Abstract:
An electronic apparatus, comprising:an electronic data input device; an electronic data output device; electronic data processing circuitry coupled between said input device and said output device; a function performing mechanism associated with said processing circuitry that produces sound waves of audible noise; an airflow duct that functions as a conduit to provide airflow for said function performing mechanism; and a compressible air chamber coupled to said duct; wherein said duct and said chamber are configured such that said duct includes a within duct egress orifices that permits sound waves propagating through said duct to be communicated to said chamber, and said chamber defines with the exception of said ingress orifice a substantially closed volume that functions to suppress the sound waves, and wherein at least one divider between said chamber and an adjacent chamber is coupled to a heat sink, said heat sink being coupled to a heat producing integrated circuit.
