Description

TECHNICAL FIELD [0001] The present invention relates to a three-dimensional sound guide for a speaker,

The present invention relates to a stereophonic sound guide for a speaker and a speaker having the same.

More specifically, the present invention uses a sound-guiding stereophonic sound guide provided inside a horn constituting a speaker, or a combination of a sound-guiding stereophonic sound guide and a sound-impermeable material stereophonic sound guide , The sound passing through the inner guide groove of the horn and the sound passing through the arbitrary path passing through the inside of the sound-guiding material of the sound-permeable material all have the same time transmission path, so that a substantial plane wave is formed outside the horn , The structure of the stereo sound guide and the speaker is very simple and simplified, the manufacture of the speaker is very easy, the manufacturing cost is significantly reduced, and the sound transmitted through the speaker forms a substantial plane wave, , And a speaker system combining a plurality of speakers is used It is possible to prevent the occurrence of an interference phenomenon even in a portion where the sound generated by each speaker overlaps with each other. For example, a stereophonic sound guide for a speaker can be sufficiently transmitted regardless of the position of a viewer in a performance hall and a speaker will be.

In general, a speaker is a device for converting electric energy into physical energy to reproduce sound, and outputs sound or sound according to a sound source.

Such a speaker is classified into a dynamic speaker, a moving speaker, an electrostatic speaker, a ribbon speaker, and a piezoelectric speaker by a reproducing method. Speakers and so on.

Also, in a concert hall such as a concert hall or the like, a line speaker system is used, which is a large speaker in which a plurality of speakers are connected in series in one direction (for example, up and down) in order to maximize the performance effect. In a speaker system in which a speaker or a plurality of speakers are continuously arranged, a method of increasing the sound pressure to send sound far away is used. To realize this, a horn-type speaker (hereinafter referred to as "horn speaker") is used. These horn speakers consist of a horn and a compression driver. The compression driver can be implemented to reduce the air resistance when the diaphragm is moving, thus achieving high sound pressure.

In addition, the horn guides the spread of the sound generated by the compression driver, and the frequency range is determined by the size and shape of the horn. Generally, the size of the horn becomes small when guiding a high frequency band and becomes large when guiding a low frequency band. For example, when designing a horn for controlling a frequency up to 100 Hz, a horn having a size corresponding to a quarter wavelength of a wavelength corresponding to 100 Hz is required. Also, in the case of a speaker system, the shape of a horn is determined when a treble sound is to be transmitted in a specific direction (right or left or up and down).

On the other hand, the sound generated by the compression driver is propagated into the air through the horn. In this case, the horn typically has a trumpet shape, so that it has innumerable paths along the inner space of the horn and horn that are transmitted along the inner surface of the horn. If we visualize the trajectory of sound passing through many different paths, we have different trajectories as the path difference, and propagate while forming spherical wave form. For example, in a speaker system in which a plurality of speakers used in a large concert hall or the like are continuously arranged, a plurality of sounds transmitted in the form of a square wave along a plurality of horns cause an interference phenomenon to mutually cancel (cancel) There is a problem that it is difficult to transmit a desired sound to a listener at a specific position due to interference. Further, when the interference phenomenon becomes worse, the sound can not be transmitted to far away, which causes a problem that the sound effect remarkably drops in a wide indoor space or outdoors.

As one of the measures for solving the problem of the spherical wave generation described above, a planar acoustic guide for realizing a plane wave instead of a spherical wave, and a speaker and a speaker system having the same, have been proposed and used.

More specifically, FIG. 1A is an exploded perspective view of a conventional planar acoustic guide, and FIG. 1B is an assembled perspective view of a conventional planar acoustic guide. Such prior art planar acoustic guides are described, for example, in Marcosys Cedek, 91462, Park de la Fontaine de Joebbins, Rue Levacher Cintrat, Parc de la Fontaine de Jouvence, 91462 Marcoussis Cedex, L-Acoustics, Inc. (phone number: +33 (0) 1 69 63 69 63, website: www.l-acoustics.com ). Also, a sound guide similar in principle to the prior art planar acoustic guides shown in FIGS. 1A and 1B is known, for example, by Christian Heil on Feb. 28, 1989 as "sound wave guide Quot ;, filed as U.S. Patent Application No. 316,919, and U.S. Patent No. 5,163,167, issued November 10, 1992, which is incorporated herein by reference in its entirety.

Referring to FIGS. 1A and 1B, the conventional planar acoustic guide 10 is implemented as a pair of guide members 10a and 10b having a symmetrical shape. The pair of guide members 10a and 10b are respectively connected to the upper flat plate member 12 and the lower fixing member 14 and to the vertical connection member 16 for connecting the upper flat plate member 12 and the lower fixing member 14 ). The vertically connecting members 16 of the pair of guide members 10a and 10b are each formed with an inverted triangular recessed portion on the inner side surface and a cross section is formed in the center of the recessed portion in the shape of diamond or oblong (Hereinafter referred to as "diamond shape"). A second diamond-shaped protrusion 22 having a length corresponding to half of the length of the upper slope is provided on the upper slope of the central protrusion 20 so as to be spaced apart from the center protrusion 20. A third protruding portion 24 of diamond-like shape having a length corresponding to half of the length of the upper inclined surface is provided on the upper inclined surface of the second protruding portion 22 apart from the second protruding portion 22. Further, on the upper inclined surface of the third projection 24, a diamond-shaped fourth projection 26 having a length corresponding to half of the length of the upper inclined surface is provided apart from the third projection 24. At this time, the upper portions of the diamond-shaped fourth protrusions 26 are all located at the same height as the upper flat plate member 12. The outer lower inclined surfaces of the central projected portion 20 and the second projected portion 22 and the outer lower inclined surfaces of the third projected portion 24 and the fourth projected portion 26 located at the outermost portion are formed in an inverted triangular shape And is provided spaced apart from the side step portion of the recessed portion.

A plurality of fastening holes 18 are provided in a pair of vertical connecting members 16 of the pair of guide members 10a and 10b described above and a pair of guide members 10a and 10b Are coupled to constitute the planar acoustic guide 10. Also, a plurality of second fastening holes 19 are provided in the pair of lower fixing members 14, respectively, and fastened on, for example, a compression driver (not shown).

In the conventional planar acoustic guide 10 as described above, the central projecting portion 20, the second projecting portion 22, the third projecting portion 24, and the third projecting portion 24 provided in the spacing space and the recessed portion from the side stepped portion of the recessed portion, A plurality of planar guide grooves Pa and Pb are formed through which the spacing space between the upper and lower side slanting portions between the fourth projections 26 transmits sound. The planar acoustic guide 10 of the prior art shown in Fig. 1A is provided with eight fourth protrusions 26 at the top, so that the plurality of planar guide grooves Pa and Pb are provided with 16 shortest paths having the same distance do. Therefore, the sound generated in the compression driver (not shown) travels the same distance even when it is transmitted through the first shortest path P1 and the second shortest path P2 which are mutually different shortest paths. Therefore, Since the spherical wave can be formed through the upper flat plate member 12 provided at the same position as the upper portion of the upper plate member 26, no negative interference phenomenon occurs and the sound can be transmitted far.

However, the above-described prior art flat acoustic guide 10 still has the following problems.

More specifically, FIG. 1C is a front view of a line speaker system in which speakers constructed of a pair of horn speakers providing a middle tone and a planar acoustic guide providing a treble provided between the pair of speakers are vertically stacked, and FIG. 1D is a view for explaining a problem of the speaker and line speaker system shown in FIG. 1C, FIG. 1E is a view for explaining a problem of the case where the two line speaker systems shown in FIG. 1C are arranged in the horizontal direction Fig.

1C and 1D, a speaker 100 according to the related art includes a pair of horn loudspeakers 30 for providing a middle sound and a pair of horn loudspeakers 30 And a planar acoustic guide 10. This planar acoustic guide 10 is implemented with the planar acoustic guide 10 shown in Figs. 1A and 1B.

The line speaker system 101 according to the related art includes a plurality of speakers 100 (four in the embodiment shown in FIGS. 1C and 1D) according to the above-described conventional technique stacked in the vertical direction.

In the speaker 100 and the line speaker system 101 according to the conventional art described above, a treble region SA is formed which forms a plane wave without phase difference through the fourth projection 26 in each planar acoustic guide 10 . At this time, the high-frequency area SA does not cause interference along the vertical direction V, but the width of the high-frequency area SA along the horizontal direction H is very narrow, It is very narrow. Concretely, in the speaker 100 and the line speaker system 101 according to the conventional art shown in Figs. 1C and 1D, a narrow range of about 90 degrees in the vertical direction and a narrow range of about 10 degrees in the vertical direction Can be realized. Of course, when the speaker 100 and the line speaker system 101 according to the related art are rotated 90 degrees clockwise or counterclockwise, for example, the range is approximately 90 degrees in the horizontal direction and approximately 10 degrees in the vertical direction. It is possible to realize a narrow range of plane waves within and outside the region.

Therefore, in a wide space such as a theater or a playground having a wide sound transmission range in the horizontal direction and the vertical direction, the sound can be transmitted in either the horizontal direction or the vertical direction, but in the other direction, A dead region is generated in a space or place other than the directional angle range where no sound is transmitted. Due to such a problem, the above-described prior art line speaker system 101 can not be practically used individually in a wide space or place. Thus, while one speaker can be used individually, for example, a plurality of speakers can be provided in a wide space or place by a continuous arrangement such as a left-right and up-down direction, a diagonal direction, a circular arrangement, an annular arrangement, It is necessary to implement a speaker system that does not use a speaker system.

Further, in order to solve the above-mentioned problem, it is possible to increase the depth of the inverted triangular shaped recess provided on the inner surface of the vertical connecting member 16 of the pair of guide members 10a, 10b shown in Figs. 1A and 1B And the projection height of each of the central protrusion 20, the second protrusion 22, the third protrusion 24 and the fourth protrusion 26 is increased, the planar acoustic guide 10 has a plurality of planes The guide grooves Pa and Pb increase in length in the depth direction of the concave portion so that the negative distances passing through the sixteen shortest paths of the plurality of planar guide grooves Pa and Pb are not the same. As a result, there occurs a phase difference between the sound (treble) transmitted through the fourth projection 26 and a problem that the wavefront of the plane wave transmitted through the high-frequency region SA is distorted or distorted and interference occurs.

On the other hand, referring to FIG. 1E, a line speaker system 101 in which first and second line speaker systems 101a and 101b are arranged in a horizontal direction is shown to provide a wide sound transmission range in a horizontal direction. In this line speaker system 101, the first and second linear speaker systems 101a and 101b form a plane wave without phase difference through the fourth projection 26 in the respective planar acoustic guides 10 of the first and second line speaker systems 101a and 101b. And second treble regions SA1 and SA2, respectively. In this case, the first and second treble regions SA1 and SA2 do not generate interference along the vertical direction V, but the width of the treble region SA is very narrow along the horizontal direction H The width of the area where no interference occurs is very narrow. Since the first treble region SA1 and the second treble region SA2 are spaced apart by the pair of horn speakers 30 providing the middle tone, And the second treble sound area SA2 are transmitted through different sound sources. This phenomenon occurs even if another line speaker system in which three or more line speaker systems are arranged in the horizontal direction is used.

In addition, the above-described conventional planar acoustic guide 10, the speaker 100 having the same, and the speaker system 101 have a complicated structure, which makes it difficult to manufacture a speaker and a manufacturing cost is high.

Accordingly, there is a need for a new method for solving the problems of the conventional flat acoustic guide 10, the speaker 100 and the speaker system 101 according to the related art.

2A and 2B are a perspective view and a sectional view of a stereophonic sound guide and speaker for a speaker according to a first embodiment of the present invention, respectively.

2A and 2B, a stereo acoustic guide 220 for a speaker according to a first embodiment of the present invention is provided inside a circular or elliptic horn 210, and a lower portion 220v is provided inside the circular or elliptic horn 210. [ Cone shape having a curved surface corresponding to the inner surface of the circular or elliptic horn 210 to provide a guide groove 212 as a passage through which the sound is transmitted, And the upper portion 220u has a round surface and the rim portion 220e where the upper portion 220u and the lower portion 220v of the speaker's stereo acoustic guide 220 meet, Wherein the speaker is configured to be in contact with an upper portion of an inner side surface of the speaker, and the speaker's stereo acoustic guide (220) is made of a sound permeable material through which the sound can pass, An arbitrary signal transmitted through the inside of the acoustic guide 220 (A-A plane) with respect to the peak point of the round-shaped surface.

Also, the speaker 200 according to the first embodiment of the present invention includes a circular or elliptic horn 210; A stereo acoustic guide 220 for a speaker provided inside the circular or elliptical horn 210; And a driver 230 provided at a lower portion of the circular or elliptical horn 210 and having a sound source diaphragm 240 for generating sound. The stereo acoustic guide 220 for a speaker may include a speaker 220, The present invention is embodied as a stereophonic sound guide 220 for a speaker according to the first embodiment.

In the speaker 200 according to the first embodiment of the present invention, the rim portion 220e where the upper portion 220u and the lower portion 220v of the three-dimensional acoustic guide 220 for a speaker meet is a circular or elliptic horn 210). ≪ / RTI > The lower portion 220v of the stereo sound guide 220 for speakers and the circular or elliptic horn 210 are fastened by a plurality of fastening members 214. [

The sound source diaphragm 220 and the loudspeaker 200 according to the first embodiment of the present invention may include a sound source diaphragm (not shown) built in the driver 230 provided below the circular or elliptic horn 210, P2, P3, P4, and P5 (refer to P1, P2, P3, P4, and P5) are transmitted through the guide groove 212 and the inside of the speaker- ). Although FIG. 2B is illustratively illustrated as having five paths through which notes are passed, it will be appreciated by those skilled in the art that there are a myriad of paths through which notes can pass.

2B, the sound passing through the P1 path has the longest path along the guide groove 212, and the sound passing through the P1 guide is the longest in the sound guide 220 for speakers The sound transmitted through the guide groove 212 and the sound transmitted through the inside of the speaker for the speaker are in the middle respectively and the sound transmitted through the P5 path The path through which the sound is transmitted is the shortest along the guide groove 212 and is transmitted through the interior of the three-dimensional acoustic guide 220 for speakers is the longest.

In the meantime, the speaker's stereo sound guide 220 implemented as a sound-permeable material has a large number of voids (not shown) formed in the sound-permeable material (voids in a foamed material, or a rigid- And the sound is transmitted through the inside of the cavity to generate diffuse reflection, and the sound is transmitted through the surface of the upper portion 220u from the lower portion 220v of the speaker's stereo sound guide 220 to the circular or elliptical shape through the surface of the upper portion 220u. And propagates to the outside of the horn 210.

Therefore, considering the sound transmission rate (approximately 340 m / sec) at room temperature and the characteristics of the sound transmission material (that is, the size of the pores and the uniformity of the pores) constituting the three-dimensional acoustic guide 220 for speakers, The sound transmitted along the P1, P3, and P5 paths is transmitted at the same time with respect to the plane (AA plane) with respect to the peak of the rounded surface of the upper portion 220u The shapes of the upper portion 220u and the lower portion 220v can be calculated.
