The acoustic tube is composed of an elastic material. An adjustable member elongates and contracts the distance between the microphone unit and the front end of the acoustic tube. The acoustic tube is held by an acoustic-tube protector having openings on a peripheral wall thereof. The base end of the acoustic tube is integrated to the acoustic-tube protector, and the front end of the acoustic tube is connected to a sliding cylinder that is slidably fitted in the axis direction of the acoustic tube along the acoustic-tube protector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Highly directional microphone","description":"A highly directional microphone includes an acoustic tube and a microphone unit that is disposed inside the base end of the acoustic tube.
