The invention discloses a karaoke system for a mobile terminal. During specific implementation, the karaoke system comprises a microprocessor, a storage, man-machine interaction equipment, an audio processor, a frequency modulation wireless transmitter, an audio power amplifier, a left channel loudspeaker and a right channel loudspeaker. During use, sounds of singers are simultaneously input into the audio processor for mixing, the mixed singing sound can be directly output through the loudspeakers and can be transmitted to another sound receiving equipment through a wireless audio transceiving unit, inconvenience brought by wired transmission is avoided, and the sound can be stored in a storage card for later appreciation through a recording function of the equipment; therefore, an entertainment function of karaoke is realized at the mobile terminal. The karaoke system can be used for caroling through an earphone and transmitting the sound to equipment with a frequency modulation receiving function through a frequency modulation frequency range, achieves an effect of caroling at any time in any place, can be widely applied to mobile phones, personal digital assistants (PDAs), portable navigation devices (PNDs) and other terminal equipment, and greatly improves the entertainment function of the mobile terminal.
Description
technical field [0001] The invention relates to the field of multimedia technology, in particular to a karaoke system for mobile terminals. Background technique [0002] At present, with the continuous improvement of the quality of life of the people, entertainment has become an indispensable part of daily life. Karaoke is one of the most common recreational activities suitable for all ages. Singing in karaoke halls is not only expensive, but also limited by the venue, you can't sing as you want. [0003] There are many multimedia mobile terminals such as mobile phones with karaoke functions on the market now, but along with the further development and perfection of multimedia technology, existing products are difficult to meet user requirements, and the shortcomings are as follows: [0004] (1) Existing karaoke multimedia mobile terminals can only simply eliminate human voices in music formats such as MP3 and MP4, and cannot perform professional reverberation, which seriou...
