For a large-screen electronic terminal, such as a pad, it is inconvenient to hold it while making a call. If you put it on the table and talk to the electronic terminal, and listen to it through the hands-free speaker, you will lose all the benefits of the mobile communication device. If there are people around, you will hear the voice from the phone. The Chinese communication party does not want outsiders to hear the voice on the phone. All the problems mentioned above can be easily solved by adding earphone 150 (or called wireless earphone). A converted and played, users can hold a stylus to talk, which is lighter than a small feature phone.

As shown in FIGS. 3 and 4 , the stylus also includes a microphone 160 connected to the battery 110 and the short-range communication circuit 120 . The microphone 160 can be matched with the earphone 150, and when it is inconvenient to hold the communication terminal, the stylus can be directly used for talking. In addition, the microphone 160 can also be used for recording, karaoke and so on. Mobile terminals generally have a recording function, and high-profile devices also include audio and sound synthesis functions. When recording with a relatively bulky terminal, both the recorder and the recordee will inevitably be affected by the terminal, and recording with a small recording pen is much better for the physical examination of the recorder and the recordee. When users use their mobile phones to sing karaoke and mix and synthesize with music, it will be a very good experience to speak to the stylus shaped like a wireless microphone. After the microphone 160 performs A/D conversion on the received voice signal, the obtained audio file is cached in its own cache device, and then compressed and transmitted to the electronic terminal through the short-distance communication circuit 120 . It can improve the user experience when recording and sound synthesis.

The flashlight is a function that many mobile phones have, but the implementation is basically to turn on the screen to display white light. Displaying white light on many screens consumes a lot of power. The utilization rate of converting electric energy into light energy is low, and the mobile phone screen does not have a converging function. As a result, the mobile phone display screen is used as a flashlight, which consumes power and has a short effective irradiation distance and weak light intensity. In the utility model, several miniature light-emitting diodes are installed at one end of the stylus, and when the flashlight button 104 is pressed, the light-emitting diodes can be made to emit light to realize the function of the flashlight. Light-emitting diodes have the characteristics of high efficiency, energy saving, and good brightness in lighting.

Thermometers are a good helper in our lives, but the safety problems of mercury thermometers, the accuracy and carrying problems of infrared thermometers make it impossible for us to carry thermometers. Adding a thermometer function to the stylus can perfectly solve this problem, so that we can obtain accurate body temperature information at any time. From the modeling point of view, the stylus is naturally suitable for measuring body temperature. A digital temperature sensor 190 is arranged on the stylus, and after obtaining the temperature value, it is transmitted to the electronic terminal for display through the short-distance communication circuit 120 . The digital temperature sensor 190 can periodically send the temperature value to the electronic terminal. When using this thermometer to measure body temperature, the temperature can be read from the electronic terminal without taking the thermometer out of the side of the body, and the real-time information of the body temperature after the thermometer is put in can be displayed on the screen. The rise will not fall, the real-time body temperature cannot be displayed, and the thermometer needs to be taken out, and the thermometer must be shaken vigorously next time. The toxicity of mercury is always a hidden danger. The thermometer function of the stylus can conveniently solve these problems.

As shown in FIGS. 3 and 4 , the housing 100 is also provided with an SOS button 105 connected to a controller 140 , and the controller 140 is connected to a light emitting diode 180 and a laser emitter 170 . For users who like outdoor activities, the SOS function may play a role in saving lives and gaining time. In the utility model, the SOS button 105 is connected with the light-emitting diode 180 and the laser emitter 170 via the controller 140 to increase the SOS function for the stylus. The class management 180 sends distress signals in SOS rhythm in turn. The diameter of the signal sent by the light-emitting diode 180 is larger, which can better attract nearby rescuers; the laser transmitter 170 has strong directivity and penetrating light, and can attract the attention of rescuers who are a little farther away. The SOS mode combined with flashlight and laser can have a better effect of calling for rescue.

As shown in FIG. 4 , the stylus also includes a memory chip 200 connected to the controller 140 . The communication interface of the memory chip 200 may be a standard short-range wireless communication standard, such as a wireless USB protocol. At this time, the stylus can be used as a portable wireless U disk, and the memory chip 200 can also be directly used to save files during recording and mixing.

As shown in FIG. 4 , the earphone 150 and/or the microphone 160 are connected to the controller 140 . When the earphone 150 and the microphone 160 are connected to the memory chip 200 via the controller 140, the microphone 160 can store the audio file into the memory chip 200 via the controller 140, and the earphone 150 can play the audio file that the controller 140 extracts from the memory chip 200 . This connection method can also realize the reverse lookup function. Users who use a stylus often have such an experience: they don't know where the stylus just used has been put away. Since the user handles several things at the same time or has urgent matters to deal with during use, it is likely to place the stylus in a very close place, but cannot find it when it is needed. In order to solve this problem, the utility model adds a reverse search function. When the electronic terminal starts the reverse search application, the short-distance communication circuit 120 of the nearby stylus can receive the search instruction from the electronic terminal, and then send the search instruction to The controller 140, the controller 140 can make the light-emitting diode 180 and the laser emitter 170 flash intermittently according to a preset method, and simultaneously extract a specified audio file from the memory chip 200, so that the earphone 150 can emit a specified sound intermittently. Because the distance between the position where the stylus is generally placed and the user is not too far, the user can find the stylus according to the sound and light signal sent by the stylus, and realize the reverse search function.

Preferably, the laser button 103 , the flashlight button 104 and the SOS button 105 can be multiplexed with the remote control button 101 . For example, short press the remote control buttons 101-1, 101-2, and 101-4 in Figure 4 to realize their remote control functions respectively, and long press the remote control buttons 101-1, 101-2, and 101-4 to realize laser pointer, flashlight, SOS, etc. Function.
