Abstract
The utility model provides a computer with built-in karaoke function. The computer with the built-in karaoke function comprises a computer, a karaoke circuit module and an earphone power amplifier. The karaoke circuit module is in bidirectional communication connection with the computer. An output end of the karaoke circuit module is connected with the earphone power amplifier. The karaoke circuit module comprises multiple AD (Analogue to Digital) converters, a digital signal processor and a DA (Digital to Analogue) converter. According to the utility model, professional effects such as treatment of microphone echo, treatment of reverberation, balancing treatment, voltage limiting treatment and howling inhibiting treatment can be realized by adding the built-in karaoke function module in the computer, so that the computer has the karaoke function, thereby greatly enhancing the market competitiveness of the computer in karaoke products.
Description
Technical field
The utility model relates to the computer field, relates in particular to a kind of computer of built-in karaoke function.
Background technology
At present, the standard audio in the computer is configured to built-in microphone, a pair of Microspeaker and the earphone socket below the frequency band 8KHz, and earphone socket has also comprised an external microphone, can connect the microphone/ear speaker device of one.
But this configuration is because the restriction of hardware condition; The microphone part can not realize echo (ECHO), reverberation (REV) balanced (EQ) and other specialty type effect; Even increase these functional effects through inner software processes; Because there are defectives such as frequency response is narrow, dynamically little, background noise is big in quality, the configurable limit of microphone part itself, still can't satisfy high-quality Karaoke amusement requirement.
Summary of the invention
The purpose of the utility model is to provide a kind of computer of built-in karaoke function, plays the effect of Karaoke audio, satisfies the needs of home entertaining.
The purpose of the utility model realizes through following technical scheme.
A kind of computer of built-in karaoke function comprises: computer, Karaoke circuit module and earphone power amplifier; Said Karaoke circuit module is set up two-way communication with computer and is connected, and the output terminal of said Karaoke circuit module links to each other with the earphone power amplifier, and said Karaoke circuit module comprises multi-channel A converter, digital signal processor and DA converter.
Preferably, said earphone power amplifier is a D class earphone power amplifier, and it comprises 2 covers or the above earphone accessory power outlet configuration of 2 covers.
Preferably, also comprise single-chip microcomputer, said single-chip microcomputer is used for control Karaoke circuit module work and establishes a communications link with computer.
Preferably, said computer is panel computer or laptop computer.
The utility model compared with prior art; Beneficial effect is: the utility model is through increasing a built-in karaoke functional module in computer; Can realize microphone echo processing, reverberation processing, equilibrium treatment, the processing of pressure limit, the specialty type effects such as suppressing processing of uttering long and high-pitched sounds; Make computer have Kara OK function, promoted the market competitiveness of computer product greatly in the Karaoke segmentation.
Description of drawings
Fig. 1 is the computer theory diagram of the utility model built-in karaoke function.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.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.
See also shown in Figure 1ly, the computer of the utility model built-in karaoke function comprises: panel computer 1, single-chip microcomputer 2, Karaoke circuit module 3, earphone power amplifier 4; Karaoke circuit module 3 is set up two-way communication with single-chip microcomputer 2 and panel computer 1 respectively and is connected, and single-chip microcomputer 2 is used for 3 work of control Karaoke circuit module and communicates by letter with panel computer 1 foundation, and the output terminal of Karaoke circuit module 3 links to each other with earphone power amplifier 4.Said computer 1 comprises panel computer and laptop computer.
Wherein, Karaoke circuit module 3 comprises multi-channel A converter, digital signal processor (DSP), DA converter, 2 tunnel (or more than 2 tunnel) microphones (1,2) input; Through AD converter separately; With analog-signal transitions is digital signal, is input to digital signal processor (DSP), accomplishes microphone and presses processing such as limit processing, equilibrium treatment, time-delay echo, reverberation processing, the inhibition of uttering long and high-pitched sounds; Simultaneously; The audio output signal of computer system also gets into DSP through AD converter (if simulating signal) or direct (if digital signal); Disappear song, rising-falling tone, equilibrium, pressure limit, etc. processing such as loudness back mix with microphone signal and export the DA converter to, be simulating signal with digital signal transition, output to earphone power amplifier or direct failing and get back to computer; Earphone power amplifier lug machine (1,2) output.
Wherein, the audio output signal of computer system is sent computer system back to and is done the recording processing after DSP handles.
In the utility model, the earphone power amplifier is a D class earphone power amplifier, and it comprises 2 covers or the above earphone accessory power outlet configuration of 2 covers.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
