ABSTRACT:
A volute horn is assembled by integrally attaching a horn body to a resonating device forming a volute sound path. The horn body includes a vibration generating unit for vibrating diaphragm to create a sound, and a cover facing the outer surface of the diaphragm provided so as to block an opening in a housing. The resonating device is formed of a frame and a base. The frame is formed so that the bottom of the sound path is open, and the base is integrally secured to the bottom of the frame so as to block the sound path in an airtight manner. A first opening is formed in the cover, and a second opening is formed in the base. Sound produced by vibrating the diaphragm is transmitted through the first and second openings and into the volute sound path. The first opening communicates with the second opening in an airtight manner.
