Abstract: A dual mode communication device includes primary and secondary communication modules for transmitting first and second communication signals, a simulated switch, a microphone and a speaker. When the primary and secondary communication modules transmit one of the first and second communication signals, the simulated switch receives a switch control signal, thereby allowing the microphone to transmit an initiating signal. When the speaker receives a respective one of the primary and secondary switch control signals, the speaker outputs the respective one of the first and second communication signals with signal strength greater than the preset signal strength of the respective one of the first and second communication signals.
