First Claim
Patent Images
1. A vehicular sound effect generating apparatus comprising:
- a waveform data table for storing waveform data in one cyclic period;
reference signal generating means for generating a reference signal by successively reading the waveform data from said waveform data table;
running state detecting means for detecting a running state of a vehicle;
control means having acoustic correcting means having acoustic correcting characteristics depending on the running state of the vehicle, for generating a control signal by using said acoustic correcting means by acoustically changing said reference signal depending on the running state of the vehicle detected by said running state detecting means;
output means for outputting said control signal as a sound effect; and
transmission determining means for determining whether a transmission on the vehicle is a manual transmission or an automatic transmission;
wherein said control means changes said acoustic correcting characteristics of said acoustic correcting means depending on the transmission determined by said transmission determining means.

Abstract
A vehicular sound effect generating apparatus has a controller for determining whether a transmission on a vehicle is a manual transmission or an automatic transmission based on whether a clutch signal is generated or not, and automatically changing weighting gain characteristics as acoustic correcting characteristics stored in a sound pressure adjuster depending on the determined transmission. The vehicular sound effect generating apparatus generates a sound effect in a vehicle cabin depending on the manual transmission or the automatic transmission.
