例では光源の大きさが支持体により制限を受け、
十分な明るさが得られない等の欠点があつた。 As shown in FIG. 1, a light-emitting speaker conventionally used in a car stereo or the like has a light source 7 such as a light-emitting diode installed in front of a vibration system 10 with a high reflectance via a support 8, and the light beam from the light source is 9 was reflected by a diaphragm to emit light. Alternatively, there are devices that illuminate the speaker surface with a light source placed around the speaker, but in either case, the reflected light gives the illusion of emitting light, so the diaphragm and dust cap act like a curved mirror and the light is not evenly distributed. In the example shown in Figure 1, the size of the light source is limited by the support.
There were drawbacks such as insufficient brightness.

うにした発光スピーカに関する。 This invention relates to a light-emitting speaker that uses a diaphragm made of a transparent material with a semi-transparent thin film, and in which the speaker itself emits light from a light source installed behind the diaphragm.

厚さは数Å〜数千Åが適当である。 The diaphragm 1 and the dust cap 2 are made of a translucent material such as polypropylene, polycarbonate, polyester, or acrylic, and their surfaces are coated with a thin layer of metal such as aluminum or silver to form a semi-transparent thin film. Constructed to be semi-transparent. The metal coating is obtained by vapor deposition or electroless plating, and the thickness of the coating is suitably from several angstroms to several thousand angstroms.

It is installed by.

ものでもよいことは云うまでもない。 In the light-emitting speaker configured in this way, when the light sources 7, 7',... The back of the car is not visible, which prevents an unsightly appearance. When the light sources 7, 7' are turned on, the light beam 9 from the light sources passes through the diaphragm and the dust cap and is emitted in front of the speaker, making it appear as if the speaker itself is emitting light. Moreover, unlike the conventional example, there is no such thing as a light source support on the front surface that impairs the appearance, and the real image of the light source can be seen, resulting in an excellent design. Furthermore, since there are no restrictions on the space for installing the light source or the support structure, a large and powerful light source can be used, and it has the advantage that it can also be used as a light source for the outside. In the embodiment shown in FIG. 2, an annular discharge tube is used as the light source 7, and a light emitting diode is used as the light source 7', but it goes without saying that a single light source or a plurality of light sources such as ordinary incandescent lamps may be used. do not have.

ーカに関するものである。 As described above, the present invention has a diaphragm made of a transparent material with a semi-transparent thin film and a light source installed behind the dust cap, so that when the light source is turned off, the back of the speaker cannot be seen from the front. When turned on, the light passes through the diaphragm and dust cap and is emitted in front of the speaker, making it an excellent light source in terms of appearance and brightness when used in car stereos, radio cassette tape recorders, etc. It is related to speakers.
