Abstract
The invention discloses a horizontal 360-degree omnidirectional radiation loudspeaker which comprises a standard sounding head (1). A loudspeaker voice coil (2) and a vibrating diaphragm (3) are arranged in the standard sounding head (1); the loudspeaker is characterized in that an air chamber guide tube (4) is arranged above the loudspeaker voice coil (2) and the vibrating diaphragm (3); a reflecting cylinder (5) is sleeved and fixed on the outer side of the air chamber guide tube (4); the inner cavity of the reflecting cylinder (5) is communicated with an omnidirectional sound transmission casing (6) with a circular cross section; upper and lower casings of the omnidirectional sound transmission casing (6) are in dish shapes; at least four baffles (7) are uniformly distributed in the omnidirectional sound transmission casing (6); and each two adjacent baffles (7) and the omnidirectional sound transmission casing (6) form a cylindrical loudspeaker monomer (2). The loudspeaker has a simple structure and skillful design, is reasonable in layout, and can perform 360-degree omnidirectional sound transmission.
Description
Technical field
The present invention relates to a kind of loud speaker, particularly a kind of level 360 degree omnidirectional radiation loud speakers.
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 on 360 degree omniranges, carry out the loud speaker of transfer voice.
Technical solution of the present invention is: a kind of level 360 degree omnidirectional radiation loud speakers; 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 with cross section; And the upper shell of the transaudient housing 6 of omnidirectional and lower house are dish, in the transaudient housing 6 of omnidirectional, are evenly distributed with at least four dividing plates 7, per two adjacent dividing plates 7 and the transaudient housing 6 composition horn type loudspeaker monomers 8 of omnidirectional.
The present invention compares with prior art, has following advantage:
The level 360 degree omnidirectional radiation loud speakers 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.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.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the vertical view cutaway drawing of the embodiment of the invention.
Embodiment
Below with accompanying drawings embodiment of the present invention.Like Fig. 1, shown in Figure 2: a kind of level 360 degree omnidirectional radiation loud speakers, comprise one as the RP on basis 1, 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; Then socket is fixed with reflecting drum 5 outside air chamber conduit 4, and the inner chamber of reflecting drum 5 is connected with omnidirectional transaudient housing 6, and the cross section of the transaudient housing 6 of above-mentioned omnidirectional 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, be uniformly distributed with at least four dividing plates 7, form a trumpet-shaped loudspeaker monomer 8 between per two adjacent dividing plates 7.
The course of work of the level 360 degree omnidirectional radiation loud speakers of this kind of version is following: 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 to simultaneously in the formed loudspeaker monomer 8 of upper and lower casing by dividing plate 7 and transaudient housing 6 dishes of omnidirectional, is sent to all directions and gets on; The characteristics of this kind of loud speaker are to utilize a pronunciation source, thereby the omnidirectional sound of realization level 360 degree transmits.
Claims (1)
1. a level 360 is spent the omnidirectional radiation loud speakers; Comprise RP head (1); In RP head (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) top are provided with air chamber conduit (4); Socket is fixed with reflecting drum (5) in air chamber conduit (4) outside, and the inner chamber of reflecting drum (5) is communicated with for the circular transaudient housing of omnidirectional (6) with cross section, and the upper shell of the transaudient housing of omnidirectional (6) and lower house are dish-shaped; In the transaudient housing of omnidirectional (6), be evenly distributed with at least four dividing plates (7), per two adjacent dividing plates (7) are formed horn type loudspeaker monomer (8) with the transaudient housing of omnidirectional (6).
