Abstract
The utility model relates to an air defense warning loudspeaker, comprising a speech coil (1), a speech membrane (2), a magnetic circuit, and a loud-speaking unit composed of a big, middle, and small horn (3, 4, 5). The utility model is characterized in that the air defense warning loudspeaker is provided with a plurality of groups of loud-speaking units. The big horns (3) of every group of loud-speaking units are uniformly distributed radially on the same horizontal plane, and are in the integration structure. The air defense warning loudspeaker is also provided with a vertical supporting bar (6), and the loud-speaking unit is fixed to the supporting bar (6) removably. The defects of inconvenient installation caused by adopting several common horn loudspeakers to be directly assembled for play back, crude appearance, moving inconvenience, as well as the blind angles of playback, are overcome.
Description
Technical field: the utility model relates to a kind of electroacoustic loud speaker, particularly horn formula air defence warning loud speaker.
Background technology: because that the horn formula is raised the device volume is big, highly sensitive, transmission sound is far away, therefore is used to do air defence warning, propaganda broadcast loud speaker.But horn loudspeaker directive property is strong, can not be simultaneously to around send identical volume, as adopting the matrix-style that will several common horn loudspeakers be arranged in to four direction, inconvenience is installed then, the mobile and playback dead angle in addition of the coarse also inconvenience of outward appearance.
Summary of the invention: the purpose of this utility model is to provide a kind of horn loudspeaker that does not have playback dead angle, compact conformation, is suitable for doing the air defence warning loud speaker for the defective that overcomes prior art.
The technical solution that the utility model adopts is as follows: the air defence warning loud speaker, comprise the speaker unit that voice coil loudspeaker voice coil, sound film, magnetic circuit and large, medium and small horn are formed, it is characterized in that: described air defence warning loud speaker is provided with many group speaker unit, and each big horn of organizing speaker unit becomes radial even distribution and being integral structure on same horizontal plane; Described air defence warning loud speaker also is provided with a vertical support bar, and described speaker unit removably is fixed on the support bar.
Of the present utility modelly further be set to: described integrated big horn is connected on the parallel circle ring-type by central tube two ends, lower bottom cover constitutes, on, being provided with some vertical partition plates between the lower bottom cover is separated into several horn-like spaces that equate and constitutes big horn, during each big horn center is provided with separately, little horn, each organizes voice coil loudspeaker voice coil, the sound film, magnetic circuit is arranged on the central tube on the inwall at corresponding big horn center forms the integrated speaker unit of many groups, on described, also be covered with slightly arch of central authorities on the lower bottom cover, on the dish shape, following rain cover, on described, following rain cover external diameter and last, lower bottom cover equates, be provided with suitable shoulder rank between the outer rim of rain cover and bottom, evenly be provided with the installing hole that several vertically connect on the described central tube end face, post upper is provided with the installation supporting plate, install supporting plate and down rain cover be provided with corresponding installing hole, bolt penetrates installing hole and is connected in and will organizes integrated speaker unit more on the rain cover from the below, on, following rain cover is fixed on the support bar.
Of the present utility modelly further be set to: described central tube cross section for and the corresponding regular polygon of speaker unit group number, described dividing plate horizontal direction is curved, per two dividing plates are one group, concave surface is oppositely arranged.
Of the present utility modelly further be set to: described central tube and upper and lower bottom, dividing plate are one, and upper and lower bottom corresponding two part between the dividing plate concave surface on the same group hollows out.
Of the present utility modelly further be set to: many groups of integrated speaker unit that are provided with two-layer or two-layer above same structure between the upper and lower rain cover of described air defence warning loud speaker.
Forming air defence warning with existing common horn loudspeaker raises and compares, the beneficial effect that the utlity model has is: owing to adopted a plurality of speaker unit of radial arrangement in the horizontal direction, being integral structure between the big horn of each speaker unit, eliminated the dead angle of sound transmission, and compact conformation, maximally utilise the space, be convenient to install and shift, in addition also can be according to the requirement of the power that amplifies is improved power with the speaker unit mode of a plurality of same structures that superpose.
The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
Description of drawings:
Accompanying drawing 1 is the utility model example structure cutaway view;
Accompanying drawing 2 is the integrated speaker unit front views of the many groups of embodiment;
Specific embodiment: as shown in the figure, air defence warning loud speaker of the present utility model comprises voice coil loudspeaker voice coil 1, sound film 2, magnetic circuit and big, in, small size tube 3,4,5 speaker unit and the support bars of forming 6, integrated big horn 3 is connected on the parallel circle ring-type by a central tube 15 two ends, lower bottom cover 7,8 constitute, on, lower bottom cover 7, being provided with some vertical partition plates 13 between 8 is separated into several horn-like spaces that equate and constitutes big horn 3, dividing plate 13 horizontal directions are curved, per two dividing plates 13 are one group, concave surface is relative, the outer ledge setting of joining, help eliminating the playback dead angle, during each big horn 3 center is provided with separately, little horn, each organizes voice coil loudspeaker voice coil 1, sound film 2, magnetic circuit is arranged on the central tube 15 on the inwall at corresponding big horn 3 centers forms the integrated speaker unit of many groups, on described, lower bottom cover 7, also be covered with circle on 8, central authorities are arch slightly, on the dish shape, following rain cover 9,10, on described, following rain cover 9,10 external diameters and last, lower bottom cover 7,8 equate, be provided with suitable shoulder rank between the outer rim of rain cover and bottom and be beneficial to the location, evenly be provided with the installing hole 14 that several vertically connect on described central tube 15 end faces, support bar 6 upper ends are provided with installs supporting plate 11, installation supporting plate 11 reaches down, and rain cover 10 is provided with corresponding installing hole 14, bolt 12 penetrates installing hole 14 and is connected on the rain cover 9 from the below, with integrated big horn 3, on, following rain cover 9,10 are fixed on the support bar 6.Loudspeaker unit can be selected between the 4-8 group as required, and 6 groups of speaker unit are set in the present embodiment.
For just with the technology that adopts casting, central tube 15 can be designed to one with upper and lower bottom 7,8 and dividing plate 13 for one, upper and lower bottom 7,8 corresponding two part between dividing plate 13 concave surfaces on the same group can hollow out with weight reduction, economical with materials in addition also can be according to the requirement of the power that amplifies is improved power with the speaker unit mode of a plurality of same structures of stack.
