Title:
SPEAKER SYSTEM
Document Type and Number:
Japanese Patent JPH03208500
Kind Code:
A
Abstract:
PURPOSE: To provide a speaker system which can faithfully reproduce sound in any band by fixing a voice coil on one end side of a vibrator which coaxially exists in a cylinder having three rooms which is coaxially arranged. CONSTITUTION: The vibrator 5 passes through the center part of the cylinder 8 which coaxially has the three rooms and it horizontally exists in it. The vibrator 5 is made in a hollow state and one end side is fixed to the voice coil 4 receiving sound signal voltage from outside through input terminals 13 and 13'. The central outer peripheral face 5' of the vibrator 5 and right/left gates A' and B' are displaced by the formation of the magnetic circuit of a center pole yoke 1, a plate 2 and a magnet 3. Thus, the wall faces A and B of the cylinder 8 are opened/closed and sound pressure is generated from a high voltage tank 9 or a low voltage tank 10 and air in a constant pressure state, which comes out through a horn 7 that is integrally installed for the upper center opening part of the cylinder 8, is controlled.
