Description

There is an application for exception to loss of novelty

The present invention relates to a speaker device such as a portable wireless speaker.

In recent years, wireless speakers have been proposed in which a lighting device is built into an omnidirectional wireless speaker that spreads out 360 degrees, creating the emotional feeling of music with a faint light, or a wireless speaker that changes the amount of light along with the music (see, for example, patent documents 1).

Conventional wireless speakers such as those described above are not intended to be used as spotlights to illuminate food on a table, or to be used while reading or working at a desk. However, by increasing the amount of light, it is conceivable that it can be used not only as a wireless speaker but also as a lighting fixture for reading.

In FIG. 1, (a) is a perspective view seen diagonally from upper left, (b) is a perspective view seen from diagonally upper right, (c) is a perspective view seen from diagonally lower left, and (d) is a perspective view seen diagonally from lower right 1 is a perspective view seen from .

FIG. 2 is a six-sided view showing an example of the illuminated speaker of the present embodiment. 2, (a) is a front view, (b) is a left side view, (c) is a right side view, (d) is a rear view, (e) is a plan view, and (f) is a bottom view.

FIG. 3 is a perspective cross-sectional view of the illuminated speaker of this embodiment. FIG. 4 is a cross-sectional view of the illuminated speaker of this embodiment. FIG. 5 is a bottom view showing an example of the mounting and demounting phases of the battery cover of the illuminated speaker of the present embodiment.

The illuminated speaker 1 of the present embodiment has a lighting unit 11, a speaker unit 12, a battery unit 13, and a rotating pedestal 14 from above, and arms 15 on the left and right. The illumination unit 11 includes a light emitting part (an LED light in this embodiment, but not limited to this) inside, and emits light downward in the state shown in FIGS. 1 and 2 .

The speaker unit 12 is a 360-degree omnidirectional speaker. The speaker unit 12 has a mesh cover 121 on the top, a speaker 125 arranged upward, a beam member 122 on the bottom, a passive radiator 126 arranged downward, and the like. A slit 123 is provided in the beam member 122 . The speaker unit 12 outputs sound through the mesh cover 121 and slits 123 . The speaker unit 12 is connected to the battery unit 13 with a beam member 122 .

The battery unit 13 has a battery, which will be described later, and supplies power to the lighting unit 11 and the speaker unit 12 . The battery unit 13 is rotatable (or rotatable) with respect to the rotating pedestal 14 with the horizontal plane (the mounting plane of the apparatus) as the direction of rotation.

The arm 15 is rotatably supported by the battery unit 13 and rotatably supports the lighting unit 11 at its tip. The battery unit 13 has a body 131 with approximately the same diameter as the body 124 of the speaker unit 12 .

As shown in FIGS. 3 and 4, the battery unit 13 has a rechargeable battery 132 and a substrate 133. As shown in FIG. A power supply circuit and the like are provided on the substrate 133 . A USB terminal 138 is provided on the rear surface of the battery unit 13 as shown in FIG. Note that the USB terminal 138 is, for example, a type C, but other types of terminals may be used. In addition, the configuration may be such that data communication with an external device via the USB terminal 138 is possible.

A bottom portion 135 of the battery unit 13 has an opening for mounting a replaceable battery 132, and a rectangular battery cover 136 is detachably attached to the opening. By removing the battery cover 136, the battery 132 can be replaced. The battery unit 13 is rotatably supported by the rotating pedestal 14 . Description will be made below with reference to FIG.

As shown in FIGS. 5A and 5B, the bottom portion 135 and the battery cover 136 horizontally rotate (or rotate) with respect to the rotating base 14 . During the rotation, the battery cover 136 is attached to the bottom 135 so as to rotate (or pivot) about the intersection of its diagonals.

In this embodiment, the size of the battery cover 136 (the length of the diagonal line 136a that is the longest part (corresponding to the diameter of rotation)) is adjusted to the bottom of the rotating pedestal 14 in order to replaceably mount a larger battery. It is configured to be larger than the diameter (140a) of the provided hole. Only at the position shown in FIG. 5A, the diameter of the hole is increased to the extent that the battery cover 136 can be attached and detached (shaped like 140b).

That is, when the rotation phase of the battery unit 13 with respect to the rotary base 14 is the phase shown in FIG. 5A or the phase rotated 180 degrees from the phase shown in FIG. Can pass through holes. On the other hand, when the rotation phase of the battery unit 13 with respect to the rotating base 14 is the phase shown in FIG. 5A or the phase rotated 180 degrees from the phase shown in FIG. The corner of the battery cover 136 is caught in the hole at the bottom of the rotating base 14 and cannot be passed through. Therefore, the battery cover 136 can be removed only in the phase of FIG. 5(a) or a phase rotated 180 degrees from FIG. 5(a). That is, the battery 132 can be replaced only in the phase of FIG. 5(a) or the phase rotated 180 degrees from FIG. 5(a).

With such a configuration, it is possible to increase the size of the battery cover 136, thereby allowing a larger battery to be replaceably mounted. That is, the illuminated speaker configured as described above is made larger by making the size of the battery cover 136 (the length of the diagonal line 136a, which is the longest part) larger than the diameter of the hole provided in the bottom of the rotary base 14. of batteries can be replaceably mounted. As a result, long-time battery drive is enabled, and usability can be improved. Further, the area of the bottom surface of the rotating base 14 can be increased, and the stability of the illuminated speaker 1 as a portable device can be improved. In addition, by preventing the battery cover 136 from coming off unless it is in a specific rotational phase, it is possible to reduce the chances of the battery cover 136 coming off due to an unexpected impact, etc., while carrying. can.

In the above configuration, the battery cover 136 has a rectangular shape and is attached at a position where the intersection (136b) of its diagonal lines (136a) corresponds to the center of rotation with respect to the rotation base 14. has a short diameter portion (140a) shorter than the diagonal length of the battery cover 136 and a long diameter portion (140b) longer than the diagonal length of the battery cover 136. When the rotary base 14 is in a specific rotational phase, the diagonal line (136a) of the battery cover 136 is positioned at the long diameter portion (140b) of the hole in the rotary base 14, and the rotary base 14 is not in the specific rotational phase. In this case, the diagonal line (136a) of the battery cover 136 is aligned with the minor diameter portion (140b) of the hole in the rotary base 14, so that when the rotary base 14 is in a specific rotational phase (Fig. 5(a) )), the battery cover 136 can be removed (that is, the battery 132 can be replaced).

However, the shape of the battery cover 136 is not limited to the rectangular shape, and may be other shapes that match the shape of the battery 132 . For example, other polygonal shapes, non-perfect circular shapes (circular shapes having a long diameter portion and a short diameter portion), and the like may be used. In that case, the hole provided in the rotating base 14 has a shape having a short diameter portion shorter than the rotation diameter of the battery cover 136 and a long diameter portion longer than the rotation diameter of the battery cover 136 . When the rotatable base 14 is in a specific rotational phase, the portion corresponding to the rotational diameter of the battery cover 136 (that is, the outermost portion with respect to the center of rotation) is positioned at the long diameter portion of the hole of the rotatable base 14. However, when the rotating base 14 is not in a specific rotational phase, the portion corresponding to the rotating diameter of the battery cover 136 is positioned at the minor diameter portion of the hole of the rotating base 14 . As a result, the battery cover 136 can be removed and the battery 132 can be replaced only when the rotating base 14 is in a specific rotational phase.

As described above, the illuminated speaker 1 of the present embodiment is a vertical wireless speaker, and has an illumination unit whose position and irradiation angle can be changed on the upper part, and is used not only as an audio but also for reading and working. It can also be used as lighting for audio equipment and lighting, and by installing a large battery, it can be used for a long time even in places where it is difficult to secure a power source, making it suitable as a desk speaker for a table. is. Although the illuminated speaker has been described as an example, the present invention can also be applied to a speaker device that does not include the lighting unit 11 (a speaker device that includes the speaker unit 12, the battery unit 13, and the rotating base 14). In general, when the light intensity of a wireless speaker with illumination is sufficient for reading or working, the power consumption becomes large, and it is necessary to install a large battery. Also, even when used as a wireless speaker, it was necessary to install a large battery in order to enable long-term use. Moreover, it is desirable that the battery to be mounted can be replaced without disassembling the device. Conventional wireless speakers were not designed for reading or working purposes, so they were not configured to be replaceable with a large, long-lasting battery for such purposes. By increasing the size of the device, it may be possible to install a large replaceable battery, but there are problems such as it being unsuitable for use as a desk speaker for a table, etc. , was solved by the present embodiment as described above. Therefore, it is possible to provide a speaker device equipped with a large battery while preventing an increase in external dimensions as a wireless speaker. In addition, it is possible to provide an illuminated speaker that can be used not only as a wireless speaker but also as a lighting fixture for reading, and that can be used for a long time regardless of the place of use.

[Second embodiment]
As described above, the illuminated speaker 1 of the present embodiment includes the speaker unit 12 (first unit) having the speaker 125 inside, the battery unit 13 (second unit) connected to the lower part of the speaker unit 12, have 3 and 4, the illuminated speaker 1 includes the passive radiator 126 inside the housing of the speaker unit 12. As shown in FIGS. The passive radiator 126 operates using air vibrations generated within the housing when the speaker 125 outputs sound, and mainly amplifies and reinforces the low frequency range. In addition, the speaker unit 12 is provided with a speaker 125 in its housing so as to output sound toward the upper part of the housing, and a passive radiator is provided inside the housing on the back side (lower part) of the speaker 125. are provided.

FIG. 6 is a perspective view of the illuminated speaker 1 viewed obliquely from below. In FIG. 6, (a) is a view viewed from the lower front, and (b) is a view viewed obliquely from the lower right. Sound output from the passive radiator 126 is output from the slit 123 .

FIG. 7 is a perspective view for explaining the internal configuration of the speaker unit 12. As shown in FIG. In FIG. 7, (a) is a diagram of the internal configuration of the speaker unit 12 as viewed obliquely from above, and (b) is a diagram of the internal configuration of the speaker unit 12 as viewed obliquely from below. The speaker 125 is supported by the speaker frame 12f. A sound absorbing material 128 is provided inside the speaker frame 12f. The sound absorbing material 128 is a member for absorbing sound inside the speaker unit 12 . The sound absorbing material 128 has, for example, the effect of absorbing medium and high-pitched sounds and standing waves to flatten the frequency characteristics and the effect of lowering the sharpness of resonance. A lower portion of the sound absorbing material 128 is supported by a resin member 129 (FIG. 8). The sound absorbing material 128 is made of an elastic material and elastically deforms. The sound absorbing material 128 is attached between the speaker 125 and the resin member 129 in a deformed state. The attached sound absorbing material 128 attempts to return to its original shape by elastic deformation, and a frictional force is generated between the speaker 125 and the contact portion with the resin member 129 . This frictional force holds the sound absorbing material 128 between the speaker 125 and the resin member 129 .

FIG. 8 is a diagram illustrating the configuration of the speaker frame 12f. In FIG. 8, (a) is a view of the speaker frame 12f viewed from directly below. (b) and (c) are perspective views of the speaker frame 12f as viewed obliquely from below. (d) is a side view of the speaker frame viewed from the direction indicated by arrow B in (a). (e) is a side view of the speaker frame viewed from the direction indicated by arrow C in (a).

A resin member 129 shown in FIG. 8 is a support member made of resin, and supports the sound absorbing material 128 from below. The resin member 129 has a shape having a step 129g, and the step 129g allows the sound absorbing material 128 to be sandwiched between the speaker 125 and the capacitor 1271 (FIG. 9) while avoiding the capacitor 1271. . The resin member 129 has a shape in which one side is largely chipped, and this chipped portion forms a sound path 120 inside the housing of the speaker unit 12 . Through this sound path 120, air vibrations (sound) from above the speaker unit 12 are transmitted to the passive radiator 126 provided below.

FIG. 9 is a diagram for explaining the configuration of the speaker substrate 127. As shown in FIG. In FIG. 9, (a) is a side view of the speaker substrate 127, and (b) is a plan view of the speaker substrate 127 viewed from above. The speaker board 127 is provided with various electronic components (not shown), a capacitor 1271, a wireless module (for example, a Bluetooth (registered trademark) module 1272), and the like. Note that the wireless module may be another wireless module such as a Wi-Fi module. The speaker substrate 127 has a shape of a semicircle or the like (a circle with a part (left side in the drawing) missing), and this missing part serves as a sound path. Air vibration (sound) from above the speaker unit 12 is transmitted to the passive radiator 126 provided below through this sound path.

10A and 10B are a front view and a sectional view of the illuminated speaker 1. FIG. In FIG. 10, (a) is a front view of the illuminated speaker 1, and (b) is a cross-sectional view of the illuminated speaker 1 taken along the cut plane AA shown in (a). As shown in FIG. 10B, a space is formed between the inner surface of the housing of the speaker unit 12 and the surroundings of the sound absorbing material 128 . That is, there is a gap around the sound absorbing material 128, and the space between the speaker 125 and the passive radiator 126 communicates linearly through the gap. This space serves as a path for sound within the speaker unit 12 .

As shown in each of the above figures, in the illuminated speaker 1, the passive radiator 126 is not located at the bottom of the illuminated speaker 1 where it is in contact with a stand such as a desk, but in the middle of the speaker unit 12 not in contact with the stand. located inside. As a result, the vibration of the sound output from the passive radiator 126 is hard to be transmitted to the stand. Furthermore, there is an upper surface 13t of the battery unit 13 at a position facing the output port (slit 123) of the passive radiator 126. As shown in FIG. The upper surface 13t is an inclined surface in which the distance from the exit of the passive radiator 126 increases toward the outside in the radial direction of the housing. The upper surface 13t and the side surface of the battery unit 13 are made of a metal such as aluminum, which has a solid structure, and can appropriately reflect the sound while suppressing the chattering sound caused by the sound output from the passive radiator 126. can. In this way, the illuminated speaker 1 can suppress deterioration in sound quality due to chattering noise or the like. The metal forming the housing of the battery unit 13 is not limited to aluminum, and other metals may be used.

With conventional wireless speakers, there was a passive radiator on the bottom of the device, so there was a problem that the vibration of the sound was transmitted to the stand and the sound quality deteriorated due to chattering, but the illuminated speaker 1 solves this problem. are doing.

Moreover, as described above, the resin member 129 has a shape having a step 129g, and is attached so that the capacitor 1271 on the speaker substrate 127 can be accommodated in the space created by the step 129g. That is, the resin member 129 supports the sound absorbing material 128 while avoiding the capacitor 1271 . With such a configuration, the size of the speaker unit 12 can be reduced (an increase in size can be suppressed).

Further, the speaker unit 12 includes a speaker 125 provided in the housing so as to output sound toward the outside of the housing (upward), and a sound absorbing material 128 on the back side (lower side) of the speaker 125. Furthermore, on the side (lower side) of the sound absorbing material 128 opposite to the speaker 125, there is a circular speaker board 127, and on the side of the speaker board 127 opposite to the sound absorbing material 128, sound is directed to the outside of the housing. and a passive radiator 126 mounted to output (downwardly).

The sound absorbing material 128 is provided so that a space (gap) is formed around it, that is, between it and the inner surface of the housing of the speaker unit 12, and this gap serves as a passage for sound. Specifically, as shown in FIG. 7, the sound absorbing member 128 has a rectangular parallelepiped shape, and a gap is formed between each side of the sound absorbing member 128 and the circular inner surface of the housing.

A Bluetooth (registered trademark) module 1272 is provided in a missing portion of the circular speaker substrate 127 (FIG. 9). The chipped portion of the circular speaker substrate 127 also serves as a passage for sound. By forming such a sound path, air vibration (sound) from the speaker 125 provided on the upper part of the speaker unit 12 is appropriately transmitted to the passive radiator 126 without increasing the size. In particular, in the present embodiment, the gap between each side of the sound absorbing material 128 and the inner surface of the housing and the missing portion of the circular speaker substrate 127 have a positional relationship in which they overlap vertically. is more easily transmitted to the passive radiator 126 side.

As described above, according to the second embodiment, it is possible to provide a compact speaker device that achieves excellent sound quality while suppressing an increase in size of the device.

[Third embodiment]
FIG. 11 is a perspective view illustrating a modification of the internal configuration of the speaker unit 12. As shown in FIG. In FIG. 11, (a) is a diagram of a modification of the internal configuration of the speaker unit 12 viewed obliquely from above, and (b) is a diagram of a modification of the internal configuration of the speaker unit 12 viewed obliquely from below. A speaker frame 12 g is arranged between the speaker 125 and the passive radiator 126 . The speaker 125 is supported by the speaker frame 12g, and the passive radiator 126 is suspended by the speaker frame 12g. A sound absorbing material 200 is attached to the speaker frame 12g. The sound absorbing material 200 is a member for absorbing sound inside the speaker unit 12 . The sound absorbing material 200 is made of an elastic material, similar to the sound absorbing material 128, and has, for example, the effect of absorbing medium and high-pitched sounds and standing waves, flattening the frequency characteristics, and reducing the sharpness of resonance. The sound absorbing material 200 is attached to the speaker frame 12g (FIG. 12) so as to block part of the semi-circular section of the substantially cylindrical space between the speaker 125 and the passive radiator 126. As shown in FIG.

FIG. 12 is a diagram illustrating the configuration of the speaker frame 12g. In FIG. 12, (a) is a top view of the speaker frame 12g. (b) and (c) are perspective views of the speaker frame 12g as viewed obliquely from above. (d) is a side view of the speaker frame viewed from the direction indicated by arrow D in (a). (e) is a side view of the speaker frame viewed from the direction indicated by arrow E in (a).

The speaker frame 12g is a frame that protrudes downward and has a substantially U shape when viewed from the side, and a substantially semicircular substrate 201 is attached thereto. The substrate 201 is arranged such that its surface is parallel to the vertical direction from the speaker 125 to the passive radiator 126 (arrow direction in FIG. 11(a)). At this time, the peripheral portion of the substrate 201 protrudes downward and substantially coincides with the bent portion of the bottom portion of the speaker frame 12g (FIG. 11(a)). Furthermore, a sound absorbing material 200 is arranged so as to sandwich the speaker frame 12g between itself and the substrate 201 (FIG. 11(b)).

Since the substrate 201 is arranged so that its surface is parallel to the vertical direction, the space between the speaker 125 and the passive radiator 126 is directly communicated to form a sound path 203 within the housing of the speaker unit 12. . Then, as described above, the sound absorbing material 200 only partially blocks the semicircular portion of the cross section of the space between the speaker 125 and the passive radiator 126 . Therefore, the cross-sectional area of the sound path 203 is larger than the cross-sectional area of the sound path of the second embodiment formed by the gap between the inner surface of the housing of the speaker unit 12 and the periphery of the sound absorbing material 128 . As a result, the air vibration (sound) from the upper part of the speaker unit 12 is efficiently transmitted to the passive radiator 126, so that the passive radiator 126 further amplifies and reinforces the bass sound of the speaker 125 more than in the second embodiment. can be done.

In addition, the substrate 201 is provided with various electronic components (not shown), a wireless module (for example, Bluetooth (registered trademark) module 202), and the like, similarly to the speaker substrate 127 . Note that the wireless module may be another wireless module such as a Wi-Fi module. In particular, the Bluetooth module 202 is arranged on the board 201 so as to face the sound absorbing material 200 , but part of it protrudes upward from the board 201 and is exposed to the sound path 203 . As described above, since the sound path 203 has a large cross-sectional area, wireless communication between the Bluetooth module 202 and a wireless communication device outside the illuminated speaker 1 can be easily performed via the sound path 203 . As a result, various operations of the illuminated speaker 1 can be reliably performed by an external wireless communication device via the Bluetooth module 202 .

[Fourth embodiment]
13 to 15 are diagrams showing how the lighting unit 11 in the speaker device (lighted speaker 1) of the present embodiment is used by changing the position and orientation of the lighting unit 11. FIG. The illuminated speaker 1 of the present embodiment includes a speaker unit 12 (first unit) having a speaker 125 inside, a lighting unit 11 provided above the speaker unit 12, and a battery unit connected to the bottom of the speaker unit 12. 13 (second unit). The illumination unit 11 includes a light emitting part (in this embodiment, an LED light (LED board 114 described later), but not limited to this), and emits light downward in the state shown in FIGS. Irradiate. In the illuminated speaker 1, a hinge 137 (FIGS. 3 and 4) is provided inside the battery unit 13 to rotatably support the arm 15. As shown in FIG. In the illuminated speaker 1, a hinge 113 (FIGS. 3 and 4) is provided inside the lighting unit 11 to rotatably support the lighting unit 11. As shown in FIG. With such a configuration, in the illuminated speaker 1, the arm 15 and the illumination unit 11 are freely rotatable. Therefore, it is possible for the user to use the illuminated speaker 1 as a lighting fixture for reading or working by illuminating any place desired by the user.

16A and 16B are a front view and a sectional view of the illuminated speaker 1. FIG. In FIG. 16, (a) is a front view of the illuminated speaker 1, and (b) is a cross-sectional view of the illuminated speaker 1 cut along the cut plane AA shown in (a). In addition, (c) is a cross-sectional view of the illuminated speaker 1 cut along the cut plane BB shown in (a), and (d) is an enlarged view of the DT1 portion of the cut plane shown in (c). It corresponds to a cross-sectional view of a portion where the arm 15 is connected. In addition, (e) is a cross-sectional view of the illuminated speaker 1 cut along the cut plane CC shown in (a), and (f) is an enlarged view of the DT2 portion of the cut plane shown in (e). This corresponds to a cross-sectional view of an upper portion of the portion where the arm 15 is connected.

As shown in FIGS. 16A and 16B, a diffuser 115 (diffusion plate) is provided below the lighting unit 11 . The diffuser 115 is made of, for example, a milky-white material that can transmit light, and is formed in a substantially conical shape (tapered shape) facing downward (that is, the direction of light irradiation by the lighting unit 11) as shown in the figure. The tapered shape has the effect of diffusing the irradiation light from the light emitting section 114 in all directions.

Also, when the diffuser 115 takes a posture in which the center of the diffuser 115 and the center of the speaker 125 face each other and are substantially aligned as shown in FIG. This has the effect of diffusing the irradiation light from the light emitting unit 114 in all directions while preventing the frontal reflection of the light from the light emitting unit 114 . Further, as shown in FIG. 14(c), the diffuser 115 may have a shape in which the taper angle changes at the boundary 115a so as to diffuse light and sound at an optimum angle. In this case, the center side from the boundary 115a may be a flat surface that does not have a diffusion effect to the extent that it does not affect sound reflection. Alternatively, a camera may be provided inside the lighting unit 11, and a lens of the camera may be provided on the center side or the like from the boundary 115a. Furthermore, a configuration in which an audio input section (not shown) having a microphone inside, etc. is provided in front of the lighting unit 11 may be employed.

Further, as shown in FIGS. 13 to 15, in the illuminated speaker 1 of the present embodiment, for example, the arm 15 rotates in a range of -25 degrees to 25 degrees (the angle in FIG. 13) with the vertical direction being 0 degrees. Possible, the lighting unit 11 can rotate from -90 degrees (the angle shown in FIG. 14) to 180 degrees (the angle shown in FIG. 15) with the state shown in FIG. It's becoming In addition, the illumination by the illumination unit 11 is dimmable, and for example, the brightness can be switched between neutral white and warm color in a plurality of steps.

It will be sandwiched between At that time, the inner diameter of the through-hole is matched with the outer diameter of the arm 15 so that a gap does not occur between the inner side of the ring of the light shielding sheet 900 and the arm 15 . 16(d) and (f) show a state in which the light shielding sheet 900 is attached to the front right arm attachment portion of the lighting unit 11. A light-shielding sheet 900 is also attached.

The light shielding sheet 900 will be described below. 17A and 17B are diagrams illustrating an example of the configuration of the light shielding sheet 900. FIG. 17, (a) is a perspective view of the light shielding sheet 900, (b) is a plan view, (c) is a side view, and (d) is a sectional view.

As shown in FIGS. 17(a) and 17(b), the light shielding sheet 900 has a ring shape, and the arm 15 is arranged inside the ring so that the arm 15 penetrates without a gap. As shown in FIG. 17C, the light shielding sheet 900 is composed of a single-sided PET sheet attached cushion material 901 and a light shielding tape 902 . PET is an abbreviation for polyethylene terephthalate.

Furthermore, as shown in FIG. 17(d), the single-sided PET sheet-attached cushion material 901 is composed of a PET film 901-1 and a polyurethane foam 901-2. The light-shielding tape 902 is composed of a black polyester film 902-1 and a black acrylic adhesive 902-2. pasted.

Since the portion where the arm 15 is attached to the lighting unit 11 is a movable portion, smooth movement is required. Further, the light shielding sheet 900 arranged at the mounting portion of the arm 15 is arranged in a state of being sandwiched between the inner surface of the housing of the illumination unit 11 and the connecting portion at the tip of the arm 15 . Therefore, by making the surface of the black polyester film 902-1 of the light shielding sheet 900 slippery to increase the slidability, smoother movement can be realized. Further, light-shielding tapes 902 with high slidability may be attached to both sides of the single-sided PET sheet-attached cushion material 901 to further enhance the slidability and light-shielding properties. That is, the light-shielding sheet 900 may have a configuration in which a cushion material 901 and a sheet (light-shielding tape 902) having higher slidability than the cushion are adhered to both sides of the cushion material 901 .

In this way, the ring-shaped light shielding sheet 900, which can be curved along the inner surface of the housing of the lighting unit 11 and into which the outer diameter of the arm 15 can be inserted without gaps, is attached to the arm 15 on the inner surface of the housing of the lighting unit 11. By mounting along the inner surface of the housing at the mounting position, it is possible to prevent the light from the lighting section inside the lighting unit 11 from leaking from the mounting portion of the arm 15 .

In addition, in the illuminated speaker 1 of the present embodiment, the arm 15 for changing the position and irradiation angle of the illumination unit 11 is connected to the battery unit 13 and the illumination unit 11, and is separated from the speaker unit 12. (the speaker unit 12 is not contacted). That is, for example, the U-shaped arm 15 has one end rotatably supported by the battery unit 13 without contacting the speaker unit 12, and the other end rotatably supports the lighting unit 11. To support. Therefore, it is possible to prevent the vibration of the speaker unit 12 from being transmitted to the lighting unit 11 via the arm 15 and causing flickering or the like. In particular, when the lighting unit 11 is equipped with a camera and a microphone, the vibration transmitted to the lighting unit 11 may affect the image quality of the image captured by the camera and the sound quality of the sound input by the microphone.
