[Detailed description of the invention] The invention identifies whether an audible sound belongs to a low, medium, or high range, and based on this identification signal,
The present invention relates to a sound range-sensitive decorative lamp blinking control device that controls the blinking of decorative lamps in charge of at least two of the low, medium, and high sound ranges.

In conventional devices of this kind, the frequency ranges of three types of sound ranges, low, medium, and high, or two types of sound ranges, low and high, are set without considering the human hearing sense. For this reason, even if the audible sound is perceived as mid-range to the human ear, the flashing of decorative lamps, such as the flashing of low-range or high-range lamps, does not match the human sense of hearing, and is This had the disadvantage of giving a sense of discomfort and reducing the decorative effect. In addition, low
The frequency range settings for the three types of sound ranges, medium and high, overlapped or were too far apart, so the lamps for the low, medium, and high sound ranges flashed at the same time or did not flash at all. There was a drawback of doing so.

The present invention has been made to eliminate the above-mentioned drawbacks, and includes at least two of the three filters that identify each of the three sound ranges, low, middle, and high. The boundary of the midrange is set to approximately 300Hz, and the boundary between the midrange and treble range is set to approximately 3000Hz, and at least two of the three types of sound ranges, low, medium, and high, are selected based on the identification signal from the filter. The blinking of the decorative lamps for each sound range is controlled to match the auditory sense with the visual sense, thereby increasing the decorative effect. Here, the reason why the frequency band of approximately 300 to 3000 Hz is defined as the middle range is because the center value of the pitch of a sound that humans do not perceive as high or low is 600 Hz.
The relationship between the psychological scale of audible sound pitch (Mel scale) and frequency is shown in Figure 1, and from this figure,
The frequency of sound that feels twice as high as 600Hz is approximately 2000.
Hz, the frequency of sound that is perceived as half the height is approximately 300Hz, and the human audible range is approximately 20Hz to 20KHz.
When this range is divided into three equal parts on a logarithmic scale, the 1/3rd point is 200Hz and the 2/3rd point is 2KHz, which is the resonance of the human ear canal (a closed tube with a diameter of 0.7cm and a length of about 2.7cm). The frequency is approximately 3KHz to 4KHz, and the frequency of use and volume of the musical instruments are set to be approximately the same.
