1. , for reducing a device for baffle vibration, comprising:

  • At least two electroacoustic transducers, each electroacoustic transducer has barrier film, and each barrier film is characterized by the axle of the movement defining described barrier film;

    The shell of at least two electroacoustic transducers described in support, each described axle is maintained predetermined direction relative to each other by described shell, wherein defines a chamber by described shell and described at least two electroacoustic transducers;

    Wherein when described electroacoustic transducer is by equal amplitude and when substantially in phase driving, the vector being applied to the wall of described chamber and the acoustics power at the end by the moving the inertia force generated and the pressure passed through caused by the movement of described barrier film of each at least two barrier films is zero substantiallyWherein said shell is attached to baffle plate, and described shell comprises;

    Have the front side conduit of front side end wall, the front side of the second barrier film in the front side of the first barrier film in described at least two barrier films and described at least two barrier films couples directly to described front side conduit;

    Have end wall on rear side of in the of first first on rear side of conduit, the rear side of described first barrier film couple directly to described first on rear side of conduit;

    AndHave end wall on rear side of in the of second second on rear side of conduit, the rear side of described second barrier film couple directly to described second on rear side of conduit,The vector of the acoustics power on rear side of the acoustics power on rear side of the acoustics power on the end wall of wherein said front side, described first on end wall and described second on end wall is zero substantially.
