发明名称 DETECTOR FOR ELECTRONIC STETHOSCOPE
摘要 FIELD: medical devices, in particular, electronic equipment for sound detection. SUBSTANCE: device has housing, resonator and electroacoustic transducer, which has cable which is mounted in housing. In addition device has unit for embracing cable jacket in point in which it is mounted in housing. Housing, resonator and embracing unit have direct acoustic contact to one another and are made from materials in which sound speed is greater than sound distribution speed in material of cable jacket, preferably metal, for example, steel. In addition weight of detector conforms to condition <EMI ID=0.261 HE=12 WI=21 TI=CHI>, where m is weight of detector, in kg, K is elasticity of human body, in N/m, F<SB>e</SB> is lower band of effective range of stethoscope, in Hz. EFFECT: . dwg
