不都合が生ずる。 FIG. 2 shows the piezoelectric buzzer e attached to an electronic device. The printed circuit board f to which the piezoelectric buzzer e is attached is mounted on the inner wall surface of the case g of the electronic device with the electrical component h provided on the board f facing outward, so that the sound emitted from the piezoelectric buzzer e is transmitted through the hole d of the case c. is released into the case g of the electronic device as shown by the arrow. Therefore, the sound of the piezoelectric buzzer e becomes muffled and not clear.
The printed circuit board f is turned over and attached to the inner wall surface of the case g of the electronic device, and a hole is provided in the wall surface of the case g opposite to the hole d of the case c of the piezoelectric buzzer e.
It is possible to emit sound from this hole, but
The fixation of the printed circuit board f to the case g lacks stability, and the space on the electrical component mounting surface of the printed circuit board f that is not used for electrical components cannot be used effectively.

な音が得られる。 3 and 4, the piezoelectric buzzer 4 includes a piezoelectric vibrator 9, a diaphragm 10 to which the vibrator is bonded, and a case 1 that supports the vibrator. The case 1 is composed of case members 1A and 1B, and the edge of the diaphragm 10 is supported by the upper end surface of the case member 1A and the step part of the case member 1B.
A shows electrodes 11 provided on both main surfaces of the piezoelectric vibrator 9.
Terminals 2, 2 connected to the diaphragm 10 are provided, and a hole 3 for emitting sound generated by the vibration of the diaphragm 10 is provided. The printed circuit board 5 is an electrical component 1 used in electronic equipment such as a video tape recorder.
For example, a boss 1 is provided on the inner wall of the electronic device case 7 on which the piezoelectric buzzer 2 and its driving parts are mounted.
It is fixed at 3. A hole 3 in a case 1 of the piezoelectric buzzer 4 faces a hole 6 provided in a printed circuit board 5 and also faces a sound emitting hole 8 provided in an electronic device case 7. In this way, when an electronic device is activated and, for example, the piezoelectric buzzer 4 for generating a confirmation sound for switch operation rings, the sound generated from the diaphragm 10 is generated by the case 1.
The sound is emitted to the outside through the hole 3 of the printed circuit board 5, the hole 6 of the printed circuit board 5, and the sound emitting hole 8 of the electronic device case 7, and clear sound is obtained.

利用できる効果がある。 Then, the printed circuit board 5 faces the electronic device case 7 with the main surface on which the electrical components 12 and the piezoelectric buzzer 4 etc. are not attached, and
Since it is screwed to the base plate 5, it can be stably fixed without any accessory parts, and the space on the electrical component mounting surface of the board 5 that is not used for electrical components can be effectively used for electronic equipment.
