Detailed description of the invention
Embodiment 1
As Figure 1-3, the utility model built-in paraphase device sound column, form primarily of the loudspeaker 2 on the left of cylindrical housings 1, housing 1 and the base 3 under housing 1, loudspeaker comprise magnet and paper disc, the opposite side that described circular cylindrical shell intracoelomic cavity loudspeaker magnetic iron is relative is provided with air-flow by-pass means 4, this by-pass means 4 and loudspeaker concentric, it comprises inside and outside confronting coaxial streams cover (41,42), inside and outside stream the gas channel 5 that cover (41,42) junction forms two symmetrical S waveform groove; Described loudspeaker 2 are oppositely arranged on both sides in cylindrical housings 1 with air-flow by-pass means 4, arrange gap therebetween.Streaming cover 41 in described primarily of two hemispherical covers connects formation, and centre is provided with conical tank, conical tank end with stream cover 42 outward and be connected; The described outer cover 42 that streams is formed primarily of the hemispherical cover that two are left spacing, and be the horn structure of depression in the middle of hemispherical cover, bottom is sender 6, and outside is integrated with cylindrical housings 1 to be connected.Stream in described bottom cover 41 and be also provided with reinforcement, this reinforcement is that the equal circumference of cruciform symmetry is arranged, can strengthen the intensity of streaming cover.Described cylindrical housings is also provided with framework 7, and framework 7 one end is connected and fixed the base of loudspeaker 2; The other end is provided with the audio frequency diffuser 8 of taper.During work, the air-flow of framework inner housing, when two gas channels 5 of waveform groove, is turned back through overcompression and is passed through, then releases from sound mouth and external audio amplifier, and low frequency can be made so deep and forceful, and acoustical quality is good.
