发明名称 Directional listening device
摘要 A directional listening device includes a reflector having a central axis, a microphone pointing toward the reflector and positioned along the central axis, and a collimator or shield surrounding the microphone and aligned with the reflector for improved directionality. The device also includes a laser pointing away from the reflector and a fitting for receiving a sighting device for aiming the listening device. Handles attached to the listening device have a resilient cover for noise reduction.
