Description

A kind of Baffle Box of Bluetooth based on the NFC technology
Technical field
The utility model relates to based on the near-field communication technology technical field of bluetooth communication of (being called for short NFC, Near Field Communication), relates in particular to a kind of Baffle Box of Bluetooth based on the NFC technology.
Background technology
Bluetooth is the radiotechnics of a kind of support equipment short haul connection (in general 10 meters), can comprise that carrying out wireless messages between numerous equipment such as mobile phone, PDA, wireless headset, notebook computer and relevant peripheral hardware exchanges.Utilize Bluetooth technology can effectively simplify communication between the mobile communication terminal device, make people cast aside the constraint of traditional line, enjoy unfettered enjoyment.Along with developing rapidly of Bluetooth technology, the blue tooth products application is increasingly extensive, as bluetooth earphone, Baffle Box of Bluetooth etc.
Yet, day by day universal along with handheld device (mobile phone, panel computer), when these end products used Bluetooth audio frequencies transmission, need to carry out first the Bluetooth pairing operation, and Baffle Box of Bluetooth often following problem can occur: (1) Baffle Box of Bluetooth pairing speed was slow; (2) must have and will two bluetooth equipments be entered the pairing state simultaneously through button operation owing to finishing the Bluetooth pairing function, therefore operation is not very convenient.
Summary of the invention
The purpose of this utility model is to provide a kind of Baffle Box of Bluetooth based on the NFC technology for the above-mentioned deficiency of existing Baffle Box of Bluetooth.
In order to achieve the above object, the utility model has adopted following technical scheme:
A kind of Baffle Box of Bluetooth based on the NFC technology comprises the blue teeth wireless receiver, connects change-over circuit, NFC module, power electronic switch circuit, audio power amplifier circuit, audio interface circuit, loud speaker and power-supply circuit; Power-supply circuit is electrically connected to the power electronic switch circuit, the NFC module is electrically connected to blue teeth wireless receiver and power electronic switch circuit, and blue teeth wireless receiver, connection change-over circuit, audio power amplifier circuit, audio interface circuit and loud speaker are electrically connected successively.
Wherein, the power supply supply provides electric power for whole circuit, the power electronic switch circuit is controlled whole circuit, the NFC module is used for the switch with the power electronic switch circuit of waking up of control blue teeth wireless receiver, the blue teeth wireless receiver is used for the receiving terminal apparatus Bluetooth audio signals, connect the matching connection that change-over circuit is used for realizing audio power amplifier circuit and Bluetooth audio signals, audio power amplifier circuit is connected for audio frequency power amplifier and with loud speaker, by loud speaker original sound also.
The utility model discloses a kind of Baffle Box of Bluetooth based on the NFC technology.By NFC technology and Bluetooth technology are combined, realized quick pairing, the disconnection of Baffle Box of Bluetooth and other terminal equipment and be connected, greatly improved the convenience of user's operation.
Description of drawings
Fig. 1 is the Baffle Box of Bluetooth principle schematic;
Fig. 2 is Baffle Box of Bluetooth work schematic diagram;
Number in the figure: blue teeth wireless receiver 1 connects change-over circuit 2, audio power amplifier circuit 3, audio interface circuit 4, loud speaker 5, NFC module 6, power electronic switch circuit 7, power-supply circuit 8.
Embodiment
Below in conjunction with specific embodiment the technical solution of the utility model is done further clearly and completely explanation.
Embodiment
Embodiment discloses a kind of Baffle Box of Bluetooth based on the NFC technology.In conjunction with Fig. 1 and Fig. 2, this Baffle Box of Bluetooth comprises blue teeth wireless receiver 1, connects change-over circuit 2, NFC module 6, power electronic switch circuit 7, audio power amplifier circuit 3, audio interface circuit 4, loud speaker 5 and power-supply circuit 8; Power-supply circuit 8 is electrically connected to power electronic switch circuit 7, NFC module 6 is electrically connected to blue teeth wireless receiver 1 and power electronic switch circuit 7, and blue teeth wireless receiver 1, connection change-over circuit 2, audio power amplifier circuit 3, audio interface circuit 4 and loud speaker 5 are electrically connected successively.
The concrete course of work is: when the terminal equipment of opening bluetooth during near the Baffle Box of Bluetooth of opened bluetooth, terminal equipment directly obtains the Bluetooth chip address of audio amplifier and is transferred to its inner bluetooth module from audio amplifier NFC module 6, enter the Bluetooth pairing state, simultaneously, the NFC module 6 of audio amplifier is waken the blue teeth wireless receiver 1 in the audio amplifier up, realizes the Bluetooth pairing between terminal equipment and audio amplifier; And then by bluetooth audio reception information, and pass through the matching connection that connection change-over circuit 2 is realized audio power amplifier circuits 3 and Bluetooth audio signals, and be connected by audio power amplifier circuit 3 realization audio frequency power amplifiers and with loud speaker 5 again, finally go back original sound by loud speaker 5.
The utility model is by combining NFC technology and Bluetooth technology, realized quick pairing, the disconnection of Baffle Box of Bluetooth and other terminal equipment and is connected, and greatly improved the convenience of user's operation.
More than be that better enforcement of the present utility model is specified, but the utility model is not limited to above-described embodiment, those of ordinary skill in the art make all equivalent variations or replacement also can doing under the prerequisite of the utility model spirit, the distortion that these are equal to or replace all is included in the application's claim limited range.
