[0014]
BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will
be described below with reference to the attached drawings.
[0015]
The loudspeaker according to the present embodiment is provided with a cylindrical voice coil 1
as shown in FIG. 1, a disc-shaped diaphragm 2 coupled to the outer center of the voice coil 1, and
the diaphragm 2 on the surface side. A disc-like cover 3 is provided.
[0016]
The voice coil 1 is composed of a cylindrical bobbin 1a and a coil 1b wound around the outer
lower portion thereof.

[0017]
The inner coil 1b portion is movably provided in a gap 17 portion between the plates 5 and 6 of
the magnetic circuit constituted by the doughnut-shaped magnet 4 and the plates 5 and 6
provided on the upper and lower sides thereof.
[0018]
Further, below the diaphragm 2 fixing portion of the bobbin 1a, the inner side of the disk-like
damper 18 is fixed, and the outer side of the damper 18 is fixed below the metal frame 7.
[0019]
The diaphragm 2 is made of resin, and is made a reflective surface by vapor-depositing metal on
its surface.
Also, in order to supply light to the surface of the diaphragm 2, four light emitting elements 8 are
provided at 90 degrees each.
[0020]
Specifically, the column 10 with the flange 10a is fitted to the upper surface opening of the
cylindrical column 9, but four light emitting elements 8 are arranged at intervals of 90 degrees in
the portion of the flange 10a. It is arranged.
[0021]
Moreover, the disk-shaped cap 11 which the center protruded upward using the flange 10a part
is being fixed.
[0022]
The cap 11 is made of resin, and metal is vapor-deposited on both the front and back surfaces to
form a reflective surface.
[0023]
Therefore, the light of the light emitting element 8 is reflected directly or at the back surface side

of the cap 11 to reach the reflecting surface of the surface of the diaphragm 2 and then travels
forward to the viewer side through the pores of the cover 3 It will be.
[0024]
It is a dustproof cover 12 that extends from the flange 10a toward the diaphragm 2 and is made
of urethane foam.
[0025]
Reference numeral 13 denotes an electronic device main body, in which the metal frame 7 is
fixed by screws 14.
[0026]
In the above-described configuration, the cover 3 is formed of a black-colored porous body.
Specifically, for example, a metal plate is punched into a porous shape and then a black-colored
painted or a black-colored resin is formed.
That is, by making the cover 3 a black porous body in this manner, the reflected light of the light
emitting element 8 from the reflection surface of the diaphragm 2 surface is effectively
confirmed from the surface of the cover 3 through the pores of the cover 3 This can enhance the
viewing effect.
[0027]
In other words, when the cover 3 is white, light from the outside (viewer side) of the cover 3 is
reflected by the cover 3 and reaches much to the viewer side, whereas the cover 3 is as in the
present embodiment. If the black color is used, the light reflected from the reflection surface of
the diaphragm will be more noticeable as the reflection from the cover 3 is reduced, and
furthermore, if the cover 3 through which the reflected light passes is a black porous body For
example, since the portion through which the reflected light passes is blackish, the reflected light
becomes clearer, and as a result, the viewing effect is enhanced as described above.
[0028]
Further, in the present embodiment, the rear surface portion of the cover 3 inward from the
outer peripheral end of the diaphragm 2 is supported on one end side of the edge 15.

[0029]
In this manner, by supporting the inward portion of the edge 15 on the back surface of the
diaphragm 2 and further on the outer periphery, the reflection surface of the reflection plate 2
can be widely used without being partially covered by the edge 15 As a result, the reflective
surface can widely enhance the viewing effect.
[0030]
Further, in the present embodiment, a doughnut-shaped frame 16 made of paper or resin is
provided on the outside of the diaphragm 2, and between the frame 16 and the outer peripheral
end of the diaphragm 2, it is sunk on the back surface side of the diaphragm 2. The other end of
the edge 15 is fixed to the frame 16 through the portion.
[0031]
For this reason, since the groove 2A to the back surface side of the diaphragm 2 is formed
between the outer peripheral end of the diaphragm 2 and the frame 16, the viewing effect is
enhanced.
[0032]
That is, if the groove 2A is formed at the outer peripheral end of the diaphragm 2, the diaphragm
2 and the frame 16 are completely separated by the groove 2A, that is, the outline of the
reflected light from the reflection surface of the diaphragm 2 appears clearly. Thus, the viewing
effect is enhanced.
[0033]
Further, according to the present embodiment, the edge 15 is blackish, and if the edge 15 is
blackish, the inside of the groove 2A becomes darker black, and the outline of the reflected light
from the reflection surface of the diaphragm 2 becomes clearer. It will appear and this will
enhance the viewing effect.
[0034]
Furthermore, in the present embodiment, the frame 16 is black, and if the frame 16 is black,
optical separation from the reflection surface of the diaphragm 2 can be easily achieved, thereby
enhancing the viewing effect.

[0035]
Further, since the light emitting element 8 of the speaker shown in FIG. 1 is made to emit light by
a signal correlated with the signal to the coil 1 b of the voice coil 1, reflected light correlated with
the sound from the surface reflection surface of the diaphragm 2 of the speaker By being
emitted, the viewing effect as an electronic device can be enhanced.
[0036]
As described above, the present invention comprises a voice coil, a diaphragm coupled to the
voice coil, and a cover provided on the surface side of the diaphragm, the surface of the
diaphragm being a reflecting surface In addition to providing a light emitting element for
supplying light to the surface of the diaphragm, the cover is formed of a black-based porous
body, and the cover is a black-based porous body, whereby the diaphragm surface is provided.
The reflected light of the light emitting element from the reflecting surface of the light source
can be effectively confirmed from the cover surface side through the hole of the cover, whereby
the viewing effect is enhanced.
[0037]
In other words, when the cover is white, light from the outside (viewer side) of the cover is
reflected by the cover and reaches the viewer side much, whereas when the cover is black, the
cover As the reflection decreases, the light reflected from the reflection surface of the diaphragm
tends to be noticeable. In addition, if the cover through which the reflected light passes is a black
porous body, the portion through which the reflected light passes is black. Being a system, the
reflected light becomes clearer, and as a result, the viewing effect is enhanced as described
above.
