Question 30 Explain the operation of a dynamic microphone.
{"Image DocumentName": "Question 30Explain the operation of a dynamic microphone.", "Image ImageDescription": "A dynamic microphone consists of a coil of wire inside a magnetic field. (1) The coil is made to vibrate backwards and forwards by sound waves. This movement within the magnetic field produces an induced voltage that matches the variation in sound pressure. (1) Figure 2 shows the frequency response curve for a dynamic microphone. Question 31. From the data on the graph, what makes this microphone particularly suitable for use by a singer? The microphone is suitable because it has a linear response over the frequency range of the singer.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
