Title:
【発明の名称】制御された柔軟なダイアフラムを備えた改良型オーディオトランスジューサ
Document Type and Number:
Japanese Patent JPH03503587
Kind Code:
A
Abstract:
An improved audio transducer includes a diaphragm having a pair of cylindrically-shaped webs that provide greater bandwidth, reduced distortion and greater horizontal dispersion of sound. The audio output of the transducer is further improved by forming the diaphragm of a polyvinyl fluoride film. Other improvements include the use of damping pads to damp internal sound waves and damping strips on the diaphragm to minimize distortion at the resonant frequency of the transducer.
