For earphone, some important parameters are arranged, as follows:
1) impedance of earphone, i.e. resistance and reactance on vector and.Have at desktop computer or power amplifier, VCD, DVD TV etc. on the machine of earphone jack output, the earphone of high impedance is more suitable in general the use.If use the low-resistance earphone, necessarily to turn down volume more earlier and plug in the earphone, little by little volume is transferred up again, prevention earphone overload burns out earphone or voice coil loudspeaker voice coil distortion dislocation causes distorsion, the earphone of impedance generally promotes than being easier to, therefore machine portable, power saving such as walkman should be selected the Low ESR earphone, is also noted that simultaneously sensitivity wants high, and sensitivity index is more important concerning walkman.
2) sensitivity of earphone, the sound pressure level (unit of acoustic pressure is a decibel, and the big more volume of acoustic pressure is big more) that earphone can send when pointing to earphone and importing the power of 1 milliwatt, so generally sensitivity is high more, impedance is more little, earphone is easy more speaks, easy more driving.Popular says, the sensitivity of earphone just is meant under the same situation here, needs the size of the power of input, and the high more needed input power of sensitivity is more little.For portable equipments such as walkmans, sensitivity is a very index of significant.
3) the transducing mode of earphone: according to its transducing mode, mainly be divided into the moving-coil mode, electrostatic and etc. magnetic-type.
4) form of wearing of earphone: according to its wearing mode, mainly be divided into ear type, ear suspension type and head-type.
5) earphone is simulation or numeral: traditional earphone is for simulating, as shown in Figure 1.Audio signal enters with simulated mode, directly outputs to earphone and drives the coil of earphone.Digital earphone receives digital audio and video signals, carries out the coil of digital-to-analogue conversion rear drive earphone in earphone.More senior digital earphone also comprises audio decoding unit, is used for input signal is decoded, and audio treatment unit, be used for that digital audio is carried out audio and handle.
6) if whether digital earphone has audio decoding unit.Audio decoding unit can be decoded to the audio digital signals stream of the different-format that transmits, as PCM(Pulse Code Modulation, pulse code modulation) form, MP3 format, WMA (Windows Media Audio) form, RA(RealAudio) form, or the like.
7) if having audio decoding unit, support which form, as PCM(Pulse Code Modulation, pulse code modulation) form, MP3 format, WMA (Windows Media Audio) form, RA(RealAudio) form, or the like.
8) whether have the audio processing unit.
9) earphone communication modes: wired earphone, wireless headset, still wire/wireless earphone, wherein, the wire/wireless earphone is meant that earphone both can be used as wired earphone, also can be used as wireless headset, depended on user's selection.
10) earphone sound channel: monophony, dual track, multitrack surround sound, or the like.
11) frequency response curve of earphone.Fig. 3 is the frequency response curve of earphone, be that the pairing sensitivity number of frequency is exactly frequency response, it is exactly frequency response curve that drafting pattern looks like, and the scope that the human auditory can reach is greatly about 20Hz-20000Hz, and ripe at present earphone technology has all reached this requirement.Outstanding earphone frequency response width can reach 5Hz-40000Hz.As we can see from the figure, the frequency response width of this earphone is 20Hz-20000Hz, at 200Hz to having Frequency Response preferably between the 15000Hz.Fig. 4 has provided the pairing amplitude of each Frequency point of earphone response curve shown in Figure 3 with the form of tabulation.
Fig. 5 is one of typical architecture figure of earphone of the present invention.Audio signal is exported from audiogenic device, enter earphone by audio signal interface, audio decoding unit is decoded to the audio signal data stream of input, audio treatment unit carries out audio to decoded audio signal to be handled, as bass strengthen, voice is clear, or the like, the mode that has a lot of audios to handle in the prior art.The signal of handling through audio just can output to the earphone driver element through after the digital-to-analogue conversion, as coil.Control signal is used for earphone and audiogenic device is mutual, exports to the main control unit of earphone, and main control unit not only can be controlled inner each unit, but also can communicate by letter transfer control signal with audiogenic device.The earphone parameter of being mentioned above the storage of ear-phone function properties store is typically E2PROM memory or FLASH memory.In addition, memory can be independent, also can with control program together, as the data of program, audiogenic device obtains this data by communicating by letter with earphone.In addition, data also can be independent E2PROM, when audiogenic device with after earphone is connected, this memory is as the part of audiogenic device, but it is physically located in the earphone, audiogenic device is as long as adopt the mode of operation of common E2PROM just can read these data, the DDC(DISPLAY DATA CHNNEL in this mode principle and the display, DDC) basic identical in the agreement.After the earphone audiogenic device reads these parameters, just can change the configuration of self according to these parameters, optimize internal control and adjust the mode that audio frequency is exported.Liquid crystal display is used for the demonstration of the important information of earphone.Push-button unit promptly is used for the control of earphone self, also as line traffic control Equipment Control audiogenic device.After power supply was input to earphone, power distribution unit was each unit electrical power distribution just, to support the running of each several part normal function.
For better explanation the present invention, the data of ear-phone function properties store storage are as follows:
1) impedance of earphone: 200 ohm;
2) sensitivity of earphone: 65db;
3) the transducing mode of earphone: moving-coil mode;
4) form of wearing of earphone: ear type;
5) earphone is simulation or numeral: numeral;
6) have audio decoding unit;
7) support form: PCM, MP3, WMA;
8) have the audio processing unit;
9) earphone communication modes: wired earphone;
10) sound channel of earphone: dual track;
11) frequency response curve of earphone: data as shown in Figure 4.
By the data of storing above, audiogenic device is just known the functional characteristic of earphone, thereby changes the control of himself and the output of audio signal and control signal, explanation respectively below according to the functional characteristic of earphone.
1) impedance of earphone: obtain the impedance of earphone when audiogenic device after,, regulate the output volume of earphone automatically according to the size of impedance.The impedance of earphone is divided according to high, normal, basic, if the impedance of earphone is lower than 16 ohm, then belongs to Low ESR; If be higher than 16 ohm and, then belong to middle impedance less than 100 ohm; If be higher than 100 ohm, then belong to high impedance.After if audiogenic device reads the impedance of earphone, judge that it is a Low ESR, then audiogenic device should not exported excessive volume, in order to avoid burn out earphone, perhaps damages user's ear, especially inserts the moment of earphone the user.For instance, for the Low ESR earphone, if audiogenic device output volume value is bigger when connecting earphone, then audiogenic device can be adjusted to a suitable lower value with volume output automatically, after this allow user oneself go to regulate again, avoid inserting earphone moment damage earphone according to own needs; Equally, for the bigger melody of dynamic range, in the high pitch zone, if this moment, the output volume value was bigger, also might damage earphone, when the situation that runs into high pitch, if output volume is than higher at this moment, then system reduces volume to a suitable value automatically, avoids burning out earphone.For impedance is middle and high rank earphone, when running into above-mentioned situation, then the volume threshold value that needs can be regulated be provided with higher, perhaps more simply, audiogenic device is to any processing of volume output not carrying out.
2) sensitivity of earphone: sensitivity is related with the impedance phase of earphone usually, and general impedance is low, sensitivity meeting height; The impedance height, sensitivity is low.Audiogenic device obtains this parameter and is used for the parameter demonstration, is about to parameter and shows on the display unit of audiogenic device, perhaps is used to adapt to certain needs of audiogenic device in the future.
3) the transducing mode of earphone: be used to adapt to certain needs of audiogenic device in the future here.
4) form of wearing of earphone: audiogenic device is according to the form of wearing of earphone, shows that with different figures different earphones wears form, and as shown in Figure 6, wherein A is an ear type, and B is an ear suspension type, and C is a head-type.
5) earphone is simulation or numeral: if earphone is simulated, then system directly exports the audio signal of simulation, if earphone is digital, then exports digital signal, but concrete form will be decided according to the parameter of back.
6) have audio decoding unit: if having audio decoding unit, then can export through coded digital audio signals, coded format is with reference to the support format parameter of back.If there is not audio decoding unit, then must export through decoded audio digital signals, output to earphone through decoded digital audio and video signals with the PCM form, export through after the digital-to-analogue conversion then.
7) support form: support that form shows the form that the earphone decoding unit can be decoded.When audiogenic device and earphone decoding unit are all supported certain audio format, the audiogenic device back output output of also can not decoding of can decoding.When audiogenic device is supported certain audio format and earphone decoding unit when not supporting, audiogenic device is decoded and is outputed to earphone with the PCM form behind this audio format; When audiogenic device is not supported certain audio format, and the earphone decoding unit is supported this audio format, then audiogenic device output not the voice data of decoding give earphone, for earphone decoding output.When audiogenic device and earphone decoding unit were not supported certain audio format, audiogenic device just shows did not support this audio format.Like this, when earphone was not connected with audiogenic device, audiogenic device externally showed the decoding capability that himself had, i.e. its form that can decode; When earphone was connected with audiogenic device, audiogenic device externally showed the decoding capability that decoding capability and earphone possessed that himself had.
8) if earphone has the audio processing unit, then the audio disposal ability of audiogenic device is exactly the audio disposal ability of audiogenic device and the summation of earphone audio disposal ability, it is to carry out audio by earphone or audiogenic device separately to handle that system can select, still come together to carry out audio and handle, perhaps do not carry out audio and handle and directly output.
9) earphone communication modes: audiogenic device shows different earphone communication modes according to the communication modes of earphone with different figures, just the communication modes supported of earphone.Audiogenic device promptly shows the communication modes that earphone is supported, also show the working method that earphone is current, especially for the wire/wireless earphone, system can show that its working method is wired or wireless, shows the communication modes that earphone is supported simultaneously according to current communication modes.Fig. 7 is the demonstration schematic diagram of several communication modes of earphone, and wherein A is a wired earphone, and B is a wireless headset, and C is the wire/wireless earphone, and the work at present mode is wired mode, and D is the wire/wireless earphone, and the work at present mode is a wireless mode.
10) sound channel of earphone: according to the channel information of earphone, and the sound channel of current broadcast program provides different output.If program is a monophony, then, all only export monophony no matter what type earphone is.If program is a dual track,, three kinds of selections are just arranged: L channel, R channel and left and right acoustic channels synthetic for mono headset; For dual-channel headphone, then directly output; For multi-sound-channel earphone, also only export left and right acoustic channels.If program is a multichannel, for mono headset, and dual-channel headphone, multiple combining form output can be arranged; For multi-sound-channel earphone, then directly export multi-channel audio signal.
11) frequency response curve of earphone: after each Frequency point of audiogenic device reading frequency response curve and the corresponding amplitude, then output audio signal is handled according to this curve.It below is several frequently seen processing mode.
The A mode: audiogenic device is according to the frequency response curve of earphone, obtain the frequency range of putting up the best performance, for Fig. 4, the optimum frequency scope is 200Hz to 15000Hz, then audiogenic device is only handled the audio signal of this scope, do not handle exceeding then can ignoring of this scope, thereby improve the processing speed of system.
The B mode: for the frequency response curve of desirable earphone, its curve should be a horizontal line, and promptly the response to each frequency all is the same, but reality is difficult to accomplish.For this reason, audiogenic device can be handled audio signal according to certain algorithm, thereby obtains the effect of approximate ideal.Simple processing mode is: the average response amplitude of obtaining earphone optimum frequency scope, then according to this average response amplitude, audio signal to each frequency, difference according to its actual response amplitude and average response amplitude, exceed the average response amplitude, reduce the output intensity of this frequency when then audio is handled, be lower than the average response amplitude, increase the output intensity of this frequency when then audio is handled, the output of synthetic at last back.With Fig. 4 is example, and 200Hz to 15000Hz is the optimum frequency scope, and its average response amplitude is:
（（-5）+（-3）+（-0.5）+0+3+（-3）+2+（-5））/8?=?-1.43（dBr）
From top calculating as can be seen, it gets the mean value of the response amplitude of characteristic frequency.For 200Hz, its actual response amplitude is-5, does not reach-1.43, and then the audio processing unit is exported after can improving this frequency component 3.57dBr again.For 10000Hz, its actual response amplitude is 2, surpasses-1.43, and then the audio processing unit is exported after can reducing this frequency component 3.43dBr again.Each is variant for actual processing possibility, but basic principle is all basic identical or approximate.
Described functional characteristic data how to pass through the earphone of storage above, audiogenic device changes the control of himself and the output of audio signal and control signal according to the functional characteristic of earphone.From integral body the how collaborative work of audiogenic device and earphone is described below.
Fig. 8 is the switching sequence of individual channel between audiogenic device and the earphone.When audiogenic device is started shooting, at first connect the earphone power supply, open the control signal path between audiogenic device and the earphone then, next, open audio signal path.At this moment, system begins operate as normal.When shutdown system, at first, close audio signal path, the closing control signal path is closed the power path between connection audiogenic device and the earphone at last or is closed earphone power supply (when earphone is independently-powered) then.
Fig. 9 is individual channel switching sequence figure between audiogenic device and the earphone.Behind the earphone electric power starting, open control signal in the T1 time, the T2 time is opened audio signal, and the T3 time is closed audio signal, T4 time closing control signal, and the T5 time is closed the earphone power supply.In general, T1＜T2＜T3＜T4＜T5, but T3, T4 and T5 can equate.
Figure 10 adopts the present invention program's audiogenic device to be connected control method afterwards with earphone.At first, audiogenic device reads the functional characteristic data of storing on the ear-phone function properties store, and then, the audio frequency that audiogenic device is adjusted audiogenic device according to the functional characteristic data is exported Control Parameter, last output audio signal.For different functional characteristic data tones source devices different ways is arranged, also there is description the front, repeats no more here.
