Abstract
The utility model relates to the technical field of cigar lighters used in vehicles, in particular to a cigar lighter with a built-in command decoder and an FM emitter. The cigar lighter with the built-in command decoder and the FM emitter solves the technical problems that the function of an existing cigar lighter is single, signals are prone to being interfered, and the existing cigar lighter is inconvenient to operate and use. The cigar lighter comprises a cigar lighter shell body, and a power supply conversion module and an FM radio frequency modulator module are arranged in the cigar lighter shell body. The cigar lighter is characterized in that the FM radio frequency modulator module is connected with an audio input interface, and a double-audio DTMF receiving module connected with the audio input interface and an MCU control module connected with the double-audio DTMF receiving module are further arranged on the cigar lighter shell body. The MCU control module is connected with and controls the FM radio frequency modulator. Audio signals can be transmitted to the cigar lighter through an audio interface, commands operating and controlling an FM emitter controller can be generated on a smart phone through client software, the operation and control of the FM emitter controller can be achieved, and the cigar lighter with the built-in command decoder and the FM emitter is convenient to use and low in cost.
Description
Technical field
The utility model relates to the Cigarette lighter technical field of using on vehicle.
Background technology
The existing Cigarette lighter that automobile power source is power electronic equipment that obtains that is used for being inserted into the automobile power source interface, function singleness is mainly used in being power electronic equipment; Although occur on the market the Cigarette lighter with MP3 and FM projector, by going being transferred in auto audio equipment by FM projector wireless transmission after the sound signal modulation, but because the Cigarette lighter volume is little, supply the action button setting on Cigarette lighter or without the space, the changeless frequency emission that the FM projector adopts, the deficiency of existence is: the signal of FM projector emission is disturbed by the signal of other FM projector emission of same frequency easily; Be to set up relatively undersized read-out and button on Cigarette lighter, the deficiency of existence is: increase hardware cost, and read-out and button less, inconvenience is used in operation.
Summary of the invention
The purpose of this utility model is to solve existing Cigarette lighter and has function singleness in sum, and signal easily is disturbed, and operates awkward technical deficiency, and a kind of built-in command demoder that proposes reaches the Cigarette lighter with the FM projector.
The technical matters that proposes for solving the utility model, the technical scheme of employing is: the built-in command demoder reaches the Cigarette lighter with the FM projector, includes a Cigarette lighter housing, is provided with power transfer module and FM radio-frequency modulator module in the Cigarette lighter housing; It is characterized in that: described FM radio-frequency modulator is connected with audio input interface, also is provided with the dual-audio DTMF receiver module that connects described audio input interface on described Cigarette lighter housing, and the MCU control module that connects dual-audio DTMF receiver module; Described MCU control module connects controls the FM radio-frequency modulator.
Described audio input interface is 3.5 millimeters COBBAIFs.
Described Cigarette lighter housing is provided with and connects the USB charging inlet that described power transfer module is mobile phone or digital product charging.
It is the dtmf signal receipt decoding chip of HT9170 that described dual-audio DTMF receiver module adopts model.
the beneficial effects of the utility model are: along with the maturation development of smart mobile phone, after downloading and installing supporting client software on smart mobile phone, connect the utility model by the audio frequency on smart mobile phone, not only can be by the COBBAIF transmit audio signals to the utility model, can also control the order of FM projector controller by the client software generating run on smart mobile phone, be sent in FM projector controller of the present utility model through COBBAIF, realize the operation control of FM projector controller, as: the adjusting operation of transmitting frequency, the preservation operation of the transmitting frequency of setting and preserve frequency transfer operation etc., easy to use, cost is low.
Description of drawings
Fig. 1 is block diagram of the present utility model.
Fig. 2 is circuit structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model, structure of the present utility model is further described.
Shown in seeing figures.1.and.2, the utility model includes a Cigarette lighter housing, is provided with power transfer module, dual-audio DTMF receiver module, MCU control module and FM radio-frequency modulator in the Cigarette lighter housing.
The FM radio-frequency modulator, be connected with audio input interface and be the COBBAIF of 3.5 millimeters, plug by the direct earphone interface with common smart mobile phone of COBBAIF, be used in the mode of broadcasting, the sound signal of COBBAIF input being launched to hoot device wirelessly; In the present embodiment, FM radio-frequency modulator module mainly adopts a model to be: the FM transmitting chip U4 of QN8007.
It is other each module for power supply that power transfer module is mainly used in obtaining power supply from the automobile power source interface, changes out simultaneously to be the power supply output of the power supply of the electronic products such as mobile phone, navigating instrument, panel computer and charging; In order to facilitate the connection of electronic product, described Cigarette lighter housing is provided with and connects the USB charging inlet that described power transfer module is mobile phone or digital product charging.
Dual-audio DTMF receiver module, adopting model is the dtmf signal receipt decoding chip U3 of HT9170, connect described audio input interface and MCU control module, be used for converting the dtmf signal that audio input interface is inputted to 4 binary-coded decimal digital signals and export to the MCU control module.
The MCU control module is used for converting 4 binary-coded decimal digital signals of dual-audio DTMF receiver module input to FM radio-frequency modulator module is operated control control signal, connects and controls FM radio-frequency modulator module.Such as: preserve and preserve the operations such as transferring of frequency by the adjustment of controlling transmitting frequency at the hand hands-operation, the transmitting frequency of setting.
