Beschreibung
Zusammenfassung:	The utility model provides an infusion pump. The infusion pump comprises a loudspeaker, a control circuit, a loudspeaker driving circuit, a current detection circuit and a voltage output circuit. The input end of the current detection circuit is connected with the first output end of the loudspeaker driving circuit, the current detection circuit detects loop current flowing through the loudspeaker by the loudspeaker driving circuit, and the loop current forms a voltage difference between the input end of the current detection circuit and the output end of the current detection circuit; the output end of the current detection circuit is connected with the first input end of the loudspeaker, and the second output end of the loudspeaker driving circuit is connected with the second input end of the loudspeaker; the first input end of the voltage output circuit is connected with the input end of the current detection circuit, the second input end of the voltage output circuit is connected with the output end of th
