Description
【考案の詳細な説明】
本考案は圧電素子を用いたスピーカに関するもので〜圧
電素子へ接着剤により固定する振動板の固定方法に工夫
を加えることにより、圧電素子への固定場所が中心から
ずれた場合でも音圧周波数特性のばらつきを小さくする
ことを目的とする。[Detailed description of the invention] This invention relates to a speaker using a piezoelectric element. By adding a new method to the fixing method of the diaphragm, which is fixed to the piezoelectric element with adhesive, the place where it is fixed to the piezoelectric element is shifted from the center. The objective is to reduce the variation in sound pressure frequency characteristics even when
従来、振動板と圧電素子との接合部分の形状は丸形であ
ったため、圧電素子への接合場所が中心からずれると音
圧周波数特性にばらつきが生じ＼安定した特性が得られ
ないものであった。Conventionally, the shape of the joint between the diaphragm and the piezoelectric element was round, so if the joint location to the piezoelectric element was shifted from the center, the sound pressure frequency characteristics would vary and stable characteristics could not be obtained. Ta.
すなわら、安定した音圧周波数特性を得るためには振動
板を圧電素子の中心部に精度よく貼りつげることが非常
に重要である。In other words, in order to obtain stable sound pressure frequency characteristics, it is very important to accurately attach the diaphragm to the center of the piezoelectric element.
本考案は接合部分が丸形では、接合場所がわずかにずれ
ても音圧周波数特性もそれに比例してばらつくことに鑑
みて、接合場所の形状を長円形あるいは多角形状にして
、ばらつきを小さくしたものである。In this invention, if the joining part is round, even if the joining location is slightly shifted, the sound pressure frequency characteristics will vary proportionally.In this invention, the shape of the joining location is made oval or polygonal to reduce the variation. It is something.
第１図〜第３図はその一実施例を示すもので、図中、１
は振動板、２は圧電素子であり、この両者の接合部分Ａ
の形状を長円形としている。Figures 1 to 3 show one example of this.
is a diaphragm, 2 is a piezoelectric element, and the joint part A between the two is
The shape is oval.
したがって、長円の長径ａ方向に振動板１が相対的にず
れたとしても、長円形状により補償することができ、高
圧周波数特性のばらつきを従来にくらべて小さくするこ
とができる。Therefore, even if the diaphragm 1 is relatively shifted in the direction of the long axis a of the ellipse, it can be compensated for by the ellipse shape, and variations in high voltage frequency characteristics can be made smaller than in the past.
なお、接合部分Ａの形状は長円形状に限らず、多角形状
でもよ０゜なお、第３図においてｂは短かい方の径を示
す。Note that the shape of the joint portion A is not limited to an elliptical shape, but may be a polygonal shape. In FIG. 3, b indicates the shorter diameter.
以上説明したように本考案によれば圧電素子への振動板

り、特に量産時におげろ音圧周波数％性の安定化がはか
れる。As explained above, according to the present invention, by forming the joining portion of the diaphragm to the piezoelectric element into an elliptical or polygonal shape, it is possible to stabilize the sound pressure frequency percentage, especially during mass production.
