    my theory is that the full speaker membrane vibrates at x hz while its run by waves at y hz waves run by smaller waves at z hz and so on

    is this correct?

    whats the right answer if not ?

    Whatever your theory is (since it's not understandable) it is wrong.

    Ya... an electrical current is applied to a coil that produces a magnetic field which vibrates a diaphragm, which in turn produces sound waves at the desired frequency.

    I had to look that up on wikipedia, you could have done the same.

    yes thanks but how can the diaphragm vibrate at the same time at 100 hz and 200 hz as to produce a chord ?

    It is no different than how we hear a chord played by a musical instrment. A pressure wave reaches our ears which is a complex waveform with several frequencies superimposed. The ear is capable of resolving the signal from the time domain to the frequency domain, and we hear the different frequencies.

    yeah thanks so could it be described as bigger waves of certain frecuency run by smaller waves at other frecuency and so on?

    im really amazed by what a pulsating diaafragm can do
