A frequency separation unit that separates into three or more divided sound materials, and the divided sound material separated by the frequency separation unit.Each independentlyOutput soundMultiple individualAcoustic conversion means, andIndividualOutput selection means for independently selecting the sound output in the sound conversion means for each divided sound material;Corresponding to the divided sound material, data representing volume and data of separation characteristics such as a cut-off frequency, Q value and gain in the frequency separation means are stored in a storage device, and the frequency separation means is stored in the storage device. The sound source material is separated according to the separation characteristic data, and the volume of each divided sound material is controlled based on the stored data representing the volume.It is characterized by that.
[0006]
  The output selection means isIndividual“Selecting the sound output of the sound conversion means independently for each divided sound material” means selecting whether or not to perform sound output for each divided sound material, and the sound output volume for each divided sound material. In this case, the volume of each divided sound material is controlled to select the volume level, and both are selected. For example, the output selection means may be a switch for turning on / off the sound output for each divided sound material, a volume for controlling the volume of the sound output, or a volume having a switch.

[0030]
FIG. 3 is a perspective view of the speaker units 18A, 18B, and 18C according to the embodiment. Each speaker unit 18A, 18B, and 18C includes a palm-shaped main body 18a and a cylindrical base 18b having a low height. It consists of. The main body 18 a has an upper case 181 and a lower case 182, and a full range speaker 183 is disposed in the upper case 181. An opening is formed in a portion corresponding to the speaker 183 of the upper case 181 and a protective net 184 is disposed. A cable 185 connected to the speaker 183 is drawn from the main body 18a. The cable 185 has a length of about 1 to 2 m, and is connected to the main body 1 of the scene sound material generating apparatus as shown in FIG.
[0031]
The diameter of the pedestal 18b is smaller than the diameter of the main body 18a. When the main body 18a is placed on the pedestal 18b, only the upper edge 18b1 of the pedestal 18b contacts the surface of the main body 18a, and the lower part of the main body 18a The main body 18a is stably held on the pedestal 18b by the weight of the main body 18a and the friction force generated between the main body 18a and the pedestal 18b. Further, although FIG. 2 illustrates an arrangement state in which the speaker is directly above, the main body 18a can be arranged in almost any direction on the pedestal 18b. Thereby, the direction of the speaker 183 can be set arbitrarily. As described above, the speaker units 18A, 18B, and 18C are portable size speakers and can move within an audible range. Since the main body 18a has a spherical shape, it can be reproduced with good frequency characteristics with less diffraction and interference of sound waves.
[0032]
Next, as an example of adjusting the volume of the playback sound, the scene sound as the sound source material is the sound of the shopping street ("Hey, welcome, gayagay, ~ is a good value ~, gayagay, mom, buy this ... ”) As an example. In this case, the low-frequency divided sound material is, for example, a sound centered on a male voice (adult), the middle-frequency divided sound material is, for example, a sound centered on a crowd, and the high-frequency divided sound material is, for example, Sounds like those of children and women. It is assumed that the volume of the speaker units 18A, 18B, and 18C is adjusted to one of “high”, “medium”, and “small”. If the low range is “large”, the mid range is “small”, and the high range is “middle”, the sound (scene) is like a mix of male and child voices. If the low range is “small”, the mid range is “large”, and the high range is “middle”, the sound (scene) will be like a child's voice mixed with the hustle and bustle. If the low range is “middle”, the middle range is “small”, and the high range is “large”, the sound (scene) is like a male voice mixed with a child's voice. When the low range is “large”, the middle range is “large”, and the high range is “large”, it can be reproduced as a crowded sound of a shopping street, that is, a scene sound.
[0033]
In this way, the sound scene represented by the original scene sound (sound source material) can be inferred by adjusting the volume of the low-frequency, mid-range, and high-frequency divided sound materials, and selecting playback on / off. It can be made difficult to guess or gradually become specifiable. Therefore, it is possible to play sounds such as the sound source represented by the original sound source material and the scene, and enjoy not only children but also adults. The volume can be changed in various ways by changing the position, height, or direction of the speaker units 18A, 18B, 18C.

[0035]
In addition to the sound source material, the storage device 21 stores volume data and filter characteristic data as a table corresponding to each sound source material. FIG. 5 is a diagram conceptually showing an example of a sound volume and filter characteristic data table. Each sound source material (source (1), source (2),...) Has a plurality of reproduction patterns (P1, P2, etc.). P3, ...). Each playback pattern has different volume and filter characteristics, and data indicating the volume of “large”, “medium”, and “small” corresponding to each divided sound material of low, middle and high frequencies, and Q value (Q), cutoff frequency (f), and gain (G) filter characteristic data are stored. The data of these tables is read by selecting the sound source material and the reproduction pattern, the volume data is output to the gain setting circuits 26A1, 26B1, 26C1, and the filter characteristic data is the low-pass filter 24A, the band-pass filter. 24B and the high-pass filter 24C.
[0036]
The low-pass filter 24A, the band-pass filter 24B, and the high-pass filter 24C correspond to “frequency separation means”, and the filter characteristics are set according to the filter characteristic data. Then, by extracting the frequency bands of the low frequency, the mid frequency, and the high frequency from the sound source material according to the filter characteristics, the sound source material is divided into waveform data of the divided sound material, respectively. The waveform data of each divided sound material of the low frequency, mid frequency, and high frequency is supplied to the MP3 recorders 25A, 25B, and 25C and stored in the MP3 file format. The MP3 recorders 25A, 25B, and 25C reproduce the stored waveform data as analog audio signals and output the analog audio signals to the amplifiers 26A, 26B, and 26C. The gains in the amplifiers 26A, 26B, and 26C are set by the gain setting circuits 26A1, 26B1, and 26C1 based on the volume data, and the analog audio signals are amplified by the amplifiers 26A, 26B, and 26C, and the speaker units 28A, 28B, and 28C.

MaIn addition, the difficulty level and the fun of the above-mentioned sound play can be set according to the volume data and the filter characteristic data.
[0038]
In the above example, the volume data and filter characteristic data are automatically set (preset) by selecting the sound source material and playback pattern, so the frequency characteristics and playback of each divided sound material are reproduced. The volume of each divided sound material is suitable for the selected sound source material. The volume data and filter characteristic data read from the table may be edited by the user, and the edited data may be set. Further, the volume data and the filter characteristic data may be simply displayed, and the user may be able to set based on this display. Further, the volume data and the filter characteristic data may be presented to the user as a printed matter such as a manual (guidance manual) or a sheet.
