Introduction

This product use 1.5V / 150mA button cells as power supply. It enhances sound energy intensity and forwards to ears undistortionly through internal circuitIt need to change sound energy to electrical signal, enlarge the electrical signal, then change the electrical signal to sound energy. Input transducer is made of microphone, magnetic induction loop and so on, whose function is changing the sound energy to electrical signal, then send to amplifierThe amplifier enlarges the input electrical signal, then send to the output transducerThe output transducer is made of earphone or bone conduction vibrator, whose function is changing the enlarged electrical signal to sound energy or kinetic energy to output, to fit for deaf patient in various degrees.
