A communication device is provided that includes a speaker for outputting a ringing signal, a microphone for receiving the ringing signal, and logic configured to analyze the spectral content of the received ringing signal and adjust noise reduction parameters and echo cancellation parameters based on the analyzed spectral content of the received ringing signal.

An electro-acoustic communications unit () may include an acoustic driver () which, when operated, emits acoustic waves in two directions. A hermetically sealed container () attached to the acoustic driver may include a gas other than air. The gas may transport acoustic waves generated by the acoustic driver.

The invention can allow data to be transferred from/to an electronic device when a removable Subscriber Identity Module (SIM) card that stores information used to register the electronic device with a communications network is absent from the electronic device. A subscriber may, therefore, upgrade from an existing radiotelephone to a new radiotelephone without the need for two SIM cards so that both radiotelephones operate to transfer the data. For example, according to embodiments of the invention, a subscriber can transfer data from the existing radiotelephone to the new radiotelephone even though one of the radiotelephones does not have a SIM card.

Methods, electronic devices and computer program products for transferring data stored in an electronic device when a subscriber identity module is absent therefrom

Communication terminals, methods, and computer program products are provided that sense background noise via a speaker that is also used to generate sounds. In some methods of operating a communication terminal, and a speaker signal is supplied to a first speaker to generate sound therefrom, a noise sensing signal is received from the first speaker. The noise sensing signal includes a contribution associated with background noise that is incident to the first speaker. Presence of the background noise in the noise sensing signal is determined.
