Abstract
The utility model discloses a multifunction portable kara-ok machine which is provided with a handle convenient for carrying. Circuits of tone shift, the inhibition of the sound volume of the medium frequency band of an audio frequency, wireless frequency modulation emission, am broadcast receiving, etc. are arranged in addition, except the functions of kara-ok vocal accompaniment, sound amplification, reverberation, etc. The playing tones can be shiftted up and down for a plurality of musical intervals by the tone shift circuit so as to adapt to pitches of different singers. The common singing sound which is not in the kara-ok tape can be reduced by the inhibition circuit of the sound volume of the medium frequency band of the audio frequency. The musical sound relatively increases so as to produce the effect of the kara-ok tape. The utility model can be combined with high, medium and low grade acoustic devices for playing music by a wireless frequency modulation emission system, so as to improve the tone quality and the music effect. The utility model also has the functions of singing by two persons at the same time and a radio.
Description
The utility model belongs to the improvement of karaoke machine in the radio electroacoustic techniques.
Karaoke machine is a kind of of a mass character from singing from the recreational electronic apparatus of drilling with music, be generally desktop computer, being suitable for singing-hall or family uses, a kind of portable karaok machine is arranged, it can hand performance, it is unaffected to get around, and can adapt to outdoor use, is particularly suitable for outdoor collective and travels and travel.Because of its volume is little, also is suitable for family and uses.
The portable karaok machine is generally by shell, handgrip, microphone, acoustical generator, magnetic tape record/play sound mechanism, power supply, operation and control device, and forms with the internal circuit that function adapts, and is assembled within the above-mentioned shell.At present portable karaok machine inside partly is made up of echo circuit, power amplifier playback circuit etc. of magnetic tape record/play sound mechanism and circuit, evener, mixing.The Typical Route block diagram as shown in Figure 1.The function of this series products is only limited to karaoke accompaniment, talks to amplifying, echo several functions.
The utility model provides a kind of portable multifunctional karaoke machine of novelty, its objective is expanded functionality, adapts to different levels and occasion and sings needs, improves recreationally, makes the holder obtain multinomial senior consumption effect.
The utility model is to increase new function on above-mentioned conventional portable karaoke machine, increase multiple circuit and corresponding operation control device, its principal character is to increase a kind of circuit such as transposition circuit and to the inhibition circuit of song in the non-Karaoke tape to several specific functions.
The characteristics that increase the transposition circuit are the several intervals of transposition about the raw tape playback tone such as 5 intervals, to adapt to different singers' pitch, particularly can be adapted to amateurish the performance and home entertaining, increase enjoyment.Its Typical Route can be as shown in Figure 2.
Increase to the characteristics that song in the non-Karaoke tape suppresses circuit is: the song in the common tape is suppressed or decay by electronic circuit, outstanding tune music makes the effect of non-OK a karaoke club karaoke tape generation OK a karaoke club karaoke tape.Just can make common tape " Karaokeization ", carry out karaoke, enlarge Karaoke tape pool capacity virtually.Its Typical Route as shown in Figure 3.
On above-mentioned improved basis, the portable multifunctional karaoke machine can also increase the frequency modulation wireless transmitting system, make its can with the online playback of medium and high-grade stereo set, improve tonequality and music effect and appreciate and professional karaoke needs to satisfy, its Typical Route can be as shown in Figure 4.
In addition, can increase and add formula external microphone jack, rather than interrupt the formula external microphone usually, just can two people unite simultaneously and sing, enrich singing form and temperament and interest.Its Typical Route can be as shown in Figure 5.
Increase the circuit that receives medium wave band amplitude modulation broadcasting program of radio station, can be used as radio and use.Its Typical Route as shown in Figure 6.
The utility model has the advantages that significantly, cost increases few, on functions of use, an enterprising step expands on the function basis of original karaoke accompaniment machine, makes the singer obtain more satisfying:
1. transposition function has increased performance enjoyment to adapt to the amateurish pitch of singing.
2. common tape " Karaokeization " function has enlarged Qu Ku, has reduced investment cost, particularly average family is had practical significance.
3. frequency modulation emission and the online player function of medium and high-grade sound equipment adapt to the different levels needs, obtain senior consumption effect.
4. other adds formula external microphone and radio function as increase.All make this machine a tractor serves several purposes, enlarged function, increased recreational.
A kind of possibility participate-reform circuit block diagram of the present utility model as shown in Figure 7.
Claims (4)
1, a kind of portable multifunctional karaoke machine is made up of shell, handle, microphone, acoustical generator, magnetic tape sound reproducer structure, power circuit and operation and control device and inner function circuit, inner function circuit has playback circuit, evener, mixing echo circuit, power amplifier playback circuit, and its principal character is that internal circuit has the transposition circuit and to the inhibition circuit of the Mid Frequency volume of audio frequency.
2, karaoke machine as claimed in claim 1 is characterized in that having increased the frequency modulation radio transmitter.
3, karaoke machine as claimed in claim 1 or 2 is characterized in that having increased and adds formula external microphone jack circuit.
