Abstract
The utility mode relates to a karaoke effector for a universal serial bus (USB) computer. The karaoke effector comprises a USB processing chip, a microphone volume balancing processing circuit, a digital signal processor, a signal input selecting circuit, a voice muting circuit, an accompaniment volume balancing processing circuit, a signal mixing circuit, an output volume control circuit and an input/output automatic control circuit, wherein the microphone volume balancing processing circuit, the digital signal processor, the signal input selecting circuit, the voice muting circuit and the accompaniment volume balancing processing circuit are connected in sequence; and the microphone volume balancing processing circuit, the digital signal processor and the accompaniment volume balancing processing circuit are connected with the signal mixing circuit respectively. When the karaoke effector is used, a plurality of sound sources such as MP3 input, compact disc (CD)/digital video disk (DVD) input or music stored in an external computer can be input optionally, the sound sources can be played independently or matched with voice input of the microphone for karaoke singing, and the voice recording function can be realized.
Description
Technical field
The utility model relates to a kind of USB computer sound recording and/or reproducing apparatus, specifically is a kind of Karaoke effect device.
Background technology
Nowadays along with the raising of rapid economy development, people's cultural life, the card song has become people's fashional consumption, but high price also makes a lot of people not enjoy oneself to heart's content.Along with popularizing of network, the consumer can find us needed many resources to be used on network, comprises card OK accompaniment music etc., and insufficient these resources of utilizing will be very big wastes.
Many softwares that utilize computers to carry out K song have appearred in the market, such as Mike crazy be exactly a computer Karaoke software, it adopts advanced stream media technology, and the internet is brought up in the Karaoke amusement that the dark broad masses of being subjected to like.This software comprises requesting song, the K song, and record, scoring, multiple functions such as match can be made the Karaoke of real one's own family, the home-confined impression of experiencing the karaoke chamber.But computer software is inconvenient to move, need repeat in the time of on changing to other computer to install, and function singleness, can not record, can not accept other accompaniment source of sound input.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can carry out USB with computer and be connected, and can play Karaoka, the USB computer Karaoke effect device of recording, playing back music.
A kind of USB computer Karaoke effect device, it comprises the USB process chip, microphone volume equilibrium treatment circuit, digital signal processor, the signal input selection circuit, the voice circuit disappears, accompaniment volume equilibrium treatment circuit, signal mixed circuit, output volume control circuit and input and output automatic control circuit, microphone volume equilibrium treatment circuit, digital signal processor, the signal input selection circuit, the voice circuit that disappears is connected in turn with accompaniment volume equilibrium treatment circuit, microphone volume equilibrium treatment circuit, digital signal processor is connected with signal mixed circuit respectively with accompaniment volume equilibrium treatment circuit, signal mixed circuit, the output volume control circuit is connected in turn with the input and output automatic control circuit, the signal input selection circuit, the output volume control circuit is connected with the USB process chip respectively with the input and output automatic control circuit, microphone volume equilibrium treatment circuit connects more than one microphone, the USB process chip has USB interface, and the input and output automatic control circuit has output interface.
Preferably, described output volume control circuit connects volume indicator.
Preferably, described signal input selection circuit has MP3 input interface and CD/DVD input interface.
When the utility model used, the USB process chip connected host computer by USB interface, and the output interface of input and output automatic control circuit connects multimedia loudspeaker box/earplug.The signal input selection circuit can select to import multiple source of sound, as the music of storing in MP3 input, CD/DVD input or the external computer, this source of sound both can be play separately, also can fit into capable karaoke with people's vocal input of microphone, can also realize sound-recording function.
