Abstract
The utility model relates to a karaoke machine used on a mobile terminal, which comprises a microprocessor, a memory, man-machine interaction equipment, an audio frequency processor, a frequency modulation wireless emitter, an audio frequency power amplifier, a left channel loudspeaker and a right channel loudspeaker in concrete realization. When the karaoke machine is used, the sound of a singer is simultaneously input into the audio frequency processor to carry out sound mixing, the song after the sound mixing can be directly output through selecting the loudspeaker, and can also be sent onto the other sound receiving equipment through a wireless audio frequency receiving and sending unit, inconvenience caused by cable transmission can be avoided, and the song can also be stored in a memory card through the sound recording function of the equipment to be appreciated in the future, so the amusement function of karaoke can be realized on the mobile terminal. The utility model has the advantages that the carol can be realized through an earphone microphone, the sound can also be sent onto equipment with the frequency modulation receiving function through the frequency modulation frequency bands for realizing the carol effect at any time in any place, and the utility model can be widely used on the terminal equipment such as a mobile phone, a PDA, a PND and the like, and greatly enhances the amusement function of the mobile terminal.
Description
Technical field
The utility model relates to multimedia technology field, relates in particular to a kind of karaoke machine that is used on the portable terminal.
Background technology
At present, along with people's living standard improves constantly, amusement has become an indispensable part in the daily life, Karaoke is exactly a modal all-ages recreation, though the Karaoke singing-hall has spread all over the streets and lanes in city, not only price is higher but go to the singing-hall to sing, and limited by the place, can not want to sing promptly to sing.
Now the multimedia mobile terminals such as mobile phone of the band Kara OK function on the market are a lot, but along with multimedia technology further develop and perfect, existing product is difficult to satisfy customer requirements, weak point is as follows:
(1) existing karaoke multi-media portable terminal can only simply be eliminated the voice of music formats such as MP3, MP4, can't carry out professional reverberation, has a strong impact on the Karaoke effect;
(2) existing karaoke multi-media portable terminal can only have on earphone or by wired sound is sent on other stereo sets during performance, very inconvenient.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the purpose of this utility model provides a kind of karaoke machine that is used on the portable terminal, can be used on the multiple multimedia mobile terminal, multimedia mobile terminal can be become a specialty Karaoke jukebox, to leave in through the high-fidelity MTV of pretreated multiple form in the storage card, the user can have on headset and sing merrily, and also can be transmitted in the sound equipment of external belt FM reception by frequency modulation and play.
To achieve these goals, the technical solution of the utility model provides a kind of karaoke machine that is used on the portable terminal, comprise microprocessor, memory, human-computer interaction device, audio process, frequency modulation wireless launcher, audio-frequency power amplifier and left and right sound channels loud speaker, described microprocessor comprises control unit and audio coding decoding unit, described human-computer interaction device comprises keyboard, display and microphone.
The audio frequency I/O end of described audio coding decoding unit connects by the audio frequency I/O end of audio-frequency bus with described audio process; The I/O end of described control unit connects by the I/O end of control bus with the control signal of described audio process.
Described keyboard links to each other with described microprocessor, and described display links to each other with described microprocessor, and described microphone interface links to each other with the input of audio process.
The vision signal of the music file that described microprocessor will read from described memory is sent to display and shows, sends described audio process to by audio-frequency bus after voice signal is decoded into background music and original singer's voice signal; Described audio process is sung the voice of receiving partly synthetic with the vocal accompaniment music, and the file transfer after synthetic is saved in the described memory to after the audio coding decoding resume module of described microprocessor.
The audio output of described audio process connects with the audio input end of described audio-frequency power amplifier, and connects with the audio input end of described frequency modulation wireless launcher; Described frequency modulation wireless launcher sends wireless signal and receives for outside FM receiver; The output of the left and right sound channels of described audio-frequency power amplifier connects with the left and right sound channels loud speaker respectively.
The utility model system not only can realize the high-fidelity Karaoke by wired loud speaker or earphone, can also pass through the frequency modulation frequency range, music be sent on the stereo set of any one band FM reception function, realize whenever and wherever possible, want just to sing and sing, satisfy the demands of consumers.
Description of drawings
Fig. 1 is the structured flowchart that is used for the karaoke machine on the portable terminal of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of karaoke machine that is used on the portable terminal described in the utility model, comprise microprocessor, memory, human-computer interaction device, audio process A130, frequency modulation wireless launcher QN8006, audio-frequency power amplifier AW8730 and left and right sound channels loud speaker, microprocessor comprises control unit and audio coding decoding unit, the human-computer interaction device comprises keyboard, display and microphone.
The audio frequency I/O end of the audio coding decoding unit of microprocessor connects with the audio frequency I/O end of audio frequency processor A 130 by audio-frequency bus I2S; The I/O end of the control unit of microprocessor connects with the I/O end of audio frequency processor A 130 by control bus I2C.Keyboard, display is connected with microprocessor, and microphone interface links to each other with the input of audio process.The audio output of audio process A130 connects with the audio input end of audio frequency power amplifier AW8730, and connects with the audio input end of frequency modulation wireless launcher QN8006.The output of the left and right sound channels of audio-frequency power amplifier AW8730 connects with the left and right sound channels loud speaker respectively.
