Abstract
The invention discloses an acoustically transparent waveguide horn which comprises a bass horn and a tweeter horn, wherein, the rear end of the bass horn is provided with a bass driver, and the rear end of the tweeter horn is provided with a tweeter driver; the tweeter horn is arranged inside a cavity of the bass horn, and through holes are arranged on the wall of the tweeter horn. As the opening wall of the tweeter horn is provided with the through holes, bass sound wave can be radiated out through the through holes, the effective radiation area of the bass horn can be enlarged, and the chamber effect is avoided from appearing in the cavity of the bass horn; therefore, the invention not only guarantees pointing control capability and the lower limit of working frequency, but also leads the bass horn to have satisfying radiating area without increasing the volume of the bass horn, thus enlarging the application scope of the horn.
Description
Technical field
The present invention relates to a kind of electroacoustic apparatus, particularly a kind of acoustically transparent waveguide horn.
Background technology
Horn speaker is made up of horn and driver, owing to it has in the controlled sound reinforcement system that is widely used in various occasions of very high transfer voice efficient and stronger direction, employing is arranged also on conventional audio amplifier.Wherein, the tweeter horn and the high-pitched driver that are used for the high pitch public address are formed horn loudspeaker, and the bass horn and the bass drivers that are used for the bass public address are formed the bass horn speaker.
The composite type horn is the horn that is composited by tweeter horn and bass horn, and this combined type horn in order to reduce volume, is contained in bass horn front portion with tweeter horn and high-pitched driver when design.But, this structure has occupied about 1/2nd bass horn swept area owing to the soprano saxhorn nozzle opens area, if make tweeter horn directive property wideer, more constant or the operating frequency lower limit is lower, the area of soprano saxhorn nozzle needs further to increase, this can make the swept area of bass horn further reduce, and the chamber effect appears, and make the public address degradation of bass, influence the definition of public address; If reduce the opening subtended angle or the area of tweeter horn, can reduce the influence of bass horn, but its point to control will variation; If opening subtended angle or area that should tweeter horn be enough big, the bass horn is unaffected again, the bass horn further can only be strengthened again, certainly will increase the overall volume of composite type horn like this, has limited the scope of application of composite type horn.
Summary of the invention
In order to solve the above problems, the object of the present invention is to provide a kind of under the situation of the overall volume that does not increase the composite type horn, can guarantee that tweeter horn points to control ability and operating frequency lower limit, can make the bass horn have the acoustically transparent waveguide horn of good swept area again.
The present invention solves the technical scheme that its problem adopts:
A kind of acoustically transparent waveguide horn comprises bass horn and tweeter horn, and described bass saxhorn tube rear end is provided with bass drivers, and described tweeter horn rear end is provided with high-pitched driver, and tweeter horn is contained in the bass horn cavity, and the barrel of described tweeter horn is provided with through hole.
As further improvement, described through hole is communicated with bass horn cavity and tweeter horn cavity.
As further improvement, described through hole is towards the tweeter horn edge punishment cloth comparatively dense of dehiscing.
As further improvement, dehisce the physical dimension of the near through hole in edge greater than the edge through hole far away of dehiscing from tweeter horn from tweeter horn.
The invention has the beneficial effects as follows: owing to have through hole on the tweeter horn perforated wall, can be so that bass sound radiate by these holes, increase the effective radiating area of bass horn, avoid the chamber effect occurring in the bass horn chamber, can guarantee that tweeter horn points to control ability and operating frequency lower limit, can make the bass horn have good swept area again and do not need to increase the volume of bass horn, increase the scope of application of composite type horn.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and example:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a generalized section of the present invention;
Fig. 3 is the embodiment of the invention two structural representations;
Fig. 4 is the embodiment of the invention two generalized sections.
Embodiment
Referring to figs. 1 to 4, a kind of acoustically transparent waveguide horn, comprise bass horn 1 and tweeter horn 2, described bass saxhorn tube rear end is provided with bass drivers 3, and described tweeter horn rear end is provided with high-pitched driver 4, and tweeter horn 2 is contained in the bass horn cavity 11, the barrel of described tweeter horn 2 is provided with through hole 20, during use, transfer out by these through holes in a low voice, increase the effective radiating area of bass horn.
Described through hole 20 is communicated with bass horn cavity 11 and tweeter horn cavity 21.
Described through hole 20 is towards the tweeter horn 3 edge punishment cloth comparatively dense of dehiscing.
Dehisce near through hole 20 physical dimensions in edge greater than the edge through hole far away of dehiscing from tweeter horn 2 from tweeter horn 2.
Certainly, described high pitch, the opening shape of bass horn can be circular or other shapes; The tweeter horn that is contained in the bass horn can be for a plurality of; Bass horn cavity also can be divided into a plurality of chambers by tweeter horn.
The invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
