the outer sleeve is provided with an axial through hole, one end of the big head is provided with an internal thread, the big head is screwed on the plug mounting seat, and the other end of the big head is provided with a joint for connecting a traditional stethoscope sound transmission system;
a speaker for converting an acoustic electrical signal into an acoustic signal;
and the nut is used for locking the conversion head during installation.
Further, the joint of the outer cover has a through hole in an axial direction, and the sound of the speaker is guided to the sound transmission system.
Further, at least one cone-shaped groove is formed in the connector, and the small end of the cone-shaped groove faces downwards, so that a sound transmission conduit of the sound transmission system can be conveniently sleeved in and prevented from slipping.
Further, the plug mounting seat is provided with a through hole and a cavity along the axial direction, one end of the through hole is provided with internal threads for screwing the plug onto the mounting seat, and the other end of the through hole is provided with a cavity for placing a loudspeaker.
Further, the size of the cavity is matched with the size of the loudspeaker, and the sound is completely transmitted to the sound transmission system of the traditional stethoscope through the through hole of the outer sleeve.
Further, the plug mounting seat and the outer sleeve are screwed together through the external threads at one end of the plug mounting seat and the internal threads at one end of the outer sleeve, and meanwhile the loudspeaker is pressed tightly.
Further, the plug mounting seat has a step near the plug mounting end for preventing the plug from sliding downward when the plug is fixed by the nut.
The utility model has the beneficial effects that:
the electroacoustic conversion head has the advantages of simple structure, convenience in processing and assembly and suitability for mass production; an electronic stethoscope auscultation mode consistent with the traditional auscultation mode is created, so as to solve the problems that the electronic stethoscope proposed in the background technology is inconvenient to auscultate directly and can not keep the auscultation mode of the traditional stethoscope.
