[0002] Music has been an indispensable part of human life since ancient times, serving multiple functions such as soothing the mind, cultivating temperament, and relieving stress. Audio equipment is a crucial medium for music transmission. With the rapid development of various sound technologies and the continuous improvement of people's living standards, more and more people are paying attention to enhancing their aesthetic and artistic cultivation and spiritual qualities, and music is an important aspect of this. Music is composed of syllables of different frequencies; high frequencies express the soaring power of sound, while low frequencies embody its depth. Therefore, the ability to perfectly reproduce both high and low frequency syllables in sound is extremely important in audio equipment.

[0003] Modern audio equipment with bass effects typically features a passive radiator, which reproduces bass through its response. Currently, the industry commonly places the passive radiator at the rear or side of the audio structure. This is the prevalent rear-mounted and side-mounted audio structure seen in the market today. However, with a rear-mounted radiator, the effect is only visible from behind the speaker; with a side-mounted radiator, the sound dynamics are only visible from the side. Therefore, existing audio structures do not allow for a direct visual experience of the sound dynamics from the front, resulting in visual inconvenience. Utility Model Content

Detailed Implementation

[0034] The above-mentioned objectives of this utility model and its structural and functional characteristics will be described with reference to the preferred embodiments shown in the accompanying drawings.

[0035] Please see Figures 1 to 9 As shown, this utility model provides an audio structure 1, including: a rear shell 10, a speaker 11, a tweeter panel 12, a bridge 13, a panel 14, a back plate 15, a first silicone ring 16, a second silicone ring 17, a mesh frame 18, and a mesh body 19.

[0036] The rear housing 10 has an opening 100, a side wall 101 surrounding the opening 100, and a rear wall 102 connected to the side wall 101. The rear wall 102 and the side wall 101 together form a groove 103, which communicates with the opening 100. The speaker 11 is disposed within the groove 103 of the rear housing 10 and close to the rear wall 102. The tweeter panel 12 is disposed within the groove 103 of the rear housing 10 and close to the speaker 11, and the tweeter panel 12 is located between the speaker 11 and the opening 100. The tweeter panel 12 is provided with a tweeter 121. The cable tray 13 is disposed within the groove 103 of the rear housing 10 and is located between the tweeter panel 12 and the opening 100. The panel 14 is disposed on the opening 100 of the rear shell 10 and is fixed to the side wall 101 surrounding the opening 100. The panel 14 has a front opening 140, a side annular wall 141 surrounding the front opening 140, and a rear side wall 142 connected to the side annular wall 141. The rear side wall 142 has a through opening 1420 corresponding to the opening 100. The rear side wall 142 and the side annular wall 141 together form an accommodating space 143. The through opening 1420 connects the accommodating space 143 and the groove 103. The backing plate 15 is disposed in the front opening 140 of the panel 14. The first silicone ring 16 is disposed in the accommodating space 143 of the panel 14 and located between the backing plate 15 and the rear side wall 142. The first silicone ring 16 has a first opening 160 corresponding to the through opening 1420. The second silicone ring 17 is disposed within the receiving space 143 of the panel 14 and located between the back plate 15 and the cable tray 13. The second silicone ring 17 has a second opening 170 corresponding to the through-hole 1420, wherein the second silicone ring 17 is located within the first opening 160 of the first silicone ring 16, and the inner diameter of the first silicone ring 16 is larger than the outer diameter of the second silicone ring 17. The mesh frame 18 is disposed at the front opening 140 of the panel 14 and connected to the back plate 15. The mesh frame 18 has a frame opening 180 corresponding to the through-hole 1420, and the frame opening 180 is disposed corresponding to the back plate 15. The mesh body 19 is disposed on the mesh frame 18 and covers the frame opening 180 and the back plate 15 below it. In this embodiment, the speaker 11 is a woofer, and a tweeter 121 is provided in the tweeter panel 12 on the speaker 11. Through the combination of the tweeter 121 of the tweeter panel 12 and the woofer of the speaker 11, the sound structure 1 can achieve a better sound effect.

[0037] Furthermore, in this embodiment, a bracket 20 is provided connected to the rear shell 10. More specifically, the bracket 20 is connected to the side wall 101. Since the cross-sectional area of ​​the opening 100 is larger than the cross-sectional area of ​​the rear wall 102, the rear shell 10 has a shape that is wider at the front and narrower at the back. This makes the side wall 101 gradually narrower from the opening 100 towards the rear wall 102. Therefore, by placing the bracket 20 near the middle of the side wall 101 and between the side wall 101 and the rear wall 102, the bracket 20 can be made invisible from the front of the speaker structure 1. In other words, the design of this utility model can present a visual effect of hiding the bracket 20 from the front of the speaker structure 1, giving people a simple and elegant visual experience.

[0038] In this embodiment, a transformer 21, a band switch assembly 22 and a frequency divider 23 are also installed in the groove 103 of the rear shell 10. The transformer 21, the band switch assembly 22 and the frequency divider 23 are adjacent to the bottom of the groove 103 and are located between the rear wall 102 and the speaker 11. In addition, the mesh frame 18 has a frame edge 181 surrounding the frame opening 180 and a recessed groove 182 formed on the frame edge 181. The bottom of the recessed groove 182 has the frame opening 180. The mesh body 19 can be embedded in the recessed groove 182 to cover the frame opening 180 located at the bottom of the recessed groove 182. This can effectively protect the back plate 15 located in the front opening 140 of the panel 14, the first silicone ring 16 and the second silicone ring 17 in the accommodating space 143, and the transformer 21, band switch assembly 22 and frequency divider 23 in the groove 103, so as to avoid external contamination.

[0039] It is worth mentioning that, such as Figure 3As shown, since the mesh frame 18 protrudes from the front opening 140 of the panel 14, the mesh body 19 is located outside the panel 14. The mesh frame 18 is connected to the back plate 15. When the speaker 11 vibrates to push the airflow and generate sound waves, the airflow enters the receiving space 143 of the panel 14 along the tweeter panel 12 and exerts a thrust on the back plate 15 located in the front opening 140 of the panel 14. This causes the back plate 15, which is pushed by the airflow, to move forward, thereby causing the mesh frame 18 and mesh body 19 on the back plate 15 to also move forward, resulting in a noticeable protrusion from the front opening 140 of the panel 14. When the airflow thrust applied to the back plate 15 disappears, the back plate 15 is pulled back by the elastic force of the first silicone ring 16 and the second silicone ring 17 located in the receiving space 143, causing the back plate 15 to move backward and return to its original position. The backrest plate 15 undergoes forward and backward displacement due to the thrust of airflow and the elastic pull of the first silicone ring 16 and the second silicone ring 17, thereby creating a visually dynamic sonic effect. Therefore, this invention directly places the backrest plate 15 on the front or front of the speaker structure 1, and provides the mesh frame 18 and mesh body 19 on it to protect the backrest plate 15 and other related components below it, such as the first silicone ring 16, the second silicone ring 17, the tweeter panel 12, and the speaker 11. When the backrest plate 15 is displaced forward and backward by the airflow caused by the sound waves emitted by the speaker 11, the mesh frame 18 and the mesh body 19 also move and displace simultaneously with the backrest plate 15. This allows the forward and backward displacement of the mesh frame 18 and mesh body 19 to be directly visible from the front of the speaker structure 1, creating a visually dynamic sonic effect.

[0040] It is understood that in this embodiment, the mesh frame 18 is disposed on the top surface 154 of the back plate 15, and the back plate 15 and the mesh frame 18 are fixedly connected by adhesive, thus ensuring that there is no sound resonance problem between the two. However, it is not limited to this. The back plate 15 can also be designed to be located in the frame opening 180 of the mesh frame 18, and the back plate 15 can be glued and fixed to the mesh frame 18. Since the back plate 15 has a plate perforation 150, which corresponds to the through opening 1420, the mesh body 19 provided on the mesh frame 18 can cover the plate perforation 150 of the back plate 15, thus effectively protecting the first silicone ring 16 and the second silicone ring 17 located in the accommodating space 143 from external contamination. In this embodiment, the mesh 19 is an aluminum mesh, and the perforation 150 of the plate is an elliptical perforation or an elliptical perforation, but it is not limited to this, and the perforation 150 of the plate can also be designed as other types of holes.

[0041] Please see Figures 5 to 7As shown, the bottom surface 155 of the back plate 15 is provided with a first plate portion 151, a second plate portion 152, and a plurality of ribs 153. The plate through-hole 150 penetrates the top surface 154 and the bottom surface 155 of the back plate 15. The ribs 153 are used to reinforce the structure of the back plate 15. The first plate portion 151 is used to house the first silicone ring 16, and the second plate portion 152 is used to house the second silicone ring 17. In addition, the first plate portion 151 is provided with a plurality of first protrusions 1511, which are used to engage and position the plurality of first top recesses 1611 of the first silicone ring 16. The second plate portion 152 is provided with a plurality of second protrusions 1521, which are used to engage and position the plurality of second top recesses 1711 of the second silicone ring 17. It is understandable that the first protrusion 1511, the second protrusion 1521, and the rib 153 can be integrally formed into a straight strip. This not only facilitates design and manufacturing but also helps in the assembly and positioning of the first silicone ring 16 and the second silicone ring 17. However, it is not limited to this; they can also be positioned by adhesive bonding.

[0042] Please see Figure 8 As shown, the rear sidewall 142 of the panel 14 is also provided with a wall-mounted portion 1421, which is used for mounting the first silicone ring 16. Multiple plate protrusions 1422 may be provided on the wall-mounted portion 1421, which are used to engage and position the multiple first bottom recesses 1621 of the first silicone ring 16. Figure 9 As shown, the cable tray 13 has a mounting opening 130, a frame portion 131 surrounding the mounting opening 130, and a mounting portion 132 formed on the frame portion 131. The mounting portion 132 is used for mounting the second silicone ring 17, and the mounting portion 132 has a plurality of mounting protrusions 1321 for engaging and positioning the second silicone ring 17 with a plurality of second bottom recesses 1721. However, it is not limited to this, it can also be positioned by adhesive bonding. In addition, the frame portion 131 extends inward toward the mounting opening 130 with a plurality of locking portions 133 for locking and fixing the frame portion 131 to the tweeter panel 12.

[0043] Specifically, such as Figures 5 to 9As shown, the back plate 15 has a first plate portion 151, the rear sidewall 142 of the panel 14 has a wall portion 1421, and the first silicone ring 16 includes a first ring plate portion 161, a first ring wall portion 162, and a first elastic portion 163 connecting the first ring plate portion 161 and the first ring wall portion 162. The first ring plate portion 161 is disposed on the first plate portion 151, and the first ring wall portion 162 is disposed on the wall portion 1421. The first top recesses 1611 are provided on the first ring plate portion 161 to engage with the first protrusions 1511 positioned on the first plate portion 151, and the first bottom recesses 1621 are provided on the first ring wall portion 162 to engage with the plate protrusions 1422 positioned on the wall portion 1421 on the rear sidewall 142. Furthermore, the back plate 15 has a second plate portion 152, the cable tray 13 has a mounting portion 132, and the second silicone ring 17 includes a second ring plate portion 171, a second ring wall portion 172, and a second elastic portion 173 connecting the second ring plate portion 171 and the second ring wall portion 172. The second ring plate portion 171 is disposed on the second plate portion 152, and the second ring wall portion 172 is disposed on the mounting portion 132. The second top recesses 1711 are provided on the second ring plate portion 171 to engage with and be positioned on the second protrusions 1521 on the second plate portion 152, and the second bottom recesses 1721 are provided on the second ring wall portion 172 to engage with and be positioned on the mounting portion 1321 of the mounting portion 132 on the frame portion 131. It is understood that the above-mentioned engagement and positioning can also be achieved through adhesive bonding.

[0044] It is worth mentioning that, such as Figure 3 and Figures 6 to 7 As shown, the first silicone ring 16 and the second silicone ring 17 have approximately the same height and thickness, but the inner diameter of the first silicone ring 16 is larger than the outer diameter of the second silicone ring 17, so that the second silicone ring 17 can be located within the first opening 160 of the first silicone ring 16. Since the first silicone ring 16 and the second silicone ring 17 have approximately the same height and thickness, they can provide a more uniform elasticity to the back plate 15, making the vibration of the back plate 15 caused by airflow displacement more uniform and stable. This forms a smooth vibration to regulate low-frequency radiated sound waves, enhancing sound quality and dynamism, thereby achieving a better sound effect and dynamics.

[0045] Furthermore, both the first elastic portion 163 of the first silicone ring 16 and the second elastic portion 173 of the second silicone ring 17 are annular arc-shaped surfaces with a cross-section approximately semi-circular. The annular arc-shaped surface of the first elastic portion 163 includes an inner convex surface 1631 and an outer concave surface 1632, and the annular arc-shaped surface of the second elastic portion 173 includes an outer convex surface 1731 and an inner concave surface 1732. The inner convex surface 1631 of the first elastic portion 163 is positioned opposite the outer convex surface 1731 of the second elastic portion 173. This makes the spatial arrangement between the first silicone ring 16 and the second silicone ring 17 more compact, which is beneficial for reducing the size of the panel 14 and also for applying a stable and uniform elastic force to the back plate 15, making the back plate 15 more stable when it is displaced and vibrates due to airflow.

[0046] It is understood that the first silicone ring 16 can be made of other materials, and similarly, the second silicone ring 17 can also be made of other materials. In other words, this utility model does not limit the material of the elastic ring to silicone; other elastic materials can also be used. Furthermore, in this embodiment, the first silicone ring 16 and the second silicone ring 17 are two independent components, but this is not a limitation. The first silicone ring 16 and the second silicone ring 17 can also be integrated into a single interconnected component. In other words, this utility model does not limit the implementation of the first silicone ring 16 and the second silicone ring 17. It only needs to design an elastic unit and set it in the receiving space 143 of the panel 14 to provide space for the elastic movement of the back plate 15. The elastic unit can be further subdivided into a first elastic ring and a second elastic ring (i.e., the first silicone ring 16 and the second silicone ring 17) to connect the outer ring portion and the inner ring portion (i.e., the first plate portion 151 and the second plate portion 152) of the back plate 15 respectively, thereby achieving a better effect of uniform distribution of acoustic airflow thrust.

[0047] It is worth mentioning that the wire frame 18 and the wire mesh 19 can be integrated into a single wire frame unit, which is disposed in the front opening 140 of the panel 14 and connected to the backing plate 15. In other words, the wire frame unit can be configured by first directly attaching the wire mesh 19 to the wire frame 18, and then placing the wire frame 18 on the backing plate 15. Therefore, this utility model does not limit the wire mesh 19 to being detachably mounted on the wire frame 18; it can also be that the wire mesh 19 is pre-set on the wire frame 18, and then the wire frame 18 is placed on the backing plate 15. Alternatively, the wire frame 18 and the wire mesh 19 can be integrally formed, so when the wire frame unit is disposed in the front opening 140 of the panel 14 and connected to the backing plate 15, the wire frame 18 and the wire mesh 19 can be simultaneously disposed on the backing plate 15.

[0048] In summary, this utility model allows this speaker structure to be installed directly in front of a wall. Because it features a concealed bracket, the wiring is concealed within the wall and bracket, resulting in a clean and elegant visual effect. Furthermore, mounting the bracket on the wall provides a significantly superior front-facing sound effect compared to current rear-mounted and side-mounted speakers. Since there are currently no comparable products with a front-mounted speaker, this utility model's design of placing the speaker at the front is highly competitive in the market and offers substantial economic benefits.

[0049] Furthermore, the combined structure of the back panel used in this utility model can extend and increase the space within a limited space to optimize the sound effect and generate a visual dynamic impact. Moreover, two silicone rings are designed and installed on the back panel, so that the vibration can be more stable when the sound effect is generated to adjust the low frequency radiation sound waves to enhance the sound quality and dynamism, and achieve the effect of the sound effect being directly visible from the front of the speaker.

[0050] The present invention has been described in detail above. However, the above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made based on the present invention should still fall within the patent coverage of the present invention.
