Conventionally, in small electronic devices, piezoelectric buzzers have been located on the back side of circuit boards due to space and other considerations, so coil springs have mainly been used to provide electrical continuity between the circuit boards and piezoelectric buzzers. This coil spring may be soldered to the circuit board (first
(see figure), and because they were fixed to the circuit board using separate parts (see figure 2), the overall cost was high and the number of parts increased, making the structure complicated.

Hereinafter, the present invention will be described in detail based on examples. FIG. 3 shows a conduction structure of a piezoelectric buzzer according to a first embodiment of the present invention. As is clear from FIG. 3, in the present invention, the coil spring 4 consists of two parts, a circuit board contact spring part and a piezoelectric buzzer contact spring part, and each is connected by a recess and a pin part (protrusion) of the case 6. It is fitted into the determined position, and the circuit board 5 is screwed to the case 6 from above. In this state, if the back cover 1 to which the piezoelectric buzzer 3 is attached is fixed to the case 6 by screwing or the like, the pattern on the front surface of the circuit board 5 and the piezoelectric buzzer 3 will be electrically connected. Actually, in order to make the buzzer 3 sound, two such electrical connections are required, but this is not difficult from a structural standpoint.

電子機器を提供できる。[Effects] As described above, in the present invention, since the coil spring etc. have a cast-in structure, assembly is easy, and since soldering etc. are not used,
The cost will also be lower. As for the structure, both the piezoelectric buzzer side and the circuit board side are compressed and conductive with the coil spring, so it is electrically reliable. Also, the coil spring is not a shape that is difficult to process, so the total , it is possible to provide low-cost, high-quality small electronic devices.
