Speaker Mounting Bracket with Acoustic and Airflow Control Baffles

       Disclosed is molded thermoplastic bracket for mounting a
speaker inwardly adjacent to a slotted exterior panel, wherein the
bracket includes surfaces to control the flow of cooling air through
the panel slots and to reduce the transmission of acoustic noise,
generated within the system, through the speaker cone.

      As shown in the figure, a standard type of speaker 10 is
mounted behind an exterior panel 12, being held in place by a molded
bracket 14.  Speaker 10 includes a paper cone 16, driven through
acoustic vibrations by a magnet assembly in a metal shell 18.
Exterior panel 12 includes a number of slots 20, arranged to allow
the outward transmission of sound generated by speaker 10.  Molded
bracket 14 includes speaker mounting hole 22, with flexible clamping
surfaces 24 extending above a clearance slot 26.  Speaker 10 is
mounted into bracket 14 by pressing shell 18 into hole 22.  Bracket
14 also includes various features (not shown) for mounting within a
machine framework in alignment with panel 12.

      The system in which speaker 10 is mounted includes a number of
sources of unwanted acoustic noise, such as a cooling fan (not
shown).  In order to prevent the transmission of such unwanted noise
outwardly through paper cone 16, baffle surfaces 28 are provided in
bracket 14, extending behind cone 16.

      Additional baffle surfaces are provided, as integral parts of
