In a loudspeaker, what determines the pitch (frequency) of the sound produced?

Q: How do I try a free AQA Physics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live AQA GCSE Physics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for AQA Physics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Physics questions aligned to the AQA GCSE syllabus?

Every question is written against the published AQA GCSE Physics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real AQA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

In a loudspeaker, what determines the pitch (frequency) of the sound produced?

Accepted Answer

The frequency of the alternating current supplied to the coil — The pitch of the sound corresponds to the frequency of vibration of the cone, which in turn matches the frequency of the alternating current driving the coil. The strength of the magnet and the number of turns affect the amplitude (loudness), not the pitch.

Answer

The number of turns on the coil

Answer

The diameter of the loudspeaker cone

Answer

The strength of the permanent magnet

Answer

The frequency of the alternating current supplied to the coil
