Description

  The present invention relates to a voice volume display device for quantitatively displaying a loudness level of a speaker.

  In recent years, the presence of children with developmental disabilities has become apparent, but there are many children with developmental disabilities who are unable to adjust the volume of their voice (voice volume) according to the situation. In situations where you should be quiet, you may unintentionally make a loud voice.

  For this reason, in the conventional education field, “voice ruler” which is a paper-based teaching material for teaching the loudness of voice is used. This educational material is a paper-based bulletin board that categorizes and displays 3 to 5 levels of the amount of voice used in daily life. For example, a guideline such as 1: a voice of a secret story, 2: a voice when talking with two people, 3: a voice when talking in a group, 4: a voice when talking to everyone in the class, and 5: a voice when playing in a playground is described.

  On site, this “voice measure” was posted on the blackboard, etc., and the students were given the task of reading the textbook aloud. "Let's read it with a little smaller 3", and the teachers are teaching the children with developmental disabilities to get a sense of volume control.

  However, in the teaching using this “voice measure”, the teacher had to evaluate the voice volume of the child subjectively, and the criteria for indicating the loudness of the voice were ambiguous. In addition, children with developmental disabilities themselves could not evaluate and judge their own voice volume.

  On the other hand, a volume measuring device (sound meter) that measures the volume of noise or the like and displays the volume in decibel (dB) units has been widely provided, and is disclosed in Patent Document 1, for example. If a volume measuring device is used, it is possible to measure voice volume quantitatively.

  However, even if the volume of sound is displayed in decibels using a volume meter, children with developmental disabilities cannot determine whether their own volume is appropriate just by looking at the numbers. It is difficult to get a sense of In addition, volume measuring instruments are often expensive and difficult to use easily in educational settings.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide an inexpensive voice volume display device capable of easily displaying whether or not the voice volume is appropriate.

  In order to solve the above-mentioned problems, a voice display device according to the present invention is a voice display device for displaying a voice level, a microphone, three or more light emitting members, and an input input via the microphone. And a control circuit for causing the light emitting member to emit a predetermined number of lights according to a volume level.

  According to the voice volume display device according to the present invention, whether or not the voice volume is appropriate can be easily displayed by an inexpensive voice volume display device.

FIG. 1 is an external perspective view of a voice display device according to the present embodiment. FIG. 2 is a block diagram showing a circuit configuration of the voice volume display device according to the present embodiment. FIG. 3 is a diagram showing the set volume of each LED set in the control circuit according to the present embodiment.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external perspective view of a voice display device according to the present embodiment. FIG. 2 is a block diagram showing a circuit configuration of the voice volume display device according to the present embodiment.

  The voice display device 1 includes a housing 5, a microphone 10, a control circuit 11, a power switch 13, and eight LEDs 15. The housing 5 is a rectangular parallelepiped plastic case, and includes a microphone 10 and a control circuit 11 therein.

  A sound passage hole 6 for the microphone 10 is formed on the front surface of the housing 5, and three illustrations 7 for explaining the voice level in an easy-to-understand manner are drawn. Illustration 7-1 shows that the voice is small and difficult to hear, illustration 7-2 shows that the volume of the voice is just right, and illustration 7-3 shows that the voice is too loud. Along with the number of LEDs 15 to be turned on, the child with developmental disabilities can be made to understand the level of his / her voice in an easy-to-understand manner.

  The microphone 10 is installed inside the housing 5 inside the sound passage hole 6, and takes in sound pressure and converts it into an electrical signal. The control circuit 11 is connected to the microphone 10, the power switch 13, and the eight LEDs 15, and controls to turn on a predetermined number of LEDs 15 according to the volume level detected via the microphone 10.

  In the control circuit 11, a set volume that is a reference for causing each LED 15 to emit light is set. Then, when the control circuit 11 detects that the input volume input via the microphone 10 is equal to or higher than the set volume, the control circuit 11 controls to turn on the relay for connecting to the LED 15 and turn on the LED 15. . As the control circuit 11, for example, a noise level relay kit (UR-S1) manufactured by Wonder Kit or a compact level meter kit (SK-LV39) manufactured by Silicon House can be used.

  Further, the control circuit 11 is configured to turn on the relay and turn on the connected LED 15 for the time set by the timer (timer set time) after detecting the set volume. In the present embodiment, the timer setting time can be arbitrarily set from 1 to 11 seconds, and is set to 2 seconds, for example. However, if the set volume is detected again during light emission, the timer set time is set again and the light emission time is extended.

  In this way, not only when the set volume is detected, but also by turning on the LED 15 for a predetermined time after the detection, the child with developmental disabilities can slowly confirm the loudness of the voice and reliably recognize it. Note that even if the timer setting time is too long, it is difficult to know when the spoken voice was loud, so it is desirable to set this timer setting time within 1 second to 20 seconds.

  The power switch 13 is a button type switch for turning on / off the power of the voice display device 1, and can be switched on and off by pressing the power switch 13.

  The LED 15 is composed of eight light emitting members, a first LED 15-1 to an eighth LED 15-8, which are arranged in a horizontal row so that a light emitting portion protrudes from the front surface of the housing 5, and the first LED 15- from the left side of FIG. 1st-5th LED15-5 is green LED15, 6th LED15-6-8th LED15-8 is red LED15. Each of the LEDs 15-1 to 15-8 is independently controlled to be lit under the control of the control circuit 11.

  Next, details of the control method of the control circuit 11 will be described with reference to FIG. FIG. 3 is a diagram showing a set volume that is a reference for turning on each LED 15 set in the control circuit 11 according to the above-described embodiment. The upper row shows the number of the LED 15, and the lower row shows each LED 15-1. The set volume x (dB) at which 15-8 is lit is shown.

  As shown in the figure, the first LED 15-1 is always lit while the power switch 13 is pressed and the apparatus is turned on. The second LED 15-2 is controlled to light up when the input volume x input through the microphone 10 is 66 dB or more. Similarly, the third LED 15-3 is controlled to be lit when 72 dB or more, the fourth LED 15-4 is 78 dB or more, and the fifth LED 15-5 is 84 dB or more.

  Further, the sixth LED 15-6 is controlled to be turned on when it is 90 dB or more, the seventh LED 15-7 is 96 dB or more, and the eighth LED 15-8 is 102 dB or more. That is, as the volume increases, the number of LEDs 15 that light up toward the right side in the figure increases stepwise.

  Here, as a general measure of noise, 40 dB is quiet (library, quiet residential area), 50 dB is normal (quiet office), 60 dB is a little worrisome (quiet passenger cars, Normal conversation), 70dB is noisy (telephone bell, noisy office, noisy street), 80dB is very noisy (subway car, boulevard during the day, hail), 90dB is very noisy It is said that it is noisy (speaker of election car, noisy factory, yelling voice), and if it is 100dB, it feels painful (under guard when the train passes).

  Therefore, in the present embodiment, it is preferable that the volume of voice detected by the microphone 10 is about 66 to 84 dB as the volume of voice when speaking in the classroom, and the LED 15 is lit stepwise at the set volume described above. Configured.

  As shown in FIG. 1, the first LED 15-1 is positioned above the illustration 7-1 indicating that the voice is low, and the fourth above the illustration 7-2 indicating that the volume of the voice is just right. The seventh LED 15-7 is located above the illustration 7-3 indicating that the LED 15-4 is located and the voice is loud.

  Thereby, the person who is looking at the voice display device 1 recognizes that the voice is low when only the first LED 15-1 is lit, and when it is lit to the vicinity of the fifth LED 15-5. Recognizes that the loudness of the voice is just right, and can recognize that the voice is too loud when it is lit up to the vicinity of the seventh LED 15-7. Further, the sixth to eighth LEDs 15-6 to 8-8 are red LEDs and can be visually recognized that the voice is too loud by being lit red.

  The configuration of the voice volume display device 1 according to the present embodiment has been described in detail above. Next, the usage mode of the voice volume display device 1 will be described. In the present embodiment, a case will be described in which a child with developmental disabilities uses the voice display device 1 placed on a desk in a classroom.

  The voice display device 1 is assumed to be used at a distance of about 50 cm from the human mouth. The voice display device 1 is placed on the desk at a distance of about 50 cm from the mouth of the seated child. Arrange and press the power switch 13 to turn on the power.

  In this state, when the child speaks, the voice is input to the voice volume display device 1 through the microphone 10, and the control circuit 11 controls the predetermined number of LEDs 15 to emit light according to the level of the voice volume (volume). To do.

  For example, if the voice is small and the voice volume is 60 dB, the control circuit 11 refers to the set volume shown in FIG. 3 and since no set volume is exceeded at 60 dB, only the green first LED 15-1 is used. Lights up. At this time, when the child checks the voice display device 1, only one LED 15 is lit, and his / her voice is seen by looking at the illustration 7-1 below the lit first LED 15-1. Can be recognized as small.

  Further, if the voice is loud and the voice volume is 100 dB, the control circuit 11 has a green first to fifth LED 15-because the set volume of the second to seventh LEDs 15-2 to 15-7 is exceeded at 100 dB. 1 to 15-5 and red sixth and seventh LEDs 15-6 and 15-7 are turned on. At this time, when the child checks the voice display device 1, the red LED 15 is lit, and by seeing the illustration 7-3 located below the lit seventh LED 15-7, his / her voice is heard. It can be recognized that it is too large.

  Although the voice volume display device 1 has been described in detail above, according to the present embodiment, it is easy to understand whether or not the volume of the voice volume is appropriate for a child with developmental disability based on the number and color of the LEDs 15 to be lit and the illustration 7. It can be displayed in real time, and the child can learn by himself without depending on a teacher or the like for an appropriate voice volume.

  In addition, since the members constituting the voice volume display device 1 are small and can be obtained at a low cost, it is possible to easily display whether the voice volume is appropriate with a small and inexpensive device, such as educational institutions and homes. Can be purchased and used easily.

  Although the present embodiment has been described in detail above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the number of LEDs and illustrations can be changed as appropriate. However, in order to display the appropriateness of voice volume, it is desirable to install at least three LEDs.

  Moreover, in the said embodiment, although LED (light emitting diode) is used as a light emitting member, you may use other light emitting members, such as an incandescent lamp.
