Description

Technical Field

[0001] This utility model relates to the field of audio component technology, and in particular to a passive radiator mounting structure and a smart speaker. Background Technology

[0002] A passive radiator cone, also known as a passive radiator, empty paper cone, passive radiator, or passive diaphragm, is a component similar to a speaker unit but without a voice coil and drive system. It typically consists of a frame, diaphragm, and suspension. The diaphragm extends radially towards the center, forming a cavity, which may contain a replaceable counterweight. The diaphragm's movement is driven by airflow within the enclosure. When the speaker unit operates and emits sound, the diaphragm moves, causing the air within the sealed enclosure to be compressed and expanded. This pressure change causes the passive radiator cone to vibrate, pushing the air outside the enclosure and thus producing sound.

[0003] In existing technologies, such as the carbon fiber composite passive radiator with good low-frequency performance disclosed in CN208657068U, the installation of the existing passive radiator cone mainly adopts adhesive installation, that is, the mounting holes are pre-set on the side wall of the speaker, and the passive radiator cone is fixed by adhesive such as glass glue. The assembly process is complicated and inefficient. When the speaker is used outdoors, the adhesive part is easily damaged by wind, rain and sun, which can cause the passive radiator cone to fall off.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0019] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] In existing technologies, such as the carbon fiber composite passive radiator with good low-frequency performance disclosed in CN208657068U, the installation of the existing passive radiator cone mainly adopts adhesive installation, that is, the mounting holes are pre-set on the side wall of the speaker, and the cone is fixed by adhesive similar to sealant. Since the adhesive is not easy to control, the assembly process is complicated and inefficient. When the speaker is used outdoors, the adhesive part is easily damaged by wind, rain and sun, which can cause the passive radiator cone to fall off.

[0023] Based on the aforementioned problems in the existing technology, this utility model provides a passive radiant basin installation structure, such as... Figure 1 and Figure 2 As shown, the passive radiant basin installation structure includes: a passive radiant basin 200; a housing 100, with a first clearance hole 111 provided on the wall panel 110 of the housing 100, and an assembly base 120 provided on one side of the wall panel 110, the assembly base 120 including at least two oppositely arranged sliding grooves 121; a limiting tray 300, the limiting tray 300 being detachably and pluggably disposed in the sliding grooves 121; the limiting tray 300 including a stepped slot 311 (e.g., Figure 3 The second clearance hole 310 (shown) and the stepped groove 311 interferometrically clamp the passive radiation basin 200 onto the wall plate 110 at the edge of the first clearance hole 111.

[0024] This utility model assembles the passive radiant cone 200 by providing an assembly base 120 with a sliding groove 121 on the wall panel 110 of the enclosure 100, and a limiting tray 300 detachably disposed in the assembly base 120. Compared with the adhesive structure, the limiting tray 300 has the advantages of tight interference fit, no influence from the external environment, and easy assembly and replacement. When applied to outdoor audio equipment, it can reduce the impact of the external environment on the product life and improve the sound quality.

[0025] In the above embodiments, the main body of the passive radiator installation structure of this utility model is a housing 100, which specifically refers to the shell structure of the speaker. The passive radiator 200 is installed on a wall panel 110 of the housing 100. Since the passive radiator 200 is an auxiliary sound-producing component of the speaker, the vibrating surface of the passive radiator 200 should be avoided during actual installation. Therefore, in this embodiment, a first clearance hole 111 is provided on the wall panel 110. The shape of the first clearance hole 111 is adapted to the outline shape of the passive radiator 200. The diameter of the first clearance hole 111 should be slightly smaller than the diameter of the passive radiator 200 to limit and prevent the passive radiator 200 from falling off.

[0026] Meanwhile, an assembly base 120 is provided on one side of the wall panel 110. Correspondingly, the passive radiant basin mounting structure also includes a limiting tray 300, which is used to fix the passive radiant basin 200. Specifically, the assembly base 120 includes at least two sliding grooves 121, which are arranged opposite to each other to limit the corresponding sides of the limiting tray 300. In addition, the limiting tray 300 is also provided with a second clearance hole 310 that matches the contour shape of the passive radiant basin 200. A stepped groove 311 (e.g., ...) is provided on one side of the second clearance hole 310 corresponding to the first clearance hole 111. Figure 3 As shown, the stepped slot 311 is used to accommodate the passive radiation basin 200, and the second clearance hole 310 is used to avoid the vibration surface on the other side of the passive radiation basin 200.

[0027] When the limiting tray 300 is inserted into the slide groove 121, the passive radiant basin 200 is pre-installed at the stepped groove 311 corresponding to the second clearance hole 310. When the limiting tray 300 is installed in the predetermined position in the assembly base 120, the second clearance hole 310 corresponds to the first clearance hole 111. The stepped groove 311 on the second clearance hole 310 forms a limit on the back side of the edge of the passive radiant basin 200, and the edge of the first clearance hole 111 limits the front side of the edge of the passive radiant basin 200. At the same time, under the limiting action of the two slide grooves 121, the passive radiant basin 200 is interference-fitted with the wall panel 110, thereby achieving the effect of installing and fixing the passive radiant basin 200.

[0028] In one possible embodiment of this utility model, such as Figure 2 and Figure 3 As shown, in order to facilitate users to carry and move the speaker outdoors, a handle 400 structure is also provided in this embodiment. The handle 400 can be made of materials such as rubber and plastic. The handle 400 structure cooperates with the passive radiant basin installation structure mentioned above, and can further fix the limiting tray 300.

[0029] Specifically, the handle 400 is located on the side of the wall panel 110 of the cabinet 100 away from the mounting base 120, that is, on the outside of the cabinet 100. The two ends of the handle 400 are fixedly connected to the wall panel 110 to fix the position of the handle 400. The center position of the handle 400 corresponds to the first clearance hole 111 mentioned above. Since the passive radiator 200 is located on the side of the mounting base 120 corresponding to the first clearance hole 111, and the shape of the passive radiator 200 is usually funnel-shaped or spherical, the first clearance hole 111 and the passive radiator 200 form clearance space on one side of the handle 400, which makes it easier for the user to grip the handle 400, and at the same time makes the overall structure of the speaker more compact and reasonable.

[0030] More specifically, such as Figure 1 and Figure 2 As shown, connection holes 112 are respectively provided on the wall panel 110 at the positions corresponding to both ends of the handle 400. These connection holes 112 correspond to the positions of the connecting seats 330 provided on the assembly base 120. In actual production, the handle 400 is fixedly connected to the box body 100 by bolts. Specifically, the two ends of the handle 400 are fixedly connected to the connecting seats 330 provided on the limiting tray 300 by bolts passing through the connection holes 112. On the one hand, the handle 400 is fixed, and on the other hand, the bolts fix the limiting tray 300 to the wall panel 110, restricting the sliding of the limiting tray 300 in the slide groove 121, and further enhancing the stability of the structure.

[0031] In practice, users can simply rotate the bolts to install or remove the handle 400 and the limit tray 300 simultaneously, which greatly simplifies the assembly process and improves the efficiency of maintenance and replacement of parts.

[0032] Furthermore, in one specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a flow guide 113 is also provided on the side of the wall panel 110 corresponding to the handle 400. The flow guide 113 is arranged around the edge of the first clearance hole 111. In actual installation, the cross-sectional shape of the flow guide 113 can be set to be inclined along a predetermined angle or a predetermined arc. Such an inclined design can effectively guide the flow of air or liquid and avoid the formation of a stagnant area around the first clearance hole 111, thereby reducing the damage to the passive radiant basin 200 caused by water or dust accumulation. In addition, the arrangement of the flow guide 113 also cooperates with the handle 400 to provide a larger clearance space and a rounded and gentle outer side of the box 100, so that the user can grip the handle 400 while avoiding discomfort caused by contact with the structure on the box 100.

[0033] To reduce the impact of sound waves generated by the passive radiator 200 being blocked by the handle 400, thus minimizing the effectiveness, such as... Figure 2 and Figure 3 As shown, in this embodiment, a clearance hole 410 is also provided at the center of the handle 400. The clearance hole 410 should be oval in shape and corresponds to the position of the passive radiating diaphragm 200. On the one hand, it provides clearance space for the amplification of sound waves, and on the other hand, it ensures the structural strength of the handle 400. In practical applications, the setting of the clearance hole 410 can reduce the obstruction of sound waves by the handle 400 during propagation, thereby ensuring that the sound emitted by the audio equipment is clearer and purer, and ensuring the sound performance of the audio equipment.

[0034] In another possible embodiment of this utility model, such as Figure 1 and Figure 2 As shown, in order to improve the connection strength between the bolts at both ends of the handle 400 and the limiting tray 300, the connecting seat 330 is preferably set to protrude from the limiting tray 300 in actual production. The protruding direction is towards the inside of the box 100. The advantage of this setting is that, on the one hand, the thickness of the connecting seat 330 can be increased to increase the structural strength and ensure the stability of the connection with the bolts. On the other hand, the thickness of the limiting tray 300 can be reduced so that the thickness of the corresponding mounting base 120 can be reduced, thereby providing more installation space inside the box 100.

[0035] Correspondingly, such as Figure 1 and Figure 2 As shown, the assembly base 120 also includes a limiting panel 122 integrally formed with the two slides 121. The edges of the limiting panel 122 are respectively set perpendicular to the two slides 121. The edges of the limiting panel 122 and the edges of the two slides 121 enclose each other to form a concave structure, so that the inserted limiting tray 300 forms a fitting assembly. In this embodiment, since the connecting seat 330 protrudes from the limiting tray 300, when the limiting tray 300 is inserted into the predetermined position in the assembly base 120, the connecting seat 330 corresponding to the side of the limiting panel 122 abuts against the side of the limiting panel 122, thereby restricting the installation position of the limiting tray 300 in the assembly base 120. This ensures the accuracy of the installation of the limiting tray 300 during the production process, so that the connecting hole 112 on the wall panel 110 naturally corresponds to the connecting seat 330 on the limiting tray 300. At the same time, in conjunction with the stepped slot 311 provided on the second clearance hole 310, the effect of accurately positioning the installation position of the passive radiant basin 200 can be achieved.

[0036] Furthermore, since during actual use of the audio equipment, factors such as impacts, vibrations, or installation pressure may cause stress concentration on the side of the limiting panel 122 due to the mounting base on the limiting tray 300, leading to deformation or even damage to the limiting panel 122, this embodiment also provides several connecting tenons 123 on the side of the limiting panel 122 facing the wall panel 110, such as... Figure 2 As shown, several connecting tenons 123 are spaced apart, and adjacent connecting tenons 123 are fixedly connected. The connecting tenons 123 fix the wall panel 110 to the limiting panel 122 and form a support structure similar to a skeleton. The end faces of the several connecting tenons 123 and the edge of the limiting panel 122 are located in the same horizontal plane. During the contact with the mounting base, they share the local stress. At the same time, the spaced connecting tenons 123 reduce the structural weight of this part and ensure the convenience of the speaker.

[0037] More specifically, in one embodiment of this utility model, in addition to using the bolts through the connecting hole 112 to assemble with the connecting seat 330 to lock the position of the limiting tray 300, as shown in the following... Figure 1 and Figure 2 As shown, in this embodiment, another locking structure is provided between the limiting tray 300 and the assembly base 120. That is, mounting posts 124 are respectively provided on the opposite sides of the two sliding grooves 121. The end of the mounting post 124 is provided with a mounting hole. Correspondingly, the limiting tray 300 is provided with an ear plate 320 corresponding to the position of the mounting post 124. The ear plate 320 is also provided with a through hole structure. During assembly, the bolts can be passed through the ear plate 320 and combined with the mounting hole to further firmly connect the limiting tray 300 and the assembly base 120. This double locking structure greatly enhances the stability of the limiting tray 300 in the assembly base 120, effectively preventing the limiting tray 300 from loosening or shifting due to vibration or external force, ensuring that the passive radiant cone 200 is always in the correct installation position, thereby ensuring the sound performance and service life of the audio equipment.

[0038] In addition, the ear plate 320 provides a gripping part for assemblers when installing the limiting tray 300, making it easy for users to quickly disassemble and reinstall when repairing or replacing parts, thus improving maintenance efficiency and ease of use.

[0039] In the above embodiment, the passive radiator 200, the first clearance hole 111, the mounting base 120, and the limiting tray 300 are all mirror-image arranged on two opposite wall panels 110 inside the enclosure 100. This symmetrical arrangement not only makes the overall structure of the audio equipment more balanced and stable, reducing the offset or shaking caused by unilateral vibration, but also effectively improves the sound production effect of the audio equipment. In practical applications, when the audio equipment plays music, the two oppositely arranged passive radiators 200 can work synchronously to form a more uniform and three-dimensional sound field, so that listeners can experience a more consistent and high-quality sound experience regardless of their location within the audio system.

[0040] Based on the above embodiments, the actual assembly process of the passive radiant basin mounting structure of this utility model is as follows: First, the passive radiant basin 200 is installed on the limiting tray 300 at the position of the stepped groove 311 corresponding to the second clearance hole 310. Then, the limiting tray 300 with the passive radiant basin 200 installed is aligned with the two slide grooves 121 on the assembly base 120, and the limiting tray 300 is smoothly inserted into the slide grooves 121 until the limiting tray 300 is installed in the predetermined position in the assembly base 120. This predetermined position is the abutment position between the connecting seat 330 and the limiting panel 122. At this time, the stepped groove 311 on the second clearance hole 310 forms a limit on the back side of the passive radiant basin 200, and the edge of the first clearance hole 111 limits the front side of the passive radiant basin 200. At the same time, under the limiting action of the two slide grooves 121, the passive radiant basin 200 and the wall panel 110 are interference-fitted.

[0041] Next, the handle 400 is installed by using bolts to pass through the connecting hole 112 on the wall panel 110 and fix it to the connecting seat 330 set on the limiting tray 300; and by using bolts to connect the ear plate 320 on the limiting tray 300 to the mounting column 124 located on one side of the slide groove 121, the assembly of the above passive radiant basin installation structure is realized.

[0042] Based on the above embodiments, this utility model also provides a smart speaker, which includes the passive radiator mounting structure described in the above embodiments. The passive radiator mounting structure includes: a passive radiator; a cabinet, with a first clearance hole on the wall panel of the cabinet and an assembly base on one side of the wall panel, the assembly base including at least two opposing sliding grooves; a limiting tray, which is detachably and pluggably disposed within the sliding grooves; the limiting tray includes a second clearance hole with a stepped groove, the stepped groove interfering with the passive radiator on the wall panel at the edge of the first clearance hole. This utility model, by providing an assembly base with sliding grooves on the wall panel of the cabinet and a limiting tray detachably disposed within the assembly base for assembling the passive radiator, offers advantages over adhesive structures. The limiting tray provides a tighter interfering fit, is unaffected by external environmental factors, and is easy to assemble and replace. When applied to outdoor audio equipment, it can reduce the impact of the external environment on product lifespan and improve sound quality.

[0043] In summary, this utility model provides a passive radiator mounting structure and a smart speaker. The passive radiator mounting structure includes: a passive radiator; a housing with a first clearance hole on its wall panel and an assembly base on one side of the wall panel, the assembly base including at least two opposing sliding grooves; and a limiting tray, which is detachably and pluggably disposed within the sliding grooves.
