FIELD OF THE INVENTION The present invention relates to a headphone in which the ear pad is
improved to improve its characteristics. The configuration of the prior art and its problems In
general, the headphones are configured as shown in FIG. That is, the ear pad 5 is attached to the
front surface of the housing 4 containing the speaker unit (FIG. 2 in FIG. 3) via the hanger caps 2
and 2 'at both ends of the headband 1 made of U-shaped elastic member. ing. In such a
headphone, the conventional ear pad 6 is configured as shown in FIG. That is, in the case shown
in FIG. 2, a foamed resin having open cells, such as urethane, is bored, and the outer periphery of
the housing 4 is covered. The ear pad 5 having such a configuration is an open-type headphone
with a soft feel when listening to the headphone. However, when such an open type ear pad 6 is
worn with a sodaphone, the sound leaks to the outside and external noise enters the ear, so when
listening with headphones, it is difficult to reproduce the bass and the bass There was a
drawback that I could not hear well. That is, although the headphone using the ear pad 6 shown
in FIG. 2 is excellent in the wearing property, since the air permeability is good, when the user
wears the headphone and listens to music, it passes from the open end face of the housing 4
through the ear pad 6 Since the sound leaks to the outside, there is a disadvantage that the bass
is not reproduced as shown in the side of FIG. SUMMARY OF THE INVENTION The present
invention is intended to eliminate the above-mentioned conventional drawbacks, and it is an
object of the present invention to provide high sensitivity headphones capable of bass
reproduction. SUMMARY OF THE INVENTION In order to achieve the object, according to the
present invention, an elastic non-permeable resin member is attached to the open end face of the
housing with an adhesive, and an ear pad made of a foamed resin having air permeability on the
resin member. Is a combination of DESCRIPTION OF THE PREFERRED EMBODIMENT The
present invention will be described below with reference to FIGS. 3 to 4 showing an embodiment
of the present invention. In the embodiment shown in FIG. 3, a ring-shaped resin member 6

having elasticity but not air permeability is provided with a double-sided adhesive 7 on the side
of the housing 4 to be attached to the buckle plate. It is attached to the open end face of the
housing 4. Then, an ear pad 6 made of a hollow foamed resin having urethane-based open cells is
attached from above the resin member 6. In the headphone having such a configuration, since
the sound is less likely to leak from the open end face of the housing 4 by the elastic but non-airpermeable resin member 6, the ear feel is good, as shown in FIG. It becomes high sensitivity
headphones with improved bass reproduction.
Effects of the Invention As described above, the headphones of the present invention can be
configured as described above, can be easily heard, can enjoy excellent headphone reproduction
with improved bass reproduction sensitivity, and can be easily manufactured and cost-effective. It
is a dog of practical value that does not become a disadvantage and has a high-class appearance.
