Description

Technical Field

[0001] This utility model relates to the field of speakers, specifically to a horn speaker in which the rear of the horn is fixed to the back panel of the speaker enclosure. Background Technology

[0002] Horn speakers are widely used in Hi-Fi, stage, and conference room settings. Currently, integrated horn speakers (where the horn and speaker unit share the same cabinet) primarily use the horn to handle mid-to-high frequency playback. There are two main methods for connecting and fixing the horn to the cabinet: one is to use screws to fix the horn opening to the front panel of the cabinet; the other is to use a screw hole (bolt) structure protruding from the outer wall of the horn in the center to fix it to the front panel of the cabinet. Method one restricts the horn opening from being larger than the cabinet, while method two increases the manufacturing cost of the horn, requires manual tightening of bolts inside the cabinet, and has a smaller fixing surface, making it unsuitable for fixing large horns and increasing the difficulty of the fixing operation.

[0003] In addition, there are horn speakers that use a base to be independently fixed on top of the cabinet, but these are not considered integrated horn speakers and are also more expensive to manufacture.

[0004] For integrated horn speakers, if the horn opening is larger than the cabinet's horizontal diameter, it accentuates the horn's appearance and is aesthetically pleasing. However, the first type of horn fixing mentioned above is not suitable because the horn opening needs to be smaller than the cabinet's horizontal diameter. The second type of horn fixing is problematic because it's difficult to reach inside the cabinet to tighten the bolts, and the protruding screw holes (bolts) on the horn's outer wall are unsightly and may even affect the horn's sound quality. Furthermore, the manufacturing cost of horns is high. For large horns, this is neither a reliable nor ideal fixing method. Therefore, improving and optimizing the connection and fixing structure between the large horn and the cabinet is a very practical design and innovation. Summary of the Invention

[0005] To improve and optimize the connection and fixing structure between the horn and the cabinet, especially to facilitate the installation and connection of horns larger than the cabinet's horizontal diameter without significantly increasing costs, this utility model proposes a horn speaker with the rear of the horn fixed to the back panel of the cabinet.

[0006] The technical solution of this utility model is implemented as follows:

[0007] The present invention relates to a horn speaker with the rear part of the horn fixed to the back panel of the cabinet, comprising a cabinet and a horn. The horn is characterized in that: the rear part of the horn is provided with a connecting structure, which enters the cabinet through the horn support hole on the front panel of the cabinet along with the rear part of the horn, and the rear part of the horn is fixed to the back panel of the cabinet through the fixed connection of the connecting structure with the back panel of the cabinet.

[0008] To ensure a secure fixation of the rear of the horn, the connecting structure includes an outward-facing plate fixedly connected to the rear plate of the horn and fasteners connected to the outward-facing plate. The outward-facing plate is larger than the rear plate, and the outward-facing plate is fixedly connected to the back panel of the housing via fasteners, thereby fixing the rear of the horn to the back panel of the housing.

[0009] To accommodate the installation and fixing of horns of different sizes and weights, and to ensure the stable and reliable use of the connection structure, the connection structure also includes a connecting plate, which is connected to the fasteners and located between the outer plate and the back plate of the housing.

[0010] To ensure the stable and reliable installation of the outer panel, a hollow positioning column is provided between the connecting plate and the outer panel.

[0011] To facilitate the installation and fixing of the outer display panel to the rear plate of the horn, a locking slot is provided on the outer display panel.

[0012] To accommodate the installation and fixing of horns of different sizes and weights, the fasteners can adopt a variety of different structural forms. The fasteners can be composed of a fastening bolt and a long nut connected to the fastening bolt, with the long nut located on the inside of the back panel of the housing and connected and fixed to a rear bolt that passes through the connection hole on the back panel of the housing; or the fasteners can be fastening bolts, with the rear end of the fastening bolt connected and fixed to the connection hole on the back panel of the housing.

[0013] To ensure a secure installation, 3 to 10 fasteners are provided.

[0014] To ensure reliable installation of the large horn, several horn pads are fixed at the edge of the horn support holes on the front panel of the housing. Furthermore, 3 to 10 horn pads are provided.

[0015] To facilitate the installation of different numbers of fasteners, the outer plate and connecting plate can be circular, polygonal, or other geometric shapes.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This utility model employs a connecting structure at the rear of the horn. During installation, this connecting structure extends into the cabinet along with the rear of the horn and is fixedly connected to the back panel of the cabinet, thereby fixing the rear of the horn to the back panel of the cabinet. This fixing method is not only simple in structure and easy to set up, but also effectively improves the convenience and stability of horn installation and fixing. In particular, horns larger than the horizontal diameter of the cabinet can be easily installed and fixed to the cabinet without increasing the cost too much. The large horn speaker highlights the image of the horn, which is also a manifestation of beauty.

[0018] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0027] Example 1:

[0028] like Figure 1 and Figure 2As shown, a horn drive head 8 is installed at the rear end of the horn 2, and an outer extension plate 31 is fixed to the front of the rear plate 21 of the horn 2. The size of the outer extension plate 31 is larger than that of the rear plate 21. In this embodiment, the outer extension plate 31 is square, so it protrudes beyond the rear plate 21 in both length and width, providing sufficient space for the fastening bolts 33 to be installed and extended rearward. The outer extension plate 31 is installed by first inserting it laterally into the rear part of the horn 2 through an approximately U-shaped notch 311, and then fixing it to the rear plate 21 of the horn 2 using multiple bolts and nuts. A through hole is provided at each of the four corners (or near the edge) of the outer extension plate 31, and the threaded section of the fastening bolt 33 passes through the through hole and extends rearward to connect with a connecting plate 32. To ensure the connecting plate 32 effectively stabilizes the fastening bolts 33, a hollow positioning post 34 is fixed on the surface of the connecting plate 32 facing the outer plate 31, corresponding to the position of each fastening bolt 33. The central hole of each hollow positioning post 34 penetrates the connecting plate 32. The threaded section of each fastening bolt 33 passes through the through hole of the outer plate 31 and then extends rearward along the central hole of the hollow positioning post 34 to the outside of the connecting plate 32, where it is threadedly connected and fixed to the front of the long nut 35 on the outer side of the connecting plate 32. This ensures that the other end of each hollow positioning post 34 abuts against the outer plate 31, thus ensuring both the reliable installation of the connection structure 3 formed by the outer plate 31, connecting plate 32, fastening bolts 33, and long nuts 35, and the stable connection of the fastening bolts 33. A connecting hole 121 is provided on the back plate 12 of the box body at the position corresponding to each long nut 35. The threaded section of the rear bolt 4 is inserted into the box body 1 from the outside to the inside through the connecting hole 121 and is threadedly connected and fixed to the rear part of the long nut 35, thereby fixing the rear part of the horn 2 to the back plate 12 of the box body.

[0029] The outer plate 31 and the connecting plate 32 can also be circular, polygonal or other geometric shapes, and the number of fastening bolts 33 should preferably be 3 to 10.

[0030] Example 2:

[0031] like Figure 3 As shown, this embodiment omits the connecting plate 32 based on embodiment one. In this case, the connecting structure 3 is formed by the outer plate 31, the fastening bolt 33, and the long nut 35. The threaded section of the fastening bolt 33 passes through the through hole on the outer plate 31 and is threadedly connected to the front end of the long nut 35 for fixation. The threaded section of the rear bolt 4 is inserted into the housing 1 from the outside to the inside through the connecting hole 121 on the back plate 12 of the housing and is threadedly connected to the rear end of the long nut 35 for fixation, thereby fixing the rear part of the horn 2 to the back plate 12 of the housing. This connecting structure 3 is used to fix the horn 2 when the weight of the horn 2 is not large, or when the fastening bolt 33 does not need to be too long.

[0032] Of course, if the horn 2 is not heavy or the fastening bolt 33 does not need to be too long, a hollow positioning post can be fixed on the rear side of the outer plate 31. The threaded section of the fastening bolt 33 passes through the through hole on the outer plate 3 and then passes through the center hole of the hollow positioning post to be threadedly connected and fixed to the connecting hole 121 on the back plate 12 of the box. Thus, the rear part of the horn 2 can be fixed on the back plate 12 of the box without the need for the long nut 35 and the rear bolt 4.

[0033] Example 3:

[0034] like Figure 4 and Figure 5 As shown, this embodiment is based on embodiment one. Several horn pads 5 are fixed to the edge of the horn support hole 111 on the front panel 11 of the housing using screws. Each horn pad 5 is configured as a frustum-shaped structure with a larger bottom and a smaller top, and is inclined towards the center of the horn support hole 111. Specifically, grooves corresponding to the number and position of the horn pads 5 are formed at the edge of the horn support hole 111. The bottom surface of each groove is a slope, and the bottom surface of the horn pad 5 is connected to the slope of the groove, as shown. Figure 4 As shown. This structure is used to fix larger horns with greater weight, that is, horn pads 5 are used to support and fix the horn 2 at the horn support hole 111. The number of horn pads 5 depends on the weight of the horn 2, preferably 3 to 10, and they are arranged at equal intervals around the axis of the horn support hole 111 to ensure the stability of the support.

[0035] Example 4:

[0036] like Figure 6 As shown, this embodiment is based on the connection structure and fixing method of Embodiment 1, and the outer extension plate 31 is fixed to the rear end plate 21 of the horn 2.

[0037] like Figure 7 As shown, in this embodiment, the opening of the horn 2 is larger than the transverse diameter of the enclosure 1 and protrudes outside the enclosure 1. A tweeter 6 is provided above the horn 2, and a woofer 7 is provided below it. Mounting holes for fixing the tweeter 6 and the woofer 7 are respectively provided on the upper and lower parts of the enclosure 1.

[0038] One method for installing the horn 2 described in this utility model is as follows: First, insert a long guide screw into the connecting hole 121, screw the guide screw into the rear of the long nut 35, and the rear of the horn 2 enters the housing 1 through the horn support hole 111 via the guide screw. Then, screw out the guide screw and insert the rear bolt 4 and tighten it on the rear of the long nut 35, thereby fixing the horn 2 as a whole onto the back plate 12 of the housing.

[0039] like Figure 8 The image shown is a physical reference diagram of the connection structure according to Embodiment 1 of this utility model.

[0040] This utility model has been described through embodiments, but it does not constitute a limitation on this utility model. Other variations of the disclosed embodiments, which are readily apparent to those skilled in the art, should fall within the scope of the claims of this utility model, with reference to the description of this utility model.
