Description

Technical Field

[0001] Some embodiments of the present application relate to the field of audio technology, and more particularly to a cover assembly of an audio system and an audio system. Background Art

[0002] Sound bars, also known as "sounding walls," are popular among users for their ease of use and are ideal for pairing with TVs.

[0003] Traditional soundbars have side-mounted woofers with a sound channel located in front of the woofer's oscillator. This results in significant variations in the reflective surface area when the soundbar is positioned differently, leading to significant variations in bass quality. To address this issue, a related technology employs a cover plate in front of the woofer, which allows sound to propagate and diffuse in multiple directions around the plate. However, this requires creating a sound channel in the direction of sound propagation. Therefore, it is crucial to ensure structural strength at the sound channel while avoiding significant airflow noise. Utility Model Content

[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0042] In some embodiments, as Figures 1 to 4 As shown, the present application provides a cover assembly for a speaker. The speaker includes a vibrator 6 and the above-mentioned cover assembly. The vibrator 6 can also be called a speaker.

[0043] In some embodiments, the cover assembly of the speaker includes a cover structure 1, which includes a first mounting plate 11 and a second plate spaced apart in a first direction. A through hole 101 is provided on the cover structure 1, which passes through the first mounting plate 11 and the second mounting plate 12. The vibrator 6 can be installed on the first mounting plate 11 and face the through hole 101. A plurality of sound output channels 102 are formed between the first mounting plate 11 and the second mounting plate 12, which are spaced apart circumferentially along the through hole 101, and two of the sound output channels 102 are arranged opposite to each other.

[0044] The cover assembly of the speaker further includes a baffle 2, which is mounted on the second mounting plate 12 and covers the through hole 101. In this way, the sound emitted by the vibrator 6 can be blocked by the baffle 2 and then propagated and diffused in different directions through the multiple sound outlet channels 102.

[0045] The cover assembly of the speaker also includes a supporting rib 3, which is supported between the first mounting plate 11 and the second mounting plate 12 and is located in the sound outlet channel 102. The inner end of the supporting rib 3 is located on the outside of the hole wall of the through hole 101 and / or the outer end of the supporting rib 3 is located on the inside of the outer edge of the first mounting plate 11 and on the inside of the outer edge of the second mounting plate 12.

[0046] It should be noted that in the length direction of the sound outlet channel 102, the outer end of the support rib 3 is away from the through hole 101 relative to the inner end of the support rib 3, the inner edge of the first mounting plate 11 constitutes the hole wall surface of the through hole 101, and the inner edge of the second mounting plate 12 also constitutes the hole wall surface of the through hole 101.

[0047] The inner end of the support rib 3 being located outside the wall surface of the through hole 101 means that there is a certain distance between the inner end of the support rib 3 and the wall surface of the through hole 101. The outer end of the support rib 3 being located inside the outer edge of the first mounting plate 11 and inside the outer edge of the second mounting plate 12 means that there is a certain distance between the outer end of the support rib 3 and the outer edge of the first mounting plate 11 and the outer edge of the second mounting plate 12.

[0048] It can be understood that the sound outlet channel 102 is divided into at least two parts from the inside out, and the support ribs 3 in the sound outlet channel 102 are located in one of the parts of the sound outlet channel 102 or between the two outermost parts. That is to say, in the length direction of the sound outlet channel 102, the support ribs 3 are shorter than the sound outlet channel 102. This can avoid the setting of the support ribs 3 causing the sound outlet channel 102 to be divided into a narrow and long channel, that is, a channel with a smaller cross-sectional area. In this case, there are three situations for the setting of the support ribs 3. For example, the sound outlet channel 102 is divided into a first sound outlet channel and a second sound outlet channel from the inside out. The support ribs 3 can be located in the first sound outlet channel, or in the second sound outlet channel, or partly in the first sound outlet channel and partly in the second sound outlet channel, thus ensuring that the length of the support ribs 3 is shorter than the sound outlet channel 102.

[0049] It can also be understood that the support rib 3 is located in the sound outlet channel 102 , but in the length direction of the sound outlet channel 102 , the length of the support rib 3 is smaller than the length of the sound outlet channel 102 at the location.

[0050] The first mounting plate 11 is an annular structure with a central opening. The width of the first mounting plate 11 refers to the distance from the inner side to the outer side of the first mounting plate 11, wherein the outer side of the first mounting plate 11 is away from the through-hole 101. In this case, the length of the support rib 3 is less than the width of the first mounting plate 11 at the location of the support rib 3. Similarly, the second mounting plate 12 is also an annular structure with a central opening. In this case, the width of the second mounting plate 12 refers to the distance from the inner side to the outer side of the second mounting plate 12. The outer side of the second mounting plate 12 is away from the through-hole 101. In this case, the length of the support rib 3 is less than the width of the second mounting plate 12 at the location of the support rib 3.

[0051] It can be understood that the vibrator 6 is mounted on the first mounting plate 11 and faces the through hole 101, and the baffle 2 is mounted on the second mounting plate 12. A plurality of sound outlet channels 102 are formed between the first mounting plate 11 and the second mounting plate 12, spaced apart along the circumference of the through hole 101. In this way, the baffle 2 allows the sound emitted by the vibrator 6 to be emitted from the plurality of sound outlet channels 102, so that the sound can be propagated and diffused in different directions, thereby improving the listening effect. The provision of the support ribs 3 not only supports the first mounting plate 11 and the second mounting plate 12, thereby improving the structural strength and thus the durability and transportation strength of the sound system, but also avoids resonance with the frequency of the vibrator 6 and avoids sound distortion. Moreover, since the inner ends of the support ribs 3 do not protrude from the wall surface of the through hole 101 and / or the outer ends of the support ribs 3 do not protrude from the outer edges of the first mounting plate 11 and the second mounting plate 12, adjacent support ribs 3 are prevented from separating the sound outlet channels 102 into narrow and long channels, thereby reducing wind noise, avoiding obvious airflow sounds, and ensuring the listening effect.

[0052] In some embodiments, to improve the overall strength of the cover structure 1, the first mounting plate 11, the second mounting plate 12, and the support ribs 3 can be integrally formed. This can reduce the number of parts, ease assembly difficulty, and eliminate the need for additional fixing structures, thereby reducing costs.

[0053] Optionally, in other embodiments, one of the first mounting plate 11 and the second mounting plate 12 is detachably connected to the support rib 3. This can reduce production difficulty, facilitate replacement of the first mounting plate 11 and the second mounting plate 12, and reduce maintenance costs. For example, the first mounting plate 11 and the support rib 3 are detachably connected, and the support rib 3 and the second mounting plate 12 are integrally formed, or the second mounting plate 12 and the support rib 3 are detachably connected, and the support rib 3 and the first mounting plate 11 are integrally formed.

[0054] In some embodiments, reference Figure 3 and Figure 4 The first mounting plate 11 is recessed in the middle along its length to form a groove. The second mounting plate 12 is arranged opposite to the groove, and two sound outlet channels 102 are enclosed between the second mounting plate 12 and the groove of the first mounting plate 11. The two sound outlet channels 102 are arranged on both sides of the through hole 101 along the width direction of the first mounting plate 11.

[0055] Understandably, two sound outlet channels 102 are formed between the first mounting plate 11 and the second mounting plate 12, one on either side of the through hole 101 in the width direction of the first mounting plate 11. In other words, two sound outlet channels 102 are formed between the first mounting plate 11 and the second mounting plate 12, and the two sound outlet channels 102 are arranged opposite each other in the width direction of the first mounting plate 11. This allows the sound emitted by the vibrator 6 to be transmitted and diffused to both sides in the width direction of the first mounting plate 11 through the action of the baffle 2, thereby improving the listening experience when the speaker is placed in different positions. Furthermore, the formation of the groove also provides space for the second mounting plate 12.

[0056] Refer again Figure 2 The cover structure 1 also includes a shield 13, and there are two shields 13. The two shields 13 are arranged on both sides of the groove along the length direction of the first mounting plate 11, and are arranged in close contact with the first mounting plate 11. The side of the second mounting plate 12 facing away from the first mounting plate 11 is lower than the side of the shield 13 facing away from the first mounting plate 11, so as to form a mounting groove between the two shields 13, and the baffle 2 is installed in the mounting groove, and the side of the baffle 2 facing away from the first mounting plate 11 is flush with the side of the shield 13 facing away from the first mounting plate 11.

[0057] It can be understood that the second mounting plate 12 is located in the groove of the first mounting plate 11, and a mounting groove that can accommodate the baffle 2 is formed between the second mounting plate 12 and the two baffles 13. In this way, the baffle 2 can be located in the mounting groove after being installed to the second mounting plate 12, and a hidden design of the baffle 2 can be realized. The side of the baffle 2 facing away from the first mounting plate 11 is flush with the side of the baffle 13 facing away from the first mounting plate 11, thereby avoiding the baffle 2 protruding from the baffle 13 and affecting the aesthetics of the audio.

[0058] Of course, in other embodiments, the side of the baffle 2 facing away from the first mounting plate 11 may also be lower than the side of the shield 13 facing away from the first mounting plate 11, that is, the baffle 2 may be completely located in the mounting groove to achieve a completely hidden design.

[0059] In addition, the sound outlet channel 102 and the baffle 13 are in different directions, so that the setting of the baffle 13 can avoid affecting the sound outlet channel 102, so that the cover structure 1 as a whole can be used as a cover for the speaker, which facilitates the assembly of the cover structure 1 and the speaker shell 4.

[0060] For example, referring to Figure 3 The length direction of the first mounting plate 11 is as follows: Figure 3 The X direction in the width direction is as follows Figure 3 In addition, the first direction is as follows Figure 3 In the Z direction, the length direction and the width direction of the first mounting plate 11 are perpendicular to the first direction in pairs.

[0061] It should be noted that the shield 13, the first mounting plate 11, and the second mounting plate 12 are integrally formed, for example, by injection molding. Of course, the shield 13, the first mounting plate 11, and the second mounting plate 12 can also be separately provided and assembled to form the cover structure 1, and the support ribs 3 can be integrally formed with the first mounting plate 11 or the second mounting plate 12. Alternatively, the first mounting plate 11, the second mounting plate 12, and the support ribs 3 can be integrally formed, while the shield 13 is formed separately. Alternatively, the shield 13 and the first mounting plate 11 can be integrally formed, and the second mounting plate 12 can be formed separately, and the support ribs 3 can be integrally formed with the first mounting plate 11 or the second mounting plate 12. This embodiment does not limit this.

[0062] In some embodiments, reference Figure 5 and Figure 6 In the length direction of the sound outlet channel 102, the outer edge of the first mounting plate 11 is flush with the outer edge of the second mounting plate 12; the inner end of the support rib 3 is flush with the wall surface of the through hole 101, and the outer end of the support rib 3 is located on the inner side of the outer edge of the first mounting plate 11.

[0063] It can be understood that the inner edge of the above-mentioned first mounting plate 11 constitutes the hole wall surface of the through hole 101, the inner edge of the second mounting plate 12 constitutes the hole wall surface of the through hole 101, the outer side surface of the first mounting plate 11 and the outer edge of the second mounting plate 12 are flush, and in the length direction of the support rib 3 from the inside to the outside, the inner end surface of the support rib 3 is flush with the hole wall surface of the through hole 101, and the outer end surface of the support rib 3 is located on the inner side of the outer edge of the first mounting plate 11 and also on the inner side of the outer edge of the second mounting plate 12.

[0064] That is to say, in this case, the sound output channel 102 is divided into two parts, which are defined as the first sound output channel and the second sound output channel from the inside to the outside, wherein the first sound output channel is connected to the through hole 101, and the second sound output channel is relatively far away from the through hole 101, and the support rib 3 is located in the first sound output channel. In this way, the connection between the first mounting plate 11 and the second mounting plate 12 can be achieved through the support rib 3, thereby improving the structural strength and avoiding the support rib 3 occupying the entire sound output channel 102 to separate the sound output channel 102 into a narrow and long channel, which is easy to generate airflow sound when the vibrator 6 moves.

[0065] Alternatively, in other embodiments, the outer end of the support rib 3 may be flush with the outer edge of the first mounting plate 11 and / or the outer edge of the second mounting plate 12, while the inner end of the support rib 3 is located outside the wall surface of the through hole 101. In this case, the sound output channel 102 is divided into two parts, defined as a first sound output channel and a second sound output channel from the inside out, wherein the first sound output channel is connected to the through hole 101, the second sound output channel is relatively remote from the through hole 101, and the support rib 3 is located within the second sound output channel 102. Alternatively, the inner end of the support rib 3 may be located outside the wall surface of the through hole 101, and the inner end of the support rib 3 is located inside the outer edge of the first mounting plate 11. In this case, the sound output channel 102 is divided into two parts, defined as a first sound output channel and a second sound output channel from the inside out, wherein the first sound output channel is connected to the through hole 101, the second sound output channel is relatively remote from the through hole 101, and a portion of the support rib 3 is located within the first sound output channel, while the other portion is located within the second sound output channel.

[0066] It should be noted that the outer edges of the first mounting plate 11 and the second mounting plate 12 are not flush. When the outer edge of the first mounting plate 11 is closer to the through-hole 101 than the outer edge of the second mounting plate 12, the outer ends of the support ribs 3 are flush with the outer edge of the first mounting plate 11 or located inside the outer edge of the first mounting plate 11. When the outer edge of the second mounting plate 12 is closer to the through-hole 101 than the outer edge of the first mounting plate 11, the outer ends of the support ribs 3 are flush with the outer edge of the second mounting plate 12 or located inside the outer edge of the second mounting plate 12.

[0067] In some embodiments, a plurality of support ribs 3 are provided in each sound outlet channel 102 . The plurality of support ribs 3 are sequentially arranged along the circumference of the through hole 101 , and a gap exists between two adjacent support ribs 3 .

[0068] It is understandable that due to the arrangement of the support ribs 3, even if multiple support ribs 3 are arranged in the sound outlet channel 102, no narrow and long channels will be formed between two adjacent support ribs 3, which can avoid obvious airflow sound and reduce wind noise.

[0069] In some embodiments, the vibrator 6 is a woofer. Therefore, the distance between the first mounting plate 11 and the second mounting plate 12 must meet the woofer's travel range, preventing the woofer from contacting the first mounting plate 11 or the baffle 2 during operation. The distance between the first mounting plate 11 and the second mounting plate 12 is selected based on the woofer and is not specifically limited herein.

[0070] In some embodiments, the baffle 2 is a transparent baffle.

[0071] As can be understood, the use of a transparent baffle allows the user to see the vibrator 6 through the baffle 2, making the vibrator 6 visible and satisfying the user's visual needs. Moreover, when the vibrator 6 is selected as a woofer, the movement of the vibrator 6 can be observed through the baffle 2 when the vibrator 6 is working, which can increase the user's sensory enjoyment.

[0072] It should be noted that the baffle 2 can be mounted on the second mounting plate 12 by bonding, clamping, and screw fixing, which is not specifically limited here.

[0073] like Figures 7 to 10 As shown, an embodiment of the present application further provides a speaker, including the cover assembly of the above-mentioned speaker.

[0074] In some embodiments, reference Figure 7 The above-mentioned speaker is a bar-shaped speaker. The cover structure 1 extends entirely along the length of the first mounting plate 11. In this case, the housing 4 can be a rectangular housing 4 with a length along the length of the first mounting plate 11. The cover structure 1 and the housing 4 are connected to form a mounting cavity for the speaker. Alternatively, the above-mentioned speaker can be of other shapes, which are not specifically limited here.

[0075] In some embodiments, the speaker further includes a vibrator 6 , which is connected to the first mounting plate 11 and faces the through hole 101 .

[0076] The speaker further includes a housing 4, the cover structure 1 is connected to the housing 4, and the sound outlet channels 102 are located in the cavity of the housing 4. The housing 4 is provided with a first sound outlet hole 41 corresponding to each sound outlet channel 102. The vibrator 6 is located in the cavity.

[0077] It is understandable that since the sound outlet channel 102 is located in the cavity of the shell 4, it is necessary to open a first sound outlet hole 41 on the shell 4 corresponding to each sound outlet channel 102 so that the sound emitted by the vibrator 6 is transmitted through the sound outlet channel 102 and the first sound outlet hole 41 and diffuses outward.

[0078] It should be noted that the extension direction of the first sound hole 41 can be the same as or different from the extension direction of the sound outlet channel 102. If the extension direction of the first sound hole 41 is different from the extension direction of the sound outlet channel 102, the first sound hole 41 will guide the propagation of sound again.

[0079] For example, in a specific implementation, two sound outlet channels 102 are formed between the first mounting plate 11 and the second mounting plate 12 of the cover structure 1 of the cover assembly, so that the shell 4 is provided with a first sound outlet hole 41 corresponding to the two sound outlet channels 102 .

[0080] In some embodiments, reference Figure 9 A plurality of first reinforcing ribs 411 are provided in the first sound hole 41 , and the plurality of first reinforcing ribs 411 are arranged at intervals along the length direction of the first sound hole 41 . In the length direction of the first sound hole 41 , any first reinforcing rib 411 is staggered with the supporting rib 3 .

[0081] Understandably, if no reinforcing ribs are provided in the first sound outlet hole 41, a weak area will be formed in the shell 4 at the first sound outlet hole 41. When the shell 4 is squeezed or impacted, the shell 4 will be broken at the first sound outlet hole 41. Therefore, the provision of the first reinforcing rib 411 can enhance the structural strength of the shell 4 at the first sound outlet hole 41, and the first reinforcing rib 411 and the supporting rib 3 are staggered, which can not only reduce the impact of the airflow generated by the movement of the vibrator 6, but also make the flow of the airflow have a certain irregularity to avoid wind noise. In addition, the cooperation of multiple first reinforcing ribs 411 and the supporting ribs 3 in the sound outlet channel 102 can play a role in blocking foreign matter, that is, preventing foreign matter from entering the sound outlet channel 102 through the first sound outlet hole 41, and also preventing foreign matter from entering the through hole 101 on the cover structure 1 through the first sound outlet hole 41 and the sound outlet channel 102 to damage the vibrator 6.

[0082] In addition, when a plurality of supporting ribs 3 are provided in the sound outlet channel 102 , any first reinforcing rib 411 and the plurality of supporting ribs 3 are staggered.

[0083] In some embodiments, a second reinforcing rib 412 is further disposed in the first sound outlet 41 . The second reinforcing rib 412 extends along the length direction of the first sound outlet 41 and is connected to the plurality of first reinforcing ribs 411 .

[0084] It can be understood that by providing the first reinforcing rib 411, the structural strength of the shell 4 at the first sound outlet 41 can be further enhanced, and the first reinforcing rib 411 and the multiple second reinforcing ribs 412 cooperate to form a grille, which can block foreign matter and prevent foreign matter from entering the sound outlet channel 102 through the first sound outlet 41.

[0085] It should be noted that the first reinforcing rib 411 and the second reinforcing rib 412 are integrally formed with the shell 4 , for example, the shell 4 , the first reinforcing rib 411 and the second reinforcing rib 412 are integrally injection molded, which can improve the overall structural strength of the shell 4 .

[0086] In some embodiments, reference Figure 8 and 10 The speaker further includes a decorative grille 5 connected to the housing 4 and located outside the housing 4 cavity. A second sound hole 51 is formed on the decorative grille 5 corresponding to the first sound hole 41. A plurality of third reinforcing ribs 511 are disposed within the second sound hole 51. The plurality of third reinforcing ribs 511 are spaced apart along the length of the second sound hole 51. Any third reinforcing rib 511 is staggered with respect to the support rib 3 along the length of the second sound hole 51.

[0087] Understandably, if no reinforcing ribs are provided within the second sound outlet 51, a weak area will be formed in the decorative mesh 5 at the second sound outlet 51. When the decorative mesh 5 is squeezed or impacted, the decorative mesh 5 will break at the second sound outlet 51. Therefore, the provision of the third reinforcing ribs 511 can enhance the structural strength of the decorative mesh 5 at the second sound outlet 51. Furthermore, the cooperation between the multiple third reinforcing ribs 511 and the supporting ribs 3 within the sound outlet channel 102 can block foreign matter, preventing it from entering the sound outlet channel 102 through the second sound outlet 51. Furthermore, the staggered arrangement of the third reinforcing ribs 511 and the supporting ribs 3 can reduce the impact of the airflow generated by the movement of the vibrator 6, creating a certain degree of irregularity in the airflow and thus preventing wind noise.

[0088] It should be noted that, at this time, no reinforcing ribs may be provided in the first sound outlet hole 41 on the shell 4, but a third reinforcing rib 511 may be provided in the second sound outlet hole 51 of the decorative mesh cover 5. The third reinforcing rib 511 can prevent foreign matter from entering the first sound outlet hole 41 and the sound outlet channel 102.

[0089] Exemplarily, a plurality of first sound holes 41 are provided on the shell 4, some of which are provided with first reinforcing ribs 411, while other first sound holes 41 serve to connect the sound outlet channel 102 and the second sound outlet hole 51. In this case, the first reinforcing ribs 411 may not be provided in these first sound holes 41.

[0090] In a specific implementation, the shell 4 is provided with two opposite first sound holes 41 in the width direction of the first mounting plate 11, wherein a first reinforcing rib 411 and a second reinforcing rib 412 are provided in one of the first sound holes 41, and no reinforcing rib is provided in the other first sound hole 41, and the first sound hole 41 corresponds to the second sound hole 51 on the decorative mesh cover 5.

[0091] In addition, when a plurality of supporting ribs 3 are provided in the sound outlet channel 102 , any third reinforcing rib 511 is staggered with the plurality of supporting ribs 3 .
