Abstract (en)
A controller for controlling the energization of a coil 44 is constituted by an IC chip 51 that serves as a single package component in which a plurality of electronic components is sealed with a sealing material. As a result thereof, a horn device 10 which can meet the needs of productivity improvement, cost reduction, and a reduction in size and weight, while allowing improvements in reliability without the need for a control circuit board can be achieved. The IC chip 51 itself controls the energization of the coil 44, that is, the IC chip vibrates a diaphragm 22, thereby also allowing elimination of contacts. Consequently, the horn device suppresses generation of abrasion powders or the like due to contact with the contacts, and thus prevents malfunction of the IC chip 51, thereby improving reliability.
