| 摘 要： | 本系统是用MSP430G2452单片机产生频率为500Hz的方波信号,该信号用三极管进行放大及驱动后输入到扬声器作为声源。接收部分使用麦克风进行接收,再通过对四个麦克风接收到信号的时间先后进行处理,经过一套比较完善的算法可得声源的坐标,即可进行声源定位。然后经过后级的更精确的算法,当声源移动时,可实时检测到声源坐标。

| Abstract: | This system takes the square wave signal which frequency is 500 Hz and produced by MSP430G2452 microcontroller as the sound source which magnified and droved by the triode 9014, and then input to the speaker. Receiving part is to receipt by the microphone, we can get the sound source coordi- nates through processing the signal received by the four microphones according to time order and a set of relatively perfect algorithm. That is to say we can carry out sound source localization. When the sound source moves, we can achieve the coordinates of sound source thought the grade more accurate algorithm. |
