1. An engine speed sound-warning device, comprising:
- a central processor;
an induction and input unit for obtaining a value of engine speed, and sending said obtained value of engine speed to said central processor;
a setting selection unit including an input interface, via which a selected value is input to said central processor; and
an output load unit adapted to emit a warning sound;
wherein said central processor receives said value of engine speed sent from said induction and input unit, and compares said received value of engine speed with said selected value input via said setting selection unit; and
said central processor emits a signal when said received value of engine speed is larger than said selected value, so as to cause said output load unit to emit the warning sound.

Abstract
An engine speed sound-warning device includes a central processor that receives a detection signal of engine revolution, and compares the received signal with an engine speed value preset via a setting selection unit. When the detected signal of engine speed exceeds the preset engine speed value, a sound is emitted under control to notify and warn the driver.
