A combined type personal handphone system multimedia teaching device with a wireless headset and a microphone relates to a multimedia teaching device. The combined type personal handphone system multimedia teaching device with the wireless headset and the microphone comprises an interactive electronic whiteboard and is characterized in that the wireless headset is electrically connected with a microphone circuit; signals wirelessly transmitted between the wireless headset and the microphone are received and sent by the interactive electronic whiteboard through radio waves; the interactive electronic whiteboard is electrically connected with a personal handphone system; a telecommunication wireless transmission device is electrically connected with the personal handphone system; and the interactive electronic whiteboard is electrically connected with a telecommunication wireless transmission device. As the signals wirelessly transmitted between the wireless headset and the microphone are received and sent by the interactive electronic whiteboard through radio waves; when the wireless headset and the microphone are combined with the interactive electronic whiteboard for use, the synchronous receiving can be realized; when the interactive electronic whiteboard is combined with the personal handphone system for use, all writing operations of teachers on the interactive electronic whiteboard are timely fed back to the personal handphone systems of students through the wireless transmission technology of the telecommunication personal handphone system, thereby the students are convenient to learn and summarize.
