Abstract: A retractable antenna for a communication device having an antenna receptacle includes a whip portion, including a conductive rod, and a connector, which includes a base portion of the conductive rod that is formed so as to be received and retained by the receptacle. Preferably, the base portion is bent so as to have a radial outer dimension greater than a radial inner dimension of the receptacle, so that the base portion is compressed radially when it is received by the receptacle.

Abstract: An electromagnetic vibrating motor requires certain criteria to perform its functions. Such criteria include: achieving high amplitudes from the driven motor when compared with the relatively restricted active gap of a simple electromagnet, the amplitude of the driven member should be unaffected by weight variations or changes in resiliently constraining forces, it should have a stationary member for suspending the system without imparting substantial vibrations to the vicinity, and it should be easily connected to driven member of the system. The present invention includes three masses. The first mass is a driven mass, the second mass is an electromagnetic member and the third mass is a magnetic member. These masses are connected together through springs in order to perform its necessary functions while meeting the required criteria.
