Loudspeaker structure based on ring shaft phase-reversing tube application

Abstract

The invention relates to a loudspeaker structure based on ring shaft phase-reversing tube application. The loudspeaker structure comprises a loudspeaker body structure body which is composed of an outer panel and an inner installation panel, wherein a plurality of ring shaft phase-reversing tubes are arranged between the installation panel and a loudspeaker body structure. A voice coil center serves as the virtual axis, and the two or more phase-reversing tubes are mirrored based on the axis or surround the loudspeaker. High voice, medium voice and low voice are restored by approaching to a point acoustic source. A cylindrical or regular polygon cavity structure is adopted, the problem of loudspeaker body resonance caused by a weak center of a panel is solved, and the purpose of eliminating resonance can be achieved relatively with quite thin materials. Due to the fact that the combination of the phase-reversing tubes and the loudspeaker body is organically utilized, two cylindrical inner cavities which are communicated in a front-and-rear mode and integrated but are not equal in diameter are formed, the bordering length is just set in the middle segments, where standing waves are extremely prone to generation, of the inner cavities, and the formation of the standing waves is effectively damaged. The installation panel of the loudspeaker is in the shape of a chamfered cone frustum, the area of the panel is larger than the loudspeaker, and right ahead reflecting of reflected waves and superimposed interference of diffraction sound waves are evenly and effectively relieved.

Description

technical field [0001] The invention relates to the sound box design technology, in particular to a sound box structure based on the application of a ring shaft phase guide tube. Background technique [0002] At present, in the traditional speaker structure, the cabinet mostly adopts an upright cuboid structure. The speaker unit and the inverter tube are placed on one side of the cabinet, and there is a certain distance. It is bound to be damaged, and the box body is a cuboid structure composed of long strips of plate-shaped materials. The center point of each plate is also the weakest. The outside is affected by the resonance of the cabinet to produce sound dyeing, and the inside is relatively regular to produce standing waves. These two points greatly reduce the sound to be reproduced. The area of ​​the box panel is too large, and the reflected waves generated by the edges and corners of the square structure produce superimposed interference on the beneficial sound waves....
