Various speaker speakers introduce reflective speakers:
For the most design. When the single diaphragm sounds, its sound hits the sound wave rebounded by the rear plate, and the reversed sound wave is transmitted through the reflective duct. The size of the reflection hole and the length of the catheter affect the extension of the low frequency. Therefore, the proper aperture and the length of the catheter must be designed according to the characteristics of the single body to achieve the best speed sense and good low frequency extension.

Closed speaker:
The speaker is fully closed and closed. Although it can get a good low-frequency sound design, it will greatly reduce the efficiency of the speaker. If you want to get good control, you must use super power to push it. Otherwise, the low-frequency speed will be delayed. The phenomenon.

Back spoke speaker:
It is a closed-type speaker, mainly adding a single diaphragm-only unit (bass, when the bass vibrates, it uses air to push the extension of the back-spray diaphragm. But it has the disadvantage of low efficiency and slow speed. Welcome to China Home Theater Network!

Isobaric speaker:
It can increase the energy of low frequency, but the closed design will cause low efficiency. When two monomers are simultaneously sounding, if the sound is out of sync, it will affect the transient response of the speaker.

Transmission speaker:
The extension of the low frequency is increased by a longer transmission pipe, but an excessively long pipe causes a low frequency to be slow.
Professional speaker structure:

Reflective speakers:
Its design principle is the same as that of household reflective speakers.

Horn speaker:
With the feature of good horn diffusion, the bass is squeezed first, and then the horn swings to transmit the sound farther. In large outdoor concerts, the general low frequency cannot be transmitted farther, so the low frequency must be transmitted out of the bass by the horn extrusion.
The disadvantage is that the low frequency extension is poor.
