Audio Earphone Sound Pipe

      This article describes the attachment of a pair of earphones to
computer systems that use a beeper for a sound-generating device.

      The device disclosed herein provides external audio via
earphones in products that normally do not support this function,
such as a planar assembly that uses a beeper for a sound- generating
device.

      The device of this disclosure is shown in the diagram below.  A
length of 1/2" plastic pipe is attached to the beeper.  This pipe is
routed through the system box to the mounting panel.  The mounting
panel contains a hole through which a 1/2" to 3/8" hose barb is
inserted and affixed.  A length of 3/8" plastic hose is then attached
to the hose barb, and a set of earphones is connected to the 3/8"
hose. The earphones are similar to the headphones that are used on
airlines or attached to a doctors' stethoscope.

      The implementation of this solution is entirely passive and
does not affect the electromagnetic compatibility/electromagnetic
interference profile. Additionally, when implemented, the system
beeper can still be heard outside the covers.  This can be important
when listening for the "beeps" when the system is first powered on
and prior to affixing the earphones.

      This implementation may also include a volume control by
placing a squeeze-type constrictor on the audio sound pipe like an
intravenous (IV) drip control or a petcock.
