  FIG. 1 is a diagram illustrating an example of a functional configuration of a light emitting device 100 according to an embodiment of the present invention. The light emitting device 100 includes a multicolor light emitting element 10, an audio signal generation unit 20, a light emission color selection unit 30, a multicolor light emitting element light emission unit 40, a light emission color setting unit 50, and a light emission mode setting unit 60. . In addition, what remove | excluded the multicolor light emitting element 10 from the light-emitting device 100 corresponds to an example of the light emission control apparatus of this invention.

  The multicolor light emitting element 10 is a light emitting element that emits a plurality of colors. As the multi-color light emitting element 10, for example, a light emitting element provided with three LEDs for emitting each color of RGB is assumed, but it is not limited to this.

  The audio signal generation unit 20 takes in external audio and generates an audio signal, and includes an audio input unit 21 and an audio signal processing unit 22. The voice input unit 21 takes in external voice and converts the voice into an analog signal. A microphone is assumed as the voice input unit 21. An analog audio signal obtained by converting the audio into an analog signal is supplied to the audio signal processing unit 22.

  The audio signal processing unit 22 performs predetermined processing on the analog audio signal supplied from the audio input unit 21. As predetermined processing performed by the audio signal processing unit 22, for example, signal amplification processing for amplifying an analog audio signal supplied from the audio input unit 21, or converting the analog audio signal supplied from the audio input unit 21 into a digital audio signal A Although / D conversion processing is assumed, it is not restricted to this. Signal amplification processing is performed by the amplification unit 23, and A / D conversion processing is performed by the A / D conversion unit 24. In the following, the analog audio signal and the digital audio signal are generically referred to as an audio signal. The audio signal that has been subjected to predetermined processing in the audio signal processing unit 22 is supplied to the emission color selection unit 30.

  The light emission color selection unit 30 selects a color to be emitted from the multicolor light emitting element 10 from a plurality of colors according to the sound pressure level in the audio signal supplied from the audio signal generation unit 20. For example, the emission color selection unit 30 is assumed to be configured by the emission color sound pressure correspondence table 31, the sound pressure level detection unit 32, and the emission color collation unit 33, but is not limited thereto.

  The light emission color sound pressure correspondence table 31 associates the sound pressure level with the color to be emitted from the multicolor light emitting element 10. The sound pressure level detector 32 detects the sound pressure level in the sound signal supplied from the sound signal generator 20. The luminescent color matching unit 33 matches the sound pressure level detected by the sound pressure level detecting unit 32 with the sound pressure level detected by the sound pressure level detecting unit 32 by matching the sound pressure level detected by the sound pressure level detecting unit 32 with the luminescent color sound pressure correspondence table 31. The color to be emitted from the multicolor light emitting element 10 is selected.

  The multicolor light emitting element light emitting unit 40 causes the multicolor light emitting element 10 to emit light according to the selection in the light emission color selecting unit 30. In other words, the multicolor light emitting element light emitting unit 40 causes the multicolor light emitting element 10 to emit the color selected by the light emitting color selecting unit 30. When a light emitting element including three LEDs that emit RGB colors is used as the multicolor light emitting element 10, the multicolor light emitting element light emitting unit 40 controls light emission of the three LEDs that emit RGB colors. Accordingly, various colors can be emitted.

  The light emission color setting unit 50 sets a color to be emitted from the multicolor light emitting element 10. As a mode of setting the color to be emitted by the multicolor light emitting element 10 in the light emission color setting unit 50, for example, a mode in which which color is caused to emit light to the multicolor light emitting element 10 at which sound pressure level is assumed. Specifically, in the sound pressure level in the range of sound pressure level A to sound pressure level B, the color emitted from the multicolor light emitting element 10 is blue, and in the sound pressure level in the range of sound pressure level B to sound pressure level C. The color emitted from the multicolor light emitting element 10 is yellow, or the sound pressure level in the range of the sound pressure level A to the sound pressure level B is green, and the color emitted from the multicolor light emitting element 10 is green. At the sound pressure level in the range of level C, various colors can be set such that the color emitted from the multicolor light emitting element 10 is purple.

  In addition, the said setting aspect is an example and may be a setting aspect other than that. That is, at the sound pressure level in the range of the sound pressure level A to the sound pressure level C, the color emitted from the multicolor light emitting element 10 can be red.

  Then, the setting of the color to be emitted by the multicolor light emitting element 10 in the emission color setting unit 50 is performed by rewriting the correspondence between the sound pressure level and the color in the emission color sound pressure correspondence table 31 by the emission color setting unit 50, for example. Also good. In addition, the setting of the color to be emitted by the multicolor light emitting element 10 in the light emission color setting unit 50 associates the sound pressure level with the color to be emitted by the multicolor light emitting element 10 in advance in the light emission color sound pressure correspondence table 31, for example. A plurality of tables may be held and the light emission color setting unit 50 may select one of the plurality of tables.

  The light emission mode setting unit 60 sets the light emission mode in the multicolor light emitting element 10. As a light emission mode in the multicolor light emitting element 10, for example, a mode in which light is continuously emitted, a mode in which light is emitted by blinking, or the like is assumed, but the present invention is not limited thereto. The multicolor light emitting element light emitting unit 40 causes the multicolor light emitting element 10 to emit light in the light emitting mode set in the light emitting mode setting unit 60.

  FIG. 2 is a diagram illustrating a relationship between a sound pressure level and a color in an audio signal. FIG. 2A shows an audio signal at a certain time. For example, as shown in FIG. 2A, the sound pressure level of the audio signal is divided into seven regions. The seven areas are a sound pressure level 0 to a sound pressure level A area, a sound pressure level A to a sound pressure level B area, a sound pressure level B to a sound pressure level C area, and a sound pressure level C. A region of sound pressure level D, a region of sound pressure level D to sound pressure level E, a region of sound pressure level E to sound pressure level F, and a region of sound pressure level F to sound pressure level G.

  In FIG. 2A, the sound pressure level of the audio signal is divided into seven regions, but is not limited to this, and may be seven or more or seven or less. Further, although the width of the sound pressure level area of the audio signal is the same width in FIG. 2A, it is not limited to this, and the width of each area may be different. The width of the sound pressure level area may be variously set by the light emission color setting unit 50.

  FIG. 2B is a diagram illustrating an example of the light emission color sound pressure correspondence table 31. In the light emission color sound pressure correspondence table 31 in FIG. 2B, the color is white when the sound pressure level is from 0 to 0. This means that when the sound pressure level is in the range of sound pressure level 0 to sound pressure level A, the color emitted from the multicolor light emitting element 10 is white.

  The same applies to other cases. That is, when the sound pressure level is in the range of the sound pressure level A to the sound pressure level B in the emission color sound pressure correspondence table 31 in FIG. 2B, the color emitted from the multicolor light emitting element 10 is yellow. I mean. 2B, when the sound pressure level is in the range of the sound pressure level B to the sound pressure level C in the emission color sound pressure correspondence table 31, the color emitted from the multicolor light emitting element 10 is green. I mean. 2B, when the sound pressure level is in the range of the sound pressure level C to the sound pressure level D in the emission color sound pressure correspondence table 31 in FIG. 2B, the color emitted from the multicolor light emitting element 10 is blue. I mean. 2B, when the sound pressure level is in the range of the sound pressure level D to the sound pressure level E in the emission color sound pressure correspondence table 31 in FIG. 2B, the color emitted from the multicolor light emitting element 10 is purple. I mean. 2B, when the sound pressure level is in the range of the sound pressure level E to the sound pressure level F in the light emission color sound pressure correspondence table 31, the color emitted from the multicolor light emitting element 10 is orange. I mean. 2B, when the sound pressure level is in the range of the sound pressure level F to the sound pressure level G in the light emission color sound pressure correspondence table 31, the color emitted from the multicolor light emitting element 10 is red. I mean.

  The above correspondence between the sound pressure level and the color is an example, and the correspondence between the sound pressure level and the color may be different from the above. Further, the content of the emission color sound pressure correspondence table 31 can be changed by the emission color setting unit 50 described in FIG.
