Equatorial positions and 0 ° are nested with back positive coil through line position, and the output end for returning the input terminal D/A converter of positive coil is connected, when
When completing the searching of a coordinate position, magnetic conductance ball influences rotation next time, adds back just not in the position of initial coordinate
After coil, top core is turned to initial position by D/A converter, and then the positive coil that returns of vertical direction is powered, due to
Magnetic fields, magnetic conductance ball are aligned back with iron core just automatically, and time positive principle in another direction is identical;3, mainboard expands equipped with USB
Slot is opened up, reservoir can directly be accessed by usb expansion slot, internal offline map data and other data are updated, to guarantee
The accuracy of search effect;4, the top before cabinet is provided with loudspeaker, and loudspeaker is connected with the D/A converter on mainboard,
After user says the geographical location keyword wanted to look up, multiple alternate items are provided after processor identifies, pass through loudspeaking
Device voice broadcast, for user's second selecting, keeps search result more accurate to user, while reservoir memory is placed with key
The profile information in geographical location, after search, loudspeaker can play the introduction in the place being stored in reservoir, and allowing makes
User recognizes the information in more places, improves children's study efficiency, excites children's study interest.
