In order to achieve the above object, the technical scheme adopted by the utility model is as follows: a kind of bluetooth multifunctional teaching auxiliary system based on smart phone, comprises mobile phone operating system and PC operating system, mobile phone operating system comprises PCM voice equipment, and described PCM voice equipment connects There is a bluetooth chip, and the bluetooth chip is connected with a protocol stack module, and the protocol stack module is connected with a wireless microphone, a remote controller and a file transfer module, and the PC operating system includes a USB bluetooth adapter, and the USB bluetooth adapter is connected with a hardware driver module , the hardware driver module is connected with a transmission module, the transmission module is connected with a protocol stack module, and the protocol stack module is connected with an interface display module and a virtual sound card module.

Further, there is a one-way connection between the PCM voice device and the Bluetooth chip.

Further, the Bluetooth chip is bidirectionally connected to the protocol stack module, and the protocol stack module is bidirectionally connected to the wireless microphone, the remote controller, and the file transfer module.

Further, there is a bidirectional connection between the USB Bluetooth adapter and the hardware driver module, a bidirectional connection between the hardware driver module and the transmission module, a bidirectional connection between the transmission module and the protocol stack module, and the protocol stack There is a two-way connection between the module and the interface display module.

Further, the protocol stack module and the virtual sound card module are unidirectionally connected.

The beneficial effects of the utility model:

The bluetooth adapter of the PC and the bluetooth module of the mobile phone of the utility model communicate through the bluetooth technology, and the use of bluetooth can cheaply and easily realize single-point to multi-point wireless data and voice transmission in a short distance, and the power consumption is low, and only a small Functions such as wireless microphone, wireless remote control and wireless U disk can be realized by investing in it. Compared with traditional equipment, its advantages are small investment, simple implementation, rich functions, and convenient use. It can be widely used in various occasions such as multimedia teaching and speeches. Therefore, the use of Bluetooth technology to realize multimedia-assisted teaching can overcome many problems of traditional equipment. defect.
