Detailed Description

The following detailed description of the present utility model clearly and fully describes the technical solutions of the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model provides a auscultation loudspeaker through improvement, and the technical scheme of the utility model is as follows:

as shown in fig. 1-5, an auscultatory loudspeaker comprising:

a sound guide tube 1;

the connecting pipe 2 is sleeved at one end of the sound guide pipe 1;

miniature microphone 11, miniature microphone 11 sets up in sound guide tube 1 and keeps away from connecting pipe 2 department, sound guide tube 1 is close to connecting pipe 2 department and is provided with megaphone 7, and megaphone 7 and miniature microphone 11 electricity are connected, still include controller 8, controller 8 and megaphone 7 and miniature microphone 11 equal electric connection, still include wire 9, wire 9 sets up inside sound guide tube 1, wire 9 is used for connecting miniature microphone 11, controller 8 and megaphone 7, still include battery 6, battery 6 sets up in sound guide tube 1, battery 6 is connected with megaphone 7 and miniature microphone 11 electricity.

The silver wire is used as the lead 9 to transmit the electric signal, so that the accuracy of sound conduction is ensured, and meanwhile, the stability of electric signal conduction is ensured through wired transmission, so that the electric signal is not easy to be interfered by the outside.

Further, the sound insulation cotton 10 is filled between the loudspeaker 7 and the miniature microphone 11 in the sound guide tube 1, one end of the sound guide tube 1, which is far away from the connecting tube 2, is provided with the stethoscope head 5, the connecting tube 2 is of a three-way structure, and both ends of the connecting tube 2, which are far away from the sound guide tube 1, are respectively sleeved with the ear hook 3.
