Detailed description of the invention

Below with reference to accompanying drawing, each embodiment of the present utility model is given elaboration further.

First, the most basic structure of this utility model is described:

First embodiment

Referring to Fig. 1, a kind of headset, have headset main body and audio interface, wherein audio interface includes at least one Lightning interface, Lightning interface is for being connected with outside Fructus Mali pumilae equipment；Headset main body includes earphone and mike, two Person respectively with the signal communication in Lightning interface, formed for the audio signal of described outside Fructus Mali pumilae equipment is inputted extremely The audio signal input channel of described headset and for the audio signal of mike being exported the sound to the most described outside Fructus Mali pumilae equipment Frequently signal output channels.Headset main body also includes audio effect processing unit, electrically connects with described AD conversion unit outfan, is used for The dry acoustical signal gathering described mike carries out output extremely described MFI authentication ' unit or described digital-to-analogue conversion after audio effect processing Unit.

So the various acoustical signals of mike collection can be exported to outside Fructus Mali pumilae equipment by Lightning interface, Can also be by the dry sound of audio effect processing unit sweetly disposition mike input, outside Fructus Mali pumilae equipment or earphone are given in output.

Second, the several key concept of following description and optimized integration:

1, audio effect processing unit.Audio effect processing unit specifically can be by the various digital processing cores loading corresponding audio algorithm Sheet realizes, a kind of specific works pattern of every kind of algorithm correspondence digital processing chip.

2, dry sound and wet sound.Dry acoustical signal refers to the primitive man's acoustical signal without audio frequency special effect processing such as filtered voices, line Property signal amplify with decay be also dry sound；Wet acoustical signal refers to the human voice signal after the audio frequency special effect processing such as filtered voice.

3, primary sound and accompaniment.Primary sound refers to be mixed in the voice of singer in song and music；After accompaniment is removal voice Music.

3rd, on the basis of first embodiment, this utility model can also optimize further:

Second embodiment

This embodiment adds downmixing unit on the basis of first embodiment, and the connection of audio effect processing Unit selection is defeated at audio frequency Go out on the main road of passage, load voice Processing Algorithm.Referring to Fig. 2, the operation principle of this embodiment is: the input of mike Dry acoustical signal is formed wet sound after audio effect processing and is recorded to outside Fructus Mali pumilae equipment by the output of Lightning interface；Outward The accompaniment signal of portion Fructus Mali pumilae equipment input and the dry acoustical signal of mike input by deliver to after the audio mixing of downmixing unit earphone by User monitors.

So earphone exports dry sound, and outside Fructus Mali pumilae equipment is exported wet sound, it is achieved listen dry record wet.

3rd embodiment

This embodiment adds downmixing unit on the basis of first embodiment, and the connection of audio effect processing Unit selection is defeated at audio frequency Go out on the branch road of passage, load voice Processing Algorithm.Referring to Fig. 3, the operation principle of this embodiment is: hear on earphone is Through the wet acoustical signal of audio effect processing, the dry acoustical signal of the input of mike is directly passed through through the main road of audio frequency output channel The outside Fructus Mali pumilae equipment of Lightning interface output, and through the branch road input audio mixing of audio frequency output channel after audio effect processing Unit, exports after mixing with accompaniment signal.

So earphone exports wet sound, and outside Fructus Mali pumilae equipment is exported dry sound, it is achieved listen wet record to do.

4th embodiment

This embodiment power amplifier module between described D/A conversion unit and described earphone on the basis of first embodiment, Described power amplifier module includes downmixing unit: combine the signal flow control of corresponding Fig. 2, can realize listening dry record wet；In conjunction with correspondence The signal flow control of Fig. 3, can realize again listening wet record to do.

Power amplifier module that so downmixing unit headset/earphone is intrinsic realizes, and makes that circuit is simple, low cost.

5th embodiment

This embodiment adds the primary sound unit that disappears on the basis of first embodiment, and the primary sound unit that disappears is connected to MFI certification list Between unit and D/A conversion unit, disappear for the audio signal that outside Fructus Mali pumilae equipment is inputted through audio signal input channel Export after primary sound.The primary sound unit that disappears specifically can be disappeared by selecting connection audio effect processing unit on audio input channel, loading Primary sound Processing Algorithm realizes.The operation principle of this embodiment is: is inputted " music " by Lighting interface and inputs to the primary sound that disappears Unit, the primary sound that disappears is exported " accompaniment " by outfan after processing, finally exports to earphone, and what earphone was heard is " accompaniment ".

So hear on earphone is to eliminate in " music " " accompaniment " after primary sound.

Sixth embodiment

This embodiment adds mode selection button on the basis of first embodiment on headset housing, and audio effect processing list Unit is realized by the DSP of headset enclosure interior.Can select, by mode selection button, the audio algorithm that DSP specifically loads, control The mode of operation of DSP.

By mode selection button control DSP load corresponding audio algorithm and increase downmixing unit can be in a product All realize first, second and third and four embodiments and be not restricted to the function of aforementioned four embodiment.So circuit structure is simple, Feature richness, overall low cost.

7th embodiment

This embodiment of Fig. 4 adds one or above Lightning interface on the basis of first embodiment, the most permissible Connect multiple stage Fructus Mali pumilae equipment.Lightning interface is fixedly installed relative to headset main body, or with the form of free end by wire rod with Headset main body electrically connects.

Foregoing, preferred embodiment the most of the present utility model, it is not intended to limit embodiment of the present utility model, Those of ordinary skill in the art, according to central scope of the present utility model and spirit, can carry out corresponding accommodation very easily Or amendment, therefore protection domain of the present utility model should be as the criterion with the protection domain required by claims.
