Choosing Design

Group discussion on 4 phone types

Chose Bell’s Magnetophone design

Reasons for choosing magnetophone:
Easiest to work with
 Could be easily improved upon
 Transceiver was more straightforward than the
receiver

Brainstorming

Weakness of Bell’s Prototype:
 Signal
strength very low
 Not portable

Proposed Improvements:
 Pass
current through coil
 Improved suspension system for the magnet
 Include soft-iron core
 Introduce a step up transformer into the design
Construction of Prototype

Decide and buy various material used in the
prototype

Build the base and outer shell

Build inner components of prototype
Testing & Development

On testing the prototype we discovered that our
signal strength did not match our expectations

Hence we made certain changes to our design:
 Modifying
the coil to be multilayered
 Use of an op-amp circuit to improve signal
strength
