2) sensitivity of earphone: 65db；
3) the transducing mode of earphone: moving-coil mode；
4) the wearing form of earphone: ear type；
5) earphone is simulation or numeral: numeral；
6) with audio decoding unit；
7) form is supported: PCM, MP3, WMA；
8) with audio effect processing unit；
9) earphone communication modes: wired earphone；
10) sound channel of earphone: double track；
11) frequency response curve of earphone: data are as shown in Figure 4.
By the data stored above, audiogenic device is known that the functional characteristic of earphone, thus the function according to earphone is special
Property changes himself control and audio signal and the output of control signal, illustrates separately below.
1) impedance of earphone: after audiogenic device obtains the impedance of earphone, according to the size of impedance, be automatically adjusted earphone
Output volume.The impedance of earphone divides according to high, normal, basic, if the impedance of earphone is less than 16 ohm, then belongs to Low ESR；
If above 16 ohm and less than 100 ohm, then belong to middle impedance；If above 100 ohm, then belong to high impedance.If sound
After source device reads the impedance of earphone, it is judged that it is Low ESR, then audiogenic device should not export excessive volume, in order to avoid burning out
Earphone, or the ear of impaired user, especially insert the moment of earphone user.For example, for Low ESR earphone, as
When fruit connects earphone, audiogenic device output volume value is relatively big, then volume output can be adjusted to one suitably by audiogenic device automatically
Relatively low value, allows user oneself need to go regulation according to oneself, it is to avoid inserting earphone transient breakdown earphone the most again；Equally,
For the melody that dynamic range is bigger, in treble region, if now output volume value is bigger, it is also possible to damage earphone,
When running into the situation of high pitch, if now output volume is higher, then system reduces the suitable value of volume to automatically, it is to avoid
Burn out earphone.It is middle and high rank earphone for impedance, when running into above-mentioned situation, then can will need the volume threshold value of regulation
Arrange is higher, or the most a bit, audiogenic device does not carry out any process to volume output.
2) sensitivity of earphone: sensitivity is generally associated with the impedance of earphone, and general impedance is low, sensitivity can height；Resistance
Anti-height, sensitivity is low.Audiogenic device obtains this parameter and shows for parameter, will parameter show on the display unit of audiogenic device
Illustrate, or for adapting to certain needs of audiogenic device in the future.
3) the transducing mode of earphone: here for adapting to certain needs of audiogenic device in the future.
4) the wearing form of earphone: audiogenic device wears form according to earphone, shows different with different figures
Form worn by earphone, and as shown in Figure 6, wherein A is ear type, and B is ear suspension type, and C is head-type.
5) earphone is simulation or numeral: if earphone is simulation, then system directly exports the audio signal of simulation, as
Really earphone is digital, then output digit signals, but concrete form to be determined according to parameter below.
6) with audio decoding unit: if with audio decoding unit, then can export encoded DAB
Signal, coded format is with reference to support format parameter below.Without audio decoding unit, then must export after decoding
Audio digital signals, export earphone through decoded digital audio and video signals with PCM format, after being then passed through digital-to-analogue conversion
Output.
7) form is supported: support that form shows the form that earphone decoding unit can decode that.When audiogenic device and earphone solution
The when that code unit all supporting certain audio format, audiogenic device can export after decoding can not also decode output.Work as source of sound
The when that equipment supporting certain audio format and time earphone decoding unit is not supported, audiogenic device decode after this audio format with
PCM format exports earphone；When audiogenic device does not support certain audio format, and earphone decoding unit supports this audio format,
The voice data that then audiogenic device output does not decodes is to earphone, for earphone decoding output.When audiogenic device and earphone decoding unit
The when of the most not supporting certain audio format, this audio format is not supported in audiogenic device just display.So, when earphone not with source of sound
The when that equipment connecting, audiogenic device externally shows the decoding capability himself being had, i.e. its form that can decode；Work as earphone
The when of connection with audiogenic device, audiogenic device externally shows the solution that the decoding capability himself being had and earphone are possessed
Code ability.
8) if earphone is with audio effect processing unit, then the audio effect processing ability of audiogenic device is exactly the audio of audiogenic device
Disposal ability and the summation of earphone audio effect processing ability, system can select to be individually to be carried out sound by earphone or audiogenic device
Effect processes, and still comes together to carry out audio effect processing, or does not carries out audio effect processing and directly export.
9) earphone communication modes: audiogenic device, according to the communication modes of earphone, shows different ears with different figures
Machine communication modes, the communication modes that namely earphone is supported.Audiogenic device i.e. shows the communication modes that earphone is supported, also shows
Showing the working method that earphone is current, particularly with wire/wireless earphone, system can show its work according to Current communications mode
Mode is wired or wireless, shows the communication modes that earphone is supported simultaneously.Fig. 7 is that the display of several communication modes of earphone is shown
Being intended to, wherein A is wired earphone, and B is wireless headset, and C is wire/wireless earphone, and work at present mode is wired mode, D
For wire/wireless earphone, and work at present mode is wireless mode.
10) sound channel of earphone: according to the channel information of earphone, and the sound channel of currently played program provides not
Same output.If program is monophonic, then no matter what type earphone is, the most only exports monophonic.If program is double track,
For mono headset, just there are three kinds of selections: the synthesis of L channel, R channel and left and right acoustic channels；For dual-channel headphone,
The most directly export；For multi-sound-channel earphone, the most only export left and right acoustic channels.If program is multichannel, for mono headset, and
Dual-channel headphone, can have multiple combination form to export；For multi-sound-channel earphone, then direct output multi-channel audio signal.
11) frequency response curve of earphone: audiogenic device each Frequency point of reading frequency response curve and corresponding width
After degree, then according to this curve, output audio signal is processed.The following is several frequently seen processing mode:
A mode: audiogenic device, according to the frequency response curve of earphone, obtains the frequency range put up the best performance, for Fig. 4, most preferably
Frequency range is 200Hz to 15000Hz, then the audio signal of this scope is only processed, to beyond this scope by audiogenic device
Then can ignore and not process, thus improve the processing speed of system.
B mode: for the frequency response curve of preferable earphone, its curve should be a horizontal line, i.e. to each frequency
Response be just as, but reality is difficult to accomplish.To this end, audio signal can be carried out by audiogenic device according to certain algorithm
Process, thus obtain the effect of approximate ideal.Simple processing mode is: obtain the average response width of earphone Best Frequency Range
Degree, then according to this average response amplitude, the audio signal to each frequency, according to its actual response amplitude and average response width
The difference of degree, exceeds average response amplitude, then reduces the output intensity of this frequency during audio effect processing, less than average response amplitude
, then increase the output intensity of this frequency during audio effect processing, export after being finally synthesizing.As a example by Fig. 4,200Hz to 15000Hz is
Best Frequency Range, its average response amplitude is:
((-5)+(-3)+(-0.5)+0+3+(-3)+2+(-5))/8=-1.43(dBr)
From calculating it can be seen that it takes the meansigma methods of response amplitude of characteristic frequency above.For 200Hz, its real response
Amplitude is-5, not up to-1.43, then and audio effect processing unit exports after can improving this frequency component 3.57dBr again.For
10000Hz, its actual response amplitude is 2, exceedes-1.43, then after audio effect processing unit can reduce this frequency component 3.43dBr
Export again.Actual process may be each variant, but ultimate principle is substantially the same or approximates.
It is described above how the functional characteristic data of the earphone by storage, audiogenic device is according to the functional characteristic of earphone
Change himself control and audio signal and the output of control signal.From entirety, audiogenic device and earphone are described below
How collaborative work.
