The invention discloses a multifunctional demonstration pen
data transmission method and a multifunctional demonstration pen
data transmission product. The multifunctional demonstration pen
data transmission method comprises the following steps that: each kind of synchronous data is transmitted by dedicated channels;
asynchronous data are transmitted by one channel in a shared manner; and different
asynchronous data are packaged into data packets having different packet headers. The method can be compatible with the prior art and can ensure
response time. A multifunctional demonstration pen comprises a pen body, a pointer, an
audio signal collecting device, a
volume control device, a PPT control device, a
wireless receiving module and a
wireless transmitting module, wherein the pointer is arranged at the top of the pen body, the
audio signal collecting device is arranged at the bottom of the pen body, the
volume control device is arranged at one side of the pen body, the PPT control device is arranged on the surface of the pen body, the
wireless transmitting module is arranged inside the pen body and transmits audio signals,
volume control signals, PPT control signals and / or data signals, and the wireless receiving module is embedded in the pen body. The multifunctional demonstration pen can pick up sound in demonstration; and the multifunctional demonstration pen is advantageous in reasonable and comprehensive functions, and portable convenience.
