Description

Technical Field

[0001] This utility model relates to the field of speaker connection technology, and more specifically, to a vertical array speaker connection bracket. Background Art

[0002] A speaker is a device that converts electrical signals back into sound signals, and the fidelity of sound reproduction is an important criterion for evaluating speaker performance. An active speaker is an audio system with a built-in power amplifier (i.e., amplifier), integrating the power amplifier and speaker system into one unit. It can be directly paired with common audio sources (such as portable music players, CD players, DVD players, VCRs, etc.) to form a complete audio system. When speakers need to be used at a high position, they are typically raised directly using speaker stands or wall-mounted to a wall or building exterior.

[0003] In some special situations, multiple speakers can be arranged and connected vertically in a linear fashion using a dedicated hoisting bracket. For example, patent CN210351497U discloses a linear sound source array speaker. In the structure of multiple speakers connected vertically, the front ends of two adjacent speakers are connected by hinges, and the rear ends are supported by connecting strips. The connecting strips have multiple positioning grooves, and the outer wall of the speaker body has multiple through holes. According to the required tilt angle between adjacent speakers, the corresponding positioning grooves and positioning holes are selected and connected by clips. In this connection structure, since the connection and angle adjustment of the upper and lower speakers require manual assistance to lift the speaker and then adjust the position of the clip insertion holes, this method is time-consuming, labor-intensive, and has low installation efficiency. Utility Model Content

[0004] To overcome at least one of the defects in the prior art, this utility model provides a vertical array speaker connection bracket, which can easily pre-install adjacent speakers at a set angle before the array speakers are hoisted. Pre-installation can be completed by one person without the assistance of others, saving labor and improving installation efficiency.

[0005] This utility model provides a vertical array speaker connection bracket: it includes a mounting base plate installed on the side wall of the speaker housing, a hanging rib plate perpendicular to the mounting base plate, a plurality of first hanging holes arranged in multiple rows and columns at the upper end of the hanging rib plate, a movable hanging plate detachably connected to the lower end of the hanging rib plate, a plurality of second hanging holes at the lower end of the movable hanging plate, and a vertically extending oblique through hole at the lower end of the hanging rib plate that is inclined away from the mounting base plate. The upper end of the movable hanging plate is movably connected in the oblique through hole. A limiting component is also provided on the hanging rib plate. When the upper end of the movable hanging plate slides to the bottom in the oblique through hole, the limiting component abuts against the outer side wall of the movable hanging plate.

[0006] Compared with the prior art, the vertical array speaker connecting bracket of this utility model has the following advantages:

[0007] This utility model's vertical array speaker connection bracket structure, when applied to vertical array speakers, allows for the pre-stabilization of multiple speakers stacked vertically. Each speaker's back panel is fitted with a connection bracket; specifically, a mounting base is horizontally installed on the speaker's back panel. The free end of the movable hanging plate of the upper connection bracket connects to the hanging rib of the lower connection bracket, and the connection is made via the first hanging hole at the desired phase position based on the speaker's tilt angle. After the connection between the stacked speaker back panels is complete, the uppermost connection bracket is lifted using appropriate lifting equipment. Under gravity, the upper ends of the movable hanging plates on the connection brackets on the backs of the lower speakers slide along the oblique through holes to the bottom until they are fixed in place, thus achieving pre-installation on the ground. Multiple speakers can be vertically connected in a single upward lift, and the angles between adjacent speakers can be pre-selected, making it very convenient. Furthermore, this structure eliminates the need for manual assistance in lifting multiple speakers during pre-installation; one person can complete the task, saving time and effort and increasing installation efficiency.

[0008] As an improvement, the mounting rib includes two parallel fixing plates with an installation channel between them. Each fixing plate has multiple symmetrical first mounting holes at one end and elongated through holes at the other end. The movable mounting plate is vertically oriented, and its end away from the second mounting hole is movably fitted into the installation channel. A connecting shaft is detachably inserted into any two symmetrical first mounting holes. In this improved structure, the mounting rib includes two vertically oriented fixing plates, each with first mounting holes and elongated through holes, effectively enhancing the strength of the mounting structure.

[0009] In a further improvement, the limiting component includes a positioning stop bar. Connecting holes are provided on both fixed plates at their ends furthest from the first mounting hole and outside the elongated through hole. The two ends of the positioning stop bar pass through the two connecting holes respectively. When the movable mounting plate is in operation, the positioning stop bar abuts against and limits its movement against the outer wall of the movable mounting plate. In this improved structure, the anti-rotation limiting of the movable mounting plate can be achieved with a simple positioning stop bar, resulting in a simple structure and convenient installation.

[0010] In a further improvement, the two fixing plates are fixed to the mounting base plate by welding. The mounting base plate has four positioning holes, and both ends of the two fixing plates on the side facing the mounting base plate have protruding positioning blocks. These positioning blocks are inserted into their corresponding positioning holes. In this improved structure, the positioning holes and positioning blocks allow for pre-positioning of the two fixing plates during welding to the mounting base plate, ensuring accurate welding and consequently guaranteeing the symmetry and accuracy of the first mounting holes on the two fixing plates.

[0011] Preferably, the connecting shaft and the positioning stop are ball-type pins. The ball-type pin structure is simple, easy to assemble and disassemble, and improves installation efficiency.

[0012] In a further improvement, the movable mounting plate has a mounting through hole at one end away from the second mounting hole, and a hand-tightening bolt is inserted through the elongated through hole of one of the fixed plates. The screw end of the hand-tightening bolt passes through the mounting hole until it exits through the elongated through hole of the other fixed plate, and a locking nut is fitted to the outer end of the hand-tightening bolt.

[0013] Other improvements and advantages of this invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and drawings. Attached Figure Description

[0020] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0021] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0022] In the embodiments of this application, unless otherwise expressly specified and limited, the first feature at the "upper end" or "lower end" of the second feature may be in direct contact with the first feature, or indirect contact between the first and second features through an intermediate medium.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figures 1-4 As shown in the figure, this application discloses a vertical array speaker connection bracket, including a mounting base plate 1 for connecting and fixing to the speaker shell. The mounting base plate 1 has a rectangular structure, and a hanging rib plate perpendicular to it is connected to the mounting base plate 1. The hanging rib plate extends along the length direction of the mounting base plate 1 and is located at the middle position in its width direction. Specifically, a plurality of first hanging holes 2 arranged in multiple rows and columns are provided at one end of the hanging rib plate, and a movable hanging plate 3 is detachably connected to the other end of the hanging rib plate. A plurality of second hanging holes are provided at one end of the movable hanging plate 3. Hole 4, an elongated through hole 5 extending along its length is provided at one end of the mounting rib away from each of the first mounting holes 2. The elongated through hole 5 gradually tilts away from the mounting base plate 1 along the extension direction away from the first mounting hole 2, that is, the elongated through hole 5 is an oblique through hole. The movable mounting plate 3 is connected in an adjustable position at one end away from the second mounting hole 4 in the elongated through hole 5. A limit component is also provided on the mounting rib. When the upper end of the movable mounting plate 3 slides to the bottom in the oblique through hole, the limit component abuts against the outer wall of the movable mounting plate 3 to limit it.

[0025] See appendix Figure 1 It can be seen that the connecting bracket of this structure is installed vertically, and a connecting bracket is installed on the upper and lower adjacent speaker back panels respectively. The free end of the movable hanging plate 3 on the upper connecting bracket is connected to the corresponding first mounting hole 2 on the lower connecting bracket. Specifically, according to the requirements of the speaker tilt angle, the first mounting hole 2 and the second mounting hole 4 at the corresponding positions are selected.

[0026] The oblique through-holes in the above structure are mainly for the pre-installation of the upper and lower speakers before hoisting. Specifically, during pre-installation, multiple speakers are stacked together vertically, and one installer can complete the pre-installation. Simply install connecting brackets on the back panel of each speaker, and then move the free end of the upper movable hanging plate 3 downward to connect to the first hanging hole 2 at the corresponding position on the lower hanging rib. In addition, the oblique through-holes allow the movable hanging plate 3 to move flexibly, which is convenient for pre-installation.

[0027] In the above structure, connecting through holes are provided at the four corners of the mounting base plate 1, and corresponding mounting holes are pre-set on the speaker housing. The mounting base plate 1 is fixed to the speaker housing by four screws. In this embodiment, the mounting rib includes two parallel fixing plates 6, with a mounting channel 7 between the two fixing plates 6. Multiple first mounting holes 2 are symmetrically provided at one end of each of the two fixing plates 6, and elongated through holes 5 are symmetrically provided at the other end of each of the two fixing plates 6. The movable mounting plate 3 is arranged vertically, and the end of the movable mounting plate 3 away from the second mounting hole 4 is movably fitted into the mounting channel 7. The limiting component is connected between the two fixing plates 6.

[0028] In this embodiment, a corresponding connecting shaft 8 is installed in any two symmetrical first mounting holes 2 between the two fixed plates 6. When the free end of the upper movable mounting plate 3 is connected to the lower mounting rib, the connection is limited by the connecting shaft 8. In this structure, preferably, the connecting shaft 8 is a conventional structure with a ball pin, which eliminates the need for processing. Moreover, the ball pin is easy to install and remove, and after installation, it is limited by the ball pin, preventing the connecting shaft 8 from detaching from the first mounting hole 2.

[0029] More specifically, the limiting component in the above structure includes a positioning stop 9. Both fixed plates 6 have connecting holes 10 at the ends away from the first mounting hole 2 and on the side of the elongated through hole 5 away from the installation point. The two ends of the positioning stop 9 are respectively inserted into the two connecting holes 10. When the movable hanging plate 3 is in the working state, the positioning stop 9 abuts against and limits the outer end face of the movable hanging plate 3 to ensure the stability of the movable hanging plate 3 at the bottom of the oblique through hole.

[0030] See appendix Figure 4In this embodiment, preferably, the two fixing plates 6 are fixed to the mounting base plate 1 by welding, which improves the accuracy of the connection position between the fixing plates 6 and the mounting base plate 11 and ensures that the first mounting holes 2 and the elongated through holes 5 on the two fixing plates are symmetrical. In this structure, four positioning holes 11 are provided on the mounting base plate 1, and positioning blocks 12 are provided on both ends of the lower side of the two fixing plates 6. The positioning blocks 12 on the lower end face of the two fixing plates 6 are respectively inserted into the corresponding positioning holes 11, so as to realize the pre-positioning of the welding position between the fixing plates 6 and the mounting base plate 1 and avoid the position changing during the welding process.

[0031] In this embodiment, the positioning stop 9 is preferably a ball pin. The ball pin is an existing conventional structure, which can be directly used to save processing. Moreover, the ball pin is easy to disassemble and assemble. After insertion, it is limited by the steel ball, so the pin will not come out of the connecting hole.

[0032] See appendix Figure 2 , 3 In embodiment 4, the movable mounting plate 3 has a mounting through hole at the end furthest from the second mounting hole 4. A hand-tightening bolt 13 passes through the elongated through hole 5 of one of the fixed plates 6. The screw end of the hand-tightening bolt 13 passes through the mounting hole and exits through the elongated through hole 5 of the other fixed plate 6. A locking nut 14 is fitted to the outer end of the hand-tightening bolt 13. In this structure, the hinge shaft is made of a hand-tightening bolt 13, which can be manually tightened to install and remove the movable mounting plate 3 in the elongated through hole 5, which is very convenient.

[0033] In some other implementations, the connection between the movable mounting plate 3 and the mounting rib plate can also be achieved through a structure of pins and radial pins.
