发明名称 Telephone system having reduced sensitivity to RF interference and related methods
摘要 A telephone to be connected to a wireline having reduced sensitivity to RF interference over a predetermined frequency range from an adjacent mobile wireless communications device may include a transmit amplifier, a receive amplifier, an audio input transducer connected to the transmit amplifier, and an audio output transducer connected to the receive amplifier. The telephone may further include an RF shield(s) surrounding the audio input transducer and the audio output transducer for reducing RF interference over the predetermined frequency range from the adjacent mobile wireless communications device. Moreover, the telephone may also include at least one RF audio input filter element connected to the audio input transducer and at least one RF audio output filter element connected to the audio output transducer, both of which are also for reducing RF interference over the predetermined frequency range from the adjacent mobile wireless communications device.
