Large-scale loudspeaker shielding box

Abstract

The invention discloses a large-scale loudspeaker shielding box, aiming to provide a large-scale loudspeaker shielding box which is convenient in structure and stable and durable in use, and has good sound insulation performance. The shielding box includes a box body and a box door (1), the box body includes an inner shielding box and an outer shielding box, the inner surface of the inner shielding box is covered by a sound absorbing wedge (2), a sound insulation board is arranged between the inner shielding box and the outer shielding box, the two sides of the sound insulation board are provided with fireproofing environmental protection and sound insulation cotton, a clamp installing base (3) is arranged inside the inner shielding box, and a connecting panel (4) is arranged on the box body. The large-scale loudspeaker shielding box is applicable to the technical field of large-scale loudspeaker test.

Description

technical field [0001] The invention relates to a shielding box, in particular to a large loudspeaker shielding box. Background technique [0002] Speakers are not only an important means for electronic equipment to interact with people, but also a necessary hardware for creating high-quality music. In the quality test of loudspeakers, especially large loudspeakers, due to their characteristics, they are easily disturbed by external sounds and must be carried out in a relatively stable and quiet sound field. After producing good speakers, they must pass professional factory inspection before they can be sold. In this link, the general factory will set up a special test room and use equipment such as sound insulation walls. Although it can reduce sound attenuation to a certain extent and improve the accuracy of inspection quality, but because the test room is too large, it is easy to cause reverberation and affect the quality of the test. At the same time, the test room take...

Problems solved by technology

After producing good speakers, they must pass professional factory inspection before they can be sold. In this link, the general factory will set up a special test room and use equipment such as sound insulation walls. Although it can reduce sound attenuation to a certain extent and improve the accuracy of inspection quality, but because the test room is too large, it is easy to cause reverberation and affect the quality of the test. At the same time, the test room takes up a lot of field space, which increases the work cost, and when the test staff operates indoors, it is easy to cause certain damage to their own eardrums. harm

In order to reduce costs, some manufacturers adopt box-type detection, but they are too pursuing high integration and cost considerations, ignoring the detection accuracy and convenience
