Abstract

A sound source orientation device is composed of a spherical surface sound sensor array installed on a base and a microcomputer module. Each sound sensor is installed in cylindrical tubes in the same size, the cylindrical tubes are evenly distributed on a sphere at equal interval, tube openings of the cylindrical tubes are outwards, centre lines of the cylindrical tubes direct to a sphere center, the sound sensors are installed at the bottoms of the cylindrical tubes, sensing ends right face to the tube openings, and each sound sensor corresponds to a position coordinate of the sound sensor on the spherical surface. Each sound sensor simultaneously sends position coordinates and received light strength to the microcomputer module, the microcomputer module finds out position coordinates of the sound sensor receiving maximum light strength, and the direction of the sound sensor is the direction of a sound source relative to the spherical surface sensor array. If a plurality of sound sensors receive sound with same strength in a same area, the direction directed by a ray passing through the center of the area from the sphere centre is the direction of the sound source.

Description

The sound source direction instrument

Technical field

A kind of sound source direction instrument.

Background technology

At present, owing to not having can be to the self-orientating device of sound source, the direction that anti-thefting monitoring equipment, fire-fighting safety supervision equipment, Classroom Record recording arrangement etc. can not obtain the object of sounding can not realize the target automatic tracing, affects the result of use of the said equipment.

Summary of the invention

The invention provides a kind of sound source direction instrument, this sound source direction instrument can detect sound source automatically with respect to the direction of himself, and can give the equipment that needs to use these data with this direction data feedback.

The technical solution adopted for the present invention to solve the technical problems is: this sound source direction instrument is comprised of the sphere sound transducer array and the micro computer module that are installed on the base, each sound transducer is contained in the identical cylindrical tube of size, cylindrical tube equidistantly is evenly distributed on the sphere, the mouth of pipe of cylindrical tube is outside, its center line points to the centre of sphere, sound transducer is installed in the bottom of cylindrical tube, its end of probe faces the mouth of pipe, the output line of each sound transducer all is connected with the signal input part of micro computer module, and each sound transducer correspondence its position coordinates on sphere.

Each sound transducer is passed to the micro computer module with the position coordinates of oneself with the intensity of the sound that receives simultaneously, the micro computer module is found out the position coordinates of the sensor that receives the intensity of sound maximum, this imparts acoustic energy sensor direction pointed namely is that sound source is with respect to the direction of this sphere sensor array, if the intensity of sound that the same area has the multi-acoustical sensor to receive is identical, then take the centre of sphere through the direction of the ray of this regional center direction pointed as the sound source place.

The invention has the beneficial effects as follows that the object that this sound source direction instrument can be sounded to all directions simultaneously carries out orientation, orientation quick and precisely.

(1) cylindrical tube among the figure, (2) sound transducer, (3) base, (4) sound source.

Embodiment

This sound source direction instrument is comprised of sphere sound transducer (2) array and the micro computer module that are installed on the base (3), each sound transducer is contained in the identical cylindrical tube (1) of size, cylindrical tube equidistantly is evenly distributed on the sphere, the mouth of pipe of cylindrical tube is outside, its center line points to the centre of sphere, sound transducer is installed in the bottom of cylindrical tube, its end of probe faces the mouth of pipe, the output line of each sound transducer all is connected with the signal input part of micro computer module, and each sound transducer correspondence its position coordinates on sphere.

Each sound transducer is passed to the micro computer module with the position coordinates of oneself with the intensity of the sound that receives simultaneously, the micro computer module is found out the position coordinates of the sensor that receives the intensity of sound maximum, this imparts acoustic energy sensor direction pointed namely is that sound source (4) is with respect to the direction of this sphere sensor array, if the intensity of sound that the same area has the multi-acoustical sensor to receive is identical, then take the centre of sphere through the direction of the ray of this regional center direction pointed as the sound source place.

More than disclosed only be the application's a specific embodiment, but the application is not limited thereto, the thinkable variation of any those skilled in the art all should fall in the application's the protection domain.
