DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker
apparatus used together with an axial moving part such as a volume attenuator and a switch, and
the operating shaft of the axial staring part attached to the back of the speaker is provided in a
septa hole of 17 bekers. C Struct to the front of the cone through the through hole and attach the
sway to which the sound 1 ffilf M is ported to this splay to effectively utilize the air gap in front
of the cone to improve sound volume diffusivity, sound quality, etc. , From the speaker i + IIo, to
simplify the wiring of the device further 72/1 no, l ? ? ?; sewing machine; depression 2.8 's. In
general, in the speaker apparatus using the speaker sound m-node, switch, etc., the 171b river
part, or-node part is installed at a different place from the speaker, and a space is required for
mounting the product- There is a drawback that the cost is too complicated. In addition, since a
cone speaker generally used is a direct radiation type as compared to a horn type speaker, its
efficiency is poor, and the adjustment of directivity is also difficult. Furthermore, since the air
vibration by the diaphragm e collides and interferes at the center in front of the cone, it suffers
from sonoelectricity compared to the flat plate type diaphragm, and this invention solves the
above-mentioned drawbacks and this is not To explain the roadside, hold the Linogue Mag 4
between the lower plate 2 and the ring-shaped upper plate 8 formed in the center holes 1 and -k,
and in the gap between the inner periphery of the upper plate 8 and the center ball lIll. , A
through hole 7 is provided in the above-mentioned setter hole l of the known cone speaker in
which the ^ -bi / g coil 6 integral with the cord 15 is interposed, and the printed board 8, 1bialti
product 9 etc. is provided. , ? L) S ? ? ? ? и Attached to the lower plate 2 of 8 and use the

physician obtained by dividing the operating shaft 12 is fixed to Chakuzurutsukasa off by stop
screws. This neck compensation device and operation knob 12 wants to compensate the sound 1
output of the speaker and the shape of the cone 5! # @ Depending on characteristics, directivity,
diffusivity, sound resources, etc., its shape, thick и 5 years old, overly selected material used 11, r:
J, -1i Example is along the curved surface of cone 5 When made conical, the Qz 'sound spreads
radially and the service area is expanded. Also, if the material is a porous material, it becomes
another ship such as a phase to align the phases of the emitted sound waves, so that the phase
interference between the sound waves is prevented, the frequency @ characteristic is improved,
and the sound quality is improved. In addition, since the sound waves radiated from the edges of
the cone diaphragm do not have a phase shift as in the case of the flat plate, they interfere with
each other at the center #IklIlL of the cone in the short wavelength ^ range, and the chest wave
number characteristics 1 mm becomes steep, but association mmm ? ? ? ? ? ? ? ? ? ?
? ? ? ? ? 41 41 41 41 41 41 41 41 41 41 41 41; The waves emitted from each point of the
plate are diffused in all directions smoothly along the curved surface of the compensator without
being scattered in the center, and according to the convulsions formed by the ca 76 and the
pregnancy 912, If you spread Nayori gradually, it will improve the radiation 1 as well as small.
In this way, 1 m of sound volume control knob is used by over-selecting the shape, thickness,
material, etc., and it is better to use the sound card at the same time. As the speaker, etc., each
speaker can be simply made in large numbers, and the wiring etc. can be simplified.
