Description

Technical Field

[0001] This utility model relates to the field of audio equipment manufacturing, specifically a subwoofer. Background Technology

[0002] A subwoofer, also known as a subwoofer speaker, is an audio device specifically designed to enhance the low-frequency range (below 100Hz) of audio. It produces long-wavelength low-frequency sounds that ordinary speakers cannot effectively emit due to size limitations. By amplifying the bass band, a subwoofer adds depth and power to audio, and even some infrasound frequencies that are inaudible to humans can still be felt to create a powerful and impactful effect.

[0003] While existing subwoofers are usable, their diaphragms are easily damaged by external factors and cannot prevent foreign objects from entering, resulting in a lifespan that does not meet expectations. Utility Model Content

[0004] To achieve the above objectives, the purpose of this utility model is to provide a subwoofer that can improve the directivity of the speaker enclosure and the sound pressure level of the coverage area, overcome resonance to a greater extent, and effectively reduce resonance intensity, thereby solving the problems existing in the background art. This utility model provides the following technical solution:

[0005] A subwoofer includes a grille and a cabinet. The grille is rectangular and installed in front of the driver head. The grille has evenly distributed mesh holes in the middle. The cabinet has a cuboid structure and an embedded box is installed on the back panel of the cabinet. The grille at the front can prevent the diaphragm from being damaged by the outside and can also block foreign objects from entering the subwoofer, thereby extending its service life. The embedded box at the back facilitates the integration of internal circuitry. The subwoofer has a simple and practical appearance and can be used in a wide range of scenarios.

[0006] As a further embodiment of this utility model: the cross-section of the box body perpendicular to its center line is rectangular.

[0007] As a further embodiment of this utility model, the dimensions of the box are 759mm*504mm*532mm.

[0008] As a further embodiment of this utility model, the material of the housing is aluminum alloy.

[0009] As a further embodiment of this utility model, the size of the mesh cover is 497mm*497mm*2mm.

[0010] As a further embodiment of this utility model: screw holes are provided on the edges of both the mesh cover and the embedded box, and both the mesh cover and the embedded box are installed on the box body by screws.

[0011] As a further aspect of this utility model: the side of the box is printed with the ESD logo.

[0012] As a further embodiment of this utility model, the housing is manufactured by molding, lathe cutting, 3D printing or stamping.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The grille of this product is located in front of the driver head, which can prevent the diaphragm from being damaged by the outside and can block foreign objects from entering the subwoofer, thereby extending its service life; there is an embedded box on the back for easy integration of internal circuitry. The appearance is simple and practical, and it can be used in a wide range of scenarios. Attached Figure Description

[0019] In the diagram: 100 - mesh cover; 200 - box body. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] See Figures 1-4 A subwoofer includes a grille 100, a cabinet 200, and an embedded box; the cabinet 200 has a rectangular structure, the grille 100 is installed in front of the driver head, the side of the cabinet 200 is printed with the ESD logo, and the back panel of the cabinet 200 is designed with an embedded box.

[0023] Preferably, the mesh cover 100 is rectangular with evenly distributed mesh holes in the middle.

[0024] Specifically, such as Figure 2As shown, the mesh cover 100 is a standard rectangle with a circular mesh hole in the center. This design reduces the entry of foreign objects.

[0025] As a preferred embodiment, the dimensions of the housing 200 are 759mm*504mm*532mm.

[0026] In this embodiment, the housing 200 has a large volume, making it suitable for use in cinemas.

[0027] Preferably, the housing 200 is made of aluminum alloy.

[0028] In this embodiment, aluminum alloy is used as the material for the enclosure 200, which can reduce the resonance caused by sound wave vibration during subwoofer operation, and is also corrosion resistant and has a long service life.

[0029] Preferably, the edge of the embedded box is provided with screw holes, and the embedded box is installed on the housing 100 by screws.

[0030] In this embodiment, the embedded box is installed on the back of the enclosure 200. This design is aesthetically pleasing when wiring, and the embedded design is also less prone to scratches.

[0031] It should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "fixed," "set," etc., should be interpreted broadly. For example, they can refer to welded connections, bolted connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
