Description
【考案の詳細な説明】
本考案は、小さな入力信号でも大きな音圧をもつ圧電ブ
ザーを提供することを目的とする。[Detailed Description of the Invention] An object of the present invention is to provide a piezoelectric buzzer that has a large sound pressure even with a small input signal.
一般に、第１図イ，口に示すように金属製または樹脂製

た構造をもつ圧電ブザーを使用し、高い音圧を得ようと
した時、第２図に示すように振動板１の周辺を共鳴箱３
内に固定し、大きな入力信号を必要としている。In general, as shown in Fig. 1, a piezoelectric buzzer is used, which has a structure in which a piezoelectric ceramic element 2 is bonded to a diaphragm 1 made of metal or resin using an adhesive, etc., in order to obtain a high sound pressure. When this happens, the resonance box 3 is placed around the diaphragm 1 as shown in Figure 2.
Fixed inside and requires a large input signal.
本考案は上記のような点に鑑みて創案されたものであり
、小さな入力信号で大きな音圧特性をもつ圧電ブザーを
提供することを目的とする。The present invention has been devised in view of the above points, and an object of the present invention is to provide a piezoelectric buzzer that has large sound pressure characteristics with a small input signal.
以下、本考案の一実施例について第３図イ，口とともに
説明する。Hereinafter, one embodiment of the present invention will be described with reference to FIG.
第３図イ，口に示すように本考案の圧電ブザーは、圧電
磁器素子４を貼り合せする部分に多孔の空孔５を開けた
金属製または樹脂製の振動板６を使用した構造をもって
いる。As shown in Fig. 3A, the piezoelectric buzzer of the present invention has a structure using a metal or resin diaphragm 6 with porous holes 5 formed in the part where the piezoelectric ceramic element 4 is bonded. .
第４図に本考案品と従来品による周波数と音圧との関係
を示しており、本考案品による特性をａ、従来品による
特性をｂで示し、本考案品の方が良好な周波数一音圧特
性をもっていることが解る。Figure 4 shows the relationship between frequency and sound pressure for the product of the present invention and the conventional product.The characteristics of the product of the present invention are shown as a, and the characteristics of the conventional product are shown as b.The product of the present invention has a better frequency response. It can be seen that it has sound pressure characteristics.
これは、突孔５によって振動板６が軽くなったことと、
突孔５を設けた部分の剛性が弱められ、圧電磁器素子４
の振動を振動板６が抑制せずに入力信号に忠実に振動し
て音圧レベルが全体に高くなることを意味している。This is because the diaphragm 6 has become lighter due to the protrusion holes 5, and
The rigidity of the portion where the protrusion hole 5 is provided is weakened, and the piezoelectric ceramic element 4
This means that the diaphragm 6 does not suppress the vibrations and vibrates faithfully to the input signal, increasing the overall sound pressure level.
なお、これらの特性は第２図に示すような共鳴箱内に圧
電ブザーを収納した状態で測定された。Note that these characteristics were measured with the piezoelectric buzzer housed in a resonance box as shown in FIG.
以上のように本考案は構威されているものであり、非常
に簡単な構戒でもって小さな人力信号で大きな音圧特性
をもつ圧電ブザーを提供することができるものである。As described above, the present invention has been developed and is capable of providing a piezoelectric buzzer with large sound pressure characteristics using a small human input signal with a very simple design.
