本発明はセラミック圧電素子を用いた複合型スピーカに
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite speaker using a ceramic piezoelectric element.
従来、セラミック圧電素子を用いたスピーカは１つの圧
電素子に対して１つの振動板が組み合わせられていたが
、１つの振動板で広帯域の周波教範′囲を再生するのは
困難であった。Conventionally, speakers using ceramic piezoelectric elements have combined one piezoelectric element with one diaphragm, but it has been difficult to reproduce a wide frequency range with one diaphragm.
本発明は、このような従来のスピーカの欠点を除去する
ために、口径の小さい振動板で再生周波数の高い部分を
受は持たせ、口径の大きい振動板で再生周波数の低い部
分を受は持たせ総合的な再生周波数帯域を広げたことを
特徴とする。In order to eliminate these drawbacks of conventional speakers, the present invention uses a diaphragm with a small diameter to carry the high reproduction frequency part, and a large diameter diaphragm to carry the part with low reproduction frequency. It is characterized by widening the overall reproduction frequency band.

充てんきれている。A ceramic piezoelectric element 2 is held at the bottom of a speaker frame 1, and a large diameter diaphragm 3 and a small diameter diaphragm 4 are adhered to the ceramic piezoelectric element 2. The edge part of the large diameter diaphragm 3 is supported by the frame 1, and the small diameter diaphragm 4
The edge portion of is supported by the equalizer small diameter diaphragm holding part 5. The space between the edge portions of the large-diameter diaphragm 3 and the small-diameter diaphragm 4 is filled with an airtight agent 6 such as edge paint.
本発明はり上のように同一セラミック圧電素子に口径の
