| 主权项 | 1. A handheld microphone including a microphone unit supported with a vibration insulator on a microphone case, the handheld microphone comprising a filter circuit for filtering output signals from the microphone unit; the filter circuit comprising a notch filter connected to an output terminal of the microphone unit, and a high-pass filter connected downstream of the notch filter and outputting filtered signals from the microphone unit, wherein the notch filter is a passive filter, wherein the high-pass filter is an active filter, and wherein the filter circuit absorbs vibratory noise from the vibration insulator and frequency response characteristics in a main sound pick up band are substantially flat. | ||
