Abstract

A simple sound-direction quick-recognition device comprises a sound collection module. Output of the sound collection module is connected with input of a signal conditioning module, output of the signal conditioning module is connected with input of a main control CPU, and output of the main control CPU is connected with a liquid crystal display module and an acousto-optic hint module. The main control CPU is further connected with a keyboard module. A power supply module supplies power for the sound collection module, the signal conditioning module, the main control CPU, the liquid crystal display module, the acousto-optic hint module and the keyboard module respectively. Signals passing through the sound collection module enter the signal conditioning module, and are converted after being subjected to amplification and filtering, the converted result is sent to the main control CPU to be detected, and if the signals are detected, calculation is conducted, the calculated result is sent to the liquid crystal display module to be displayed and is sent to the acousto-optic hint module to conduct sound hint and LED lamplight hint at the same time. The simple sound-direction quick-recognition device is high in practicability, low in cost, high in reliability and accuracy, simple in operation and high in expandability.

Description

technical field [0001] The invention relates to the technical field of sound source localization, in particular to a simple and fast identification device for sound direction. Background technique [0002] Sound source localization is to quickly determine the position of the sound source in space. The sound source localization device based on the microphone array has a wide range of application values ​​in military and life. Most of the current spatial sound recognition is based on the design of microphone sensors, which have defects such as insufficient recognition accuracy, large volume, and difficult promotion. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the object of the present invention is to provide a simple and fast identification device for sound orientation, which is simple in structure, portable and low in cost. [0004] In order to achieve the above object, the technical scheme that the present in...
