Description
Technical field
The utility model relates to a kind of communication technique field, particularly relates to a kind of sound source locating device.
Background technology
In modern war, sniper is threatening soldier's life with its surreptitious whereabouts and efficient killing-efficiency, the military or the police only have large-scale vehicle-mounted sound source sniffer at present, there is no small-sized portable sound source sniffer, soldier, in the time of individual combat, cannot carry, and just can not judge accurately at any time enemy's sound position, cannot make counte-rplan accurately, greatly increase soldier's danger coefficient.
Therefore, instantly need the urgent technical matters solving to be exactly: a kind of effective measures of proposition how can innovate, to meet the demand of practical application.
Utility model content
For the weak point existing in the problems referred to above, the utility model provides a kind of sound source locating device, and soldier can be carried, and can judge at any time enemy's sound source position, make in time accurate judgement, make counte-rplan, increase substantially soldier's safety coefficient.
In order to address the above problem, the utility model provides a kind of sound source locating device, comprise sound collection module, sound detection module, sound localization module and sound output module, one end of described sound detection module is connected with described sound collection module, the other end is connected with one end of described sound localization module, the other end of described sound localization module is connected with described voice output module, wherein, described sound collection module comprises the array of at least four microphone compositions, and is distributed on four angles of device; Described sound localization module comprises arithmetic element, and described arithmetic element is made up of Fpga chip.
Preferably, described sound detection module comprises filtering circuit unit and the sample circuit unit that series connection arranges.
Preferably, described voice output module comprises the audio output unit and the bluetooth unit that are arranged in parallel.
Compared with prior art, the utlity model has following advantage:
The utility model volume is little, being convenient to soldier carries, judge at any time enemy's sound source position, make in time accurate judgement, make counte-rplan, increase substantially soldier's safety coefficient, and by adopting low power dissipation design and excellent algorithm, realize super long standby time and miniaturization, can carry for a long time easily, need not worry again equipment electric weight deficiency and the too large problem of equipment.
