The first light emission drive unit 21 adjusts the light emission amount and the light emission color of the first light emission unit 22 by selecting an LED that provides a drive signal (light control). In response to the first light emitting unit 22 emitting light, light is emitted from the light emitting surface 2A shown in FIGS. That is, the first light emitting unit 22 is a light emitting unit used for illumination.

The transformer circuit 23 transforms the DC voltage supplied from the power supply circuit 20 to a predetermined level. The transformed DC voltage is supplied to the illumination side microcomputer 24 and also to the switch SW1.

Further, in response to an operation input signal for instructing to turn off, the first light emission driving unit 21 is instructed to turn off all the LEDs of the first light emitting unit 22.

Further, a mounting detection unit 26 is connected to the illumination side microcomputer 24.

The attachment detection unit 26 in this example includes a mechanism unit that operates in accordance with the attachment / detachment of the electronic device 3 to / from the illumination device 2 and a switch that is turned on / off in accordance with the operation of the mechanism unit. Specifically, for example, it is composed of a mechanism portion that is pushed and pulled according to the attachment and detachment of the electronic device 3 and a switch that is turned on and off in conjunction with the pushing and pulling of the mechanism portion. The illumination-side microcomputer 24 is provided with a detection signal generated by such a mounting detection unit 26 so as to represent the attachment / detachment state of the electronic device 3.

The illumination side microcomputer 24 is connected to a data communication terminal T4 for performing data communication with a device side microcomputer 32 described later.

The wireless LAN communication unit 27 performs wireless data communication according to, for example, the IEEE 802.11 standard. The wireless LAN communication unit 27 can be connected to the Internet by establishing a connection with an external wireless LAN router.

The wireless communication unit 28 performs wireless data communication according to a wireless communication standard other than the wireless LAN. In this example, the wireless communication unit 28 performs wireless data communication based on the Bluetooth (registered trademark) standard.

Next, an internal configuration example of the electronic device 3 will be described.
The electronic device 3 includes, for example, a transformer circuit 31, a device-side microcomputer 32, a device-side function unit 33, a second light emission drive unit 34, a second light emission unit 35, a sensor unit 36, and a power supply terminal T5.

The transformer circuit 31 is configured to transform and output a DC voltage input from the power supply terminal T5 to a required voltage level of the device-side function unit 33 and the like.

The device-side microcomputer 32 includes a CPU, a ROM, and a RAM, and controls the device-side function unit 33. The device side microcomputer 32 operates by a DC voltage input from the power supply terminal T6. The device-side microcomputer 32 is connected to a data communication terminal T7 for performing data communication with the illumination-side microcomputer 24. In addition, the ROM included in the device side microcomputer 32 stores authentication information used in the authentication process. In this example, at least authentication key information is stored as authentication information.

The device-side function unit 33 comprehensively represents the configuration of each unit to be controlled by the device-side microcomputer 32. The device-side function unit 33 includes a main configuration for realizing the function as the electronic device 3. In this example, since the electronic device 3 has a sound reproduction function and an imaging function, the device-side function unit 33 has a configuration for realizing a sound reproduction function such as a speaker, an amplifier, and an acoustic signal processing unit, and an imaging function. A configuration for realizing a function of obtaining captured image data such as an optical system and an image processing unit is provided. As these configurations, known configurations can be applied in appropriate combination.

The second light emission drive unit 34 inputs the DC voltage supplied from the transformer circuit 31 as the operating voltage. Based on an instruction from the device-side microcomputer 32, a drive signal for driving to emit light from the light emitting elements constituting the second light emitting unit 35 is generated. In the case of this example, the light emitting element constituting the second light emitting unit 35 is an LED. In response to this configuration, the second light emission drive unit 34 is provided with a constant current circuit for generating a constant current at a predetermined level based on the DC voltage, and the drive signal is generated based on the output current from the constant current circuit. Generated.

As described above, the second light emitting unit 35 is composed of LEDs, specifically, eight LEDs having a peak light emission wavelength in the infrared region (850 nm (nanometer) to 950 nm in terms of wavelength). Although details will be described later, the second light emitting units 35 are arranged circumferentially at substantially equal intervals (approximately 45 degrees apart) along the outer periphery of the casing of the electronic device 3. When the second light emitting unit 35 emits light, infrared communication is performed with an electric device (for example, a television device or an air conditioner) disposed in the room, and the electric device is controlled.

The sensor unit 36 is composed of various sensors. The sensor unit 36 in this example is a generic name of, for example, a temperature / humidity sensor, an illuminance sensor, and a human sensor.

Although illustration is omitted, in this example, a portable memory such as an SD memory card or a USB (Universal Serial Bus) memory is detachable from the electronic device 3.

Here, regarding the power output terminal T2, the power output terminal T3, the data communication terminal T4, and the power supply terminal T5, the power supply terminal T6, and the data communication terminal T7 provided on the electronic device 3 side, provided on the lighting device 2 side, In each of the “power output terminal T2 and power supply terminal T5”, “power output terminal T3 and power supply terminal T6”, and “data communication terminal T4 and data communication terminal T7”, the electronic device 3 is attached to the lighting device 2. Connected accordingly. That is, according to the mounting of the electronic device 3 on the lighting device 2, it becomes possible to supply power (supply of operating voltage) from the lighting device 2 side to the electronic device 3 side, and the lighting side microcomputer 24 and the device side Data communication with the microcomputer 32 is possible.

“Example of processing executed in lighting system 1”
An example of processing executed in the lighting system 1 will be schematically described. Of course, the processing described below is an example, and processing other than that described below may be executed. In addition, the process demonstrated below is controlled by the illumination side microcomputer 24 and the apparatus side microcomputer 32, for example.

For example, an authentication process is executed between the lighting device 2 and the electronic device 3. That is, when the electronic device 3 is attached to the lighting device 2, an authentication key is transmitted from the electronic device 3 to the lighting device 2. The lighting device 2 determines whether the authentication key is a predetermined key and determines whether the electronic device 3 is a regular device. When the electronic device 3 is authenticated as a legitimate device, a sound reproduction function or the like by the electronic device 3 can be executed.

The sound playback function using the electronic device 3 is executed. For example, reproduction of music is instructed by an information processing device (not shown) realized by various computer devices such as a smartphone, a tablet terminal, and a PC (personal computer). A signal indicating this instruction is received by the wireless communication unit 28. The illumination side microcomputer 24 instructs the device side microcomputer 32 to reproduce the instructed music. The device side microcomputer 32 reproduces music according to the instruction. Note that the music data to be played back may be transmitted from the information processing device or stored in the lighting device 2 (or the electronic device 3), and is obtained via a portable memory or network. It may be a thing.

The control function for the electric device is executed using the electronic device 3. The electric device is, for example, a television device or an air conditioner in the same room as the lighting system 1. In the information processing apparatus described above, information (manufacturer, model number, etc.) relating to the electric device to be controlled is registered. From the information processing apparatus, for example, a control command for turning on / off a registered air conditioner is received by the wireless communication unit 28. The illumination side microcomputer 24 supplies a control command from the information processing apparatus to the device side microcomputer 32 via the data communication terminal T4.

The device-side microcomputer 32 executes the modulation process by driving the second light emission drive unit 34 so that the control command is adapted to the air conditioning device to be controlled. When the second light emission drive unit 34 is driven, the second light emission unit 35 emits light, and a control command by infrared light communication is emitted as an optical signal (infrared light). This control command is received by the air conditioner that is the control target, and the air conditioner is turned on / off. Note that a control command from the information processing apparatus may be supplied to the lighting apparatus 2 via the Internet, thereby enabling various devices to be controlled from outside (outdoors).

"Example configuration of electronic equipment"
By the way, when the electronic device 3 having the sound reproduction function and the imaging function is attached to the lighting device 2 as in the lighting system 1, it is necessary to pay attention to the following points. First, it is desired to prevent the vibration of the speaker from propagating to the ceiling surface when the electronic device 3 reproduces sound. This is because, for example, in the case of an apartment house, there is a possibility of causing discomfort to residents living on the upper floor due to vibrations propagated to the ceiling surface. Secondly, it is desired to prevent the vibration of the speaker from propagating to the lighting device 2. This is because the vibration of the speaker propagates to the illuminating device 2 so that the illumination light may shake and flicker. Thirdly, when the electronic device 3 has an imaging function, the camera image may be blurred due to the vibration of the speaker. Therefore, the configuration of the electronic device 3 corresponding to these points is desired without increasing the cost by increasing the number of speakers or enlarging the entire unit. Hereinafter, the electronic device 3 according to an embodiment of the present technology made in view of these points will be described in detail.

A physical configuration example of the electronic device 3 will be described with reference to FIGS. 4 is a cross-sectional view of the electronic apparatus 3 according to an embodiment, FIG. 4A is a perspective view for explaining a configuration example of the electronic apparatus 3 according to the embodiment, and FIG. It is a perspective view (partially exploded perspective view) for demonstrating the structural example of the electronic device 3 which concerns on a form. 4A and 4B, the electronic device 3 is shown upside down.

The electronic device 3 has a substantially cylindrical shape as a whole, and has a casing 300 that is slightly wider toward one end side (floor side). The casing 300 has a substantially ring-shaped upper casing portion 300A whose one end is sealed with an upper surface, a base casing portion 300B that is substantially ring-shaped and wide on the floor side, and a substantially ring-shaped lower casing portion. 300C. The upper housing portion 300A, the base housing portion 300B, and the lower housing portion 300C are engaged and fixed by screws or the like, so that the housing 300 is configured.

The upper housing part 300A and the base housing part 300B are made of resin or the like. Further, the lower housing part 300C is made of a member that transmits infrared light, and its outer edge functions as a light guide component 340 described later. The light guide component 340 is a member that is arranged in the emission direction of the infrared light emitted from the second light emitting unit 35 and diffuses a part of the infrared light in a predetermined direction. A functional unit 3A described later is housed in an internal space formed in the housing 300.

A flat portion 301 is formed from the light guide component 340 of the lower housing portion 300 </ b> C toward the inside of the housing 300. For example, a second light emission drive unit 34, a second light emission unit 35, and a sensor unit 36 are disposed on the flat portion 301 (note that only a part of them is given a reference numeral in the figure).

Release levers 302 </ b> A and 302 </ b> B are disposed on the outer surface of the housing 300. When the electronic device 3 is removed from the lighting device 2, the user performs an operation of removing the two

release levers

302A and 302B while pressing the two

release levers

302A and 302B. That is, the electronic device 3 cannot be detached from the lighting device 2 unless the electronic device 3 is grasped with both hands. Thereby, the electronic device 3 can be prevented from dropping when the electronic device 3 is attached or detached.

A plurality of terminals for pulling (an example of an attachment portion) are exposed from the upper surface of the upper housing portion 300A. These terminals are fixed by screws or the like in the upper housing portion 300A, and these terminals are attached to the mounting portion 2B of the lighting device 2 so that the electronic device 3 is supported by the lighting device 2. It is made up. From the upper surface of the upper housing part 300A, for example, three L-shaped metal terminals are exposed on the circumference. Among these, two terminals are a power supply terminal T5 and a power supply terminal T6, and the other one is a towing terminal T8. Note that illustration of the data communication terminal T7 is omitted.

Further, erroneous insertion prevention guides 303A and 303B for preventing the electronic device 3 from being attached to the mounting portion 2B in the wrong direction or the like, and the electronic device 3 fall from the lighting device 2 to the upper housing portion 300A. Lock pins 304A and 304B are provided to prevent the In addition, the arrangement | positioning location and number of these guides and pins can be changed suitably.

As shown in FIG. 4B, a substantially circular speaker net (net grill) NE is attached to the lower housing part 300C along the vicinity of the outer edge thereof.

"Example of functional unit configuration"
Next, a configuration example of the functional unit 3A will be described with reference to FIGS. 6 and 7 in addition to FIGS. 6A is a perspective view illustrating an example of the appearance of the functional unit 3A, FIG. 6B is a partial perspective view of the functional unit 3A, and FIG. 7 is a top view for explaining a configuration example of the functional unit 3A. It is.

The functional unit 3A includes a substantially circular substrate 320, and the functional unit 3A is housed and supported in the housing 300 so that the substrate 320 is on the lower side. Although detailed description and illustration are omitted as appropriate, each component of the electronic device 3 described in FIG. 3 is connected to the substrate 320 with an appropriate circuit configuration.

The substrate 320 is formed with a through-hole for attaching the speaker unit SP and a through-hole 321 (see FIG. 6) as a camera attachment part to be attached to the imaging device (referred to as a camera as appropriate). Each figure shows a state in which the speaker unit SP is attached. A lens barrel 325 of the camera is attached to the through hole 321 so as to close the through hole 321. An imaging unit 326 of the camera is exposed below the substrate 320. As a result, the room can be photographed using the camera.

The speaker unit SP is disposed offset from the center of the substrate 320, and the bass reflex duct 332 is disposed so as to intersect substantially between the center of the substrate 320 and the speaker unit SP. Note that measures against air leakage are taken at a joint portion between the speaker box 330 and the substrate 320 via a gasket or the like.

The speaker unit SP is, for example, a full range speaker. A speaker box 330 as an enclosure (sound reproduction space) is formed on the upper surface of the substrate 320. In this example, a bass reflex system is used as an enclosure system to supplement the low frequency characteristics, and a port 331 is formed on the bottom side of the functional unit 3A. A bass reflex duct 332 is connected to the port 331.

The port shape at both ends of the bass reflex duct 332 is, for example, a flare shape in which the cross-sectional area gradually increases toward at least the outlet side (port 311 side) toward the outlet. The inlet side of the bass reflex duct 332 may also have a flare shape. The bass reflex duct 332 emits an acoustic vibration having a phase opposite to that of the speaker unit diaphragm to the atmosphere, but the pulsation amplitude of the air near the outlet of the port 331 corresponds to the sound pressure level of the speaker. The air pulsation also affects the speaker net NE provided on the outlet side of the speaker unit SP. By reducing the port shape to a flare shape, an effect of reducing intake pulsation from the port 331 can be obtained.

Subsequently, an example of the shape of the speaker box 330 will be described. When the standing wave generated in the speaker box 330 matches the frequency of the reproduced sound, the reproduction characteristics of the speaker unit SP are affected. In this example, the cross-sectional shape of the speaker box 330 in the horizontal direction is a shape that can suppress and prevent the occurrence of standing waves. Examples of shapes that can suppress and prevent the occurrence of standing waves include shapes that do not have surfaces parallel to each other. In this example, the horizontal cross-sectional shape of the speaker box 330 is based on a substantially circular shape, and a deformed portion 330A in which a part of the circular shape is deformed inward, and a curved protrusion 330B formed by the deformation, A deformed circular shape having 330C is used. With this shape, the generation of standing waves can be suppressed and prevented. As a general measure against standing waves, a sound absorbing material effective in a specific frequency band is often placed in the speaker box 330. However, in this example, the sound absorbing material can be made unnecessary.

In addition, by making the cross-sectional shape of the speaker box 330 into a deformed circular shape, a space for forming the through-hole 321 at a position spaced apart from the speaker box 330 on the substrate 320, in other words, at a position adjacent to the substrate 320 with a slight gap. Can be obtained. The electronic device 3 is assumed to be portable and attached to the ceiling as one of the usage forms. For this reason, it is not preferable to increase the size of the electronic device 3, and the size of the substrate 320 is necessarily limited. Considering this point, if the cross-sectional shape of the speaker box 330 is a deformed circular shape, the through hole 321 can be formed, and the space of the substrate 320 can be effectively utilized.

The vibration of the speaker unit SP propagates to the surroundings by the air pulsation generated from the diaphragm of the speaker unit SP and the bass reflex duct 332 as a vibration source. In this example, the speaker box 330 is arranged in the housing 300 of the electronic device 3 to form a double structure. Thereby, it is possible to suppress the propagation of vibrations to the outside, that is, the outside of the housing 300, and it is possible to prevent the vibrations from propagating to the ceiling. It is also conceivable that the casing 300 itself of the electronic device 3 is a speaker box. However, in this configuration, the housing 300 needs to be securely sealed, and the cost may increase due to the configuration. Moreover, in order to suppress vibration, it is necessary to increase the rigidity of the housing 300, and the weight increases accordingly. Therefore, although it becomes unsuitable as an apparatus which can be carried and is attached to a ceiling side, these problems do not arise with the structure of the electronic device 3 mentioned above.

Also, by making the port shape of the bass reflex duct 332 a flare shape, air pulsation in the low frequency component is reduced, contributing to the reduction of vibration. Thereby, propagation of vibration to the ceiling or the like can be effectively suppressed.

In general, when a stationary speaker box is placed on the floor, it is known that the floor box and the floor of the speaker box are supported at three points so as to have a vibration blocking effect on the floor. . Considering this point, also in this example, the electronic device 3 having the speaker unit SP is supported at three points. For this reason, the effect which further interrupts | blocks propagation of the vibration to a ceiling is acquired.

The vibration reduction effect due to the above-mentioned speaker reproduction can prevent propagation of vibration to the camera body. Furthermore, since an air layer is interposed between the speaker box 330 and the camera, vibration propagation can be more effectively prevented. Therefore, it is possible to realize an integrated configuration of the speaker unit SP and the camera while preventing blurring of the captured image of the camera.

In addition, as shown in FIG. 4, the step part 328 may be provided in the board | substrate 320, and the speaker unit SP and the through-hole 321 may be formed on a different plane. Thereby, it is possible to prevent the vibration of the speaker unit SP from directly propagating to the camera attached to the through hole 321.

“Example of the arrangement of the second light emitter”
Next, an arrangement example of the second light emitting unit 35 that is a control command sending unit will be described. Usually, there is a remote control device that is supposed to be placed on a table, but there are many cases where there are shielding objects between the remote control device and the control target device depending on the surrounding environment, and there are many restrictions on the installation location. For example, if an omnidirectional cover is assumed, floor placement will be ideal, but it will interfere with daily life, so it will inevitably be placed on a desk or the like. In this case, if the light receiving unit is on the floor side of the installation location, the performance as a remote control device may be impaired.

In this example, the second light emitting unit 35 is arranged on the electronic device 3, that is, on the ceiling side. Thereby, the influence by a shield can be reduced. Even in this case, it is necessary to pay attention to the following points. First, it is necessary to emit infrared light in all directions, and it is necessary that the infrared light does not interfere with illumination. The second emitted infrared light needs to be emitted in the horizontal direction and the floor surface direction. This is because there are devices to be controlled on the ceiling, such as an air conditioner, or on the wall surface in the vicinity thereof, and there are devices installed on the floor, such as a television device. An arrangement example of the second light emitting unit 35 in consideration of the above points will be described.

FIG. 8 is a diagram for explaining an arrangement example of the second light emitting unit 35, and is an enlarged view of a predetermined portion of the electronic device 3. Note that, in determining the transmission range of the second light emitting unit 35, which is generally an infrared LED, the half-value angle of the emission radiation intensity (50% emission intensity range) is used as a design standard.

The second light emitting unit 35 is attached to the flat portion 301 by an appropriate attachment member, for example. As described above, the outer edge of the lower housing portion 300C functions as the light guide component 340. A part of the infrared light emitted from the second light emitting unit 35 is emitted through the light guide component 340.

An example of the light guide component 340 will be described. The light guide component 340 has a thickness of about 1 to 2 mm, for example, and has a plate-like cross section. The light guide component 340 is made of a material having a high infrared light transmittance, such as polycarbonate (PC) or acrylic (PMMA). The surface state of the light guide component 340 has smoothness of the incident surface in order to increase the effectiveness of the reflection component. In addition, by including a material having a predetermined diffusibility (a diffusing agent that diffuses light) in the light guide component 340, the radiation intensity characteristics associated with the disposition of the discrete second light-emitting portions 35 can be leveled and diffused. The effective range is expanded. As an example, it is preferable to use a PC resin translucent diffusing material having optical transmittance of 70% and diffusibility (a diffusion angle of about 30 deg from the exit surface) as optical characteristics.

FIG. 9 is a cross-sectional view of a portion that functions as the light guide component 340 in the lower housing portion 300C. As illustrated in FIG. 9, the light guide component 340 includes an upper surface 341, a bottom surface 342, and an inner surface 343 and an outer surface 344 that connect the upper surface 341 and the bottom surface 342. The inner surface 343 has a configuration in which a first inner surface 343A and a second inner surface 343B are continuously formed. The first inner surface 343A is a surface on which infrared rays emitted from the second light emitting unit 35 are incident at a critical angle or less. The boundary between the first inner surface 343A and the second inner surface 343B is the boundary portion 345, and the infrared light transmitted through this portion becomes the limit of the transmission component.

The second inner surface 343B and the outer surface 344 are formed to be substantially parallel. Thereby, the light guide component of the infrared light mentioned later can be obtained. Further, rounded R-shaped

portions

346A and 346B are formed on at least one of the boundary between the bottom surface 342 and the inner surface 343 and the boundary between the bottom surface 342 and the outer surface 344.

Again, referring back to FIG. The second light emitting unit 35 is disposed at a substantially equal angle on the horizontal radiation axis with the vertical (height) direction as the central axis (Z axis) with respect to the floor surface. For example, when an infrared LED having a half-value angle θ1 / 2 of ± 27 deg (full angle 52 deg) is used as the second light emitting unit 35, the horizontal direction is theoretically horizontal if the minimum number is 8 (radial). It can cover all directions (360deg). In addition, in the overlapping part of the transmission range of adjacent infrared light, it becomes the characteristic which superimposed both radiation intensity. In this example, in addition to the above arrangement conditions, a predetermined angle is given to the main optical axis of the second light emitting unit 35 with respect to an axis horizontal to the floor surface. Specifically, in consideration of an angle obtained by subtracting an angle component necessary for the ceiling direction (upward) from the half-value angle of the emitted radiation intensity of the second light emitting unit 35, the main optical axis is inclined downward by a predetermined angle. . An axis that is horizontal to the floor, in other words, the angle of the upward component with respect to the radial axis of the virtual circle when the eight second light-emitting parts 35 are connected by lines is determined by the lighting device 2 (for example, shade , The cover) is appropriately determined so as to avoid light interference with the cover.

For example, when an infrared LED having a second emission radiation intensity half-value angle θ1 / 2: ± 27 deg is used as the second light emitting unit 35 and the upward component θu is +2 deg, the main optical axis of the second light emitting unit 35 is the floor. An installation angle θd: -25deg (downward) is rotated with respect to an axis horizontal to the surface. In this way, the effective range of the emitted radiation intensity half-value angle is covered by the infrared light transmitted through the first inner surface 343A up to -52deg (= -25-27deg) in the downward effective component and θu: + 2deg in the upward direction. Can do. Thereby, infrared light can be transmitted to an air conditioner or the like installed near the ceiling.

On the other hand, it is necessary to consider the downward transmission range of infrared light. Here, if the infrared LED is simply installed downward (floor side), the vertical range can be covered, but the number of infrared LEDs increases, resulting in an increase in cost. Therefore, in this example, the light guide component 340 is arranged to emit infrared light, in other words, the second light emitting unit 35 is disposed inside the light guide component 340, and infrared light is not increased without increasing the number of infrared LEDs. Is configured to transmit also in a substantially vertical direction.

The infrared light transmitted through the boundary portion 345 of the light guide component 340 becomes the limit of transmitted light (transmitted component). In FIG. 8, this limit is indicated by the optical axis L1. A part of the infrared light incident from below the boundary part 345 is internally reflected in the light guide component 340 and emitted. At this time, since the parallel surfaces (the second inner surface 343B and the outer surface 344) are formed in the light guide component 340, infrared light internally reflected in the light guide component 340 can be diffused and emitted. . Further, since the R-shaped

portions

346A and 346B are formed, infrared light internally reflected in the light guide component 340 can be further diffused and emitted. Infrared light internally reflected in the light guide component 340 is emitted as a light guide component.

In addition, a component of the infrared light that totally reflects on the surface of the light guide component 340 (a component incident at a critical angle or more) is guided downward as a reflected light component. With this light guide component and reflected light component, it is possible to emit infrared light for an angle range from −52 deg. That leaks from the cover range of the transmissive component to vertically below (−90 deg.). That is, infrared light can be transmitted also to an electric device (a television device or a stationary audio device) located on the floor side, and the electric device can be controlled.

FIG. 10A is a diagram schematically showing a range in which infrared light emitted from the second light emitting unit 35 can be transmitted. FIG. 10B is a diagram schematically illustrating a range in which infrared light emitted from the second light emitting unit 35 can be transmitted in the indoor RO. 10A and 10B show that the above-described range can be covered.

FIG. 11 is a diagram relatively showing the distance that the infrared light emitted from one second light emitting unit 35 reaches for each angle. Here, the longest distance (corresponding to a position of −5 deg in angle) is 100%, and the distances at other angles are relatively shown. As shown in FIG. 11, the infrared light reaches at least 75% or more of the longest distance, and it has been clarified that there is no practical problem.

In the configuration of the electronic device 3 in this example, the reflected light component may be blocked by the speaker net NE. Therefore, a gap may be provided as an example of a passing portion that allows the reflected light component to pass between the light guide component 340 and the speaker net NE. Moreover, you may form the hole etc. which let a reflected light component pass to the speaker net | network NE. Thereby, infrared light can be emitted more effectively on the lower side.

Further, in this example, an example in which a part of the lower housing part 300C functions as the light guide component 340 has been described, but a configuration in which the light guide component 340 is separated from the lower housing part 300C may be used. And the structure which provides locally the light guide component 340 with respect to the infrared light emission direction of the 2nd light emission part 35 may be sufficient.
