corresponding button

9 and 10 respectively.

Described bluetooth module is installed on the Bluetooth control plate 12, and five function buttons 21 also are installed on the Bluetooth control plate 12, is respectively " to sign indicating number " button, " volume+" button, " volume-" button, " a last song " button, " next song " button.

Described base 14 offers air inlet, and the air inlet place is equipped with filter cotton lid 19 and filter cotton 18.

Fan 6, anion generation module also are installed on the described base 14, and anion generation module comprises high voltage package 5 and anion emission mouth 2, and high voltage package 5 cooperates with anion emission mouth 2.

Described filter cotton lid 19 is used to cover activated carbon filtration cotton 18, and activated carbon filtration cotton 18 is used for various impurity, the dust of filtered air.

Described supply socket 17 is a DC socket, and supply socket 17 is the external power source socket, for bluetooth module and anion module provide power supply.

A horn hood 7 is stamped in the outside of described loudspeaker 8.

Described fan 6 is a turbofan, is used for drawing through cotton 18 filtered airs of activated carbon filtration, delivers to anion emission mouth 2 places of anion generation module.

Described high voltage package 5 rises to volts up to ten thousand by transformation with supply voltage, and the output of voltage after anion emission mouth 2 will boost utilizes high tension voltage to puncture near the anion emission mouth 2 air, with near the air breakdown the anion emission mouth 2, forms anion; Fixture 3 is used for fixing whole bluetooth and anion generation module.

Described switch 16 is used to control the break-make of power supply, controls the operating state of all modules, and whole bluetooth module and anion generation module were started working when switch 16 was opened; When switch cut out, whole bluetooth module and anion generation module were not worked.

When not inserting the male of incoming line of earphone or other output equipment on the described output plughole 15, bluetooth module to output equipment loudspeaker 8, plays back the audio signal output after handling by loudspeaker 8; When the male of the incoming line that inserts earphone or other output equipment on output plughole 15, audio frequency will be from earphone or the output of other output equipment.

According to functional block diagram shown in Figure 5 and Fig. 6, circuit theory diagrams shown in Figure 7, operation principle to Bluetooth Receiver describes, wherein, code operations is realized by pressing PLAY key (to sign indicating number button 9), the PLAY key is obtained 5V voltage from power supply, the 5V power supply is by the dividing potential drop effect of R12 and R8 when the PLAY key is pressed, obtain the input voltage about 3.3V, be input to bluetooth module by PIO3, Bluetooth chip BLUETOOTH MM310 will judge the time length that button is pressed, if press for a long time, to send matched signal by the peripherad blue-tooth device of antenna, if there is device to detect this signal, by the input identification code, just can between bluetooth coalignment and Bluetooth Receiver, set up a wireless links, 2.4G channel by bluetooth specification, realize wireless data transmission, the MP3 format audio signal is handled, change into audio player and can discern the signal of processing, this signal is exported to audio player by output plughole 15, and audio signal just can play back on audio-frequence player device, when earphone connects, then output to earphone, when earphone does not connect, output to loudspeaker 8.
