Abstract
The utility model relates to an omnibearing sound box which comprises a loudspeaker and a box body. The utility model is characterized in that the bass loudspeaker is arranged at the top of the box body; the upper part of the bass loudspeaker is also provided with one small loudspeaker or two small loudspeakers; the upper part of each loudspeaker is provided with a sound reflector; the small loudspeaker and the sound reflector are positioned on the box body by a support frame. The utility model really realizes the effect that various sound music instruments on site emit sound from various directions, and a listener at any position can exactly distinguish positions where various music instruments are positioned.
Description
The utility model relates to a kind of comprehensive audio amplifier.
As everyone knows, its loud speaker of existing audio amplifier all is installed in the side of casing, effective azimuth that sound wave transmits is about 120 °, also promptly in this scope, can listen to more clear effects,sound, and in the stereo sound field that forms by left and right acoustic channels, can only be on the center line of left and right sides audio amplifier, just can listen to the clearly demarcated effects,sound in various musical instruments orientation, but if depart from this center line, but can only hear the sound that the close together audio amplifier is sent, can't differentiate musical instrument butt position really, and not have tangible stereoeffect, moreover the wide sound field of two audio amplifier constructions is obviously shunk.How to reproduce spot effect, become the difficult problem of current sound equipment industry.
The purpose of this utility model is a kind of comprehensive audio amplifier that can send the sound in 360 ° of angles of design.
Task of the present utility model is achieved in that the comprehensive audio amplifier of being made up of loud speaker and casing, it is characterized in that woofer is installed in the top of casing, above woofer, also be provided with one to two little loud speaker, and be equipped with sound baffle above each loud speaker, little loud speaker and sound baffle are positioned on the casing by support.The utility model faithful reappearance the effect of the comprehensive pronunciation of on-the-spot various sound musical instrument, make and listen hearer what position in office, all can accurately tell the position at various musical instruments place.We are at the concert scene, no matter on any position, all can tell various musical instrument sent on the stage the sound and the orientation at place, trace it to its cause is that the sound wave that various musical instrument sends all becomes comprehensive radiation, and acoustic wave segment reflects by things such as stage backgrounds, and we hear that at the scene sound is exactly the compound voice of direct sound wave and reflective sound wave in fact.
The utlity model has modern design, can build comprehensive sound field, reappear the effect of the comprehensive pronunciation of various musical instruments,, can simulate the stage sight, listen to clearly demarcated clear effects,sound if the nearly the foot of a wall that leans on is placed.
Below in conjunction with concrete legend the utility model is described further:
Accompanying drawing is a structural representation of the present utility model
With reference to accompanying drawing, comprehensive audio amplifier is made up of loud speaker 1 and casing 2, and its medium and low spectrum loudspeaker 1 is installed in the top of casing 2, also is provided with one to two little loud speaker above woofer 1, promptly high pitch or a high pitch and a Squawker are formed two divided-frequency or three frequency division audio amplifier; Be equipped with sound baffle 3 above each loud speaker 1, little loud speaker 11 and sound baffle 3 are positioned on the casing 2 by support 4; 3 one-tenth of sound baffles are horn-like, the coniform and bowl-shape protection range that all belongs to this patent; Little loud speaker 11 above sound baffle 3 is positioned at reflector-horns mouth 31 places, also be the horn mouth place of the Squawker reflector that is contained in woofer, and high pitch promptly is contained on the middle pitch reflector.2 one-tenth cylindrical structures of casing, integral rigidity is better, is difficult for producing case and shakes, and influences tonequality.Can wrap in the support periphery and to be provided with Air Filter.
