Sound is converted to the signal of telecommunication, and stethoscope is wired or wireless connection with exterior terminal；Environment in order to effectively eliminate air transmitted is made an uproar
Sound, is provided with noise reducing microphone 311 on upper shell 1 or lower house 2；If stethoscope and exterior terminal are wired connection, enter one
Step noise reducing microphone 311 may also be arranged on connect exterior terminal cable 30 on, noise reduction mode be then by the signal of microphone 4 with
The signal of noise reducing microphone 311 is processed in the lump, eliminates noise for example with subtractive method of the prior art etc., this area
Technical staff can select as required.
Further contemplate fricative when stethoscope uses, bone-con-duction microphone 312 can be set in upper shell 1 or lower casing
To eliminate fricative on body 2, equally, noise reduction mode can use subtractive method etc., and it can cooperate into one with noise reducing microphone 311
Step promotes stethoscopic signal to noise ratio；And noise reducing microphone and bone-con-duction microphone only arrange one also dependent on needs.
Further embodiment includes passive denoising structure, wherein cavity cover 6 and lower house 2 compact siro spinning technology and stethoscope
Film 3 is encircled into the poly-operatic tunes, and microphone 4 is placed in the poly-operatic tunes by shock bracket 5 and is fixed on the central position of cavity cover 6,
Through hole 62 from cavity cover 6 for the wire (not shown) of connection microphone 4 is drawn along the first groove 61 after stretching out, through hole
62 is also that gas passage makes the poly-operatic tunes can connect with outside the poly-operatic tunes simultaneously, and this stethoscope farther includes cage 7, and it sets
Being equipped with the second groove 71, cage 7 is located at outside cavity cover 6 in the way of making groove 71 align with the groove 61 on cavity cover
