Problems solved by technology
[0003] Commonly used audio detection devices need to manually detect the diaphragm, and collect and judge the working data of the diaphragm. The operation is more cumbersome and manual detection, the data accuracy is low, because the emission of sound waves will generate a certain amount of heat, sound waves as a kind of energy , the higher the energy dissipated, the higher the heat will affect the use of other components of the smart TV, and the unqualified products will dissipate higher heat than the qualified products under the same power. In order to solve the above problems, the inventor proposes In order to solve the above problems, the inventor proposed a sound detection device using magnetorheological fluid

The invention relates to the technical field of intelligent equipment detection, and provides an acoustic detection device using magnetorheological fluid, including an acoustic detection device. The left and right sides of the acoustic detection device are fixedly connected with magnetorheological fluid suspensions. The center of the detection device is fixedly connected with a sound source drive, the left and right sides of the sound detection device are fixedly connected with a detection frame, and the inner side of the sound detection device is fixedly connected with an audio component through the detection frame. The audio detection device, when the audio components work normally on the inside, the detection outer frame is a closed space, the air inside the detection outer frame is heated, and through the principle of thermal expansion and cold contraction, the temperature of the air inside the detection outer frame rises, and the outer detection frame The inside of the frame expands and squeezes the air, the air is sucked from the folding frame, and the air flow passes through the ventilation tank into the temperature measuring device. By observing the temperature rise data of the thermometer, it is possible to detect whether the heat resistance of the material of the audio component and the heat released are normal.
Description
technical field [0001] The invention relates to the technical field of intelligent equipment detection, in particular to an acoustic detection device using magnetorheological fluid. Background technique [0002] Smart TV is a new product based on the impact of the Internet wave. Its purpose is to bring users a more convenient experience. It has become the trend of TV at present, and audio is also one of the more important components of smart TV. Whether the sound of the audio is normal or not? It indirectly affects the user's perception of receiving information from smart TVs, and it is more important for the detection of audio sounds. [0003] Commonly used audio detection devices need to manually detect the diaphragm, and collect and judge the working data of the diaphragm. The operation is more cumbersome and manual detection, the data accuracy is low, because the emission of sound waves will generate a certain amount of heat, sound waves as a kind of energy , the higher...
