Abstract

The invention provides a sound-insulating box for acoustic testing. The sound-insulating box comprises a wall body, a top plate and a bottom plate. A square sound-insulating chamber is defined by thewall body, the top plate and the bottom plate jointly. The wall body comprises a front plate, a rear plate, a left side plate and a right side plate. A sound-insulating door is arranged on the front plate and comprises an outer sound-insulating door body and an inner sound-insulating door body. The inner surfaces of the wall body, the top plate and the bottom plate are each provided with a boss, and the sizes of the bosses are smaller than those of the outer surfaces of the wall body, the top plate and the bottom plate correspondingly. The adjacent bosses can be matched in a concave-convex mode, and the wall body, the top plate and the bottom plate are fixedly connected through bolts. According to the sound-insulating box for acoustic testing, the structure is reasonable, carrying is convenient, the sound-insulating effect is good, the firm and durable effects are achieved, ventilating is good, and a comfortable and quiet environment is provided for operators.

Description

technical field [0001] The invention belongs to the field of sound insulation equipment, and in particular relates to an acoustic test sound insulation box. Background technique [0002] In recent years, with the rapid development of electronic products, consumers have higher and higher requirements for the quality of these products, and the testing of electronic products has become more and more cumbersome. Acoustic audio testing is an important part of functional testing of electronic products. In order to accurately test the audio performance of electronic products, the test process needs to be carried out in a soundproof room that is not affected by external noise. Soundproof rooms can also be used in machinery, air conditioning, medical and other fields. Most of the existing sound-proof rooms adopt reinforced concrete or gypsum board structure, which occupy a large area and are difficult to transport. The sound-proof room has poor ventilation and poor air quality, and ...
