Mode for Carrying Out the Invention

[0016] An embodiment of the present invention, the light-emitting device 1, is used, for example, in a concert venue, and as shown in Figures 1 and 2, comprises a housing 3, a light-emitting unit 5, an operable body (operation switch) 7, and a sound-generating body 9.

[0017] The light-emitting unit 5, the operated object 7, and the sound-generating unit 9 are all located in the housing 3. The operated object 7 moves relative to the housing 3 between a first position (see Figures 2(b) and 2(c)) and a second position different from the first position (see Figure 2(a)) when operated (for example, by a person's finger). In Figure 2, the above movement is shown as a parallel movement, but the above movement may also include rotation and changes in posture.

[0018] The operated object 7 is designed to maintain a state in the first position. That is, unless an external force of a predetermined magnitude is applied, the operated object 7 in the first position cannot move freely relative to the housing 3. Similarly, the operated object 7 is designed to maintain a state in the second position.

[0019] In the light-emitting device 1, when the operated object 7 is in the first position, the sound-generating element 9 is configured to generate a sound in accordance with the movement of the housing 3 (light-emitting device 1). Furthermore, in the light-emitting device 1, when the operated object 7 is in the second position, the sound-generating element 9 is configured to stop generating a sound even if the housing 3 (light-emitting device 1) moves.

[0020] Multiple sound-generating elements (for example, metal sound-generating elements) 9 are provided (for example, two). When the operated object 7 is in the first position, each of the multiple sound-generating elements 9 (9A, 9B) moves relative to the housing 3 (light-emitting device 1) in accordance with the movement of the housing 3 (light-emitting device 1) (including not only translation but also rotation and changes in posture). The configuration is such that the movement of the light-emitting device 1 when the housing 3 is held and shaken by hand causes the multiple sound-generating elements 9 (9A, 9B) to collide with each other and generate a sound.

[0021] For example, the sound-generating element 9 has been polished and surface-treated, resulting in a high reflectivity of visible light (over 80%).

[0022] Furthermore, when the operated object 7 is in the first position, each of the sound-generating elements 9 (9A, 9B) is configured to move relative to the housing 3 within a predetermined range. Therefore, the operated object 7 will not move indefinitely relative to the housing 3 and become separated from it.

[0023] Furthermore, when the operated object 7 is in the first position, in addition to the collision of multiple sound-generating elements 9 with each other, the sound-generating elements 9 may also generate a sound by colliding with at least one of the housing 3 or the operated object 7.

[0024] When the operated object 7 is in the second position, the multiple sound-generating elements 9 become integrated with each other, even though the housing 3 is moving, such as by being shaken. Furthermore, the multiple sound-generating elements 9 become integrated with the housing 3 and fixed to the housing 3, thereby stopping the generation of sound by the multiple sound-generating elements 9.

[0025] Furthermore, in the light-emitting device 1, a space (for example, a closed space) 11 containing multiple sound-generating elements 9 (9A, 9B) is formed between the housing 3 and the operated object 7. When the operated object 7 is in the first position, each of the multiple sound-generating elements (9A, 9B) 9 moves within the space 11 to generate a sound.

[0026] When the operated object 7 is in the second position, the volume of the space 11 is smaller than when the operated object 7 is in the first position. Also, when the operated object 7 is in the second position, multiple sound-generating elements 9 (9A, 9B) are sandwiched between the housing 3 and the operated object 7 within the space 11, for example, with a biasing force. As a result of being sandwiched, the multiple sound-generating elements 9 (9A, 9B) become integrated with each other and further integrate with the housing 3 and the operated object 7, fixing them to the housing 3. The system is configured to stop the generation of sound by the sound-generating elements 9.

[0027] Here, the light-emitting device 1 will be described in detail. The light-emitting device 1 is formed in an elongated columnar shape (for example, cylindrical). For the sake of explanation, the height direction of the column of the light-emitting device 1 will be defined as the longitudinal direction, and the direction perpendicular to the longitudinal direction will be defined as the radial direction. The housing 3 and the operated body 7 of the light-emitting device 1 are made of, for example, synthetic resin.

[0028] The housing 3 is composed of a base end portion 13 and a tip end portion 15. The base end portion 13 is formed in the shape of a bottomed cylinder, for example, from an opaque synthetic resin. The bottom plate portion 23, which constitutes the bottom of the base end portion 13, is located at the base end in the longitudinal direction. As a result, an opening is formed at the tip in the longitudinal direction of the base end portion 13. The base end portion 13 is the part that a person holds with their hand when shaking the light-emitting device 1, etc.

[0029] The tip portion 15 is formed in a free-base cylindrical shape from, for example, a transparent or translucent synthetic resin that transmits visible light. The disc-shaped base plate portion 25 that constitutes the bottom of the tip portion 15 is located on the tip side in the longitudinal direction. As a result, an opening is formed at the longitudinal base end of the tip portion 15.

[0030] The tip portion 15 is integrally installed on the base portion 13 such that its opening aligns with the opening on the base portion 13. Because the tip portion 15 is installed on the base portion 13, an internal space 17, for example, formed in a cylindrical shape, is created within the housing 3.

[0031] As shown in Figure 1, the internal space 17 houses a control unit 19, a power supply 21 such as a battery, and a light-emitting unit (for example, an LED) 5. The control unit 19 controls the light emission pattern of the light-emitting unit 5. The power supply 21 supplies power to the control unit 19 and the light-emitting unit 5. The light emitted by the light-emitting unit 5 passes through the tip end portion 15 and exits to the outside of the tip end portion 15. As a result, the surface of the tip end portion 15 emits light.

[0032] The base end portion 13 is provided with an operation switch 24 for turning the power of the light-emitting device 1 on / off, and for setting and changing the light-emitting pattern of the light-emitting section 5.

[0033] As shown in Figure 2, the operated body 7 is composed of a low-profile cylindrical base portion 29 and an elongated columnar portion (for example, a cylindrical central columnar portion) 27. The cylindrical base portion 29 is composed of a cylindrical portion 31 and a disc-shaped bottom plate portion 33 that forms the bottom. The thickness direction of the bottom plate portion 33 coincides with the longitudinal direction of the housing 3. The extension direction of the central axis of the cylindrical portion 31 and the extension direction of the central axis of the columnar portion 27 coincide with the longitudinal direction of the housing 3. The central axis of the cylindrical portion 31 and the central axis of the columnar portion 27 coincide with each other. The outer diameter of the cylindrical portion 31 coincides with the outer diameter of the front end portion 15 of the housing 3.

[0034] The cylindrical portion 31 and the columnar portion 27 protrude from one surface of the bottom plate portion 33 in the thickness direction toward the base end side (the same side as the cylindrical portion 31) in the longitudinal direction of the housing 3.

[0035] The operated object 7 is provided at the tip of the front end portion 15 of the housing 3 via the operated object support 35. The operated object support 35 is composed of a disc-shaped bottom plate portion 37, a large cylindrical portion 39, and a small cylindrical portion 41.

[0036] The thickness of the bottom plate portion 37 of the operated object support 35 coincides with the longitudinal direction of the housing 3. The central axis of the large cylindrical portion 39 and the central axis of the small cylindrical portion 41 coincide with each other. The outer diameters of the bottom plate portion 37 and the large cylindrical portion 39 coincide with the outer diameter of the front end portion 15 of the housing 3.

[0037] The large cylindrical portion 39 and the small cylindrical portion 41 protrude from one surface in the thickness direction of the bottom plate portion 37 toward the longitudinal end of the housing 3.

[0038] The outer diameter of the large cylindrical portion 39 of the operated object support 35 is slightly smaller than the inner diameter of the cylindrical portion 31 of the operated object 7.

[0039] An annular recess 43 is provided on the inner surface of the cylindrical portion 31 of the operated body 7. Multiple recesses 43 (for example, two) are provided, and the multiple recesses 43 (43A, 43B) are arranged in the longitudinal direction of the housing 3 at predetermined small intervals.

[0040] An annular protrusion 45 is provided on the outer surface of the large cylindrical portion 39 of the operated object support 35. Multiple protrusions 45 (for example, two) are provided, and the multiple protrusions 45 (45A, 45B) are arranged in the longitudinal direction of the housing 3 at predetermined small intervals, similar to the multiple recesses 43.

[0041] The recess 43 may be provided on the outer surface of the large cylindrical portion 39 of the operated body support 35, and the protrusion 45 may be provided on the inner surface of the cylindrical portion 31 of the operated body 7.

[0042] Furthermore, the operated object 7 and the operated object support 35 are made of, for example, synthetic resin, and are formed to be transparent or semi-transparent, similar to the tip portion 15 of the housing 3. The light emitted from the light-emitting unit 5 may pass through the operated object 7 and the operated object support 35 and emerge onto the operated object 7 and the operated object support 35. Alternatively, the operated object 7 and the operated object support 35 may be made of an opaque synthetic resin that does not transmit light.

[0043] The operated object support 35 is integrally installed in the housing 3 such that its bottom plate portion 37 is in surface contact with the bottom plate portion 25 of the front end portion 15 of the housing 3. Furthermore, the central axis of the front end portion 15 of the housing 3 and the central axis of the operated object support 35 coincide with each other. The front end portion 15 and the operated object support 35 may be integrally molded. In this case, the integrally molded front end portion 15 and the operated object support 35 may be referred to as the front end portion 15.

[0044] The operated object 7 is installed on the operated object support 35 such that the large cylindrical portion 39 of the operated object support 35 fits inside the cylindrical portion 31. The central axis of the operated object 7 and the central axis of the operated object support 35 coincide. The operated object 7 is also able to move to some extent in the longitudinal direction of the housing 3 relative to the operated object support 35.

[0045] As shown in Figure 2(a), the object to be operated 7 is positioned in the second position because the protrusions 45 (45A, 45B) are fitted into the recesses 43 (43A, 43B), respectively. Furthermore, as shown in Figure 2(b), the object to be operated 7 is positioned in the first position by changing the protrusions 45 that fit into the recesses 43.

[0046] When the operated object 7 is in the first position, the protrusion 45B is fitted into the recess 43A. In the first position, the amount of protrusion of the operated object 7 from the housing 3 is greater than when it is in the second position. Also, in the transitional state from the state shown in Figure 2(a) to the state shown in Figure 2(b), and in the transitional state from the state shown in Figure 2(b) to the state shown in Figure 2(a), the operated object 7 and the operated object support 35 undergo slight elastic deformation at the recess 43 and the protrusion 45.

[0047] The sound-generating element 9 is made of metal and is formed into a disc shape by press-forming a flat plate-shaped material. The sound-generating element 9 is formed in a dish shape (cymbal shape) in which the amount of protrusion (indentation) gradually increases towards the center. The outer diameter of the sound-generating element 9 is slightly smaller than the inner diameter of the cylindrical portion 31 of the operated body 7. Also, the outer diameter of the sound-generating element 9 is larger than the inner diameter of the large cylindrical portion 39 of the operated body support 35.

[0048] A circular through-hole 47 is formed in the center of the sound-generating element 9. The inner diameter of the through-hole 47 is slightly larger than the outer diameter of the columnar portion 27 of the operated object 7.

[0049] Two sound-generating elements 9 (9A, 9B) are installed within the space 11. The columnar portion 27 penetrates the through-holes 47 of the two sound-generating elements 9 (9A, 9B). The first sound-generating element 9A is installed such that its central portion protrudes towards the base end in the longitudinal direction of the housing 3. The second sound-generating element 9B is installed such that its central portion protrudes towards the front end in the longitudinal direction of the housing 3.

[0050] As shown in Figures 2(a) and 8(a), when the operated object 7 is in the second position, the sound-generating element 9 is sandwiched between the operated object support 35 and the operated object 7 in the longitudinal direction of the housing 3, so that the sound-generating element 9 is integrated with the housing 3. Therefore, no sound is generated by the sound-generating element 9.

[0051] As shown in Figures 2(b) and 2(c), when the operated object 7 is in the first position, as shown in Figure 2(c), the sound-generating element 9 moves in the longitudinal direction of the housing 3 relative to the housing 3, and by shaking the light-emitting device 1, a sound is generated by the sound-generating element 9.

[0052] By the way, in the above explanation, as shown in Figure 8(a), the operated object 7 is fixed to the operated object support 35 using the recess 43 and the protrusion 45, and the operated object 7 is moved relative to the operated object support 35. However, as shown in Figure 8(b), the operated object 7 may also be installed on the operated object support 35 by screwing the male screw 49 and the female screw 51 together. In Figure 8(c), an annular stopper 52 is provided on the operated object 7 to prevent the screw from loosening too much and causing the operated object 7 to detach from the operated object support 35. Note that in the state shown in Figures 8(b) and 8(c), the operated object 7 is in the second position.

[0053] Next, the operation of the light-emitting device 1 will be described. In the initial state, the power to the light-emitting device 1 is turned off, and the operated object 7 is in the second position.

[0054] In the initial state described above, by turning on the power of the light-emitting device 1 and specifying the light-emitting pattern for the light-emitting unit 5, the light-emitting unit 5 will emit light according to the specified light-emitting pattern.

[0055] Regardless of the light emission from the light-emitting unit 5, that is, whether the light-emitting unit 5 is emitting light or not, by positioning the operated object 7 in the first position and shaking the light-emitting device 1, a sound is generated by the sound-generating unit 9.

[0056] The light-emitting device 1 comprises a light-emitting unit 5 provided on the housing 3 and an operable body 7 also provided on the housing 3. When the operable body 7 is in a first position, the sound-generating unit 9 is configured to produce a sound in accordance with the movement of the housing 3. This allows for not only illumination but also sound generation, further enhancing the mood of audience members in concert venues and the like.

[0057] Furthermore, the light-emitting device 1 is configured such that when the operated object 7 is in the second position, the sound generation by the sound-generating element 9 is stopped. This allows the sound generation to be stopped according to the atmosphere of the concert venue, etc., and the mood of the audience members in the concert venue, etc., can be adjusted.

[0058] Furthermore, the light-emitting device 1 is equipped with multiple sound-generating elements 9, and is configured such that when the operated object 7 is in the first position, the multiple sound-generating elements 9 (9A, 9B) collide with each other to generate a sound. This allows the shape of the sound to be changed by appropriately changing the shape of the sound-generating elements 9. Moreover, by making the sound-generating elements 9 out of metal, it is possible to emit a high-pitched sound (a sound with a high number of vibrations), which can further enhance the mood of the audience in concert halls, etc.

[0059] Furthermore, in the light-emitting device 1, a space 11 containing multiple sound-generating elements 9 is formed between the housing 3 and the operated object 7. As a result, the sound-generating elements 9 do not protrude from the outside of the light-emitting device 1, giving the light-emitting device 1 a clean and uncluttered appearance.

[0060] Furthermore, in the light-emitting device 1, when the operated object 7 is in the second position, the multiple sound-generating elements 9 (9A, 9B) are sandwiched between the housing 3 and the operated object 7, thereby stopping the generation of sound. As a result, the multiple sound-generating elements 9 are firmly fixed to the housing 3 and the operated object 7, ensuring that the generation of sound is reliably stopped.

[0061] Now, with reference to Figure 3, we will describe the first modified example of the light-emitting device 1a.

[0062] The light-emitting device 1a differs from the light-emitting device 1 shown in Figure 2, etc., in that it employs a spherical sound-generating element 9a as the sound-generating element 9. Other aspects of the light-emitting device 1a are configured the same as those of the light-emitting device 1 and produce the same effect. In addition, the columnar portion 27 of the operated body 7 and the small cylindrical portion 41 of the operated support 35 are omitted in the light-emitting device 1a.

[0063] The sound-generating elements 9a are made of metal, for example, and are provided in multiples and located within the space 11. Figure 3(a) shows the state in which the operated object 7 is in the first position, and Figure 3(b) shows the state in which the operated object 7 is in the second position.

[0064] In Figure 3(a), the volume of space 11 is increased, allowing each of the multiple sound-generating elements 9a to move freely within space 11. When the light-emitting device 1 is shaken, the sound-generating elements 9a collide with each other, generating a sound.

[0065] In Figure 3(b), the volume of space 11 is reduced, and each of the multiple sound-generating elements 9a is sandwiched between the housing 3 and the operated object 7, preventing them from moving freely within space 11. Therefore, even if the light-emitting device 1a is shaken, the sound-generating elements 9a cannot move and thus do not generate sound.

[0066] In Figure 3, the diameters of the multiple sound-generating elements 9a are equal, but the diameters of each of the multiple sound-generating elements 9a may be different. Furthermore, the shape of the sound-generating elements 9a may be other shapes than spheres (for example, ellipsoidal, cylindrical, or octahedral). Also, for example, a bell with a spherical outer shape may be used as the sound-generating element 9a. In this case, when the manipulated object 7 is in the second position, a different timbre can be generated than when it is in the first position.

[0067] Next, with reference to Figure 4, we will describe the second modified example, the light-emitting device 1b.

[0068] Light-emitting device 1b differs from light-emitting device 1 shown in Figure 2, etc., in that it employs a rod-shaped sound-generating element 9b as the sound-generating element 9. Other aspects of light-emitting device 1b are configured the same as light-emitting device 1 and produce the same effect. In addition, in light-emitting device 1b, the columnar portion 27 of the operated body 7 is omitted, and a tapered (frustoconical side surface) engaging surface 53 is formed at the tip of the small cylindrical portion 41 of the operated body support 35.

[0069] The sound-generating element 9b is made of, for example, metal (it may also be made of synthetic resin), and only one is provided, and it is located within the space 11. The sound-generating element 9b is composed of a spherical sound-generating part 55, a frustoconical base 57, and an elongated rod-shaped (for example, elongated cylindrical) connecting part 59.

[0070] The sound-generating unit 55 is provided at one end of the connecting unit 59 in the longitudinal direction, and the base unit 57 is provided at the other end of the connecting unit 59 in the longitudinal direction. The central axis of the connecting unit 59 and the central axis of the base unit 57 coincide with each other, and furthermore, this central axis extends so as to pass through the center of the sound-generating unit 55. Sound is generated when the sound-generating unit 55 strikes the housing 3.

[0071] The sound-generating unit 9b is installed on the housing 3 and the operator support 35 such that the connecting portion 59 penetrates the small cylindrical portion 41 of the operator support 35, the base portion 57 is located within the space 11, and the sound-generating unit 55 is located within the front end portion 15 of the housing 3.

[0072] Figure 4(a) shows the state in which the operated object 7 is in the second position, and Figure 4(b) shows the state in which the operated object 7 is in the first position.

[0073] In the state shown in Figure 4(a), the bottom surface of the base 57 of the sound-generating element 9b is in surface contact with the bottom plate portion 33 of the operated object 7, and the frustoconical side surface of the base 57 of the sound-generating element 9b is in surface contact with the engaging surface 53 of the small cylindrical portion 41 of the operated object support 35. As a result, the sound-generating element 9b is fixed to the housing 3, etc. Even if the light-emitting device 1b is shaken, the sound-generating element 9b cannot move relative to the housing 3, etc., and therefore does not generate a sound.

[0074] In the state shown in Figure 4(b), the sound-generating element 9b is able to swing relative to the housing 3, etc. By shaking the light-emitting device 1b, the sound-generating element 9b strikes the front end portion 15 of the housing 3, generating a sound.

[0075] In the light-emitting device 1b, when the operated object 7 is in the first position, the sound-generating element 9b strikes the housing 3 and generates a sound. This allows a sound to be generated using only one sound-generating element 9b.

[0076] Next, we will describe the third modified example, the light-emitting device 1c, with reference to Figures 5 to 7.

[0077] The light-emitting device 1c differs from the light-emitting device 1 shown in Figure 2, etc., in that it employs a flat (for example, disc-shaped) sound-generating element 9c as the sound-generating element 9, and the sound-generating element 9c is provided outside the housing 3 and the operated object support 35. In other respects, the light-emitting device 1c is configured in the same way as the light-emitting device 1 and produces the same effect.

[0078] In the light-emitting device 1c, as described above, the sound-generating element 9c is provided on the outside of the housing 3. When the operated object 7 is in the first position, the sound-generating element 9c is configured to strike the housing 3 (more precisely, the operated object support 35) in accordance with the movement of the housing 3, thereby generating a sound.

[0079] Let's explain the light-emitting device 1c in more detail. The operator support 35 of the light-emitting device 1c is formed in a shape in which the openings at both ends are closed by a bottom plate portion 61 and an upper plate portion 63. A recess 65 is formed on a part of the side surface of the operator support 35, and the operator 7, which is formed in the shape of a rectangular prism, for example, is placed in this recess 65.

[0080] The operated object 7, which is installed in the recess 65, can move only in the longitudinal direction relative to the housing 3 (operated object support 35). Figures 5 to 7 show the state in which the operated object 7 is in the first position. The operated object 7 moves a predetermined distance upward (towards the longitudinal end) from the position shown in Figures 5 to 7 to reach the second position.

[0081] The flat sound-generating element 9c is, for example, formed in the shape of a disc and installed on the upper plate portion 63 of the operated object support 35. In the state shown in Figures 5 and 7, the thickness direction of the flat sound-generating element 9c and the thickness direction of the upper plate portion 63 of the operated object support 35 are in the longitudinal direction. Furthermore, the diameter of the disc-shaped sound-generating element 9c and the diameter of the upper plate portion 63 of the operated object support 35 are equal, and when the state shown in Figures 5 and 7 is viewed in the longitudinal direction, the entire upper plate portion 63 and the entire sound-generating element 9c overlap each other.

[0082] The sound-generating element 9c is supported by the operated object support 35 via a slender cylindrical support shaft 67, and is configured to rotate relative to the operated object support 35 within a predetermined range from the state shown in Figures 5 and 7 (see Figure 6).

[0083] The support shaft 67 has a central axis that extends radially, and when viewed longitudinally, it is located at the end of the circle of the sound-generating body 9c. Therefore, the support shaft 67 is located at an end of the circle of the sound-generating body 9c that is far from the center.

[0084] In the states shown in Figures 5 and 7, the bottom surface of the sound-generating element 9c is in surface contact with the upper plate portion 63 of the operated object support 35. In the state shown in Figure 6, the sound-generating element 9c rotates by a predetermined angle from the states shown in Figures 5 and 7, so that the bottom surface of the sound-generating element 9c is separated from the upper plate portion 63 of the operated object support 35.

[0085] When the operated object 7 is in the first position, the sound-generating element 9c rotates, causing it to strike the housing 3 (more precisely, the upper plate portion 63 of the operated object support 35), thereby generating a sound.

[0086] Incidentally, the operated object 7 can move upward (towards the longitudinal base end) relative to the housing 3 (operated object support 35) from the position shown in Figures 5, 6, and 7. That is, the operated object 7 can move until its contact surface 69 contacts the contact surface 71 of the sound generating element 9c. When the contact surface 69 is in contact with the contact surface 71, the operated object 7 is in the second position.

[0087] The contact surface 69 is in contact with the contact surface 71, which fixes the sound-generating element 9c to the housing 3 and the operated object support 35, preventing it from rotating. Furthermore, shaking the light-emitting element 1c does not generate any sound.

[0088] Alternatively, the sound-generating element 9c may be divided into two parts, as shown in Figure 7, and formed as a sound-generating element 9c consisting of two semicircular discs. The two semicircular discs constituting the sound-generating element 9c are designed to rotate independently of each other relative to the housing 3 and the operated object support 35.

[0089] In the light-emitting device 1c, the sound-generating element 9c is located outside the housing 3. This allows for visual recognition of the sound generation, minimizes sound attenuation, and further enhances the mood. .

[0090] Next, with reference to Figure 9, we will describe the fourth modified example of the light-emitting device 1d.

[0091] The light-emitting device 1d differs from the light-emitting device 1 shown in Figure 2, etc., in that it changes whether or not the sound-generating element 9 generates a sound using a magnet 73 provided on the operated object 7. In other respects, the light-emitting device 1d is configured the same as the light-emitting device 1 and produces the same effect.

[0092] In other words, in the light-emitting device 1d, the sound-generating element 9 is made of a magnetic material. A magnet 73 is provided on the operated object 7. When the operated object 7 is in the first position, the sound-generating element 9 generates a sound in accordance with the movement of the housing 3.

[0093] Furthermore, when the operated object 7 is in the second position, the sound generating element 9 is fixed to the housing 3 by the magnet 73, and the generation of sound by the sound generating element 9 is stopped.

[0094] Figure 9 shows the state in which the operated object 7 is in the first position. In the state shown in Figure 9, the magnetic force of the magnet 73 hardly reaches the sound generating element 9, allowing the sound generating element 9 to move relative to the housing 3.

[0095] From the state shown in Figure 9, the operated object 7 and the magnet 73 move upward by a predetermined distance, so that the operated object 7 and the magnet 73 are in a second position (not shown). With the operated object 7 and the magnet 73 in the second position, the sound generating element 9 is attracted by the magnetic force of the magnet 73 and becomes integrated with the housing 3.

[0096] In the light-emitting device 1d, when the operated object 7 is in the second position, the sound-generating element 9 is fixed to the housing 3 by the magnet 73, and the generation of sound by the sound-generating element 9 is stopped. This allows the generation of sound to be stopped with a simple configuration.

[0097] Next, with reference to Figure 10, we will describe the fifth modified example of the light-emitting device 1e.

[0098] The light-emitting device 1e differs from the light-emitting device 1d shown in Figure 9 in that the cam 75 changes whether or not the sound-generating element 9 generates a sound. In other respects, the light-emitting device 1e is configured the same as the light-emitting device 1d and produces the same effect.

[0099] In other words, in the light-emitting device 1e, the driven link 77 of the cam 75 is provided on the operated body 7, and a part of the sound-generating body 9 functions as the driven link 79 of the cam 75.

[0100] When the operated object 7 is in the first position, the sound-generating element 9 is separated from the drive mechanism 77, so that the sound-generating element 9 moves in accordance with the movement of the housing 3 and generates a sound. When the operated object 7 is in the second position, the sound-generating element 9 is fixed to the housing 3 by the drive mechanism 77, and the generation of sound by the sound-generating element 9 is stopped.

[0101] Figure 10 shows the state in which the operated object 7 is in the second position. In the state shown in Figure 10, the driving mechanism 77 is in contact with the sound generating object 9, thereby fixing the sound generating object 9 to the housing 3.

[0102] By moving the operated object 7 and the driving mechanism 77 to the left by a predetermined distance from the state shown in Figure 10, the operated object 7 and the driving mechanism 77 come to a first position (not shown). With the operated object 7 and the driving mechanism 77 in the first position, the driving mechanism 77 moves away from the sound generating element 9 (driven mechanism 79), allowing the sound generating element 9 to move relative to the housing 3.

[0103] In the light-emitting device 1e, the driven link 79 is not always restricted in its movement by the driving link 77, so strictly speaking, it cannot be said that a cam 75 is formed by the driving link 77 and the driven link 79. However, since the driving link 77 restricts the movement of the driven link 79 when the operated body 77 is in the second position, it will be included in the category of a cam in this specification. Alternatively, a link mechanism (not shown) may be used to control the generation of the sound from the sound-generating body 9.

[0104] In the light-emitting device 1e, when the operated object 7 is in the second position, the sound-generating element 9 is fixed to the housing 3 by the driving link 77 of the cam 75, and the generation of sound by the sound-generating element 9 is stopped. This allows the generation of sound to be stopped with a simple configuration.

[0105] Next, with reference to Figure 11, we will describe the sixth modified example of the light-emitting device 1f.

[0106] The light-emitting device 1f differs from the light-emitting device 1 shown in Figure 2, etc., in that it employs a spherical sound-generating element 9f as the sound-generating element 9. In other respects, the light-emitting device 1f is configured in the same way as the light-emitting device 1 and produces the same effect.

[0107] In the light-emitting device 1f, the operated object 7 is formed in a low cylindrical shape. The operated object 7 is composed of a large diameter portion 81 and a small diameter portion 83. The operated object 7 is provided at the longitudinal end of the housing 3 such that the small diameter portion 83 is located on the base end side in the longitudinal direction and the large diameter portion 81 is located on the tip side in the longitudinal direction.

[0108] The outer diameter of the large-diameter portion 81 of the operated object 7 matches the outer diameter of the housing 3, and the central axis of the operated object 7 matches the central axis of the housing 3. Furthermore, the small-diameter portion 83 of the operated object 7 is contained within a recess at the tip of the housing 3, while the large-diameter portion 81 protrudes from the tip of the housing 3. In addition, the operated object 7 can rotate relative to the housing 3 with this central axis as its center of rotation.

[0109] A string-like member 85, which has resistance only to tension, extends from the spherical sound-generating element 9f. The tip of the string-like member 85 is fixed to the outer circumference of the small-diameter portion 83.

[0110] The state shown in Figure 11 indicates that the operated object 7 is in the first position. In the state shown in Figure 11, the sound-generating element 9f can move within the housing 3. Then, by shaking the light-emitting device 1f, the sound-generating element 9f strikes the housing 3 and generates a sound.

[0111] By rotating the operated body 7 a predetermined number of times from the state shown in Figure 11, the string-like member 85 is wound up by the small-diameter section 83, causing the sound-generating element 9f to be positioned where the dashed line indicates, and the sound-generating element 9f becomes integrated with the housing 3, preventing any sound from being generated.

[0112] Next, with reference to Figure 12, we will describe the seventh modified example of the light-emitting device 1g.

[0113] The light-emitting device 1g differs from the light-emitting device 1a shown in Figure 3, etc., in that the operated object 7 is equipped with a bellows 88. In other respects, the light-emitting device 1g is configured the same as the light-emitting device 1a and produces the same effect.

[0114] The state shown in Figure 12 indicates that the operated object 7 is in the second position. In the state shown in Figure 12, the volume of space 11 is reduced, and the spherical sound-generating element 9a is integrated with the housing 3.

[0115] By moving the upper plate portion 87 of the operated body 7 upward by a predetermined distance from the state shown in Figure 12, the operated body 7 is positioned in the first position. As a result, the bellows 88 extends, increasing the volume of the space 11, and allowing the sound-generating element 9a to move relative to the housing 3.

[0116] In the light-emitting device 1g, the upper plate portion 87 is supported by a support portion (not shown). This support maintains the upper plate portion 87 in the position shown in Figure 12 (second position), and also maintains the upper plate portion 87 in a position above the position shown in Figure 12 (first position).

[0117] Next, with reference to Figure 13, we will describe the eighth modified example of the light-emitting device 1h.

[0118] The light-emitting device 1h differs from the light-emitting device 1 shown in Figure 2, etc., in that it has a retaining part 89 on the bottom plate portion 33 of the operated object 7 to prevent the operated object 7 from falling out of the housing 3. In other respects, the light-emitting device 1h is configured in the same way as the light-emitting device 1 and produces the same effect.

[0119] Figure 13 shows the state in which the operated object 7 is in the second position. From the state shown in Figure 13, the operated object 7 is moved upward relative to the housing 3, and the recess 43 is disengaged from the protrusion 45, so that the operated object 7 is in the first position.

[0120] A disc-shaped contact portion 91 is provided at the lower end of the retaining portion 89. When the operated object 7 is in the first position, the contact portion 91 contacts the upper plate portion 93 of the housing 3, thereby preventing the operated object 7 from falling out of the housing 3.

[0121] In addition, in light-emitting devices 1 to 1g, the operated object 7 in the first position cannot move relative to the housing 3, but in light-emitting device 1h, the operated object 7 in the first position can move to some extent relative to the housing 3.

[0122] Furthermore, in the light-emitting devices shown in Figures 3, 4, and 11, a sound-generating element such as a bell that generates sound on its own is used as the sound-generating element. As a result, when the operated object is in the first position, the sound-generating element generates a sound of the first tone in accordance with the movement of the housing. When the operated object is in the second position, the sound-generating element generates a sound of the second tone (a second tone different from the first tone) in accordance with the movement of the housing.

[0123] Next, we will describe the ninth modified example of the light-emitting device 1i with reference to Figures 14 and 15.

[0124] The light-emitting device 1i differs from the light-emitting device 1 shown in Figure 2, etc., in that it employs a spherical sound-generating element 9a as the sound-generating element 9. In other respects, the light-emitting device 1i is configured in the same way as the light-emitting device 1 and produces the same effect.

[0125] The light-emitting device 1i comprises a housing 3, a light-emitting part (not shown in Figure 14, etc.) provided on the housing 3, a plurality of sound-generating elements 9a, an operated element 7, and a movable element 95. The operated element 7 is provided on the housing 3 and rotates relative to the housing 3 in the direction indicated by arrow A14 when operated.

[0126] The movable body 95 is engaged with the operated object 7 and the housing 3. The movable body 95 works in cooperation with the operated object 7 and the housing 3 to form a space 97 in which multiple sound-generating elements 9a are located. The movable body 95 moves relative to the operated object 7 and the housing 3 as the operated object 7 rotates, thereby changing the volume of the space 97.

[0127] Let's explain the light-emitting device 1i in more detail. The housing 3 is provided with a male screw portion 99. The male screw portion 99 is formed, for example, from a part of the housing 3. The male screw portion 99 protrudes from the longitudinal end of the housing 3 (the part excluding the male screw portion 99). The central axis C14 of the male screw portion 99 coincides with the central axis of the housing 3 (the part excluding the male screw portion 99).

[0128] The operated object 7 is formed in a bottomed cylindrical shape, comprising a disc-shaped bottom plate portion 101 and a cylindrical side plate portion 103. A through hole 105 is formed in the center of the bottom plate portion 101. The operated object 7 is provided on the housing 3 such that the bottom plate portion 101 is in contact with the longitudinal end of the housing 3 (excluding the male screw portion 99). The central axis of the operated object 7 coincides with the central axis C14 of the male screw portion 99. The outer diameter of the operated object 7 is equal to that of the housing 3 (excluding the male screw portion 99).

[0129] The operated object 7 is mounted on the housing 3 so that it can only rotate relative to the housing 3 with the central axis C14 as the center of rotation. The male screw portion 99 passes through the through hole 105. The longitudinal end of the operated object 7 and the longitudinal end of the male screw portion 99 coincide in the longitudinal direction. A key 107 protrudes from the inner circumferential surface of the side plate portion 103 of the operated object 7. The key 107 is formed along the entire length of the side plate portion 103 (the entire length in the extension direction of the central axis C14).

[0130] The movable body 95 is formed in a disc shape. A female screw portion 109 is provided in the center of the movable body 95. The female screw portion 109 of the movable body 95 is screwed into a male screw portion 99. A keyway 111 is provided on the outer circumference of the movable body 95. A key 107 is fitted into the keyway 111. As a result, the movable body 95 moves only in the direction of extension of the central axis C14 relative to the operated object 7 (housing 3), without rotating around the central axis C14.

[0131] As described above, the structure forms a space 97 containing multiple sound-generating elements 9a between the operated body 7, the movable body 95, and the housing 3 (male screw portion 99). When the operated body 7 rotates, the movable body 95 moves in the longitudinal direction (extension direction of the central axis C14), causing the volume of the space 97 to change.

[0132] In the state shown in Figure 14(b), the volume of space 97 is at its smallest, so that, for example, multiple sound-generating elements 9a cannot move within space 97. As a result, even if the light-emitting device 1i is shaken, no sound is generated by the sound-generating elements 9a.

[0133] In the state shown in Figure 15(a), the volume of space 97 is at an intermediate value, in the state shown in Figure 15(b), the volume of space 97 is at its largest, and in the state shown in Figure 15, sound is generated by the sound-generating element 9a when the light-emitting device 1i is shaken.

[0134] In the light-emitting device 1i, the rotation of the operated object 7 causes the movable object 95 to move relative to the operated object 7 and the housing 3, changing the volume of the space 97 containing multiple sound-percussive elements 9a. By changing the volume of the space 97, the timbre of the sound produced by the collision of the multiple sound-percussive elements 9a (including a state in which no sound is produced) can be changed.

[0135] Next, the light-emitting device 1j according to the tenth modified example will be described with reference to Figures 16 and 17.

[0136] The light-emitting device 1j differs from the light-emitting device 1 shown in Figure 2, etc., in that it employs a spherical sound-generating element 9a as the sound-generating element 9. In other respects, the light-emitting device 1j is configured in the same way as the light-emitting device 1 and produces the same effect.

[0137] The light-emitting device 1j comprises a housing 3, a light-emitting part (not shown in Figure 16, etc.) provided on the housing 3, a plurality of spherical sound-generating elements 9a, an operated body 7, a housing 121 that houses the plurality of sound-generating elements 9a, and a rotating body 123.

[0138] The housing 121 and the rotating body 123 form a space 125 in which multiple spherical sound-generating elements 9a are housed. The housing 121 is composed of one rectangular flat bottom plate 127, four rectangular flat side plates 129, and one rectangular flat top plate 131. As a result, the space 125 is shaped like a rectangular parallelepiped.

[0139] The housing 121 is integrally provided with the housing 3, with its bottom plate portion 127 in contact with the housing 3. One of the four rectangular flat side plates 129, side plate portion 129A, has a smaller longitudinal dimension and is located towards the longitudinal base end. As a result, a rectangular opening 133 is formed in the housing 121.

[0140] The operated body 7 is composed of a rotating body 123 and a cylindrical operated portion 133. The rotating body 123 is formed in the shape of a rectangular flat plate. The rotating body 123 and the cylindrical operated portion 133 rotate relative to the housing 121 with a central axis C16 as the pivot point.

[0141] Then, by manually rotating the operated part 133, the rotating body 123 rotates 90°, achieving the state shown in Figure 16(b) or the state shown in Figure 17 (see arrow A16 in Figure 16 and arrow A17 in Figure 17). When the state shown in Figure 16(b) or Figure 17 is achieved, the rotating body 123 is capable of maintaining these states.

[0142] In the state shown in Figure 16(b), the volume of space 125 is increased, allowing multiple sound-generating elements 9a to move within space 125 and generate sound. In the state shown in Figure 17, the volume of space 125 is decreased, preventing multiple sound-generating elements 9a from moving within space 125 and preventing sound generation. In the state shown in Figure 17, the multiple sound-generating elements 9a may be able to move slightly.

[0143] Although this embodiment has been described above, this embodiment is not limited to these, and various modifications are possible within the scope of the gist of this embodiment. [Explanation of Symbols]
