DENSO FLAT HORN DOUBLE PIN 1BOX

Flat horns use a vibrator to amplify sound according to its resonance.

Flat horns are constructed so that the air gap is narrow, and the armature collides with the core. The impact force generated from the collision creates higher harmonic components that resonate at a number of times the fundamental frequency, and this energy excites the vibrator, making it resonate and amplifying the sound pressure.

Flat horns amplify by resonating this kind of mechanical collision force, so they have a sharp frequency characteristic and highly efficient amplification, making them the most compact type of horn. In addition, they have a sharp and stimulating timbre that is very effective for warnings.
