Referring collectively to fig. 1-2, in accordance with an embodiment of the present application, an acoustic enclosure comprises: the casing 1, casing 1 include from outside to inside set gradually including planking 11 and inner panel 12, have the clearance between planking 11 and the inner panel 12 to form sound insulation chamber 13, seted up sound insulation hole 14 on the inner panel 12. The beneficial effects of the above technical scheme are: the sound insulation cavity 13 and the sound insulation hole 14 arranged on the shell 1 can effectively eliminate the noise of a sound source covered by the sound insulation cover, and can effectively play a role in water resistance.

Furthermore, the height of the waterproof board 4 is lower than that of the inner board 12, so that the material used in the manufacturing process is less, and the phenomenon that the sound insulation layer is wetted by water accumulated on the chassis can be prevented.

Further, the soundproof chambers 13 are partitioned into a plurality of soundproof areas 132 independent of each other by a plurality of partition plates 131; each sound insulation area 132 is a closed cavity formed by a partition plate 131, an inner plate 12 and an outer plate 11; at least one sound insulation hole 14 is formed in the inner plate 12 of each sound insulation area 132, so that noise emitted by the compressor can be effectively absorbed, noise of an air conditioner external unit can be effectively eliminated, and user experience is improved.

Further, the sound insulation cavity 13 is a helmholtz sound insulation cavity, which conforms to the sound insulation frequency of a helmholtz resonator, and according to the working principle of the helmholtz resonator, when the frequency of incident sound waves is close to the natural frequency of the resonator, the air column of the hole neck can vibrate, and in the vibration process, the sound energy is consumed due to the fact that the friction resistance is overcome, and finally the sound insulation effect is achieved. The formula for the damping frequency of an individual resonance chamber in a helmholtz resonator is as follows:

wherein: c: speed of sound; s: the area of the orifice; r: an orifice radius; v: a volume of the cavity; t is the depth of the hole, namely the plate thickness; d, the diameter of the hole.

Wherein L is t +0.8 d.

Since the air near both ends of the air column in the hole also participates in the vibration, t needs to be corrected, and the correction value is generally 0.8 d.

The cavity volume of the sound-insulating cavity 13, the thickness of the inner plate 12, the aperture of the sound-insulating holes 14 and the number of the sound-insulating holes 14 meet the sound-insulating frequency of the helmholtz resonator; when sound waves pass through the sound insulation holes 14 in the inner plate 12 of the sound insulation region 132, the air columns in the holes vibrate, and sound energy is consumed due to overcoming of frictional resistance in the vibration process, and finally the effect of sound insulation is achieved.

Further, the outer plate 11 is made of high-temperature-resistant, flame-retardant and waterproof plastic, so that the effective waterproof rainwater can enter the shell 1 to wet the sound-absorbing cotton on the inner layer.

Further, the material of the bottom plate of 3 tank bottoms in waterproof groove is waterproof material, can effectually prevent that chassis ponding from soaking puigging 2, prevents that wet puigging 2 from using compressor and pipeline problem of corroding for a long time.

Further, the partition 131 is long, one end of the partition 131 in the width direction is connected to the inner plate 12, the other end is connected to the outer plate 11, and the partition 131 extends from the top end to the bottom end of the case in the length direction.
