Abstract

The invention relates to an umbrella-shaped reconfigurable three-dimensional sensor array comprising a main array body and microphones installed on the main array body detachably. The main array body includes a mains shaft arranged horizontally; fixed ends of a plurality of connecting rods are arranged on the main shaft in a slidable mode; and free ends of the connecting rods radiates around the main shaft. A support rod for supporting is arranged at each connecting rod; one end of the support rod is arranged at the connecting rod in a slidable mode and the other end is hinged to the end portion of the main shaft. The main shaft, the connecting rods, and the support rods form an umbrella skeleton shape. The microphones are distributed on the connecting rods. When a sliding sleeve slides and the mounting positions of the microphones are adjusted, the microphone positions can be adjusted, so that an optimal position can be selected to obtain an optimal sound source identification and positioning effect. Moreover, a real or false sound source can be identified and a false sound source interference can be suppressed effectively.

Description

technical field [0001] The invention relates to an umbrella-shaped reconfigurable three-dimensional microphone array. Background technique [0002] The microphone array is an acoustic detection device that combines multiple microphones according to a certain geometric distribution. The device can detect multiple sound sources synchronously in combination with signal processing software, can measure the spatial information of the sound source, and can detect specific locations. The sound source performs signal enhancement and suppresses background interference processing, which can improve the equipment's ability to pick up the target sound, and can also be used to track the movement of the sound source. This device appears in most applications in the field of modern acoustic measurement, such as hearing aids, telephones Conference systems, computer terminal equipment, etc., are used to realize functions such as voice enhancement, sound source localization, acoustic imaging d...
