The role of sound-Alice factory

It is an extremely important part of the sound system, because it is responsible for the key task of converting electrical signals into acoustic signals for human ears to listen directly to. It has to directly deal with human hearing, which is very sensitive. And has a strong ability to distinguish the timbre of complex sounds.

Since the human ear’s subjective perception of sound is the most important criterion for evaluating the sound quality of an audio system, it can be considered that the performance of speakers plays a key role in the sound quality of an audio system.

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- and mid-frequency sound with a small wavelength to be transmitted, while other sound signals are superimposed and cancelled Lost.

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 infinite. 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 based on the speaker size of the mid-bass unit to calculate a compromise.

However, in many environments, too large cabinets are still not allowed. In order to further reduce the volume, according to the characteristics of sound waves and the requirements of strengthening low-frequency sound waves, baffles, inverter tubes, resonant cavities, etc. in the boxes are designed, mainly for 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 device 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 frequency range 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.

Alice's signs are flat in workmanship and strong in three-dimensionality. They are a common surface treatment process and have a wide range of applications. For example, signs can be used in audio, household appliances, refrigerators, computers, and security products.
