Abstract: The present invention is a sports bike-type motorcycle with a sound system deployed in major part discretely in the cowling behind the rider. The speakers are incorporated into existing features in the front of the bike, such as in the rearview mirrors. To compensate for the smaller battery of sportbikes but still deliver peak power for dynamic sound, a capacitor in electrical connection with the battery and amplifier provide effective audio response. The sound system, being incorporated into existing structural features in the sports bike, cannot be observed by passers-by and is therefore less vulnerable to theft or vandalism. Also, the profile and aerodynamics, and therefore performance characteristics of the sportsbike, are not changed or compromised by the integration of the sound system within the existing structural features of a sportsbike.

Abstract: An engine sound control apparatus capable of arranging a sound of a frequency that is lower than the fundamental-order frequency of the engine. The engine sound control apparatus detects the frequency of the engine sound and generates a sound signal of a frequency that is in accordance with a control signal and outputting the sound signal generated by the oscillator. Through the interaction between the sound generated by the apparatus and the engine sound, occupants in the passenger compartment will perceive a sound of a frequency that is equal to the difference between the generated sound and the fundamental-order sound. This yields a sound that is lower in frequency than the fundamental-order sound without actually generating a sound of a frequency that is lower than that of the fundamental-order sound.
