Description

Technical Field

[0001] This utility model relates to a speaker box, and more particularly to a speaker box with an independent sound output structure. Background Technology

[0002] The horn located at the head of the driver's cab is often concealed, installed in a dedicated horn box with several strips of grille on the front and top surfaces. The disadvantages of this design are: 1. Rainwater can enter the box from the top, with some water accumulating in the corners. Over time, rust will develop at the joints, and the rust will seep out, affecting the appearance; 2. Because the box is part of the driver's cab ceiling, the vibration and noise from the horn are very noticeable; 3. This structure does not meet the requirements of Chilean users, namely, that the horn must be protected from rain, snow, hail, and other external substances. Utility Model Content

[0006] According to another embodiment of the present invention, the mounting beam is further comprising a U-shaped structure.

[0007] According to another embodiment of the present invention, the connecting hole is further provided with a cover, the cover having a concave structure, including a large round end and a small round end, a sealing strip being provided at the connection of the small round end, and a sound outlet being provided at the large round end.

[0008] According to another embodiment of the present invention, the sound outlet is further included by welding or gluing to the large circular end of the cover.

[0009] According to another embodiment of the present invention, the sound outlet is further provided with an elongated hole.

[0010] According to another embodiment of the present invention, the top cover is further provided with a handle and is fixed to the upper end of the box body by bolts.

[0011] The beneficial effects of this utility model are: by dividing the speaker box into a speaker installation area and an independent sound output area, this solves the problem that users require the speaker to be protected from the influence of external substances such as rain, snow, and hail, while also preventing water accumulation and reducing vibration noise in the driver's cab.

[0014] Figure 2 This is a structural schematic diagram of the right view of this utility model;

[0015] The components are: 1. Top cover, 2. Box body, 3. Mounting bolts, 4. Sealing strip, 5. Cover, 6. Sound outlet. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.

[0017] This type of speaker enclosure with an independent sound output structure consists of components such as the enclosure body, cover, sound outlet, shell, sealing strip, mounting beam, mounting bolts, and mounting nuts.

[0018] like Figure 1-2 As shown in the figure, the box 2 has a detachable top cover 1 at the top, a fixing mechanism for connecting the speaker is provided on the inside of the box 2, and a connection hole for the speaker sound output part is provided on the box 2.

[0019] The fixing mechanism includes a protruding block fixed to the inside of the housing 2, a mounting beam connected to the protruding block by mounting bolts 3, and one end of the horn connected to the mounting beam by mounting nuts 8.

[0020] The mounting beam has a U-shaped structure, which allows it to connect to the protruding block and also to mount the speaker on the mounting beam.

[0021] A cover 5 is provided inside the connecting hole. The cover 5 has a concave structure and includes a large round end and a small round end. A sealing strip 4 is provided at the connection of the small round end, and a sound outlet 6 is provided at the large round end. The function of the cover 5 is to fix the horn mouth at the front end of the horn. During installation, the mounting end of the horn that is connected to the mounting beam passes through the cover 5, the horn mouth end is fixed to the cover 5, and the mounting end is fixed to the mounting beam.

[0022] The sound outlet 6 is welded or glued to the large round end of the cover 5, and the sound outlet 6 has a long strip-shaped hole.

[0023] The top cover 1 is equipped with a handle and is fixed to the upper end of the housing 2 by bolts. The handle makes it easy to open the top cover 1.

[0024] The enclosure, sound outlet, and sealing strip form an independent sound output area. The enclosure and sound outlet are welded together before being welded to the cabinet. Note that the lowest point of the sound outlet is hollowed out to facilitate rainwater drainage. The cabinet, top cover, mounting beam, mounting bolts, and mounting nuts form the speaker mounting area. The mounting beam is a movable beam. The cabinet includes a corresponding fixed beam. The speaker installation sequence is as follows: place the speaker mouth into the independent sound output area, install the speaker onto the mounting beam, connect the mounting beam to the fixed beam of the cabinet, insert the sealing strip at the junction of the speaker and the enclosure, and the speaker installation and area division are completed at this step. Finally, the top cover is closed.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
