隨著智慧型手機越來越普及，無線通訊的應用層面也越來越廣泛。目前常見於手機的無線通訊裝置可透過藍芽無線通訊方式傳輸訊號，而藍芽無線通訊技術大致有兩種資料傳輸類型，分別是非同步非連接連結模式( Asynchronous Connection-Less, ACL)和同步連接導向模式( Synchronous Connection-Oriented Link, SCO)，ACL是不使用預留時槽(Time Slot)的封包導向的傳輸模式，而SCO是使用預留時槽的電路導向傳輸模式。With the increasing popularity of smart phones, the application level of wireless communication is becoming more and more widespread. At present, the wireless communication devices commonly used in mobile phones can transmit signals through Bluetooth wireless communication. Bluetooth wireless communication technology has two types of data transmission, which are asynchronous connection-less (ACL) and synchronous connection. Oriented mode (Synchronous Connection-Oriented Link, SCO). ACL is a packet-oriented transmission mode that does not use Time Slot. SCO is a circuit-oriented transmission mode that uses Reserved Time Slot.
但是，目前應用上述藍芽無線通訊的無線通訊裝置大多皆為一對一的配對方式，例如使用者透過藍芽耳機只能自己單獨聽音樂與接聽來電，其功能較為侷限且運用效果較為單調。However, most of the current wireless communication devices using Bluetooth wireless communication are one-to-one pairing methods. For example, users can only listen to music and answer incoming calls by themselves through Bluetooth headsets. Their functions are more limited and the application effect is monotonous.
因此，本發明的主要目的乃在於讓使用者透過自己本身的手機與各種形式的耳機麥克風，即可達成多人群組通話及聊天的技術功用。Therefore, the main purpose of the present invention is to allow users to achieve the technical functions of multi-person group calls and chats through their own mobile phones and various forms of earphones and microphones.
