Detailed Description

The present invention will be described with reference to the accompanying drawings.

As shown in fig. 1, the theoretical model of the present invention has the following functions: the wired sound source 1 is in butt joint with a port 11 of a pluggable earphone cable with an MMCX (millimeter-wavelength digital) public seat port and a microphone, and is transmitted to the loudspeaker unit 18 through an MMXC (multimedia center-of-care) interface so as to achieve the purpose of wired power amplification; and a second function: the wireless sound source 2 is in signal butt joint with the Bluetooth IC module 19 to transmit the Bluetooth sound source to the loudspeaker unit 18, so that the purpose of wireless power amplification is achieved. The utility model discloses two main functions of bluetooth and wired audio transmission have.

In the specific circuit schematic diagram of the present invention shown in fig. 2, the circuit of the left bluetooth headset 14 includes a microphone MIC3, a left bluetooth IC module 4, a battery BATT 6, a battery switch POWER7, a bluetooth indicator light BT LED8, and an MMCX female socket port 9; meanwhile, the circuit of the right bluetooth headset 15 comprises a microphone MIC3, a right bluetooth IC module 5, a storage battery BATT 6, a battery switch POWER7, a bluetooth indicator light BT LED8 and an MMCX female socket port 9. The utility model discloses a control bluetooth headset all can the exclusive use, all have switch bluetooth function, all have the female seat port of MMCX, all can with take the public seat port of MMCX to contain pulling out of microphone and insert earphone cord 11 and dock.

The utility model discloses the special design of circuit designs out parallelly connected shunt circuit between left sound track signal output part LSPK12 and left bluetooth IC module 4, and these two shunt circuits LSPK + correspond with the positive negative pole of the female seat port 9 of MMCX respectively with LSPS-and is connected. Similarly, a shunt circuit connected in parallel is designed between the right sound channel signal output end RSPK13 and the right bluetooth IC module 5, and the two shunt circuits RSPK + and RSPS-are respectively connected with the positive electrode and the negative electrode of the MMCX female socket port 9. When the battery switch POWER7 is in the off state and the MMCX female socket port 9 in the bluetooth headset is not in butt joint with the MMCX male socket port 10 on the pluggable headset line, the parallel shunt circuit is open, no current passes through, and no influence is generated on the opening and closing of the bluetooth module circuit. Simultaneously, the user begins to use wired audio frequency function, with the female seat port of MMCX 9 in the bluetooth headset with can pull out the public seat port of MMCX 10 butt joint on the earphone cord, because the unicity of function selection, bluetooth module will be in the off-state this moment always, avoids the signal conflict. When battery switch POWER7 opened, bluetooth pilot lamp BT LED8 lights, began to use bluetooth POWER amplifier function this moment, and the disconnection of female seat port 9 of MMCX and public seat port 10 of MMCX is kept at this moment, and bluetooth function can normal use. This novel circuit design has solved bluetooth and has combined integrative bluetooth area line and can pull out plug-in earphone design with wired audio transmission.

It is shown in fig. 3 a bluetooth area line can pull out the structural schematic diagram of an embodiment one of inserting formula earphone, the mode that straight plug 16 of taking the public seat port of MMCX meets with the female seat port 9 of bluetooth earphone MMCX, the utility model discloses be called it and cut straightly formula. Take public seat port of MMCX to contain pluggable earphone cord of microphone have the public seat port of formula MMCX of cuting straightly, can cut straightly in the female seat of MMCX, take public seat port of MMCX to hold the other end of pluggable earphone cord of microphone and be connected with audio plug.

It is shown in fig. 4 a bluetooth area line can pull out the structural schematic diagram of an embodiment one of inserting formula earphone, the mode that curved plug 17 of taking the public seat port of MMCX meets with the female seat port 9 of bluetooth earphone MMCX, the utility model discloses be called curved formula of inserting with it. Take public seat port of MMCX to contain pluggable earphone cord of microphone have the public seat port of curved formula MMCX of inserting, can bend insert in the female seat of MMCX, take the public seat end of MMCX to hold the other end of pluggable earphone cord of microphone and be connected with audio plug.

The utility model discloses an solve traditional bluetooth headset and combined wired earphone function in circuit design of an organic whole, about the adoption sound channel signal output positive negative pole circuit respectively with the bluetooth IC module that corresponds between shunt circuit, make the circuit positive negative pole correspondence of shunting connect on the positive negative pole of the female seat of MMCX to bluetooth headset all possesses the function of the external earphone cord of taking the public seat port of MMCX about reaching. The utility model has the advantages that the user can detach the pluggable earphone cord and open the Bluetooth function to carry out the wireless earphone mode according to the requirement when needing to use the wireless earphone; if the wired earphone is needed, the power supply of the Bluetooth earphone is turned off, and the pluggable earphone is connected, so that the wired earphone mode can be converted. And simultaneously, the utility model provides a control bluetooth headset's female seat of MMCX and take public seat port of MMCX and can pull out between the plug-in earphone cord and insert two kinds of modes with the bend. The utility model discloses a low in manufacturing cost, circuit design are simple reasonable, the function is many and convenient to use.
