The invention discloses a vehicle-mounted navigation system adopting voice control. The system comprises an audio output system and an audio input system, the audio input system comprises a main control module, and a decibel detection module A and a decibel detection module B which are electrically connected with the main control module, the decibel detection module B is arranged on the inner side of a sound inlet, the decibel detection module A is arranged on the outer side of the sound inlet, and the main control module and the decibel detection module B are separately arranged in an inner cavity of the navigation shell. When a user sends an instruction to the vehicle-mounted navigation device, through the arrangement of the decibel detection module A, the decibel detection module B and the main control module, the sound on the inner side and the outer side of the sound inlet can be accurately measured, so that the dust blocking degree of the sound inlet can be judged, the power-on and power-off of an electromagnet can be controlled, and the sound inlet can be cleaned by using a brush.

    本发明公开了一种采用语音控制的车载导航系统,包括音频输出系统和音频输入系统,音频输入系统包括主控模块和与主控模块之前进行电性连接的分贝检测模块A和分贝检测模块B,分贝检测模块B设置在进声口的内侧处,分贝检测模块A设置在进声口的外侧处,主控模块和分贝检测模块B都分别设置在导航外壳的内腔中,当使用者对车载导航发出指令时,通过分贝检测模块A、分贝检测模块B和主控模块的设置,使得车载导航可以对位于进声口内外侧的声音进行准确的测量,从而可以判断出进声口被灰尘堵塞的程度,以此来控制电磁铁的通电断电,从而可以实现使用毛刷对进声口进行清理。
