Specific embodiment
A kind of array speaker with compression design of the present invention is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of array speaker with compression design, including sound box body and is arranged in raising in sound box body
Sound device assembly, the loudspeaker assembly include several loudspeakers 1, mounting bracket 2 and several compressors, in mounting bracket 2
Several mounting grooves are provided with, loudspeaker 1 is fixedly mounted in mounting groove correspondingly, is both provided on each loudspeaker 1
One compressor, compressor are placed in 1 upper end of loudspeaker and are fixed in mounting bracket 2.When sound box body works, sound passes through loudspeaking
Device 1 dissipates, and the compressor being mounted on loudspeaker 1 can compress mesohigh, so that the orientation angle of sound expands.
For further, compressor includes the first compression piece 31 and the second compression piece 32, and the first compression piece 31 is placed in loudspeaking
1 upper end of device, the second compression piece 32 are placed in 31 upper end of the first compression piece.
For further, as shown in Fig. 2, the first compression piece 31 includes the first framework 311 and is located in the first framework 311
Air-flow column 313.Be provided with the first compression plate 312 in the two sides of the first framework 311, the first compression plate 312 and loudspeaker 1 it
Between there are certain gap, form airflow channel 33.
For further, since concave structure is presented in the upper surface of loudspeaker 1, so, corresponding first compression plate 312 is in
Domes guarantee that the upper surface of the first compression plate 312 and loudspeaker 1 matches with this, guarantee the unimpeded of airflow channel 33.
For further, as shown in figure 3, the second compression piece 32 includes second framework 321 and is located in second framework 321
Two piece of second compression plate 322, the side of two the second compression plates 322 is connected to two the first compression plates respectively correspondingly
312 inside forms an aditus laryngis 34, since two the second compression plates 322 are oblique, so the diameter of aditus laryngis 34 away from
The direction of loudspeaker 1 is smaller and smaller.This design method compresses sound air-flow, thus the air-flow after aditus laryngis 34 to
External diffusion, so as to improve the orientation angle of sound, so that the sound angle finally issued from entire loudspeaker 1 is wider, failure is more
It is few.
For further, as shown in figure 4, an air-flow column 313 is provided at the center of the first compression piece 31, the air-flow column
313 is hollow, is inserted into aditus laryngis 34, fraction is flowed out from the air-flow column 313, to avoid air-flow after compressor excessively compresses
The prominent height of sonic profile is caused to be dashed forward low.
For further, 31 upper end of the first compression piece is provided with several mounting holes 314, correspondingly, the second compression piece 32
Lower end is provided with several mounting posts 323, and mounting post 323 in insertion mounting hole 314, realizes the second compression correspondingly with this
The fixation of part 32.
For further, high pitch compressor compresses distance is 1~1.5mm, and Hi-Mid compression distance is 4~6mm, compression ratio
About 55%~65%, opening area is about 35%~45%.
Above-mentioned design greatly improves its orientation angle by carrying out compression design to loudspeaker 1, this design
Like being that flowing water is very anxious when many flowing water are pooled to narrow river, before it is following spacious incomparable, water will moment case surrounding
The same reason of diffusion, sound be also in this way, before no compression sound can with vibrating diaphragm direction at certain orientation diffusion,
Can be compared in narrow channel that the sound in other places is all summarized after increasing compression, behind this channel due to once
Son is just rapidly spread around without obstruction sound.Thus greatly increase angle of radiation.
Fig. 5 gives the test curve of the speaker without compression design, and Fig. 6-10 gives the speaker with compression design and exists
Speaker test curve under the conditions of various.By the contrast test of system, show that data are without compression design test in the past
The left and right drift angle of sound radiation is 45 ° (90 ° of total angles), and left and right and the estimated decaying of intermediate comparison are more than 7dB at this time.And pass through
The left and right drift angle for obtaining data as sound radiation is tested after compression design in 90 ° (180 ° of total angles), number or so and centre
The estimated decaying of comparison compares comparison of pervious left and right drift angle when 45 ° (90 ° of total angle) or so with centre more than 5dB
It is expected that decaying is more than 3dB.So making its orientation angle obtain greatly improving and can allow by the compression design to loudspeaker 1
The audience of front and two sides can obtain best audio simultaneously.
For a person skilled in the art, after reading above description, various changes and modifications undoubtedly be will be evident.
Therefore, appended claims should regard the whole variations and modifications for covering true intention and range of the invention as.It is weighing
The range and content of any and all equivalences, are all considered as still belonging to the intent and scope of the invention within the scope of sharp claim.
