The principle of column speakers is mainly based on its internal structure and working mechanism. Column speakers are usually composed of multiple speakers arranged and combined to form a speaker array. This structure allows the sound energy to be concentrated in a specific direction, resulting in stronger directivity and clearer sound effects.
Internal structure and working mechanism
The core of the column speaker is its internal speaker array. These speakers are usually paper cone speakers, which are arranged in a straight line and connected in phase to form a columnar structure. This arrangement makes the radiation angle of the speaker similar to that of a single speaker in the horizontal direction, but in the vertical direction, as the number of speakers increases, the radiation angle will gradually increase, especially in high-frequency sounds, the sound beam can be transmitted in a certain direction, forming a strong vertical directivity.
Sound propagation characteristics
Column speakers have obvious directional characteristics in the vertical direction. As the number of speakers increases, the sound beam becomes narrower, the energy is more concentrated, and the directivity is stronger. When the length of the sound column is fixed, the higher the frequency, the narrower the sound beam and the stronger the directivity. This characteristic enables the column speakers to effectively control the propagation of sound in the vertical direction, forming a "dish"-shaped three-dimensional radiation effect, which is suitable for use in situations where strong directivity is required.
