Description

The present invention relates to a sound guidance device that guides various information by sound.

Conventionally, sound guidance devices have been used in various fields. For example, in the field of traffic signals, in order to support walking of visually impaired people, voice is output and guided during a green light (see, for example, Patent Document 1). The reproduction time of such voice guidance is limited according to the number of seconds of the light color (green light). Also, in other voice guidance, the playback time is limited depending on the situation of each information.

Japanese Unexamined Patent Publication No. 2006-011600

As exemplified in Patent Document 1, the above-mentioned voice guidance regarding traffic signals is intended to be guided only in Japanese. However, with the recent increase in foreign tourists and residents, guidance in a single language (Japanese) is not sufficient to support foreign pedestrians, and guidance in multiple languages is desired. It is rare.

Therefore, when voice guidance is provided in multiple languages by adding not only Japanese but also foreign languages, voice guidance in a foreign language is usually performed after voice guidance in Japanese. .. However, since the playback time of the voice guidance is limited to, for example, the number of seconds of the light color (green light), as shown in FIG. 4 (b), when the light color changes during the voice guidance in a foreign language, the voice guidance is performed. Was cut off on the way.

The present invention has been made by paying attention to the above-mentioned problems of the conventional technology, and even when voice guidance is performed in a plurality of languages, a necessary message can be transmitted within a range within a predetermined playback time. It is an object of the present invention to provide a sound guidance device capable of outputting all.

The gist of the present invention for achieving the above-mentioned object lies in the inventions of the following items.

The sound guidance device according to the above [1], [2], [3] or [4], wherein the guidance message guides information regarding the operation of the pedestrian signal lamp by voice. (100).

Next, the operation based on the above-mentioned solution will be described.
According to the sound guidance device (100) according to the above [1], the sound generation means (60) outputs a guidance message determined for each information as a voice. As a result, various information can be aurally guided to support the user.

Guidance messages are not limited to one language (for example, Japanese), but are prepared in multiple languages. Therefore, it is possible to provide convenience by voice guidance not only to users who understand one language but also to users who understand only other languages. Here the guide message one language, another reproduction time is long standard patterns, remove some of the contents of the standard pattern also includes a short Kushida shortening pattern playback time.

Generally, the reproduction time of the guidance message is determined according to the amount of information itself to be guided, the time that can be guided according to the situation, etc., and the maximum value thereof is set to a predetermined time in advance. Therefore, the reproduction time of the standard pattern in one language may be set within a range not exceeding a predetermined time. On the other hand, in the shortened pattern, since the guidance message of another language is included within the predetermined time, the extra content is omitted as much as possible to make the playback time the minimum necessary.

Then, the guidance message in another language is set to a reproduction time in which the total of the reproduction time combined with the reproduction time of the shortened pattern in one language falls within the predetermined time. As a result, voice guidance in one language and another language becomes possible without exceeding a limited predetermined time. That is, since the playback time of another language is set within a range within a predetermined time even if it continues after one language, the guidance message of the other language is not interrupted in the middle due to lack of time.

According to the sound guidance device (100) according to the above [2], the sound control means (101, 105) can select in advance a guidance message in only one language and a guidance message in one language or another language. .. Thereby, it is possible to arbitrarily decide whether the output form of the guidance message is limited to one language or a combination of a plurality of languages.

According to the sound guidance device (100) according to the above [3], guidance messages in a plurality of languages are further prepared for guidance messages in other languages other than one language. Therefore, the voice guidance is not limited to the specific two languages, and it is possible to provide voice guidance in a language selected from a larger number of languages according to the installation situation and the area. It should be noted that voice guidance in not only two languages but also three or more languages may be possible as long as the time is within the predetermined time.

According to the sound guidance device (100) according to the above [4], when the outputs of a plurality of guidance messages are duplicated, the sound control means (101, 105) selects a guidance message having a high priority. It is output from the sound generating means (60). As a result, it is possible to avoid a situation in which a plurality of voice guidances are output at the same time and it is difficult to hear any of the guidances.

According to the sound guidance device (100) according to the above [5], the basic components of the device are incorporated in the push button box (10). Therefore, when supporting a pedestrian with a pedestrian signal lamp, it is not necessary to separately install the sound generating means (60) and the sound controlling means (101, 105), and they are installed together with the push button box (10). be able to. In this case, the guidance message provides voice guidance regarding the operation of the pedestrian signal lamp, and in particular, it is possible to enhance the safety of a visually impaired person during walking.

According to the sound guidance device according to the present invention, even when voice guidance is performed in a plurality of languages, all necessary messages can be output within a range within a predetermined playback time, and the user can be surely used in a plurality of languages.

Hereinafter, embodiments representing the present invention will be described with reference to the drawings.
1 to 6 show embodiments of the present invention.
The sound guidance device 100 according to the present embodiment guides various information by sound. Hereinafter, an example in which the sound guidance device 100 is incorporated in the push button box 10 attached to the pedestrian signal lamp will be described.

The push button box 10 instructs the operation of the pedestrian signal lamp. Although not shown, pedestrian signal lights are installed at both ends of a pedestrian crossing, for example, and the color of the lights changes in conjunction with the accompanying traffic signals. In general, pedestrian traffic lights allow pedestrians to pass by lighting blue (green light), blinking blue (blinking blue signal) to announce the timing of the light color change, and lighting red (red light) to allow pedestrians to pass. Is prohibited. The timing of the light color change of the pedestrian signal lamp is controlled by an external traffic signal controller.

The sound guidance device 100 is integrally incorporated in the push button box 10. As shown in FIG. 1, the sound guidance device 100 includes a speaker 60 which is a sound generating means for outputting sound, a control unit 101 which is a sound control means for controlling sound output by the speaker 60, and an acoustic output circuit 105. I have. Here, the control unit 101 not only controls the sound output, but also controls the operation of the entire push button box 10.

In addition to the speaker 60, the control unit 101, and the acoustic output circuit 105, the sound guidance device 100 has an input / output terminal plate 102, a wireless reception unit 103, a time switch circuit 104, and other components common to the pushbutton box 10. It includes an upper switch 40A, a front switch 40B, and a confirmation indicator light 50. That is, the component of the sound guidance device 100 is the component of the push button box 10 as it is.

The control unit 101 has a well-known configuration including a CPU, ROM, RAM, and the like. The CPU performs various operations and controls, and the ROM stores programs, data, and the like related to various operations and control processes. Further, the RAM includes a work area of the CPU including a storage area such as various counters. The CPU of the control unit 101 is connected to an external traffic signal controller, a traffic signal addition device, or the like (not shown) via an input / output terminal board 102.

The input / output terminal plate 102 is supplied with electric power required for operating the pushbutton box 10 from a commercial power source, outputs various signals from the control unit 101 to the outside, and receives various signals from the outside to the control unit 101. It is something to enter. The wireless receiving unit 103 receives an antenna signal from the outside, and the antenna signal is input to the control unit 101. The time switch circuit 104 includes a built-in timer, and by outputting the time switch signal, the output of a specific signal from the control unit 101 can be stopped at an arbitrary time zone.

The acoustic output circuit 105 directly controls the sound output by the speaker 60. Here, the sound output by the speaker 60 includes not only the voice of the guidance message defined for each information, but also non-verbal sound effects, electronic sounds, natural sounds, musical phrases, and the like. When the sound output control signal is output from the CPU of the control unit 101 to the sound output circuit 105, the sound output circuit 105 outputs a sound such as a guidance message. The volume can be set individually for each type of sound.

The acoustic output circuit 105 also has a well-known configuration including a CPU, ROM, RAM, and the like. The CPU executes sound output control and outputs the sound from the speaker 60. Sound processing procedures (programs), data, and the like are stored in the ROM. The RAM stores the information acquired by executing the sound processing procedure by the CPU. Further, the acoustic output circuit 105 is managed by an input / output interface that inputs / outputs signals to and from the control unit 101, a sound control IC that generates a specific sound based on a sound output control signal from the CPU, and a sound control IC, and has a wide variety. It is equipped with a sound data ROM for converting and storing various sounds, an amplifier circuit for amplifying a sound signal generated from a sound control IC, and the like.

In the sound data ROM, for example, sound data such as a position display sound, a confirmation sound, and a voice guidance sound which is a guidance message are stored in advance. Here, the voice guidance sound includes a confirmation guidance sound and a signal guidance sound, which are prepared in Japanese and English as multiple languages, respectively. Furthermore, in Japanese for signal guidance sounds, standard patterns and shortened patterns with different lengths of playback time are prepared. Note that Japanese and English as multiple languages are merely examples, and languages of other countries such as French, German, Chinese, and Korean may be used.

The position display sound is output as, for example, a predetermined melody in order to notify the location of the push button box 10. The sound control means (control unit 101, acoustic output circuit 105) is set so that whether or not to output the position display sound can be selected. The selection here may be performed by, for example, a dedicated switch (not shown) provided on the substrate of the acoustic output circuit 105. When the output of the position display sound is selected, the position display sound is basically always output from the speaker 60, but the sound output control signal sent from the traffic signal addition device or the time switch signal from the time switch circuit 104 Therefore, the output of the position display sound can be stopped at any time zone.

The confirmation sound is output as, for example, an electronic sound (pip-pip-pip, etc.) when the upper switch 40A or the front switch 40B in the push button box 10 is in a sensitive state. However, the confirmation sound is also set so that the output can be stopped at an arbitrary time zone by the sound output control signal or the time switch signal transmitted from the traffic signal addition device. Further, when the upper switch 40A or the front switch 40B detects (at the time of re-sensing) during the output of the confirmation sound, the confirmation sound is set not to be output.

The voice guidance sound guides the operation of the pedestrian signal lamp by voice. The voice guidance sound in the present embodiment includes the confirmation guidance sound and the signal guidance sound illustrated in FIGS. 2 and 3, each of which is prepared in a plurality of languages.
There are two types of confirmation guidance sounds 1 and 2, and when the upper switch 40A and the front switch 40B are in the sensing state, they are output after the confirmation sound has been sounded. However, the confirmation guidance sound is also set so that the output can be stopped at an arbitrary time zone by the sound output control signal or the time switch signal transmitted from the traffic signal addition device.

Specifically, when the upper switch 40A is operated to enter the sensing state, an acoustic signal is output from the control unit 101 via the input / output terminal board 102, and the confirmation guidance sound 1 is output at the time of this recall. Similarly, when the front switch 40B is operated and sensed, a sensitive signal for the elderly or the like is output from the control unit 101 via the input / output terminal board 102, and the confirmation guidance sound 2 is output at the time of this recall. The contents of the guidance messages, which are the confirmation guidance sounds 1 and 2, are prepared in Japanese illustrated in FIG. 2 and English shown in FIG.

There are two types of signal guidance sounds, a pedestrian green signal guidance sound and a pedestrian blue blinking signal guidance sound, and they are output according to a change in the light color of the pedestrian signal lamp. This signal guidance sound is prepared as a "guidance message" in the present invention in a plurality of languages, and in any one of the plurality of languages (Japanese), the length of the reproduction time is within a predetermined time limited in advance. A standard pattern and a shortened pattern having a shorter reproduction time than the standard pattern are included. The signal guidance sound is also set so that the output can be stopped at an arbitrary time zone by the sound output control signal or the time switch signal transmitted from the traffic signal addition device.

Specifically, when the pedestrian signal lamp turns blue (green light), a sound output control signal is sent from an external traffic signal addition device, and when the control unit 101 of the sound guidance device 100 receives this, the pedestrian green signal The guidance sound is output. Further, when the pedestrian signal lamp flashes blue (blinking blue signal), a sound output control signal is transmitted from an external traffic signal addition device, and when the control unit 101 of the sound guidance device 100 receives this, the pedestrian Blinking blue signal The guidance sound is output.

In the Japanese illustrated in Fig. 2, the content of the pedestrian green signal guidance sound is a long sentence and a shortened pattern of "Ping Pong, the signal has turned blue. Let's cross after confirming the safety of the left and right." There is a short sentence "Ping Pong, the traffic light turned blue." Here, the long sentence of the standard pattern is set to a length that fits within the blue lighting (green light) time, which is a predetermined time for which the reproduction time is limited in advance. Further, in the short sentence of the shortened pattern, the playback time is set to a length in which the total of the playback time of the English version described below is within the blue lighting (green light) time.

As illustrated in Fig. 3, the English version of the pedestrian green light guidance sound does not have long and short sentences, but has a uniform voice guidance saying "Please wait until the light turns green." The playback time of the English version is set so that the total of the playback time combined with the playback time of the shortened pattern of the Japanese version falls within the blue lighting (green light) time. As long as the length is within the blue lighting (green light) time, it is not always necessary to match this predetermined time, and the length may be slightly shortened in consideration of the reproduction time of the shortened pattern.

Similarly, as illustrated in FIGS. 2 and 3, Japanese and English versions of the pedestrian blue blinking signal guidance sound are prepared, and in Japanese, there are a standard pattern and a shortened pattern. Then, in the English version, the total of the playback time combined with the playback time of the Japanese shortened pattern is set to the playback time within a predetermined time. The predetermined time here is the blue blinking (blue blinking signal) time, which is shorter than the blue lighting (green signal) time for outputting the pedestrian green signal guidance sound. Therefore, the content of the guidance message of the pedestrian blue blinking signal guidance sound is generally set shorter than that of the pedestrian green signal guidance sound.

As described above, the control unit 101 controls the sound output by the speaker 60 via the acoustic output circuit 105. When a guidance message in only one language is selected as one of such controls, a standard pattern is used. When a guidance message in one language or another language is selected, a guidance message in a shortened pattern is output, and then a guidance message in another language is output in sequence.

Specifically, when the Japanese-only pedestrian green light guidance sound is selected, the control unit 101 outputs a guidance message of a Japanese standard pattern, and the Japanese and English pedestrian green light guidance sounds are selected. If so, the guidance message of the Japanese shortened pattern is output, and then the guidance message of English is output in sequence. The output of the pedestrian blue blinking signal guidance sound is also controlled in the same manner.

The guidance message of only one language (Japanese) and the guidance message of one language (Japanese) and another language (English) can be selected in advance by the sound control means (control unit 101, acoustic output circuit 105). .. Specifically, for example, it may be selected as an initial setting by a dedicated switch (not shown) provided on the substrate of the acoustic output circuit 105, or may be changed later.

By the way, it is possible that the output requests of the above-mentioned confirmation guidance sounds 1 and 2, the pedestrian green signal guidance sound, the pedestrian blue blinking signal guidance sound, and the position display sound overlap with each other in terms of timing. When the output requests for a plurality of sounds are duplicated in this way, it is set to output only one of the sounds. For this reason, the guidance messages for each type of information are prioritized according to the importance of the information.

Specifically, for example, the priority of sound is assumed to be high from (a) as follows. (A) Pedestrian blue blinking signal guidance sound, (b) Pedestrian green signal guidance sound, (c) Confirmation guidance sound 1, (d) Confirmation guidance sound 2, (e) Confirmation sound, (f) Position display sound. When the output requests of a plurality of guidance messages are duplicated, the guidance message having a high priority is selected by the sound control means (control unit 101, acoustic output circuit 105) and is set to be output from the speaker 60. There is.

When any of the voice guidance sounds (a) to (d) and the confirmation sound output request overlap, both the voice guidance sound and the confirmation sound can be output. Further, if there is an output request for the same confirmation guidance sounds 1 and 2 during the output of the confirmation guidance sounds 1 and 2, the subsequent request is invalidated.

Further, the sound control means (control unit 101, acoustic output circuit 105) has a time switch function. That is, the presence / absence of sound output can be set by the built-in time switch circuit 104 and the time switch input from the outside. The time switch circuit 104 can turn on / off the sound output once a day, for example. Further, the time switch circuit 104 is provided with a time switch output and is set so that a time switch signal can be output to another push button box.

As shown in FIG. 5, the pushbutton box 10 has a box-shaped housing 11 that houses the components of the sound guidance device 100 as a main body. The housing 11 includes a base body 20 that is on the back side and has an opening on the front side, and a front case 30 that is combined so as to cover the opening of the base body 20 from the front. An upper switch 40A and a front switch 40B are provided above and below the front case 30, and these are collectively referred to as a switch 40. The switch 40 is composed of a contact-sensing sensor switch that does not need to be pressed during operation and can be operated simply by touching it.

The outer surface of each surface of the housing 11 is a smooth flat surface without protrusions, and the corners where the two or three surfaces are joined are rounded for safety. Further, the upper surface of the housing 11 is inclined diagonally backward and downward, so that it is difficult to place foreign matter. The base body 20 is a case-shaped member having an opening on the front side, and the front case 30 is a lid-shaped member having a shallow bottom that opens on the back side and covers the opening peripheral edge of the base body 20. The upper switch 40A is arranged on the inclined surface of the upper front surface of the front case 30, and the front switch 40B is arranged on the vertical front surface of the lower front surface of the front case 30.

Since the inclined surface on the upper front surface of the front case 30 is in a position or direction that is easy for the visually impaired to touch, the upper switch 40A is set especially for the visually impaired. On the other hand, the front switch 40B at the lower front of the front case 30 is set for a healthy person or an elderly person. Further, on the front surface of the front case 30, a confirmation indicator lamp 50 is arranged between the upper and lower switches 40A and 40B. The confirmation indicator light 50 is controlled to be turned on by, for example, a display drive signal transmitted from a traffic signal controller, but may be configured to be able to display various information regarding the operation of the pedestrian signal light device.

Among the sound guidance devices 100, the control unit 101, the input / output terminal board 102, the wireless reception unit 103, the time switch circuit 104, the acoustic output circuit 105, and the like are configured in a state of being incorporated on one control board 100a. As shown in FIG. 6, the control board 100a is arranged inside the back surface of the base body 20. Further, although the speaker 60 has been conventionally arranged on the control board 100a, in the push button box 10 according to the present embodiment, as shown in FIG. 6, the speaker 60 is not on the control board 100a but on the inside of the front case 30. It is arranged.

Next, the operation of the sound guidance device 100 according to the present embodiment will be described.
According to the real intention guidance device 100, a guidance message defined for each information regarding the operation of the pedestrian signal lamp is output by voice from the speaker 60 provided in the push button box 10. As a result, various information can be audibly guided to support the user, particularly the visually impaired, and the safety during walking can be enhanced.

The basic components such as the speaker 60, the control unit 101, and the acoustic output circuit 105 in the sound guidance device 100 are all incorporated in the housing 11 of the push button box 10. Therefore, when providing pedestrian support in the pedestrian signal lamp, it is not necessary to install the speaker 60 and the sound control means separately from the push button box 10, and they can be installed together with the push button box 10.

As shown in FIGS. 2 and 3, the confirmation guidance sound and the signal guidance sound, which are the most important in the guidance message, are not limited to one language (Japanese), and an English version is also available. Here, there are two types of signal guidance sounds, a pedestrian green signal guidance sound and a pedestrian blue blinking signal guidance sound. In addition to the standard pattern for long sentences with a long playback time, a shortened pattern for short sentences with a short playback time is prepared for each. Has been done.

The reproduction time of the pedestrian green light guidance sound is limited to a predetermined time while the pedestrian signal lamp is lit in blue (green light). Therefore, as shown in FIG. 4A, the reproduction time of the standard pattern (see FIG. 2) of the pedestrian green light guidance sound in Japanese is determined within a range not exceeding a predetermined time. On the other hand, the shortened pattern (see FIG. 2) is set to the minimum necessary playback time with as little unnecessary guidance as possible because the English guidance message (see FIG. 3) is also sequentially output within a predetermined time.

In the English version of the pedestrian green light guidance sound, as shown in FIG. 4C, the total of the reproduction time combined with the reproduction time of the Japanese shortened pattern is set in advance to the reproduction time within a predetermined time. As a result, voice guidance in Japanese and English becomes possible within a limited predetermined time. That is, since the playback time of another language is set within a predetermined time even if it continues after one language, the guidance message of the other language is cut off in the middle due to lack of time as shown in FIG. 4 (b). Will not be done.

When the guidance message only in Japanese is selected by the control unit 101 and the acoustic output circuit 105 that form the sound control means, the guidance message in the Japanese standard pattern is output. On the other hand, when Japanese and English guidance messages are selected, guidance messages in Japanese abbreviated patterns are output, and then guidance messages in English are sequentially output. This makes it possible to provide convenience by voice guidance not only to users who can understand Japanese but also to users who can only understand English.

It is possible to select in advance whether to output the guidance message only in Japanese or the guidance message in Japanese and English. Therefore, it is possible to arbitrarily select whether the output form of the guidance message is limited to one language or a combination of a plurality of languages. The selection here may be selected as the initial setting by a dedicated switch (not shown) provided on the substrate of the acoustic output circuit 105 as described above, or may be changed later. .. In addition, the number of seconds of the light color of the previous pedestrian signal may be learned, and the short sentence, the long sentence, and the language may be determined based on the number of seconds.

In addition, although two languages, Japanese and English, are illustrated as multiple languages, guidance messages in other languages other than Japanese (one language) include French, German, Chinese, Korean, etc. in addition to English. The guidance message in a plurality of languages may be stored in the sound data ROM of the acoustic output circuit 105. Also in this case, any one of a plurality of languages other than one language can be arbitrarily selected as another language.

Specifically, for example, one of a plurality of languages may be selected as the initial setting by a dedicated switch (not shown) provided on the substrate of the acoustic output circuit 105, or can be changed later. It doesn't matter. In addition, the face image of the user may be recognized to determine an appropriate language, or the push button switch may be a touch panel type so that the user can select the language. It is also possible to configure the pushbutton box to notify the requested language using an application such as a smartphone.

Further, the "one language" among the plurality of languages is not limited to Japanese, and other languages may be appropriately selected according to the installation location and area. In this case, in addition to the basic standard pattern, a shortened pattern will be prepared for all of the plurality of languages. Then, in any combination of each language, the total of each reproduction time may be set so as to be within a predetermined time limited in advance.
Although the pedestrian green signal guidance sound has been described above as a representative, the pedestrian blue blinking signal guidance sound is also controlled in the same manner as the pedestrian green signal guidance sound.

The timing at which the pedestrian green light guidance sound is output is due to the change in the color of the pedestrian signal lamp. That is, when the pedestrian signal lamp is lit in blue (green signal), a sound output control signal is transmitted from an external traffic signal addition device. When the control unit 101 of the sound guidance device 100 receives this sound output control signal, the sound output control signal is input to the sound output circuit 105. Then, under the control of the CPU of the acoustic output circuit 105, the audio control IC refers to the audio data ROM to generate a pedestrian green signal guidance sound, which is output from the speaker 60 via the amplifier circuit.

Here, when the guidance message only in Japanese is selected by the acoustic output circuit 105, the guidance message in the standard Japanese pattern is output (see FIG. 4A). On the other hand, when Japanese and English guidance messages are selected, guidance messages in Japanese abbreviated patterns are output, and then guidance messages in English are sequentially output (see FIG. 4C).

Further, when the pedestrian signal lamp becomes blue blinking (blue blinking signal), the pedestrian blue blinking signal guidance sound is generated and output from the speaker 60 through the same control flow as the pedestrian green signal guidance sound. .. Similarly, for the selection of guidance messages in Japanese only or in Japanese and English, the one selected in advance is output.
The output of these signal guidance sounds can be stopped at an arbitrary time zone by the sound output control signal transmitted from the traffic signal addition device or the time switch signal from the built-in time switch circuit 104.

In addition to the signal guidance sound, the voice guidance message also includes a confirmation guidance sound. When the upper switch 40A is operated to enter the sensing state, an acoustic signal is output from the control unit 101 to the external traffic signal addition device via the input / output terminal board 102. Based on this acoustic signal, first, a confirmation sound (such as pip pip pip) notifying the sensing state of the upper switch 40A is output, and then the confirmation guide sound 1 illustrated in FIG. 2 or 3 is output.

Similarly, when the front switch 40B is operated to enter the sensing state, a sensitive signal for the elderly or the like is output from the control unit 101 to the external traffic signal addition device via the input / output terminal board 102. Based on this sensitive signal for the elderly, etc., a confirmation sound (pip-pip-pip, etc.) is first output, and then the confirmation guide sound 2 illustrated in FIG. 2 or 3 is output. Regarding the confirmation guidance sounds 1 and 2, not only the Japanese illustrated in FIG. 2 but also English as one of the multiple languages as illustrated in FIG. 3 is prepared in advance as in the case of the signal guidance sound. Be selected.

However, regarding the confirmation guidance sounds 1 and 2, the reproduction time of the guidance message is shorter than that of the signal guidance sound in both the Japanese and English versions. Therefore, it is not necessary to prepare a Japanese abbreviation pattern in particular, and even if the two languages are sequentially output, it can be stored within a predetermined time.
The output of the confirmation guidance sounds 1 and 2 can also be stopped at an arbitrary time zone by the sound output control signal transmitted from the traffic signal addition device or the time switch signal from the built-in time switch circuit 104.

In addition, the speaker 60 of the push button box 10 outputs a position display sound indicating the location of the push button box 10, but the position display sound can be selected not to be output in advance if it is unnecessary. .. Further, even when the position display sound is selected to be output, the position display sound is generated in an arbitrary time zone by the sound output control signal transmitted from the traffic signal addition device or the time switch signal from the time switch circuit 104. Output can be stopped.

Further, when the output requests of the above-mentioned confirmation guidance sounds 1 and 2, the pedestrian green signal guidance sound, the pedestrian blue blinking signal guidance sound, and the position display sound overlap, the sound control means (control unit 101, acoustic output circuit 105). ) Selects any one type of guidance message having a high priority as described above, and outputs the guidance message from the speaker 60. As a result, it is possible to avoid a situation in which a plurality of voice guidances are output at the same time and it is difficult to hear any of the guidances.

However, since the confirmation sound is a simple and short electronic sound, if any of the confirmation sound, the confirmation guidance sounds 1 and 2, the pedestrian green signal guidance sound, and the pedestrian blue blinking signal guidance sound overlap, these Both the voice guidance sound and the confirmation sound are output. Further, if there is an output request for the same confirmation guidance sounds 1 and 2 during the output of the confirmation guidance sounds 1 and 2, the subsequent request is invalidated.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to the embodiments as described above, and there are changes and additions within a range that does not deviate from the gist of the present invention. Is also included in the present invention. For example, the sound guidance device 100 is not only used for pedestrian support in the push button box 10, but also provides various support such as guidance at the entrance or entrance of a building, ATM operation guidance, use of an elevator, and equipment guidance in a toilet. It can be used for equipment.

The sound guidance device according to the present invention can be widely applied to a support device that guides various information by sound, and is particularly suitable as a pedestrian support device in a push button box attached to a pedestrian signal lamp. ..
