发明名称 Portable communications device
摘要 A portable communications device having a base that can be worn on the user's wrist, a wireless earpiece that can be concealed when worn, and a novel audio link that allows the earpiece to communicate with the base. Each audio link is programmed to communicate with any base unit of the present invention but with only one earpiece. The audio links and earpieces can be packaged and sold together, and the base units can be packaged and sold separately. The base includes a novel keypad having keys that are positioned around the periphery of the base in a sequence which matches that used on old rotary dial phones and which allows the user to access the keys without having to look at them. The earpiece includes the microphone into which the user talks. The microphone can easily detect and transmit the user's voice, yet is mostly concealed from passersby. Thus, the user can use the portable communications device while conducting other activities but without making it obvious to observers that he or she is using the device.
