Because the mobile phone 110 and the mobile phone 120 are two independent links for communication and music and conversation audio are respectively played in a sound zone, the conversation and the music are independent and not interfered, and the entertainment experience is improved.
First, a method for paralleling a phone and music based on a bluetooth module of a vehicle machine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
The phone and music parallel method based on the vehicle-mounted Bluetooth module is applied to a system formed by a vehicle-mounted device, first electronic equipment and second electronic equipment, wherein the vehicle-mounted device is respectively connected with a first audio module of a public audio zone and a second audio module of a private audio zone.
Fig. 2 is a flowchart of a phone and music parallel method based on a bluetooth module of a vehicle.
As shown in fig. 2, according to a flowchart of a phone and music parallel method based on a bluetooth module of a vehicle, the flowchart includes S100-S300, and several steps are described in detail below:
s100, the vehicle machine is independently connected with the first electronic device and the second electronic device through the Bluetooth module.
Specifically, the car machine may establish a music service link with the first electronic device on an ACL (Asynchronous connection) link, for example, an A2DP (Advanced Audio Distribution Profile) connection may be established; and establishing a telephony service connection with the second electronic device over the ACL link, for example, HFP (handles-free Profile) connection may be established.
More specifically, the ACL link is a packet data transmission link, which supports both one-to-one data transmission and one-to-many data transmission, that is, the vehicle device can establish a data transmission channel with the first electronic device and the second electronic device through the ACL link. Therefore, data transmission channels can be respectively established with the two mobile phones to transmit the audio data of conversation and music.
S200, the audio played by the first electronic equipment is played through the first audio module of the public audio zone.
S300, when the second electronic device dials or accesses the telephone, the car machine plays the audio communicated with the second electronic device through the second audio module, and keeps the audio played by the first electronic device to be played through the first audio module. Therefore, the communication of the second electronic equipment and the music played by the first electronic equipment are independent from each other and are not interfered, and the entertainment experience is improved. This process will be described in detail below.
In an embodiment of the present invention, the public range of the vehicle may include one or more of a main driving range 101, a sub-driving range 102, and a rear row range 103. The private sound zone may include a main driving sound zone 104.

The main driving area 101 is located at a main driving seat door, the auxiliary driving area 102 is located at an auxiliary driving seat door, the rear exhaust area 103 is located at two side doors of a rear seat of the vehicle, the private area 104 is located at the main driving seat door or seat, and the private area 104 can be used, for example, a headrest or an earphone is arranged at the main driving seat, so that the privacy of the call can be ensured.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for phone and music parallel based on bluetooth of the vehicle, including:
the audio played by the first electronic device is played through the first audio module, for example, when the first electronic device plays music, the vehicle machine applies for opening a Bluetooth music channel; and the first electronic equipment starts to transmit audio data and decodes the audio data into audio data according to the audio decoding mode negotiated when the first electronic equipment is connected with the car machine.
Specifically, when the first electronic device plays music, the car machine applies for opening a bluetooth music audio channel after receiving that the playing status of the first electronic device is streaming, and the first electronic device decodes the audio data into PCM (Pulse Code Modulation) audio data and writes the PCM audio data into the bluetooth music audio channel according to an audio decoding method negotiated when the first electronic device is connected to the car machine, for example, the decoding method may be one of SBC, AAC, and LDAC, and at this time, no other audio data exists in the audio channel, so that the music audio can play audio in an open audio zone.
When the second electronic equipment dials or accesses the telephone, the car machine plays the audio communicated with the second electronic equipment through the second audio module, and keeps the audio played by the first electronic equipment to be played through the first audio module.
In an embodiment of the present invention, when the second electronic device makes or accesses a call, the car device adjusts the volume played by the first audio module in the public audio zone, and performs the playback in the private audio zone after amplifying the gain of the downlink call data with the second electronic device.
For example, when the second electronic device makes or accesses a call, the car machine adjusts the first audio module of the primary driving zone to be mute, reduces the volume played by the first audio module of the secondary driving zone, and also appropriately increases or decreases the volume according to the current volume of the rear row of sound zones. The first audio module of the main driving area is adjusted to be silent, the volume played by the first audio module of the auxiliary driving area is reduced, the main driving can communicate more clearly, and the communication quality is effectively improved.
Further, the vehicle may establish a synchronous bluetooth link with the second electronic device and turn on the second audio module. Specifically, the vehicle may establish a bluetooth (SCO) link with the second electronic device, where the SCO link is a link for Synchronous voice transmission, and may transmit data with a high requirement for time, and may effectively reduce call delay and improve call quality.
Furthermore, the car machine performs gain on the downlink call data of the second electronic device and then writes the gain data into the second audio module. Specifically, after the SCO connection is established, the call audio data of the second electronic device is immediately transmitted to the second audio module through the link, and the car may perform gain amplification processing on the downlink call audio data, write the call audio data into the telephone channel of the private sound area, and output the call audio data to the private sound area.
Furthermore, the method for the parallel of the telephone and the music based on the Bluetooth module of the vehicle machine further comprises the following steps:
the car machine captures and transmits uplink call data through a microphone in the private sound area.
After the second electronic equipment finishes the call, the car machine closes the second audio module of the private sound zone and restores the volume played by the first audio module of the public sound zone.
Further, the car machine snatchs and transmits the data of going up a conversation through the microphone in private sound district, include: the car machine captures the call sound of the private zone through a microphone of the private zone; the car machine performs echo cancellation and noise reduction on the uplink call data through echo cancellation software; echo and noise are eliminated through software, so that the call quality can be ensured, and the cost can be effectively reduced because only the software is used for processing call data. And transmitting the uplink call data through the SCO link. The SCO link is a link for synchronous voice transmission, and can effectively reduce call delay and improve call quality in an uplink call process.
