Description
Technical field
The present invention 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 big, 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 characteristic of directive property, effectively the transfer voice angle generally is no more than 90 degree in the horizontal direction, even adopt awl benzvalene form loud speaker, its transmission face also is no more than 120 degree.In order to obtain wider transfer voice, at present modes that adopt many loud speakers and the combination of a plurality of audio amplifier more, or in many places suspension horn loudspeaker and many places settle method such as audio amplifier to go to realize.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, connected wire rod and area occupied etc.Therefore, need a kind of New-type loudspeaker that can address the above problem now.
Summary of the invention
The present invention is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, can carry out the loud speaker of transfer voice simultaneously in level 360 degree omniranges and with the perpendicular direction of horizontal plane.
Technical solution of the present invention 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 is provided with air chamber conduit 4 with vibrating diaphragm 3 tops, is fixed with reflecting drum 5 in 4 outside sockets of air chamber conduit; 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, in the transaudient housing 6 of omnidirectional's level, are evenly distributed with at least four dividing plates 7, and per two adjacent dividing plates 7 are formed 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 through 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 present invention compares 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 to traditional loud speaker in the scope of 120 degree in the plane carries out the defective of transfer voice, 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; Its collection cylinder, radially, multiple horn loudspeaker advantages such as many lattice, the biradial loud speaker that is one, its loudness and transmission face are quite or above 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 the input of auxiliary facilities such as power amplifier, connecting line simultaneously accordingly, 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 with the perpendicular direction of horizontal direction on carry out transfer voice, promptly 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, we can say that it has possessed multiple advantage, is particularly suitable for applying in the art.

Embodiment
Below with accompanying drawings embodiment of the present invention.
Embodiment one: like Fig. 1, shown in Figure 2.A kind of omnidirectional sound transmission loud speaker comprises a RP 1 as the basis, in RP 1, is 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; Then socket is fixed with reflecting drum 5 outside air chamber conduit 4, and 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 through this circular center of circle; In the inside of 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, like Fig. 3, shown in Figure 4.On loud speaker, also be provided with vertical transaudient housing 9; This vertical transaudient housing 9 communicates through the inner chamber of opening 10 with reflecting drum 5; And the axis of vertical transaudient housing 9 is vertical each other 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 following: 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; The air of vibration continues vibration wave to be sent among the reflecting drum 5 after through air chamber conduit 4, and is sent in the formed loudspeaker monomer 8 of upper and lower casing by transaudient housing 6 dishes of dividing plate 7 and omnidirectional's level, to realize the purpose of omnidirectional's 360 degree transfer voice in the horizontal direction;
