a sound box refers to a device that can convert an audio signal into sound. In layman's terms, it means that the main box of the speaker or the subwoofer has its own power amplifier, which amplifies the audio signal and then plays back the sound by the speaker itself to make it louder.

the sound box is the terminal of the whole sound system, and its function is to convert audio electric energy into corresponding sound energy and radiate it into space. It is an extremely important part of the sound system, which is responsible for converting electrical signals into acoustic signals for people's ears to listen to directly.

physical model

as we know, the sound-producing part of the speaker is the speaker, and the purpose of the speaker box is to prevent the sound wave signals on the front and back of the speaker diaphragm from directly forming a loop, so that only high-frequency and intermediate-frequency sounds with very small wavelengths can be propagated, while other sound signals are offset by superposition.

the physical model of the speaker is to open a hole in an infinite rigid barrier and install the speaker, so as to ensure that the sound signals on the front and back of the speaker will not form a loop, resulting in a sound wave loop.

However, in actual use, it is impossible to make a loudspeaker infinitely large. Therefore, people use a baffle behind the loudspeaker to form a closed space to ensure the front transmission of sound waves.

the following problem: due to the problem of atmospheric pressure, the larger the box of the speaker is, the more favorable it is to restore the low-frequency sound. Therefore, the volume of the general speaker is calculated according to the speaker size of the bass unit.
