Abstract
The invention discloses a Bluetooth loudspeaker box control circuit which comprises a USB input circuit (1), a lithium ion power supply circuit (2), an amplifier power supply circuit (3), a microphone input circuit (4), an external sound source input circuit (5), a Bluetooth module (6), a button and LED circuit (7), a single-chip microcomputer control circuit (8) and an amplifier circuit (9). The USB input circuit (1) directly powers the lithium ion battery in the lithium ion power supply circuit (2). The output of the lithium ion power supply circuit (2) is divided into two parts, one part enters the amplifier power supply circuit (3) and is transformed into 5V/1.5A and then directly powers the amplifier circuit (9), and the other part directly powers the single-chip microcomputer control circuit (8).
Description
Technical field
The present invention relates to a kind of control circuit, relate to a kind of software and hardware combining Baffle Box of Bluetooth control circuit further.
Background technology
Electronic technology develop rapidly, consumer is perfect day by day to the pursuit of audio amplifier, while having enjoyed sound, reduce circuit link as far as possible, install and easy to carry etc. be all the problem that manufacturer will face, Bluetooth technology is arisen at the historic moment under this specific historical conditions.Baffle Box of Bluetooth refers to embedded with bluetooth chip, connects the stereo set replacing traditional wire rod and connect with bluetooth, by being connected with the bluetooth playback equipment such as mobile phone, panel computer and notebook, reaches conveniently object.Common Baffle Box of Bluetooth mostly is monophony and tradition 2.0 output audio amplifier on the market, but does not all have superpower third dimension.
Meanwhile, and due to the restriction of control circuit software and hardware, make traditional Baffle Box of Bluetooth audio amplifier cannot be carried out fractionation and use, thus shone into great inconvenience to user.
Summary of the invention
In view of above content, be necessary to provide one to have high tone quality simultaneously, and the Baffle Box of Bluetooth control system that the audio amplifier of script 2.0 arbitrarily can be combinationally used.
The invention provides a kind of software and hardware combining Baffle Box of Bluetooth control circuit, comprising:
USB input circuit (1), lithium battery power supply circuit (2), amplifier power supply circuits (3), microphone input circuit (4), external sound source input circuit (5), bluetooth module (6), button and LED circuit (7), single chip machine controlling circuit (8), and amplifier circuit (9), described USB input circuit (1) is powered directly to the lithium battery in lithium battery power supply circuit (2), and lithium battery power supply circuit (2) is divided into two parts to export, a part enter amplifier power supply circuits (3) afterwards transformation be after 5V/1.5A, power directly to amplifier circuit (9), another part is powered directly to single chip machine controlling circuit (8).
Further, preferably, the source of sound that described microphone input circuit (4), external sound source input circuit (5) and mobile phone mobile device are undertaken by bluetooth module (6) is directly inputted in single chip machine controlling circuit (8), is defeated by amplifier circuit (9) plays by single chip machine controlling circuit (8) after being processed.
Further, preferably, described button and LED lamp circuit (7) directly and single chip machine controlling circuit (8) carry out mutual handshaking.
Further, preferably, the single-chip microcomputer of described single chip machine controlling circuit (8) is commercially available IDS-BM5A.
Compared with prior art, the invention has the advantages that:
(1) when be connected with mobile phone or miscellaneous equipment again after two audio amplifiers connect use time, two audio amplifiers can identify left and right automatically, sound channel is separated into automatically two independent audio amplifiers, reach the effect of 2.0 traditional stereo speakers, because this audio amplifier is wireless connections, two audio amplifiers can select different local placement to use (in coverage 10 meters), experience the acoustics that different sound fields is brought;
(2) this audio amplifier also can be used alone, and exports left and right acoustic channels is merged into a sound channel output automatically when being used alone, and prevents part music from losing.
Accompanying drawing explanation
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the circuit theory diagrams of Baffle Box of Bluetooth control circuit of the present invention;
Fig. 2 is the flow chart of the soft Baffle Box of Bluetooth control circuit of the present invention.
Embodiment
Shown in Fig. 1, described Baffle Box of Bluetooth control circuit, comprises USB input circuit 1, lithium battery power supply circuit 2, amplifier power supply circuits 3, microphone input circuit 4, external sound source input circuit 5, bluetooth module 6, button and LED circuit 7, single chip machine controlling circuit 8, and amplifier circuit 9;
Wherein USB input circuit can be powered directly to the lithium battery in lithium battery power supply circuit 2.Lithium battery power supply circuit 2 is divided into two parts to export, and it is power directly to amplifier circuit 9 after 5V/1.5A that a part enters the rear transformation of amplifier power supply circuits 3.Lithium battery power supply circuit 2 is powered directly to single chip machine controlling circuit 8.
Simultaneously by microphone input circuit 4, the mobile devices such as external sound source input circuit 5 and mobile phone are directly inputted in single chip machine controlling circuit 8 by the source of sound that bluetooth module 6 carries out, and be defeated by amplifier circuit 9 play by single chip machine controlling circuit 8 after being processed.
Direct and single chip machine controlling circuit 8 are carried out mutual handshaking by button and LED lamp circuit.
Wherein, corresponding software section is then in the single-chip microcomputer IDS-BM5A of burning in single chip machine controlling circuit 8, and software program portion comprises main program, UI program, button program, and AUTH connects and INQUIRY polling routine, AVRCP program, A2DP program and HFP program.
Wherein software program portion as shown in Figure 2, when after opening power, automatically enters Main main program, can carry out SM initialization afterwards, can automatically enter UI program and enter Button button program after initialization completes.Afterwards, can carry out AUTH and connect and INQUIRY polling routine, whether the audio amplifier whether inquire about has another one to match exists and has source of sound to input, if exist, then enters A2DP program and HFP program.If no, then enter AVRCP program thus turn back to the Button button program phase.
Compared with prior art, the invention has the advantages that:
(1) when be connected with mobile phone or miscellaneous equipment again after two audio amplifiers connect use time, two audio amplifiers can identify left and right automatically, sound channel is separated into automatically two independent audio amplifiers, reach the effect of 2.0 traditional stereo speakers, because this audio amplifier is wireless connections, two audio amplifiers can select different local placement to use (in coverage 10 meters), experience the acoustics that different sound fields is brought;
(2) this audio amplifier also can be used alone, and exports left and right acoustic channels is merged into a sound channel output automatically when being used alone, and prevents part music from losing.
The improvement that the present invention carries out mainly for Baffle Box of Bluetooth control circuit, the foregoing is only present pre-ferred embodiments, non-ly therefore namely limit to the scope of the claims of the present invention, therefore the simple and easy change of such as doing by specification of the present invention and graphic content and equivalent transformation, all should be contained in the scope of the claims of the present invention.
