Description
Technical field
The utility model belongs to audio amplifier application field, and especially a kind of to be used for larger space, relatively high power is exported either
The audio amplifier used during large-scale performance.
Background technology
Audio amplifier is the terminal of whole sound system, and audio electric energy is converted into corresponding acoustic energy by it when acting on, and its spoke
It is mapped to certain space.
Audio amplifier is the extremely important part of sound system, because it is responsible for all that true reduction nature is sent
Sound, we allow more people to hear and receive by sound to be expressed, and technically key is exactly the frequency range meaning culvert of sound
The scope of lid nature sound, sensitivity meaning is exactly the definition of sound, and acoustic pressure power meaning is exactly the size of sound, right
The sound that nature is sent accomplishes the ability really reduced.
Because human ear exactly evaluates the subjective feeling of sound the most important standard of a sound system tonequality quality, because
This, it is believed that the height of sound box system performance plays key effect to sound quality.
Sound is broadly divided into high pitch, middle pitch, bass and subwoofer, and the high pitch and bass are from the same position of sound source
Put and send.The audio amplifier used at present, takes split type, i.e., one or more alt casings and it is one or more in it is low
Sound box bodies, high pitch, middle pitch, bass and subwoofer are to be diffused sound by different casings when actual use, are made at present
Bass casing in, occurs that bass can not deteriorated quickly through overcompression, bass scatters and disappears rapidly, causes low in actual use
Sound is weak and feeble, or bass hangover, it is impossible to the strength sense of expression required for correct expression sound, it is impossible to correct precisely expression sound
Sound tone color to be expressed.
Sound is broadly divided into high pitch, middle pitch, bass and subwoofer, and the high pitch and bass are from the same position of sound source
Put and send.The audio amplifier used at present, takes split type, i.e., one or more alt casings and it is one or more in it is low
Sound box bodies, high pitch, middle pitch, bass and subwoofer are to be diffused sound by different casings when actual use, are made at present
Bass casing in, the yield equilibrium of bass is difficult to precisely effective unified management in use, and scattering and disappearing for bass is weak and feeble
And hangover, it is difficult to which the strength sense of expression required for controlling expression sound, above mentioned problem is the problem of wishing to solve during performing.
Therefore, a kind of new bass casing, correctly can precisely express sound, prevent bass to scatter and disappear rapidly, it is to avoid bass is weak and feeble,
The casing of the phenomenon of bass hangover is suggested.
In addition, for current this split type audio amplifier, being also unfavorable for the use of large-scale performance.
Current performance audio amplifier is mostly linear array, is that bass individually matches by the superposition of multiple small-power audio amplifiers, high-power and
To improve acoustic pressure power by increasing the quantity of audio amplifier in the case of Larger Dynamic, with audio amplifier quantity increase full-range cabinet and
Woofer can not acoustically accomplish effective balance and uniformly, it is difficult to effectively that bass and full range is unified balanced, big
Live performance, can not also accomplish that sound is unified balanced even if professional tuning personnel in face of the small-power audio amplifier of substantial amounts.Therefore,
A kind of integrated box, and it is applicable large-scale performance place, it is adaptable to the audio amplifier of complex environment is suggested.
