1D, in the prior art, the bass loudspeakers 11 and 110 have the first diaphragm 117 having a large horn shape, whereas the treble speakers 13 and 120 have the second diaphragm 127 having a relatively small convex curved shape Respectively. 1D, the treble produced by the treble speakers 13 and 120 spread along the second frame 121 along the directional angular range (and accordingly, a relatively narrow range). In this case, when the speaker shown in Fig. 1D is used singly, there is no interference. However, when a line array speaker system in which a plurality of speakers are arranged vertically or horizontally adjacent to each other is used, / Treble having a high frequency is characterized in that mutual interference phenomenon is generated well between different high tones generated from a plurality of speakers. For example, in a place such as a wide venue, a treble sound is not transmitted to a specific location or sounds weakly A problem arises.

More specifically, FIG. 1E is a view schematically showing a high-frequency propagation state in the case of using a line speaker system in which a plurality of coaxial speakers of the prior art are connected in one direction. Although a line speaker system in which three coaxial speakers are arranged in line is exemplarily shown in Fig. 1E, it is obvious that two or four or more coaxial speakers can be used.

Referring to FIG. 1E, in the prior art line array speaker system, treble generated from each coaxial speaker is spread along each second frame 121 as shown in FIG. 1D. In this case, since the diaphragm 127 of each treble speaker 120 is spaced apart from each other, the high-frequency wavefronts WF1, WF2 and WF3 generated by the respective diaphragm 127 overlap each other. In this case, CI (Constraint Interference) occurs at a position where the treble wave has no path difference or an even number of half waves, whereas at a position where the treble wave has an odd multiple of a half wavelength, destructive interference (DI : destructive interference occurs. Thus, for example, in the case of using the conventional line speaker system shown in Fig. 1E in a performance hall, there is a problem that a treble sound is not delivered or is weakly heard to an audience at a position where destructive interference (DI) occurs.

Therefore, there is a need for a new method for solving the problems of the above-described conventional techniques.

FIG. 2M is a view showing propagation states of high-frequency waves generated by a plurality of lattice-type speakers used in the lattice array speaker system according to the first and second embodiments of the present invention shown in FIGS. 2K and 2L, respectively.

Referring to FIG. 2M with FIGS. 2A through 2J, each of the tweeter horns 227 of a plurality of lattice-type speakers 220 used in the lattice array speaker system 201 according to the first and second embodiments of the present invention, Is provided on the rectangular portion 217a of the woofer horn 217 so that a high frequency wavefront WF propagating along the plurality of tweeter horns 227 is shown in Fig. Thereby forming substantially one plane wave as shown in Fig. Thus, unlike the prior art shown in FIG. 1E, interference between a plurality of treble sounds transmitted through a plurality of tweeter horns 227 does not substantially occur.

As described above, in the lattice-type speaker 200 and the lattice array speaker system 201 according to the embodiment of the present invention described in detail with reference to Figs. 2A to 2M, in particular, in the lattice array speaker system 201, The lattice-type loudspeaker 200 has a directivity angle, so that the transmission distance and range of the high and low sounds generated by the lattice-type speaker 200 are considerably increased, so that the problem of the related art in which high sound is not transmitted or weakly transmitted can be solved.

In addition, the lattice-type speaker 200 collects the sound in a certain direction, and the transmission distance and range of the treble and bass are considerably increased. As a result, it is possible to form a sound field which is wide in the overall sound transmission distance as compared with the related art, and can be transmitted far, so that a sound effect can be obtained in a wider space.

In addition, the lattice horn used in the lattice-type speaker 200 can increase the length in the lateral and longitudinal direction and the depth direction in the outside, thereby enabling the use of a large-sized lattice horn. As a result, the lower limit frequency of the lowest tone of the highest tone region can be further lowered, and a higher sound pressure can be provided, thereby enabling more clear midrange and higher tone reproduction.

In addition, when the lattice array speaker system 201 of the present invention is used, the wavefront forms substantially one plane wave at a portion where the high-frequency sounds generated in each of the plurality of lattice-type speakers 200 are overlapped, Thus, for example, treble can be sufficiently transmitted regardless of the location of the audience in a venue.
