DESCRIPTION JPS55155185
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an end view of a conventional speaker, FIG. 2
is a cross-sectional view showing one embodiment of the speaker according to the present
invention, and FIG. 3 is another embodiment of the present invention. FIG. 1: Frame, 2:
Diaphragm, 3: Edge, 4: Inner peripheral edge, 5: Outer peripheral edge.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker in
which the unnecessary emission of sound from the edge is eliminated at the edge, which is the
periphery of the speaker diaphragm, as shown in the prior art 1143, the frame of the speaker.
There was an end date between 1 and the moving plate owner. Ezushishi Urethane Ar- is a
dough-shaped one molded with a cloth, which is fixed to the inner peripheral end of the frame 1
and adhered to the outer periphery of the vibrating smile. However, this conventional product is
an edge that becomes a pair with the diaphragm! Unwanted vibration noise is emitted fromwhich affects the speaker frequency characteristic by t-4. In the case of viscous agent 會 applied
1, squashed □ '4 "-/ / i −-· · · · · · · · · · · · · · · · · · · · in the air dust and other foreign matter adhere
to the speaker performance of the initial design value Unlike in the past, there are many cases.
The present invention overcomes the above-mentioned drawback V. FIG. 2 is a sectional view
showing an embodiment of the present invention. In FIG. 2, the edge wedge is fixed slightly
outside of the inner peripheral edge 4 of the frame 1 and bonded slightly inside of the outer
peripheral edge 5 of the diaphragm. Is the structure in which the gap a becomes as narrow as
possible as far as the inner peripheral ridge of the frame 1 and the outer peripheral end 5 of the
diaphragm 2? Have. In this case, the radiation of the sound of the enju which became a pair with
the pregnant woman's moving plate is narrow while the inner periphery of the frame 1 and the
outer periphery of the vibrating plate + 4 # i5! It decreases to pass through iik and emits almost
no sound to the front of the speaker. Next, FIG. 3 is a cross-sectional view of a structure showing
an embodiment of the invention in a flat panel speaker. Since the operation in FIG. 3 is
completely the same as FIG. 2, the detailed description is omitted. According to the present

1
invention, the above-mentioned bare c has no effect on the frequency characteristics of the
loudspeaker and does not radiate unnecessary sound from the next edge part 2 pave b '' 'and' 17. At the same time, there are many advantages, such as the ability to eliminate factors such as
changes in edges due to external influences.
