ACTIVE SOUND GENERATION DEVICE

An active sound generation device is proposed to generate a sound effect in a vehicle interior. The active sound generation device includes: a low sampling rate generation part, generating a low sampling rate signal by lowering a sampling rate; a processing frequency setting part, setting the sampling rate of the low sampling rate generation part; a high sampling rate generation part, amplifying a sampling rate of the low sampling rate signal to generate a high sampling rate signal as the sound effect; and a speaker, outputting the sound effect.
