Abstract
The invention provides a column type loudspeaker. The column type loudspeaker comprises a hollow column, wherein a loudspeaker base body towards a tube is fixed on one end of the hollow column, and a cone of the loudspeaker base body seals a port of the hollow column, a piston column is stuffed into the other end of the hollow column, and sound holes are arranged on peripheral walls of the hollow column. The column type loudspeaker can optionally adjust tenuto effects of music being broadcasted, and does not cause any distortion of the music.
Description
Technical field
The present invention relates to stereo set field, especially, relate to a kind of loud speaker.
Background technology
For current loud speaker, if not by means of functional module, the music that the source of sound that can only reduce exports without polishingly; And for the music that tone color is enriched not, after being restored by ventional loudspeakers, seem very dull, appreciate effect poor; For this reason, general method adopts functional module to produce tenuto effect, but this kind of functional module is when processing audio, and audio frequency usually can be caused to produce distortion to a certain degree, therefore effect imperfect.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of column loudspeaker, this column loudspeaker arbitrarily can regulate broadcast tenuto effect, and does not cause any distortion.
The technical solution adopted for the present invention to solve the technical problems is: this column loudspeaker comprises one section of open tubular column; One end of described open tubular column is fixed with loud speaker matrix in pipe; The sound basin of described loud speaker matrix is by the port closed of this open tubular column; The other end of described open tubular column fills in a piston boit; The uniform acoustic aperture of perisporium of described open tubular column.
As preferably, described open tubular column is vertically fixed on a pedestal, and described piston boit inserts in described open tubular column from top to bottom, and the upper end of piston boit has pressing plate.
As preferably, the lower surface of described piston boit is made up of metallic plate, makes it to have good acoustic wave reflectivity capability.
Beneficial effect of the present invention is: this column loudspeaker in playing process, the sound basin of described loud speaker matrix to described piston boit bottom surface between distance be the one-way only propagation distance of sound; The music produced from described loud speaker matrix is pushed forward process, a part is directly outwards propagated from the acoustic aperture of open tubular column perisporium, after another part arrives the bottom surface of described piston boit, transmit outside acoustic aperture in return, thus form the transmission time difference being proportional to described one-way only propagation distance, thus form tenuto effect, owing to not having, any electricity process is done to audio frequency, so do not produce any distortion; And by the described piston boit of pressing, change the degree of depth that it stretches into open tubular column, i.e. adjustable tenuto degree, adjustment process and convenience thereof.
Accompanying drawing explanation
Fig. 1 is an embodiment schematic diagram of this column loudspeaker.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in fig. 1, this column loudspeaker comprises one section of open tubular column 1; This open tubular column 1 is vertically fixed on the base 2, is provided with audio interface in described pedestal 2.
The lower end of described open tubular column 1 is fixed with loud speaker matrix 3 in pipe; The sound basin of described loud speaker matrix 3 is by the port closed of this open tubular column 1; A piston boit 4 is filled in the upper end of described open tubular column 1; The uniform acoustic aperture 100 of perisporium of described open tubular column 1.
Described piston boit 4 inserts in described open tubular column 1 from top to bottom, forms the operatic tunes 50 between the bottom surface of piston boit 4 and the sound basin of loud speaker matrix 3; The upper end of piston boit 4 has pressing plate 41, be beneficial to piston boit 4 press down and on pull out.The lower surface of described piston boit 4 is made up of metallic plate, makes it to have good acoustic wave reflectivity capability.
Above-mentioned column loudspeaker in playing process, the sound basin of described loud speaker matrix 3 to described piston boit 4 bottom surface between distance be the one-way only propagation distance of sound, that is the length of the described operatic tunes 50; The music produced from described loud speaker matrix 3 is pushed forward process, a part is directly outwards propagated from the acoustic aperture 100 of open tubular column 1 perisporium, after another part arrives the bottom surface of described piston boit 4, transmit outside acoustic aperture 100 in return, thus form the transmission time difference being proportional to described one-way only propagation distance, thus form tenuto effect, owing to not having, any electricity process is done to audio frequency, so do not produce any distortion; And by the described piston boit 4 of pressing, change the degree of depth that it stretches into open tubular column 1, i.e. adjustable tenuto degree, adjustment process and convenience thereof.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, all should be included within protection scope of the present invention.
