DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide light for guiding a person, a speaker system, and a guide system.

[0002]

2. Description of the Related Art In an emergency such as a disaster or an earthquake, there is a method of guiding a person to a safe place without intervention of a staff member or the like by installing an evacuation guide light in a prominent place. Many of such evacuation guide lights are designed so as to be conspicuous for their purpose, and many have a display surface. In such an evacuation guide light, simple and clear words and marks are displayed without displaying complicated sentences or detailed explanations so that quick guidance can be achieved. For example, it is often seen that only words such as “emergency exit” and “exit” are displayed, and that an arrow, a running mark, and the like are displayed.

[0003]

However, with conventional evacuation guide lights in which only simple characters and marks are displayed, it is sometimes difficult to quickly guide people in buildings or places with poor visibility. For example, if an emergency exit light labeled "emergency exit" is installed above the emergency exit, the person who is in a location where the emergency exit can be seen can be aware of the position of the emergency exit, but the emergency exit can be recognized. It is not possible for people who are not visible to recognize emergency exits. Specifically, in places where a plurality of objects that are taller than humans are placed, such as a library, with poor visibility, it is difficult to guide people quickly and easily with conventional emergency signs. In addition, even in a place with good visibility, evacuation guidance or the like may not be visible due to the influence of smoke or the like when a fire occurs.

In high-rise buildings and the like, locations such as emergency exits are displayed on a map in the building and indicated in advance, and evacuation guidance lights labeled "emergency exits" are arranged everywhere to provide guidance in an emergency. Some are planned. However, it may be difficult for a person who has fallen into a confusion due to the occurrence of an emergency to grasp the space in the hall and quickly evacuate as described on the map in the hall. In addition, if evacuation guide lights are arbitrarily arranged at a plurality of locations, confusion may be caused on the contrary, and there is a limit to a method for promptly guiding a person without intervention of a human hand.

[0005] The present invention has been made in view of the above problems, and has as its object to guide a person efficiently.

[0006]

In order to solve the above-mentioned problems, the invention according to claim 1 provides a directional speaker (for example, as shown in FIG. 1) for a guide light (for example, an evacuation guide light 1 shown in FIG. 1). An emergency speaker 3) is provided. Here, the directional loudspeaker is intended to include a loudspeaker which outputs a different sound wave in accordance with the direction. For example, a directional speaker that generates a plane wave of sound in one direction may be used. According to such a directional speaker, the output sound is clearly heard by a person existing in the sound direction, and the output sound is difficult to hear for other people. Note that the number of directional speakers provided for the guide light may be one or more.

According to the guide light according to the first aspect, not only can the guide light visually guide a person, but also the person can be guided by sound from a directional speaker, that is, hearing. Further, even in a place where the view is poor, by outputting a sound, it is possible to inform a person of the location of the guide light. For example, when the present invention is applied to an evacuation guide light that displays "emergency exit," if a sound is output by a directional speaker in the event of an emergency, a person who is present in a place where the evacuation guide light is not visible can The direction of the emergency exit with respect to the location can be grasped. Furthermore, if the output direction of the sound of the directional speaker is set to a direction in which the sound is guided, it is possible to guide a person not only by the content of the sound but also by the volume and sound quality such as the strength of the sound and the ease of hearing. For example, when outputting a sound such as "Please go straight", if a person hears a sound during the traveling, the person can determine that the direction is correct, and if no sound can be heard, the person can determine that the direction is wrong.

According to a second aspect of the present invention, the speaker system includes a normal speaker (for example, the normal speaker 4 shown in FIG. 1) and a directional directional speaker (for example, the emergency speaker 3 shown in FIG. 1). It is characterized by the following. Here, the normal speaker may be a directional speaker or a non-directional speaker.

According to the loudspeaker system according to the second aspect, it is possible to use the normal speaker and the directional loudspeaker for guidance in accordance with the content of the sound to be output. For example, when the speaker system according to the present invention is installed in an exhibition or the like, a normal announcement is output by a normal speaker, and a browsing route and the like can be guided by a directional speaker for guidance. In this way, by properly using the speakers to be used in accordance with the output content, it is possible to prevent a person in a position irrelevant to the content of the output sound from feeling unpleasant and to efficiently guide the people. Can be. Alternatively, when the speaker system is installed on an evacuation guidance signboard or evacuation guidance light, the evacuation direction is broadcasted by a directional loudspeaker for guidance in the event of an emergency, and a normal announcement is made by a normal speaker during normal times. By doing so, it is possible to efficiently guide a person to an evacuation site in an emergency, and to appeal to a person about the presence of an evacuation guide light on a regular basis.

When loudspeakers are arranged at a plurality of places, it may be desirable that these loudspeakers are systematically managed. Also, when a disaster such as a fire or an earthquake occurs, it is desired that the fact be promptly notified. For example, when the guide light and the speaker system according to the present invention are arranged in a plurality of places as evacuation guidance equipment, when an emergency occurs, each guide light and the speaker system may output an emergency sound in conjunction with each other. Is preferably set to. Therefore, as in the invention of claim 3,
The guidance system may include one or more guidance lights according to claim 1 and / or one or more speaker systems according to claim 2.

According to the third aspect of the present invention, a plurality of guide lights provided with directional speakers, and a plurality of speaker systems having a normal speaker and a directional loudspeaker for guidance are integrated as one system. Can be managed. Therefore, for example, when the present invention is used as evacuation guidance equipment, when an emergency occurs, the administrator
It is not necessary to input sound data or sound output instructions to each of the guide lights or each of the speaker systems, and it is possible to quickly cope with an emergency.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, a case will be described as an example where the present invention is applied to an evacuation guide light arranged at an emergency exit, but it is not necessary to limit to this.

In the present embodiment, the evacuation guide light includes a guide light displayed as "emergency exit", a speaker for outputting a normal broadcast (hereinafter referred to as a normal speaker), and an evacuation guide light when an emergency occurs. A speaker (hereinafter, referred to as an emergency speaker) for outputting an emergency voice. Further, the evacuation guide light has a switching device that switches sound output between a normal speaker and an emergency speaker. The switching device is
In normal times, the audio signal transmitted from the broadcast control device via a wire or the like is output to the normal speaker, and when an emergency occurs, the sound output to the normal speaker is cut off. Output the sound of

Here, the broadcast control device is a device in which a plurality of evacuation guide lights are connected by wiring, and outputs all audio signals and various instruction signals to each of the evacuation guide lights. The evacuation guidance lights are managed centrally. Specifically, the broadcast control device has a microphone for inputting audio by an administrator, and an input device for specifying a destination of the audio signal, and the audio signal detected by the microphone is transmitted by the input device. This is a device that executes processing for outputting to a designated evacuation guide light.

The means for recognizing an emergency by each evacuation guide light switching device is based on the following two methods. That is,
When an emergency button provided on each evacuation guide light is pressed, or when an emergency occurrence notification signal is received from the broadcast control device, an emergency is recognized. The broadcast control device is connected when a signal indicating that an emergency has occurred is input from the input device, or when a signal notifying the occurrence of an emergency is input from one of the connected evacuation guide lights. An emergency notification signal is transmitted to all the evacuation guide lights. Hereinafter, the present embodiment will be described in detail.

First, the evacuation guide light will be described. FIG.
FIG. 1 is a perspective view showing an example of an external appearance of an evacuation guide light 1 in the present embodiment. According to FIG.
, An emergency speaker 3, a normal speaker 4, and an emergency button device 6. The base 2 mainly includes a sign board 20 displayed horizontally as “emergency exit” and a frame section 22 supporting the sign board 20. The marking plate 20 is a plate-shaped member made of a transparent or translucent resin such as acrylic, and a fluorescent lamp (not shown) is installed inside the base 2. That is, the light of the fluorescent lamp installed inside the base 2 passes through the sign board 20, and the characters displayed on the sign board 20 can be seen even in a dark place.

The frame portion 22 has a box-like substantially rectangular parallelepiped shape having an opening on one surface, and a sign board 20 is provided at the opening. An emergency speaker 3 is arranged at the left end of the upper edge of the edge 24 of the opening surface of the frame 22, and a normal speaker 4 is arranged above the left edge of the edge 24. A switching device 5 for controlling each part of the evacuation guide light 1 is built in the base 2 of the evacuation guide light 1. That is, the switching device 5 is connected to the emergency speaker 3 and the normal speaker 4 by wiring (not shown), and executes a process of switching audio output and the like. Further, the switching device 5 has a connector for connecting to the broadcast control device, and executes communication with the broadcast control device.

The emergency button device 6 is connected to the switching device 5 by wiring 7. The emergency button device 6 has a substantially rectangular parallelepiped shape having an opening on one surface, and an emergency button 60 is installed in the opening. The emergency button 60
When the button is pressed, an emergency signal is output to the switching device 5. A lid 62 made of a transparent resin such as acrylic is connected to one side of the opening of the emergency button device 6 by a hinge so as to be freely opened and closed.

In the present embodiment, a directional loudspeaker having directivity in a sound output direction, in particular, outputting a plane wave in one direction is used as the emergency loudspeaker 3. The normal speaker 4 may be any of a speaker having no directivity, a flat speaker, a micro speaker, and the like, but a directivity speaker similar to the emergency speaker 3 will be used below. The directional speaker used is
Any configuration is possible as long as it has directivity in the sound output direction. An example is shown below.

FIG. 2 is an exploded perspective view showing an example of the internal configuration of the emergency speaker 3, which is described in International Patent Application PCT / JP.
This is according to the invention disclosed in 00/03755.
According to the figure, the emergency speaker 3 mainly includes a yoke 30 made of a rectangular plate-like member made of a magnetic material, and a diaphragm 34. On the upper surface of the yoke 30,
Fixed frame-shaped spacer 32, filled to the permanent magnet M ₁₁ ~M ₃₄ is disposed in the opening of the spacer 32. The thickness of each permanent magnet M ₁₁ ~M ₃₄ is substantially uniform, the permanent magnet M ₁₁ disposed at the four _{corners, M 31, M 14, M} 34 has a triangular prism shape, and the other permanent magnet It has a quadrangular prism shape. Incidentally, the magnetism of the permanent magnets M ₁₁ ~M ₃₄ (N-pole / S pole)
Are arranged so as to be different from the magnetism of the permanent magnets adjacent to each other. For example, a permanent magnet M ₁₃ poles facing the vibrating film 34 is adjacent to the permanent magnet M ₂₃ is an N pole, M _22, M
₂₄ and M ₃₃ , the S pole is arranged so as to face the vibration film 34.

Further, the thickness of the spacer 32 is designed thicker than the thickness of the permanent magnet M ₁₁ ~M _34. Further, the film surface of the vibration film 34 is
The peripheral portion of the diaphragm 34 is fixed so as to vibrate toward and away from the diaphragm. An octagonal coil arrangement portion 36 is provided at the center of the vibration film 34, and the coil arrangement portion 36 is coated with ceramic or resist to increase hardness.
In other words, the blank portion 38 other than the coil arrangement portion 36 on the vibration film 34 has a lower hardness than the coil arrangement portion 36, and is deformed or stretched when an external pressure is applied. And less distortion to external pressure.

[0022] One side of the coil arrangement portion 36 of the diaphragm 34, and the coil C ₁₁ -C ₃₄ with swirling in a substantially square or substantially triangular so as to face the respective permanent magnet M ₁₁ ~M ₃₄ is arranged I have. Incidentally, the winding direction of the coil C ₁₁ -C ₃₄ are
It differs for each polarity of the opposing permanent magnet. For example, if the polarity of the permanent magnet facing the coil is S-pole, the winding direction of the coil is right-handed. If the polarity of the permanent magnet is N-pole, the winding direction of the coil is left-handed. Therefore, the directions of the currents flowing in the adjacent coils are equal on the contact sides. Now, the current flowing through each coil is affected by the magnetic field converging from the N pole to the S pole of the opposing permanent magnet, and a force is applied. Since the flowing directions are equal, the direction of the force applied to each coil is the same for all the coils. In other words,
The portion where the coil is wired on the coil arrangement portion 36 receives substantially the same force everywhere. For this reason, the coil arrangement portion 36 having a high hardness receives a substantially uniform force on one surface, and vibrates substantially in parallel to generate a plane wave.

FIG. 3 is a view showing a partial cross section when the yoke 30 and the vibration film 34 are assembled. According to the figure, the spacer 32 and the peripheral portion 38 of the vibration film 34 are connected by the vibration film connection portion 40. The vibrating membrane connection portion 40 has an elastic portion 42 protruding in a semicircular cross section. That is, the vibration film connecting portion 40 is a frame-like body having a size along the outer circumference of the spacer 32 and the vibration film 34, and has a configuration in which the elastic portion 42 is continuously provided near the middle between the inner circumference and the outer circumference. I have. In this manner, by providing the elastic portion 42 at the joint between the spacer 32 and the vibration film 34, the peripheral portion 38 of the vibration film 34 vibrates more flexibly against a force,
The coil arrangement portion 36 easily vibrates in parallel. Therefore, a more ideal plane wave is generated.

In FIG. 2, the case where the ratio of the length of the long side to the length of the short side of the directional speaker is 4: 3 has been described as an example. The length of which is sufficiently longer than the length of the short side is used. That is, FIG. 2 shows a case where four permanent magnets are arranged in the long side direction and three permanent magnets are arranged in the short side direction, with one permanent magnet as one unit. The number of magnets is made sufficiently larger than the number of permanent magnets arranged in the short side direction. As described above, by designing the shorter side to be shorter and the longer side to be longer, the vibrating film 34 vibrates almost in parallel to the long side direction, but is affected by the fixed portion in the short side direction. In response, it vibrates slightly rounded. Therefore, in the propagation of the plane wave, the diffusion of the sound in the long side direction is small, and the diffusion of the sound in the short side direction is allowed.

In the present embodiment, as described above, the emergency speaker 3 has little sound diffusion in the long side direction (first direction) parallel to the speaker surface, and is parallel to the speaker surface. In addition, a directional speaker that allows sound diffusion in a short side direction (second direction) orthogonal to the first direction is employed. Then, as shown in FIG. 1, the first direction in which the sound is less diffused in the emergency speaker 3 is the horizontal direction,
The emergency speaker 3 is arranged on the left edge of the upper side of the edge 24 so that the second direction allowing sound diffusion is the vertical direction. Thus, by installing the emergency speaker 3 so that the sound is less diffused in the horizontal direction and the sound is diffused in the vertical direction, the output of sound in four directions such as east, west, north and south can be limited, Regardless of the height of the person, the sound information can be transmitted to a person existing in the direction in which the sound is output.

FIG. 1 shows an example in which the emergency speaker 3 is installed at the right end of the upper side of the edge 24. However, the present invention is not limited to this. The direction of the emergency speaker 3 may be set accordingly. In this way, by setting the sound output direction in a direction according to the guidance content, a person can recognize the direction of evacuation by judging the strength of the sound and the easiness of hearing the sound.

When the speaker 4 is usually installed on the base 2, the base 2 is set so that the long side direction is parallel to the vertical direction.
Installed on the right side of. In this way, by setting the long side direction to be vertical, a desired broadcast can be transmitted to people existing around the evacuation guide light 1.

Next, the internal configuration of the switching device 5 will be described. FIG. 4 is a block diagram illustrating an example of a circuit configuration inside the switching device 5. According to the figure, the switching device 5 includes a switching device 50, an emergency audio output device 52, a normal switch 54, an emergency switch 56, and a power supply circuit 58. The normal switch 54 is a normally closed contact (b contact), that is, a closed switch. On the other hand, the emergency switch 56
Is a normally open contact (a contact), that is, an open switch. The power supply circuit 58 is a circuit for supplying power to each unit in the switching device 5.

The emergency signal input from the emergency button 60 is input to the switch 50 and the emergency audio output device 52 and is also transmitted to the broadcast control device 100.
Conversely, when an emergency signal is input from the broadcast control device 100 to the switching device 5, the emergency signal is input to the switch 50 and the emergency audio output device 52.

When an emergency signal is input from the emergency button 60 or the broadcast control device 100, the switch 50 switches between the normal switch 54 and the emergency switch 56, respectively. That is, when an emergency signal is input, the switch 50 opens the normal switch 54, disconnects the connection between the normal speaker 4 and the broadcast control device 100, closes the emergency switch 56, and outputs the emergency audio output device 52 And the emergency speaker 3 are connected.

The emergency voice output device 52 is provided with an emergency button 6
0 or when an emergency signal is input from the broadcast control device 100,
An emergency voice is output to the emergency speaker 3.
More specifically, the emergency sound output device 52 has a storage medium in which emergency sound is stored. When an emergency signal is input, the emergency sound output device 52 reads out the sound data stored in the storage medium and reads out the emergency speaker 3. Output to

With the above configuration, the evacuation guidance light 1 in the present embodiment can output sound by switching between the emergency speaker 3 and the normal speaker 4 depending on whether or not an emergency has occurred. That is, in the case of no emergency, the sound for general broadcast input by the microphone of the broadcast control device 100 is output by the normal speaker 4, and in the event of an emergency, the emergency sound is output by the emergency speaker 3. Can be output. Note that, as described above, the above configuration may be executed by hardware by combining dedicated circuits for executing each process, or may be executed by software.

Next, a connection form of the broadcast control device 100 and the plurality of evacuation guide lights 1 will be described. FIG. 5 is a diagram illustrating an example of a connection form between the evacuation guide lights 1-1 to n and the broadcast control apparatus 100.

The input unit 130 notifies a selection panel for selecting one or a plurality of evacuation guide lights 1 from the plurality of evacuation guide lights 1-1 to n and notifies each of the evacuation guide lights 1 of the occurrence of an emergency. Emergency button and ON / OF of microphone 120
It has a switching button for switching F and a power button. The control unit 140 executes a process of outputting a sound signal detected by the microphone 120 to the evacuation guide light selected by the selection panel of the input unit 130. When the emergency button of the input unit 130 is pressed, or
When an emergency notification signal is input from any of the connected evacuation guide lights 1, an emergency notification signal is output to all the evacuation guide lights 1.

The sound transmitted from the broadcast control device 100 to each of the evacuation guide lights 1 may be not only the sound detected by the microphone 120 but also music or sound recorded in a storage medium or the like in advance. That is, the control unit 140 may read the sound information from the storage medium, convert the sound information into a given sound signal, and transmit the signal to each of the evacuation guide lights 1. Control unit 1
Reference numeral 40 may be a dedicated circuit that executes a process of switching the output destination of the sound in accordance with an instruction signal input from the input unit 130, or may be performed by software using a general-purpose device such as a CPU. .

FIG. 6 shows shelves 80- such as bookshelves and display shelves, which are relatively large, such as libraries and supermarkets.
A plurality of evacuation guide lights 1-1 to 1-9 (hereinafter, referred to as "shelves 80") are provided in a space where the shelves 80 to 1-10 (hereinafter, simply referred to as shelves 80) are arranged.
FIG. 2 is a diagram showing an example in which an evacuation guide light 1) is arranged. In the figure, each evacuation guide light 1 is indicated by an arrow.
The output direction of the sound of the emergency speaker 3 installed in the first embodiment is shown. As shown in the figure, the evacuation guide light 1 is arranged on each passage constituted by individual shelves 80, and the output direction of the emergency speaker 3 is set so that sound is output along each passage. Further, by outputting a sound for urging the user to move in a direction in which the sound can be heard well, the emergency exit 8 can be quickly performed.
2 can be evacuated. As described above, by arranging the evacuation guide light according to the present invention in consideration of the structure of the building and the configuration of the indoor arrangement, it is possible to systematically guide a person to the evacuation site.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the present embodiment, a plurality of evacuation guide lights have been described as being unitarily managed by one broadcast control device, but it is not necessary to connect individual evacuation guide lights, and each A device for voice input may be individually connected.

FIG. 7 shows one evacuation guide light 1
FIG. 2 is a diagram showing an example in which two voice input devices 200 are connected. As shown in the figure, a voice input device 200 includes a microphone 210 for inputting voice and an input button 2 for voice input.
20 and an emergency button 222 are arranged. The input button 220 is a switch for switching on / off of the microphone 210, and is turned on when pressed. The emergency button 222 is a switch for outputting a notification signal of occurrence of an emergency. That is, when the user presses the input button 2
When a voice is input toward the voice input unit 210 while pressing 20, the voice detected by the voice input unit 210 is output from the normal speaker 4. Further, when the emergency button 224 is input, the control unit of the evacuation guide light 1 outputs an emergency voice from the emergency speaker 3.

Further, in the present embodiment, it has been described that the sound input from the broadcast control device is not output after the emergency button is pressed. However, even after the emergency button is pressed, the sound is detected by the microphone. The sound may be output. That is, the output form of the sound input from the outside may be switched from the normal speaker 4 to the emergency speaker 3. Alternatively, it has been described that when a person presses the emergency button 224, the emergency voice stored in the storage medium 54 is output by the emergency speaker 3, but after the person presses the emergency button 224, the voice input When sound is input to the microphone while pressing the button, the control unit of the evacuation guide light 1 may output the sound detected by the microphone from the emergency speaker 3.

It is not necessary to limit the sound output from the emergency speaker 3 to one type, and a configuration may be employed in which a plurality of types of sounds can be output. For example, the control unit 50 may count the time from the occurrence time of the emergency and change the output content according to the elapsed time. For example, a plurality of audio data are stored in the storage medium 54 in association with the output time (calculated from the emergency occurrence time), and the reading unit 52 reads out the corresponding audio data as time elapses. Set. Alternatively, a plurality of audio data is stored in the storage medium 54 in association with the identification code, and the reading unit 52
When an instruction signal and an identification code for changing the audio are input from the external device or another external device, the audio data corresponding to the identification code may be read and output.

Further, in the present embodiment, the case where the emergency is recognized based on the signal of pressing the emergency button or the signal input from the broadcast control device has been described. However, the present invention is not limited to this. May be connected to the switching device 5 to recognize an emergency based on a signal input from the sensor. Although the switching device 5 has been described as being connected to the broadcast control device 100 by wiring to exchange information, information exchange with an external device may be performed by wireless communication. For example, a sound to be output to the normal speaker 4 is transmitted from an external device by a wireless signal, and the switching device 5 receives this signal and outputs the signal to the normal speaker 4. In this way, the configuration may be such that the evacuation guidance light can be controlled from a remote location by mounting the wireless communication means.

Further, in the present embodiment, the description has been made on the assumption that the sign board 20 is projected by a fluorescent lamp installed inside. However, the sign board 20 may be constituted by an electric bulletin board such as an LED monitor. Good. Then, the content of the audio output may be changed in accordance with the change timing of the display content by the electronic bulletin board. Further, when changing the content of the audio output, the output direction of the directional speaker may be changed according to the content.

In this embodiment, two speakers, the emergency speaker and the normal speaker, have been described as being installed in the evacuation guide light. However, only the emergency speaker may be used. That is, it is possible not to output the sound or the voice at times other than the emergency. Alternatively, the emergency speaker may be configured such that it can be attached to and detached from a part of the side of the evacuation guide light so that the sound output direction can be changed as necessary. For example, the frame section 22 of the evacuation guide light 1 and the emergency speaker 3 shown in FIG. Alternatively, a plurality of hooks may be provided on the side surface of the frame portion 22 of the evacuation guide light 1 so that the emergency speaker 3 can be hung, and the location where the emergency speaker 3 is hung can be changed as necessary. .

Further, it is not necessary to limit the number of normal speakers and emergency speakers to be installed in the evacuation guide light, and a plurality of ordinary speakers and emergency speakers may be installed according to the purpose. FIG. 8 is a diagram showing an example in which one normal speaker 310 and two emergency speakers 320 and 322 are installed for one evacuation guide light 300. As shown in the figure, when a character running leftward and a leftward arrow are displayed on the sign board 20 of the evacuation guide light 200, the first emergency speaker 320 is provided on the front edge 24 of the frame 22. A normal speaker 310 is installed, and a second emergency speaker is installed above the left side 26 of the frame 22. At this time, when the above-described directional speaker is adopted, the first and second emergency speakers 320 and 3 are used.
The normal speaker 31 is set so that the long side direction of the
0 is set so that the long side direction is the vertical direction. Then, when an emergency occurs, the first directional speaker 320 outputs a sound such as “Please turn right here”, and the second directional speaker 322 outputs “Advance straight along this sound. Please say "Please." According to such a sound output setting, the person only has to proceed along the direction in which the sound can be heard and according to the content of the sound, and can evacuate without worrying about the correctness of the traveling direction.

Further, in this embodiment, a case has been described as an example where a directional loudspeaker for normal use and a directional loudspeaker for emergency use are installed in the evacuation guide light, but the evacuation guide light is not used. In addition, it goes without saying that the present invention may be embodied as a speaker system combining a directional speaker for normal use and a directional speaker for emergency use. For example, the speaker system according to the present invention may be installed on a signboard having no fluorescent lamp inside.

Although the case where the present invention is applied to an evacuation guide light has been described, it is not necessary to limit to the evacuation guide light. For example, an electronic bulletin board for displaying a message such as "A train is coming soon" may be installed on a platform of a station or the like. A directional loudspeaker for guidance is installed on the electric bulletin board (guide light) so that the direction of direction is parallel to the white line and the yellow line on the platform, and when the train approaches, outputs a voice such as "Please fall inside the white line". Let it. According to such a guide light, information such as "the train is coming" can be notified only to those who need to be notified, and announcements in the station that can be heard from various directions can be reduced. In the above description, the normal speaker and the directional loudspeaker have been described as being switched according to the occurrence of an emergency, but two speakers may be used simultaneously. .

Alternatively, a tour route may be designated in an art museum, a museum, an exhibition, or the like. In such a case, the directions are generally posted by arrows or the like, but many visitors miss the posted directions.
Therefore, if an arrow or the like is displayed on the sign board of the guide light according to the present invention, and a sound such as "Here is the route" is to be output only in a predetermined direction, the sound has passed in the direction in which the sound is output. Only the reader can be informed of the directions, and there is no fear of giving discomfort to other people. As described above, the present invention is not limited to being applied only to dangers or emergencies, but may be used in various other situations.

[0047]

According to the present invention, by using a directional speaker, not only the content of the sound to be output, but also the characteristics of the directional speaker such that the volume and the sound quality vary depending on the direction, the efficiency can be improved. Can guide people. In addition, by arranging such a directional speaker in the guide light, it is possible to provide a guide light that appeals to human hearing and vision.
