PURPOSE: To enable precise and detailed ausculation by direct contact of a trapezoidal part of the trapezoidal membrane resonator to a specimen requiring ausculation, and selectively using of a chest piece for a different ausculation sound band. CONSTITUTION: Depending on ausculation of the higher frequency band or of the lower frequency band, the chest piece of 10A, 10B, or 10C is selected for the higher or the lower frequency band. Each chest piece of 10A, 10B, or 10C is attached to the respective fixed holes 12a, 12a, 12a of the rotating outer tube 12, and when one of the connecting hole 10e of each chest piece 10A, 10B, or 10C is agreed with the 3 way hole 31 of the receiving inner tube by using the positioning measure 34, the interior sound obtained by resonance is received by the microphones 30, 30 and is input to the electrical circuit of the housing through the electrical cord 35. When requiring adjustment of sound band of ausculation at the higher or the lower frequency band, the chest piece of 10A, 10B, or 10C is exchanged by rotating the rotating outer tube 12.
