A speaker does not produce sounds that travel faster than the speed of light. In fact, according to our current understanding of physics, no information or signal can propagate faster than the speed of light in a vacuum.
When a speaker generates sound, it produces vibrations that travel through a medium, such as air or water, as pressure waves. These pressure waves propagate through the medium and reach our ears, where they are detected and interpreted as sound.
The speed at which sound travels through a medium depends on the properties of that medium. For example, in dry air at room temperature, sound travels at approximately 343 meters per second (about 1235 kilometers per hour). In water, sound travels at a much higher speed of about 1,484 meters per second (about 5,338 kilometers per hour).
It's important to note that the speed of sound is significantly slower than the speed of light, which travels at approximately 299,792,458 meters per second in a vacuum.
So, while a speaker can produce sound waves that propagate through a medium, the speed at which these waves travel is much slower than the speed of light, and they do not violate the fundamental speed limit set by special relativity.
