Abstract
Official abstract text for this publication.
Provided is a narrow-angle directional microphone in which a microphone unit is attached to an acoustic tube, the acoustic tube is accommodated a microphone case and which prevents the rattling of components provided in the microphone case and has high mechanical strength. A narrow-angle directional microphone 1 includes a microphone unit 2 , an acoustic tube 3 that has an opening formed in a circumferential wall along an axis direction and a rear end to which the microphone unit is connected, a cylindrical microphone case 4 that accommodates the acoustic tube, and fixing means 3 a , 4 a , 10 , and 20 a that fix the acoustic tube in the microphone case, with stress being applied to the acoustic tube in the microphone case in the axis direction from the leading end side of the acoustic tube using the rear end of the acoustic tube as a fulcrum.
