Abstract
The utility model provides a coaxial -type is package assembly for speaker relates to a package assembly, including woofer and loudspeaker, be provided with the screw thread on the woofer, the last screw thread that also is provided with of loudspeaker to use with screw thread on the woofer is supporting, make loudspeaker through the axial rotatory realize with being connected or unpacing apart of woofer, in the woofer, including bass cone, foraminiferous round platform and tweeter horn, the non - enclosed construction of foraminiferous round platform for only constituting by the side, the upper and lower plane of foraminiferous round platform respectively with the upper and lower plane coincidence of tweeter horn, the side of foraminiferous round platform is located between bass cone and the tweeter horn, the side random distribution of foraminiferous round platform the aperture. The accessory that the package assembly of screw thread relates to is few, is favorable to controlling manufacturing cost to packaging technology is simple, nimble, and it is more convenient that the messenger assembles and dismantles, the utility model discloses in the design of the foraminiferous round platform reflected energy of can attenuateing.
Description
Technical field
The utility model relates to a kind of package assembly, is specifically related to a kind of coaxial loudspeaker package assembly.
Background technology
In conventional art, coaxial loudspeaker comprises bass horn and loudspeaker, and bass horn is connected with screw etc. by connecting plate with loudspeaker.The parts related to comprise bass horn, loudspeaker, connecting plate and screw etc., and wherein screw volume is little and more than one, and the accessory that such package assembly relates to is many, and packaging technology is comparatively complicated, and dismounting inconvenience.
In the bass horn of coaxial loudspeaker, include bass cone and tweeter horn, tweeter horn can form reflection to the sound wave of bass cone radiation, especially serious to the acoustic reflection of frequency near 1000Hz, thus affects the Frequency Response of bass horn in coaxial loudspeaker.
Summary of the invention
The purpose of this utility model is to provide a kind of coaxial loudspeaker package assembly, simplifies the assembling fittings of coaxial loudspeaker loudspeaker, makes assembling more convenient and flexible; Reduce and even eliminate bass horn alt horn to the reflections affect of bass cone radiative acoustic wave.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of coaxial loudspeaker package assembly, comprise bass horn and loudspeaker, bass horn is provided with screw thread, loudspeaker is also provided with screw thread, and support the use with the screw thread on bass horn, make loudspeaker realize with the connection of bass horn by axial-rotation or take apart; In bass horn, comprise bass cone, round platform with holes and tweeter horn, round platform with holes is the non-close structure be only made up of side, the lower planes of round platform with holes overlaps with the lower planes of tweeter horn respectively, the side of round platform with holes is between bass cone and tweeter horn, and the side random distribution of round platform with holes aperture.Wherein, the design of screw thread makes the connection of bass horn and loudspeaker and takes apart convenient, and the parts of design are also less, are conducive to production control cost; The design of round platform with holes, changes the reflection path to bass cone radiative acoustic wave, effective attenuation reflected energy.
Further, in a kind of coaxial loudspeaker package assembly of the utility model, the screw thread on bass horn is internal thread, and the screw thread on loudspeaker is external screw thread.Because bass horn build is comparatively large and be positioned on loudspeaker, such Design of Screw Thread is the most reasonable.
Further, in a kind of coaxial loudspeaker package assembly of the utility model, the lateral thickness of round platform with holes is 3mm, and the hole diameter on side is between 2mm ~ 5mm, and pitch-row is about 1mm.In the bass horn of conventional coaxial formula loud speaker, the 1000Hz acoustic reflection of tweeter horn to the radiation of bass cone is serious, in the utility model, the thickness of frustum cone side with holes, the diameter range of aperture determine to play attenuation to the acoustic wave energy of which Frequency point together with pitch-row, derived by the series of theories being core with helmholtz resonance principle and draw, frustum cone side thickness with holes be 3mm, hole diameter between 2mm ~ 5mm, pitch-row is when being 1mm, can the reflected energy of effective attenuation frequency near 1000Hz.
The beneficial effects of the utility model are, the accessory that the package assembly of screw thread relates to is few, is conducive to production control cost, and simple for assembly process, flexible, makes assembly and disassembly convenient, in the bass horn of conventional coaxial formula loud speaker, the 1000Hz acoustic reflection of tweeter horn to the radiation of bass cone is serious, in the utility model, the design of round platform with holes can reflection attenuation wave energy, the thickness of frustum cone side with holes, the diameter range of aperture determines to play attenuation to the acoustic wave energy of which Frequency point together with pitch-row, derived by the series of theories being core with helmholtz resonance principle and draw, frustum cone side thickness with holes is 3mm, hole diameter is between 2mm ~ 5mm, when pitch-row is 1mm, the reflected energy of energy effective attenuation frequency near 1000Hz, thus improve the Frequency Response of coaxial loudspeaker bass horn part.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of coaxial loudspeaker package assembly of the utility model.
Reference numeral: bass horn 1, loudspeaker 2, cone 3, tweeter horn 4, internal thread 5, external screw thread 6, round platform 7 with holes.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Described embodiment is the utility model preferably execution mode; the utility model is not limited to described embodiment, all should be considered as belonging to protection range of the present utility model in the simple transformation done on creative work basis as those of ordinary skill.
As shown in Figure 1, a kind of coaxial loudspeaker package assembly, comprise bass horn 1 and loudspeaker 2, bass horn 1 is provided with internal thread 5, loudspeaker 2 is provided with external screw thread 6, internal thread 5 and external screw thread 6 support the use, and make loudspeaker 2 realize with the connection of bass horn 1 by axial-rotation or take apart.In bass horn 1, comprise bass cone 3, round platform with holes 7 and tweeter horn 4, round platform 7 with holes is the non-close structure be only made up of side, the lower planes of round platform 7 with holes overlaps with the lower planes of tweeter horn 4 respectively, the side of round platform 7 with holes is between bass cone 3 and tweeter horn 4, and the side random distribution of round platform 7 with holes aperture (not shown).The lateral thickness of round platform 7 with holes is 3mm, and aperture (not shown) diameter on side is between 2mm ~ 5mm, and pitch-row is about 1mm.
