Abstract
A loudspeaker box comprises a box body. Upper, lower, front, rear, left and right loudspeakers are arranged on the box body. The axes of two adjacent loudspeakers on the box body form a right angle. Supporting devices are arranged on the box body. The loudspeaker box can give out sound waves toward six different directions. The supporting devices of the box body can ensure the sound waves given out by the loudspeaker at the bottom can come out smoothly, thus the large indoor entertainment places can achieve the effect of presence (that is: people have a feeling of being surrounded by sounds) by only needing one loudspeaker. The loudspeaker box is low in cost and simple in installation. In addition, as the upper, lower, front, rear, left and right loudspeakers on the loudspeaker box respectively face the bottom surface, the roof and the surrounding walls, the sound waves in various directions only have one main refracting surface. The direction of propagation of the sound waves after refraction is clear, thus avoiding binaural effect turbidity and ensuring good effect of presence.
Description
Technical field:
The utility model relates to a kind of loudspeaker arrangement, is a kind of employed audio amplifier of large-scale indoor public place of entertainment that is suitable for specifically.
Background technology:
Common audio amplifier comprises casing and loud speaker at present, existing audio amplifier upper speaker towards having only one to be that audio amplifier can only send sound wave towards a direction, a said independent Presence that audio amplifier can not produce need be arranged in a plurality of audio amplifiers a plurality of directions and match and could realize.Such as, most large-scale indoor public places of entertainment all are an audio amplifier respectively to be installed as sound source in four corners in hall, sound is propagated from four corners to place central authorities, the space in whole place is all surrounded by the sound field that these sound sources produced, thereby realization Presence, and use not only cost height of four audio amplifiers, trouble is installed, and audio amplifier is contained in the plane of refraction that the corner has also increased sound wave, be subjected to the loud-speaker surface and the not influence of equal factor of the angle between each plane of refraction of audio amplifier, sound wave passes to the time of each plane of refraction, the sound intensity, phase place is all inequality, the direction of propagation after the sound deflection is relatively more chaotic, is easy to generate phase shift in the hall, is commonly called as " binaural effect " muddiness on specialty, in addition, the sound field that this mode produces also lacks, the sound wave of following both direction makes audio distortions, and Presence is poor.
The utility model content:
The technical problems to be solved in the utility model is, provides a kind of cost low, install simple, the audio amplifier that Presence is good.
The technical solution of the utility model is: comprise casing, that described casing is provided with is upper and lower, six of front, rear, left and right towards loud speaker, the angle on the described casing between adjacent two loud speaker axis is the right angle, described casing is provided with bracing or strutting arrangement.
After adopting said structure, the utlity model has following advantage:
The utility model audio amplifier can send sound wave to six different directions, the sound wave energy that the bracing or strutting arrangement of casing sends the bottom loud speaker spreads out of smoothly, so large-scale indoor public place of entertainment only need an audio amplifier can produce Presence (even the people have a kind of by sound around sensation), cost is low, installs simple.And since six of upper and lower, the front, rear, left and right of audio amplifier towards loud speaker respectively over against the bottom surface, roof and wall all around, like this, the main plane of refraction of all directions sound wave has only one side, the direction of propagation after the sound deflection is clear, can avoid problems such as " binaural effect " muddiness, Presence is good.
As improvement, described casing is a regular hexahedron.
As improving, described bracing or strutting arrangement is a supporting leg again.
Description of drawings:
Accompanying drawing is the structural representation of the utility model audio amplifier;
Shown in the figure: 1, casing; 2, loud speaker; 3, supporting leg.
Embodiment:
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Be the embodiment of the utility model audio amplifier as shown in drawings, comprise casing 1 and six loud speakers 2.
Described casing 1 is a regular hexahedron, upper and lower, six faces in front, rear, left and right of described casing 1 are provided with loud speaker 2, clearly, angle on the casing 1 between in adjacent two loud speakers 2 is the right angle, the supporting leg 3 that is arranged on casing 1 bottom makes between the bottom loud speaker 2 of casing 1 and the ground has one section space so that sound wave energy spreads out of smoothly, like this, audio amplifier just can be up and down, the front, rear, left and right six direction directly sends sound wave.
During use, only need the utility model audio amplifier is placed on the central authorities in hall, four sides of casing 1 face four indoor walls respectively, the loud speaker 2 that is arranged on casing 1 bottom and end face respectively up and down both direction send sound wave, the loud speaker 2 that is arranged on each side is distinguished forward, after, a left side, sound wave is sent on the right side, the main plane of refraction of each sound wave has only one and each sound wave to pass to the time of plane of refraction separately, the sound intensity, phase place is identical, the direction of propagation after each sound deflection is neat, clear, be difficult for taking place phase shift, can avoid problems such as " binaural effect " muddiness, and owing to the utility model audio amplifier can make progress, following both direction sends sound wave, can get rid of sound distortion like this, Presence is good.
The above embodiment is a preferred version, can not regard the restriction to the utility model independent claims as, and the concrete structure of the utility model audio amplifier allows variation.As: casing 1 can also be other shapes such as circle or cuboid; The quantity of casing 1 upper speaker 2 can also be more than six; Or the like.All various variations of being done in the protection range of the utility model independent claims all drop in the protection range of the present utility model.
Claims (3)
1. audio amplifier, comprise casing (1), it is characterized in that: described casing (1) be provided with six of upper and lower, front, rear, left and right towards loud speaker (2), the angle that described casing (1) is gone up between adjacent two loud speakers (2) axis is the right angle, and described casing (1) is provided with bracing or strutting arrangement.
2. audio amplifier according to claim 1 is characterized in that: described casing (1) is a regular hexahedron.
3. audio amplifier according to claim 1 and 2 is characterized in that: described bracing or strutting arrangement is supporting leg (3).
