Definitions
- the present invention relates to an audio distributor for connecting an input sound signal port to a plurality of output sound signal ports through the operable interaction a plurality of photo resistors with at least one light emitting diode.
- the audio distribution systems require complex, expensive production technologies.
- the audio distribution systems include electronic interfaces and computer controls to allow performers to direct sound signals to the desired locations.
- the audio distributor permits musicians, disc jockeys, theatrical sound technicians, and multimedia artists to easily direct a sound signal to any one or more of a plurality of peripherally located speakers in order to create an effect of movement around the audience/space.
- the audio distributor accepts at least one low-power sound input and directs the input to at least one plurality of output channels in accordance with the manual rotation of the controller disc by the performer/technician/artist. Motorization and computer control of this motor would also be possible, but not required.
- the audio distributor does not use any chips, nor require expensive production technologies, so that cost to produce the audio distributor may be kept low. Performer interaction with the device is very direct, since no computers or electronic interfaces are required. Sound flow from one speaker to another is smooth, in contrast to reed relays or multiplexer chip solutions. [0006] Other applications of the present invention will become apparent to those skilled in the art when the following description of the best mode contemplated for practicing the invention is read in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
- Figure 1 is a top view of an LED rotor disc according to the present invention.
- Figure 2 is a side cutaway view of the LED rotor disc of Figure 1;
- Figure 3 is a side cutaway view of a base according to the present invention.
- Figure 4 is a top view of the base and internal components according to the present invention.
- the audio distributor 10 includes a rotatable disc 12 supported by a stationary base 14 (seen in Figures 3 and 4).
- the rotor disc 12 supports an on-off switch 16 and a directional indicator light emitting diode (LED) 18.
- the directional LED 18 indicates the current output direction of a light emitting diode 20 supported by the central shaft 22.
- the rotor disc 12 can enclose batteries 24, by way of example and not limitation, such as two AAA cell batteries.
- Appropriately sized resistors 26, 28 can be positioned between the batteries and the LED 16, 18 as required.
- the resistors 26, 28 can be 390 ⁇ resistors. A higher value resistor may be necessary for the LED 20 on the rotating shaft 22, since the light may be too bright otherwise.
- the rotor disc housing 12 can include a shaped portion, such as a dimple or depression 30 to facilitate turning the disc 12 by the operator.
- the stationary base 14 supports a bearing 32 for receiving the shaft 22 allowing rotation of the rotor disc 12 with respect to the stationary base 14.
- a plurality of photo resistors 34, 36, 38, 40 are supported within the base 14 in an appropriate position to be operably actuated in response to receiving light from the rotatable light emitting diode 20 as the disc 12 and connected shaft 22 are rotated with respect to the stationary base 14.
- the plurality of photo resistors 34, 36, 38, 40 are supported within an EMF-resistant housing 42 within the base 14.
- Each photo resistor is operably connected to an output port 44, 46, 48, 50.
- An input port 52 is provided for operably connecting to each of the photo resistors 34, 36, 38, 40.
- the rotor disc 12 is positioned with the shaft 22 rotatably supported through bearing 32 by the stationary base 14.
- the disc 12 is rotatable in either direction by an operator in order to direct the corresponding sound being fed through the input port 52 to one or more of the output ports 44, 46, 48, 50.
- the shaft 22 can be elongated to include support through additional stationary bases for separate sound channel inputs to be directed independently to different photo resistor outputs with additional light emitting diodes directed in either the same direction as the light emitting diode 18, or in different directions offset at angularly spaced positions with respect to the directional LED 18.
- a two sound channel system could have directional LED's spaced 180° with respect to one another.
- a three sound channel audio distributor could include directional LED's spaced 120° with respect to one another.
- the number of sound channels can be modified as desired for the particular application, and the angular orientation of the directional LED's can be located at any angular orientation with respect to one another as desired.
- the audio distributor uses a very simple principle to effect the assignment of an audio signal to any one of a plurality of sound channels, by way of example and not limitation such as four or more sound channels.
- Four photo resistors which exhibit a very high resistive value in the dark, each receive the audio input signal.
- the other lead of each photo resistor is connected to one of the four output channels.
- the photo resistors are arranged in a light-tight circular container, facing in toward the center of the circle.
- a round shaft occupies the center of the circular space; at one side of the shaft, there is a light-emitting diode (LED) pointing out toward the perimeter of the circular space, towards the photo resistors.
- LED light-emitting diode
- the shaft with the LED is connected to a disc on top of the circular housing so that the user can spin the disc/shaft around, shining the LED on, or between, any of the photo resistors.
- the disc/shaft has free rotation because the batteries, switch, and wiring for the LED are recessed into the disc.
- the circular housing which includes the bottom of the device, remains stationary during use, since the housing supports a number of sound cables (XLR connectors) attached to the housing.
- the audio distributor functions as follows: when dark, the photo resistors exhibit sufficiently high resistance to the typically weak input signal from a microphone, guitar, preamplifier, or computer, so that the further conductance of the signal through the photo resistor and out to the power amplifier is effectively blocked. When some of the light from the LED reaches the photo resistor, the resistance drops proportional to the intensity of the light falling on the photo resistor, thus allowing relatively more or less of the audio signal to pass on to the amplification stage and to the speakers.
- a particular benefit of this method of audio distribution is that the transitions from one speaker to another are smooth, owing to the gradual rise and fall of the amount of light reaching the photo resistors.
- the response time of the photo resistors is quite short, so that the device allows good responsiveness to the actions of the performer.
