Abstract

The invention aims to provide the single horn acoustic test box which is convenient to operate, good in sound insulation performance and capable of creating a good test environment. The box comprises a lower box body and a sound insulation cover, a test microphone is arranged in the lower box body, a sound insulation layer is arranged on the inner wall of the lower box body, the sound insulation cover is arranged on the lower box body through a lifting device, a product placing piece is arranged on the upper end face of the lower box body and located below the sound insulation cover. A test port communicating with the interior of the lower box body is formed in the product placing piece, and the test port matches the test microphone. The invention is applied to the technical field of test boxes.

Description

technical field [0001] The invention relates to the technical field of test boxes, in particular to a single speaker acoustic test box. Background technique [0002] With the improvement of economic level, people's living standard is getting better and better. As an indispensable object in modern society, electronic products have brought great convenience to people's life. Electronic products need to be tested for performance after they are produced, and the speaker of the electronic product needs to be tested in an acoustic test box. After the speaker is powered on, the acoustic test software sends a test execution command to make the speaker emit sound in various frequency bands such as low frequency, intermediate frequency and high frequency, and then collect and analyze the sound wave information through the microphone, and output the waveform diagram. [0003] At present, the acoustic test soundproof box of the single speaker on the market still has the problem of poor...
