BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view showing an example according to
the present invention. FIG. 1 is a perspective view of a small radio and is an enlarged crosssectional view taken along line X-X of FIG. I assume.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the antenna of a
small radio receiver such as a small or watch-type radio receiver. A conventional small radio
receiver, such as a portable transistor radio receiver, can not be used in a crowded place,
especially in a train, etc., and a watch type radio receiver can not be used. The performance
sometimes decreased until the antenna was inserted. In order to obtain information by using
earphones in a piezoelectric car, the present invention seeks to eliminate the disadvantages of
the upper strap. Also, a three-terminal plug type of earphone terminals and antenna terminals
and an antenna terminal plug division type such as ri shown in 1-t2-1 / IIψ2 are also 呵.
Hereinafter, an embodiment will be described with reference to the drawings. A wire earphone is
formed which leads to the earphone plug 7 through the earphone cord B having a proper length
of the core wire 6A6Nt connected to the earphone main body 5 to be I11. Conductive metal and
flexible antenna element wire 2 not flexible with synthetic resin such as vinyl chloride. The lead
wire 3 whose length is matched with the earphone cord is configured,-connected to the antenna
terminal 4, and made an antenna A. @ ー ー ー ー ド を 3 、 イ ヤ ー コ ー ド ー ド 曇 ー ド (成
す 定 と 成 形成 す る The antenna becomes a free end 1 at an appropriate place below the
earphone main body 5. Because of this configuration, when using the rC1 wire earphone of the
present invention, a lot antenna is unnecessary. Therefore, the reception in the crowded area is
practically possible. There is no problem even with phrases and micro radios.
