摘要： A synthetic chloroprene rubber adhesive composition which contains carboxylated synthetic chloroprene rubber for the main ingredient thereof and further contains chlorinated polypropylene and/or a chlorinated polypropylene derivatives. The adhesive composition can strongly bond various components to polypropylene used for a speaker frame, etc. unlike conventional synthetic chloroprene rubber adhesives which have insufficient adhesion strength in this application.

摘要： A speaker comprising a magnetic circuit containing at least a magnetic gap, a frame connected to the magnetic circuit, and an integral unit consisting of a ring shaped voice coil bobbin unit which is wound around with coil to be coupled in the magnetic gap, and a diaphragm unit formed in the shape of an inverse letter “U” disposed on an upper edge of the voice coil bobbin unit. This speaker provides enhanced rigidity, a reduction in production/assembly cost, and an improved sound pressure level.
