Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stand with a speaker on which, for example, a keyboard instrument is placed.

[0002]

[Prior art]

 Conventionally, as an example of the above-described speaker-equipped stand, there has been proposed a speaker-equipped stand in which the pillar plates provided on the left and right are connected by a connecting portion, and the speaker is fixed to the connecting portion. As another example, in Japanese Utility Model Laid-Open No. 63-198 098, the upper parts of the strut plates provided on the left and right are connected by connecting members, and the lower parts of these strut plates are connected by pedal box parts. A speaker stand with a speaker fixed to this pedal box has also been proposed. A keyboard instrument is placed on such a stand with a speaker, and when the keyboard instrument is played, the electrical signal output in response to the performance is input to the speaker of the stand with the speaker. Sound is emitted from the speaker. Here, for example, when two speakers are provided in the connection part of the speaker-equipped stand or the pedal box part of the speaker-equipped stand in order to obtain a stereo feeling, the phase of the sound waves emitted from these two speakers is used. A partition plate is provided between these speakers to prevent them from interfering with each other.

[0003]

[Problems to be solved by the device]

 In the speaker stand in which the speaker is fixed to the connecting portion as described above or in the stand with the speaker in which the speaker is fixed to the pedal box part proposed in Japanese Utility Model Laid-Open No. 63-198098, the characteristics of the low range of the speaker are In order to improve, it is preferable that the volume capacity of the connection part and the pedal box part be large, but considering the position of the performer with respect to the speaker stand and the space of the installation place of the speaker stand, the volume capacity of the connection part is considered. There is a problem that the volume capacity of the pedal box part cannot be so large and the bass range characteristics deteriorate.

Further, when these speaker stands are provided with two speakers in the connecting portion or the pedal box portion in order to obtain a stereo feeling, for example, the sound emitted from the two speakers is generated. A partition plate is required between these speakers so that they do not interfere with each other. For this reason, the structure becomes complicated, which causes a problem of cost increase.

In view of the above circumstances, it is an object of the present invention to provide a speaker-equipped stand with improved range characteristics and a simplified structure.

[0006]

[Means for Solving the Problems]

 A speaker-equipped stand according to the present invention that achieves the above-mentioned object is (1) two pillar stands each standing upright on the left and right and each having a hollow cylindrical shape (2) a connecting member for connecting the two pillars to each other (3) It is characterized in that each speaker is fixed to each of the two support columns, and each speaker has a common box for the two support columns.

[0007] Here, it is effective that each of the two support columns has respective standing surfaces facing diagonally forward in a direction facing each other, and the respective speakers are fixed to the respective standing surfaces. is there. Further, it is effective that each of the two support columns has holes on each of the standing surfaces for connecting the inside and outside of the hollow cylindrical body of the support column.

For example, a keyboard musical instrument is placed on the speaker stand of the present invention.

[0009]

[Action]

 In the stand with a speaker of the present invention, since the two support columns also function as the resonance boxes of the speakers due to the above-described configuration, the volume of the resonance box can be compared with, for example, a resonance box including a connecting portion or a resonance box including a pedal box portion. It has a large capacity, which improves the bass characteristics. Further, since the two support columns are erected on the left and right respectively, a partition plate is provided at the connecting portion or the pedal box portion in order to prevent the interference of the phases of the sound waves from the two speakers, as in the conventional technique. The configuration is simple without the need for installation.

Further, each of the two support columns has respective erected surfaces facing diagonally forward in a direction facing each other, and when each speaker is fixed to each erected surface, sound is emitted from each speaker. Sound is transmitted directly to the performer, and the directivity of the sound emitted from each speaker, especially in the high-frequency range, is enhanced, and a sound with a stereoscopic effect close to the original sound is reproduced. When each standing surface has holes for connecting the inside and outside of the hollow cylinder of the support stand, the sound emitted from the back of the speaker and resonated inside the support stand is emitted from the holes. The bass range is enhanced.

【Example】

 Embodiments of the present invention will be described below. FIG. 1 is a perspective view of an embodiment of a stand with a speaker of the present invention. The speaker stand 10 shown in FIG. 1 includes support columns 11 and 12 each having a hollow cylindrical shape standing upright on the left and right sides in FIG. 1, a connecting member 13 that connects the support columns 11 and 12 to each other, and a support column 11. , 12 are used as resonance boxes, and speakers 14 and 15 are provided. Each of the support bases 11 and 12 has standing surfaces 11a and 12a facing diagonally forward in a direction facing each other, and the speakers 14 and 15 are fixed to the standing surfaces 11a and 12a. Further, these standing surfaces 11a, 12a are provided with holes 11b, 12b for connecting the inside and the outside of the hollow cylindrical bodies of the support columns 11, 12, respectively. Further, each of the column bases 11 and 12 includes legs 11c and 12c for stabilizing the respective column bases 11 and 12.

Since each of the column bases 11 and 12 is erected on the left and right in FIG. 1, it is not necessary to provide a partition plate, and the structure is simplified. The support columns 11 and 12 are resonance boxes for the speakers 14 and 15 fixed to the support columns 11 and 12, and have a large volume capacity and improved bass range characteristics. Further, as shown in FIG. 1, since the upright surfaces 11a 1 and 12a of the support columns 11 and 12 are directed diagonally forward toward the performer, the speakers 14 and 15 are exposed. The directionality of the sound being played, especially determined by the high-pitched sound, is enhanced, and a sound with a stereoscopic effect close to the original sound is reproduced.

The upright surfaces 11a and 12a have holes 11b and 12b connecting the inside and outside of the hollow cylindrical bodies of the support columns 11 and 12, respectively, and are so-called bass reflex cabinets. That is, the sound emitted from the back surfaces of the speakers 14 and 15 resonates inside the hollow cylindrical bodies of the support columns 11 and 12, and is emitted from the holes 11b and 12b. Therefore, the bass range is enhanced and the bass reproduction limit is shifted to the bass side.

FIG. 2 is a perspective view showing a state where the keyboard instrument is placed on the stand with the speaker shown in FIG. The keyboard instrument 21 is placed on the above-described stand 10 with the speaker. As shown in FIG. 2, speakers 14 and 15 are fixed to the upright surfaces 11a and 12a of the support columns 11 and 12, and these upright surfaces 11a and 12a face the player. In this way, since the support columns 11 and 12 also serve as the resonance boxes of the speakers 14 and 15, they do not affect the position of the performer or the installation space so much. When the keyboard instrument 21 placed on the speaker stand 10 is played by a player, a sound having a stereoscopic effect close to the original sound is reproduced as described above.

[0015]

[Effect of device]

 As described above, in the stand with speaker of the present invention, since the speaker is fixed to each of the two support columns of the hollow cylindrical body erected on the left and right, the partition plate is not necessary and the structure is simplified. The cost is reduced. In addition, the support base serves as a resonance box, which improves the bass range characteristics. If the speakers are fixed to the standing surfaces of the two support columns that face the front in a slanting direction facing each other, the direction of the sound emitted from each speaker, especially the sound determined by the sound in the high range, is directed. Sound is reproduced with a three-dimensional effect close to that of the original sound. Also, if the holes that connect the inside and outside of the hollow cylinder of the two pillars are provided on the standing surfaces of the two pillars, the bass range will be increased. Is further enhanced.
