[Figure 7] This is a cross-sectional view of the portion along line AA in Figure 3. [Figure 8] This is a schematic side view showing the emission pattern of the emission region. [Figure 9] This is a schematic side view showing the emission pattern of the emission region. [Figure 10] This is a schematic side view showing the emission pattern of the emission region. [Modes for carrying out the invention]

[0033] A toy that is one embodiment of the present invention will be described below with reference to the figures. Figure 1 is a perspective view of the light-emitting toy 1 according to this embodiment. Figure 2 is an enlarged side view showing the inside of the main body 10 of the light-emitting toy 1 shown in Figure 1. Figure 3 is a side view showing the light-emitting toy 1 shown in Figure 1 in an attached state.

[0034] The light-up toy 1 shown in Figure 1 is a headphone-type toy equipped with a pair of main body parts 10 that constitute the earcups. The light-up toy 1 has a body-mounting part 8 that is elastically deformable and curved to conform to the shape of the head, with the main body parts 10 provided at both ends of the body-mounting part 8. The light-up toy 1 has light-emitting regions 20 provided on the outer sides of the main body parts 10. These light-emitting regions 20 light up in response to sound, as will be described later. When the light-up toy 1 is worn (see Figure 3), the light-emitting regions 20 are arranged in two rows vertically (up and down) on the main body parts 10, consisting of a first light-emitting region 21 and a second light-emitting region 22. As will be described later, the magnitude of the light emission (for example, the length of the light emission) of both of these two rows of light-emitting regions 21 and 22 changes in the direction of their rows (up and down).

[0035] The first light-emitting region 21 and the second light-emitting region 22 are configured to change the length of light emission in the column direction, for example, by having rectangular luminous parts, the first portion 28a, arranged vertically at predetermined intervals (see Figure 7). For example, the light from the light-emitting part 27 inside the main body 10, which will be described later, is configured to pass through the first portion 28a and be visible from the outside. By increasing the number of these vertically arranged luminous parts of the first portion 28a, a change in the length of light emission in the vertical direction is created.

[0036] Next to the first light-emitting region 21 and the second light-emitting region 22 (at adjacent positions), there are scale-shaped first shapes 31 aligned in the longitudinal direction (first direction (Y direction) in Figure 8) when the two light-emitting regions 21 and 22 are illuminated. The first shapes 31 are horizontal bar-shaped scales as shown in the figure, and are positioned, for example, between the first portions 28a of the two light-emitting regions 21 and 22.

[0037] Furthermore, two second shapes 32, which are substantially the same shape as the first part 28a, are arranged vertically below the first light-emitting region 21 and the second light-emitting region 22. These second shapes 32 do not actually emit light, but they are the same shape as the first part 28a, and the configuration allows for the effect of the second shapes 32 emitting light upwards from their upper ends when the first part 28a starts to light up.

[0038] As shown in Figure 2, an annular ear protection portion 11 is provided on the inside of the main body portion 10, following the outer edge of the inner shape of the main body portion 10. Unlike the other materials of the main body portion 10, the ear protection portion 11 is made of a material that provides a soft feel when worn and in direct contact with the skin of the face, as shown in Figure 3.

[0039] Furthermore, the ear cushion ring portion 11 does not need to be pre-installed and can be attached or detached according to the user's preference. Also, on one side of the main body portion 10, a microphone 45 is provided at the tip of the protruding arm 44, which is positioned closer to the mouth in a side view and is located outside (forward) of the body mounting portion 8, as shown in Figure 3 when the device is worn. The microphone 45 can also be a simulated microphone that does not substantially function as a microphone.

[0040] The main body 10 is equipped with a sound detection unit 13 consisting of a microphone, a light-emitting element 25 of the light-emitting unit 27 within the light-emitting area 20, a control unit 15 that controls the illumination of the light-emitting element 25 based on the signal from the sound detection unit 13, a storage unit 18, a power supply unit 40 with a removable battery, and the like, both located inside the main body 10. As shown in Figure 2, a power switch 50 is provided on the inner side of the main body 10, and a power supply unit cover 48 for battery replacement is also provided. In this embodiment, the sound detection unit 13 is positioned towards the front of the side of the face when the light-emitting toy 1 is worn, and an opening 10h corresponding to the sound detection unit 13 is provided on the outer surface of the main body. In this way, the sound detection unit 13 is positioned so that it does not directly come into contact with the side of the face when the light-emitting toy 1 is worn on the body. This configuration makes it easy for the sound detection unit 13 to detect external sounds. Furthermore, the control unit 15 may be placed in any location, but in this embodiment, for example, it is placed in a position close to the power switch 50 and the light-emitting area 20.

[0041] Furthermore, the outer side of the main body 10 is provided with operation light-emitting sections 41, 42, and 43 that illuminate when the power switch 50 is turned on, allowing the operating status to be visually confirmed. While these operation light-emitting sections 41, 42, and 43 do not change the light intensity, the operation light-emitting section 41 above the first light-emitting area 21 and the operation light-emitting section 42 above the second light-emitting area 22 of the light-emitting area 20 are positioned vertically aligned with both light-emitting areas 21 and 22, creating a vertical (up-down) row effect for both light-emitting areas 21 and 22. Additionally, the semi-circular operation light-emitting section 43 on the front of the main body 10 brightens the front of the main body 10, clearly indicating that the light-up toy 1 is activated. The microphone 45 also has two rows of operation light-emitting sections 46 on its outer side, providing an operational effect for the microphone 45.

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

[0043] The first light-emitting region 21 consists of multiple light-emitting units 27 that emit light based on a first group of sounds detected by the sound detection unit 13, arranged vertically on the main body 10 when worn, as will be described later. The first group of sounds referred to here are set to be, for example, sounds included in the low frequency band, which is relatively in the low frequency range within the audible range. On the other hand, the second light-emitting region 22 consists of multiple light-emitting units 27 that emit light based on a second group of sounds detected by the sound detection unit 13, arranged vertically in the same way as the first light-emitting region 21. This second light-emitting region 22 is set to be sounds that have different frequencies from the first group of sounds, for example, sounds included in the high and low frequency bands, which are relatively in the high frequency range within the audible range.

[0044] Thus, the first light-emitting region 21 and the second light-emitting region 22 are configured to emit light based on different frequency bands, and the light-emitting timing of both light-emitting regions 21 and 22, as well as the number of lights emitted by the light-emitting unit 27, are controlled independently by the control unit 15.

[0045] The control unit 15 controls the number of light-emitting units 27 that emit light in the first light-emitting region 21 and the second light-emitting region 22 based on the relative magnitude of the sound detected via the sound detection unit 13 during a predetermined period. For example, when the control unit 15 detects a sound with the maximum magnitude during the predetermined period, it controls all of the multiple light-emitting units 27 to emit light, and during the predetermined period, it uses this maximum value as the maximum reference to control the emission of light corresponding to other sounds. Furthermore, when the control unit 15 starts emitting light from the light-emitting units 27, it controls the intensity of the light emitted from the light-emitting units 27 to increase.

[0046] Furthermore, the memory unit 18 is configured to store the maximum value detected by the sound detection unit 13 within a predetermined period. For example, if the sound detection unit 13 continuously detects the maximum value, the memory unit 18 stores this maximum value, but the stored data is updated to store the maximum value detected in the most recent predetermined period. Therefore, the stored maximum value is always the maximum value from the most recent predetermined period, and light emission control is performed with this value stored.

[0047] Figure 5 is an exploded perspective view of the main body 10. Figure 6 is an exploded perspective view showing the covering portion and wall members that constitute the light-emitting region. As shown in Figure 5, the main body 10 has various components arranged in an internal space formed by, for example, an upper half case 10a and a lower half case 10b. The upper half case 10a is provided with openings 10c, 10d, and 10e, and corresponding to these openings are cover members 41b, 43b that can transmit light from a light source and two covering parts 28.

[0048] The light-emitting region 20 is an aggregate of multiple light-emitting units 27. The light-emitting units 27 are formed as light-diffusing units in a space where light can be diffused, for example, as shown in Figure 6. That is, the light-emitting element 25 is provided in a space covered by a wall member 26 that covers the sides and bottom, and a covering unit 28 that covers the upper side of the wall member 26. The light-emitting units 27 are arranged in two rows of five recessed units each, and for example, partition walls 26b that demarcate the bottom surface 26c are arranged at predetermined intervals between the front and rear (left and right in the figure) side wall surfaces 26a. The side wall surfaces 26a are composed of, for example, one circuit board each that holds the light-emitting element 25. The light-emitting element 25 is configured to allow the intensity of light emission to be changed, and the control unit 15 controls the intensity of light emission in multiple stages (for example, three stages: strong, medium, and weak), as will be described later. Specifically, when starting to emit light, it starts emitting light from the weakest light emission stage, "weak," and then the control unit changes the light emission stage so that the next light emission stage is a relatively strong light emission stage. Furthermore, when terminating the light emission, the system controls the light emission stage so that the next emission stage is relatively weaker, and then terminates the emission after the "weak" state, which is the weakest emission stage.

[0049] Here, the parts constituting the first light-emitting region 21 and the second light-emitting region 22, where light emission control is performed, consist of four parts each, for a total of eight parts. That is, the operational light-emitting elements 25e installed in the two upper light-emitting sections 27 in the figure are the light sources of the aforementioned operational light-emitting sections 41 and 42, and are not subject to blinking or light intensity control. The same configuration applies to the two operational light-emitting elements 25e in the operational light-emitting section 43 on the front of the main body 10, and these operational light-emitting elements 25e may be configured to emit light in a different color than the light-emitting element 25. Furthermore, the configuration for changing the light emission color may be done not by the operational light-emitting elements 25e themselves, but by a cover member that covers the operational light-emitting elements 25e.

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

[0051] Figure 7 is a cross-sectional view of the portion along line AA in Figure 3. The light-emitting element 25 is positioned on the side wall surface 26a of either the front or rear (left or right in the figure) light-emitting section 27, and irradiates light into the light-emitting section either forward or backward. In other words, the light-emitting element 25 irradiates most of its light in a direction substantially parallel to the surface of the covering section 28.

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

[0053] Figures 8 to 10 are schematic side views of the main body 10, enlarged to show the change in the light emission state of the first light emission region 21 and the second light emission region 22 in the light emission region 20. As mentioned above, the light-emitting regions 20 shown in Figures 8 to 10 represent changes in the light emission length of both the first light-emitting rows 21L and 22L, which are arranged in a single 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), where the light emission length increases, and conversely, changes where the light emission length decreases.

[0054] Figure 8(a) is a side view of the light-emitting region 20 in a state where light emission control is not being performed, and Figure 8(b) is a side view of the light-emitting region 20 in its initial state when light emission has started. The light-emitting toy 1 is used by attaching it to the body as shown in Figure 3 with the power switch 50 turned on.

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

[0056] Subsequently, when sound is continuously detected, for example, when used in an environment where music is being played continuously in the surroundings, at a certain point, as shown in Figure 9(a), the first light-emitting region 21 shows a state where level L1 has progressed through the "weak" and "medium" light-emitting stages to reach the "strong" light-emitting stage, and then level L2 has progressed through the "weak" light-emitting stage to the "medium" light-emitting stage. In this way, the system is controlled so that the next level group begins to emit light only after the light-emitting stage of a certain group has reached its strongest light-emitting stage. Meanwhile, at the same timing, the second light-emitting region 22 shows a state where level L1 has progressed through the "weak" and "medium" light-emitting stages to reach the "strong" light-emitting stage.

[0057] Figure 9(b) shows the case where the sound increases in both the low and high frequency ranges. The state shown in Figure 9(b) represents the first light emission region 21, where after level L2 reaches the maximum light emission stage "strong", light emission at level L3 begins and then reaches the weakest light emission stage "weak". Similar to the case shown in Figure 9(a), the light emission is controlled so that after the light emission stage of a certain group reaches the strongest light emission stage, light emission of the next level group begins. In the second light emission region 22, the light emission at level L2 starts at the weakest light emission stage "weak" and progresses to the next light emission stage "medium". In the first light emission train 21L, light emission is performed for a length up to level L3, and in the second light emission train 22L, light emission is performed for a length up to level L2.

[0058] The state of the first light-emitting region 21 in Figure 10(a) is that, after the state shown in Figure 9(b), the maximum value of the sound included in the low-frequency range over a predetermined period was detected, causing the level L4 of the first light-emitting region 21 to reach the "strong" light-emitting stage. In other words, as shown in Figures 8(a) to 10(a), the control unit 15 can control the light emission in the first light-emitting region 21 so that it starts from the weakest light-emitting stage, "weak," at level L1, and progresses to the strongest light-emitting stage, "strong," at level L4. The control unit 15 can similarly control the light emission in the second light-emitting region 22. On the other hand, the state of the second light-emitting region 22 in Figure 10(a) is that, after the state shown in Figure 9(b), the detected value of the sound included in the high-frequency range has decreased, causing the light emission at level L2 to end and the light emission at level L1 to weaken to the "medium" state. Specifically, in the second light-emitting region 22, after the light emission at level L2 has ended after passing through the weakest light emission stage "weak," the state has progressed through the strongest light emission stage "strong" of level L1 to the "medium" light emission stage of level L1. In this way, when controlling to reduce the number of light-emitting groups, the control is performed to weaken the light emission stage for a certain group, and after the light emission of that group has ended after passing through the weakest light emission stage, the control to weaken the light emission stage for the next group is started.

[0059] The state in Figure 10(b) shows that, from the state in Figure 10(a), the detected values ​​of sounds in the low frequency range have decreased, and the detected values ​​of sounds in the high frequency range have suddenly increased, causing the first light-emitting region 21 to change to a "weak" state at level L3, and the second light-emitting region 22 to change to a "medium" state at level L4. When controlling the light emission to relatively change the number of light-emitting groups, as in the second light-emitting region 22 from Figure 10(a) to Figure 10(b), it is desirable to control the light emission so that the change in the light emission state progresses faster than when controlling the light emission to relatively change the number of light-emitting groups, as in the first light-emitting region 21 from Figure 9(a) to Figure 9(b). On the other hand, when controlling the light emission to decrease the number of light-emitting groups, as in the first light-emitting region 21 from Figure 10(a) to Figure 10(b), the speed of the change in the light emission state may be constant regardless of the number of groups that decrease. Furthermore, in cases where 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 suppressing physical discomfort caused by flashing stimuli.

[0060] In this way, the illumination state of the first light-emitting region 21 and the second light-emitting region 22 is controlled independently. When a relatively loud sound is detected, the lights are emitted in a manner that increases the length of the light-emitting column by one group (one level) at a time from the lower end side 20a toward the upper end side 20b. On the other hand, when a relatively quiet sound is detected, the length of the light-emitting column decreases by one group (one level) at a time from the upper end side 20b toward the lower end side 20a.

[0061] As described above, the light-emitting toy 1 of this embodiment can provide a light-emitting toy 1 that can move in conjunction with sound, for example, by controlling the number of lights emitted by the multiple light-emitting parts 27 provided in the light-emitting area 20 according to the detected sound level, thereby enabling a light-emitting effect that mimics the display of an equalizer.

[0062] In this embodiment of the light-emitting toy 1, a first light-emitting region 21 that emits light based on the detection of a specific frequency group (first group of sounds) and a second light-emitting region 22 that emits light based on a second group of sounds different from the first group are provided. This allows for illumination based on multiple ranges of frequency groups, and complicates the way the light-emitting region 20 illuminates (moves). As a result, it becomes possible to create an interesting light-emitting effect that matches, for example, a song, in rhythm and tempo.

[0063] In the light-emitting toy 1 of this embodiment, the control unit 15 controls the number of lights emitted by the light-emitting unit 27 based on the relative loudness of the sound detected within a predetermined 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 memory unit 18 constantly updates and stores the latest data of the maximum sound value, and controls the light-emitting unit 27 to emit the maximum number of lights corresponding to the loudest sound during a predetermined period, thereby enabling a significant change in the light-emitting state even in environments where only quiet sounds are detected.

[0065] Furthermore, in the light-emitting toy 1 of this embodiment, since the intensity of the light-emitting part 27 can be changed, the level of change in volume can be expressed in more stages by changing the intensity of the light in addition to changing the number of lights. Also, when the light-emitting part 27 starts to emit light, the intensity of the light emitted by the light-emitting part 27 is increased, and by arranging multiple light-emitting parts 27 in a row, the length of the light emitted in the row changes, and when the number of lights increases, the increasing side (the variable tip side) becomes brighter while the length of the row increases. On the other hand, when the volume decreases, the length of the row shortens while the variable tip side becomes darker while the light changes.

[0066] Furthermore, in the light-emitting toy 1 of this embodiment, since there are multiple light-emitting rows provided for each sound frequency, the changes in the length of each light-emitting row can be enjoyed as a light effect that simulates the changes in an equalizer.

[0067] In the light-emitting toy 1 of this embodiment, the first object 31 can be arranged to form a scale in line with the rows of light-emitting areas, thereby providing a decorative effect for changing the level of light emission. Furthermore, by arranging dummy scales for the light-emitting parts as the second object 32 on 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 section 27 is configured as a relatively large space, so that a large light-emitting area can be formed by, for example, a single light-emitting element 25. Furthermore, since the bottom surface 26c of the light-emitting section 27 is configured as a curved surface that approaches the covering section 28 as it moves away from the light-emitting element 25, even if the light-emitting element 25 is positioned unevenly within the light-emitting space, the brightness at positions far from the light-emitting element 25 will not become dimmer.

[0069] Furthermore, in the light-emitting toy 1 of this embodiment, the first portion 28a, which is the transparent surface of the covering portion 28, is configured to conceal the inside so that it cannot be seen. This not only makes the light-emitting structure invisible, but also blurs the boundary between the light-emitting and non-light-emitting parts, allowing the user to enjoy the magnitude of the change between the non-light-emitting and light-emitting states.

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

[0071] Although one aspect 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 body parts 10 are each equipped with a light-emitting function, but for example, the configuration may be such that only the side on the right side where the microphone 45 is provided is equipped with a light-emitting function.

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