Abstract
The utility model discloses a circuit for regulating a vehicle terminal volume in a double-machine interactive mode. The circuit comprises an audio input interface which is in HDMI connection with a smart mobile terminal to receive HDMI audio signals, an audio converter which converts the HDMI audio signals into analog audio signals, an audio decoder which converts the analog audio signals into digital audio signals, and a vehicle audio processor which processes the digital audio signals and controls sound output according to a volume curve of a vehicle terminal. With the adoption of the circuit, the vehicle terminal adopts the audio frequency, so that the vehicle terminal volume is set without being limited to a smart mobile terminal volume, and a user is facilitated in regulation.
Description
Technical field
The utility model relates to volume adjusting technical field, relates in particular to a kind of circuit that regulates car-mounted terminal volume under two-shipper interactive model.
Background technology
At present, the realization of the interconnected pattern of car-mounted terminal is mainly MirrorLink and customized development.MirrorLink combines by some international well-known intelligent mobile terminal manufacturers and automaker a kind of " car networking " standard of initiating foundation, is intended to effective connection of standard intelligent mobile terminal and onboard system, and forms good user's experience.Target is to make user in vehicle traveling process, need not see intelligent mobile terminal screen, touch intelligent mobile terminal screen or operative intelligence mobile terminal key, only need to control intelligent mobile terminal by the physical button on vehicle-mounted or voice command, comprise answer/make phone, listen intelligent mobile terminal music, with intelligent mobile terminal, navigate etc.
But, service condition for intelligent mobile terminal volume, especially intelligent mobile terminal turning down sound volume or heighten under state, can cause user to regulate car-mounted terminal volume not reach perfect condition at car-mounted terminal, such as: the intelligent mobile terminal volume minimum in the situation that, regulate the car-mounted terminal volume may be also relatively little.To user, cause puzzlement thus, affect user and experience.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of circuit that regulates car-mounted terminal volume under two-shipper interactive model is provided, and can make car-mounted terminal volume not be limited to the setting of intelligent mobile terminal volume at the adaptive audio frequency of car-mounted terminal, facilitates user to regulate.
For solving above technical problem, the utility model embodiment provides a kind of circuit that regulates car-mounted terminal volume under two-shipper interactive model, comprising:
For setting up HDMI with intelligent mobile terminal, be connected, to receive the audio input interface of HDMI audio signal;
For described HDMI audio signal being converted to the audio converter of simulated audio signal;
For described simulated audio signal being converted to the audio codec of digital audio and video signals; And,
For described digital audio and video signals is processed, according to the volume curve controlled of car-mounted terminal, control the onboard audio processor of voice output;
Wherein, the input of described audio input interface and described audio converter is connected, and the output of described audio converter is connected with the input of described audio codec, and the output of described audio codec is connected with described onboard audio processor.
Wherein, described audio codec comprises that model is the chip of WM8758; Described onboard audio processor comprises that model is the chip of TDA7419.
The utility model embodiment provides regulates the circuit of car-mounted terminal volume under two-shipper interactive model, there is following beneficial effect: use HDMI, intelligent mobile terminal audio signal transmission is arrived to car-mounted terminal, after car-mounted terminal is by car-mounted terminal audio converter output simulated audio signal, pass through again audio codec and onboard audio processor, according to the volume curve of car-mounted terminal, control the output of sound, and be not limited to the current volume value of intelligent mobile terminal, thereby the audio frequency power amplifier scope of having unified mobile unit, facilitates user to regulate.Simultaneously, regulating car-mounted terminal volume is also to complete control by car-mounted terminal, can't return the volume setting of control intelligent mobile terminal self, when user is after car-mounted terminal pulls out intelligent mobile terminal, volume value before intelligent mobile terminal can remain on and connect, so user can be because of having used after the interconnected mobile unit of two-shipper, and to go repeatedly to regulate intelligent mobile terminal volume, promote user's experience, and strengthened traffic safety.
