Abstract

See full text

A resonant structure for loudspeaker includes a basket defining a front opening and having an annular magnet mounted therein; a voice coil suspended inside the magnet; a diaphragm connected at a suspended flange to the front opening of the basket; at least one flexible suspension member spaced behind the diaphragm for connecting to a rear opening of the basket; and an inner frame having a front end glued to a rear wall surface of the diaphragm, a central area to the voice coil and a rear wing member to the flexible suspension member. When the voice coil moves forward and backward on the inner frame, best possible harmonic resonance between the diaphragm and the flexible suspension members can be obtained. The loudspeaker is effectively reduced in height, and bass response is enhanced to ensure upgraded sound quality.
