Question

1. the tone of the sound produced by a speaker is determined by the number of times the speaker moves in and out in a second.

true

false

Explanation:

Define tone and frequency

Using the Speaker Physics knowledge point, we analyze how a speaker cone produces sound. The tone (or pitch) of a sound is determined by its frequency, which is the number of complete vibrations or cycles of sound waves produced per second.

Relate speaker movement to frequency

A speaker produces sound waves by moving its cone back and forth. One complete in-and-out cycle of the speaker cone corresponds to one cycle of a sound wave. Therefore, the number of times the speaker moves in and out in one second directly determines the frequency of the sound wave.

Connect frequency to perceived tone

Since the frequency (cycles per second, measured in Hertz) determines the pitch or tone of the sound, the statement is correct. A higher number of movements per second produces a higher-pitched tone, while a lower number produces a lower-pitched tone.

Answer:

• True (Correct answer)
• False
