We know that the sound component of a speaker is a speaker, but why use a speaker instead of listening directly to the speaker?
The purpose of the speaker box is mainly to prevent the sound wave signals on the front and back of the speaker diaphragm from directly forming a loop, causing only high-frequency and intermediate-frequency sound with a small wavelength to be transmitted, and other sound signals are The superposition cancels out.
The physical model of the speaker is to open a hole in an infinite rigid baffle to install the speaker, so as to ensure that the sound signal on the front and back of the speaker will not form a loop, resulting in a sound wave loop.
However, in actual use, the speaker cannot be made infinitely large. Therefore, people use a baffle behind the speaker to form a closed space to ensure the frontal transmission of sound waves.
The ensuing problem: after the speaker is sealed, due to the atmospheric pressure problem, the larger the speaker cabinet, the more conducive to the restoration of low-frequency sound. Therefore, the volume of the general speaker is calculated as a compromise based on the speaker size of the mid-bass unit.
But many environments still do not allow too large cabinets. In order to further reduce the volume, people have designed baffles, inverted tubes, resonators, etc. in the cabinets according to the characteristics of sound waves and the requirements of strengthening low-frequency sound wave reproduction. In the low frequency band, the sound signal of a certain wavelength is enhanced, and the influence of atmospheric pressure on the sound restoration is further reduced.
The speaker is the weakest component in audio equipment, and it is the most important component for audio effects. There are many types of loudspeakers: according to their energy conversion methods, they can be divided into electric, electromagnetic, piezoelectric, digital, etc.; according to the diaphragm structure, they can be divided into single cones, composite cones, composite horns, and the same There are many kinds of shafts; according to the beginning of the diaphragm, it can be divided into cone type, dome type, flat type, belt type, etc.; according to the playback frequency, it can be divided into high frequency, intermediate frequency, low frequency, ultra low frequency and full-band speakers; According to the magnetic circuit form, it can be divided into external magnetic type, internal magnetic type, dual magnetic circuit type and shielded type; according to the nature of the magnetic circuit, it can be divided into ferrite magnets, neodymium boron magnets, and alnico magnet speakers; The membrane material can be divided into paper and non-cone speakers.
