Case market demand to some extent just in this respect is described, and this product has been realized quadraphony audio amplifier etc. with simpler and clearer way
Product that can reach with inaccessible effect.
(3) summary of the invention: the utility model passes through the time-delay reverberation integrated circuit of a M65831 and combining of audio amplifier, and specially
Be the control circuit that foregoing circuit designs, solved the time-delay reverberation of voice signal and the technical problem of control, thereby
On the basis of common double sound channel audio amplifier, add one again, like this, be full of the wonderful of ten thousand dimension depth feelings heavily through the signal of time-delay
Music is seemingly from different orientation, and different angles transmit, and whole healthy picture is surrounded by music, if the hearer closes eyes,
Even the hand that can feel oneself can touch music, and the user can be according to the LED on personal like and the control circuit board
The time-delay length that shows on the display circuit is followed one's inclinations and is regulated time-delay length by being arranged on two knobs on the Loudspeaker panel,
Allow Music Appreciation enter arbitrary brand-new boundary; And utilize the principle of interference of sound wave, effectively reduced noise
To the bad vibration of ear-drum, make for good health and use ear, the useful life of prolonged human ear.Be specially adapted to home audio,
Stereo set such as automobile audio and computer stereo.
(4) description of drawings: as shown in drawings, Fig. 1 always schemes for audio amplifier, and Fig. 2, Fig. 3 are respectively among Fig. 1 and annotate " time-delay reverberation
Circuit " and " control circuit " detail drawing, the direct current electric wire that comes from the audio amplifier general supply connects the vdd port to the time-delay reverberation circuit
Reach control circuit and power respectively, the In port that left and right sides voice-grade channel meets M65831 separately enters prolonging in the audio amplifier of the left and right sides
The time reverberation circuit, this circuit is responsible for and will be defeated by the audio amplifier loud speaker from the Out port after the Audio Signal Processing of the left and right sides, about
After line merged, the ground wire from lead refluxed, the switch 4,5 of the time-delay reverberation circuit M65831 in the audio amplifier of the left and right sides,
6,7 respectively taps merge, and in Fig. 3, insert the Q1 of C4526 respectively, Q2, Q3, the Q4 port is by as among Fig. 3
The unified regulation and control of control circuit.As shown in Figure 3 in the accompanying drawing, the control knob A of control circuit is that time-delay length increases
Key, B then are to reduce key.
(5) embodiment: audio amplifier general supply place establishes three supply lines than existing audio amplifier more, in order to two in the audio amplifier of the left and right sides
Time-delay reverberation circuit and a control circuit power supply.Supply lines meets M65831 and C4526 after entering the operating circuit part
The vdd port to the power supply of this integrated circuit, vcc is from original earplug line current circuit ground connection in the negative pole outlet; Left and right sides sound
Frequently signal circuit then inserts the M65831 operating circuit from the In port, raises one's voice with audio amplifier as usual from outlet Out then
Device is connected.Like this, left and right sound track signals respectively is divided into two, and wherein one keep certain time difference with another, after mixing, export audio amplifier loudspeaker plays (above layout the right and left is identical) jointly to.For guaranteeing the consistency of both sides sound equipment, special time difference control circuit with both sides unites two into one: the switch 4 of the time-delay reverberation circuit M65831 in the audio amplifier of the left and right sides, 5,6,7 tap merging respectively, and in Fig. 3 the Q1 of the CA526 of access control circuit respectively, Q2, Q3, Q4 port, this time difference can be according to the time-delay length and the personal like that show on the LED display circuit on the control circuit board, by by as being arranged on the unified regulation and control of following one's inclinations of two knobs on the Loudspeaker panel among Fig. 3.As shown in Figure 3 in the accompanying drawing, the control knob A of control circuit is that time-delay length increases key, and B reduces key.Concrete time-delay length (on the point type LED display circuit of the CD4514 in Fig. 3 demonstration being arranged) as shown in the table, L wherein, H is by button A among Fig. 3, and B is reduced to the plus-minus regulation and control.Table when 1) DELAYTIME annotates
(kHz) fs: sampling frequency (KHZ)
Td: time-delay length (millisecond) detailed circuit, the mark of situations such as element model and each circuit required voltage, as shown in drawings.Can be by on the basis of said apparatus, adding the time-delay reverberation again, promptly between the Out of first reverberation circuit M65831 that delays time end and audio amplifier loud speaker, one or more identical time-delay reverberation circuits are set, obtain increasing to triple even more sound equipment, reach the effect of " ten thousand dimensions ".Obtain stronger depth feelings as desire, then Zui Jia time difference set point should be in greater than among zero the several minimum shelves, and the depth feelings of this moment is the most lively: obtain music composition for two or more effect as desire, then Zui Jia time difference set point should be on the bigger gear.When required operating voltage of part operating circuit and supply voltage are not inconsistent, before entering circuit, electric current installs transformer additional, to satisfy its voltage needs.Best and the audio amplifier loud speaker close installation of time-delay reverberation circuit, to help guaranteeing tonequality and wiring, the set positions of control circuit need consider that then user's requirement depends on the circumstances: family and automobile audio can merge with the master control panel, and computer sound box can be directly arranged on the comparatively convenient position attractive in appearance of casing.Be exactly to realize best way of the present utility model in sum.
