Different Types Of Speakers (Characteristics Of Speakers Box )




4. The Labyrinth Enclosure is named after the transmission line of classical electrical theory. The sound pipe made of sound absorbing wall plate is set behind the speaker, and its length is 1/4 or 1/8 of the required low frequency sound wavelength.

In theory, it attenuates the sound wave coming from the back of the cone basin to prevent it from reflecting to the open end and affecting the sound radiation of the best bass speaker. However, the actual uplink transmission line speaker has a slight damping and tuning effect, increasing the sound output of the speaker near or below the resonant frequency, and reducing the stroke while enhancing the bass output.

Usually, the sound pipes of this kind of speakers are mostly stacked in a labyrinth shape, so they are also called labyrinth type or labyrinth type.


5. The Drone Cone Enclosure is a branch of the bass reflective speaker, also known as the empty paper cone speaker. It was published by Olson and Preston in 1954. Its opening outlet is replaced by an empty paper cone (passive cone) without magnetic circuit and voice coil.

The radiation generated by the vibration of the non source cone is in the same phase with the forward radiation of the speaker, The compound sound harmony formed by the air in the box and the passive cone basin support components and the passive cone basin mass form resonance to enhance the bass.

The main advantage of this type of speaker is that it avoids the unstable sound produced by the reflected sound hole. Even if the volume is small, it can obtain good sound radiation effect. Therefore, it has high sensitivity, can effectively reduce the working radiance of the speaker, has little standing wave effect, and the sound is cold and transparent.


6. The coupling cavity speaker is a box structure between the closed type and the bass reflex type. It was published by Henry Lang of the United States in 1953. Its output is from the sound outlet driven by one side of the cone basin, and the other side of the cone basin is coupled with a closed box.

The advantage of this kind of best small speaker with bass is that the amount of air pushed by the speaker increases greatly at low frequencies. Because the coupling cavity is a tuning system, when the cone basin motion is limited, the output of the sound outlet does not exceed the sound output of the individual cone basin, which broadens the range of low frequency playback, so the distortion is reduced and the power bearing rate is increased.

The A · S · W (AcoustIC Super Woofer) speaker released by Kohiko Kajima of Lo-d, Japan, in 1969 is a coupling cavity speaker, which is suitable for undistorted reproduction of bass with small caliber long stroke speakers.


7. For speakers with bass for home, Folded horn is mostly used. Its Horn Horn is coupled with large air load at the mouth, and the diameter of the drive end is very small.

The back of this type of speaker is fully sealed, and the pressure in the box is mostly on the back of the speaker cone. In order to keep the pressure in front of and behind the cone basin balanced, the phase reversal horn is installed in front of the loudspeaker.

Folding horn speaker is a derivative of the inverted speaker, and its sound effect is better than the general bass reflex speaker of the closed speaker.

According to the number of loudspeaker units, 2.0 speakers, 2.1 speakers, 5.1 speakers, etc.
According to the box material, it can be divided into wooden speakers, plastic speakers, metal speakers, etc.
