Description

Technical Field

[0001] This utility model relates to the field of speakers, and in particular to a speaker connection and hanging device. Background Technology

[0002] Large speakers are generally used in large commercial venues or school playgrounds and other relatively open spaces. However, the sound effect of a single large speaker is not good when placed in the venue, which affects the music playback effect of the entire venue. Therefore, multiple speakers or combinations of multiple speakers are often needed to hang them up to make them work better, so that the sound played by the speakers can cover the entire venue and achieve better effect.

[0003] Currently, existing multi-speaker systems are typically connected via pins, which makes disassembly difficult during replacement or repair. Furthermore, the lack of axial restraint on the pins can cause unwanted noise due to excessive vibrations from the pins or speakers during operation. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a speaker connection and hanging device. This utility model is achieved through the following technical solution:

[0005] An audio connection and hanging device includes several housings and at least one hanging bracket. Each housing contains components for audio sound generation. One end of each housing has a connecting plate, and the other end has a snap-fit ​​plate. A sliding plate is slidably mounted on the snap-fit ​​plate, allowing it to move up and down. Each of the two sides of the sliding plate has a fixed protrusion. Hooks are rotatably mounted on both sides of the sliding plate, each hook including a snap-fit ​​groove and a contact surface. The contact surface contacts the protrusion to transmit power from the sliding plate to the hook. Two first connecting posts are fixedly mounted on the connecting plate, their positions corresponding to the snap-fit ​​grooves. Two second connecting posts are mounted on the hanging bracket.

[0006] In the above technical solution: the outer shell is used to house audio-related components and other components of the hanging device; the bracket is used to fix it to the wall or other structures and to achieve a fixed connection between the outer shell and the wall; the connecting plate is used to house the first connecting post; the snap-fit ​​plate is used to house components such as hooks; the sliding plate is used to control the posture of the hooks; the hooks change the position of the snap-fit ​​groove by rotating, thereby achieving snap-fit ​​or separation with the first connecting post; the protrusion and the contact surface cooperate to convert the up-and-down movement of the sliding plate into the rotation of the hooks.

[0007] A further feature of this invention is that an eccentric wheel is rotatably mounted on the snap-fit ​​plate, a placement groove is provided in the middle of the sliding plate, the eccentric wheel is disposed in the placement groove, and the eccentric wheel simultaneously maintains contact with two opposite sides of the placement groove.

[0008] In the above technical solution: the eccentric wheel is used together with the sliding plate to form a crank-slider mechanism, thereby realizing the up-and-down reciprocating motion of the sliding plate.

[0009] A further feature of this invention is that: one end of the outer shell is provided with a first mounting groove, and the other end is provided with a second mounting groove; the connecting plate is disposed in the first mounting groove, and the snap-fit ​​plate is disposed in the second mounting groove; and the sum of the thickness of the connecting plate and the thickness of the hook is the same as the thickness of the second mounting groove.

[0010] In the above technical solution: the setting of the first mounting groove and the second mounting groove ensures that the connecting plate and the snap-fit ​​plate are both located inside the outer shell, thus avoiding structural damage; the sum of the thickness of the second mounting groove and the thickness of the hook is the same as the thickness of the second mounting groove, so that when the hook is snapped into the first connecting post, the hook will not wobble, thereby avoiding excessive vibration and noise.

[0011] A further feature of this invention is that a circular groove is provided on the outer shell, and a knob is rotatably disposed in the groove. The knob passes through the outer shell and is fixedly connected to the eccentric wheel.

[0012] In the above technical solution: the groove is used to set the knob; the knob is used to drive the internal eccentric wheel to rotate on the outside of the housing.

[0013] This utility model discloses a speaker connection and hanging device, which, compared with the prior art:

[0014] 1. This utility model, through the arrangement of hook, sliding plate, eccentric wheel and knob, enables the hook to be separated from or engaged with the first connecting post by rotating the knob, thereby simply realizing the engagement between two adjacent speakers;

[0015] 2. This utility model makes the connection between the hook and the first connecting post more secure and reduces shaking. At the same time, the relevant setting of the hook thickness also prevents the hook from shaking in the direction of the first connecting post, thereby avoiding noise caused by excessive vibration of the hook.
