Speaker system and device rack arrangement

A speaker system and device rack arrangement including a plurality of cabinets equipped with speakers, a flat top plate mounted on the cabinets at the top, a plurality of sound absorbing cushions respectively sandwiched in between the cabinets and the flat top plate, and a carrier plate supported on the flat top plate for carrying tuner, amplifier, etc., the carrier plate having a plurality of springy cones at the bottom respectively supported on the flat top plate above each cabinet.

BACKGROUND OF THE INVENTION 
The present invention relates to audio equipment racks, and more 
particularly to such an audio equipment rack which utilizes speaker 
systems as stands for supporting a flat top plate and a carrier plate for 
carrying tuner, amplifier, etc. 
In a regular audio system, the speaker systems and the tuner are separately 
disposed. When the speaker systems are driven to produce sound, the 
cabinets of the speaker systems may be forced to vibrate. The vibration 
must be properly controlled so as not to interfere with the quality of the 
sound. There is known a resonance eliminating stand for supporting the 
cabinet of a speaker system. This structure of resonance eliminating stand 
comprises a stand body, a stand base, a conical member, and a disk. The 
conical member is a tapered rod having a flat bottom end. The disk has a 
certain thickness, a bottom side curved inwards, and a circular center 
through hole adapted for receiving the tapered tip of the conical member. 
The stand base and the stand body have a respective circular center hole 
facing each other and adapted for receiving the disk in between the stand 
base and the stand body. There is also known a shock absorbing cabinet 
stand for supporting the cabinet of a speaker system. This structure of 
shock absorbing cabinet stand comprises a top cushion, a bottom cushion, 
and a support fastened between the top cushion and the bottom cushion. The 
support has two opposite ends respectively tapered. 
The aforesaid devices are designed to reduce the resonant energy 
transmission area of the cabinet. However, because the cabinets of regular 
speaker systems are made from wooden material, gaps exist among wooden 
parts. This loose structure design tends to cause a vibration. 
SUMMARY OF THE INVENTION 
It is the main object of the present invention to provide a speaker system 
and device rack arrangement which uses speaker systems as stands of a rack 
for supporting audio equipment, permitting the cabinets of the speaker 
systems to be firmly held down by the load to eliminates the occurrence of 
vibration. It is another object of the present invention to provide a 
speaker system and device rack arrangement which combines an audio 
equipment rack and speaker systems into a rack assembly for supporting 
tuner, amplifier, or any other devices, so as less audio equipment 
installation space is needed. It is still another object of the present 
invention to provide a speaker system and device rack arrangement which 
keeps the speaker systems connected together for supporting the tuner and 
other parts of an audio equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIGS. 1, 2 and 3, a plurality of cabinets 1;1' with speakers 
10 are arranged in parallel, and fastened together by a flat top plate 2. 
The flat top plate 2 is mounted on the cabinets 1 at the top and fixedly 
secured thereto by for example screws. Porous sound absorbing cushions 3 
are respectively sandwiched in between the cabinets 1;1' and the flat top 
plate 2. The sound absorbing cushions 3 are made from soft material for 
example rubber or sponge, and adapted to prevent transmission of 
vibrations between the cabinets 1;1'. A carrier plate 4 is supported on 
the flat top plate 2 for carrying tuner 5, amplifier 6, etc. (see FIG. 3). 
The carrier plate 4 is made from rigid material that does not deform 
easily when carrying a load. A plurality of springy cones 40 are fixedly 
mounted on the carrier plate 4 at the bottom side, and respectively 
supported on the flat top plate 2 above each cabinet 1;1'. The springy 
cones 40 are preferably made from rubber. The cross section of the springy 
cones 40 reduces gradually from the carrier plate 4 toward the flat top 
plate 2, so that less vibration transmission area exists between the flat 
top plate 2 and the carrier plate 4. Because the springy cones 40 are 
respectively supported on the flat top plate 2 above each cabinet 1;1', 
the weight of the load carried on the carrier plate 4 is directly received 
by the cabinets 1;1'. 
According to the aforesaid arrangement, the cabinets 1;1' are 
simultaneously used as rack stands to support the flat top plate 2, the 
carrier plate 4 and the load carried on the carrier plate 4. Because the 
cabinets 1;1' bear a heavy burden, they are firmly retained in place 
against vibrations, and interference of resonance is eliminated.
