An apparatus and system automatically adjusts the acoustic output of a wireless handset. The system includes an actuator, a piezoelectric disk and a controller. The actuator generates vibrations that produce sound. The piezoelectric disk detects the acoustic vibrations of the actuator and the associated loudness of the sound. The controller analyzes the detected sound and, if necessary, adjusts the actuator or an input amplifier of the actuator to produce a desired acoustic output.
