摘要
由于当今无线技术的进步,无线耳机的普及和广泛使用,怎么才能更好的发挥它的优越作用,提升无线耳机的产品质量和功能。达到普遍使用的领域,触发消费者对这项产品的爱好与普遍应用。
本课题研究开发的无线耳机可以应用在许多方面,比如用无线耳机接听手机电话,省却了耳机电线,同时免除了存在争议的手机辐射问题。还可以用于智能系统中的无线通信,比如近几年盛行的足球机器人比赛,机器人之间为了配合而互相通信以及主机为了作全局指挥与机器人之间的通信就需要无线耳机。所以我们相信无线耳机是有很宽广的市场前景的。
毕业设计的目的是了解基本电路设计的流程,丰富自己的知识和理论,巩固所学的知识,提高自己的动手能力和实验能力,从而具备一定的设计能力。
我做得的毕业设计注重于对多接收无线耳机理论的理解,明白它的工作原理,以便以后单片机领域的开发和研制打下基础,提高自己的设计能力,培养创新能力,丰富自己的知识理论,做到理论和实际结合。

Abstract
Because today's wireless technology progresses, the popularity of wireless headsets and widely used, how it might best superior function, improve the quality of products and wireless headset functionality. Achieve widespread use of the field, trigger consumer interest and this product applies generally.
This topic research and development of wireless headset can be applied in many aspects, such as using wireless headset answer phone call, dispense with headphone wires, and absolved the controversial mobile phone radiation problems. Can also be used in intelligent system of munications, for instance in last few years popular er robot, robot race between each other in order to coordinate munication and host to be munications between mand and robots need wireless headset. So we believe that the wireless headset is a very broad market prospect.
Graduation design is to understand basic circuit design process, enrich their knowledge and theory, consolidate of knowledge, improve their ability and experiment ability, thus have a certain design ability.
I do a graduation design focuses on wireless headset for receiving the theory of understanding, understand how it works, so that later MCU development and the development area, thus laying a foundation to improve their design ability, cultivate the innovative ability, enrich their knowledge theory, do with theoretical and pr
