Description
Technical field
The utility model belongs to acoustics signal processing field, particularly a kind of sound directing device.
Background technology
Sound is that we obtain very important a kind of carrier in external information.When you are just walking at a noisy the street, hear suddenly have people when being your name, you labour contractor can turn to sound source in spite of oneself, this is because the mankind have very strong sound source direction ability, are a kind of basic skills of people to environment sensing to the identification of sound bearing.
In reality, in a lot of application scenario, people need to complete this function of sound localization by sonic transducer, at this moment just need to use auditory localization technology.Auditory localization technology utilizes sonic transducer to pick up voice signal, and carries out treatment and analysis with Digital Signal Processing to it, then determines and follow the tracks of a special kind of skill of locus of sound source.People are long-standing for the research of sound, and the feature such as size, frequency spectrum of sound can reflect many features such as direction, positional structure of acoustic target.Along with the development of radio sensing network and electronic technology, auditory localization technology because of its cost low, security is high, disguised advantages of higher, obtains develop rapidly in military and civilian field.
Sound directing device complex structure of the prior art, volume is large, and the way of output is single, poor sensitivity, can not meet the sound directional process job requirement of high precision portable use.
Summary of the invention
For solving prior art Problems existing, the purpose of this utility model is to provide a kind of sound directing device, overcomes sound directing device complex structure in prior art, and volume is large, and the way of output is single, the technical matters of poor sensitivity.
For achieving the above object, the technical scheme that the utility model provides is:
A kind of sound directing device, comprise housing, be provided with Single-chip Controlling processing module and accumulator in housing, Single-chip Controlling processing module is connected with power transfer module, microphone sensor array module, radio receiving transmitting module and RS232 module, and accumulator is connected with power transfer module.
Described LED display module comprises 30 LED, and 30 LED are at housing outer face angularly annular array.
Described accumulator is connected with power switch and charge port.
Described radio receiving transmitting module is 433MHz radio-frequency module, comprises CC1101 radio frequency chip and antennal interface; Described Single-chip Controlling processing module is MSP430F1611.
Described sound directing device also comprises a tripod.
The utility model has the following advantages:
Compared with existing location technology, sound directing device inner structure of the present utility model is simple, easy to operate; The utility model volume is little, lightweight, can under varying environment occasion portable use; The utility model adopts muli-sounds mode signal output, and as wireless output, wired output, LED export, the multiple way of output meets multi-usage of the present utility model and uses.
Accompanying drawing explanation
Fig. 1 is schematic block diagram of the present utility model;

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further detailed.
A kind of sound directing device as illustrated in figs. 1 and 2, it is characterized in that: comprise housing, Single-chip Controlling processing module and accumulator is provided with in housing, Single-chip Controlling processing module is connected with power transfer module, microphone sensor array module, radio receiving transmitting module and RS232 module, accumulator is connected with power transfer module, and described accumulator is connected with power switch and charge port.Described LED display module comprises 30 LED, and 30 LED are at housing outer face angularly annular array.Described radio receiving transmitting module is 433MHz radio-frequency module, comprises CC1101 radio frequency chip; Described Single-chip Controlling processing module is MSP430F1611.Described sound directing device also comprises a tripod.
Introduce using method of the present utility model below:
First tripod of the present utility model is divided together with survey part and be placed on more spacious place, avoid peripheral acoustic reflection.
Power-on, the work of directed survey sound starts, if now there is abnormal sound in the external world, the utility model will pass through microphone sensor array by transmission sound to Single-chip Controlling processing module, single chip processing module is determined by the delay inequality of each sensor that sound arrives in microphone sensor array and is followed the tracks of the locus of sound source, then the result calculated is delivered to user by radio receiving transmitting module, RS232 mode.Meanwhile, LED display module of the present utility model can show Sounnd source direction, intuitively accurately.
User can apply this sound source direction device multi-usage, such as: army or the civilian location tracking system according to sound source; The camera of the band The Cloud Terrace of safety-security area, the target direction that need be able to rotate as The Cloud Terrace according to the utility model orientation; Electronic toy market needs the direction of motion and movement locus etc. by sound determination toy.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model instructions to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
