Abstract
A free air suspension loudspeaker consists of a pyramid shaped sound radiator (2) suspended by four tendons (3) fixed at each corner of a frame (1). A loudspeaker driver (7) is mounted onto the sound radiator. The front of the sound radiator is covered with sound transparent cloth (5). The tension on the tendons can be adjusted according to the required sound, by turning the nuts (4). <IMAGE>
Description
SPECIFICATION
Free air suspension loudspeaker
A free air suspension loudspeaker enclosure, con
sists of a main frame (1). A pyramid shaped, sound
radiator (2), is suspended by four strips of sheet
metal or steel wire (3). The tension is adjusted by four nuts (4). The front of the radiator is covered with sound transparent cloth (5), made of a stretchable material, applied on the radiator at the maximum tension. The complete area of the back of the enclosure is open. The whole unit stands on the floor or shelf, supported by two strips of steel (6). A loudspeaker driver (7) is mounted onto the sound radiator.
1. A free air suspension loudspeaker consists of a pyramid shaped sound radiator (2) suspended by four tendons (3) fixed at each corner of the frame (1).
A loudspeaker driver (7) is mounted onto the sound radiator. The front of the sound radiator is covered with sound transparent cloth (5). The tension on the tendons can be adjusted according to the required sound, by turning the nuts (4). The purpose of this principle is to transmit the driver's sound vibrations onto a freely moving sound radiating area, as big as technically possible, radiating the sound into the atmosphere, front and back of the loudspeaker unit.
A. The tendons as claimed in claim 1, can be made from sheet metal or steel wire.
B. As claimed in claim 1, the front of the sound radiator is covered with sound transparent cloth (5)
made of stretchable material, applied on the radiator at the maximum tension.

A free air suspension loudspeaker system, consists of a main frame (1). A pyramid shaped sound radiator (2) is suspended by four strips of sheet metal or steel wire (3). The tension is adjusted by four nuts (4). The front of the radiator is covered with sound transparent cloth (5) made of stretchable material, applied on the front of the radiator at the required tension, to vibrate as a sound amplification diaphram at the same frequency of the driving unit.
The complete area of the back of the frame is covered with a type of open weave cloth, to allow maximum sound transparency. The whole unit stands on the floor or shelf, supported by two strips of spring loaded steel (6). Four holes (7) to allow the
passage of air between the front and the back of the resound radiator, the diameter varying according to the size and type of the driver and ambiental conditions.
