Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a bamboo audio shell and an audio. Background Art

[0002] Among the existing audio products, most of their shells are made of plastic. The manufacturing cost of plastic shells is high, and they pollute the environment after use and are difficult to recycle. In addition, the raw materials of plastics mainly come from non-renewable resources such as petroleum and natural gas, and a large amount of energy chemicals are consumed in the production process. Therefore, it is of great practical significance to develop audio shell materials with lower development costs and more environmentally friendly. The Chinese patent with publication number CN216291319U discloses a bamboo Bluetooth speaker, whose bottom shell and cover are both made of bamboo. However, the bottom shell and cover are made of simple bamboo materials, which have poor strength and sound absorption effects, and durability cannot be guaranteed. In addition, wind noise is easily generated inside the speaker, which affects the sound effect. Therefore, the utility model aims to further develop and obtain a bamboo audio shell and a speaker to better meet actual needs. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0022] Example 1

[0023] refer to Figure 1 and Figure 2 As shown, the bamboo sound housing includes a shell, such as Figure 1 As shown, the shell is fixedly installed by a top plate 1, a bottom plate 2 and a side plate 3, and the shell has an open inner cavity. The top plate 1, the bottom plate 2 and the side plate 3 of the shell are all bamboo composite boards. In other preferred embodiments, the shell can also be installed by the bamboo composite board into other shapes such as oval, circular, or even special-shaped structures. These conventional changes are of course also within the protection scope of the present utility model.

[0024] like Figure 2 As shown, the bamboo composite board includes a substrate layer 5, a waterproof layer 6 and a sound-absorbing layer 7. The waterproof layer 6 is coated on the entire surface of the substrate layer to further improve the waterproof and anti-corrosion effect of the shell and further improve the durability. The sound-absorbing layer 7 is fixed on the substrate layer or embedded in the inner side of the substrate layer 5, so as to further absorb the noise inside the inner cavity of the shell and reduce the noise. In some preferred embodiments, the substrate layer 5 is preferably a carbonized bamboo layer, which has better strength performance. In other preferred embodiments, as an improvement, the substrate layer 5 is a carbonized bamboo layer made of bamboo filaments after dipping and high-pressure bonding, so that natural bamboo can be fully utilized. Bamboo itself is a good acoustic material, which has a good isolation ability for air and structural vibrations, can improve the sound effect to a certain extent, and can further improve its insect-proof effect through carbonization treatment after dipping, and has better strength and durability. And by setting the asphalt waterproof layer 6, its waterproof and insect-proof effect can be further improved. Through the combination of asphalt waterproof layer 6 and sound-absorbing cotton design, the asphalt waterproof layer 6 can handle low-frequency noise to a certain extent, while the sound-absorbing cotton is suitable for handling high-frequency noise. The combination has a more ideal noise handling effect.

[0025] As an improvement to the present embodiment, a mounting groove 13 is provided on the inner side of the substrate layer 5 , and the sound-absorbing cotton is laid flat and fixed in the mounting groove 13 by gluing or other methods.

[0026] Example 2

[0027] like Figure 3 The outer side of the substrate layer 5 of the bamboo speaker housing shown is configured to be an arc-shaped convex shape, thereby further increasing the strength while providing a more beautiful arc surface, resisting falling without deformation, and having better practicality.

[0028] Example 3

[0029] like Figure 4The bamboo speaker housing shown, as a further improvement of the present invention, has a decorative layer 12, which is a carbonized bamboo layer formed by high-pressure bonding of bamboo strips after being dipped in glue. Thus, the decorative layer 12 has a certain strength and the natural texture of the bamboo material itself, which can better meet the preferences of consumers who advocate nature.

[0030] As an improvement to this embodiment, the substrate layer 5 includes a first substrate layer 8 and a second substrate layer 9, a grid-type card slot is arranged on the surface of the first substrate layer 8, a matching convex track is arranged on the surface of the second substrate layer 9, and the first base layer and the second base layer are bonded by gluing. This design can further increase the deformation resistance, and further improved on this basis, a reinforcing layer 10 is arranged between the first substrate layer 8 and the second substrate layer 9, and the reinforcing layer 10 is preferably a glass fiber mesh, so as to further enhance the internal strength of the substrate, so that the whole has better pressure resistance and reduces damage during transportation and use.

[0031] In some preferred embodiments, sound-absorbing holes 11 may be provided on the substrate layer, especially on the inner second substrate layer 9, so as to further enhance the noise absorption effect while not affecting the overall strength.
