1 to 3, the resonance modular furniture 100 having an acoustic function may include an upper frame 110 and a lower frame 130.

The upper frame 110 may be partially or wholly opened, have a first through hole H1 formed on the lower surface 115, and may have a speaker unit 111 coupled thereto. The speaker unit 111 is a device for converting an electric signal into a voice signal and outputting the voice signal. The speaker unit 111 is coupled to the inside of the upper frame 110 or to the lower surface 115 of the upper frame 110 or to the through hole H1 formed in the lower surface 115 of the upper frame 110 . The speaker unit 111 may be spaced apart from the lower surface 115 of the upper frame 110 as shown in FIG. A through hole may be formed at a position corresponding to the first through hole H1 and a speaker unit 111 may be formed in the plate. And can be located across the through-hole. In addition, the upper frame 110 may be formed with an inclined surface such that the upper surface 117 of the inner space has a larger thickness from the front surface to the rear surface. The upper frame 110 may be made of a wood material, and a log, such as a maple tree or the like, may be used, which is advantageous for vibrating sound.

With this structure, sound transmission of sound transmitted through the upper frame 110 can be maximized, and sound transmitted from the speaker unit 111 can be concentrated toward the front of the upper frame 110. 3, the sound emitted from the speaker unit 111 is divided into

open spaces

112 and 113 formed in the front surface of the upper frame 110 and a first through hole H1 formed in the lower surface 115 ). And may be transmitted from the lower side to the upper side through the through holes of the plate in the upper frame 110 and then to the outside through the open front space 112 of the upper frame 110. Although FIG. 1 shows a case where a speaker network is formed in a portion 113, the present invention is not limited to this case, and a speaker network or the like may not be coupled. The upper frame 110 may have a space open only to the front surface as shown in FIG. 1, and the rear surface and both sides may be blocked.

The intermediate frame 120 is coupled to the lower portion of the upper frame 110, and may have a hollow space 125 formed therein. The second through hole H2 and the third through hole H3 may be formed on the lower surface 121. [ Also, a sounding plate 127 may be formed in the space 125 inside the intermediate frame 120. The sounding plate 137 may be formed on the lower surface of the space 125 inside the intermediate frame 120 and may be formed at a position corresponding to the through hole H1 of the upper frame 110. [ In addition, the sounding plate 137 may have a shape that increases in height from the front direction of the intermediate frame 120 toward the back side, or decreases. For example, as shown in FIG. 2, the sounding plate 137 may have a shape that has a predetermined inclination from the front direction of the intermediate frame 120 to the backward direction, and has a height lowered and a height lowered. As shown in FIG. 2, the highest part of the sounding plate 137 may be located at the center portion of the first through-hole H1. The sounding plate 137 may be a plate for sounding sound, and may be made of a material such as maple. In addition, the intermediate frame 120 may be made of a wood material favorable for sound transmission.

The pipe 136 may have a hollow interior and both ends open. The number of pipes 136 equal to the number of the through holes H2 and H3 may be formed in the lower frame 130 and the through holes H3 may be formed in the lower frame 130, The number of pipes 136 different from the number of the through holes H2 and H3 may be formed in the lower frame 130. [ That is, at least one pipe 136 may be coupled to the lower frame 130. The pipe may be a circular alloy pipe or a pipe type copper pipe, and may be made of brass, gold, silver, chrome, or the like. The pipe 136 may be installed in the lower frame 130 between one and eight, but the number of the pipes 136 in the present invention is not limited to this case.

When a plurality of pipes 136 are coupled to the lower frame 130, the pipes 136 may have different lengths as shown in Fig. One end of each of the pipes 136 is coupled to the second through hole H2 and the other end is coupled to the fourth through hole H4 formed on the lower surface 133 of the lower frame 130, (H4). For example, the longest pipe among the pipes 136 may be coupled to the fourth through-hole H4 at the other end, and the other end may be positioned apart from the fourth through-hole H4. As the length of the pipes 136 is different, the sound is transmitted to the lower surface with a time lag and is discharged to the outside, so that a richer and larger sound can be reproduced.

A lower resonance tube (not shown) is defined between the fifth through-hole H5 and the third through-hole H3 formed on the lower surface 133 of the lower frame 130 by a partition wall in the vertical direction, 138 may be formed. For example, the lower resonance tube 138 may be formed behind the location where the pipe 136 is formed. 1 to 3, the space in which the pipe 136 is positioned and the lower resonance tube 138 can be spatially separated by dividing the inner space of the lower frame 130 through a partition wall or the like.

[ And a support 150 coupled to the lower surface of the lower frame 130 so that the lower surface of the lower frame 130 can be supported apart from the floor. The sound transmitted through the intermediate frame 120 moves downward through the pipe 136 and the lower resonance tube 138 to the lower side of the resonance modular furniture 100 having the acoustic function, It can be formed long. A part of the space thus formed can be used as the storage space 139. The storage space 139 may be separated from the lower resonance tube 138 through a partition or the like. Also, although not shown in FIGS. 1 to 3, a partition may be provided between the storage space 139 and the pipe 136 to divide the space.

3, a part of the sound generated by the speaker unit 111 is transmitted to the upper frame 110 through the opening of the upper frame 110, And the rest of the sound generated in the speaker unit 111 is transmitted through the first through holes H1 formed on the lower surface 115 of the upper frame 110 To the inside of the intermediate frame 120. [0033] FIG. Some of the sound transmitted into the intermediate frame 120 may be transmitted to the outside through the open front of the intermediate frame 120 via the sounding plate 137. [ The other part of the sound transmitted to the intermediate frame 120 passes through the sounding plate 137, the second through hole H2, the at least one pipe 136 and the fourth through hole H4, And the rest of the sound transmitted to the intermediate frame 120 is transmitted to the lower frame 130 through the sounding plate 137, the third through hole H3, the lower resonance tube 138 and the fifth through hole H5. As shown in FIG. The sound generated from the speaker unit 111 through such a path can be transmitted to the outside through the front surface and the bottom surface of the resonance modular furniture 100 having the acoustic function with a time difference.

The upper frame 110, the intermediate frame 120, and the lower frame 130 described above may be integrally formed or separated from each other. For example, when the upper frame 110, the intermediate frame 120, and the lower frame 130 are each in the form of a separable module, the upper surface of the intermediate frame 120 and the lower frame 130 are opened Can be.
