Claims (6)

A stethoscope with a black diaphragm and a bell chest chest, which induces the vibration signal detected by the test piece described above to the microphone by a conduit, and converts the vibration signal into an electrical signal by the microphone. In addition, the radio transmission circuit device using the built-in battery as a power source may transmit the electrical and radio communication signals, and the radio transmission circuit device can receive and record and reproduce the transmission signal by the radio recorder device. An electric stethoscope configured to connect a plurality of headphones to receive the above-mentioned communication signal by providing a plurality of connection terminals at the terminals. 2. The battery and radio transmitting circuit device as set forth in claim 1, wherein the battery and the radio transmitting circuit device are integrated in a flat case body having a long section, and the conduit is protected and supported by a cap integrally in contact with the upper portion of the case body. At the same time, the bottom plate has a removable bottom plate connected to the chest piece, and a battery control switch is installed on the surface of the case body so that it can be operated from the outside. An electric stethoscope configured by installing an output terminal for signal transmission of a plurality of radio transmission circuit devices to be connected to the outside. The electric stethoscope according to claim 2, wherein the output terminal for signal transmission described above is used as a connection jack, and the switch main body is provided with a switch that can be controlled in the air by operation from the outside. The secondary shape according to claim 1, wherein the conduit described above is a three-way tube having an inverted Y-shaped flexibility, the upper opening of which is connected to the chest piece, and connected to the case body by a cap. An electric stethoscope configured to protect the other end of the opening of the microphone, and to attach the microphone to the second end of the secondary opening. According to claim 1, wherein the conduit is a hollow cylindrical shape, the center of the circumferential wall in the rectangular direction is a sleeve formed in communication with the communication hole in the linear direction in and out, and the connection portion of the chest piece transverse lumen To pierce the rotatable through hole, and to rotatably attach the sleeve to the through hole by screws that screw the two ends together, and to mount the microphones inside the respective screws in the sleeve and to rotate the sleeve. An electric stethoscope configured to allow the above-mentioned communication hole to pick up the vibration sound toward either the diaphragm side or the bell side. 6. The positioning means according to claim 5, wherein the outer peripheral portion of the sleeve and the inner peripheral portion of the through hole are provided with a positioning means for stopping the sleeve when the sleeve rotates to reach a predetermined position on the diaphragm side and the bell side, respectively. Electric stethoscope. ※ Note: The disclosure is based on the initial application.
