Abstract

A cordless headset for a mobile phone 22 makes use of a small add-on transceiver 21 that plugs into the mobile phone's external connectors 21. Another transceiver 11 fitted onto the headset picks up the signals sent by the transceiver 21 and is powered by small rechargeable batteries. The transceivers are a short-range frequency modulated transmitter/receiver type.

Description

2359689 1 CORDLESS HEADSET FOR THE MOBILE PHONE This invention relates to

a cordless headset of the type that operates on radio waves, a small frequency-modulated short range transceiver is used to pickup the signals from the phone and relay them to the earpiece (headset).

The concept is based on the concern that mobile phones emit microwave transmission as a fimction of their routine operation. As the phone is held in-unediately adjacent to the user's head, this puts one's brain to close proximity to these microwave signals. While still only speculative at this point, there is considerable concern that these microwaves could cause damage to brain cells, particularly when the user spends a great deal of time talking on a cellular phone and hence the user's brain is exposed to these microwaves over an accumulation of many hours. This risk can be offset to some extent through the use of a headset connected to the phone by a lead wire. However, this can be a cumbersome arrangement as the cable can easily become angled and can be particularly problematic, and even dangerous, when used while operating an automobile.

An object of this invention is to provide the mobile phone user with a means whereby routine conversations can be carried out without having to place the phone next to one's head and without the need for a trailing wire running from the headset to the phone. With this configuration, the user would suffer no health risks, as this would be a very low frequency transmission compared to the transmitter built into the phone, which produces high levels of microwaves.

Accordingly, this would be achieved through the use of a small add-on transceiver that would plug into the mobile phone's external connectors for the microphone, speaker and power point and another low voltage transceiver fitted onto the headset, which would be powered by small rechargeable batteries.

Also a small FM transceiver could be incorporated into the phone at the point of manufacture with the signals being picked up by the headset.

2 A preferred embodiment of the invention will be described with reference to the accompanying drawing in which:

FIGURE 1 shows the mobile phone with the transceiver.

FIGURE 2 shows the headset with the transceiver connected integral to the body of the unit.

3 As shown in Figure 1, the phone 22 would send out an analogue signal to the external speaker connectors 23. This signal would be picked up by the transceiver 21 and converted to a frequency-modulated signal; this signal would then be sent and be picked up by the transceiver 11 on the headset And passed to the speaker 12 of the headset.

As shown in Figure 2, this process is reversed when the output from the microphone 13 on the headset is passed to the transceiver 11, the signal is converted to a frequency-modulated wave and then sent to the transceiver 21 on the phone, which passes it on to the external microphone connectors 23 and then gets processed by the phone 22.
