2. Description of the Related Art The technique of mounting a speaker in a cabinet has been well known and used since ancient times. The most common are fully enclosed and partially enclosed cabinets. Its common purpose is to utilize the resonance of sound waves to enhance the characteristics of high and low tones. However,
Traditional cabinets all have a single design, i.e. all cabinets are a single solid body, so that their resonant space has the drawback of being completely fixed and immutable. On the other hand, traditional cabinets are all fixed in size, so if you want to change the installation height, you need the help of other hardware, but even if you change the installation height, the original resonance space Couldn't change. Therefore, it was not possible to enhance the resonance effect or enhance the bass characteristic.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to enhance the bass characteristics of a speaker and increase the resonance space of the speaker to obtain excellent sound. Next, it is an object of the present invention to increase the resonance space of the speaker and not to take the volume during transportation or storage.
Another object of the present invention is to make it possible to arbitrarily change the height of the speaker mounting and increase the resonance space of the speaker to obtain the best bass characteristics.

[0004]

The speaker set of the present invention has the following structure. That is, in at least two box-shaped cabinets whose internal volume increases in sequence,
Install speakers to the one with the smallest internal volume and house each cabinet in order from the one with the smallest internal volume to the one with the largest internal volume, or stack each cabinet in order from the largest to the smallest and form one tower. The interior of the tower-shaped cabinets is connected to the bottom or the eccentric position of the vertical box wall, and the sound emitted from the back of the speaker is transmitted to all the cabinets through the through holes to improve the bass characteristics of the speaker. At least one through hole for reinforcement is provided.

The bottom of each cabinet is provided with a protrusion extending outward in the horizontal direction, the cabinet having the smallest internal volume has only one through hole, and the other cabinets have the above-mentioned through holes. A box having an opening and one opening for accommodating the above-mentioned protruding portion of the cabinet having the second smallest internal volume when accommodating the cabinet having the second smallest internal volume or stacking the cabinets in a tower shape.

[0006]

According to the present invention, at least two cabinets are provided, the internal volumes of these cabinets are sequentially increased, and any one cabinet can accommodate another cabinet having the next largest internal volume. It can be stacked in order from small to small to form a tower-shaped cabinet in which one internal volume communicates, which not only increases the resonance space of the cabinet but also by installing a speaker in the smallest internal volume. You can install the speaker at the best altitude,
This can increase the resonance effect and bass characteristics of the speaker.

In addition, in the speaker set of the present invention, when carrying or storing, a small cabinet can be housed in a large one in order, and the whole can be finally housed in a cabinet having a maximum internal volume, so that the whole volume can be reduced. Not only is it convenient, but it also prevents damage to the speaker due to impact.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, the present invention is provided with at least two box-shaped first cabinets 1 and second cabinets 2 each having an increasing inner volume, of which the first cabinet 1 having the smallest inner volume. Install the speaker 3 in the cabinet 1. No speaker is attached to the second cabinet 2 having a larger internal volume.

The first cabinet 1 described above has a bottom portion 10,
A box body having four vertical box walls 11 and a top 12,
Among them, the bottom portion 10 is provided with a through hole 13 for transmitting the sound in the cabinet, and a protrusion portion 100 extending horizontally outward is formed on the periphery of the bottom portion 10. The second cabinet 2, which has a relatively large internal volume, has twenty bottom parts,
A box body having four vertical box walls 21 is provided, and one opening 22 for placing the vertical box wall 11 of the above-mentioned first cabinet 1 from there is provided at the top end thereof (see FIG. 4). Similarly, when two or more second cabinets 2 ', 2 "having the same type and increasing in internal volume are provided, they are housed in the second cabinet 2" having the maximum internal volume as shown in FIG. It is possible. As a result, the volume of the entire cabinet can be reduced during storage or transportation, which is convenient.

Further, as shown in FIGS. 2 and 3, the second cabinet 2 provided with the above-mentioned opening 22 has an inner diameter at the inner edge of the opening 22 which is slightly larger than the inner diameter of the opening 22 and has a step-like shape, and an inner volume of A support portion 220 capable of supporting the large protrusion 100 of the first cabinet 1 is provided. With this, when a plurality of cabinets are provided, they can be stacked in order from the one having the largest internal volume from the bottom to the top to form a tower shape, whereby the height of the first cabinet 1 provided with the speaker 3 is set to the best position. This allows the best audio effect to be obtained. Of course, in order to prevent sound leakage, it is desirable to add a gasket or a sound absorbing material to the support portion 220 to increase the degree of tightness, so that sound can be prevented from leaking out and affecting the resonance effect.

As shown in FIG. 5, the cabinet 1,
When stacking 2, 2 ', 2 "from the largest to the smallest in order from the bottom to form a tower, the inner volume of each of the bottoms 20, 20', 20" of the cabinets 2, 2 ', 2 "is set to the above. At least one through hole 23, 23 ', 23 "communicating with each other is provided, so that the sound emitted from the back of the speaker 3 can be transmitted through the through holes 13, 2'.
