摘要

Disclosed is a sound generating device for vehicle, more particularly, in case of fastening a sound generating device for outputting artificial engine sound (for example, start-up, or accelerating etc.) onto the automobile vehicle's surface, for example the bonnet, the sound generating device's sound transfer face is pressed to the bonnet, and the sound or vibration of the sound generator is dispersed and output outwardly through the bonnet without attenuation.

主权项

1. A sound generating device for vehicle, the sound generating device comprising:
a sound generator vibrating to output sound signal corresponding to a sound source, which has a coil applied electric alternating signals that interacts with a magnetic circuit including a magnet; a disperser in the vehicle, which comprises a double layered plate formed by a first disperser member and a second disperser member, or comprises a one layered plate formed by a first disperser member and a support frame; and a generator housing to hold the sound generator between the first disperser member and the second disperser member or the support frame, and to transfers three-dimensionally the sound generated by the generator to the disperser.
