    摘要: A wireless communication device (50) can include a radio frequency transceiver (52), an audio drive circuit (58) coupled to the transceiver, a speaker (10) having a voice coil (16) coupled to the audio drive circuit, and an antenna feed or radiating circuit (20) such as an RFID or NFID circuit coupled to the voice coil for at least radiating or receiving an electromagnetic signal via the voice coil. Such radiating circuits can be coupled to the voice coil using a band pass circuit designed to substantially prevent a radiating signal from the radiating circuit from interfering with audio drive circuit driving the speaker. The wireless communication device can further include an antenna (54) coupled to the radio frequency transceiver. Note, this arrangement can be designed to avoid problems involving electrostatic discharge sensitivity, electromagnetic interference coupling between the antenna and the voice coil, total radiated power, and specific absorption rate.

    摘要: A communication device (102) has a loudspeaker (212) that includes a loudspeaker coil. The loudspeaker is used for playing audio signals and for detecting metal in the vicinity of the loudspeaker. To detect metal the communication device includes a pulse generation circuit (216) for generating pulses that are applied to the loudspeaker, and a pulse measurement circuit (222) for measuring response pulses. If the response pulses indicate metal is in proximity to the loudspeaker, an alert is generated to inform the user of the communication device.

    摘要: A wireless device (100) includes an electrical circuit arrangement (200) for deterring access to an electrical signal having a predictable electrical pattern. The circuit arrangement (200) includes a processor (206) for processing instructions and a controller (210) communicatively coupled to the processor (206) and able to send at least one signal along each of a plurality of signal lines from within the circuit (200).

    摘要: A mobile communication device (100) includes a volatile memory (110) and a non-volatile memory (112). Instruction code for operating the mobile communication device is permanently stored in the non-volatile memory, and copied to the volatile memory for execution. The mobile communication device enters a hibernate mode which involves shutting down most of the mobile communication device except power to the volatile memory, which allows a nearly instant apparent start up of the mobile communication device at a later time.

    摘要: The invention concerns an accessory (112) for coupling to a portable electronic device (110). The accessory includes an interface (120) for coupling to the portable electronic device, an identifier (124) in which the identifier generates at least in part a parameter and at least one speaker (128). Only if the accessory contains more than one speaker, the parameter generated at least in part by the identifier causes an audio amplifier (148) that drives one of the speakers to be activated. In addition, the parameter generated at least in part by the identifier can cause the audio amplifier to be deactivated if the accessory contains only one speaker.
