Abstract: An output control method of voice guidance signal in navigation system, the method comprising: searching for a travel route from a starting location to a destination of a vehicle; guiding the vehicle to travel along the searched travel route, and determining a current vehicle location if the vehicle is traveling, searching for a target location to be guided ahead of the traveling vehicle; generating a voice guidance signal for the searched target location to be guided; determining the priorities of a plurality of voice guidance signals in advance and outputting the voice guidance signals in sequence according to the predetermined priorities if the plurality of voice guidance signals conflict thereamong.

Abstract: A travel route stray discriminating method of a mobile object in navigation system is disclosed in which discrimination of travel route deviation is temporarily withheld even if the mobile object has deviated from the travel route on a busy road such as a cross-road, and a warning that the mobile object has deviated from the travel route is issued if it is accurately discriminated that the mobile object has strayed from the travel route.

Abstract: A method (200) and apparatus (100) that synchronizes audio levels of a device and an audio accessory is disclosed. In at least one embodiment, the apparatus (100) includes a housing (110) and a local speaker (130) coupled to the housing. The apparatus also includes a wireless speaker interface (180) coupled to the housing.

Abstract: A map scale changing method and apparatus for navigation system capable of automatically changing a map scale when a travel route of a mobile object is searched and displayed on a display screen, whereby a map scale is changed based on a distance between a current position of the mobile object and a search start position of the travel route when the mobile object starts to travel to allow both the current position of the mobile object and a start position of the travel route to be displayed a display screen, and a map scale is changed based on a distance between the current position of the mobile object and a real destination in case the mobile object approaches a search termination position of the travel route to allow both the current position and the destination to be displayed on the display screen.

Abstract: A directivity controlling apparatus and method of a microphone system for collecting audio signals in an audio recording/reproducing system. A certain microphone in the system is selected to have directivity according to a result of comparing levels of input signals supplied into plural partial microphones in a supervisory mode by categorizing directional microphones into a directional mode and the supervisory mode. An automatic shift operation is performed during the supervisory mode, in which audio signal levels received via the plural partial microphones are compared to select a certain microphone to have the specific directivity and, then, the input level of the particular microphone having the directivity is monitored to repeat the supervisory mode according to the monitored input level.
