The utility model relates to an acoustic emitting device of an acoustic logging instrument. In order to overcome the shortcomings that the sound wave signal energy decay of the acoustic emitting device in the existing acoustic logging instrument is larger, the structure of the emitting device is complex and is not easily disassembled, and the failure occurs easily during the use and the maintenance, the axial connection of a central shaft 1 (1) and a central shaft 2 (7) of the acoustic emitting device is provided with a carriage (4), a transmitting transducer (6) is fixedly arranged on the central shaft 1 (1), a high voltage transformer (2) is arranged on the central shaft 2 (7), and the transmitting transducer (6) is a sectional transducer. The number of the transmitting transducer (6) is 1, and the number of the high voltage transformer (2) is 1. The acoustic emitting device has the beneficial effects that the emitting energy of the acoustic emitting device is improved, the structure of the emitting device
