BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a speaker according to
the present invention, FIG. 1 is a half sectional view of the speaker, and FIG. 2 is an operation
view showing a coupling structure of a driver unit and a cover. . Guide groove comprising an inlet

vibration 11 (1)-plate, sufficient fixation can not be performed and 1 * low resonance same wave
number becomes unstable, and assembling is also difficult. In order to eliminate the abovementioned conventional drawbacks, the following description will be made with reference to FIG.
1 and FIG. 111 is a horn to be taken from a synthetic resin, and in the i city of the horn Ill, a

addition, the horn round ribbon 1f3i [is a cover which loses from a synthetic resin having a
barbed circular wedge shape (71 is externally fitted and fixed, the cover in the fixed form fg (71

traveling in the direction of an oblique spiral from the entrance (9 a) And a recess (9C) in the
direction of the axis JC>. It is to be noted that the guide rod (9) may be provided on the inner
surface of the cover (7) and the horn cylinder (31) on the inner surface of the cover (7) to the
projecting pole in reverse to the above. As for the assembly of the speaker with the above
configuration, a horn circle N [lff 1131K, a voice coil l 1 lt, a dome-shaped vibration lll lj plate

coupled according to the present invention, they can be easily disassembled or non-electrically
assembled, and the characteristics can be stabilized in the nest, which is practically effective. 4
