System, apparatus and methods for coupling a voice coil assembly and diagrapham for acoustic transducer

A system comprising:

• a diaphragm configured for radiating acoustic signals, the diaphragm having a first face and a second face;
• a roll surround disposed around a perimeter of the first face of the diaphragm;
• a modal coupling apparatus comprising a plurality of connecting arms and a central body, each of the plurality of connecting arms having a mounting foot, the modal coupling apparatus coupled to the second face of the diaphragm using the plurality of connecting arms, the central body having a shaped first end for receiving a voice coil former;
• a voice coil having a first end and a second end, the voice coil wound upon and secured to an outer surface on a first end of the voice coil former, a second end of the voice coil former placed within the shaped first end of the central body;
• and
• a positive electrical terminal and a negative electrical terminal, each terminal coupled to the voice coil for transmitting an electrical current through the voice coil upon receiving electrical power;
• wherein the voice coil is suspended within a magnetic field in an air gap, the air gap defined between a vertical portion of a motor return cup on a first end and a pole piece mounted upon a magnet on a second end, the magnet securely mounted onto an inner surface of the motor return cup,
• wherein the magnet generates a static magnetic field normal to a directional flow of the electrical current through the voice coil to generate an electromagnetic force on the voice coil upon the receiving of electrical power, the electromagnetic force producing a mechanical driving force acting on the diaphragm through the voice coil former and modal coupling apparatus.
