    摘要： A case is formed by an upper case and a lower case, and a buzzer is provided in the case. Two coil springs are securely mounted in holes formed in the lower case. A lower portion of the coil spring is projected from an underside of the lower case. A pair of leads electrically connect both ends of the coil to the coil springs, respectively.

    摘要： A surface-mounted electromagnetic sound generator generates sound by causing a vibration plate to vibrate by an electromagnet which includes a yoke and a coil housed in a case. The yoke has a magnetic-circuit board an outer circumferential portion of which is provided with a drawn portion, the drawn portion being imbedded in the case by insert-molding when the case is molded.
