A rigid separator (33) is positioned over the open top of the bottom piece. The bottom piece, resonator and separator are all positioned within the cavity of a rigid top piece (13) having the shape of an inverted open rectangular box, the separator being press-fit against the interior surface of the top wall (17) of the top piece. The top wall of the top piece is provided with a recessed area (22) in which a biasing element (51) is disposed, the biasing element being retained in the recessed area by the separator. The top piece, bottom piece and separator are each rotary extrusion molded, from a continuous web, and the various continuous webs are automatically laminated together.
