Abstract

Sound from within the loudspeaker enclosure 1 passes into duct 4 and exits the duct between two spaced apart surfaces 6, 8. Duct 4 may comprise a plurality of internal tubes (see figs. 5 and 6). <IMAGE>

Description

HORN STAND FOR LOUDSPEAKERS FOR PRECISION SOUND RADIATION.
This invention relates to precision sound radiation Horn stand function is to increase low frequencies from 20Hz to 2500Hz and above but with high precision as shown in figure 1, 2, 3, 4, 5 & 6 so that such musical instruments as string bass, drums piano saxephone etc are clearly heard more precisly than it is possible with normal horn.This is achieved by tube 4 fig 5 & 6 receiving radiation 5 into energy recovery chamber 18 by resonance in the 1 to 4 internal tubes fig 6 multi-resonant peaks are set up 19 and with membrane reflex a gain up to 18 dB increase of output is developed in the spaces 20 along the tubes in the 4 and finally emerges high definition sound at 7 through dishes 6 and 8, the loudspeaker has a hole cut out at 13 and all is fixed to 4, gap 9 lets radiation to gap 10 into air or gap 17 in box 16 existing reflex is 2, deflector 3 to avoid standing valve 14 spikes for leveling, 15 are dish spacers box 16 and opening 17 from frequency along periphery 21 horn stand is used to support speaker and utilise and recover energy from inside loadspeaker fig 1. Fig 1 horn stand fig 2 3 & 4 horn column stands item 22 rivets.

Claims (7)

1 The horn stand for loudspeakers figure 1
2 3 4 5 & 6 comprises loudspeaker any good quality fixed to item 4 in which stand several fixed together fig 6 tubes with gap 7 above dish 8 length of fixed item 22 rivetted tubes 400 - 2800mm, 6 and 8 are dishes
15 spacers gap 9 10 and 17 and spikes 14 and periphery 21. Fig 1 horn stand fig 2 3 & 4 horn column 2.The horn stand of three types 1 2 3 4 are tuned as reflexes to resonate at
3 to 4 different frequencies to give 3 to
4 peaks in two modes one as multi reflex and mode two as 2-4 membrane reflex curve outputs to give precision wavelength output, from 20Hz to 2500Hz.
3.The horn stand is used for purpose of energy recovery otherwise wasted energy in the attached loudspeakers, through hole 13. Gain 18Db 4.Horn stand invention is used to radiate precise sound whilst supporting loudspeaker
5.Walls 16 opening 17 and periphery 21 used for frequency development, to obtain precise definition of frequency. Between 20Hz and 2500Hz.
6.Deflector 3 stops standing wavelength to dish 6
7.Box 16 opening 17 and 21 direct sound at listner.
