(2.2) Shell

The casing 4 houses the control unit 10, the first output unit 11, the second output unit 12, the battery 13, the detection unit 2, the actuating lamp 15, and the circuit board (not shown) on which the control unit 10 and circuit components constituting various circuits are installed. (Pictured) and others are contained inside. Although not shown in the drawings, the various circuits referred to herein are, for example, the following acoustic circuit, first lighting circuit, second lighting circuit, and power supply circuit.

The casing 4 is made of synthetic resin, for example, it is made of flame-retardant ABS (acrylonitrile-butadiene-styrene) resin. The housing 4 is formed in a flat cylindrical shape as a whole. The housing 4 has a mounting portion on its upper surface, and is mounted on one surface (installation surface) of the structure C1 by the mounting portion.

As shown in FIG. 1, the casing 4 has a hole 401 on its peripheral wall 400 that can introduce smoke into a labyrinth provided in the casing 4. The housing 4 has a partition wall that partitions the internal space into two upper and lower partitions. The labyrinth and detection unit 2 are located in the upper first space, and the control unit 10, the first output unit 11, the second output unit 12, the actuating lamp 15, and the circuit board are located in the lower second space.

In addition, the housing 4 has a slit-shaped window 403 that is elongated in one direction (the left and right direction in FIG. 1) on the bottom wall (cover) 402 of the housing 4. The window hole 403 is arranged opposite to the first output portion 11 housed in the casing 4. The window 403 leads the sound output from the first output unit 11 to the outside of the casing 4.

In addition, the housing 4 is attached to the lower wall 402 to support the light-transmitting part 5 in such a way that the lower surface of the light-transmitting part 5 is exposed to the outside of the housing 4. The light-transmitting part 5 is a disc-shaped member having light-transmitting properties. The light-transmitting part 5 is formed of a material such as acrylic resin or glass. The light-transmitting part 5 is arranged opposite to the second output part 12 housed in the housing 4. The light-transmitting part 5 guides the light (illumination light) emitted from the second output part 12 to the outside of the housing 4. In order to distribute the light from the second output portion 12 toward the surrounding area R1, the light-transmitting portion 5 may have a lens portion formed in a convex shape on its outer surface. In addition, a light guide member that efficiently guides the light from the second output section 12 to the light transmission section 5 may be provided between the light transmission section 5 and the second output section 12.

Furthermore, the housing 4 supports the operation button 6 in the lower wall 402 of the housing 4 in such a way that the lower surface of the operation button 6 is exposed to the outside of the housing 4. The operation button 6 accepts operation input from the outside. The operation button 6 can be pushed upward by pressing operation with a user's finger or the like. The operation button 6 is a disc-shaped member with light-transmitting properties. The operation button 6 is arranged opposite to the actuating lamp 15 contained in the housing 4. In addition, the operation button 6 is configured to press a button switch (not shown) housed in the housing 4 by a pressing operation.

In this embodiment, the window hole 403 and the operation button 6 are taken as an example. When the lower surface of the lower wall 402 is viewed from below, the window hole 403 and the operation button 6 sandwich the center of the lower surface of the lower wall 402. Way, arranged in one direction (left and right direction in Figure 1). In addition, the light-transmitting portion 5 is arranged forward of the center of the lower surface of the lower wall 402 when the lower surface of the lower wall 402 is viewed from below.

(2.3) The first output

The first output unit 11 outputs sound (sound wave). When the control unit 10 determines that a fire has occurred, the first output unit 11 outputs an alarm sound to report the occurrence of the fire.

The first output unit 11 is constituted by a speaker that converts electrical signals into sound. The speaker has a diaphragm, and generates an alarm sound by mechanically vibrating the diaphragm in response to an electrical signal. The speaker is formed in a front-view circular shape, which is a disc shape. The first output unit 11 outputs an alarm sound (for example, a "beep" sound) under the control of the control unit 10. The first output unit 11 preferably outputs the alarm sound after changing the size (sound pressure level) of the alarm sound. The alarm sound may include, for example, a sweeping sound that sweeps from the bass to the treble. For example, the alarm sound may also include a sound message of "fire, fire". Here, it is assumed that the alarm sound is composed of a scanning sound and a sound message continuous with the scanning sound.

On the above-mentioned circuit board, for example, circuit components constituting an audio circuit are mounted. The audio circuit has a low-pass filter and amplifier. If the audio circuit receives the PWM (Pulse Width Modulation) signal corresponding to the alarm sound generated by the control unit 10 when a fire occurs, it will be converted into a sinusoidal sound signal by a low-pass filter and amplified by an amplifier. The alarm sound is output from the first output unit 11.

The first output unit 11 also tentatively outputs an alarm sound during operation inspection. The first output unit 11 outputs audio messages such as "normal" or "abnormal" according to the state of the audio device 1. The operation check can be performed by the operation of the operation unit 3. Specifically, the operation check can be performed by a pressing operation of the operation button 6 (operation part 3) or a pulling operation of the cord 7 (operation part 3) derived from the housing 4. The first output unit 11 may also output a voice message reporting the purpose when the battery 13 replacement time is approaching. The battery 13 is, for example, a lithium battery.

In the present embodiment, when the operation unit 3 receives an operation input from the outside during an alarm (while reporting an alarm sound), the first output unit 11 stops the output of the alarm sound.

(2.4) The second output unit (illumination light output unit)

The second output unit 12 outputs illumination light. The second output unit 12, under the control of the control unit 10, outputs illuminating light for illuminating the surrounding area R1 based on the information related to the fire.

The second output unit 12 has one or a plurality of white LEDs (Light Emitting Diode) 12A for illumination mounted on the above-mentioned circuit board as a light source (refer to FIG. 2). The second output unit 12 is extinguished when it is normal (when monitoring a fire), and starts to be lit (output of illuminating light) when it is determined by the control unit 10 that a fire has occurred.

The LED12A is configured as a packaged LED in which at least one LED chip is mounted in the center of the mounting surface of a flat mounting substrate. For example, the LED chip is preferably a blue light-emitting diode emitting blue light from the light-emitting surface. In addition, the mounting surface of the substrate including the LED chip is covered with a sealing resin mixed with a fluorescent substance that converts the wavelength of the blue light emitted from the LED chip. LED12A is constructed by applying a direct current voltage between its anode electrode and cathode electrode to emit white illuminating light from the light-emitting surface. The color of the illuminating light is not limited to white, and may be other light colors. However, it is better not to be covered by the light color of the actuating lamp 15.

On the above-mentioned circuit board, circuit components constituting a first lighting circuit for lighting the LED 12A of the second output unit 12 are mounted. The first lighting circuit uses the DC power discharged from the battery 13 under the control of the control unit 10 to light the LED 12A. When the audio device 1 is electrically connected to a commercial power system, the first lighting circuit converts the AC power supplied from the power system into a DC current to light up the LED 12A.

The light (illumination light) emitted from the second output part 12 is led out to the outside of the housing 4 through the light-transmitting part 5 to illuminate the surrounding area R1 (here, the floor of the bedroom, the bed, etc.). The second output unit 12 is also lit on a trial basis during operation inspection. The operation check of the second output unit 12 can be performed by a pressing operation of the operation button 6 (operation unit 3) or a pulling operation of the cord 7 (operation unit 3), similarly to the first output unit 11.

In this embodiment, when the second output unit 12 receives an operation input from the outside while the operation unit 3 is lighting up during the alarm, it will be linked with the stop of the output of the alarm sound, and the second output unit 12 will be extinguished. In particular, as an example here, the second output unit 12 receives the timing of the operation input at the operation unit 3, and turns off the illumination light. That is, for example, when the resident 100 presses the operation button 6 to the extent that there is no time difference between the operation timing and the turning-off timing, the second output unit 12 turns off the illumination light immediately after the pressing operation.

(2.5) Actuating light

The actuating lamp 15 has a red LED 15A mounted on the above-mentioned circuit board as a light source. The actuating lamp 15 is extinguished when it is normal (during fire monitoring), and starts to flicker (or light up) when it is determined by the control unit 10 that a fire has occurred. If the actuating lamp 15 stops reporting the alarm sound, it will stop blinking under the control of the control unit 10.

On the above-mentioned circuit board, circuit components constituting a second lighting circuit for blinking the LED 15A of the actuating lamp 15 are mounted. The second lighting circuit uses the DC power discharged from the battery 13 under the control of the control unit 10 to blink the LED 15A. When the audio device 1 is electrically connected to a commercial power system, the second lighting circuit converts the AC power supplied from the power system into a DC current to make the LED 15A blink.

The light emitted from the actuating lamp 15 is led out to the outside of the housing 4 through the operation button 6 having light-transmitting properties. Residents 100 can recognize that the audio device 1 is in operation (detecting a fire) by seeing the operation button 6 flashing in red. The actuation lamp 15 also flashes during the operation check. As with the first output unit 11, the operation check of the operating lamp 15 can be performed by pressing the operating unit button 6 or pulling the cord 7 (operating unit 3). In addition, the actuating lamp 15 also flickers when the battery 13 replacement time is approaching or when a malfunction occurs. If the operation unit 3 is operated during the blinking, the first output unit 11 outputs a voice message that conveys that it is close to the replacement time or that a failure has occurred.

(2.6) Detection Department

The detection unit 2 detects a fire as a specific phenomenon. Here, the detecting part 2 is taken as an example, a photoelectric sensor for detecting smoke. As shown in FIG. 2, the detection unit 2 includes, for example, a light-emitting unit 21 such as an LED and a light-receiving unit 22 such as a photodiode. The light-emitting portion 21 and the light-receiving portion 22 are arranged in such a manner that the light-receiving surface of the light-receiving portion 22 is deviated from the optical axis of the irradiated light of the light-emitting portion 21 in the labyrinth of the housing 4. In the event of a fire, smoke can be introduced into the labyrinth through the hole 401 in the peripheral wall 400 of the housing 4.

When there is no smoke in the labyrinth of the housing 4, the irradiated light from the light-emitting part 21 hardly reaches the light-receiving surface of the light-receiving part 22. On the other hand, when there is smoke in the labyrinth of the casing 4, the irradiated light of the light emitting part 21 is scattered by the smoke, and a part of the scattered light reaches the light receiving surface of the light receiving part 22. In other words, the detection unit 2 receives the irradiated light from the light-emitting unit 21 scattered by the smoke by the light-receiving unit 22.

The detection part 2 is electrically connected to the control part 10. The detection unit 2 sends an electrical signal (detection signal) indicating a voltage level corresponding to the amount of light received by the light receiving unit 22 to the control unit 10. The control unit 10 converts the amount of light of the detection signal received from the detection unit 2 into smoke density (phenomenon level) to determine the fire. Furthermore, the detection unit 2 may also convert the amount of light received by the light receiving unit 22 into smoke density and then send a detection signal indicating a voltage level corresponding to the smoke density to the control unit 10. Alternatively, the detection unit 2 may also determine the occurrence of a fire (smoke) based on the amount of light received by the light receiving unit 22, and send a detection signal containing information about the occurrence of the fire to the control unit 10.

(2.7) Control section

The control unit 10 is composed of, for example, a microcomputer mainly composed of a CPU (Central Processing Unit) and a memory. In other words, the control unit 10 is realized by a computer with a CPU and a memory, and the CPU executes a program stored in the memory, and the computer functions as the control unit 10. The program is pre-recorded in the memory here, but it can also be provided via electrical communication lines such as the Internet, or recorded on a non-temporary recording medium such as a memory card.

The control unit 10 controls the first output unit 11, the audio circuit, the second output unit 12, the actuating lamp 15, the first lighting circuit, the second lighting circuit, the detection unit 2, and the like. In addition, the control unit 10 controls a power supply circuit that generates operating power for various circuits from the DC power of the battery 13.

The control unit 10 is configured to receive information related to a fire as a specific phenomenon and determine whether a fire has occurred. Specifically, the control unit 10 monitors the detection signal (information) received from the detection unit 2 to determine whether the level of the phenomenon contained in the detection signal exceeds a threshold. The phenomenon level is as described above, as an example is the smoke density after conversion. However, the phenomenon level may also be the amount of light.

The control unit 10 stores a threshold in its own memory. The control unit 10, for example, periodically determines whether the smoke concentration exceeds the threshold value at a specific time interval. If the primary smoke concentration exceeds the threshold value, it may also determine that a fire has occurred. The specific time interval is, for example, a 5-second interval. Alternatively, the control unit 10 counts the number of times that the smoke density continuously exceeds the threshold value, and when the number of times reaches a predetermined number of times, it may be determined that a fire has occurred. Of course, if the control unit 10 receives the detection signal including the information about the occurrence of a fire from the detection unit 2, it can also directly determine that a fire has occurred.

When the control unit 10 determines that a fire has occurred based on the smoke density, the first output unit 11 starts the output of the alarm sound. Specifically, the control unit 10 generates a PWM signal corresponding to the scanning sound whose frequency linearly changes over time, and outputs it to the acoustic circuit. The above-mentioned PWM signal is converted into a sound signal by an acoustic circuit, and a scanning sound (alarm sound) is output from the first output unit 11. In addition, the control unit 10 generates a PWM signal corresponding to the voice message based on the message data stored in its own memory, and outputs it to the audio circuit. The above-mentioned PWM signal is converted into an audio signal by the acoustic circuit, and an audio message (alarm sound) is output from the first output unit 11.

In addition, when the control unit 10 determines that a fire has occurred based on the smoke density, it starts the light output of the second output unit 12 and the operating lamp 15. Specifically, the control unit 10 transmits a control signal for lighting the second output unit 12 and a control signal for blinking the operating lamp 15 to the first lighting circuit and the second lighting circuit, respectively. When the first lighting circuit receives a control signal from the control unit 10, it causes the second output unit 12 to light up with a constant brightness. When the second lighting circuit receives a control signal from the control unit 10, it causes the operating lamp 15 to blink.

The control unit 10 also determines the smoke concentration during the alarm (in the report of the alarm sound). If the smoke concentration in the alarm is below the reference value, the control unit 10 stops the generation of the PWM signal and stops the output of the alarm sound using the first output unit 11, and also sends the stop signal to the first lighting circuit and the second lighting circuit respectively. In the lighting circuit, the light output from the second output unit 12 and the actuating lamp 15 is also stopped. That is, if the control unit 10 determines that the fire (smoke) has disappeared, it will automatically stop the output of the alarm sound, the output of the illumination light, and the flickering of the operating lamp 15.

In addition, if the control unit 10 turns on the button switch in the housing 4 by pressing the operation button 6 during the alarm, the output of the alarm sound and the output of the illumination light are stopped. If the resident 100 judges that the alarm of the audio device 1 is a false alarm, by pressing the operation button 6, the output of the alarm sound and the output of the illumination light can be stopped at the same time. The output of the alarm sound and the stop of the output of the illumination light can also be realized by the pulling operation of the drawstring 7.

On the other hand, if the control unit 10 turns on the button switch in the housing 4 by pressing the operation button 6 during non-alarm, it executes a specific operation test for operation inspection. The operation test includes a sound output test of the first output unit 11, an illumination light output test of the second output unit 12, a flicker test of the actuating lamp 15, and the like. The action test can also be realized by the pulling operation of the rope 7.

(2.8) Action description

Hereinafter, while referring to the sequence diagram of FIG. 3 and the situation of the bedroom in FIG. 4, the operation of the acoustic device 1 in the event of a fire will be described. Furthermore, in FIG. 4, it is assumed that the resident 100 sleeps in the bed of the bedroom during the late night.

The control unit 10 of the audio device 1 repeats the determination process of whether the smoke density exceeds the threshold value (step S1 in FIG. 3: monitoring) at intervals of, for example, 5 seconds. When the control unit 10 determines that a fire has occurred (step S2 in FIG. 3: fire determination), it outputs the PWM signal to the audio circuit immediately after the determination. The first output unit 11 receives the sound signal converted from the PWM signal by the acoustic circuit, and outputs an alarm sound (step S3 in FIG. 3: sound start). As a result, as shown in Fig. 4, the alarm sound is reported in the bedroom.

In addition, the control unit 10 outputs control signals to the first lighting circuit and the second lighting circuit immediately after the fire is confirmed. Therefore, the second output unit 12 starts to light up (Step S4 in FIG. 3: Start of illumination), and the operating lamp 15 starts to blink (Step S5 in FIG. 3: Start of blinking). As a result, as shown in FIG. 4, the bedroom in a state close to pitch black is brightened by the illumination light of the second output unit 12. In addition, although illustration is omitted, when the control unit 10 determines that the smoke density is below the reference value, the output of the alarm sound, the output of the illumination light, and the flickering of the operating lamp 15 are stopped.

Here, for example, when a fire breaks out in a house in the middle of the night, there is a possibility that after the resident 100 sleeping in the bedroom of the house hears the alarm sound, he gets up in a state of close to darkness, making it difficult to grasp himself instantly. The path and direction from the bed to the door connected to the corridor. In addition, for example, the residents 100 may walk to the wall lamp switch in the dark, and may want to turn on the lighting in the bedroom. Actions until the wall lamp switch is turned on may cause a delay in evacuation. Moreover, if the resident 100 is a hearing impaired, for example, there is a possibility that the occurrence of a fire cannot be noticed by using only the alarm sound (sound). In contrast to this, the audio device 1 not only outputs the alarm sound, but also outputs the illumination light of the second output unit 12, so the residents 100 can instantly grasp the path from the bed to the door connected to the corridor (evacuation path), saving the need to light up The possibility of lighting time in the bedroom becomes higher. In addition, even if the residents 100 are hearing impaired, the possibility of noticing the occurrence of a fire by the illumination light of the second output unit 12 increases. In short, the audio device 1 not only outputs the alarm sound but also outputs the illumination light, so that the evacuation time can be shortened.

In addition, it is assumed that the alarm of the audio device 1 is a false alarm. As an example, the audio device 1 is equipped with a photoelectric detector 2 for detecting smoke, so there is a possibility that cigarette smoke and heat may be mistakenly detected as fire smoke. If the resident 100 judges that no fire has actually occurred, and the alarm of the audio device 1 is a false alarm, he/she performs an operation input to the operation unit 3 (operation button 6 or drawstring 7) (step S6 in FIG. 3: operation). For example, if the operation button 6 is pressed, the button switch in the housing 4 is turned on, and the control unit 10 accepts the output stop command (step S7 in FIG. 3: acceptance). As a result, the control unit 10 stops the output of the alarm sound, the output of the illuminating light, and the flickering of the operating lamp 15 (step S8 in Fig. 3: stop sound, S9: stop lighting, S10: stop flickering).

In this way, the second output unit 12 extinguishes the illumination light in accordance with the operation input to the operation unit 3. That is, regarding the reporting function (output of lighting light) which is different from the alarm sound, the output is also stopped at any timing of the residents 100. Therefore, for example, when the report of the alarm sound is a false alarm, it is suppressed that the illumination light continues to be output after the alarm sound is stopped. As a result, the convenience can be improved.

Furthermore, the first output unit 11 also stops the output of the alarm sound based on the operation input to the operation unit 3. Therefore, for the residents 100, the common operation input to the operation unit 3 can be used to stop both the alarm sound and the illumination light. The output of the person. Therefore, further convenience is improved.

In the basic example, the second output unit 12 turns off the illuminating light at the timing when the operation unit 3 accepts the operation input. That is, the second output unit 12 extinguishes the illumination light immediately after the pressing operation. Therefore, compared with the case where there is a time difference between the operation sequence and the turn-off sequence, convenience is improved, and power consumption can be suppressed.

However, the second output unit 12 may turn off the illuminating light if a certain time T0 (refer to FIG. 5) has elapsed after the timing of the free operation unit 3 accepting the operation input. The certain time T0 is, for example, several tens of seconds.

Hereinafter, the operation of this modified example will be described while referring to the sequence diagram of FIG. 5. Here, it is assumed that the audio device 1 is already in an alarm state. Furthermore, it is assumed that the alarm of the audio device 1 is a false alarm.

The resident 100 performs an operation input to the operation part 3 (the operation button 6 or the drawstring 7) (step S20 in FIG. 5: operation). For example, if the operation button 6 is pressed, the button switch in the housing 4 is turned on, and the control unit 10 accepts the output stop command (step S21 in FIG. 5: accept). Different from the basic example, the control unit 10 of this modified example only immediately stops the output of the alarm sound and the flashing of the actuation lamp 15 (step S22 in FIG. 5: sound stop, S23: flashing stop).

In addition, when the control unit 10 accepts the above-mentioned output stop command, it uses a timer to start time counting (step S24 in FIG. 5: time counting). Then, when a certain time T0 has elapsed, the control unit 10 stops the output of the illuminating light (step S25 in FIG. 5: illuminating stop).

According to this structure, compared with the case where the illumination light is extinguished immediately after the operation of the operation unit 3, the illumination light can be used for a certain period of time T0. For example, when the report of the alarm sound is a false alarm, the resident 100 who was going to bed before the report operates the operation unit 3 until going to bed, the illumination light can be used.

(3.2) Variation 2

In Modification 1, the second output unit 12 continues to light up with a certain brightness during the time sequence when the free operation unit 3 accepts an operation input passes a certain time T0, and turns off the illuminating light when a certain time T0 passes.

However, the brightness of the illuminating light can also be gradually attenuated over a period of time from the time sequence of the free operation unit 3 accepting the operation input to a certain time T0. That is, the time sequence of the illuminating light free operation unit 3 accepting the operation input starts to fade out, and it may disappear after a certain time T0 passes.

Specifically, if the control unit 10 of this modified example determines that a fire has occurred, it generates, for example, a dimming signal (PWM signal) corresponding to a duty ratio of 100% of the dimming level, and outputs the dimming signal to the first lighting. Circuit. Furthermore, when the duty ratio is 0~5%, the dimming level (output level) becomes 100%, and when the duty ratio is above 98% (excluding 100%), the dimming level becomes 5% (lower limit value) ). Moreover, when the duty ratio is greater than 5% and does not reach 98%, the dimming level decreases at a certain rate relative to the increase in duty ratio.

Then, when the control unit 10 receives an output stop command via the operation unit 3, it outputs a dimming signal that gradually increases the duty ratio to the first lighting circuit so that the dimming level is reduced to 5% as a target value. The first lighting circuit reduces the output current to LED12A, and the brightness of LED12A gradually weakens. When the dimming level reaches 5% (lower limit), the control unit 10 outputs a stop signal to the first lighting circuit to completely turn off the LED 12A.

According to this structure, compared with the case where the illumination light is extinguished immediately after the operation of the operation unit 3, the illumination light can be used for a certain period of time T0. In addition, compared with Modification 1, the power consumption can be further suppressed.

(3.3) Variation 3

In the basic example, the operation button 6 and the drawstring 7 for stopping the output of the alarm sound of the first output unit 11 also serve as the operation unit 3 for stopping the output of the illumination light. However, the operation part 3 may be mechanically separated from the operation button 6 and the drawstring 7. The audio device 1 may include, for example, a dedicated dual in-line package switch for stopping the output of the illuminating light as the operating unit 3.

In addition, the audio device 1 may further include a light receiving unit that receives infrared rays output from a remote controller (not shown). For example, the resident 100 can also press the operation button 6 of the audio device 1 to stop the output of the alarm sound, and then press the operation button of the remote control because of leaving the position of the audio device 1, and the remote control sends a stop signal to the light receiving part. 2The output unit 12 goes out. In other words, the functions of the operation unit 3 may also be distributed.

In addition, for example, the output of the alarm sound may be stopped by pressing the operation button 6 shortly, and the output of the illumination light may be stopped by pressing the operation button 6 long.

(3.4) Variation 4

The audio device 1 of the basic example is a stand-alone fire alarm. That is, the audio device 1 of the basic example does not have a communication function for communicating with other fire alarms. However, the audio device 1 may also be a linked type fire alarm that has a communication function for communicating with other fire alarms. Communication can be done wirelessly or wired.

In addition, the audio device 1 may be configured to be able to communicate with equipment other than the fire alarm. Devices other than fire alarms include, for example, mobile terminals (such as smart phones) carried by residents 100 and security monitoring devices installed in houses.

In this case, the function of the operation part 3 to stop the output of the illuminating light can also be installed in a mobile terminal or a safety monitoring device. For example, the resident 100 can also activate the special application software pre-installed on the mobile terminal to perform touch operations on a specific display area within the content displayed on the display screen of the mobile terminal, and the mobile terminal sends a stop signal to Audio device 1. The stop signal may also include both the output stop command of the alarm sound and the output stop command of the illumination light. Or, it is also possible to separately stop the output of the alarm sound and stop the output of the illumination light. There are two of the "alarm stop button" and the "lighting stop button" in the content displayed on the display screen of the mobile terminal The display area, the residents 100 can choose one place.

If the audio device 1 receives a stop signal from the mobile terminal, it can also transmit a stop signal in conjunction with other fire alarms to stop the alarm sounds and illumination lights of a plurality of fire alarms in alarm.

(3.5) Variation example 5

In addition, the audio device 1 may also have the structure shown in FIGS. 6A and 6B (variation 5). The acoustic device 1 of this modification has a circular slit 9 recessed upward on one surface 40 of the casing 4 (the lower surface in FIG. 6A). When the casing 4 is viewed from below, the slit 9 is It is formed along the outer circumference of the circle of the housing 4. The center of the annular slit 9 is approximately the same as the center of the circular outer circumference of the housing 4. The slit 9 is on its inner surface (for example, the inner bottom surface), and has an acoustic hole H1 for guiding the alarm sound to the outside of the casing 4 and a window hole H2 for guiding the illuminating light to the outside of the casing 4. The first output unit 11 (speaker) is housed in the housing 4 so as to face the sound hole H1. The second output portion 12 is housed in the housing 4 so as to face the window hole H2.

According to this modified example, since the sound hole H1 and the window hole H2 are provided on the inner surface of the slit 9, the holes have a structure that is not easily noticeable. Therefore, it is possible to suppress damage to the appearance and shorten the evacuation time.

A plurality of electronic circuits can be concentrated on one chip or distributed on a plurality of chips. A plurality of chips can be concentrated in one device or distributed in a plurality of devices.

Especially in the basic example, the control unit 10 not only judges the fire, but also generates the PWM signal output to the audio circuit, and the dimming signal output to the first lighting circuit. These functions can also be performed by, for example, More than 2 processors are distributed for execution. In addition, the first lighting circuit and the second lighting circuit may be configured as one lighting circuit, for example.

In addition, the acoustic device 1 of the basic example is realized by one device, but it is not limited to this configuration. For example, the control unit 10 of the audio device 1, the first output unit 11, the second output unit 12, the detection unit 2, the operation unit 3, the actuating lamp 15, the first lighting circuit, the second lighting circuit, the audio circuit, and At least one of the functions such as the power supply circuit can also be distributed in more than two devices.
