Abstract:
1. A radio communication device comprising: a communication unit that performs radio communication with an external device; a memory unit capable of storing first audio data; a distance estimation unit that estimates a distance from the external device serving as a transmission source which transmits a radio signal based on a predetermined condition related to a field intensity and a noise component of the radio signal received by the communication unit; a communication control unit that controls the communication unit to transmit an audio data transmission request to the external device serving as the transmission source based on the estimated distance estimated by the distance estimation unit, when the first audio data stored in the memory unit is being reproduced; and a reproduction control unit that adjusts a reproducing volume of the first audio data and a reproducing volume of second audio data that is decoded from a radio signal, when the first audio data stored in the memory unit is being reproduced and the communication unit receives the radio signal corresponding to the second audio data transmitted from the external device serving as the transmission source in response to the transmission request.
