Description

Technical Field

[0001] The utility model relates to a loudspeaker installation structure for automobile instruments. Background Art

[0002] To enhance driving comfort, ensure safety, and satisfy passenger entertainment needs, speakers are often installed in the dashboard area of ​​a car. These speakers not only provide high-quality audio output to enhance the music playback experience, but also play important navigation instructions and safety warnings, thereby improving the overall driving experience. However, when designing and installing these speakers, the available space in the dashboard area of ​​some small and compact cars is very limited, leaving no room for the speakers and their wiring. Utility Model Content

[0003] The utility model provides a speaker installation structure which has a small volume and can reduce the installation space of the speaker.

[0004] The speaker mounting structure includes an instrument housing, a PCB board installed on the front side of the housing, and a speaker embedded in the rear side of the housing. The housing protrudes toward the PCB board to form a cavity for placing the speaker wires. The cavity is provided with a window for the wire connector to pass through and connect with the PCB board.

[0005] Preferably, a groove for bending the wire is reserved on one side of the speaker where the wire exits.

[0006] Preferably, the shell is provided with a circle of enclosure around the edge of the speaker.

[0007] Preferably, a limiting column is provided on the inner side of the enclosure relative to the edge of the speaker.

[0008] Preferably, the speaker is detachably embedded in the rear side of the housing by screws.

[0009] The speaker mounting structure described above can facilitate the assembly and disassembly of the speaker by installing the speaker externally on the rear side of the shell and installing the speaker internally on the rear side of the shell in an overlapping mounting structure. At the same time, the cavity of the shell protruding toward the PCB board can hide and protect the wires, so that there is space for storing the wires connecting the speaker and the PCB board and the connectors plugged into the PCB board, which not only realizes the storage of the wires and connectors, but also reduces the speaker installation space.

[0017] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0019] If there are descriptions involving "first" or "second" in the embodiments of the present invention, the descriptions of "first" or "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" can explicitly or implicitly include at least one of such features. In addition, the technical features of each embodiment can be arbitrarily combined. In order to make the description concise, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0020] like Figure 1-7As shown, a speaker mounting structure includes an instrument housing 1, a PCB board 2 mounted on the front side of the housing, and a speaker 3 embedded in the rear side of the housing. The housing protrudes toward the PCB board (printed circuit board) to form a cavity 5 for accommodating the speaker's wires 4. The cavity is provided with a window 7 for a connector 6 for the wires to pass through and plug into the PCB board. By creating an overlapping mounting structure with the speaker externally mounted on the rear side of the housing and the speaker embedded in the rear side of the housing, the speaker can be easily assembled and disassembled. The cavity protruding from the housing toward the PCB board conceals and protects the wires, providing space for the wires connecting the speaker to the PCB board. This not only allows for wire storage but also reduces the speaker installation space.

[0021] A groove 8 for bending the wire is left on one side of the speaker where the wire exits, thereby preventing the wire from being squeezed.

[0022] The shell is provided with a circle of enclosure 9 around the edge of the speaker, which can reduce the obvious protrusion of the speaker, make the appearance look smoother, and also play a certain waterproof role.

[0023] A limiting column 10 is provided on the inner side of the enclosure relative to the edge of the speaker. The speaker is embedded in the shell based on the limiting column to facilitate fitting with the installation surface of the shell.

[0024] The speaker is detachably embedded in the rear side of the housing by means of screws 11, making it easy to disassemble and assemble the speaker.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
