a shape that generally conforms to the diaphragm assembly 152 (including the diaphragm 154, the optional dust cover 156, and the optional folding ring 158) of the first speaker 150, thereby defining an audio channel 168 between the first speaker 150 and the audio cover 160. The audio cover 160 further includes a plurality of holes 162. The audio cover 160 further includes a plurality of vacant portions (recesses) 164 (see FIG. 1 ) extending from the radial outer periphery of the audio cover 160 in a radially inward direction. Figure 1B ).

[0042] The presence of the audio cover 160 can separate and guide the low-frequency audio generated by the first speaker 150 and the high-frequency audio generated by the second speaker 180 of the speaker assembly 100, respectively, which helps the speaker assembly 100 provide excellent sound quality over a wide frequency range from bass to treble. In addition, the multiple holes 162 and the sponge 170 on the audio cover 160 help provide adjustment and buffering during the vibration of the woofer 150, reduce the pressure fluctuation inside the speaker assembly 100, such as at the audio channel 168, and improve the sound quality.

[0043] Figure 3A A 3D view of a speaker assembly 100 according to one or more embodiments of the present invention is shown, which mainly shows a panel 122 of a panel assembly 120 of the speaker 100 . Figure 3BA bottom view of the speaker assembly 100 is shown. As shown, the panel 122 is circular, and the horn 130 is formed at a substantially central position thereof. The diaphragm 182 of the second speaker 180 is aligned with the central opening of the horn 130, and at least partially extends or is exposed from the central opening of the horn 130. Thus, the horn 130 of the panel 122 helps to guide the high-frequency audio signal emitted by the second speaker 180 so that it is more evenly propagated at a desired angle. The horn 130 enables the directivity of the high-frequency audio of the second speaker 180 to better match the audio signal of the first speaker 150, thereby enabling the speaker assembly 100 to achieve more uniform directivity over a wider frequency band from low frequency to high frequency.

[0044] The panel 122 is also formed with a plurality of openings 140 arranged around the horn 130. In the embodiment shown in the figure, the panel 122 includes 8 openings 140 evenly spaced around the horn 130. In one or more other embodiments according to the present invention, the number of openings 140 on the panel 122 can be more than 8 or less than 8, such as 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16.

[0045] Each opening 140 of the panel 122 includes a first section 142 extending in the circumferential direction and a second section 144 extending radially inward from one end of the first section, forming a "7" or "L" shape. In one or more other embodiments according to the present invention, the opening 140 of the panel 122 is not limited to the "7" or "L" shape as shown in the figure, but may adopt any other suitable shape. For example, the second section 144 of the opening 140 may not extend radially inward from one end of the first section 142, but may extend radially inward from the middle position of the first section 142, thereby forming a general "T" shape.

[0046] In the embodiment shown in the figure, the first section 142 of each opening 140 of the panel 122 is arranged on the audio cover 160 (see Figure 2A and Figure 2B ) radially outwardly, and the audio channel 168 (see Figure 2B ) are connected, so that the audio generated by the first speaker 150 can leave the panel 122 of the speaker assembly 100 through the audio channel 168 and the first section 142 of the opening 140. The second section 144 of each opening 140 is arranged at the gap 164 (see Figure 1B ) at a position corresponding to the first speaker 150, so that the audio generated by the first speaker 150 can also leave the panel 122 of the speaker assembly 100 through the audio channel 168, the blank portion 164 of the audio cover 160 and the second section 144 of the opening 140.

[0047] In the embodiment shown in the figure, each opening 140 of the panel 122 is formed to have a first section 142 and a second section 144, and the first section 142 and the second section 144 of each opening 140 are both long strips. Such an opening 140 structure forms a larger total opening area (opening ratio) with a smaller opening width (the widths of the first section 142 and the second section 144 are both smaller). The total opening area (opening ratio) of the opening 140 of the panel 122 ensures that a sufficient amount of low-frequency audio from the first speaker 150 passes through, while the smaller opening width ensures that the high-frequency audio from the first speaker 150 or most of the high-frequency audio can be filtered out. Since the first speaker 150 is a woofer, it is more suitable for reproducing low-frequency audio. Filtering out or substantially filtering out the high-frequency audio generated by the first speaker 150 can effectively improve the overall sound quality of the speaker assembly 100.

[0048] In addition, since the voice coil of the first speaker 150 is connected to the radial inner edge of the diaphragm 154, the radial outer portion of the diaphragm assembly 152 or the diaphragm 154 of the speaker 150 is far away from the voice coil, and the high-frequency vibration generated by the voice coil is not easily transmitted to the radial outer portion of the diaphragm assembly 152 or the diaphragm 154. That is, compared with the radial inner portion of the diaphragm assembly 152 or the diaphragm 154 of the first speaker 150, the sound generated by the radial outer portion of the diaphragm assembly 152 or the diaphragm 154 will contain less high-frequency components. In the illustrated embodiment, the first section 142 of each opening 140 of the panel 122 is formed on the radial outer side, and the second section 144 extends radially inward from the first section 142. Such a structure of the openings 140 allows more opening areas of the openings 140 to be formed at larger radial dimensions, thereby facilitating the passage of the sound generated by the radially outer portion of the diaphragm assembly 152 or the diaphragm 154, while filtering more of the sound generated by the radially inner portion of the diaphragm assembly 152 or the diaphragm 154, especially the high-frequency components of the sound. Since the first speaker 150 is a woofer, which is suitable for reproducing low-frequency audio, such an opening arrangement further effectively improves the overall sound quality of the speaker assembly 100.

[0049] In the embodiment shown in the figure, the first speaker 150 is a woofer, and the second speaker 180 is a tweeter. In the present invention, the woofer and the tweeter are relative concepts. That is, the diaphragm size of the first speaker 150 is larger than the diaphragm size of the second speaker 180, and the audio frequency band suitable for reproduction of the first speaker 150 is lower than the audio frequency band suitable for reproduction of the second speaker. In one or more embodiments according to the present invention, the diaphragm size or diameter of the first speaker 150 is twice or more the diaphragm size or diameter of the second speaker. In one or more other embodiments according to the present invention, the diaphragm size or diameter of the first speaker 150 is three, four, five or more times the diaphragm size or diameter of the second speaker.

[0050] In the embodiment shown in the figure, the panel 122 of the speaker assembly 100 is formed with a horn portion 130 and a "7" or "L" shaped opening 140, and the speaker assembly 100 also includes an audio cover 160 and a sponge 170. The utility model is not limited to this. In one or more embodiments according to the utility model, the speaker assembly 100 may not include the audio cover 160 and / or the sponge 170. In one or more other embodiments according to the utility model, the size and position of the opening 140 of the speaker assembly 100 may not be limited to those shown in the figure. In one or more other embodiments according to the utility model, the speaker assembly 100 may not include the horn portion 130.

The speaker assembly 200 also includes a first speaker 250, an audio cover 260, a sponge portion 270, and a second speaker 280 accommodated in the internal accommodation space defined by the housing 210 and the panel assembly 220.

[0053] The panel assembly 220 includes a panel 222. The panel 222 is circular and has a horn 230 formed thereon. The horn 230 is located at a position deviated from the center of the panel 222. The diaphragm 282 of the second speaker 280 is aligned with the central opening of the horn 230 and at least partially extends or is exposed from the central opening of the horn 230. The panel 222 is also formed with a plurality of openings 240 arranged around the horn 230. In the embodiment shown in the figure, the panel 222 includes 6 openings 240 evenly spaced around the horn 230. In one or more other embodiments according to the present invention, the number of openings 240 on the panel 122 may be more than 6 or less than 6.

[0054] Figure 4-5B The speaker assembly 200 is shown with Figure 1A-Figure 3BThe main difference of the speaker assembly 100 shown is that the size of the first speaker 250 of the speaker assembly 200 is smaller than the first speaker 150 of the speaker assembly 100. Accordingly, the number and shape of the openings 240 on the panel 222 are also changed accordingly.
