SPEAKER CONNECT SYSTEM ~ UTILIZING CONDUCTIVE ELASTOMER

by David Karl

  Electronic devices requiring speakers are faced with the potential problems of integrating the speaker into the schematic.

  These problems include slide on clips that vibrate loose, or were not assembled correctly. Another method is soldering wires or flexes with the potential for poor solder joints. Both of these add labor. A third method has springs mounted to a circuit board that interconnect directly to the speaker. This approach requires extra parts.

  The method presented here eliminates many of the problems described above, while also reducing required parts and labor. To accomplish this the system takes advantage of three current design innovations.

  The first is a recent change by speaker suppliers from having the wires that drive the speaker suspended between the cone and the basket to now having these wires bonded to the cone and following the cone to wrap around its edge and go under the gasket to the basket. The rerouting of these v&s allows us to take advantage of the second innovation in speaker technology. This is the change 6om hard gaskets to sotI compressible gas- kets. These soft gaskets have the ability to have selective portions containing condu$ve carbon as shown in con- ductive keypad technolo&. The third innovative tech- nology used with this concept (but not required) is '3d' printed circuit technology. The abiity...
