Abstract

A CHARGER SUITABLE FOR A STORAGE BATTERY IN A WIRELESS MICROPHONE COMPRISES A RECESS 12 FOR A LOWER-END PORTION OF THE MICROPHONE. A CIRCUIT BOARD 34 HAS ELECTRODES 36 AND 38 CONNECTED TO PLUNGERS 30 AND 32 IN THE BOTTOM SURFACE OF THE RECESS 12. THE PLUNGERS PROJECT INTO THE RECESS 12 BEING URGED BY A COIL SPRING. PROJECTION IS LIMITED BY AN ENLARGED PROTION 30A, 32A ON AN INTERMEDIATE PORTION. A FIRST COIL SPRING 40 IS COMPRESSED BETWEEN THE EXPANDED PORTION 32A AND THE ELECTRODE 38. AN INSULATING TUBE 42 WHICH HAS A TUBULAR ENLARGED PORTION 42A ON A LOWER PORTION AND HAS AN UPPER-END PORTION WHICH PROJECTS INTO THE RECESS 12 BUT WHOSE PROJECTION IS LIMITED IN A MANNER PERMITTING UPWARD AND DOWNWARD MOVEMENT ON THE UPPER-END PORTION OF THE PLUNGER 30. A SECOND COIL SPRING 44 IS COMPRESSED BETWEEN AN INTERMEDIATE EXPANDED PORTION 30A OF THE PLUNGER 30 AND THE ELECTRODE 36. A THIRD COIL SPRING 46 WITH WEAKER FORCE IS COMPRESSED BETWEEN THE EXPANDED PROTION 30A AND THE TUBULAR EXPANDED PORTION 42A.(FIG. 1)
