Vehicle-mounted CD player interface, vehicle-mounted CD player, electrical connection structure and communication method of vehicle-mounted mp5 and vehicle-mounted CD player

Abstract

The invention discloses a vehicle-mounted CD player interface. The vehicle-mounted CD player interface comprises a single-chip microcomputer, a serial conversion module and an operational amplification module, wherein the single-chip microcomputer is used for converting a communication protocol of a CD player core into a standard communication protocol and converting the standard communication protocol into the communication protocol supported by the CD player core, and the single-chip microcomputer is connected with the CD player core; the serial conversion module is used for converting the standard communication protocol into a serial communication protocol and converting the serial communication protocol into the standard communication protocol, and the serial conversion module is connected with the single-chip microcomputer and a vehicle-mounted MP5; and the operational amplification module is used for amplifying an audio output by the CD player core and transmitting the amplified audio to the vehicle-mounted MP5, and the operational amplification module is connected with the vehicle-mounted MP5 and the CD player core. The invention furthermore discloses a vehicle-mounted CD player, and an electric connection structure and a communication method of the vehicle-mounted MP5 and the vehicle-mounted CD player. According to the vehicle-mounted CD player interface, the vehicle-mounted CD player, and the electric connection structure and the communication method of the vehicle-mounted MP5 and the vehicle-mounted CD player, different types of vehicle-mounted CD players can communicate with the same vehicle-mounted MP5, so that the universality of the vehicle-mounted MP5 is improved.

Description

technical field [0001] The invention belongs to automobile electrical equipment, in particular to a vehicle-mounted CD machine interface, a vehicle-mounted CD machine, an electrical connection structure and a communication method between a vehicle-mounted MP5 and the vehicle-mounted CD machine. Background technique [0002] More and more in-vehicle entertainment systems in cars adopt a split structure. For example, for the same model, high configuration requires on-board MP5 plus CD movement, while low configuration only requires on-board MP5. In order to meet this demand and reduce repeated development, usually Take the way of car MP5 and car CD player. In order to achieve the same model share the same car MP5, such as figure 1 shown. [0003] However, with the continuous development and non-standardization of the CD movement industry, it is necessary to develop different vehicle-mounted MP5s simultaneously for vehicle-mounted CD players that use different CD movements, a...

Problems solved by technology

[0003] However, with the continuous development and non-standardization of the CD movement industry, it is necessary to develop different vehicle-mounted MP5s simultaneously for vehicle-mounted CD players that use different CD movements, and MP5 cannot be universalized. figure 2 As shown, the design cost is increased, and there are many product models, which is not conducive to inventory management
