声の伝達をするものである。However, in the magnetic resonance diagnostic apparatus, the subject must be placed in a static magnetic field with high uniformity in principle, and a magnetic substance such as iron that disturbs the magnetic field distribution cannot be placed in the scanning range. . In view of such circumstances, a device for transmitting sound using an air tube as disclosed in JP-A-60-207653 has been conventionally proposed. This is to arrange a means for irradiating a subject with an electromagnetic wave in a static magnetic field and a means for detecting a response to the electromagnetic wave in a room that is electromagnetically shielded, and is installed outside the room near the operator. The microphone, the speaker, and the amplifier are installed, and the air tube is provided between these and the subject to transmit the sound.
