Description

Technical Field

[0001] This utility model relates to the field of modular speaker technology, and in particular to a modular speaker for dubbing. Background Technology

[0002] A speaker is a device that converts electrical signals into sound signals. Its core function is to amplify and reproduce audio. Through acoustic design, it optimizes sound quality. Speakers used for dubbing are professional audio equipment, mainly used to accurately monitor sound details to ensure dubbing quality. They achieve high-fidelity sound reproduction through professional-grade loudspeakers and acoustic design, accurately presenting the true timbre of human voices, background music, and sound effects, avoiding distortion. At the same time, they have strong resolution of high, mid, and low frequency sounds, which can highlight subtle flaws such as inaccurate pronunciation and noise, making it convenient to adjust dubbing details and emotional expression in a timely manner.

[0003] Because the control box and speaker of the existing modular speaker system are not integrated, when people use the modular speaker system for dubbing, the separately placed control box and speaker will appear messy. When people move around the speaker, they may accidentally touch the speaker, causing it to tip over or move, which will affect the overall stability of the modular speaker system during use and reduce the overall efficiency when the control box and speaker are used together.

[0004] Therefore, it is necessary to provide a new combination speaker for dubbing to solve the above-mentioned technical problems. Utility Model Content

[0022] In the specific implementation process, such as Figures 1-4As shown, a combination speaker for dubbing includes a combination box 4, a control box 401 placed inside the combination box 4, a speaker body 402, and an electric actuator 2 located on top of the combination box 4. The characteristic feature is that a buffer assembly is provided between the electric actuator 2 and the combination box 4 to cushion the combination box 4. The buffer assembly includes a spring plate 3, a hexagonal bolt 301, a rubber pad 302, a first spring 303, a connecting plate 304, a second spring 305, and a limiting plate 306. The hexagonal bolt 301 is located on the upper end of the spring plate 3. The spring plate 3, the connecting plate 304, and the limiting plate 306 are all threadedly connected to the hexagonal bolt 301. The lower end of the spring plate 3 is fixed... A rubber pad 302 is fixedly connected to the upper end of the connecting plate 304, and the outer side of the connecting plate 304 and the rubber pad 302 are fixedly connected. A rubber pad 302 is fixedly connected to the upper end of the limiting plate 306. A first spring 303 is provided between the rubber pad 302 at the bottom of the spring plate 3 and the rubber pad 302 embedded in the connecting plate 304. A second spring 305 is provided between the bottom of the rubber pad 302 embedded in the connecting plate 304 and the rubber pad 302 at the upper end of the limiting plate 306. Both the first spring 303 and the second spring 305 are provided on the outer side of the hexagonal bolt 301. A first partition 406 and a second partition 405 are provided inside the combination box 4. The two partitions 407, 406, and 407 are fixedly connected to the left and right inner walls of the combination box 4 at both ends. A control box 401 is located at the center of the first partition 406. A speaker body 402 is located at the bottom of the combination box 4 and at the center of the second partition 407. A fixing horizontal plate 403 is provided on the upper surface of the control box 401 and the two speaker bodies 402. The fixing horizontal plate 403 is attached to the bottom of the first partition 406, the second partition 407, and the separation box on both sides, and is fixedly connected to both ends by screws 404. Multiple holes for sound transmission are opened on one surface of the combination box 4, and each hexagonal bolt 301 is used. Rubber pad 302, first spring 303, and second spring 305 are grouped together, and there are four groups in total, all of which are square and set at the four vertices. The connecting plate 304 is U-shaped, and both ends of the connecting plate 304 are fixedly connected to the combination box 4. The limiting plate 306 is located inside the connecting plate 304. The bottom of the electric push rod 2 is fixedly connected to the fixing plate 1, and the top of the electric push rod 2 is fixedly connected to the spring plate 3. There are four electric push rods in total. The fixing plate 1 has four holes. The center of the upper back side of the combination box has a cable collection port 405. The center of the inner side of the first partition 406 and the second partition 407 both have cable distribution ports 408.

[0023] The working principle of this utility model is as follows: The device is fixed to the ceiling via holes in the fixing plate 1. When using this device, the combination box 4 is pushed out using the electric push rod 2. When the combination box 4 vibrates due to sound conduction, the connecting plate 304 is fixedly connected to the combination box 4, causing resonance between them. At this time, a small portion of the vibration is absorbed by the rubber pad 302 embedded in the connecting plate 304, while the first spring 303 and the second spring 305 at the upper and lower ends of the rubber pad 302 absorb most of the vibration. The vibration may cause displacement of the connecting plate 304, but the four hexagonal bolts 301 act as a limiting force. To prevent displacement, the limiting plate 306 is fixedly connected to the rubber pad 302 on the upper surface of the limiting plate 306, which limits the possibility of the rubber pad 302 detaching and avoids the risk of the combination box 4 falling. The combination box 4 is provided with a hub port 405 and a branch port 408. The hub port 405 is used as the main bus line, and the branch port 408 is used for the electrical connection between the control box 401 and the speaker body 402. When the speaker is finished, it is retracted by the electric push rod (2). The fixed cross plate 403 is attached to the upper surface of the control box 401 and the two speakers to make the speakers more stable and avoid misalignment due to their own vibration.

[0024] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
