Detailed Description

The present utility model is described below with reference to the accompanying drawings, and the specific embodiments described herein are for illustrating and explaining the present utility model, not for limiting the present utility model, and various modifications and improvements made by those skilled in the art to which the present utility model pertains without departing from the spirit of the design of the present utility model, should fall within the scope of the present utility model.

As shown in fig. 1 to 3, the noise-proof stethoscope of the present embodiment includes a stethoscope head 1, a sound-transmitting tube 2, an earplug 3, an earmuff 4, and a headband 5.

The sound transmission tube 2 is Y-shaped, the end part of the main tube 21 of the sound transmission tube 2 is connected with the stethoscope head 1, and the end parts of the two branch tubes 22 of the sound transmission tube 2 are respectively connected with one earplug 3.

The earmuffs 4 are provided in two, respectively at the ends of the branch tubes 22 of the sound-transmitting tube 2, outside the earplug 3. In particular, in this embodiment, the ear muff 4 has a hollow hemispherical structure, so that the ear muff 4 can be better contacted with the skin after being worn. The tube of the branch tube 22 of the sound transmission tube 2 connected with the earplug 3 is a straight tube 221, i.e. the part of the branch tube 22 connected with the earplug 3 is a straight tube, which is vertical to the side of the head of the human body, and correspondingly, the center of the surface of the earmuff 4 is provided with a through hole 7 for passing through the straight tube 221.

When the ear cup 4 is not required to be used, the ear cup 4 is divided into an upper ear cup 41 and a lower ear cup 42 in half in the radial direction thereof for convenience in taking out the ear cup 4 from the sound tube 2, and the upper ear cup 41 and the lower ear cup 42 are detachably connected.
