All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The most widely used bluetooth technology in daily life is in bluetooth-enabled mobile phone call devices, such as bluetooth headsets of mobile phones, vehicle-mounted hands-free bluetooth, and the like. The Bluetooth technology in the vehicle-mounted Bluetooth system is continued from the Bluetooth technology of a mobile phone and has the same transmitting system; bluetooth technology makes driving safer.
Most of automobiles on the market at present only support to play car multimedia audio and Bluetooth music or answer a vehicle-mounted Bluetooth telephone through a full-car loudspeaker, so that other passengers in the car can be disturbed to have a rest, and other passengers can not listen to other audio.
The vehicle-mounted wireless Bluetooth headset is also one of the wireless Bluetooth headsets, can provide different sound zone services for a vehicle-mounted system together with vehicle-mounted playing equipment (such as a vehicle-mounted sound box), and can meet the audio playing requirements of drivers and passengers. Based on the above, the invention provides a method for switching multimedia sound zones in a vehicle, so as to achieve the purpose that the playing of each sound zone is not interfered with each other. The method comprises the following steps:
and 110, establishing connection with a Bluetooth playing device, establishing an audio playing channel of the Bluetooth playing device and being independent of an audio playing channel of a vehicle-mounted playing device, wherein the Bluetooth playing device is used for independently playing multimedia audio of a vehicle machine.

For example, when a bluetooth phone is accessed, the bluetooth device is used for playing by default, and certainly, the bluetooth device can be actively switched to a vehicle-mounted playing device by a user for playing.
In another embodiment, a car machine system (or called car machine) configures an audio playing channel of the bluetooth playing device or the vehicle-mounted playing device according to the validity of the occupancy signals of the main driving screen, the assistant driving screen and the assistant driving seat. The car machine system automatically selects a playing device of a playing sound zone of the audio according to the seat occupancy signal in the car; when the multimedia audio is played on the auxiliary driving screen and the occupation signal of the auxiliary driving seat is invalid, the vehicle-mounted system selects the channel of the vehicle-mounted loudspeaker to play the audio in a default mode. The method comprises the steps that when a multimedia application is played on a secondary driving screen and a secondary driving seat occupation signal is effective, an audio playing channel of the Bluetooth playing device is configured to play multimedia audio, and when a multimedia application is played on a main driving screen and the secondary driving seat occupation signal is ineffective, an audio playing channel of the vehicle-mounted playing device is configured to play multimedia audio, wherein the vehicle-mounted playing device comprises a vehicle-mounted loudspeaker.
In the above embodiment, the execution time range can be set as a time period of one vehicle running cycle, i.e. a period of use between startup and shutdown or between startup and shutdown of the on-board multimedia system. For example, multimedia audio which is firstly opened and played in a car using period, the car machine system automatically selects a playing sound zone of the audio according to the seat occupying signal in the car, and determines corresponding playing equipment. And in the same vehicle using period, if the multimedia application is not started and played for the first time, selecting the audio playing channel configured in the previous using period to play the multimedia audio.
