Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings and in conjunction with the embodiments.

[0017] refer to figure 1 , the virtual bluetooth system of the present invention is established between the smart phone and the vehicle-mounted terminal, wherein the vehicle-mounted terminal has a voice receiving module, a voice processing module and a data transmission module. The smart phone and the vehicle-mounted terminal communicate and connect through the data transmission module, and the data transmission module transmits through the real-time transmission protocol. Specifically, it can be a WIFI module or a USB interface module other than the Bluetooth module. When the WIFI module is used, the two are connected wirelessly, and when the USB interface module is used, it is only necessary to connect the two through a USB data cable.

[0018] The voice receiving module of the vehicle terminal is generally an external MIC, whic...

Abstract

The invention discloses a vehicle-mounted terminal and smart phone interconnection and interaction virtual Bluetooth system which comprises a smart phone and a vehicle-mounted terminal with a voice receiving module, a voice processing module and a data transmission module. The vehicle-mounted terminal is in communication connection with the smart phone through the data transmission module. When the smart phone needs calling, the vehicle-mounted terminal receives voice information through the voice receiving module, and the voice information after being processed through the voice processing module is transmitted to the smart phone in realtime by utilizing the data transmission module. The voice information is received through the vehicle-mounted terminal and transmitted to the smart phone when the smart phone calls, so that a virtual Bluetooth function is realized; the smart phone can be matched with the vehicle-mounted terminal to realize a hands-free calling function, so that traveling safety is guaranteed, the problem of same-frequency interference when WIFI and Bluetooth are used at the same time is avoided effectively, calling quality is improved, and higher practicability and better user experience are realized.

Description

technical field [0001] The invention relates to signal processing technology, in particular to the technical field of smart phone signal processing. Background technique [0002] With the increasing popularity of smartphones and cars, people spend more and more time using their mobile phones in the car. According to statistics, at present people spend more than 20 hours in the car on average a week, therefore, the car compartment is one of the main occasions for people to use mobile phones. [0003] In order to ensure driving safety, drivers generally use bluetooth devices to make calls when driving. However, since the vehicle is generally equipped with WIFI equipment, when Bluetooth and WIFI are used at the same time, co-channel interference will occur, which will have a greater impact on the quality of the call, and the practicability and user experience will be poor. Contents of the invention [0004] In view of the above problems, the present invention provides a vir...
