Definitions
- the present invention relates to a sound generating device that can easily reproduce voices and other sounds, does not require an electronic device, and has a very simple configuration.
- a music box that automatically emits a melody in a clockwork mechanism, various electronic music devices, or a sound generator.
- This comprises an article having a space that can resonate with sound, and a string attached to the vicinity of the space, and a concave-convex portion that emits a sound due to abrasion of a toe or the like on the surface of the string by the space. It is arranged and formed from the part side to the free end side. The sound is emitted from the irregularities due to scratching of the toes, etc., and the sound is amplified by resonance in the space.
- the above-mentioned prior art merely states that "sound is produced from the uneven portion due to scratching of a toe or the like", and does not disclose any configuration to be used to generate a desired sound. In fact, it was found that the desired sound or any other sound could not be generated simply by providing the irregularities.
- the present invention has been made to solve such a problem, and requires an electronic device. It is an object of the present invention to provide a technology capable of generating a desired sound in a sound generator and a recording medium having an extremely simple configuration. Disclosure of the invention
- the sound generating device / recording medium is provided when a vibrating member (a member that is susceptible to comparative enemy vibration) on which a graphic that resonates with a frequency component included in a sound or other sound to be expressed is drawn is vibrated. Sound is generated by the vibration of each part on which a figure is drawn.
- the vibration member is, for example, a sheet of paper, plastic, metal, or the like, and selects a member that vibrates by an easy method such as simply rubbing with a finger to realize simple sound generation.
- the sound generation device / recording medium selects a sound or other sound to be expressed, generates and records the sound, performs spectrum analysis of the sound, expresses the image, and displays the image.
- the result of the spectrum analysis is printed and recorded on a recording medium, and a sound is generated by rubbing the surface of the recording medium in a certain direction. As a result, simple sound generation is realized.
- the method of manufacturing a sound generating device / recording medium includes selecting a sound or other sound to be represented, generating and recording the sound, performing spectrum analysis of the sound, expressing the image, and A step of printing and displaying the displayed spectrum analysis result on a recording medium, whereby a simple sound generator can be easily manufactured.
- the recording medium is paper, plastic, metal, or other printable material, can be applied to a wide range of uses, and can be easily mass-produced.
- Examples of images obtained by performing the above-described graphic and acoustic spectrum analysis include, for example, those utilizing a commercially available acoustic analysis program. This is a continuous audio
- the vertical axis represents the frequency distribution of the sound at a certain time
- the horizontal axis represents the time axis.
- a frequency distribution has information on its components corresponding to a certain frequency. Therefore, the image on which the above-mentioned acoustic spectrum analysis is performed is one in which the frequency components are plotted on the frequency temporary plane. Instead of this plot (corresponding to the unevenness), the frequency component may be represented by shading.
- the present invention includes both cases. BRIEF DESCRIPTION OF THE FIGURES
- Figure 1 is an example of a speech spectrum.
- Figure 2 is an IPA consonant chart showing voiced and unvoiced sounds that make up speech.
- Figure 3 shows the spectrum of a 250 Hz voiced sound “aiueo” generated by a woman.
- Figure 4 shows the fricative noise when rubbing a dull printing surface.
- Figure 5 shows a speech spectrum when a sh voice was uttered with a female voice.
- FIG. 6 is an enlarged view showing the details of the “sha” spectrum.
- Fig. 7 (a) is a schematic diagram that more clearly shows the superposition of voiced and unvoiced sounds in the "sh” and “s” lines, and (b) is the unvoiced sound vector in the "t” and "tsj” lines.
- FIG. 8 is a conceptual diagram showing a longitudinal section of a printing paper P (recording medium) in which the spectrum analysis result is printed on a 0.3-mm-thick glossy paper by using water-based ink jet ink.
- Figure 9 shows the test pattern and the spectrum when it was rubbed twice.
- FIG. 10 is a perspective view showing an example of the sound generating means.
- the problem here is how to provide the desired sound by providing unevenness.
- the inventor paid attention to the sound spectrum.
- the horizontal axis represents the passage of time
- the frequency represents the vertical axis
- the shading represents the frequency component corresponding to that time.
- the grayscale is highlighted, indicating that the frequency component in the white part is included in the sound.
- the basic pattern of an adult female voiceprint consists of a frequency band of 250 Hz overtones, and there are 1-3 characteristic bands where the strong part is darkened depending on the words uttered. That part is presumed to be the main component of words. They are common in that they are an aggregate of multiple sound elements. Although the details of the frequency bands are different, the basic structure of the voiceprint is the same. The major difference is that the plastic sound is almost equal in all areas even if it has high and low levels, and there is no characteristic band that can be called strong or weak.
- a tape is applied to the surface of the plastic plate, and sound-emitting and non-sounding parts are alternately provided at appropriate intervals.
- this surface is rubbed, a certain spectrum appears.
- the fricative sound was interpreted as an image pattern, information on the surface of the rubbed plate was reflected in the audio image. This is similar to the case where the sound of the vocal cords and the oral part of the human voiceprint is imaged, just as the sound of the radar bouncing off an object is output as an image. It should be reflected in. It is conceivable that the image processed based on the image information (speech part of voice) of voiceprint analysis is transferred to the material surface, and the characteristic part of voiceprint is reproduced and output from the image.
- Figure 9 shows the spectrum when the test pattern on which the geometric patterns P1, P2, P3, P4, and P5 were printed was rubbed twice, the first and second times. It can be seen that the patterns are almost the same. This means that reproducible sound reproduction is possible.
- a vibrating member When a figure is drawn on a member that is relatively easy to vibrate (hereinafter referred to as a vibrating member) by printing or the like, the vibration characteristics of that part change, and the shape and size of the figure resonate with the frequency components of the sound to be expressed. It can be considered that such vibration characteristics are obtained o
- the vibration of the vocal cords represented by “aiueo” is the main component of the sound, and the voice is characterized by the strength of specific parts of the frequency band.
- sound can be reproduced if the sound information of the transferred image is replaced by vibration.
- the rubbed side is the sound source, and the plastic plate side showed almost no vibration and no sound.
- pudding output capability is 300 dpi at the maximum, but as a result of transferring and trying out audio images at four levels of resolution of 72 dpi—144 dpi—200 dpi—300 dpi, It was confirmed that the reproduced sound became clear in proportion to the resolution.
- Fig. 8 is a conceptual diagram showing the longitudinal section of printing paper P obtained by printing the results of the vector analysis on a 0.3 mm thick glossy paper by water-based bubble jetting.
- Ink I flows from the paper surface S to the inside. Have penetrated. The ink I penetrates deeply in the areas where the ink I is dark (displayed in black) and is shallow in the areas where the ink I is thin (displayed as dot D). When rubbed with a finger, areas where ink I has not penetrated (other white areas) are likely to vibrate, and the deeper ink I penetrates, the more difficult it is to vibrate. In other words, a portion where the ink I does not permeate or has a shallow penetration acts as a pseudo cavity, and a three-dimensional structure is formed which emphasizes a characteristic portion of the voice spectrum.
- the stripe pattern of a spectrum at a certain frequency is composed of the frequencies of its harmonics (400 xn) Hz (n: an integer), and these frequencies are included in the reproduced sound.
- a certain frequency for example, 400 Hz
- the print pattern recorded with the original sound of 250 Hz contains an audio spectrum of (250 X n) (n: an integer) in the audio frequency range of 250 Hz to 22,050 Hz. Only the required frequencies need to be extracted from the reproduced sound. This is called positive processing.
- a method of selectively deleting unnecessary spectral parts based on the information of the image of the voice spectrum can be adopted.
- Figure 1 is an example of saying “a, a, ⁇ , ⁇ , ⁇ j”.
- the printing method include offset printing and a method in which a water-based ink is applied using a bubble jet method.
- Use glossy paper color pudding paper
- water-based ink there is a characteristic that the reproduced voice becomes indistinct as the water content decreases, and offset printing using the oil-based ink has less change over time in sound quality.
- the rubbing direction is the time axis direction in Fig. 1.
- the sound produced by the rubbing method varies considerably, but after a little getting used to it, it can be heard clearly.
- Figure 2 is an IPA consonant table showing voiced and unvoiced sounds that make up speech. Voiced sounds have a regular frequency band, and unvoiced sounds have no fixed frequency.
- Unvoiced consonants are consonants that do not have specific frequency characteristics such as “: f / p / s / ts / t / sh / tsh / k / h”.
- a surface treatment opposite to that of voiced sounds which does not have slip noise and is less likely to cause slipstick phenomena, it is possible to reproduce the fricative sound that is a component sound of unvoiced consonants. For example, when rubbing a matte paper or printing surface, such as a rough paper file, the rubbing sound produced a sound very similar to the sound to be generated.
- FIG. 4 shows the spectrum of the fricative noise when rubbing a dull printing surface.
- Figure 5 shows the speech spectrum when the sh line sound is uttered by a female voice.
- s ha is the superposition of the unvoiced sound “sh” and the voiced sound “a”
- shi is the superposition of the unvoiced sound “sh” and the voiced sound “i”
- shu is the unvoiced sound “ “sh” and voiced sound “uj”
- "she” can be the unvoiced sound “sh” and voiced sound “e”
- sho can be the unvoiced sound "sh” and voiced sound "o”.
- FIG. 6 is an enlarged view showing the “sha” spectrum in detail.
- Figure 7 (a) is a schematic diagram that more clearly shows the superposition of voiced and unvoiced sounds in the “sh” and “sj” lines.
- the black filled area A is the spectrum of the voiced sound.
- the striped part B is an unvoiced sound spectrum.
- Fig. 3 (a) is a spectrum of a voiced sound "aiueo" of 250 Hz generated by a woman
- Fig. 3 (b) is a reproduction when audio is reproduced from an image based on the image information. This is a sound spectrum.
- the sound generating mechanism of the present invention is printed on a product label, and by rubbing this portion, a sound unique to each product, for example, a product name can be generated.
- the sound generating mechanism of the present invention can be applied to an article having a space that can resonate with sound, for example, a doll having a hollow body, a container storing goods, a paper box, and the like.
- an article other than a three-dimensional object such as a magazine MG or the like, in which the page MP is displaced in the back direction BD and distorted to create a megaphone-like space MSP (Fig. 10)
- the sound generation described above significantly Volume was obtained.
- the present invention can provide a new wide range of articles with the auditory pleasure of newly entering from the ears in addition to the conventional visual pleasure, double the interest and enhance the information transmission ability.
- the acoustic spectrum is transferred to paper or the like by printing, it can be manufactured extremely easily and inexpensively. Moreover, the sound can be easily generated simply by rubbing the sounding portion with a fingertip or the like.
