Description
Technical field
The utility model relates to audio amplifier, particularly the bi-component audio amplifier.
Background technology
The high low pitch joint of common audio amplifier, usefulness be the frequency change that RC or lc circuit come detection system in the regulating circuit, to satisfy the sense of hearing to the requirement of tone color or reach certain effect.The existence of LC element is subjected to the influence of its feature in the circuit, may cause " hangover " distortion and phase-shift distortion, the especially low-frequency range of music signal, is easy to make pronunciation muddy.Unsuitable high low pitch joint has very havoc to the effect of sound equipment: such as the sound muddiness: the reason that generally causes this situation is because the following frequency range lifting of 500HZ is excessive, causes the sound of medium-high frequency section to be influenced by strong excessively bass, and causes intermodulation distortion; Sound is stuffy, and is not loud: generally be excessive or promote excessively below the 2000HZ because of decay more than the 2000HZ, and cause the result that the level of medium-high frequency section reduces; In addition, also have the sound obfuscation, sound is short-tempered, sound is thin, sound is loose, drift, lack telepresenc, problems such as sound hardens, drying.
In the music signal, the alt composition accounts for important status, and the sense of direction of sound, bright sense, color and luster sense are all by the alt decision, and a high pitch loudspeaker is when showing above-mentioned high pitch feature, and is often unable to do what one wishes, do not reach good effect; The air whole process of a woofer promotion is limited, and when low frequency needed dive dark, the sympathetic deficiency of the amount of low frequency in order to address this problem, just needed increasing to promote the volume of air.Obtain bigger promotion volume of air and can use the large scale woofer.When using the large scale woofer, because its Vibration Box quality is big, its inertia is just big, causes transient distortion big, because the Vibration Box area is big, just is easy to generating box and splits phenomenon.
The utility model content
In order to address the above problem, the utility model provides a kind of bi-component audio amplifier.
The technical scheme that its technical problem that solves the utility model adopts is as follows: the bi-component audio amplifier, and it comprises two high pitch loudspeakers, two woofers, two frequency dividers, eight binding posts and casing, dividing plate, paraphase hole; By dividing plate 1 audio amplifier is divided into two parts at the audio amplifier middle part, just two relatively independent tone chambers; The plate of dividing plate 1 for tilting, the angle between dividing plate 1 and the top and bottom is the 1-89 degree; Angle optimized angle between dividing plate 1 and the top and bottom is 10-20 degree or 70-85 degree; Dividing plate 1 and dividing plate 11 are divided into casing can be for the accommodation space of the various unit that amplify of installing, the be placed in both sides of dividing plate 1 of high pitch loudspeaker 7 and high pitch loudspeaker 8; The be placed in both sides of dividing plate 1 of woofer 3 woofers 4.
The panel layout of bi-component audio amplifier can be varied, as Fig. 3, Fig. 5, Fig. 6, Fig. 7, shown in structure.
The panel layout of optimum efficiency is a dumbbell type as shown in Figure 3, respectively is up and down a woofer, Yi Bian the centre is two high pitch loudspeakers, vertically arranges, and another side is two paraphase holes, vertically arranges.
The beneficial effects of the utility model are:
The bi-component audio amplifier is divided into two relatively independent tone chambers by swash plate with casing, amplify element when work, by mutual cooperation and influence, cause the expansion of sound channel, to bring into play the effect of keynote to greatest extent, (keynote is the sound that loud speaker sends, the sound of secondary sound for sending by casing resonance to reduce secondary sound.) the bi-component audio amplifier, obtained effect is not two independent audio amplifiers to be put together just can obtain.Two independent audio amplifiers are worked simultaneously, have just strengthened the sphere of action of volume and sound.And the bi-component audio amplifier has greatly improved at everyways such as sound qualities.
For conventional audio amplifier, generally has only each one of high pitch loudspeaker and woofer, serving as high pitch respectively resets and replaying bass, then finish for middle pitch by two cooperations, when in the bi-component audio amplifier during with two bass, alt amount sense is owing to the enhancing of bass composition weakens, and increase a high pitch loudspeaker this moment again, can improve the amount sense of middle and high sound.When big acoustic pressure was play, because the high pitch audio frequency generally has only 20-30 watt, it is limited that it bears power, long-time big down dynamic, cause the burning high pitch easily, after adopting two high pitch loudspeakers, alt acoustic pressure shellfish just is issued to requirement than being easier at high-power, big acoustic pressure shellfish state.In the music signal, the alt composition accounts for important status, the sense of direction of sound, bright sense, color and luster sense are all determined by alt, a high pitch loudspeaker is when showing above-mentioned high pitch feature, often unable to do what one wishes, do not reach good effect, two common cooperations of high pitch loudspeaker just can address the above problem.
The air whole process of a woofer promotion is limited, and when low frequency needed dive dark, the sympathetic deficiency of the amount of low frequency in order to address this problem, just needed increasing to promote the volume of air.Obtain bigger promotion volume of air and can use the large scale woofer, also can use two woofers.When using the large scale woofer, because its Vibration Box quality is big, its inertia is just big, causes transient distortion big, because the Vibration Box area is also big, just generating box splits phenomenon easily; When using two woofer, because two common cooperations promote the bigger purpose of volume of air so only need small-bore woofer just can reach, this moment, single loud speaker bore was little, the Vibration Box light weight, its transient response, Q value etc. all is better than the heavy caliber loud speaker.Audio amplifier wants good tone color, needs the intermediate frequency concentration of energy, has only small-bore woofer just can cover intermediate-frequency section.
When two audio amplifiers are worked simultaneously together, though energy can increase, but the operating power of loud speaker is constant in every audio amplifier, so shortcoming in the time of not only can not solving above-mentioned single speaker operation, on the contrary because the increasing of energy, its audio distortions phenomenon is exaggerated, causes more serious " hangover " distortion and phase-shift distortion.
So the bi-component audio amplifier can reach the effect of bringing into play keynote to greatest extent, sound quality is good: sound is plentiful, and levels are rich is pure and not sharp, and is thick and heavy and not stiff, deep and not muddy, soft and moist and not empty soft, vivaciously and not light, broad and not loose.Extensive again sound also can admit, and is open, receives to such an extent that live, and also can pick up at tiny sound, reads accurately, walks straight.Can satisfy the demand of people to the sound high-fidelity.
