The operation sense organ of human pilot, sound when reducing vehicle traveling are the problems that vehicular manufacturer needs to solve, and presently, there are one
Kind active noise technology for eliminating, but do not apply in automotive field, and current vehicle mounted guidance（Referred to as vehicle-mounted DA）The collection in field
Middle function is very powerful, but the sound during operation of uncontrollable vehicle.Therefore, solve the problems, such as to send the sound just during vehicle traveling
It is particularly important.
Utility model content
The purpose of this utility model is to provide a kind of active noise cancellation element based on vehicle-mounted DA cross complaints system, by making an uproar
Sound collector is collected to the noise that vehicle is sent, and is converted into electric signal and is passed to central processing unit, central processing unit is to noise
Handled, make the formation of noise opposite in phase wave amplitude identical sound, played by Audio Players, noise is offset,
The sound caused by vehicle traveling is reduced, and is controlled it by vehicle mounted guidance, is easy to driver to carry out centralized Control,
Solve the problems, such as to send the sound during vehicle traveling.
The utility model provides a kind of active noise cancellation element based on vehicle-mounted DA cross complaints system, including is arranged on vehicle body
The noise collector and the vehicle mounted guidance in the middle part of vehicle body of front end, central processing unit is provided with by the vehicle mounted guidance, it is described
Audio Players are provided with by noise collector, the noise that vehicle is sent is collected by noise collector, is converted into electricity
Signal is passed to central processing unit, and central processing unit is handled noise, makes the formation of noise opposite in phase wave amplitude identical sound,
Played by Audio Players, noise is offset, electrically connected between the vehicle mounted guidance and central processing unit, by vehicle-mounted
Navigation Control central processing unit is operated.
Further improvement is that：The noise collection device lower end is provided with rotating disc, the rotating disc lower end side of being provided with
To adjusting rod.
Further improvement is that：Bluetooth connection module is provided with the central processing unit, by bluetooth connection module with
User's mobile phone is attached.
Further improvement is that：Immunity module is additionally provided with the central processing unit, passes through immunity module centering
The electric signal of central processor processing carries out anti-interference process.
The beneficial effects of the utility model：The noise that vehicle is sent is collected by noise collector, is converted into electricity
Signal is passed to central processing unit, and central processing unit is handled noise, makes the formation of noise opposite in phase wave amplitude identical sound,
Played by Audio Players, noise is offset, reduce the sound caused by vehicle traveling, and pass through vehicle mounted guidance pair
It is controlled, and is easy to driver to carry out centralized Control, improves the driving sense organ of driver, and increase by bluetooth connection module
Add control mode.
