Abstract
The utility model discloses a kind of cambered surface directional sound, the loudspeaker comprising sound box, audio amplifier facing and be arranged in sound box, described loudspeaker comprise at least two, described loudspeaker are arc surfaced arrangement, and the radius of described cambered surface is the distance of people's ear of loudspeaker and required alignment regions.The utility model structure is simple, and easy to use, the loudspeaker arranged by cambered surface, can reach the effect of sound orientation, and can by different radians, the setting of the loudspeaker of varying number, can reach different poly-audio fruits, have very strong practicality.
Description
Technical field
the present invention relates to a kind of audio amplifier, particularly a kind of cambered surface directional sound.
Background technology
audio amplifier all can be used in current various large-scale place at home and abroad, such as exhibition, museum etc., such as can be divided into multiple venue in museum, such as history shop, odeum, non-something lost shop, digital shop etc., all need audio amplifier to be installed to carry out instructor in broadcasting in each venue, carry out the explanation of some culture, but be all open between each venue, propagation between sound can interference mutually, the phenomenon such as easily cause sound unclear, and therefore designing a kind of audio amplifier can the demand of volume, again can non-interference, seem particularly necessary.
Summary of the invention
The object of the invention is to overcome the problems referred to above, the cambered surface directional sound that a kind of directional effect is good is provided.
For achieving the above object, the method that the present invention adopts is: a kind of cambered surface directional sound, the loudspeaker comprising sound box, audio amplifier facing and be arranged in sound box, described loudspeaker comprise at least two, described loudspeaker are arc surfaced arrangement, and the radius of described cambered surface is the distance of people's ear of loudspeaker and required alignment regions.
As a modification of the present invention, described sound box is arc surfaced, and described loudspeaker are arranged on the casing of described arc surfaced.
As a modification of the present invention, described sound box is camber line rectangular shaped post shape, and loudspeaker are carried out arc surfaced arrangement by support by its inside.
Beneficial effect:
Structure of the present invention is simple, and easy to use, the loudspeaker arranged by cambered surface, can reach the effect of sound orientation, and can by different radians, the setting of the loudspeaker of varying number, can reach different poly-audio fruits, have very strong practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiments of the invention 1;
Fig. 2 is the structural representation of embodiments of the invention 2;
Fig. 3 is the structural representation of the cambered surface directional sound with 4 loudspeaker;
Fig. 4 is the structural representation of the cambered surface directional sound with 16 loudspeaker;
Fig. 5 is the structural representation of the cambered surface directional sound with 64 loudspeaker.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, the present embodiment is implemented under premised on technical solution of the present invention, should understand these embodiments and only be not used in for illustration of the present invention and limit the scope of the invention.
Embodiment 1:
A kind of cambered surface directional sound as shown in Figure 1, the loudspeaker 22 comprising sound box 11, audio amplifier facing 33 and be arranged in sound box 11, loudspeaker 22 comprise 4*4 and have 16 altogether, sound box 11 is arc surfaced, loudspeaker 22 are arranged on the casing of described arc surfaced, and the radius of described cambered surface is the distance of people's ear of loudspeaker and required alignment regions.
Embodiment 2:
A kind of cambered surface directional sound as shown in Figure 2, the loudspeaker 4 comprising sound box 3, audio amplifier facing 1 and be arranged in sound box 3, described loudspeaker 4 comprise 4*4 and have 16 altogether, sound box 3 is camber line rectangular shaped post shape, loudspeaker 4 are carried out the arrangement of arc surfaced by its inside by support 2, the radius of described cambered surface is the distance of people's ear of loudspeaker and required alignment regions.
Just in conjunction with concrete mounting structure, the present invention is further illustrated below, as shown in Figure 3-Figure 5, it is a room, the furred ceiling in room is provided with a cambered surface directional sound, during installation, the circle centre position of the cambered surface of cambered surface directional sound is aimed at the Ren Erchu needing directed transaudient region, determine the radian of cambered surface audio amplifier to the distance of cambered surface audio amplifier according to people's ear place, as shown in Figure 3, this cambered surface audio amplifier comprises 2*2 and has 4 loudspeaker altogether, the watt level of loudspeaker is gone out according to the formulae discovery of the decay of sound wave transmission, because the normal hearing of people's ear is at 65-70db, the sound that we set alignment regions needs is 65db, the power of the loudspeaker on the cambered surface audio amplifier so just can calculated according to distance, due to the loudspeaker often doubled, sound can increase 3db, so according to the directional sound having 4 loudspeaker in Fig. 3, be 65db at the sound of alignment regions, can reduce by 6 db around alignment regions is 59db.
As shown in Figure 4, this cambered surface audio amplifier comprises 4*4 and has 16 loudspeaker altogether, the watt level of loudspeaker is gone out according to the formulae discovery of the decay of sound wave transmission, because the normal hearing of people's ear is at 65-70db, the sound that we set alignment regions needs is 65db, the power of the loudspeaker on the cambered surface audio amplifier so just can calculated according to distance, due to the loudspeaker often doubled, sound can increase 3db, so according to the directional sound having 16 loudspeaker in Fig. 4, be 65db at the sound of alignment regions, can reduce by 12 db around alignment regions is 53db.
As shown in Figure 5, this cambered surface audio amplifier comprises 8*8 and has 64 loudspeaker altogether, the watt level of loudspeaker is gone out according to the formulae discovery of the decay of sound wave transmission, because the normal hearing of people's ear is at 65-70db, the sound that we set alignment regions needs is 65db, the power of the loudspeaker on the cambered surface audio amplifier so just can calculated according to distance, due to the loudspeaker often doubled, sound can increase 3db, so according to the directional sound having 64 loudspeaker in Fig. 5, be 65db at the sound of alignment regions, can reduce by 18 db around alignment regions is 47db.
Composition graphs 3 can draw to the example of Fig. 5, and the quantity of loudspeaker is more, better for directional effect, less at the extra-regional sound of orientation, when the quantity of loudspeaker is increased to certain quantity, even can accomplish outside alignment regions, people's ear can't hear sound, can realize the transaudient of orientation.
Cambered surface directional sound of the present invention, is particularly useful for each venue in museum, owing to having good directional effect, just can make not interfere with each other between the sound of each venue.
Structure of the present invention is simple, and easy to use, the loudspeaker arranged by cambered surface, can reach the effect of sound orientation, and can by different radians, the setting of the loudspeaker of varying number, can reach different poly-audio fruits, have very strong practicality.
