The present invention relates to a tri-con acoustic sensing unit and a location tracking system using the same. The tri-con acoustic sensing unit comprises: a body unit mounted on a base; an acoustic sensing unit which is mounted on the body unit, and collects an acoustic signal; an amplifying unit which is mounted on the body unit, and amplifies the acoustic signal collected from the acoustic sensing unit; a connector which delivers power received from the outside to the amplifying unit and the acoustic sensing unit, and includes an output terminal which delivers the amplified acoustic signal to a central control center of the outside; and an impact reducing member which is interposed between the base and the body unit by being connected to the outer rim of the body unit, and reduces impact delivered from the base. The present invention relates to the tri-con acoustic sensing unit and the location tracking system using the same, capable of stably obtaining the sound of an audio frequency range (20 Hz to 20 KHz) without performance reduction through a triangularly arranged condenser microphone and a delta tron amplifier circuit. The tri-con acoustic sensing unit includes the body unit of a metal material in which an O-ring band is attached to correspond to electric noise and physical impact. |
