Abstract
A harmonica containing phonetic symbol sensing indicating lamps is provided and comprises a control module and temperature sensors. The harmonica is characterized in that independent temperature sensors are disposed in the sound holes of the harmonica, that twenty four temperature sensors are connected with the twenty four signal ends of the control module, that a double control switch is connected between the positive and negative power ends of the control module and the positive and negative poles of a lithium battery in series, that the twenty four output ends of the control module are respectively connected with the anodes of the LED lamps on a display, and that the cathodes of all LED lamps on the display are connected with the cathode of the lithium battery. When air is blew to musical notes of '1', '3', and '5' , or is absorbed from musical notes of '2', '4', '6', and '7', the temperature sensors transmit new temperature to the control module. Comparing the temperature, the control module converts the color of the LED lamps corresponding to the sound holes into green. When practice is finished, the temperature sensors do not detect new temperature changes so the color of all LED lamps is converted into red. Therefore, independent change of sound hole character color corresponding to the phonetic symbols is achieved when the harmonica is played.
Description
Technical field
The utility model relates to the visual note device of a kind of mouth organ, is a kind of induction pilot lamp phonetic symbol mouth organ concretely.
Background technology
Music is one of traditional Chinese culture, and a lot of people love music, and a lot of beginners do not understand the sound hole on the mouth organ, also be ignorant of how pronouncing, and mouth organ itself is not with any label or indication yet, makes troubles for those mouth organs beginner for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of induction pilot lamp phonetic symbol mouth organ, so that guaranteeing on the basis of former mouth organ function, has and makes things convenient for the beginner to practise the effect of check and correction.
The utility model is realized with following technical scheme: this a kind of induction pilot lamp phonetic symbol mouth organ mainly is comprised of mouth organ, display, lithium battery, control module, temperature sensor, LED lamp, switch.It is characterized in that: the back of mouth organ is fixed with one by rotating shaft can be from the display of 45 ° of backward upper upsets, be equipped with independently temperature sensor in the sound hole of mouth organ, 24 temperature sensors are connected with 24 signal ends of control module, the positive-negative power end of control module is connected in series a double control switch with the both positive and negative polarity of lithium battery centre, 24 output terminals of control module are connected with the positive pole of LED lamp on the display respectively, and the negative pole of all the LED lamps on the display is connected with the negative pole of lithium battery.After opening switch, control module at first detects the temperature of sound hole by 24 sensors, because of ' 1 ' of mouth organ, ' 3 ', ' 5 ' three notes are blown, and ' 2 ', ' 4 ', ' 6 ', ' 7 ' is air-breathing, utilize human body and the extraneous temperature difference to identify, the LED lamp is all lighted and is red simultaneously, when the beginner practises, when running into ' 1 ', ' 3 ', when ' 5 ' note is blown, temperature sensor is delivered to control module to new temperature, after the control module contrast, the LED lamp corresponding with this hole transferred to green, when running into ' 2 ', ' 4 ', ' 6 ', when ' 7 ' note is air-breathing, temperature sensor is delivered to control module to new temperature, after the control module contrast, the LED lamp corresponding with this hole transferred to green, simultaneously ' 1 ', ' 3 ', ' 5 ' pilot lamp transfers redness to, practise complete after, temperature sensor does not detect new temperature variation, all LED lamps all transfer redness to, closing switch, the LED lamp extinguishes, the independent variation of the corresponding sound hole character color of the phonetic symbol when having realized playing wind instruments.
Described LED lamp is the phonetic symbol character shape.
Beneficial effect: the function with the grasp that makes beginner's Simple fast sound hole corresponding with note.
Description of drawings
Fig. 1 is a kind of induction pilot lamp of the utility model phonetic symbol mouth organ structural drawing.
1. mouth organs among the figure, 2. display, 3. lithium battery, 4. control module, 5. temperature sensor, 6.LED lamp, 7. switch.
Embodiment
Figure of description is a kind of structural drawing of responding to pilot lamp phonetic symbol mouth organ of the utility model, its structure by: mouth organ 1, display 2, lithium battery 3, control module 4, temperature sensor 5, LED lamp 6, switch 7 form.In the drawings, the back of mouth organ 1 is fixed with one by rotating shaft can be from the display 2 of 45 ° of backward upper upsets, be equipped with independently temperature sensor 5 in the sound hole of mouth organ 1,24 temperature sensors 5 are connected with 24 signal ends of control module 4, the positive-negative power end of control module 4 is connected in series a double control switch 7 with the both positive and negative polarity of lithium battery 3 centre, 24 output terminals of control module 4 are connected with the positive pole of LED lamp 6 on the display 2 respectively, and the negative pole of all the LED lamps 6 on the display 2 is connected with the negative pole of lithium battery 3.
