Description

Display and Speaker

[0001] The present invention relates to a display device and a speaker.

[0002] There are games that support multi-channel audio. In these games, sound is output using a surround system, allowing the player to recognize people and objects behind them in the game by the sound they hear (see, for example, Patent Document 1).

[0003] Japanese Patent Application Laid-Open No. 2005-303945

[0004] However, a surround system requires multiple speakers to be placed in a room. In particular, to recognize people or objects behind the player in the game by sound, sound must be output from behind the user in the room, and speakers must be placed behind the player in the room.

[0005] One example of a problem to be solved by the present invention is to make it possible to recognize sounds generated in various directions.

[0006] In order to solve the above problem, the invention described in claim 1 is a display device having an audio signal output unit that outputs multiple audio signals based on multi-channel audio data, multiple light-emitting units that correspond one-to-one to the multiple audio signals, and a control unit that controls the light emission of the multiple light-emitting units, wherein the control unit controls the light emission of each of the multiple light-emitting units based on the audio signal corresponding to that light-emitting unit.

[0007] A tenth aspect of the present invention is a speaker having the above-described display device.

FIG. 3 is a diagram showing an example of a plurality of light-emitting units 120 corresponding to the audio output unit 110 shown in FIG. 2. FIG. 4 is a diagram showing an example of a plurality of light-emitting units 120 corresponding to the audio output unit 110 shown in FIG. 2. FIG. 5 is a diagram explaining an example of the relationship between the volume value of an audio signal and a light-emitting area. FIG. 6 is a diagram explaining an example of the relationship between the volume value of an audio signal and a light-emitting area.

[0009] A display device according to one embodiment of the present invention includes an audio signal output unit that outputs multiple audio signals based on multi-channel audio data, multiple light-emitting units that correspond one-to-one to the multiple audio signals, and a control unit that controls the light emission of the multiple light-emitting units, wherein the control unit controls the light emission of each of the multiple light-emitting units based on the audio signal corresponding to that light-emitting unit. In this embodiment, each of the multiple light-emitting units corresponds to the position of a speaker corresponding to the audio signal corresponding to that light-emitting unit, i.e., the direction in which the sound of the audio signal corresponding to that light-emitting unit is generated. Therefore, in this embodiment, the light emission of a light-emitting unit indicates that sound is generated in the direction in which the sound of the audio signal corresponding to that light-emitting unit is generated. Therefore, in this embodiment, a user can recognize the sound generated in each direction based on the light emission of the light-emitting units.

[0010] The light emitting patterns and / or light colors of the plurality of light emitting units may be different for each of the light emitting units, which makes it easier for the user to recognize the direction from which sound is coming.

[0011] The control unit may be configured to control the size of the light-emitting area of ​​each of the plurality of light-emitting units based on the audio signal corresponding to that light-emitting unit, thereby enabling the user to recognize the type of sound corresponding to that light-emitting unit based on the size of the light-emitting area of ​​that light-emitting unit.

[0012] The control unit may be configured to control the width of the light-emitting area of ​​each of the plurality of light-emitting units based on the audio signal corresponding to that light-emitting unit, thereby enabling the user to recognize the type of sound corresponding to that light-emitting unit based on the width of the light-emitting area of ​​that light-emitting unit.

[0013] The control unit may be configured to control the light emission intensity of each of the plurality of light-emitting units based on the audio signal corresponding to the light-emitting unit, thereby enabling the user to recognize the type of sound corresponding to the light-emitting unit based on the brightness of the light-emitting area of ​​the light-emitting unit.

[0014] The plurality of audio signals may be audio signals that have been subjected to a predetermined gain adjustment, thereby making it possible to emphasize a specific sound.

[0015] The display device may further include an input unit that receives input from a user, and the predetermined gain adjustment may be set based on the input from the input unit. In this way, it is possible to emphasize a sound desired by the user.

[0016] The multi-channel audio data is 7.1ch audio data, and the audio signal output unit generates an audio signal for a left front speaker, an audio signal for a right front speaker, an audio signal for a left surround speaker, an audio signal for a right surround speaker, an audio signal for a left surround back speaker, and an audio signal for a right surround back speaker based on the multi-channel audio data, and outputs a left rear audio signal which is an audio signal obtained by mixing the audio signal for the left front speaker, the audio signal for the right front speaker, the audio signal for the left surround speaker, and the audio signal for the left surround back speaker, and a right rear audio signal, which is an audio signal obtained by mixing an audio signal for a left front speaker with an audio signal for a right front speaker, the plurality of light-emitting units including a left front light-emitting unit corresponding to the audio signal for the left front speaker, a right front light-emitting unit corresponding to the audio signal for the right front speaker, a left rear light-emitting unit corresponding to the left rear audio signal, and a right rear light-emitting unit corresponding to the right rear audio signal, and the control unit controls the light emission of the left front light-emitting unit based on the audio signal for the left front speaker, the light emission of the right front light-emitting unit based on the audio signal for the right front speaker, the light emission of the left rear light-emitting unit based on the left rear audio signal, and the light emission of the right rear light-emitting unit based on the right rear audio signal. In this embodiment, each of the plurality of light-emitting units corresponds to the position of the speaker corresponding to the audio signal corresponding to that light-emitting unit, i.e., the direction in which sound from the audio signal corresponding to that light-emitting unit is generated. Therefore, in this embodiment, the light-emitting unit emitting light indicates that sound is generated in the direction in which sound from the audio signal corresponding to that light-emitting unit is generated. Therefore, in this embodiment, the user can recognize sounds occurring in each direction based on the light emitted by the light emitting section.

[0017] The right front light emitting unit is disposed to the right of the left front light emitting unit, the left rear light emitting unit is disposed below the left front light emitting unit, and the right rear light emitting unit is disposed below and to the right of the left front light emitting unit, making it easier for the user to recognize the direction from which sound is coming.

[0018] A speaker according to an embodiment of the present invention includes the display device, which allows a user to recognize sounds occurring in various directions based on the light emitted by the light-emitting portion.

[0019] 1 is a diagram showing a display device 100 according to an embodiment of the present invention. The display device 100 includes an audio signal output unit 110, a plurality of light-emitting units 120, and a control unit .

[0020] The audio signal output unit 110 outputs multiple audio signals based on the multi-channel audio data. The multi-channel audio data includes three or more pieces of audio data, and in particular includes audio data output from speakers arranged behind the user. The multi-channel audio data is, for example, 5.1ch audio data or 7.1ch audio data. In this case, the audio signal output unit 110 may output audio signals with the same number of channels as the multi-channel audio data, or may output audio signals with fewer channels than the multi-channel audio data, as shown in FIG. 2 .

[0021] Fig. 2 is a diagram showing an example of the audio signal output unit 110. The audio signal output unit 110 has a decoder 111. Furthermore, as shown in Fig. 2, the audio signal output unit 110 may have one or more mixers 112. In the example shown in Fig. 2, the audio signal output unit 110 has two mixers 112A and 112B.

[0022] The decoder 111 generates and outputs audio signals for each speaker based on the multi-channel audio data. In the example shown in Fig. 2, the multi-channel audio data is 7.1ch audio data. Therefore, in the example shown in Fig. 2, the decoder 111 generates and outputs an audio signal LFS for the left front speaker, an audio signal RFS for the right front speaker, an audio signal LSS for the left surround speaker, an audio signal RSS for the right surround speaker, an audio signal LSBS for the left surround back speaker, and an audio signal RSBS for the right surround back speaker.

[0023] The mixer 112 mixes at least some of the audio signals for each speaker output from the decoder 111, and outputs at least some of the multiple audio signals output by the audio signal output unit 110. In the example shown in Fig. 2, the audio signal output unit 110 includes a mixer 112A that mixes an audio signal LSS for the left surround speaker and an audio signal LSBS for the left surround back speaker and outputs a left rear audio signal LRS, which is the mixed audio signal, and a mixer 112B that mixes an audio signal RSS for the right surround speaker and an audio signal RSBS for the right surround back speaker and outputs a right rear audio signal RRS, which is the mixed audio signal. In the example shown in Fig. 2, the audio signal output unit 110 outputs four audio signals: an audio signal LFS for the left front speaker, an audio signal RFS for the right front speaker, a left rear audio signal LRS, and a right rear audio signal RRS.

[0024] The plurality of light-emitting units 120 correspond one-to-one to the plurality of audio signals output by the audio signal output unit 110, and the number of light-emitting units 120 is the same as the number of audio signals output by the audio signal output unit 110. Figures 3 and 4 are diagrams showing examples of the plurality of light-emitting units 120 corresponding to the audio output unit 110 shown in Figure 2. In the example shown in Figure 2, the audio signal output unit 110 outputs four audio signals: an audio signal LFS for the left front speaker, an audio signal RFS for the right front speaker, a left rear audio signal LRS, and a right rear audio signal RRS. 3 and 4, the plurality of light-emitting units 120 include four light-emitting units 120: a left front light-emitting unit 120LF, a right front light-emitting unit 120RF, a left rear light-emitting unit 120LR, and a right rear light-emitting unit 120RR. The left front light-emitting unit 120LF corresponds to the audio signal LFS for the left front speaker, the right front light-emitting unit 120RF corresponds to the audio signal RFS for the right front speaker, the left rear light-emitting unit 120LR corresponds to the left rear audio signal LRS, and the right rear light-emitting unit 120RR corresponds to the right rear audio signal RRS. Thus, in this embodiment, each of the plurality of light-emitting units 120 corresponds to the position of the speaker corresponding to the audio signal corresponding to that light-emitting unit 120, i.e., the direction in which the sound of the audio signal corresponding to that light-emitting unit 120 is generated.

[0025] The plurality of light-emitting units 120 may be arranged on the surface of the speaker SP, for example, as shown in Fig. 3. That is, the speaker SP may have the display device 100. The plurality of light-emitting units 120 may also be arranged on the side of the display DP, as shown in Fig. 4. That is, the display DP may have the display device 100. The plurality of light-emitting units 120 may also be part of the display area of ​​the display DP.

[0026] The control unit 130 controls the light emission of each of the plurality of light-emitting units based on the audio signal corresponding to the light-emitting unit. In the example shown in Figures 3 and 4, the control unit 130 controls the light emission of the left front light-emitting unit 120LF based on the audio signal LFS for the left front speaker corresponding to the left front light-emitting unit 120LF, controls the light emission of the right front light-emitting unit 120RF based on the audio signal RFS for the right front speaker corresponding to the right front light-emitting unit 120RF, controls the light emission of the left rear light-emitting unit 120LR based on the left rear audio signal LRS corresponding to the left rear light-emitting unit 120LR, and controls the light emission of the right rear light-emitting unit 120RR based on the right rear audio signal RRS corresponding to the right rear light-emitting unit 120RR.

[0027] As described above, in this embodiment, each of the multiple light-emitting units 120 corresponds to the position of the speaker corresponding to the audio signal corresponding to that light-emitting unit 120, that is, the direction in which the sound of the audio signal corresponding to that light-emitting unit 120 is generated. Therefore, in this embodiment, the light emitted by the light-emitting unit 120 indicates that sound is being generated in the direction in which the sound of the audio signal corresponding to that light-emitting unit 120 is being generated. Therefore, in this embodiment, the user can recognize the sound being generated in each direction based on the light emitted by the light-emitting unit 120.

[0028] <Light Emission of Light-Emitting Units 120> The control unit 130 may control the width of the light-emitting area of ​​each of the plurality of light-emitting units 120 based on the audio signal corresponding to that light-emitting unit 120. This allows the user to recognize the type of sound corresponding to that light-emitting unit 120 based on the width of the light-emitting area of ​​that light-emitting unit 120. In particular, the control unit 130 may control the width of the light-emitting area of ​​the light-emitting unit 120 based on the volume value of the audio signal corresponding to that light-emitting unit 120. For example, the control unit 130 may control the light-emitting unit 120 so that the width of the light-emitting area of ​​that light-emitting unit 120 increases as the volume value of the audio signal corresponding to that light-emitting unit 120 increases, as shown in FIG. 5 . This allows the user to recognize the volume value of the sound corresponding to that light-emitting unit 120 based on the width of the light-emitting area of ​​that light-emitting unit 120. In the example shown in Fig. 5, the illuminated area extends from left to right as the volume value increases, but the illuminated area may extend from right to left as the volume value increases, or may widen from the center to both ends as the volume value increases. In the example shown in Fig. 5, the illuminated area is rectangular, but the illuminated area may have another shape.

[0029] Furthermore, the control unit 130 may control the size of the light-emitting area of ​​each of the plurality of light-emitting units 120 based on the audio signal corresponding to that light-emitting unit 120. This allows the user to recognize the type of sound corresponding to that light-emitting unit 120 based on the size of the light-emitting area of ​​that light-emitting unit 120. In particular, the control unit 130 may control the size of the light-emitting area of ​​the light-emitting unit 120 based on the volume value of the audio signal corresponding to that light-emitting unit 120. For example, the control unit 130 may control the light-emitting unit 120 so that the light-emitting area of ​​that light-emitting unit 120 becomes larger as the volume value of the audio signal corresponding to that light-emitting unit 120 increases, as shown in FIG. 6 . This allows the user to recognize the volume value of the sound corresponding to that light-emitting unit 120 based on the size of the light-emitting area of ​​that light-emitting unit 120. In the example shown in FIG. 6 , the shape of the light-emitting area is circular, but the shape of the light-emitting area may be other shapes.

[0030] The control unit 130 may be configured to control the light emission amount (brightness) of each of the plurality of light-emitting units 120 based on the audio signal corresponding to that light-emitting unit 120. This allows the user to recognize the type of sound corresponding to that light-emitting unit 120 based on the light emission amount (brightness) of that light-emitting unit 120. The control unit 130 may be configured to control the light emission amount (brightness) of the light-emitting unit 120, for example, based on the volume value of the audio signal corresponding to that light-emitting unit 120. For example, the control unit 130 may control the light-emitting unit 120 so that the light emission amount (brightness) of that light-emitting unit 120 increases as the volume value of the audio signal corresponding to that light-emitting unit 120 increases. This allows the user to recognize the volume value of the sound corresponding to that light-emitting unit 120 based on the light emission amount (brightness) of the light-emitting unit 120.

[0031] The light-emitting patterns (light-emitting manner) and / or light-emitting colors of the multiple light-emitting units 120 may be different for each light-emitting unit 120. As described above, in this embodiment, the light emitted by a light-emitting unit 120 indicates that sound is being generated in the direction from which the sound of the audio signal corresponding to that light-emitting unit 120 is being generated. Therefore, by changing the light-emitting pattern and light-emitting color for each light-emitting unit 120, it becomes easier for the user to recognize the direction from which sound is being generated. Furthermore, the light-emitting patterns (light-emitting manner) and / or light-emitting colors of the multiple light-emitting units 120 may be different depending on the direction from which the sound of the audio signal corresponding to the light-emitting unit 120 is being generated. For example, the light-emitting patterns (light-emitting manner) and / or light-emitting colors of the multiple light-emitting units 120 may be different depending on whether the direction from which the sound of the audio signal corresponding to the light-emitting unit 120 is being generated is forward or backward.

[0032] 3 and 4 , the left front light-emitting unit 120LF and the right front light-emitting unit 120RF, which generate sound in the forward direction, have light-emitting areas that are vertically long, while the left rear light-emitting unit 120LR and the right rear light-emitting unit 120RR, which generate sound in the rearward direction, have light-emitting areas that are horizontally long. Therefore, the control unit 130 may control the left front light-emitting unit 120LF and the right front light-emitting unit 120RF so that the widths (vertical lengths) of the light-emitting areas of the left front light-emitting unit 120LF and the right front light-emitting unit 120RF increase as the volume value of the corresponding audio signal increases, and may control the left rear light-emitting unit 120LR and the right rear light-emitting unit 120RR so that the widths (horizontal lengths) of the light-emitting areas of the left rear light-emitting unit 120LR and the right rear light-emitting unit 120RR increase as the volume value of the corresponding audio signal increases. At this time, the control unit 130 may cause the width (horizontal length) of the light-emitting area of ​​the light-emitting area of ​​the left rear light-emitting unit 120LR to extend from the left side to the right side as the volume value of the corresponding audio signal increases, and may cause the width (horizontal length) of the light-emitting area of ​​the right rear light-emitting unit 120RR to extend from the right side to the left side.

[0033] Also, for example, in the example shown in Figures 3 and 4, the light color of the left front light-emitting unit 120LF and the right front light-emitting unit 120RF, which are located in the forward direction from which sound is generated, may be different from the light color of the left rear light-emitting unit 120LR and the right rear light-emitting unit 120RR.

[0034] <Arrangement of Light-Emitting Units 120> As described above, each of the multiple light-emitting units 120 corresponds to the position of the speaker corresponding to the audio signal corresponding to that light-emitting unit 120, i.e., the direction in which the sound of the audio signal corresponding to that light-emitting unit 120 is generated. Therefore, it is preferable to arrange the light-emitting units 120 so that they correspond to the direction in which the sound of the audio signal corresponding to that light-emitting unit 120 is generated, as shown in FIGS. 3 and 4 . This makes it easier for the user to recognize the direction in which the sound is generated. In the example shown in FIGS. 3 and 4 , when the left front light-emitting unit 120LF is used as a reference, the right front light-emitting unit 120RF is arranged to the right of the left front light-emitting unit 120LF, the left rear light-emitting unit 120LR is arranged below the left front light-emitting unit 120LF, and the right rear light-emitting unit 120RR is arranged below and to the right of the left front light-emitting unit 120LF.

[0035] <Gain Adjustment of Audio Signals> The multiple audio signals output from the audio signal output unit 110 may be audio signals that have undergone a predetermined gain adjustment. In this way, it is possible to emphasize a specific sound. In this case, for example, if it is desired to emphasize a soft sound, it is preferable that the multiple audio signals output from the audio signal output unit 110 be audio signals that have been converted using a C curve. Furthermore, if it is desired to emphasize a loud sound, it is preferable that the multiple audio signals output from the audio signal output unit 110 be audio signals that have been converted using an A curve.

[0036] 2, gain adjustment may be performed on the audio signals before being mixed by the mixer 112, or on the audio signals after being mixed by the mixer 112. In the example shown in Fig. 2, the audio signal output unit 110 has gain adjustment units 113, and each of the gain adjustment units 113 adjusts the gain of an audio signal for a left front speaker LFS, an audio signal for a right front speaker RFS, an audio signal for a left surround speaker LSS, an audio signal for a right surround speaker RSS, an audio signal for a left surround back speaker LSBS, and an audio signal for a right surround back speaker RSBS output from the decoder 111.

[0037] As shown in FIG. 1 , the display device 100 may further include an input unit 140 that receives input from a user. The predetermined gain adjustment may be set based on the input from the input unit 140. In this way, it becomes possible to emphasize sounds desired by the user. For example, when the user inputs via the input unit 140 that a soft sound is to be emphasized, the multiple audio signals output from the audio signal output unit 110 are audio signals converted according to a C curve (for example, in the example shown in FIG. 2 , the gain adjustment unit 113 converts the audio signal for the left front speaker LFS, the audio signal for the right front speaker RFS, the audio signal for the left surround speaker LSS, the audio signal for the right surround speaker RSS, the audio signal for the left surround back speaker LSBS, and the audio signal for the right surround back speaker RSBS according to a C curve), and the user selects a soft sound to be emphasized. When a command to emphasize a loud sound is input via the input unit 140, the plurality of audio signals output from the audio signal output unit 110 should be audio signals converted using an A-curve (for example, in the example shown in FIG. 2 , the gain adjustment unit 113 converts the audio signal for the left front speaker LFS, the audio signal for the right front speaker RFS, the audio signal for the left surround speaker LSS, the audio signal for the right surround speaker RSS, the audio signal for the left surround back speaker LSBS, and the audio signal for the right surround back speaker RSBS using an A-curve).

[0038] The present invention has been described above in terms of preferred embodiments thereof. While the present invention has been described herein with reference to specific examples, various modifications and variations can be made to these examples without departing from the spirit and scope of the present invention as set forth in the claims.
