Description

The PC cartridge device of playing Karaoka

The utility model relates to electronic musical instrument, specifically is that a kind of host computer of planting is reserved the Karaoke cartridge device on the soft disc player groove seat.

Common Caraok device, major part are independent enforcement, that is to say the microphone input equipment with single group, it can be used with Video Recorder or with radio-tape recorder, also have with video disc player to be used.These structure major parts are separate type, and all are huger structures, can't be directly and the computer use of integrating.At present, PC (individual) computer is widely popular, and is known as and is multimedia, the CD-ROM device of existing high power speed occurs, cooperate sound blaster and audio-visual card and relevant software, can on senior screen, show than the better effect of TV, so, gone on the CD-ROM device of many vocal accompaniment shadow bands shows more, but all can only listen, can't make up playback with it, and, it is also bigger, not really suitable to connect vocal accompany unit.

The purpose of this utility model is to provide the PC Karaoke cartridge device on a kind of soft disc player groove of 1.22 or 1.44MB seat that is inserted in host computer, to realize that Caraok device and computer integrate, utilize the PC computer to carry out controllable solo, chorus and antiphonal singing, or the output of the vocal accompaniment sound audio mixing of realization and video disc.

The utility model of realizing above-mentioned purpose is similar to general Caraok device, consist predominantly of a shell, one panel and interlock circuit, circuit is arranged in the shell, termination is with panel before the shell, panel is provided with and joins with interlock circuit and a microphone input end socket independently mutually, and a pair of sound volume button, characteristics of the present utility model are, shell is made with metal material, to intercept electronic interferences, and make the physical dimension of this metal shell consistent, can be easily the utility model be planted on the soft disc player position of reserving in the host computer with the soft disc player bulk of host computer; Simultaneously, also be provided with an echo button on the panel, be connected to the treatment circuit of an ES566030 echo microprocessor in the circuit in microphone expander circuit output end, the rear of shell is provided with the power supply of computer three kinds of joints that join, link to each other with left and right sides loudspeaker and CD-ROM device.The PC Karaoke cartridge device of structure like this, the place, soft disc player space that in host computer that it is planted, reserves, and after making its circuit (that is the electric connection at metal shell rear) and 5 volts of power supplys of computer, left and right loudspeaker and CD-ROM device being connected, the recreation of can on the PC computer, playing Karaoka.

Outstanding advantage of the present utility model is that Caraok device can be integrated with computer at an easy rate.This card box Caraok device is planted behind the soft disc player position of reserving in the PC host computer, can directly utilize the power supply of computer, has both saved external power supply, more saved the space, the recreation of can on the PC computer, playing Karaoka easily; And wave volume can be controlled respectively, and echo effect can be adjusted, and also can realize exporting from the vocal accompaniment sound audio mixing of singing with video disc, obtains to sing preferably entertainment effect.

Description of drawings:

Fig. 1 is a stereographic map of the present utility model.

Fig. 2 is user mode figure of the present utility model.

Fig. 3 is the circuit block diagram of the utility model.

Fig. 4 is the physical circuit figure of a preferred embodiment of the utility model.

Embodiment of the present utility model as shown in drawings.Below in conjunction with drawings and Examples the utility model is described specifically.

Seen that by Fig. 1 the utility model includes a metal shell that is square 1, the physical dimension of this metal shell is consistent with the bulk of the soft disc player of host computer.The front end of this metal shell 1 is a panel 10, and panel is provided with independently a microphone input end socket 11,12 and an a pair of sound volume button 13,14 and an echo button 15; The inside of metal shell 1 is provided with circuit such as expander 17,18, echo microprocessor 16, working storage 19,22, silencer 24,25 and quiet controller 23 as shown in Figure 3, Figure 4, and adopting known ES56030 microprocessor in the present embodiment is echo microprocessor 16; The rear of metal shell 1 is provided with: a joint that joins with 5 volts of power supplys of computer, a link that can be connected with left and right loudspeaker and a input end to link to each other with the volume output of CD-ROM device.Sing sound and import via microphone, by loudspeaker output, its have two independently input end socket 11,12 enable to sing a solo or chorus.After the utility model disposes the input end that links to each other with the volume output of CD-ROM device, the music of CD-ROM device can be exported with the music audio mixing of microphone, or music is exported separately.Figure 2 shows that the whole plant of the utility model goes into the state at the places, soft disc player 21 space that reserve in the host computer 2, represent among the figure that the utility model can be made into large and small two kinds of specifications, to adapt to large and small two kinds of soft disc player positions.

See by circuit block diagram shown in Figure 3 and detailed circuit diagram shown in Figure 4, in the present embodiment, after microphone is inserted by socket 11 or 12, after volume is adjusted button 13 or 14, divide by microphone expander 17 or 18 and amplify signal, again with after setting through echo button 15, through numerical digit echo microprocessor 16 (this microprocessor promptly is the described wafer ES56030 of epimere), signal exports working storage 19 after treatment to, 22 and silencer 24,25, silencer 24,25 are subjected to the operation of quiet controller 23, to loudspeaker, and output terminal is exported with the sound audio mixing of microphone input for the music of input CD CD-ROM device by the output terminal output signal.
