Accordingly, this utility model also provides a kind of control method of headset system, specifically includes following steps：

Headset is inserted main frame 50；

Main frame 50 differentiates the classification of the headset of insertion main frame 50；

Main frame 50 is done corresponding configuration according to the classification of headset and is communicated with headset foundation, or headset differentiates insertion main frame Classification is simultaneously done corresponding configuration and is communicated with optional host-host protocol with main frame foundation.

Further, the classification of described headset includes simulating headset and digital headset 10.Main frame or headset are visited according to interface Survey result or communication result comes control main frame or the audio frequency of headset and the mode of operation of non-audio module and device.

In the present embodiment, the classification of described headset includes the digital headset of simulation headset and cardinar number word pattern or mixes standard Headset, or the classification of described main frame includes digital host or the mixing standard main frame of simulation framework and cardinar number word pattern.Described master Machine 50 set up according to the classification of headset and headset communicate including：When the classification of headset is simulation headset, work in closure main frame 50 First switch SW1 in operation mode modular converter 502, disconnects the second switch in working mode change module 502 in main frame 50 SW2, the 3rd switch SW3, the 4th switch SW4, the 5th switch SW5；When the classification of headset is digital headset 10, disconnect main frame 50 First switch SW1 in middle working mode change module 502, second in working mode change module 502 in closure main frame 50 Switch SW2, the 3rd switch SW3, the 4th switch SW4, the 5th switch SW5.

Specifically, when main frame 50 does not have headset to access, the switch in working mode change module 502 on main frame 50 SW1, SW2, SW3, SW4, SW5 all disconnect, now the wheat on the mainboard of 500 Receiving Hosts 50 of audio codec of main frame 50 Gram wind number.If have the audio interface that headset inserts main frame 50, known by the headset of the audio codec 500 of main frame 50 first Other interface is detected with the action of audio interface 40 insertion, then identifies that interface to judge the headset of access host 50 by headset Classification.

In the present embodiment, if the audio interface access of main frame 50 is simulation headset, now Working mould in closure main frame 50 First switch SW1 in formula modular converter 502, disconnects the second switch in working mode change module 502 in main frame 5050 SW2, the 3rd switch SW3, the 4th switch SW4, the 5th switch SW5, main frame 50 starts its internal driving related to simulation headset Software.Refer to Fig. 2, with audio interface 40 and headset, first switch SW1 one end identifies that the line between interface is connected, the other end Line between resistance Rc and electric capacity Cc is connected.Wherein, resistance Rc is the resistance providing biasing to simulation headset, resistance Rc One end be connected with first switch SW1, the other end is connected with the bias voltage interface of audio codec 500；Electric capacity Cc be to The input of headset provides the electric capacity of isolated DC, and one end of electric capacity Cc is connected with first switch SW1, and the other end compiles solution with audio frequency The headset access port of code device 500 is connected.

If what the audio interface of main frame 50 accessed is digital headset 10, main frame 50 starts the biasing of audio codec 500 Voltage interface, is powered to the slave modular converter 200 of headset by microphone lines MIC, and is held with traditional line traffic control protocol realization Handss communicate；Now disconnect first switch SW1 in working mode change module 502 in main frame 50, Working mould in closure main frame 50 Second switch SW2 in formula modular converter 502, the 3rd switch SW3, the 4th switch SW4, the 5th switch SW5.Now, main frame control Communicated with I2C/SPI agreement between molding block and main frame modular converter.

After audio interface 40 is extracted from the audio interface of main frame 50, (MICDET) detects This move, now main frame 50 close the configuration related to headset, for example, close first switch SW1, second switch SW2, the 3rd switch SW3, the 4th switch SW4, the 5th switch SW5, the driving closing MICBIAS waits.

Optionally, agreement MIC line transmitted with timesharing and/or frequency dividing mode is the single wire transmission agreement transmitted with frame, often Frame data comprise clock data, information data and power data.Described clock data is fixed interval, defines a frame data side Boundary, information data and power data can be mutually mixed and with fixing or dynamical fashion arrangement.

Described clock data, the high level of downlink information data and power data is all for providing electric energy.Power data area Between can be configured to downlink transmission data or be configured to high level and only transmit electric energy.Main frame passes through downlink data " 1 " or power supply number It is powered according to headset, and frequently one-tenth degree main frame of powering can carry out open loop dynamic regulation or by the electrical energy demands of headset to simulate Or digital signal form uploads main frame and realizes closed loop regulation.Described headset insertion main process equipment or described main frame are inserted into headset When, after described headset identification insertion main frame or described main frame identification insertion headset, configure described headset or institute according to default setting State main frame.

To sum up, in numeral headset provided by the utility model and headset system, by the L channel earplug in headset And in R channel earplug, it is respectively provided with the first digital microphone and the second digital microphone, panel arranges main microphon mould Block, thus the single analog mike that headset of the prior art is adopted replaces with multiple digital mike, is greatly improved The anti-interference of headset, thus improve the tonequality of headset；On the other hand, due to being provided with slave modular converter in panel, It is provided with main frame modular converter, it is possible to achieve the data exchange between headset and main frame, the data message in headset can in main frame Processed with being transferred to main frame, reduced the space required for headset and power consumption；On the other hand, due in the panel of headset It is provided with clock and power supply extraction module, clock information and energy needed for headset can be extracted in microphone lines by it, Without additional power source so that headset works, greatly reduce the design volume of headset.

Foregoing description is only the description to this utility model preferred embodiment, not any limit to this utility model scope Fixed, any change that the those of ordinary skill in this utility model field does according to the disclosure above content, modification, belonging to right will Seek the protection domain of book.
