1 is an exemplary view showing an example of a gap speaker device according to an embodiment of the present invention.

Referring to FIG. 1, a gap speaker device according to an exemplary embodiment may include a first gap speaker 1 and a second gap speaker 2.

The first gap speaker 1 and the second gap speaker 2 output sound according to an audio signal received from the outside, and may be a split-firing speaker system that emits sound through a plurality of gaps. have.

Sides 4 and 6 of the first gap speaker 1 and the second gap speaker 2 may be provided with a plurality of slits 3 and 5 through which sound may be emitted.

The plurality of gaps 3 and 5 are designed to have a thickness smaller than the wavelength of the sound emitted, so that they can function as the origin of the sound emission of the plurality of gaps. For example, the thickness 3 of the plurality of gaps may be designed to be 1/4 or less of 17 mm, which is the wavelength of the audible limit frequency. In addition, the thicknesses 4 and 6 of the first gap speaker 1 and the second gap speaker 2 indicate that the emitted sound is reflected from the side of the first gap speaker 1 or the second gap speaker 2. It can be designed thin enough to be negligible. For example, the thicknesses 4 and 6 of the first gap speaker 1 and the second gap speaker 2 may be designed to be 20 mm or less. The plurality of gaps 3 and 5 may satisfy the ground plane radiation condition.

According to such a design, the first gap speaker 1 and the second gap speaker 2 according to an embodiment of the present invention may satisfy the ground plane radiation condition of emitting sound at a 2π solid angle upward from the wall or the bottom surface. Can be. In this case, since the first gap speaker 1 may be interpreted as being discharged forward from the wall, the wall may be understood as ground, and the second gap speaker 2 may be interpreted as if it is emitted upward from the floor. The bottom surface can be understood as ground. As the first gap speaker 1 and the second gap speaker 2 emit ground plane radiation, the output sound may not be reflected from the rear, and a sound quality of a front-firing level may be secured.

Accordingly, the gap speaker according to an embodiment of the present invention may have an acoustic axis formed upward or forward as satisfying the ground plane radiation condition, and an optimal sweet spot at the center or front side in terms of the vertical orientation. This can be formed. In addition, in the aspect of horizontal orientation, as the ground plane radiation condition is satisfied, a sweet spot may be formed on the front surface widely.

The first gap speaker 1 and the second gap speaker 2 according to an embodiment of the present invention may be spaced apart by a predetermined distance in the vertical direction to output sound of different channels. In this case, the first gap speaker 1 may output a sound having directivity and a sense of altitude, and the second gap speaker 2 may output a sound having no sense of altitude. In the following description, a sound having a sense of altitude that allows the listener to perceive a sense of direction and a sense of space will be referred to as altitude sound. Altitude sound may be signaled by being included in an altitude channel.

Directivity refers to a form in which sound spreads from a sound source, and a sound with a high directivity may go straight to one place without spreading the sound. Therefore, sweet spots for directional sound are generally narrow.

However, as described above, the gap speaker is designed to have a thickness smaller than the wavelength of the emitted sound, so that a sweet spot may be formed in the front such as the origin of the emitted sound. Therefore, when the sound with strong drag is output through the gap speaker, a wide range of sweet spots can be formed.

Since the sound has higher directivity as the frequency is higher, the sound in the high frequency range of the high-frequency sound may be output through the gap speaker 1 located above. Among the high-altitude sounds, the low frequency directivity sound may have low directivity and may have a slight sense of direction or space to the listener. Therefore, the sound in the low frequency range of the sound of the high-channel can be output through the gap speaker (2) located below.

The first gap speaker 1 located above may form an upper layer that outputs altitude sound, and the second gap speaker 2 located below forms a lower layer that outputs sound other than a horizontal channel or altitude sound. can do. The upper layer or the lower layer described above may mean a sweet spot, which may be formed by the gap speaker, respectively.

In this case, the above-described altitude channel may refer to a channel capable of outputting an acoustic signal through a speaker located above the head of the listener so that a sense of altitude can be felt. The horizontal channel may refer to a channel capable of outputting a sound signal through a speaker positioned on a horizontal plane with the listener. The non-altitude sound may be a sound belonging to a horizontal channel, but is not limited thereto, and may include a sound that may be output under a plane.

Since the altitude sound output from the upper layer may be reflected to the ceiling and transmitted to the listener, the listener who hears the sound output from the gap speakers 1 and 2 may feel elevation, space, three-dimensional feeling, and the like.

In FIG. 1, only the gap speakers 1 and 2 forming upper and lower layers are shown, but the present disclosure is not limited thereto, and the gap speakers may be formed on both sides. Accordingly, the gap speaker on the left side may output sound of the left channel, and the gap speaker on the right side may output sound of the right channel. In addition, according to an embodiment of the present invention, not only two clearance speakers but also several clearance speakers may be included.

In the following description, a method and apparatus for outputting sound using a gap speaker designed to have a thickness smaller than the wavelength of the emitted sound and having a sweet spot wide in front such as the origin of the emitted sound may be implemented. Examples will be described.

The gap speaker 200 may be implemented by more components than the illustrated component, and the gap speaker 200 may be implemented by fewer components.

Hereinafter, the components will be described in turn.

The first gap speaker 210 may output a sound of a high frequency band having high directivity among altitude sounds through at least one gap. The directivity sound has a property of going straight, so that the sweet spot may be narrowly formed, but when the sound is output through the gap speaker, the sweet spot may be broadly formed even for the strong directivity sound. The altitude sound output to the upper layer of the first gap speaker 210 may be transmitted to the listener at an overhead position. Therefore, the altitude sound is distinguished from the sound output through the lower layer so that the listener can perceive a three-dimensional feeling, a sense of space, a sense of direction, and the like.

The second gap speaker 220 may output a low frequency sound or a sound other than the high altitude sound among the altitude sounds through the at least one gap.

The first gap speaker 210 and the second gap speaker 220 may form an upper and lower layer to output sound in various directions, without being limited to outputting sound in a downward direction. For example, the first gap speaker 210 and the second gap speaker 220 may be arranged in left and right directions or in a front and rear direction to output sound so that the listener may perceive stereoscopic sound.

In addition, although the gap speaker 200 illustrated in FIGS. 2 and 3 includes the first gap speaker 210 and the second gap speaker 220, the gap speaker 200 is not limited to two gap speakers, and has a different sense of direction. It may include a plurality of gap speaker for outputting sound.

The sensor unit 230 may detect a posture of the gap speaker 200, a position of the user, and generate a sensing signal for controlling the operation of the gap speaker 200. The controller 230 may control the gap speaker 200 according to the sensing signal generated by the sensor 230. For example, the sensor unit 230 may include at least one of a gyro sensor and an infrared sensor.

However, not all illustrated components are essential components. The terminal device 400 may be implemented by more components than the illustrated components, or the terminal device 400 may be implemented by fewer components.

Hereinafter, the components will be described in turn.

The flat panel speaker 440 is a thin plate-shaped speaker, in particular, in the case of a transparent flat speaker, a liquid crystal display, an organic EL display, and a PDP can be mounted on a display 410 that allows a user to visually check information. You can save space. The flat panel speaker 440 according to an exemplary embodiment may be attached to the display 410 and may output sound at a predetermined position on the display 410 by vibrating under the control of the controller 430. Here, the flat panel speaker 440 is a term that typically refers to a flat sound output device, and the flat panel is used in a relative meaning, and may not be a perfect plane.

The flat panel speaker 430 may include a vibration panel and a vibration unit. The vibrating panel is a flat plate that can be mounted on the display 410, and an acrylic plate, glass, plastic, or the like, which is generally mounted to protect the display 410, may be used.

6 to 12, a speaker device designed to have a thickness smaller than the wavelength of the emitted sound, and implemented according to a feature of the gap speaker, in which a sweet spot may be widely formed in front such as the origin of the emitted sound or An example of a terminal device will be described with reference to the illustration of each drawing.

6 and 7 are exemplary diagrams illustrating an example of a terminal device including a gap speaker according to an exemplary embodiment.

Referring to FIG. 6A, a terminal device 600 including a gap speaker may include a plurality of gap speakers 621 to 624, a display 610, flat panel speakers 631 to 634, and a controller (not shown). .

The plurality of gap speakers 621 to 624 may output sound signals corresponding to the image displayed on the display 610 under the control of the controller.

When the size of the display 610 is large, as in the case where the display 610 is an ultra high definition (UHD) display, if the speaker is located only at the bottom as in a general case, the listener hears sound only through the bottom speaker. Difficult to perceive sound That is, the sound generated in the upper region of the image displayed on the display 610, that is, the sound is preferably output through the upper speaker in order to give the listener a stereoscopic sense as generated in the upper region of the image.

Accordingly, the gap speakers 621 to 624 according to an embodiment of the present invention have different gap speakers 621 to 620 at different positions depending on the generation position of the sound on the image displayed on the display 610 to provide a 3D effect to the listener. 624).

For example, the gap speaker 621 may output sound generated in the upper left area of the display 610, and the gap speaker 622 may output sound generated in the upper right area. In addition, the gap speaker 623 may output sound generated in the lower left area, and the gap speaker 624 may output sound generated in the lower right area.

In addition, the upper gap speakers 621 and 622 may output a sound in a high frequency region having strong directivity among sounds generated in the upper region. The lower gap speakers 623 and 624 may output sound generated in a low frequency region or sound generated in a lower region among the sounds generated in the upper region.

In addition, the terminal device 600 may further include flat speakers 631 to 634 for providing a higher stereoscopic feeling to the listener. The flat panel speakers 631 to 634 shown in Fig. 6A show the vibration unit of the flat panel speaker described above.

The flat panel speakers 631 to 634 may output sound by generating vibration in a region where sound is generated. This is to overcome the point that the sound generated in the center area of the display 610 is output far from the area where the sound is generated. In particular, when the display 610 is a UHD display, since the size of the display 610 is large, the sound tends to be output far away from the sound generating region, and the listener is outputted differently from the displayed image. You may feel dissociated. Especially in the case of high frequency sound, since the directivity is strong, the sense of separation can be felt even larger.

For example, referring to FIG. 6A, when speech sounds are output from a mouth of a person displayed on an image, a listener may feel a three-dimensional sense most naturally when speech sounds are output from a displayed “mouth”. The larger the size of the display 610, the greater the tendency to feel natural. To this end, the terminal device 600 according to an embodiment of the present invention can be controlled so that the speech sound can be output from the 'mouth' using the flat panel speakers 631 to 634. In this case, the terminal device 600 may control to output, through the flat panel speakers 631 to 634, the directional sound such as the high frequency sound.

As shown in FIG. 6A, a plurality of gap speakers 621 to 624 are included in the terminal device 600. However, the present disclosure is not limited thereto, and the plurality of clearance speakers 621 to 624 may be coupled to upper and lower portions of the terminal device 600 through the coupling unit.

6B and 6C, the terminal device 600 including a gap speaker may include a plurality of gap speakers 625, 626, 627, and 628, a display 611, 612, and a controller (not shown). have.

The plurality of gap speakers illustrated in FIGS. 6B and 6C may be positioned vertically or horizontally on the top, bottom, left and right sides.

The plurality of gap speakers illustrated in FIG. 6B may be horizontally extended at the upper and lower portions thereof, and the gap speaker 625 positioned at the upper portion may form an upper layer to output sound generated in an upper region of the display 611. In addition, the left and right portions of the upper gap speaker 625 may output sound generated in the upper left or upper right regions, respectively.

In addition, the gap speaker 626 disposed at the lower portion may form a lower layer to output sound generated in the lower region of the display 611. In addition, left and right portions of the lower gap speaker 629 may output sound generated in the lower left or lower right region, respectively.

The plurality of gap speakers illustrated in FIG. 6C may be vertically extended to the left and right, and the gap speaker 627 located on the left may output sound generated in the left region of the display 612. In addition, the upper part and the lower part of the left gap speaker 627 may form an upper layer and a lower radar, and output sound generated in the upper left or lower left area.

In addition, the gap speaker 628 located on the right side may output sound generated in the right area of the display 612. In addition, the upper part and the lower part of the right gap speaker 628 may form an upper layer and a lower radar to output sound generated in the upper right or lower right area.

In addition, the gap speaker may be attached to upper and lower sides or left and right sides according to the size of the display of the displays 610, 611, and 612 to output sound.

For example, in the display having a size of 46 inches, the gap speaker may be horizontally attached to the upper and lower portions of the display in consideration of the small size of the display and the small left and right separation. The gap speaker may output sound generated in the upper and lower regions, respectively. In addition, the display having a size of 60 inches may be attached to the gap speaker perpendicular to the left and right of the display in consideration of the large size of the display and the large left and right separation. The gap speaker may output sound generated in left and right regions, respectively.

The gap speaker attached to the display may set the area of the display to output sound by determining whether the gap speaker is installed horizontally or vertically according to a result detected by the gyro sensor or a user setting. For example, when the gap speaker is horizontally attached to the upper and lower ends, the sound generated in the upper region or the lower region of the display may be output. In addition, when the gap speaker is vertically attached to the left and right sides, the sound generated in the right region or the left region of the display may be output.

In addition, in a curved display, a gap speaker may be vertically attached to the left and right sides as shown in FIG. 6C. Each gap speaker may output sound generated in left and right areas of the display.

The gap speaker according to an embodiment of the present invention may be attached to an appropriate position according to the size or shape of the display to output sound generated in each area of the display according to the position where the gap speaker is attached.

Referring to FIG. 7, the terminal devices 710 to 730 may include gap speakers 711 to 732 at the bottom thereof.

One gap speaker of each terminal device 710 to 730 may be present at each of left and right sides to output sound in left and right directions. In this case, the distance between the spaced speakers in the left and right directions may increase the stereo and space for the output sound.

Therefore, according to an embodiment of the present disclosure, the gap speaker may be disposed such that the gap speakers located at the left and right sides of the terminal devices 710 to 730 are spaced apart in the left and right directions at the maximum. That is, when the gap speaker is not included in the terminal devices 710 to 730, the gap speaker may be arranged to have a maximum separation distance according to the size of the terminal devices 710 to 730, thereby providing stereo and I can maximize a feeling of space.

Although only the gap speaker at the bottom is shown in FIG. 7, the gap speaker located at the top as shown in FIG. 6 may also be arranged to have a maximum separation distance.

In addition, as shown in FIG. 7, a plurality of gap speakers 711 to 732 are included in the terminal device 700. However, the present invention is not limited thereto, and the plurality of gap speakers 711 to 732 may be coupled to upper and lower portions of the terminal device 700 through the fastening unit.
