Electro-larynx

A linear transducer, for use in an electro-larynx having a waveform generator that produces an input signal and a power source, said linear transducer comprising:

• A. an armature assembly, which receives said input signal characterized by a frequency spectrum and vibrates as a function thereof;
• B. a suspension assembly coupled to said armature assembly;
• and
• C. a coupler disk, coupled to said suspension assembly, wherein a vibration in said armature assembly causes a corresponding vibration of said coupler disk characterized by a frequency spectrum according to a linear function of said input signal, whereby the frequency spectrum of said vibration matches said frequency spectrum of said input signal.

An electro-larynx comprising:

• a waveform generator comprising:
• A. glottal sample data stored in an electronic memory, wherein said glottal sample data is defined over multiple cycles;
• B. a pitch adjuster, configured to add pitch information to said glottal sample data;
• C. a mixer, configured to add amplitude information to said glottal sample data;
• D. an equalization filter for generating from said glottal sample data, pitch information, and amplitude information, a base digital input signal having a predetermined frequency response;
• and
• E. a digital to analog converter, configured to transform said base digital input signal into an input signal, characterized by a frequency spectrum;
• a linear transducer configured to receive and transform said input signal into a corresponding output vibration of a throat engagement portion characterized by a frequency spectrum, said output vibration being a substantially linear function of said input signal whereby the frequency spectrum of said vibration matches said frequency spectrum of said input signal.

An electro-larynx comprising:

• A. a waveform generator configured to selectively generate an input signal characterized by a frequency spectrum, wherein said input signal has a harmonic structure corresponding to a normal glottal excitation, defined over multiple cycles;
• B. a linear transducer having a throat engagement portion, said transducer configured to receive and transform said input signal into a corresponding output vibration of said throat engagement portion characterized by a frequency spectrum said output vibration being a substantially linear function of said input signal whereby the frequency spectrum of said vibration matches said frequency spectrum of said input signal;
• and
• C. a power source.
