A method including providing a first umbilical, coupling an end of the first umbilical to a first end of a compliant splice system, providing a second umbilical, and coupling an end to the second umbilical to a second end of the compliant splice system. The method further includes forming a plurality of solder bumps on the second electrode pads and putting the first substrate over the second substrate. In this device, signals of a frequency band over 20 kHz are reproduced by utilizing the split vibrations of the speaker diaphragm. The methods of the invention include syncing a wireless footswitch with a controlled device or a wireless footswitch adapter using a lower power wireless mode, then signaling the controlled device or wireless footswitch adapter using a higher power wireless mode. A number of management techniques are disclosed.
