NAVIGATION DEVICE, NAVIGATION METHOD, NAVIGATION PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A navigation device includes a 3D surround system (100) having a plurality of loudspeakers. A guide information acquisition unit (101) acquires information on a route guide. According to the information acquired by the guide information acquisition unit (101), a control unit (102) controls output of a guide sound so that the coming direction of the guide sound moves by simultaneously using at least two of the loudspeakers. Moreover, the control unit (102) controls the output of the guide sound by simultaneously using a low sound-dedicated loudspeaker (104) among the loudspeaker group (103) and the loudspeaker group (103).
