Description

Speaker {LOUDSPEAKER}

More particularly, the present invention relates to a loudspeaker, and more particularly, to a loudspeaker having a sound path in a loudspeaker, a reflection plate disposed at a portion where a sound path angle is changed, To a speaker having a structure that can be used.

Generally speaking, the sound from the speaker is evaluated as the sound field. The sound field is a comprehensive sound that is heard from the instruments played on the actual stage in the direction of the audience and the sound coming from the back and sides of the stage reflected back to the audience.

Such a sound field can be varied depending on the installation position and arrangement of the speaker, but in the case of a speaker installed in the room, there is a limit to the position and arrangement of the speaker freely due to the space limitation.

Conventionally designed speakers are equipped with a duct inside and the sound coming out to the rear side of the unit goes out through the duct to the front of the speaker so that people can hear the difference in the sound being cut, have.

However, in a conventional duct installed in most speakers, the sound coming out to the rear side of the unit often does not completely go out to the front. This is because the sound path formed in the loudspeaker does not have a uniform width, or the structure of the reflection plate reflecting the sound is not precise, resulting in distortion of the sound.

Korean Patent Publication No. 10-2007-0005856 Korean Utility Model Registration No. 20-0175260 US 4,512,434

SUMMARY OF THE INVENTION It is an object of the present invention to provide a loudspeaker which allows the loudspeaker to fully emerge from a front side of a loudspeaker without interference, overlapping, and resonance of sound inside the loudspeaker.

The present invention aims at providing a speaker which allows a user to hear the sound coming out to the front side of the unit and the sound coming out to the rear side of the unit to the outside of the speaker with a time difference through the inside of the speaker .

The problems to be solved by the present invention are not limited to the above-mentioned problems. It is to be understood by those skilled in the art that the present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof.

A speaker according to a first embodiment of the present invention is a speaker in which a unit for generating a sound is installed inside, the unit is installed horizontally, and sound emitted to the upper side of the unit is reflected by a front reflector provided on the upper side of the unit And the sound emitted to the lower side of the unit passes through the first path and the second path, is reflected by the front reflector and is emitted to the front side, and the sound emitted to the upper side of the unit and the sound emitted toward the lower side The sound passing through the first path and the second path is reflected by the front reflector and is forwarded through the opening OP formed on the speaker, and the second path is longer than the first path.

The speaker according to the second embodiment of the present invention is a speaker in which a unit for generating sound is installed therein. The unit is installed horizontally, and the sound emitted to the upper side of the unit is reflected by a front reflector provided on the upper side of the unit, So that the sound coming out from the lower side of the unit and passing through the first path is reflected by the front reflector and is forwarded through the opening OP formed in the upper part , Sound coming out from the lower side of the unit through the second path is emitted through the opening OP-S formed in the lower part, and the second path is longer than the first path.

The speaker according to the third embodiment of the present invention is a speaker in which a unit for generating sound is installed therein. The speaker is divided into four regions by interposing a diaphragm having vertical incision grooves thereon and a diaphragm having vertical incision grooves therebetween Respectively,

Wherein the diaphragm having vertical cutout grooves is formed of a front partial diaphragm and a rear partial diaphragm, and the diaphragm having vertical cutout grooves at the lower portion is composed of one side partial diaphragm and the other side diaphragm,

Wherein the four regions are an RA region, an RB region, an RC region, and an RD region, and an RA region is formed between the front partial partition and the one partial partition, an RB region is formed between the one partial partition and the rear partial partition, A middle area unit is formed on the upper part of the RA area, and an incident-side reflecting plate is formed on the lower part of the RA area, An incident-side reflector is formed on the lower portion of the RB region, an incident-side reflector is formed on the upper portion of the RB region, an outgoing-side reflector is formed on the upper portion of the RC region, An output-side reflector is formed on the lower portion of the RD region, a high-frequency unit is provided on the upper portion of the RD region, and a front reflector is provided on the upper portion of the high- Sex and the jungjeoyeok unit is installed horizontally.

The speaker according to the present invention is designed so that all the sound coming out to the rear side of the unit by the diaphragm and the reflection plate is directed to the front side of the speaker completely, so that no distortion of the sound that may occur in the inside of the speaker occurs.

Further, by horizontally installing the low-middle-frequency unit in which vibration energy is generated to a large extent, it is possible to prevent the mechanical vibration of the speaker which may appear at the time of vertical installation.

Further, since the mid-range unit of a general vertical installation structure performs back and forth vibrating motion, the front and rear vibrations of the speaker barrel are generated, and the vibration is mixed with the sound generated in the unit to distort the original sound. In the present invention, by installing the low-middle-level unit horizontally, the low-middle-level unit vibrates upward and downward, so that the bottom of the speaker firmly supports the vibration and absorbs the vibration. Therefore, since the vibration of the speaker barrel due to the vibration of the low-middle-frequency unit is not generated, no distortion occurs in generation and transmission of sound.

Also, since the path of the sound coming out to the rear side of the unit is composed of a relatively short path and a relatively long path, the path is shifted to the front side of the speaker with a time difference, so that a sense of presence and richness can be felt.

Also, when the speaker is placed on the floor, the direction toward the person who listens to the sound is referred to as the front side, and the opposite direction is referred to as the rear side.

The speaker is composed of a unit generating a sound, a network composed of electronic circuits, and an enclosure enclosing the unit and the network. In the following description, the network will be omitted.

FIG. 1 is a perspective view of a speaker according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view of a speaker according to a first embodiment of the present invention.

The speaker according to the present invention includes a cover 100, a body 200 and a front plate 300, and a unit including a high-frequency unit U-1 and a low-frequency unit U-2.

The cover 100 has a rectangular shape, and is formed in a box shape in which a space is formed inside and the front side is opened. The body is interposed in the space portion, and the front side of the cover is closed by the front plate (300). When the cover and the front plate are coupled to each other, an opening (OP) through which the sound from the unit is output is formed on the speaker.

The body 200 includes a diaphragm 210 and a reflector 220. And a high-frequency unit (U-1) and a low-frequency unit (U-2) are coupled to the body. Although not shown, a network is coupled to the high-frequency unit and the low-frequency unit, and the network filters the acoustic signals into the high-frequency band and the low-frequency band, and outputs them to the high-frequency unit and the low-

The body comprises a plurality of reflectors and a plurality of diaphragms. And an auxiliary plate may be further provided for fixing the precise position thereof. FIG. 3 is a view showing a state before coupling a plurality of reflectors and a plurality of diaphragms constituting a body to an auxiliary plate, and FIG. 4 shows a body coupled to an auxiliary plate. As described above, the reflector and the diaphragm constituting the body of the auxiliary plate AU may be first fixed and then inserted and fixed in the inner space of the cover.

FIG. 5 (A) is a perspective view of a body according to the present invention, and FIG. 5 (B) is a front view of a body according to the present invention.

Referring to the drawings, a body according to the present invention includes a plurality of reflectors and a plurality of diaphragms combined to form a sound passage from the unit.

In the present invention, a high-frequency unit and a low-frequency unit are mounted on a body. In the case of the high-frequency unit, the vibration energy generated is relatively small as compared with the low-frequency unit. The low-middle-unit outputs the most vibration energy coming from the speaker. When the mid-range unit is installed horizontally, the vibration energy comes out up and down. Most of the conventional middle and low-end units are vertically installed, and vibration energy moving in the front and rear directions is generated. As a result, the speaker is moved and mechanical vibration is generated. Therefore, in the present invention, it is possible to prevent the mechanical vibration by horizontally installing the low-middle-frequency unit.

And the high-frequency unit is coupled vertically to the other side of the low-frequency unit. The high-frequency unit causes the sound to come out to the front.

Referring to the drawings, a lower-end unit and a higher-stage unit are installed on an upper portion of a plurality of combined diaphragms. The low and mid-range units are installed at one upper end of the combined diaphragms, and the high-frequency units are installed at the other side of the combined diaphragms. The diaphragm forms a passage of sound with the cover and the front plate.

The diaphragm 210 includes a first diaphragm 211, a second diaphragm 212, a second diaphragm 213, a second diaphragm 214, a second diaphragm 215, And the lower ends of the first diaphragm 211, the second diaphragm 213, and the second diaphragm 215 form a predetermined distance from the reflector. And the lower end of the separating partition plate 212 and the second-second partition plate 214 are coupled to the bottom. The upper end of the separation diaphragm has a predetermined distance from the lower portion of the middle-low-level unit, and the upper end of the second-second diaphragm is spaced apart from the reflection plate by a predetermined distance.

The reflector 220 changes the course of the sound. The reflection plate includes a first emission-side reflection plate 221-2, a first incident-side reflection plate 221-1, a second-first incident-side reflection plate 222-1, a second- The first to third outgoing reflectors 222-2, the second to third incoming reflectors 222-5, and the second to third outgoing reflectors 222-6 are sequentially formed.

Referring to the drawings, a first exit-side reflector and a first incident-side reflector are formed under the first diaphragm, and a second-1 incident-side reflector and a second-1st exit- And a second-2-3 incident-side reflector and a second-2-3 outgoing-side reflector are formed under the second-third diaphragm.

A second-second incident-side reflecting plate 222-3 and a second-second emitting-side reflecting plate 222-4 are formed below the high-frequency unit. In other words, the 2-2 incident-side reflector and the 2-2 outgoing-side reflector are formed on the upper end of the 2-2 diaphragm 214.

Also, a front reflector 223 is formed on the upper portion of the body (upper side of the high-frequency unit and the middle-low-frequency unit). The front reflector reflects the sound coming from the upper side and the lower side of the middle-sized unit to the front side of the speaker through the opening part OP.

Fig. 6 is an enlarged view of a circular portion indicated by X in Fig. 5 (B), and Fig. 7 shows an incident-side reflector and an exit-side reflector according to the present invention.

Referring to FIG. 7, the reflector 220 includes an incident side and an emission side reflector for changing the traveling path of the sound emitted from the low-end unit, and a front reflector for finally emitting sound to the outside of the speaker.

7 (A) shows an incidence-side reflector, which is a wedge-like shape in which a surface to be reflected is a curved surface so as to be seated on a corner formed at a right angle. And Fig. 7 (B) shows the outgoing reflector. The outgoing reflector is a wedge shape in which the reflecting surface is curved.

The incident-side and emission-side reflectors thus formed are installed at a portion where the sound path is to be changed.

FIG. 6 shows an incident-side reflector and an outgoing-side reflector provided in a region where sound propagation direction is changed.

The incident-side reflector and the outgoing-side reflector are connected in series, and the incident-side reflector and the outgoing-side reflector, which are coupled in succession, have a concave shape with a high outside portion and a low center portion. Referring to the drawings, the incident-side reflector is formed such that the length WI of the bottom surface is longer than the height HI, and the outgoing-side reflector has a height HO higher than the length WO of the bottom surface.

An end of the diaphragm is located at a position facing the incident side and the outgoing side reflector coupled to each other successively. The edge of the diaphragm is formed to be equal to the height of the incident-side reflection plate for smooth sound reflection. One side of the diaphragm on the basis of the diaphragm is a path of sound to be incident, and the other side of the diaphragm is a path of sound to be emitted.

Hereinafter, it will be explained with reference to FIG. 8 that the sound path is changed by the reflection plate and the diaphragm. 8 shows a sound path by the reflector and the diaphragm.

Referring to the drawing, D1 coming into the incident-side reflector is reflected from the outermost side of the incident-side reflector, then reflected again from the center of the outgoing-side reflector, and goes to S1. Therefore, the height of the edge of the diaphragm should be at least the same as the height of the outside of the incident-side reflector.

D2 and D3 coming into the incident side reflector are reflected from the lower part of the incident side reflector and then reflected again from the higher part of the outgoing side reflector to S2 and S3. The focal point P of the incident-side reflection plate having such a curvature shape is formed at the exit-side corner portion of the diaphragm end formed at the center.

Fig. 9 shows a path of sound coming from the lower side of the middle-low-level unit.

Referring to the drawing, sound emitted from the lower side of the low-middle-frequency unit is divided into two sides by the separation diaphragm 212 and travels with different paths. This path may be referred to as a first path and a second path, wherein the first path is formed shorter than the second path.

The first path (C) descends between the first diaphragm and the separating diaphragm, and after being reflected to return the traveling direction from the first incident-side reflecting plate and the first emitting-side reflecting plate, the first path (C) As shown in Fig.

The second path (D) descends between the separation diaphragm and the second-1 diaphragm, and is reflected by the second-first incident-side reflector and the second-first emission- And rises between the diaphragms. Then, after being reflected by the second and third incident-side reflectors and the second and second outgoing reflectors, the light is lowered between the second and second diaphragms and the second and third diaphragms, and then the second and third incident- Side reflecting plate and then raised between the second and third diaphragms and the side plate formed on the other side of the cover.

When the length between the first path and the second path is referred to as a unit length (SL), the length between the incident-side reflector and the incident-side reflector in the outgoing- 2 × SL, and the second path becomes 4 × SL. Thus, the second path is approximately twice the first path.

FIG. 10 is a view showing a general path of sound emitted from a speaker according to the present invention.

First, the high-frequency unit is installed perpendicular to the opening (OP), and the sound from the high-frequency unit directly goes to the person in front of the speaker.

The low-middle-level unit is installed horizontally. Here, the term "vertical installation" means that the sound output side of the unit is raised, and "horizontal installation" means that the sound output side of the unit is directed upward. The sound coming from the upper side of the medium-range unit is reflected by the front reflector and goes to the front side of the speaker through the opening.

Then, the sound coming from the lower side of the middle-low-range unit goes through the first path and the second path as described above. Sound that has passed through the first and second paths is reflected by the front reflector and travels forward through the openings.

Thus, the sound from the high-end unit is directed directly to the front of the speaker, and the sound from the low-end unit forms three paths. That is, sounds coming out to the upper side of the middle-range unit and sounds coming out the lower side of the middle-level unit and passing through the first and second paths. Sounds with these three paths form different lengths. The person facing the speaker can feel the sound of the sound because the sound from the high-frequency unit and the sound of the three paths from the low-end unit are mixed and heard at a time interval.

11 to 13 show a speaker according to the second embodiment.

Referring to Fig. 11 (A), an opening OP-S is formed below the back surface of the speaker. 11 (B) is an inner view of FIG. 11 (A). Like the first embodiment described above, the first path is the same, but the second path is formed shorter. The second path according to the second embodiment descends between the separation diaphragm and the second-1 diaphragm, then rises between the second-1 diaphragm and the 2-2 diaphragm, and then, on the other side of the second- The sound is emitted through the opening formed below the back surface of the cover after descending between the formed side plates. FIG. 12 is a three-dimensional view showing that the sound passing through the second path passes through an opening provided on the back surface of the cover.

Normally, the speaker is usually installed closely to the wall, so that the sound coming from under the back of the speaker is reflected by the wall and goes to the front of the speaker.

13 (A), an opening is formed on the other side of the lower side of the front plate 300, and Fig. 13 (B) shows an opening formed on the other side of the lower side of the side plate of the cover 100. Fig. The embodiment shown in FIG. 13 differs from the embodiment shown in FIG. 11 and FIG. 12 in the installation direction of the last reflector and the position of the opening.

11 to 13, the sound coming out of the upper side of the low-frequency unit and the sound passing through the first path outwardly of the low-frequency unit are reflected by the front reflector, And the sound coming out from the lower side of the low-middle-frequency unit and passing through the second path is outputted through the opening OP-S provided separately.

14 to 16 show a speaker according to the third embodiment.

14 and 15, a diaphragm 501 having vertical incision grooves at the upper center and a diaphragm 502 having vertical incision grooves at the lower center are vertically interdigitated and divided into four regions. Fig. 15 (C) is a plan view as viewed in the direction of the arrow in Fig. 15 (A). Referring to FIG. 15 (C), the four regions are R-A region, R-B region, R-C region, and R-D region. The R-A region and the R-B region are located on the front side, and the R-C region and the R-D region are located on the rear side. 15 (A) and 15 (B), when two diaphragms 501 and 502 are coupled to each other in the vertical cutout grooves, some are joined and some are not. Accordingly, when the two coupled diaphragms are installed, a predetermined gap is formed between the lower end of the diaphragm coupled to the upper side and the ground.

For convenience of explanation, it is assumed that the diaphragm 501 having a lower end portion on the ground is divided into two parts vertically (divided in half) to form a front partial partition 501a and a rear partial partition 501b. Will be described as being composed of one side partial partition 502a and the other partial partial partition 502b vertically halved.

Therefore, the area between the front partial partition plate 501a and the one partial partial partition plate 502a becomes the RA area, the area between the one partial partition plate 502a and the rear partial partition plate 501b becomes the RB area, The area between the other partial partition 502b is an RC area, and the area between the other partial partition 502b and the front partial partition 501a is an RD area.

Referring to FIGS. 16A to 16C, an intermediate unit is formed on the R-A region, and an incident-side reflection plate 601 is formed on the lower portion of the R-A region. An outgoing-side reflector 602 is formed under the R-B region and an incident-side reflector 603 is formed in an upper portion of the R-B region.

An outgoing reflector 604 is formed on the R-C region, and an incident-side reflector 605 is formed on the bottom of the R-C region. An output-side reflector 606 is formed under the R-D region, and a high-frequency unit is provided at an upper portion of the R-D region.

A front reflector 607 is formed on the upper portion of the high-frequency unit and the low-frequency unit.

Referring to the drawing, the sound coming out to the upper side of the low-middle-frequency unit is reflected by the front reflector and then exits to the front side through the opening part OP, the sound coming out to the lower side of the low- Area, rises in the RD area, is finally reflected on the front reflector, and then exits through the opening part OP to the front side.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the present invention is not limited to the disclosed exemplary embodiments, but various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention.
