Description

A kind of multi-functional OK a karaoke club OK earphone
Technical field
The present invention relates to a kind of earphone, more particularly, relate to a kind of multi-functional OK a karaoke club OK earphone that is used for multimedia recreation with Kara OK function.
Background technology
Common Headphone device mainly is used in and listens to the music, common Karaoke also is at home theater or sings the Room at KTV and realize, but traditional Caraok device volume all is bigger, and the separate groups mould assembly, generally is made up of mains supply, TV, computer, karaoke machine, power amplifier, loudspeaker, microphone.
Be unfavorable for like this carrying, therefore be subjected to the restriction of objective condition such as volume is big in the use, limited greatly and sung the place that the fan plays Karaoka.
And present mobile phone, PC, audio and video player uses more and more general, price is also more and more lower, because audio and video player can well be realized audio-video playing function, the audio and video player volume is little, portable simultaneously, but audiovisual materials can only be recorded and play to audio and video player, do not have the function of Karaoke.
Common earphone also main application is to listen song and work as headset, all is not have Kara OK function.
The utility model content
The technical problems to be solved in the utility model is, big at above-mentioned existing Caraok device volume, be difficult for carrying, audio and video player does not have the defective of Kara OK function simultaneously, provide a kind of volume with Kara OK function little, portative multi-functional OK a karaoke club OK earphone, it no longer is simple function of listening song that the function that has so just solved the audio and video player Karaoke has also solved common headphones simultaneously, the function of the K that can also sing song.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of multi-functional OK a karaoke club OK earphone, comprise track selecting circuit, bass earphone power amplifier unit and power supply, also comprise common headphones and the first audio frequency input unit of playing Karaoka the earphone change over switch, playing Karaoka reverberation IC and being used for being connected with built-in microphone; The second audio frequency input unit of external audio frequency joint; The audio signal of described first audio frequency input unit and the input of the described second audio frequency input unit is carried out the Frequency mixing processing unit of Frequency mixing processing; And, with the audio output unit of the audio signal output after the Frequency mixing processing.
Further, preferred construction is that the described first audio frequency input unit is provided with switch block.
Further, preferred construction is that described audio output unit also includes second audio output with the audio signal output after the described mixing.
Further, preferred construction is, also includes earphone horn, and described audio output unit connects above-mentioned earphone horn.
Further, preferred construction is that described power supply is a lithium battery.
The beneficial effect that the utility model has been had after having taked technique scheme such as below description:
The first, owing to adopt double-tone input unit and Frequency mixing processing unit frequently, make and the phonetic entry and the accompaniment music of microphone well can be carried out Frequency mixing processing, on media player, realized the function of Karaoke;
The second, because above-mentioned parts all are to be built in earphone inside, thereby realize utilization volume technique effect little, that play Karaoka anywhere or anytime in conjunction with portable media player.
Description of drawings
By coming that below in conjunction with accompanying drawing the utility model is carried out further detailed description, above-mentioned advantage of the present utility model and technique effect will become more obvious.
Fig. 1 is the structural representation of the specific embodiment of the multi-functional OK a karaoke club OK of the utility model earphone;
Fig. 2 is the control structure schematic diagram of the multi-functional OK a karaoke club OK of the utility model earphone.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the specific embodiment of the multi-functional OK a karaoke club OK of the utility model earphone.
As shown in Figure 1, in first preferred embodiment of the multi-functional OK a karaoke club OK of the utility model earphone, described multi-functional OK a karaoke club OK earphone comprises earphone, earphone cord, microphone (microphone), Karaoke reverberation IC, bass earphone power amplifier, and power supply.
The first audio frequency input unit is connected with microphone, and the first audio frequency input unit is used for receiving speech information and voice messaging is sent to the Frequency mixing processing unit; The second audio frequency input unit is used to receive the audio-frequency information of accompaniment and this audio-frequency information is sent to the Frequency mixing processing unit; The Frequency mixing processing unit is used for the audio signal of the first audio frequency input unit and the input of the second audio frequency input unit is carried out Frequency mixing processing; The audio signal output of audio output unit after with Frequency mixing processing.
When this multi-functional OK a karaoke club OK earphone uses as Caraok device, the voice signal that the singer sings by the microphone input, this voice signal is input to the first audio frequency input unit, Ban Zou audio signal is input to the second audio frequency input unit simultaneously, the Frequency mixing processing unit carries out Frequency mixing processing with the voice signal of the first audio frequency input unit and the audio signal of the second audio frequency input unit, the audio signal after the generation mixing; Audio signal after this mixing outputs on the earphone horn by audio output unit, can realize the function of playing Karaoka.
Owing to adopt double-tone input unit and Frequency mixing processing unit frequently, make and the phonetic entry and the accompaniment music of mini microphone well can be carried out Frequency mixing processing, in conjunction with the function that has realized Karaoke on the media player, thereby realize using little, the portable audio and video player of volume to play Karaoka anywhere or anytime.
Fig. 2 is the control structure schematic diagram of the multi-functional OK a karaoke club OK of the utility model earphone.
It has mainly exemplarily shown the setting of various parts of the shell of above-mentioned Karaoke earphone, it only is a concrete structure among the embodiment, those skilled in the art can do distortion arbitrarily at above-mentioned structure under above-mentioned technology enlightenment, do not break away from spirit of the present invention.And, should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
