Mobile phone and hands-free kit with inductive link
First Claim
1. A mobile phone having a transmitter coil forming a first part of an inductive link for forwarding sound signals received by the mobile phone and an earpiece for fitting into an ear canal and having a housing of which at least a proximal portion can fit within the ear canal, said housing comprising:
- a receiver coil forming a second part of the inductive link for receiving sound signals from the transmitter;
an amplifier for amplifying the sound signals received by the receiver coil, the amplifier having a means responsive to received signal level for squelching its output at low levels of detected signal;
a transducer for reproducing the received sound signals; and
a space for a battery.

Abstract
A mobile phone has a transmitter coil forming a first part of an inductive link for forwarding sound signals received by the mobile phone and an earpiece for fitting into an ear canal and having a housing of which at least a proximal portion can fit within the ear canal. The housing contains a receiver coil forming a second part of the inductive link for receiving sound signals from the transmitter, an amplifier for amplifying the sound signals received by the receiver coil, a transducer for reproducing the received sound signals; and a space for a battery. The amplifier has means responsive to received signal level for squelching its output at low levels of detected signal.
