Abstract
The utility model provides a two-unit single magnetic body coaxial loudspeaker. A magnetic conducting core column is arranged in the center of the bottom part in a magnetic conducting bowl, a two-unit sharing magnetic body with the tube coil shape around the magnetic conducting core column is arranged on the bottom part in the magnetic conducting bowl, a two-unit sharing magnetic conducting pole plate coil is arranged on the magnetic body, a cone frame provided with voice cone and a corrugated support piece is arranged on the magnetic conducting bowl, the upper end is connected with the voice cone, the lower part connected with a low voice coil or a medium voice coil is positioned in a magnetic air gap between the inner wall of the magnetic conducting bowl and the outer circumference surface of the magnetic conducting pole plate coil, the medium voice or the high voice or the super high voice membrane voice coil is arranged on the magnetic conducting pole plate coil through a supporting frame, and the voice coil is positioned in a magnetic air gap between the inner circumference surface of the magnetic conducting pole plate coil and the magnetic conducting core column. The utility model has the advantages that the structure is compact, the processing process is simple and reliable, and the cost is low, and then a more ideal loudspeaker is provided for the top grade sound, in particular to the top grade sound device with the small volume.
Description
Technical field
The utility model relates to a kind of loud speaker, particularly the multiple unit coaxial loudspeaker.
Background technology
The multiple unit coaxial loudspeaker, have compact conformation, volume is small and exquisite, coaxial concurrent sound source broadcast, the range broadness, tone color is clear, the advantage that high-fidelity etc. are outstanding, but because its structural design difficulty is bigger, thus in the market Cheng Shu multiple unit coaxial loudspeaker product variety seldom, its patent disclosure technology is several also few, still need and constantly research and develop, to satisfy the needs of different occasions, different levels stereo set.
Summary of the invention
The purpose of this utility model is the new varieties that a kind of novel and reasonable structure is provided for coaxial loudspeaker " family "---two unit list magnet coaxial loudspeakers.
The technical solution of the utility model is: it has the magnet that constitutes the magnetic circuit of loudspeaker, the magnetic conduction pole plate, magnetic conductive core column, magnetic conductor bowl, with the sound basin voice coil loudspeaker voice coil and the diaphragm voice coil loudspeaker voice coil that constitute vibrational system, it is characterized in that magnetic conductor bowl inner bottom part center is equipped with vertical magnetic conductive core column, magnet is two units shared magnets, and be cylinder shape and be installed on the magnetic conductor bowl inner bottom surface round magnetic conductive core column, the pole-guiding borad ring of two units shareds is installed above the magnet, being provided with the basin frame that sound basin and ripple prop up sheet is installed on the magnetic conductor bowl, bass or middle pitch voice coil loudspeaker voice coil that the upper end is connected with the sound basin, in the magnetic air gap that its underpart is positioned to form between magnetic conductor bowl inwall and the pole-guiding borad ring outer peripheral face, middle pitch or high pitch or superelevation sound diaphragm voice coil loudspeaker voice coil are installed on the pole-guiding borad ring by its support, and make in the magnetic air gap that its voice coil loudspeaker voice coil is positioned to form between pole-guiding borad ring inner peripheral surface and the magnetic conductive core column.
The utility model compact conformation is reasonable, and processing technology is simple and reliable, and cost is low, is high end audio, and particularly small size high end audio device provides a kind of comparatively ideal loud speaker.
Description of drawings
Accompanying drawing is a general structure schematic diagram of the present utility model.
Embodiment
The magnetic conductor bowl 1 inner bottom part center of present embodiment is equipped with the magnetic conductive core column 3 contour with magnetic conductor bowl 1, the magnet 2 of two units shareds is cylinder shape and is installed on magnetic conductor bowl 1 inner bottom surface round magnetic conductive core column 3, be connected with the pole-guiding borad ring 4 of two units shareds on the magnet 2, on the pole-guiding borad ring 4 plane basically with magnetic conductor bowl 1 on the plane mutually concordant; The basin frame 7 that sound basin 8 and ripple prop up sheet 9 is installed is connected and installed on the magnetic conductor bowl 1, the bass voice coil loudspeaker voice coil 10 that the upper end is connected with sound basin 8 is in the magnetic air gap that its underpart is positioned to form between magnetic conductor bowl 1 inwall and pole-guiding borad ring 4 outer peripheral faces; High sound diaphragm voice coil loudspeaker voice coil 11 is installed on the pole-guiding borad ring 4 by its support, and its voice coil loudspeaker voice coil is positioned in the magnetic air gap of formation between pole-guiding borad ring 4 inner peripheral surfaces and the magnetic conductive core column 3; In order to strengthen the leading note effect, the leading note bullet screen covering 5 of cover cap diaphragm voice coil loudspeaker voice coil 11 is installed on pole-guiding borad ring 4, acoustical cotton 6 is installed in diaphragm voice coil loudspeaker voice coil 11, above the magnetic conductive core column 3.
