【発明の詳細な説明】
本発明は部品点数がきわめて少なく、かつ組立も著しく
容易で特性的にも優れた圧電ブザーを提供するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a piezoelectric buzzer that has a very small number of parts, is extremely easy to assemble, and has excellent characteristics.
従来の圧電ブザーにおいては、圧電ブザーェレメントと
端子を接続する上でリード線をハンダ付けして用いてい
たため、リード線の断線、ハンダ付け不良等が問題とな
っていた。In conventional piezoelectric buzzers, lead wires are soldered to connect the piezoelectric buzzer element and the terminals, which causes problems such as breakage of the lead wires and poor soldering.

せんとするものであり、以下その一実施例について添付
の図面とともに説明する。In addition, in the case of the type in which the element is housed in an insulating case, the element is sandwiched between the case and the cover that is iron-fitted to the case, which has the disadvantage that the fixation is unstable and it is difficult to obtain stable characteristics. Furthermore, the terminals were also press-fitted into the cover, which required a lot of man-hours.
The present invention aims to provide a piezoelectric buzzer which has greatly improved the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

のである等、数々の利点を発揮するものである。Then, the case components 2b, 2b'' are fixed together by heat, ultrasonic waves, or the like. As a result, the piezoelectric buzzer element 1 is inserted into the grooves 2c, 2c' of the case components 2b, 2b', and the terminals 3, 4 are fixed in contact with the element 1 and the diaphragm, respectively. Note that the case components 2b and 2b' can be constructed using separate components. As described above, the piezoelectric buzzer of the present invention has a very small number of parts, is very easy to assemble, and has a contact structure that does not use lead wires, so it has extremely stable characteristics. Moreover, it exhibits many advantages, such as having sufficient pull-out strength to allow the terminal to be easily assembled.
