Abstract
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.
Claims20
A method for controlling the loudness of sound produced by a sonic device, comprising the steps of:
- producing audible sounds from said device;
- detecting the loudness of said produced sounds;
- and
- automatically adjusting the loudness of the audible sounds to a desired loudness.
A method for controlling the loudness of sounds produced by a telephone handset, comprising the steps of:
- receiving transmitted signals corresponding to speech;
- converting said signals into corresponding sonic vibrations;
- sensing the level of loudness of the audible sound with a piezoelectric element;
- and
- adjusting the loudness of the audible sound to a desired level if the level of loudness of the sensed audible sound is unacceptable.
A wireless handset, comprising:
- means for receiving transmitted radio signals;
- means for producing vibrations corresponding to the received radio signals and to signal a sonic or silent alarm;
- means for generating electrical signals corresponding to the loudness of said vibrations;
- and
- means for analyzing said electrical signals and adjusting the loudness of said vibrations to a desired level.
