(not

The

 

IR

 

Headphone

 

Transmitter

 

Base

 

is

 

connected

 

to

 

an

 

External

 

Audio

 

Source.

The

 

Transmitter

 

Base

 

turns

 

the

 

sounds

 

produced

 

by

 

the

 

External

 

Audio

 

Source

 

into

 

a

 

series

 

of

 

pulses.

  

The

 

pulses

 

work

 

like

 

bits

 

in

 

a

 

computer,

 

digitally

 

capturing

 

the

 

sound

 

information.

 

These

 

pulses

 

are

 

then

 

sent

 

to

 

the

 

Transmitter

 

Base’s

 

infrared

 

(IR)

 

light

 

emitting

 

diode

 

(LED).

The

 

LED

 

is

 

a

 

device

 

which

 

produces

 

light

 

at

 

a

 

particular

 

wavelength.

 

The

 

infrared

 

LED

 

produces

 

long

 

wavelength

 

infrared

 

light.

 

It

 

can

 

not

 

be

 

seen

 

with

 

the

 

naked

 

eye,

 

but

 

works much

 

like

 

visible

 

light.

 

It

 

can

 

reflect

 

off

 

of

 

mirrors,

 

for

 

example,

 

and

 

can

 

be

 

blocked

 

by

 

any

 

objects

 

in

 

the

 

way.

 

Because

 

of

 

this,

 

infrared

 

headphones

 

can

 

only

 

be

 

used

 

when

 

they

 

are

 

within

 

a

 

line

 

of

 

sight

 

of

 

the

 

transmitter.

The

 

IR

 

Monitoring

 

Headphones

 

are

 

equipped

 

with

 

IR

 

sensors

 

(located

 

on

 

the

 

ear

cups)

 

that

 

pick

 

up

 

the

 

light

 

with

 

and

 

turn

 

it

 

back

 

into

 

sound.

 

The

 

IR

 

Monitoring

 

Headphones

 

have

 

an

 

infrared

 

cell,

 

which

 

produces

 

a

 

pulse

 

of

 

electricity

 

every

 

time

 

infrared

 

light

 

lands

 

on

 

it.

 

The

 

cell

 

is

 

designed

 

to

 

pick

 

up

 

the

 

particular

 

frequency

 

of

 

light

 

produced

 

by

 

the

 

Transmitter

 

Base,

 

so

 

it

 

is

 

not

 

disturbed

 

or

 

thrown

 

off

 

by

 

other

 

light.

 

A

 

small

 

computer

 

inside

 

of

 

the

 

headphones

 

takes

 

these

 

pulses

 

of

 

electricity

 

and

 

turns

 

them

 

into

 

an

 

audio

 

signal.

 

This

 

audio

 

signal

 

is

 

then

 

amplified

 

which

 

become

 

audible

 

sound.
