A Simple Sine Wave Oscillator

Once you have built it, Set the frequency as desired using the `Frequency Control`. Than using an Oscilloscope you can adjust for best waveform using the `Clip Control`. Due to the Sharp Rise and Fall times of Square Waves, they try to make a speaker cone go from a full out position to a full in position. These continuous sudden changes in the spe

aker cone movement, will eventually Rip the coil from its form. Than the speaker produces a Fuzzy tone and eventually will quit all together! This Square wave Effect is also produced when "Over Driving your Stereo", as that also produces Square Waves. More speakers are damaged in this way than by Excessive power. Under-Powered Amplifiers can be bad if you like loud music. Having "Power to Spare" on an Amplifier is good and reduces the possibility of Square Wave Distortion and Speaker Damage! Good Quality Musical Instrument Speakers are Specially Designed to better handle Square Wave Distortion, Because most musical instruments produce a fair amount of it. However recorded music does not faithfully reproduce square wave distortion, so normally it isn`t a problem for Home type speakers. However, Over-driving a Power-amp WILL definately produce Square waves and damage these types of speakers. Sometimes very quickly.
