Description

A thumb piano that can change color and brightness with the sound

This work is about a musical instrument, especially a thumb piano that can change color and brightness with sound.

The kalimba is commonly known as the thumb piano. Although the thumb piano is a fairly simple and easy-to-learn musical instrument, for people with hearing impairments, because the ability of the ears to receive sound is partially or completely impaired, they cannot learn music normally. Moreover, even if hearing impaired people learn to play the thumb piano, they often lose the fun of playing because they cannot hear the sound melody.

In view of the above-mentioned problems of the prior art, one of the purposes of the present creation is to provide a thumb piano that can produce color and brightness changes with sound, which can not only provide auditory pleasure, but also visual pleasure, so it can be applied to both listening and listening. people and the deaf.

In order to achieve the aforementioned purpose, the present creation proposes a thumb piano that can produce color and brightness changes with sound, at least comprising: a thumb piano with a plurality of keys and a sound box, so that the sound is emitted from the sound box by plucking the keys. Sounds of different scales; a plurality of light-emitting units arranged on the thumb piano, and the light-emitting units correspond to the keys respectively; and a controller controls whether the circuit between the light-emitting units and the keys is not A channel is formed so that when one of the keys is toggled, the light-emitting unit corresponding to the one of the keys will generate light.

The light-emitting units are LED lamps.

The colors of the light generated by the light-emitting units are different from each other.

The resonance box is further provided with a volume sensor for sensing the volume of the sound emitted by the thumb piano.

The controller further adjusts the brightness of the light generated by the light-emitting unit according to the volume of the sound emitted by the thumb piano.

The thumb piano of the present creation, which can produce color and brightness changes with sound, is further provided with a battery that is electrically connected to the controller, the light-emitting units and the volume sensor.

The number of the light-emitting units and the keys are both seven, the colors of the lights produced by the light-emitting units are red, orange, yellow, green, blue, indigo, and purple, respectively, and the scale of the keys is B respectively , G, E, D, F, A, C.

Based on the above, the thumb piano created according to the present invention, which can produce color and brightness changes with the sound, can have one or more of the following advantages:

(1) The thumb piano may be played in the usual way.

(2) When playing different notes, different colors of lights can be produced.

(3) When the strength of playing is different, different light brightness can be produced. The greater the strength, the brighter the light, and the smaller the strength, the darker the light.

(4) People with hearing impairment can also enjoy the fun of playing musical instruments by changing the color and brightness of the bulb.

Please refer to FIG. 1 and FIG. 2. FIG. 1 is a schematic diagram of the appearance of a thumb piano that can change color and brightness with sound, and FIG. 2 is a schematic diagram of the corresponding relationship between the key scale and the color of the light-emitting unit of the thumb piano.

The thumb piano of the present creation, which can produce color and brightness changes with sound, at least includes: a thumb piano 10 having a plurality of keys 12 and a sound box 14 , so that different scales can be emitted from the sound box 14 by plucking the keys 12 A plurality of light-emitting units 20 are arranged on the thumb piano 10, and the light-emitting units 20 correspond to the keys 12 respectively; and a controller 30 controls the relationship between the light-emitting units 20 and the keys 12 Whether the circuit between them is connected, so that when one of the keys 12 is toggled, the light-emitting unit 20 corresponding to the one of the keys 12 will generate bright light.

The light-emitting unit 20 of the present invention can be, for example, an LED lamp. Also, the colors of the lights generated by the light emitting units 20 are different from each other, for example. Each key 12 in the present creation corresponds to one light-emitting unit 20, and the light-emitting units 20 have different colors. For example, as shown in FIG. 2 , the number of the light-emitting units 20 and the keys 12 is seven, and the colors of the light generated by the light-emitting units 20 are, for example, red, orange, yellow, green, blue, Indigo and violet, the scales of these keys 12 are, for example, B, G, E, D, F, A, and C, respectively.

A volume sensor 40 may be further provided in the resonance box 14 for sensing the volume of the sound emitted by the thumb piano 10 . The controller 30 can further adjust the brightness of the light generated by the light-emitting unit 20 according to the volume of the sound emitted by the thumb piano 10 . Therefore, when the user's playing sound is louder, the brightness of the light-emitting unit 20 will be brighter.

The thumb piano of the present invention, which can produce color and brightness changes with sound, can also be provided with a battery 50 that is electrically connected to the controller 30 , the light-emitting units 20 and the volume sensor 40 to provide the required power source.

When the user plays the key 12, the light emitting unit 20 corresponding to the key 12 will light up, and the louder the user plays, the brighter the light emitting unit 20 will be. The hearing-impaired person can also enjoy the fun of playing musical instruments by changing the color and brightness of the light-emitting unit 20 .

In detail, when the user's finger touches the key 12 (eg, the C key) to play the C key, the controller 30 can make the circuit between the battery 50 and the light-emitting unit 20 corresponding to the C key form a path, so as to make the The light emitting unit 20 corresponding to the C key produces bright light. In addition, the volume sensor 40 in the sound box 14 can detect the volume of the sound, and transmit the value to the controller 30 , so as to adjust the brightness of the light-emitting unit 20 .

To sum up, the thumb piano created according to the present invention, which can produce color and brightness changes with sound, can have one or more of the following advantages: (1) The thumb piano can be played in the usual way. (2) When playing different notes, different colors of lights can be produced. (3) When the strength of playing is different, different light brightness can be produced. The greater the strength, the brighter the light, and the smaller the strength, the darker the light. (4) People with hearing impairment can also enjoy the fun of playing musical instruments by changing the color and brightness of the bulb.
