Fish eye form track device of sound resource
Using fish eye form five-quadrant sound sensor to make a tracking detector of the sound resource would be introduced in this paper. If a range wave reached the sound sensor, it would produce a voltage according to the strength of sound. If installed four sphere form sound sensor Ⅰ. Ⅱ. Ⅲ. Ⅳ in a fish eye form sphere, as Ⅰ. Ⅲ X coordinate and . Ⅱ Ⅳ Y coordinate, and installed a main sound sensor Ⅴ in centre of fish eye form, it would be consisted of a measured device of sound. When a range sound wave form sound source was plumb with the normal of main quadrant Ⅴ, the wave strength in the quadrant were equal, the sound source tracking detector would be produced same voltages in five sound sensors. When there is an angle between a range sound wave directions of emitted to the tracking head and the normal of sound sensor Ⅴ, as the strength of sound is different in five. We know the sounds direction according to the changes of the voltage in X andY. If the voltage in X andY can be adjusted by measure system, the sound source direction would be known.
five-quadrant sound sensor tracking detector of the sound resource fish eye form five-quadrant sound sensor sound sensors voltage differential connected.
