I recently bought a 3-24V Piezo Electronic Tone Buzzer Alarm. I would however like to increase the volume. Bare in mind that my electronic knowledge is (unfortunately) at the very basic level of; find a tutorial/blog, follow instructions to plug in the gpio cables, make celebratory sound because it works!
From what I could gather, the 5V pin on the Raspberry gave less volume than if I just connected the buzzer directly to a 9V battery. So more volts equals more volume? I then figured that I would probably need to set up a circuit in which I connect the onboard 5V to a transistor, to jump up the voltage to 24V, to get maximum volume. I thought something like this might help (https://www.pishop.co.za/store/dc-dc-adjustable-step-up-power-module), but it seems more expensive than needs to be? Something like this might be cool if I needed to keep changing the voltage, but I know at which voltage I want to end up.
Could someone please assist with a very basic circuit from the Raspberry Pi GPIO to the buzzer, allowing me to get maximum volume (24V) from the buzzer, with the names of all the transistors, resistors, etc that I would need.
