ある。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a flat speaker with a screen function according to the present invention, and FIG. 2 is a perspective view showing the back side thereof.
この平面スピーカは、横寸法が縦寸法よりも長くなった
矩形状をなす振動板１と、振動板ｌの裏面側に複数埋設
（又は貼着）した圧電発音体２・・・ （図示例では５
個）と、振動板１の表面側に貼着したスクリーン材３と
を備えている。This flat speaker includes a rectangular diaphragm 1 whose horizontal dimension is longer than its vertical dimension, and a plurality of piezoelectric sounding bodies 2 embedded (or attached) on the back side of the diaphragm 1 (in the illustrated example). 5
1) and a screen material 3 attached to the front surface of the diaphragm 1.
振動板１は、発泡スチロール又は発泡ポリエチレン等か
らなる２枚の発泡樹脂板を突き合わせ状に貼着してなり
、これらの発泡樹脂板間に圧電発音体２が挟着保持され
る。The diaphragm 1 is made up of two foamed resin plates made of foamed polystyrene, foamed polyethylene, etc. that are stuck together in a butt-like manner, and the piezoelectric sounding body 2 is sandwiched and held between these foamed resin plates.
圧電発音体２は、例えばＰＺＴ等の圧電セラミックから

と、これらが振動板ｌを駆動し、振動板ｌの前面側より
音声が発せられることになる。The piezoelectric sounding body 2 is made of a pair of discs made of piezoelectric ceramic such as PZT, and a metal disk with a larger diameter is concentrically attached between the two, and each piezoelectric sounding body 2 is connected to a lead wire. It is connected to an amplifier (not shown) via 4. In this way, when a predetermined electric signal is applied from the amplifier to each piezoelectric sounding body 2..., these drive the diaphragm 1, and sound is emitted from the front side of the diaphragm 1.
なお、圧電発音体２の個数については図示例の個数に限
定されるものではなく、スクリーンとして使用できるだ
けの面積を有する振動板１を実質的に駆動できる個数で
あればよい。Note that the number of piezoelectric sounding bodies 2 is not limited to the number shown in the illustrated example, but may be any number that can substantially drive the diaphragm 1 having an area large enough to be used as a screen.
スクリーン材３の材質としては、シルク布或いは白色の
薄紙が好ましく、例えば接着剤を用いて振動板１の前面
に貼着される。The screen material 3 is preferably made of silk cloth or white thin paper, and is adhered to the front surface of the diaphragm 1 using an adhesive, for example.

、この平面スピーカはスクリーン機能を併せ持つのであ
る。In the flat speaker having such a configuration, when an image is projected from the projector 5 onto the screen material 3 and the piezoelectric sounding body 2 is driven in synchronization with this, a sound corresponding to the image is emitted from the screen material 3 attached to the diaphragm 1. It will be issued. In other words, this flat speaker also has a screen function.
なお、上記実施例において、圧電発音体２の代わりに薄

ロジェクタのスクリーンとしても同様に適用できる。Furthermore, in the above embodiment, a case was explained in which an image is projected from the projector 5 onto the screen material 3 and a movie is shown.
The flat speaker of the present invention can be similarly applied as a screen for slide photographs and over-the-top projectors.

リーンが音声と映像との発生源となるので、視聴者に満
足のいく臨場感を与えることができる。According to the present invention as described above, it is possible to realize a flat speaker with a thin wall and a large area screen function in which the speaker and the screen are integrated. Therefore, since the screen becomes the source of audio and video, it is possible to give the viewer a satisfying sense of realism.

、映画鑑賞会、展示会等を開催する場合に特に有効とな
る。Furthermore, since the speakers and the screen are integrated, the configuration of the entire projection equipment can be made compact, resulting in a reduction in installation space and labor savings in transportation and setting work. Therefore, it is particularly effective when holding movie performances, movie viewing parties, exhibitions, etc. outdoors.
更に、スクリーンを兼用する振動板を軽量の発泡樹脂板
で構成するので、壁掛はスクリーンとして利用できると
いう利点もある。Furthermore, since the diaphragm that also serves as a screen is constructed from a lightweight foamed resin plate, there is also the advantage that the wall-mounted device can be used as a screen.
