Introduction
The SF-9324 Variable Frequency Mechanical Wave Drive
lets you drive wave experiments with ease and accuracy.
You will need a waveform generator with an amplifier
capable of producing current up to 1.0 A —we recom-
mend the PASCO Model PI-9587C Function Generator with
a built-in amplifier and an accurate, digital frequency read-
out, or the PI-9598 Student Function Generator.
The mechanical wave driver is a strong, long-throw
speaker, with an attached drive arm. The speaker will
vibrate with any frequency you can produce with your
waveform generator, from 0.1 Hz to 5 kHz, and with am-
plitudes up to 7 mm p-p at the low end of the frequency
range. The waveform need not be a sine wave; other
waveforms, such as square, triangular, or sawtooth, can
be used.
You can attach the Mechanical Wave Driver to a wire or
string using the provided banana plug connector, as
shown on the following page. You can also design your
own connectors. One method is to solder a piece of stiff
wire to a banana plug connector, then bend the wire as
needed.
The Mechanical Wave Driver is designed to sit upright, or
on its side (rest it on the side with the rubber feet). It can
also be mounted on a 1/2" rod in either a vertical or hori-
zontal position.
