Exactly the opposite. Pulse width modulation means your are modifying the duty cycle at a fixed frequency. I just want to clear that up for viewers. PWMing a buzzer will not produce different frequencies.
@fennecfanatic ehhh sort of not really. I think buzzers usually do best at 50% duty cycle and then probably taper off above and below that but PWM is not a good way to change volume. I tried it once a long time ago and remember noting not to do it again. Made it sound weird and screwed up.
The speaker looks like something out of an alarm clock... ;-)

hve to do to increase the sound thanks pleas.

It's not PWM (Pulse Width Modulation) but PFM (Pulse Frequency Modulation). Pulse width is constant 50% (not modulated).

@GTechno13 so PWM into a buzzer would produce the same frequency at different amplitudes?

This is NOT PWM.

@GTechno13 sure it is. It's pwm with a 50% duty cycle and a varying frequency.
