DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a headphone with
adjustable bass characteristics. Only small speakers can be used for headphones, but small
speakers are structurally suitable for stuttering reproduction, but they are suitable for bass
reproduction and have i ? i defects. The present invention is based on the structure of
headphones aimed at enabling good bass reproduction, which has conventionally been
considered to be difficult with small lid speakers. * An embodiment of the present invention will
be described for K11IIiK. The layer on the side of the present invention is, as shown in FIG. The
rear (left in the figure) of LJ / 2 noble K speaker 2 and the inner IIIIK guide rail 8 behind it are
provided symmetrically with the cylindrical closed chamber 3 outside the outer shell 3 'of the bill
closed chamber 3. At the end, insert the rod screw 5 with the tab 5 'on the left taK into the large
hole 4 and insert the nut & 5; The rod screw 5 is rotatably mounted in the hole 4 and from the
right end of the rod screw 5, the damper 7 having a recess 8 'symmetrically shown in FIG. 2 and
FIG. 3 is screwed in the central screw hole 7'. At the same time, the recess 8 'is engaged with the
idler 8 at the same time. Damper 7 # i Guytray # 8 Kff which is screwed into the rod screw 5 by
the screw hole 7 'in the left or right direction of the knob 5' and moves it back and forth (left and
right in ml) K The volume of the chamber closed OvM between 2 and the damper 7 is changed.
According to the above description and the present invention, the knob characteristically rotates
to the left and right to easily change the volume of the sealed chamber in contact with the back
