Wrist Phone With Improved Voice Quality

Abstract

A wrist phone with a single button includes a molded-plastic wristband and a wristband cap. A wireless transceiver module is mounted on a printed circuit board and is contained in a component cavity between the wristband and the wristband cap. A foil antenna is attached directly to the printed circuit board and extends between an outer layer and a wrist-facing layer of a flexible strap portion of the wristband. A microphone is located between the layers of the opposite flexible strap portion of the wristband at least two centimeters away from the wireless transceiver module. The single button is formed using the interleaved fingers of a landing pad on a surface beneath the inner surface of the wristband. The inner surface of the wristband is covered by a layer of conductive material that makes an electrical connection between the interleaved fingers when the outer surface of the wristband is pressed.

         21 . A device comprising:
 a wristband having a first wrist-facing layer, a second wrist-facing layer and a center wrist-facing layer all formed from a single piece of molded plastic;   a printed circuit board disposed adjacent to the center wrist-facing layer;   a wireless transceiver module mounted on the printed circuit board; and   a foil antenna extending from the first wrist-facing layer to the printed circuit board, wherein there is no connector between the foil antenna and the printed circuit board, and wherein the foil antenna has a slight meandering path adjacent to the first wrist-facing layer.   
     
     
         22 . The device of  claim 21 , wherein the foil antenna is directly attached to a strip pad on the printed circuit board. 
     
     
         23 . The device of  claim 21 , wherein the foil antenna is annealed to the first wrist-facing layer, and wherein the foil antenna is a flat foil band with a thickness of no more than 0.006 inches. 
     
     
         24 . The device of  claim 21 , wherein the foil antenna is laminated onto a flexible dielectric material, and wherein the foil antenna has a thickness of no more than 0.0012 inches. 
     
     
         25 . The device of  claim 24 , wherein the wristband is molded around the foil antenna on the flexible dielectric material. 
     
     
         26 . The device of  claim 21 , wherein the foil antenna is disposed between the first wrist-facing layer and an outer layer of the wristband. 
     
     
         27 . The device of  claim 21 , wherein signals received by the wireless transceiver module from the foil antenna do not traverse any rotating hinge shaft between the wristband and the wireless transceiver module. 
     
     
         28 . The device of  claim 21 , further comprising:
 a shielding layer disposed between the first wrist-facing layer and the foil antenna.   
     
     
         29 . A device comprising:
 a wristband having a first wrist-facing layer, a second wrist-facing layer and a center wrist-facing layer all formed from a single piece of molded plastic;   a printed circuit board disposed adjacent to the center wrist-facing layer;   a wireless transceiver module mounted on the printed circuit board; and   a foil antenna extending from the first wrist-facing layer to the printed circuit board, wherein the foil antenna is disposed between the first wrist-facing layer and an outer layer of the wristband, wherein there is no connector between the foil antenna and the printed circuit board, wherein the foil antenna has a thickness of no more than 0.006 inches, and wherein the foil antenna has a slight meandering path adjacent to the first wrist-facing layer.   
     
     
         30 . The device of  claim 29 , further comprising:
 a shielding layer disposed between the first wrist-facing layer and the foil antenna.
