Referring to fig. 1 to 6, the present utility model provides an interrogation terminal 100, and in an embodiment of the present utility model, the interrogation terminal 100 includes a computer body 10, a display module 30, a speaker 50 and a buffer 70. The computer body 10 comprises a main casing 11 and a main control board 13, wherein the main control board 13 is arranged on the inner side of the main casing 11; one side of the display module 30 is rotatably connected to the outer side of the main control board 13; the loudspeaker 50 is arranged on the inner side of the main machine shell 11 and is electrically connected with the main control board 13, and the main machine shell 11 is provided with a sound passing hole 11a at a position corresponding to the loudspeaker 50; the damper 70 is provided between the junction of the horn 50 and the main housing 11.

The computer body 10 may be used as a main body of the interrogation terminal 100, and a main body casing in the computer body 10 may be used to provide a receiving space to receive devices such as the main control board 13 and the speaker 50, so that the main housing 11 may protect the devices located in the main housing 11. The main machine shell 11 may have a square or rectangular structure, so that the main machine shell 11 is regular in shape, thereby being beneficial to improving convenience in processing and forming the main machine shell. In addition, in order to facilitate forming the accommodating space of the main housing 11, the main housing 11 may further include at least two sub-housings. At this time, the split sub-housings can be processed independently, and then assembled to form an integral main housing 11. The main control board 13 can permanently control the operation of the interrogation terminal 100, for example: the loudspeaker 50 can be controlled to play related audio files, and the display module 30 can be controlled to display various files (including documents and videos) and the like. In addition, in order to facilitate law enforcement personnel to input relevant control instructions to the audit terminal 100, the main housing 11 is provided with a plurality of keys 15, and the plurality of keys 15 are electrically connected to the main control board 13. The display module 30 may display various files (including documents and videos) and the like as described above. Referring to fig. 1, fig. 2, and fig. 9, the display module 30 may include a first display screen 31 and a second display screen 33.
