Communication apparatus and portable telephone
First Claim
1. A communication apparatus comprising:
- an antenna for transmitting and/or receiving a wireless signal, a signal processing circuit for processing a signal corresponding to a wireless signal received by the antenna, a conductive case surrounding and housing all or part of the signal processing circuit, an electro-magnetic wave absorber permanently affixed with one surface adjacent a predetermined area of the conductive case for absorbing electro-magnetic waves emitted from the conductive case in a direction of a user and thereby reducing electro-magnetic waves reaching the user of the communication apparatus, a conductive member provided at another surface of the electro-magnetic wave absorber and being electrically connected to the conductive case, and further wherein the electro-magnetic wave absorber is physically located between a speaker of the communication apparatus and the conductive case, the conductive member being located closest to the speaker further comprising an outer housing separate from said conductive case, which surrounds and confines said conductive case, said electro-magnetic wave absorber, a microphone, said signal processing circuit, and said conductive member; and
wherein said electro-magnetic wave absorber is permanently secured to a fixed position at a side of the conductive case.
