IC chip type hearing aid module for mobile communication terminal
First Claim
1. An IC (integrated circuit) chip type hearing aid module having a hearing aid circuit, comprising:
- a first section to increase a magnetic intensity produced in an ear speaker, and connected in series on a first output line between a mobile communication terminal and the ear speaker;
a second section to increase a magnetic intensity produced in the ear speaker, and connected in series on a second output line between the mobile communication terminal and the ear speaker;
a third section to compensate a tolerance generated by mutual interference between the second section and the first section, and connected in series between an input terminal of the first section and an output terminal of the second section; and
a fourth section to compensate a tolerance generated by mutual interference between the second section and the first section, and connected in series between an input terminal of the second section and an output terminal of the first section.
