DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker
apparatus having an optical display function such as a light emitting diode. And a kind of speaker
device! ! 1 and 2 show. In the figure, 1 is a cabinet, 2 is a sound quality core 1 ░, and is a
speaker panel, 3 is a light emitting diode, 4 is a high sound speaker unit, 5 is a medium sound A
speaker unit 6 is a bass speaker unit. The light emitting diode 3 is attached to the Sazono funnel
2 and connected to an input terminal 7 as shown in FIG. 2. 8 is for frequency band division A
network circuit, 9 is a resistor, and 10 is a diode. The resistor 9 is for K to prevent the current
more than the maximum allowable forward current of the light emitting diode 3 from flowing
even by the assumed maximum input voltage, and the diode 10 prevents the light emitting diode
3 from an excessive reverse voltage. It is a book for protection ? If the value of the resistance 9
is selected according to the maximum allowable input of the speaker device in the above device,
the current flows to the light emitting diode 3 according to the signal voltage applied to the input
terminal 7 It is an extreme value, and most of the input is transmitted to the network circuit 8,
divided into frequency bands and converted into acoustic energy in each speaker device 4.5.6.
Thus, at normal input, the light intensity of the light emitting diode 3 is small, and as the input 2
and power become closer to the maximum allowable input, the light intensity becomes thicker.
That is, it becomes an alarm for an excessive input of the speaker device. As described above,
although the light emitting diode 3 works as an alarm display element for an excessive input, the
light emitting part of the light emitting diode is usually 5- or less, and if it is attached to the
subchannel 4 arranged at one corner of the front face of the cabinet 1 If special attention is not
paid when the speaker device is operated, the luminous intensity may be lowered to reduce
power consumption, and the alarm display for excessive input due to the light emission of the
light emitting diode 1 may be missed. The present invention has been made to eliminate the
above-mentioned drawbacks. The purpose of the present invention is to provide a speaker device
capable of effective light emission display by attaching a light emitting diode to a diaphragm
which is easy to draw attention. The following idea will be described in detail based on the
illustrated embodiments. FIG. 3 shows an embodiment of the present invention, and it is a coneshaped diaphragm consisting of an 11 ? honeycomb structure. A honeycomb structure which is
a material of this diaphragm 11 is shown in FIG. As shown in FIG. 5, the core material 23 is
sandwiched between two skin materials 21 and 22. A large number of cell-like spaces 24 are
formed by the skin materials 21 and 22 and the core material 23.
A part of the skin material 22 on the back surface side of the diaphragm 11 is removed, and the
light emitting diode 3 is fixed to the light emitting diode storage portion where the light emitting
diode 3 is stored in the cell space 24 of that portion In order to compensate for the strength
reduction due to partial removal of the material, epoxy resin or the like is filled. In the light
emitting diode P3, the lead wire 3a is connected to the copper wire 13 for connecting with the
external circuit on the relay terminal 12. Further, the copper wire 15 is connected to the relay
terminal 14, This is connected to the lead wire of an I-shaped coil (not shown) joined to the
central portion 11 a of the cone-shaped diaphragm 11. The skin material 21 on the surface side
of the honeycomb structure constituting the diaphragm 11 is used so that at least the storage
portion of the light emitting diode 3 becomes translucent. In the speaker device having the above
configuration, a honeycomb structure is used as the diaphragm 11 of the speaker unit, and the
light emitting diode 3 is accommodated in the cell-like space formed by the skin material and the
core material. The diaphragm 111C, which is easy to stick to, is located at K, and if an alarm
display for an excessive input is made by the light emission of the light emitting diode 3, accurate
visual recognition is possible. Although only the light emitting diode 3 is attached to the
diaphragm 11 in the above embodiment, when displaying the input of the speaker unit itself to
which the light emitting diode is attached, or the speaker unit is for the entire band and only one
speaker device In the case of using it, for example, the resistor 9 shown in FIG. An accessory
circuit component such as a diode 10 may be attached to the diaphragm 11 as well. In this case,
a signal can be supplied to the display circuit from the relay terminal 14 for the discoil, and the
relay terminal 12 and the copper wire 13 can be omitted. Also, the number of light emitting
diodes is limited to one. : Here, as shown in FIG. 5, a plurality of series circuits in which
resistances 9a, 9b... Are connected in series to a plurality of light emitting diodes 3a, 3b. It is also
possible to change the number of light emissions according to the input voltage by connecting in
parallel and connecting this to the input terminal 7 via the diode 17. In this case, the light
emitting diodes aa, 3b,..., The resistors 9a, 9b,. The connection with the resistor 16 is made by the
copper wire 13. Furthermore, it is also possible to geometrically arrange a plurality of light
emitting diodes and to turn on another power source, so that it is possible to realize a speaker
device decorated with beautiful illumination.
As described above, according to this invention, since the light emitting diode is directly attached
to the honeycomb diaphragm and the diaphragm has a display function, effective light emission
display is possible even with a small light emitting diode. 0
