Embodiment Construction

[0019] In order to make the purpose and features of the present invention more comprehensible, the specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] Please refer to figure 2 , which is a schematic diagram of a power distribution structure provided by an embodiment of the present invention. As shown in the figure, in this embodiment, the distribution box is made into a sound-absorbing wedge shape, and the distribution panel is placed in the distribution box. Specifically, the power distribution structure has an enclosure 100 in the shape of a sound-absorbing wedge, and a power distribution panel 200 is disposed therein.

[0021] In this way, when the distribution box is installed in the anechoic chamber, the distribution board will not be directly exposed, which avoids the problem of sound waves being reflected by the distribution board and improves the sound absorption effect of th...

Abstract

The invention discloses a power distribution structure which comprises a shell of a sound-absorbing wedge shape and a power distribution panel arranged inside the shell. By arranging the power distribution structure in an anechoic chamber, the power distribution panel cannot be exposed outside directly, so that the problem that sound waves are reflected after encountering the power distribution panel is avoided and the sound absorbing effect of the anechoic chamber is enhanced. In addition, because the power distribution structure is consistent with a sound-absorbing wedge in shape, the entire anechoic chamber is more attractive.

Description

technical field [0001] The invention relates to the technical field of an anechoic chamber, in particular to a power distribution structure applied to an anechoic chamber. Background technique [0002] An anechoic chamber is a professional laboratory used in acoustic experiments, and it is widely used in various fields such as automobiles, aerospace, household appliances, computers and communications, industrial products, etc., to measure noise and acoustic characteristics of products. In order to perform these measurements, the anechoic chamber requires the establishment of a free sound field space, that is, in this space, the medium that propagates the sound wave extends infinitely in all directions uniformly, so that the sound energy radiated by the sound source can propagate "freely" without obstacles reflection, and no interference from environmental noise. In order to achieve the conditions of the anechoic chamber, strong sound-absorbing materials are often arranged o...
