DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker cabinet,
and more particularly to a speaker cabinet having a horn baffle. The sound wave from the back
of the speaker becomes sound pressure to vibrate the baffle attached to the speaker. In a cabinet
in which the horn-full is mounted on a baffle with a speaker, such vibration propagates to the
horn baffle and the reproduced sound is adversely affected by this. SUMMARY OF THE
INVENTION The object of the present invention is to provide a loudspeaker cabinet with a horn
baffle which eliminates the above-mentioned unwanted effects. The invention will now be
described with reference to the embodiments shown in the drawings. The drawings show a
speaker cabinet with horn baffles in connection with the present invention. A cone-shaped
speaker 3 is attached to a first baffle 2 which is a front surface of the speaker cabinet 1. A second
baffle 4 having a reproduced sound radiation hole 5 is disposed on the front surface of the first
baffle 2. The baffle 4 is bent inwardly around the radiation hole 5 to form a horn baffle.
Reference numeral 6 denotes a vibration isolation member which connects the inner end portion
of the horn and the first baffle 2 and is added to the first baffle 2 around the vicinity of the
speaker 3. The outer periphery of the horn baffle 4 is bent inward as shown, and extends parallel
to both side surfaces 8 and 9 of the cabinet 1 and the top surface 10. The outer end 12 facing
the bottom surface 11 of the horn baffle 4 abuts on the bottom wall 11 constituting the bottom
surface, and forms an approximately flush surface with the bottom surface. The three spaces A, B
and C respectively defined by the extensions a, b and C of the horn baffle 4 and both side walls 8
and 9 and the top surface 10 are respectively anti-vibration member adding members 20 'and 20
#. And 24 to constitute sound absorbing chambers A, B and C. Similarly, the sound absorbing
chamber is provided by the horn baffle 4 and the first baffle 2 and the vibration damping
members 6, 24, 20 "and f +, and the horn baffle 4. A sound absorbing room E is formed by the
first baffle 2 and the vibration isolating member 6 and the additional members 1 and 26. It is
preferred that the positions of the vibration-proof member holes', '', '', '' 2tll ?and 24 be the side
edges of both side faces 8, 9 and the top face lO. Although not shown, it is preferable to further
extend the end of the second baffle to form a sound absorbing chamber on the bottom and back
of the cabinet 1 as well. It should be noted that the opening of the horn can be selected as
appropriate, and neither is stated. As described in the present invention, since the horn / full is
attached to the baffle having the speaker via the vibration isolation member, the vibration
propagation from the bubble having the speaker to the horn baffle is It has the excellent effect of
being blocked, so that a further improvement of the reproduced sound is achieved.
