Mobile communication transmitter with free speech

摘要

The device has a first loudspeaker (L1) for emitting sound signals in normal operation, a second loudspeaker (L2) for hands-free mode, an antenna (A) and a signal processor (SV) for processing signals received by the antenna and feeding signals to the loudspeakers depending on the mode. In hands-free mode the signal processor feeds signals above 500 Hz to the first loudspeaker, which is designed to reproduce sound signals above 500 Hz. AN Independent claim is also included for the following: a method of radiating sound signals for a mobile communications terminal.
