Abstract
A wideband voice electro-acoustic apparatus for a wireless telephone, including a mouthpiece for a wireless telephone. The mouthpiece has a wideband voice frequency response/passband in the frequency range of 200 Hz to 7000 Hz. The apparatus also includes an earpiece for a wireless telephone. The earpiece has a wideband voice passband in the frequency range of 200 Hz to 7000 Hz. The wideband voice electro-acoustic apparatus improves the voice quality of wireless voice band communication over that available using a conventional wireless telephone having an electro-acoustic passband smaller than 200 Hz to 7000 Hz.
