Detailed description of the invention
The cardinal principle of the present invention is addition ear-phone function properties store in earphone, has power interface, control signal interface and audio signal interface between audiogenic device and earphone.
Fig. 2 is embodiments of the invention schematic diagrams.There is between audiogenic device and earphone power interface, control signal interface and audio signal interface, wherein, power interface is for powering to earphone, and audio signal interface is for providing audio signal to earphone, and control signal interface is mutual for communicating between audiogenic device and earphone.By controlling interface, mutual operation functionally can not only be carried out between audiogenic device and earphone, as controlled audiogenic device by the button on earphone, such as volume adjusting, song selection etc., and audiogenic device can pass through control interface and read the ear-phone function performance data stored in earphone functional characteristic memorizer in earphone, audiogenic device exports after changing the audio signal format exported according to the functional characteristic data obtained or according to the functional characteristic data obtained, audio signal is carried out audio effect processing.It is pointed out that the interface described in the present invention, it is possible to be wireline interface, it is also possible to be wave point.These interfaces can be separate, it is also possible to is merge.Typically, USB(UniversalSerialBus, USB (universal serial bus)) needs of the present invention can well be adapted to, it both can as charging inlet, it is also possible to as controlling interface, it is also possible to as audio interface.
For earphone, there is the parameter that some are important, as follows.
1) impedance of earphone, namely resistance and reactance on vector and.Have on the machine that earphone jack exports at desktop computer or power amplifier, VCD, DVD TV etc., generally use the earphone ratio of middle high impedance conveniently.If using low-resistance earphone, necessarily first turning down sound volume is plugged in the earphone again, little by little volume is adjusted up again, stop earphone overload to be burnt out by earphone or voice coil loudspeaker voice coil deformation dislocation causes distorsion, low-impedance earphone is generally easier to promote, therefore the machine portable, power saving such as walkman should select Low ESR earphone, is also noted that height is wanted in sensitivity simultaneously, and walkman sensitivity index is more important.
2) sensitivity of earphone, the sound pressure level (unit of acoustic pressure is decibel, and the more big volume of acoustic pressure is more big) that when sensing earphone inputs the power of 1 milliwatt, earphone can send, so general, sensitivity is more high, impedance is more little, and earphone is more easily spoken, more easily driven.Popular says, the sensitivity of earphone refer to when same here, it is necessary to the size of the power of input, the more high required input power of sensitivity is more little.For portable equipments such as walkmans, sensitivity is the index of a very significant.
3) the transducing mode of earphone: according to its transducing mode, be broadly divided into moving-coil mode, electrostatic and etc. magnetic-type.
4) the wearing form of earphone: according to its wearing mode, be broadly divided into ear type, ear suspension type and head-type.
5) earphone is simulation or numeral: traditional earphone is simulation, as shown in Figure 1.Audio signal enters in an analog manner, is directly output 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.The digital earphone of higher level also includes audio decoding unit, for input signal is decoded, and audio treatment unit, for DAB is carried out audio effect processing.
6) if digital earphone, if with audio decoding unit.The audio digital signals stream of the different-format transmitted can be decoded by audio decoding unit, such as PCM(PulseCodeModulation, pulse code modulation) form, MP3 format, WMA(WindowsMediaAudio) form, RA(RealAudio) form, etc..
7) if with audio decoding unit, support which form, such as PCM(PulseCodeModulation, pulse code modulation) form, MP3 format, WMA(WindowsMediaAudio) form, RA(RealAudio) form, etc..
8) whether with audio effect processing unit.
9) earphone communication modes: wired earphone, wireless headset or wire/wireless earphone, wherein, wire/wireless earphone refers to that earphone both can as wired earphone, the selection that as wireless headset, can also depend on user.
10) earphone sound channel: monophonic, double track, multitrack surround sound, etc..
11) frequency response curve of earphone.Fig. 3 is the frequency response curve of earphone, namely the sensitivity number corresponding to frequency is exactly frequency response, drafting pattern picture is exactly frequency response curve, and the scope that human auditory can reach is approximately in 20Hz-20000Hz, and earphone technique ripe at present has been reached this requirement.Outstanding earphone frequency response width is up to 5Hz-40000Hz.From the figure, it can be seen that the frequency response width of this earphone is 20Hz-20000Hz, there is between 200Hz to 15000Hz good Frequency Response.Fig. 4 gives the amplitude corresponding to each Frequency point of earphone response curve shown in Fig. 3 in the form of a list.
Fig. 5 is one of typical architecture figure of earphone of the present invention.Audio signal exports from audiogenic device, earphone is entered by audio signal interface, the audio signal data stream of input is decoded by audio decoding unit, decoded audio signal is carried out audio effect processing by audio treatment unit, as clear in bass boost, voice, etc., there is the mode of a lot of audio effect processing in the prior art.Signal through audio effect processing just can export earphone driver element after digital-to-analogue conversion, such as coil.Control signal is mutual with audiogenic device for earphone, exports to the main control unit of earphone, and main control unit is possible not only to internal unit is controlled, but also with audiogenic device communication, can transmit control signal.The earphone parameter that the storage of ear-phone function properties store is mentioned above, it is typical that E2PROM memorizer or FLASH memory.It addition, memorizer can be independent, it is also possible to together with controlling program, as the data of program, audiogenic device is by obtaining this data with earphone communication.Additionally, data can also be independent E2PROM, after audiogenic device is connected with earphone, this memorizer is as a part for audiogenic device, but it is physically located in earphone, as long as audiogenic device adopts the mode of operation of common E2PROM just can read these data, this mode principle and the DDC(DISPLAYDATACHNNEL in display, DDC) essentially identical in agreement.After earphone audiogenic device reads these parameters, it is possible to change the configuration of self according to these parameters, optimize internal control and adjust the mode of audio frequency output.Liquid crystal display is for the display of the important information of earphone.Push-button unit, namely for the control of earphone self, also serves as line traffic control equipment and controls audiogenic device.After power supply is input to earphone, power distribution unit just distributes electric power for unit, to support the running of each several part normal function.
In order to better illustrate 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) 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 functional characteristic according to earphone changes the control of himself and the output of audio signal and control signal, illustrates separately below.
1) impedance of earphone: after audiogenic device obtains the impedance of earphone, the size according to impedance, it is automatically adjusted the output volume of earphone.The impedance of earphone divides according to high, normal, basic, if the impedance of earphone is lower 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 after audiogenic 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, the moment of earphone is inserted particularly in user.For example, for Low ESR earphone, during if switch on earphone, audiogenic device output volume value is relatively big, then volume output can be adjusted a suitable relatively low value by audiogenic device automatically, hereafter allow user oneself according to oneself needing to go to regulate again, it is to avoid inserting earphone transient breakdown earphone；Similarly, for the melody that dynamic range is bigger, in treble region, if now output volume value is relatively larger, it is also possible to damage earphone, when the situation running into 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.Being middle and high rank earphone for impedance, when running into above-mentioned situation, then what can the volume threshold value that need to regulate be arranged is higher, or simply a bit, volume output is not carried out any process by audiogenic device.
2) sensitivity of earphone: sensitivity is generally associated with the impedance of earphone, and general impedance is low, sensitivity can height；Impedance is high, and sensitivity is low.Audiogenic device obtains this parameter and shows for parameter, shows on the display unit of audiogenic device by parameter, 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 that form worn by different earphones with different figures, 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, if earphone is digital, then and 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 digital audio and video signals, coded format is with reference to support format parameter below.Without audio decoding unit, then must export through decoded audio digital signals, export earphone through decoded digital audio and video signals with PCM format, export after being then passed through digital-to-analogue conversion.
7) form is supported: support that form shows the form that earphone decoding unit can decode that.When audiogenic device and earphone decoding unit all support certain audio format time, audiogenic device can export after decoding can not also decode output.When audiogenic device supports certain audio format time, earphone decoding unit is not supported, audiogenic device exports earphone with PCM format after decoding this audio format；When audiogenic device does not support certain audio format, and earphone decoding unit supports this audio format, then the voice data that audiogenic device output does not decode is to earphone, for earphone decoding output.When audiogenic device and earphone decoding unit do not support certain audio format time, this audio format is not supported in audiogenic device just display.So, when earphone is not connected with audiogenic device time, audiogenic device externally shows the decoding capability himself having, i.e. its form that can decode；When earphone is connected with audiogenic device time, audiogenic device externally shows the decoding capability that the decoding capability himself having and earphone possess.
8) if earphone is with audio effect processing unit, then the audio effect processing ability of audiogenic device is exactly the summation of the audio effect processing ability of audiogenic device and earphone audio effect processing ability, system can select to be individually carried out audio effect processing by earphone or audiogenic device, still come together to carry out audio effect processing, or do not carry out audio effect processing and directly export.
9) earphone communication modes: the audiogenic device communication modes according to earphone, shows different earphone communication modes, the communication modes that namely earphone is supported with different figures.Namely audiogenic device shows the communication modes that earphone is supported, display that the working method that earphone is current, particularly with wire/wireless earphone, according to Current communications mode, system can show that its working method is wired or wireless, show the communication modes that earphone is supported simultaneously.Fig. 7 is the display schematic diagram of several communication modes of earphone, and wherein A is wired earphone, and B is wireless headset, and C is wire/wireless earphone, and work at present mode is wired mode, and D is wire/wireless earphone, and work at present mode is wireless mode.
10) sound channel of earphone: the channel information according to earphone, and the sound channel of currently played program provides different output.If program is monophonic, then no matter what type earphone is, all 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, then directly export；For multi-sound-channel earphone, also only export left and right acoustic channels.If program is multichannel, for mono headset, and dual-channel headphone, multiple combination form can be had to export；For multi-sound-channel earphone, then direct output multi-channel audio signal.
11) frequency response curve of earphone: after audiogenic device each Frequency point of reading frequency response curve and accordingly amplitude, then process output audio signal according to this curve.The following is several frequently seen processing mode:
A mode: the audiogenic device frequency response curve according to earphone, obtain the frequency range put up the best performance, for Fig. 4, Best Frequency Range is 200Hz to 15000Hz, then the audio signal of this scope is only processed by audiogenic device, do not process beyond then can ignoring of this scope, thus improving the processing speed of system.
B mode: for the frequency response curve of desirable earphone, its curve should be a horizontal line, namely the response of each frequency is just as, but reality is difficult to accomplish.For this, audio signal can be processed by audiogenic device according to certain algorithm, thus obtaining the effect of approximate ideal.Simple processing mode is: obtain the average response amplitude of earphone Best Frequency Range, then according to this average response amplitude, audio signal to each frequency, difference according to its actual response amplitude Yu average response amplitude, exceed average response amplitude, then reduce the output intensity of this frequency during audio effect processing, lower than average response amplitude, then increase the output intensity of this frequency during audio effect processing, export after being finally synthesizing.For Fig. 4,200Hz to 15000Hz for 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 actual response amplitude is-5, and not up to-1.43, then 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 audio effect processing unit exports after can reducing this frequency component 3.43dBr again.Actual process is likely to each variant, but ultimate principle is substantially the same or is similar to.
It is described above how the functional characteristic data of the earphone by storing, audiogenic device changes the control of himself and the output of audio signal and control signal according to the functional characteristic of earphone.From entirety, 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 earphone.When audiogenic device is started shooting, first connect earphone power supply, then open the control signal path between audiogenic device and earphone, it follows that open audio signal path.At this moment, system starts normal operation.When the system is shut down, first, close audio signal path, be then shut off control signal path, finally close the power path connected between audiogenic device and earphone or close earphone power supply (when earphone is independently-powered).
Fig. 9 is individual channel switching sequence figure between audiogenic device and earphone.After earphone electric power starting, opening control signal in the T1 time, the T2 time opens audio signal, and the T3 time closes audio signal, and T4 time closing control signal, the T5 time closes earphone power supply.In general, T1 < T2 < T3 < T4 < T5, but T3, T4 and T5 can be equal.
Figure 10 is the control method after adopting the audiogenic device of the present invention program and earphone to connect.First, audiogenic device reads the functional characteristic data of storage in ear-phone function properties store, and then, audiogenic device exports according to the audio frequency of functional characteristic data point reuse audiogenic device and controls parameter, finally exports audio signal.Have different ways for different functional characteristic data tones source devices, before also have description, repeat no more here.
The one that Figure 11 is the earphone of the present invention simplifies plate rack composition.Audio signal exports from audiogenic device, enters earphone by audio signal interface and exports loudspeaker.Control signal is mutual with audiogenic device for earphone, exports to the main control unit of earphone, and main control unit is possible not only to internal unit is controlled, but also with audiogenic device communication, can transmit control signal.The earphone parameter that the storage of ear-phone function properties store is mentioned above, it is typical that E2PROM memorizer.After audiogenic device reads these parameters, it is possible to change the configuration of self according to these parameters, optimize internal control and adjust the mode of audio frequency output.After power supply is input to earphone, power distribution unit just distributes electric power for unit, to support the running of each several part normal function.
Figure 12 is the Organization Chart of the wire/wireless earphone of the present invention.This earphone had both included wireline interface, also included wave point.Can transmission of control signals and audio signal from wireline interface and wave point.Isolated audio signal flows to loudspeaker, and isolated control signal exports to the main control unit of earphone, and main control unit is possible not only to internal unit is controlled, but also with audiogenic device communication, can transmit control signal.The earphone parameter that the storage of ear-phone function properties store is mentioned above, it is typical that E2PROM memorizer.After audiogenic device reads these parameters, it is possible to change the configuration of self according to these parameters, optimize internal control and adjust the mode of audio frequency output.After power supply is input to earphone, power distribution unit just distributes electric power for unit, to support the running of each several part normal function.It is pointed out that first this embodiment there is provided the Novel earphone of a kind of compatible for wired/wireless, followed by providing ear-phone function properties store.Audio signal, control signal fusion separation method there is multifarious selection, however it is not limited to the present embodiment, the separation such as audio signal and control signal can be completed by main control unit.For wire/wireless earphone, maximum benefit is that user can select, although wireline interface is less user friendly, but not radiation, and wave point is to have bigger radiation.If audiogenic device and headset detection are to wired connection, the transmission of wave point can be terminated, in turn, if be detected that during wired disconnection, both sides will start wave point.And, when wire transmission, power supply is also a part for wireline interface, it is possible to power pack is charged, and provides electric power for various piece；When being wirelessly transferred, earphone internal electric source is started working, and provides electric power for various piece.
It is last it is noted that above example is only in order to illustrative not limiting technical scheme; the present invention can be modified or equivalent replacement by those of ordinary skill in the art; without deviating from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the claims of the present invention.
