Baffle vibration reducing

A loudspeaker system comprising:

• a baffle adjacent to a listening area, a source of electrical signals, a first transducer having a diaphragm, said diaphragm being moveable along a first axis, wherein said first transducer is mechanically connected to said baffle and wherein a first side of paid diaphragm is directly acoustically coupled to said listening area;
• a second transducer having a mass, said mass being moveable along a second axis wherein said second axis is substantially similar to said first axis and wherein said first transducer and said second transducer are structurally coupled;
• and
• wherein, when said source of electrical signals is electrically coupled to said first transducer and said second transducer, said first diaphragm and said mass are caused to move substantially in phase opposition thereby reducing a total force applied to said baffle by said first transducer and said second transducer.

A vibration reducing apparatus comprising:

• a baffle defining a mourning plane;
• a first transducer seated in said baffle, said first transducer having a first moveable assembly comprising at least a first transducer diaphragm wherein said first transducer diaphragm has two sides, wherein a first side of said first transducer diaphragm is directly acoustically coupled to a listening area and a second side of said first transducer diaphragm is coupled to a first volume;
• a second transducer mounted in a second plane different from the plane defined by said baffle, said second transducer having a second moveable assembly characterized by a moving mass, wherein said second transducer is not acoustically coupled to said listening area;
• and
• wherein said second transducer is mechanically coupled to said first transducer, wherein said first transducer and said second transducer are capable of accepting a signal input causing motion of said first moveable assembly and said second moveable assembly and wherein acceptance of said signal input results in mechanical out-of-phase relative motion of said first moveable assembly and said second moveable assembly.

A vibration reducing apparatus comprising:

• a baffle defining a mounting plane;
• a first transducer seated in said baffle, said first transducer having a first moveable assembly comprising at least a first transducer diaphragm, wherein a first side of said first transducer diaphragm is directly acoustically coupled to a listening area and a second side of said first transducer diaphragm is coupled to a first volume;
• a second transducer mounted in a second plane different from the mounting plane defined by said baffle, said second transducer having a second moveable assembly comprising at least a second transducer diaphragm, wherein a first side of said second transducer diaphragm is coupled to a second volume and a second side of said second transducer diaphragm is acoustically coupled to at least one acoustical element, said at least one acoustical element further coupled to said listening area;
• and
• wherein said second transducer is mechanically coupled to said first transducer, wherein said first transducer and said second transducer are each capable of accepting a signal input causing motion of said first moveable assembly and said second moveable assembly and wherein acceptance of said signal input results in mechanical out-of-phase relative motion of said first moveable assembly and said second moveable assembly.

Vibration reducing apparatus comprising:

• a baffle defining a mounting plane;
• a first transducer seated in said baffle, said first transducer having a first moveable element comprising at least a first transducer diaphragm, wherein a first side of said first transducer diaphragm is directly acoustically coupled to a listening area and a second side of said first transducer diaphragm is coupled to a volume;
• a second transducer mounted in a second plane different from the mounting plane defined by said baffle, said second transducer having a second moveable element comprising at least a second transducer diaphragm, wherein a first side of said second transducer diaphragm is coupled to said volume and a second side of said second transducer diaphragm is indirectly acoustically coupled to said listening area;
• and
• wherein said second transducer is mechanically coupled to said first transducer, wherein said first transducer and said second transducer are each capable of accepting a signal input causing motion of said first moveable element and said second moveable element and wherein acceptance of said signal input results in mechanical out-of-phase relative motion of said first moveable element and second moveable element.
