摘要：
A communication system especially for coaching swimmers comprises a hand set which the coach uses to summon up a swimmer or swimmers to be instructed by means of generated tones and a thing worn by each swimmer to be instructed which contains electronic amplifying means and audio transducers. To water proof the electronics they are enclosed in a sealed enclosure and then in the latex of a swimming cap. Batteries used in the circuitry can be recharged without breaking the sealing by using a strong magnetic field to break through the water-proofing and drive a constant current battery charging arrangement.
