Abstract

The noise reducing headset converter connects a headset to the equipment with which it is to be used. The converter receives the unwanted ambient sound from the surrounding environment, analyses it and produces an opposing signal. This signal is fed into the headphone circuit of the headset, and acts in opposition to the ambient sound penetrating the headset earphones. This has the effect of reducing the unwanted noise being heard by the user. It enables the user to employ his existing headset with a reduction in noise levels without the expense of purchasing an entirely new headset with the noise-reducing or noise cancelling facility. <IMAGE>

Description

NOISE REDUCING HEADSET CONVERTER.
The invention relates to an electronic device that converts a conventional headset into a noise reducing headset.
Headsets are well known items of essential equipment in the fields of aviation and maritime communications. They comprise a pair of ear cups containing audio emitting componants (ear phones), connected by a frame that fits over the wearer's head. A microphone, fitted to a boom, is incorporated into the structure. An electrical cable (or cables) onto the end of which is a plug, is wired into the headset, so that it may be plugged into the equipment that the operator wishes to use.
Recent technical developments have enabled manufacturers to build into the design (usually onto the electrical cables) a box of electronic componants which analises ambient noise, processes the signal and sends an opposing signal through the earphone cable to cancel the ambient noise.
The noise reducing headsets are reletively expensive and if used render any conventional headset already possessed unusable.
According to the present invention, there is a separate and independant box containing the electronic circuitry for the noise reduction. Within the design is a means of connecting it to the equipment with which it is to be used, and a further means of connection to a conventional headset.
Incorporated into the box is a microphone, sensitive to ambient noise, which the electronics process and send the opposing signal through the earphone cable.
A specific embodiment of the invention will now be described by way of example with refence to the accompanying drawing which shows, in perspective, the box with the relevant connections and apparent componans.
Referring to the drawing, the invention comprises a box 1, made from a non-conductive material, with removable access panel (not shown). This box contains the electronic componants necessary for the operation of the-invention.--A microphone 2 is incorporated within the box in a suitable position to detect ambient noise. The noise signal is processed by the electronic circuitry within box 1 and an opposing signal produced.
To one end of the box 1 are a pair of sockets 3, one of which accepts a headset microphone plug and the other accepts a headset earphone plug.
The signal, once processed by the electronics, is sent to the headset earphones via one of the sockets 3. The sdckets 3 may be placed in any convenient position on the box 1. On the opposite end of the box 1 are a pair of plugs 4. These enable the invention to be connected to the equipment which the operator intends to use. The plugs may be on any length of cable, or rigidly connected to the box 1. An internal power supply (batteries) may be included, and a battery access plate 5 is shown. Provision for an external power supply may be included (not shown).
An on/off switch 6 and power supply indicator 7 (light or gauge) may also be included in the design. A clip or alternative securing device (not shown) may.-'be fitted to the box 1.
Once the ambient noise has been processed and sent to the headset earphone, the unwanted noise level within the users earphones will be reduced.

Claims (7)

CLAIMS.
1. A noise reducing headset converter comprising a box of electronic circuitry and componants necessary for the receiving of ambient sound, analising and processing it, and transmitting a suitable opposing signal to the users connected equipment, and incorporating an internal power source.
2. A noise reducing headset converter as claimed in Claim 1 wherein a means of connection to the users existing equipment is provided by means of a plug or plugs and a socket or sockets, built into the structure.
3. A noise reducing headset converter as claimed in Claim 1 or Claim 2, wherein the plugs and sockets are on flexible cables of any length which are connected to the device.
4. A noise reducing headset converter as claimed in Claim 1 or Claim 2 or Claim 3, having an external power source, with the means of connection to the device.
5. A noise reducing headset converter as claimed in Claim 1 or Claim 2 or Claim 3 or Claim 4, having a means of securing the device to a suitable point within the immediate environment.
6. A noise reducing headset converter as claimed in any preceding claim, but incorporating an on/off power switch.
7. A noise reducing headset converteras claimed in any preceding claim, but incorporating a power supply indicator.
