[0033] Hereinafter, a toy according to one embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of the luminous toy 1 of this embodiment. Fig. 2 is an enlarged side view showing the inside of the main body 10 of the luminous toy 1 shown in Fig. 1. Fig. 3 is a side view showing the luminous toy 1 shown in Fig. 1 in a worn state.

[0034] The light-emitting toy 1 shown in FIG. 1 is a headphone-type toy having a pair of main bodies 10 that form earmuffs. The light-emitting toy 1 has a body-worn part 8 that is elastically deformable and serves as a curved part that corresponds to the shape of the head, and a main body 10 is provided on each end of the body-worn part 8. The light-emitting toy 1 has a light-emitting region 20 provided on the outer side surface of the main body 10. As will be described later, this light-emitting region 20 emits light in response to sound. When the light-emitting toy 1 is worn (see FIG. 3), the light-emitting regions 20 are arranged in two rows in the vertical direction (up-down direction) of the main body 10, with a first light-emitting region 21 and a second light-emitting region 22. The two rows of light-emitting regions 21, 22 are configured so that the intensity of light emission (for example, the length of light emission) changes in the row direction (up-down direction), as will be described later.

[0035] The first light-emitting region 21 and the second light-emitting region 22 are configured to change the length of light emitted in the column direction, for example, by first portions 28a, which are horizontally long (left-right direction in the figure) rectangular light-emitting portions, lined up vertically at predetermined intervals (see FIG. 7). For example, the configuration is such that light from a light-emitting portion 27 (described later) inside the main body 10 passes through the first portions 28a and is visible from the outside. Then, by increasing the number of light-emitting portions of the vertically lined first portions 28a, the length of light emitted in the vertical direction is changed.

[0036] A scale-like first figure 31 is provided on the side (adjacent position) of the first light-emitting region 21 and the second light-emitting region 22, and is aligned in the length direction (first direction (Y direction) in FIG. 8) of both light-emitting regions 21, 22 when they are emitting light. As shown in the figure, the first figure 31 is a horizontal bar-shaped scale, and is arranged so as to be located, for example, between the first portions 28a of both light-emitting regions 21, 22.

[0037] Additionally, two second shaped objects 32 having substantially the same shape as the first portion 28a are provided vertically below the first light-emitting region 21 and the second light-emitting region 22. These second shaped objects 32 do not actually emit light, but because they have the same shape as the first portion 28a, when the first portion 28a begins to emit light, the effect of light beginning to emerge upward from the upper end side of the second shaped objects 32 can be achieved.

[0038] As shown in Fig. 2, an annular earmuff ring portion 11 is provided inside the main body portion 10 so as to follow the outer edge of the inner shape of the main body portion 10. Unlike the other materials of the main body portion 10, the earmuff ring portion 11 is made of a material that provides a soft feel when in direct contact with the skin of the face when worn, as shown in Fig. 3.

[0039] The earmuff annular portion 11 does not need to be provided in advance, but can be attached as a detachable configuration according to the user's preference. Furthermore, when the device is worn on one side of the main body 10 via an extension arm 44, a microphone 45 is provided at the tip of the extension arm 44, closer to the mouth (front side) than the body-worn portion 8 in a side view, as shown in Fig. 3. The microphone 45 may also be a simulated microphone that does not actually have the function of a microphone.

[0040] The main body 10 includes, inside both sides thereof, a sound detection unit 13 consisting of a microphone, a light-emitting element 25 of the light-emitting unit 27 in the light-emitting area 20, a control unit 15 that controls the light emission of the light-emitting element 25 based on a signal from the sound detection unit 13, a memory unit 18, a power supply unit 40 with a detachable battery, and the like. As shown in FIG. 2 , a power switch 50 and a power supply unit cover 48 that allows for battery replacement are provided on the inner side of the main body 10. In this embodiment, the sound detection unit 13 is provided near the front side of the face when the light-emitting toy 1 is worn, and an opening 10h is provided on the outer surface of the main body 10 corresponding to the sound detection unit 13. In this manner, the sound detection unit 13 is positioned so that the main body 10 does not come into direct contact with the side of the face when the light-emitting toy 1 is worn on the body. This configuration allows the sound detection unit 13 to easily detect external sounds. Furthermore, the control unit 15 may be located anywhere, but in this embodiment, it is located, for example, in a position close to the power switch 50 and the light-emitting area 20.

[0041] The outer side surface of the main body 10 is provided with operational light-emitting units 41, 42, and 43 that emit light when the power switch 50 is turned on so that the operating state can be visually confirmed. The operational light-emitting units 41, 42, and 43 do not change their light-emitting intensity, but the operational light-emitting unit 41 above the first light-emitting region 21 of the light-emitting region 20 and the operational light-emitting unit 42 above the second light-emitting region 22 are aligned vertically with both light-emitting regions 21 and 22, creating a vertical (up-down) row effect for both light-emitting regions 21 and 22. The semicircular operational light-emitting unit 43 on the front side of the main body 10 illuminates the front side of the main body 10, clearly indicating that the light-emitting toy 1 is activated. The microphone 45 is also provided with two rows of operational light-emitting units 46 on its outer side surface, creating an effect of the microphone 45 being activated.

[0042] FIG. 4 is a block diagram showing a control system of the light-emitting toy 1 shown in FIG. As shown in Fig. 4, in the light-emitting toy 1, a detection signal of a sound detected by the sound detection unit 13 is transmitted to the control unit 15. The control unit 15 controls the number of lights emitted by the plurality of light-emitting units 27 in the light-emitting area 20 based on the volume of the detected sound. Here, the light-emitting area 20 is, for example, provided with two areas, a first light-emitting area 21 and a second light-emitting area 22, adjacent to each other laterally (in the front-to-back direction when worn) (see Figs. 1 and 3).

[0043] In the first light-emitting area 21, a plurality of light-emitting elements 27 that emit light based on a first group of sounds detected by the sound detection unit 13 are arranged in the vertical direction of the main body 10 in the worn state, as will be described later. The first group of sounds referred to here are set to sounds that are included in a low frequency band that is a relatively low range in the audible sound range, for example. On the other hand, in the second light-emitting area 22, a plurality of light-emitting elements 27 that emit light based on a second group of sounds detected by the sound detection unit 13 are arranged in the vertical direction similar to the first light-emitting area 21. The second light-emitting area 22 is set to emit sounds that are different in frequency from the first group of sounds, for example sounds that are included in a high-low frequency band that is a relatively high range in the audible sound range.

[0044] In this way, the first light-emitting area 21 and the second light-emitting area 22 are configured to emit light based on different frequency bands, and the light-emitting timing of both light-emitting areas 21, 22 and the number of lights emitted by light-emitting unit 27 are controlled independently by control unit 15.

[0045] Control unit 15 controls the number of light-emitting units 27 that emit light in first light-emitting region 21 and second light-emitting region 22 based on the relative loudness of sounds detected during a predetermined period via sound detection unit 13. Furthermore, for example, when control unit 15 detects a sound whose loudness is the maximum during the predetermined period, it controls all of the plurality of light-emitting units 27 to emit light, and performs light emission control corresponding to other sounds during the predetermined period using this maximum value as the maximum reference. Furthermore, when control unit 15 starts emitting light from light-emitting units 27, it controls the light emission intensity of light-emitting units 27 to increase.

[0046] Furthermore, the storage unit 18 is configured to store the maximum value detected within a predetermined period by the sound detection unit 13. For example, the sound detection unit 13 continuously detects maximum values, and the storage unit 18 stores these maximum values, but the stored data is updated to the maximum value detected during the most recent predetermined period. Therefore, light emission control is performed in a state where the maximum value stored is always the maximum value during the most recent predetermined period.

[0047] Fig. 5 is an exploded perspective view of the main part of the main body 10. Fig. 6 is an exploded perspective view showing the covering part and wall members that form the light emitting region. 5, various components are arranged in the internal space of the main body 10, which is formed by, for example, an upper half case 10a and a lower half case 10b. Openings 10c, 10d, and 10e are provided in the upper half case 10a, and cover members 41b and 43b that are transmissive to light from the light source and two covering members 28 are arranged corresponding to these openings.

[0048] The light-emitting region 20 is a collection of multiple light-emitting elements 27. The light-emitting elements 27 are formed as a light diffusion unit in a space capable of diffusing light, as shown in FIG. 6 . That is, the light-emitting elements 25 are provided within a space covered by wall members 26 covering the side and bottom surfaces and a covering member 28 covering the upper side of the wall members 26. The light-emitting elements 27 have a recessed structure with five light-emitting elements arranged in two rows. For example, partition walls 26b that partition the bottom surface 26c are arranged at predetermined intervals between front and rear (left and right in the figure) side wall surfaces 26a. Each side wall surface 26a is formed, for example, by a single circuit board that holds the light-emitting elements 25. The light-emitting elements 25 are configured to change their light-emission intensity, and the control unit 15 controls the light-emission intensity to multiple levels (e.g., three levels: strong, medium, and weak) as described below. Specifically, when light emission is initiated, light emission is initiated from a "weak" state, which is the weakest light-emission level, and then the light-emission level is changed so that the next light-emission level is a relatively stronger light-emission level. When terminating the light emission, the light emission stage is changed so that the next light emission stage is a relatively weak light emission stage, and the light emission is terminated after the "weak" light emission stage, which is the weakest light emission stage.

[0049] Here, the first light-emitting region 21 and the second light-emitting region 22, which are subjected to light emission control, each have four portions, totaling eight. That is, the operational light-emitting elements 25e installed in the two upper light-emitting sections 27 in the figure are light sources for the above-mentioned operational light-emitting sections 41 and 42, and are not subjected to blinking or light intensity control. Furthermore, the operational light-emitting section 43 on the front side of the main body 10 also has two operational light-emitting elements 25e with a similar configuration, and these operational light-emitting elements 25e may be configured to emit light in a different color from the light-emitting elements 25. Furthermore, the configuration for changing the light emission color may be such that the light emission color is changed not by the operational light-emitting elements 25e, but by a cover member covering the operational light-emitting elements 25e.

[0050] As shown in FIG. 6, the covering portion 28 is formed with 16 light-transmitting first portions 28a arranged in the longitudinal direction (vertical direction). Furthermore, the areas other than the first portions 28a are configured as second portions 28b that do not transmit light. The first portions 28a are arranged in groups of four, with levels L1, L2, L3, and L4 corresponding to the light-emitting portions 27. That is, each group of four first portions 28a is configured to be illuminated simultaneously by the light-emitting elements 25 in the light-emitting portion 27. The light-emitting elements 25 are illuminated such that the number of levels L1, L2, L3, and L4 increases from level L1 to level L4 as the sound volume increases, as will be described later.

[0051] FIG. 7 is a cross-sectional view of a portion taken along line AA in FIG. The light-emitting element 25 is provided on the side wall surface 26a of either the front or rear light-emitting portion 27 (left or right in the drawing), and irradiates light toward the front or rear into the light-emitting portion. That is, the light-emitting element 25 irradiates most of its light in a direction substantially parallel to the surface of the covering portion 28.

[0052] Furthermore, bottom surface 26c of light-emitting portion 27 is configured as a curved surface that approaches covering portion 28 as it moves away from light-emitting element 25, with bottom surface 26c facing the light-emitting element 25. This curved surface shape allows light that strikes bottom surface 26c on the side farther from light-emitting element 25 to be directed toward covering portion 28. This makes it possible to uniform the light intensity on the light-emitting element 25 side and the side farther from light-emitting element 25 when first portion 28a of covering portion 28 is viewed from the outside.

[0053] 8 to 10 are schematic side views enlarging the outer surface of the main body 10 to show changes in the light-emitting state of the first light-emitting region 21 and the second light-emitting region 22 in the light-emitting region 20. FIG. As described above, the light-emitting area 20 shown in Figures 8 to 10 shows a change in the light-emitting length of the first light-emitting column 21L and the second light-emitting column 22L, which are lined up in a row in the first direction Y (vertical direction), from one end side (lower end side 20a) to the other end side (upper end side 20b) of both light-emitting columns 21L and 22L, increasing, and conversely, a change in the light-emitting length decreasing.

[0054] 8(a) is a side view of the light-emitting area 20 showing a state in which light emission control is not being performed, and FIG. 8(b) is a side view showing the light-emitting area 20 in an initial state in which light emission of the light-emitting area 20 has started. The light-emitting toy 1 is used by wearing it on the body as shown in FIG. 3 with the power switch 50 turned on.

[0055] Before the power switch 50 is turned on, or when the sound detection unit 13 is not detecting sound, the first portion 28a is not illuminated, and no change in the light effect of the light-emitting area 20 is observed, as shown in Fig. 8(a). However, when sound is detected after the power switch 50 is turned on, for example, when both the low-pitched sound of the first light-emitting area 21 and the high-pitched sound of the second light-emitting area 22 are detected at the lower end side 20a, as shown in Fig. 8(b), both light levels L1 are illuminated. At this time, light emission starts from the weakest light emission intensity, "weak."

[0056] Thereafter, when sound is continuously detected, for example, when the device is used in an environment where music is continuously being played in the surroundings, at a certain point, as shown in FIG. 9( a), in the first light-emitting area 21, the level L1 passes through the "weak" and "medium" light-emitting stages to reach the "strong" light-emitting stage, and then the level L2 passes through the "weak" light-emitting stage to reach the "medium" light-emitting stage. In this way, after the light-emitting stage of a certain group reaches its strongest light-emitting stage, the light-emitting of the next level group begins. Meanwhile, at the same timing, in the second light-emitting area 22, the level L1 passes through the "weak" and "medium" light-emitting stages to reach the "strong" light-emitting stage.

[0057] FIG. 9(b) shows a case where the sound then increases in both the bass and treble ranges. The state shown in FIG. 9(b) represents a state in which, in the first light-emitting region 21, level L2 reaches the highest light-emitting stage, "strong," and then light emission at level L3 begins, eventually reaching the weakest light-emitting stage, "weak." As in the case shown in FIG. 9(a), control is exercised so that, after a group reaches its strongest light-emitting stage, light emission at the next level group begins. In the second light-emitting region 22, light emission at level L2 begins at the weakest light-emitting stage, "weak," and progresses to the next light-emitting stage, "medium." The first light-emitting column 21L is controlled to emit light up to level L3, while the second light-emitting column 22L is controlled to emit light up to level L2.

[0058] The state of the first light-emitting region 21 in FIG. 10(a) is a state in which the level L4 of the first light-emitting region 21 has become the "strong" light-emitting stage due to the detection of the maximum value of the low-pitched sound in a predetermined period after the state shown in FIG. 9(b). That is, as shown in FIGS. 8(a) to 10(a), the control unit 15 can control the light emission of the first light-emitting region 21 so that the light emission starts from "weak," which is the weakest light-emitting stage at the level L1 of the first light-emitting region 21, and progresses to "strong," which is the strongest light-emitting stage at the level L4 of the first light-emitting region 21. The control unit 15 can also control the light emission of the second light-emitting region 22 in a similar manner. Meanwhile, the state of the second light-emitting region 22 in FIG. 10(a) is a state in which the light emission at the level L2 has ended and the light emission at the level L1 has become weaker to "medium" due to the detection value of the high-pitched sound decreasing from the state shown in FIG. 9(b). Specifically, this is the state in which the second light-emitting area 22 goes through the weakest light-emitting stage, "weak," and then stops emitting light at level L2, then goes through the strongest light-emitting stage, "strong," at level L1, and then goes to the light-emitting stage, "medium," at level L1. In this way, when controlling to reduce the number of groups to emit light, control is performed to weaken the light-emitting stage for a certain group, and after the light-emitting stage for that group has passed the weakest light-emitting stage and stopped emitting light, control is started to weaken the light-emitting stage for the next group.

[0059] 10(b) shows a state in which the detection value of the low-pitched sound from the state in FIG. 10(a) decreases and the detection value of the high-pitched sound suddenly increases, causing the first light-emitting area 21 to change to a "weak" state at level L3 and the second light-emitting area 22 to change to a "medium" state at level L4. When light-emitting control is performed to increase the number of illuminated groups relatively significantly, as in the second light-emitting area 22 of FIGS. 10(a) and 10(b), it is preferable to control the change in light-emitting state to proceed more quickly than when light-emitting control is performed to increase the number of illuminated groups relatively slightly, as in the first light-emitting area 21 of FIGS. 9(a) and 9(b). On the other hand, when light-emitting control is performed to decrease the number of illuminated groups, as in the first light-emitting area 21 of FIGS. 10(a) to 10(b), the rate of change in light-emitting state may be constant regardless of the number of groups decreased. In addition, when no sound is detected and the light emission control for all groups is terminated, the group that continues to emit light until the end (level L1) can be controlled to continue emitting light for a certain period of time even after sound is no longer detected, thereby preventing any discomfort caused by flickering stimuli.

[0060] In this way, the lighting state of the first light-emitting area 21 and the second light-emitting area 22 is controlled independently. When a relatively loud sound is detected, the lights are emitted in an increasing manner, one group (one level) at a time, from the bottom end side 20a toward the top end side 20b, increasing the length of the lighting row. When a relatively quiet sound is detected, the length of the lighting row decreases one group (one level) at a time, from the top end side 20b toward the bottom end side 20a.

[0061] As described above, the light-emitting toy 1 of this embodiment can provide a light-emitting toy 1 that can cause the light-emitting area 20 to move in sync with the sound, for example, to produce a light-emitting effect that imitates the display of an equalizer, by controlling the number of lights emitted by the multiple light-emitting units 27 provided in the light-emitting area 20 based on the volume of the detected sound.

[0062] The light-emitting toy 1 of this embodiment is provided with the first light-emitting region 21 that emits light based on the detection of sounds of a specific frequency group (first group of sounds) and the second light-emitting region 22 that emits light based on sounds of a second group different from the first group, thereby enabling light emission based on multiple ranges of frequency groups and making the light-emitting manner (movement) of the light-emitting region 20 more complex. As a result, it is possible to create an interesting light-emitting effect in which the rhythm and tempo of the light emission are matched to, for example, music.

[0063] In this embodiment of the light-emitting toy 1, the control unit 15 controls the number of times that the light-emitting unit 27 emits light based on the relative volume of the sound detected within a specified period, thereby enabling stable light-emitting effects regardless of the environment in which the sound is generated.

[0064] In the light-emitting toy 1 of this embodiment, the latest data on the maximum sound value is constantly updated and stored by the memory unit 18, and by controlling the maximum sound during a specified period to be the maximum number of lights emitted by the light-emitting unit 27, the light-emitting state can be changed significantly even in an environment where only small sounds are detected.

[0065] Furthermore, in the light-emitting toy 1 of this embodiment, the light-emitting units 27 are capable of changing their light intensity, so that the volume change level can be expressed in more stages by changing the light intensity as well as the number of lights that are emitted. Furthermore, when the light-emitting units 27 start to emit light, the light intensity of the light-emitting units 27 is increased, and by arranging multiple light-emitting units 27 in a row, the length of the light emitted in the row changes. Furthermore, when the number of lights increases, the increasing side (the tip of the variable light) becomes brighter while the length of the row becomes longer. On the other hand, conversely, when the volume decreases, the length of the row becomes shorter while the tip of the variable light becomes darker.

[0066] Furthermore, in the light-emitting toy 1 of this embodiment, a plurality of light-emitting rows are provided for each sound frequency, so that the change in length of each light-emitting row can be enjoyed as a light effect that is similar to a change in an equalizer.

[0067] In the light-emitting toy 1 of this embodiment, the first figures 31 are arranged to form a scale in accordance with the row of light-emitting areas, which can be used as decoration to represent the change in the level of light emission. Furthermore, by arranging dummy scales of the light-emitting parts as the second figures 32 at one end of the row, the number of light-emitting parts can be made to appear visually larger.

[0068] In the light-emitting toy 1 of this embodiment, the light-emitting unit 27 is configured as a relatively large space, so that a large light-emitting area can be formed by, for example, one light-emitting element 25. Furthermore, the bottom surface 26c of the light-emitting unit 27 is configured as a curved surface that approaches the covering portion 28 as it moves away from the light-emitting element 25, so that even if the light-emitting element 25 is arranged at an uneven position in the light-emitting space, the brightness at a position far from the light-emitting element 25 can be prevented from becoming dark.

[0069] Furthermore, in the light-emitting toy 1 of this embodiment, the first part 28a, which is the transparent surface of the covering part 28, is configured to conceal the view inside, so that not only can the light-emitting structure be hidden, but the boundary between the light-emitting part and the non-light-emitting part is blurred, allowing the viewer to enjoy the large change between the non-light-emitting state and the light-emitting state.

[0070] In this embodiment of the light-emitting toy 1, the sound detection unit 13 is positioned so that when the light-emitting toy 1 is worn on the body, the main body 10 does not come into direct contact with the body, making sound detection easier and enabling accurate sound detection.

[0071] Although one embodiment of the present invention has been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, the two main bodies 10 each have a light-emitting function, but it may also be configured such that only the side on which the right microphone 45 is provided has a light-emitting function.

[0072] Furthermore, in the above embodiment, the light emission intensity of the light emitting unit 27 is controlled in three stages: strong, medium, and weak. However, this is not limited to this in the present invention, and the light emission intensity may be controlled in more stages. [Explanation of symbols]
