Abstract
This invention relates to Bluetooth earphone. Existing Bluetooth earphones have some problems: users must wear the earphone to use it, so that the user will feel uncomfortable if the user uses the earphone for a long time. In order to solve these problems, this invention has added a speaker with larger power (i.e. 3W) and configured corresponding speaking amplifying circuit and switching circuit based on the existing Bluetooth earphones. With these new features, the user can adjust his/her Bluetooth earphone by switching different circuit so that it can work in earphone mode or speaker mode. When the Bluetooth earphone works in speaker mode, the user can hear normal voice without wearing the Bluetooth earphone. Obviously, this new invention can be used not only as a common earphone, but also as a speaker. In addition, a call identification circuit, a Bluetooth transmitting circuit and a microphone can be added to expand functions of the whole Bluetooth earphone. As a result, it can be used as a Bluetooth telephone receiver/transmitter cooperated with the fixed telephone or mobile phone.
