Abstract
The utility model discloses an omnidirectional sound transmission loudspeaker, which comprises a standard sounding head (1). Voice coils (2) and a diaphragm (3) are arranged inside the standard sounding head (1). The omnidirectional sound transmission loudspeaker is characterized in that an air chamber guide pipe (4) is arranged above the voice coils (2) and the diaphragm (3); a reflection cylinder (5) is fixed on the outer side of the air chamber guide pipe (4) in a sleeving way; the inner chamber of the reflection cylinder (5) is communicated with an omnidirectional horizontal sound-transmission housing (6) with a round cross section; the upper housing and the lower housing of the omnidirectional horizontal sound-transmission housing (6) are plate-shaped; at least four separator plates (7) are uniformly distributed inside the omnidirectional horizontal sound-transmission housing (6); and every two adjacent separator plates (7) and the omnidirectional horizontal sound-transmission housing (6) form a horn-shaped loudspeaker single body (8). The omnidirectional sound transmission loudspeaker which has the characteristics of simple structure, clever design and reasonable layout can simultaneously perform sound transmission in all 360-degree horizontal directions and also in directions perpendicular to the horizontal plane.
Description
Technical field
The utility model relates to a kind of loud speaker, particularly a kind of omnidirectional sound transmission loud speaker.
Background technology
Horn loudspeaker is because its power is large, efficient is high, propagation distance is far away etc. advantage, is widely used in meeting-place, field, wide open country broadcasting and occasions such as warning and long-distance communications.But have certain defective on the existing horn loudspeaker structure, cause it to have the sharp-pointed feature of directive property, effectively the transfer voice angle generally is no more than 90 degree in the horizontal direction, even adopt cone benzvalene form loud speaker, its transmission face also is no more than 120 degree.In order to obtain wider transfer voice, adopt at present the modes of many loud speakers and a plurality of loudspeaker box combinations more, or go to realize in methods such as many places suspension horn loudspeaker and many places arrangement audio amplifiers.These methods not only increase input, the increase working strength of loud speaker or audio amplifier, but also doubly measure the input that has increased power amplifier, connection wire and area occupied etc.Therefore, need now a kind of New-type loudspeaker that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, can carry out simultaneously the loud speaker of transfer voice in the horizontal 360-degree omnirange and with the perpendicular direction of horizontal plane.
Technical solution of the present utility model is: a kind of omnidirectional sound transmission loud speaker, comprise RP 1, in RP 1, be provided with voice coil loudspeaker voice coil 2 and vibrating diaphragm 3, it is characterized in that: described voice coil loudspeaker voice coil 2 and vibrating diaphragm 3 tops are provided with air chamber conduit 4, be fixed by socket reflecting drum 5 in air chamber conduit 4 outsides, the inner chamber of reflecting drum 5 is communicated with for the circular transaudient housing 6 of omnidirectional's level with cross section, and the upper shell of the transaudient housing 6 of omnidirectional's level and lower house are dish, be evenly distributed with at least four dividing plates 7 in the transaudient housing 6 of omnidirectional's level, per two adjacent dividing plates 7 form horn type loudspeaker monomer 8 with the transaudient housing 6 of omnidirectional's level.
The inner chamber of described reflecting drum 5 also communicates with vertical transaudient housing 9 by opening 10, and the plane at the transaudient housing of the axis of vertical transaudient housing 9 and omnidirectional's level 6 places is perpendicular.
The utility model is compared with prior art, has following advantage:
Omnidirectional's sound transmission loud speaker of this kind of version, it is simple in structure, designs ingenious, rationally distributed, it can only be not more than the defective of carrying out transfer voice in 120 scopes of spending in the plane for traditional loud speaker, designs the structure of single sound producing head, omnirange transfer voice.The appearance of this loud speaker can realize the transfer voice on the 360 degree omniranges; It integrate cylinder, radially, the loud speaker of the multiple horn loudspeaker advantages such as many lattice, biradial, its loudness and transmission face are quite or surpass horn speaker traditional more than 4; Hardware cost when greatly having reduced multi-direction sound transmission, reduced the labour intensity of installation, dismounting and a plurality of loud speakers of maintenance, also reduced accordingly simultaneously the input of the auxiliary facilities such as power amplifier, connecting line, the hyperbolic configuration of simultaneously this two dish-shaped transaudient housings and dividing plate has also been widened the transmission index of vertical direction.It can either carry out transfer voice in 360 scopes in the horizontal direction, simultaneously can also carry out transfer voice with the perpendicular direction of horizontal direction, and namely it can realize carrying out simultaneously on horizontal direction and the hemispherical space function of transfer voice.And the manufacture craft of this horn loudspeaker is simple, and is cheap for manufacturing cost, can say that it has possessed multiple advantage, is particularly suitable for applying in the art.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
Embodiment one: as shown in Figure 1 and Figure 2.A kind of omnidirectional sound transmission loud speaker, comprise one as the RP 1 on basis, in RP 1, be provided with voice coil loudspeaker voice coil 2 and vibrating diaphragm 3, above voice coil loudspeaker voice coil 2 and vibrating diaphragm 3, be provided with air chamber conduit 4, outside air chamber conduit 4, then be fixed by socket reflecting drum 5, the inner chamber of reflecting drum 5 is connected with the omnidirectional transaudient housing 6 of level, and the cross section of the above-mentioned transaudient housing 6 of omnidirectional's level is circular, the axis of reflecting drum 5 is by this circular center of circle, inside at the transaudient housing 6 of omnidirectional's level, be uniformly distributed with at least four dividing plates 7, form a trumpet-shaped loudspeaker monomer 8 between per two adjacent dividing plates 7;
Embodiment two, as shown in Figure 3, Figure 4.On loud speaker, also be provided with vertical transaudient housing 9, this vertical transaudient housing 9 communicates by the inner chamber of opening 10 with reflecting drum 5, and the axis of vertical transaudient housing 9 is mutually vertical with the plane at the omnidirectional transaudient housing of level 6 places, its opening also is horn-like, with transfer voice state that can cover hemispherical direction of the transaudient housing 6 common formation of omnidirectional's level.
The course of work of the omnirange transfer voice loud speaker of this kind of version is as follows: in embodiment one, RP 1 is after energising, voice coil loudspeaker voice coil 2 in it drives vibrating diaphragm 3 vibrations, vibrating diaphragm 3 sends sound to air chamber conduit 4, behind the air process air chamber conduit 4 of vibration vibration wave is continued to be sent among the reflecting drum 5, and be sent in the formed loudspeaker monomer 8 of upper and lower casing by dividing plate 7 and transaudient housing 6 dishes of omnidirectional's level, to realize the in the horizontal direction purpose of omnidirectional's 360 degree transfer voice;
