The specific embodiment

Embodiment 1: in conjunction with Fig. 1, Fig. 6, Fig. 7 and Figure 12 this utility model is described further

The fit structure of two-band stethoscope film and can body comprises can body 1, C type seal ring set 2 and film 3;

Can body 1 is provided with and the cavity 4 that cooperates rotating shaft to rotate, and can body 1 is provided with sound collecting surface 5, is provided with the voice guide hole 6 and the rotating shaft fixing hole 14 that connect cavity 4 and sound collecting surface 5 on can body 1;

C type seal ring set 2 is with can body 1 and film 3 sealing and fixing, and can body 1 forms collection sound chamber 7 with film 3;

Wherein, film 3 comprises diaphragm 9 and rubber sleeve 8; Rubber sleeve 8 is linked to each other by a spherical zone body 12 by the ring belt 11 of two diameter differences, parallel and dead in line, and the outer edge of the ring belt 11 that diameter is bigger also is provided with the ring-type tight loop 10 perpendicular to ring belt 11; The outer rim of film 3 embeds in the less circular endless belt 11 of diameter;

Also be provided with ring-type convex shoulder 13 at the less ring belt 11 of diameter towards a side of the bigger ring belt 11 of diameter.

Wherein ring-type convex shoulder 13 can be various cyclic:

As can be known in conjunction with Fig. 1 and Fig. 7, ring-type convex shoulder 13 can be the cross section be U-shaped formation continuously and the ring of sealing.

As can be known in conjunction with Fig. 2 and Fig. 8, ring-type convex shoulder 13 can be the cross section be circular formation continuously and the ring of sealing.

In conjunction with Fig. 3 and Fig. 9 as can be known, ring-type convex shoulder 13 can be to be the ring that seals continuously that triangle forms by the cross section.

In conjunction with Fig. 4 and Figure 10 as can be known, ring-type convex shoulder 13 can be to be the ring that seals continuously that tetragon forms by the cross section.

In conjunction with Fig. 5 and Figure 11 as can be known, ring-type convex shoulder 13 can be the ring that seals continuously that is formed for the C type by the cross section.

During use: the person's of seeing a doctor visceral motility sound is sent to collection sound chamber 7 via film 3 with sound, and through hole 6 is sent to the voice guide hole of the rotating shaft that is rotatably assorted with can body cavity 4 with sound again, is sent to user by flexible pipe at last.

When user need be listened to the sound of different audio frequency, only need diaphragm 9 is depressed or diaphragm 9 do not depressed, make the convex shoulder 13 on the film 3 contact with sound collecting surface 5 or not contact, realized changing the space in collection sound chamber 7, thereby reached the purpose that changes the sound of listening to different audio frequency with sound collecting surface 5.

Because convex shoulder 13 is U types, so there are 2 contact surfaces in convex shoulder 13 with sound collecting surface, make when listening to sound, make the sealing of the 7 pairs of sound in collection sound chamber stronger.

In conjunction with Fig. 8, Fig. 9, Figure 10 and Figure 11 as can be known, wherein convex shoulder 13 can also be the cross section be the U type or the cross section for circle the cross section be leg-of-mutton or the cross section be tetragonal or the cross section be the C type continuously and closed round ring.
