Vehicle-mounted navigation system adopting voice control

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, in particular to a vehicle navigation system using voice control. Background technique [0002] Car navigation is carried out by using car GPS (Global Positioning System) with electronic map. It can tell the driver the shortest or fastest route to the destination conveniently and accurately. It is a good helper for the driver. However, for the convenience of driving Drivers can operate the car navigation function without transferring their eyesight to the car navigation when driving. Generally, the voice control function is set on the car navigation. This setting allows the user to directly perform functions on the car navigation by speaking. Controls and adjustments for easy access. [0003] The current car navigation voice control sound inlet hole is usually blocked due to long-term dust and untimely cleaning. In this case, when the user performs voice input, the car navigation cann...

Problems solved by technology

[0005] The purpose of the present invention is to provide a vehicle navigation system using voice control, which works by using this device, thereby solving the problem of sound inlet holes in vehicle navigation voice control in the above background, which are usually caused by long-term ash falling and untimely cleaning. In this case, when the user performs voice input, the car navigation cannot accurately and quickly recognize it, which is inconvenient for the user. The brush tool is cleaned from the outside. This method not only takes time to find tools, but also consumes manpower to clean the sound inlet. At the same time, it is easy to clean the sound inlet no matter whether it is cleaned by blowing from the outside or cleaning from the outside with a brush. The dust on the sound port is cleaned into the inside of the device, and the dust inside the device will cause various problems over time, which is not easy to use
