Description

Sound and light conversion teaching aids

The present invention relates to an auxiliary teaching device, in particular to an acousto-optic conversion teaching aid.

For the hearing impaired, "listening" music is an inaccessible dream. Therefore, how to make the hearing-impaired students feel the beauty of music is the goal of the teaching staff.

Therefore, the purpose of the present invention is to provide an acousto-optic conversion teaching aid that can assist the hearing impaired to feel the music.

Therefore, the novel sound and light conversion teaching aid comprises a sound receiving unit, a control unit and a display unit.

The sound unit is configured to receive an external sound and output as a sound signal.

The control unit receives the sound signal, calculates and analyzes the sound signal to obtain the frequency of the external sound, and outputs a light signal according to the frequency of the external sound.

The display unit receives the light signal and displays a light change related to a frequency change of the ambient sound.

The utility model has the advantages that the operation is performed by setting the sounding unit and the control unit, and the display unit is configured to display a light display related to the sound change, thereby achieving the purpose of assisting the hearing impaired person to feel the music.

Referring to FIG. 1 and FIG. 2, an embodiment of the novel acousto-optic conversion teaching aid includes a radio unit 2, a control unit 3, and a display unit 4.

The sound unit 2 is configured to receive an external sound and output it as a sound signal. The sound unit 2 can be implemented using a microphone and convert the external sound into the sound signal that changes in voltage.

The control unit 3 receives the sound signal, calculates the sound signal by Fast Fourier Transform (FFT) and obtains the frequency of the external sound, and outputs a light signal according to the frequency of the external sound. In this embodiment, the hardware of the control unit 3 is implemented using the Teensy 3.2, but the change may be determined according to actual needs, and is not limited thereto.

The display unit 4 receives the light signal and performs a change in brightness, chroma or combination according to the light signal to display a light change related to a frequency change of the external sound. The display unit 4 includes a plurality of light-emitting portions 41 respectively corresponding to different frequencies, and the light-emitting portions 41 are in a key shape, and each of the keys corresponds to a frequency of a note. The display unit 4 displays a lighting effect on the light-emitting portion 41 corresponding to the frequency of the external sound based on the light signal.

In the embodiment, the display unit 4 includes 36 light-emitting portions 41 which are black keys or white keys, wherein the key portions can be designed as light-transmissive materials, and a plurality of WS2812Bs are arranged in the keys. For example, the display unit 4 may be a screen, and the light-emitting portions 41 are different display areas on the screen, and the changes may be determined according to actual needs, and are not limited thereto.

In actual use, the sound unit 2 can be used to collect the music being played, the sound unit 2 receives the sound of the music and converts the sound signal into a voltage change, and the control unit 3 calculates the sound signal by fast Fourier analysis. And obtaining the frequency of the music to output the light signal, so that the light-emitting portion 41 corresponding to the note of the music is illuminated. For example, when the note played at the time is Do, Mi, the sound is received according to the sound-receiving unit 2 After the operation of the control unit 3, the two light-emitting portions 41 corresponding to the Do and Mi frequencies of the display unit 4 are controlled to be illuminated (ie, the oblique line region shown in FIG. 2), so that when the music is played, the students with normal hearing can Listening to the music, and the hearing-impaired students can enjoy the lighting effect of the music playing on the keys. It not only provides the hearing-impaired students with the way to feel the music visually, but also enables the hearing-impaired students and the normal-speaking students to enjoy the music together. situation.

In summary, by setting the sounding unit 2, the control unit 3 to perform an operation, and matching the display unit 4 to display a light display related to a change in sound, the novel acousto-optic conversion teaching aid can indeed achieve an auxiliary hearing impairment. People feel the purpose of music.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
