Abstract
A automatic variable frequency electrolarynx with a microcontroller that generates a random but controlled frequency that creates a random tone. The controlled random tone allows the user of the electrolarynx to use the device without the monotone of standard electrolarynx. The electrolarynx also includes an encoder that allows the user to easily adjust the base tone of the device. The electrolarynx also includes an integrated LED light in the on/off switch to indicate whether the encoder is in volume control or tone control mode. The microcontroller also conducts an automatic power source check, and produces a musical tone when the battery is low.
