Embodiment 1

[0051] This embodiment provides a wireless control method that can be used for a mobile phone with a projection demonstration function (referred to as a projection mobile phone) to control projection and display content, which is convenient for users to use this function and improves the use effect of this function.

[0052] Specifically, the mobile phone used for demonstration projection in this preferred embodiment may include two parts: a Bluetooth earphone and a projection mobile phone. Among them, the Bluetooth headset includes: a wireless communication module, which is responsible for the pairing and wireless communication between the Bluetooth headset and the mobile phone, and is a channel for voice and data transmission between the headset side and the mobile phone side; the voice module, including the microphone and speaker of the Bluetooth headset, used for Responsible for sound collection and playback; key input module for answering / hanging up calls and controlling t...

Embodiment 2

[0056] This preferred embodiment provides a wireless control method for a demonstration projection mobile phone, and realizing the function of controlling the projection demonstration content includes the following steps:

[0057] Step 1: The wireless module on the earphone side is normally connected to the wireless module on the mobile phone side to establish a data transmission path.

[0058] Step 2, when the mobile phone is in the normal standby mode, the baseband software module of the mobile phone recognizes the key input of the Bluetooth headset as a normal function input, and can control the answering / hanging up of the incoming call and the adjustment of the volume of the call.

[0059] Step 3, when the projection mobile phone starts the demonstration function, the baseband software module switches to the projection demonstration mode, and recognizes the button input generated by the Bluetooth headset as a control command input by the user, which is used to control the s...

Embodiment 3

[0065] Figure 5 It is a bluetooth earphone schematic diagram for demonstrating the control method of the projection mobile phone according to the third preferred embodiment of the present invention, as Figure 5 As shown, the main components of the Bluetooth headset are decomposed and marked with 1-5 respectively: 1 indicates the answer / hang up button of the Bluetooth headset; 2 indicates the volume adjustment button of the Bluetooth headset; 3 and 4 indicate the Bluetooth The microphone and earpiece of the headset; 5 indicates the body of the Bluetooth headset. In addition, the bluetooth headset may also include an internal circuit and a wireless transceiver module.

Abstract

The invention discloses a control method and system for projection demonstration of a mobile terminal, and the mobile terminal. The mobile terminal comprises a wireless earphone, and a base-band chip located in a terminal machine body, wherein the wireless earphone is used for transmitting a control command, which instructs the terminal machine body to carry out projection demonstration on an electronic file, to the terminal machine body through the wireless connection with the terminal machine body; and the base-band chip is used for receiving and using the control command to operate the projection demonstration process of the current electronic file. According to the invention, the system has enhanced flexibility and can improve the user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular to a control method, system and mobile terminal for projection demonstration of a mobile terminal. Background technique [0002] With the rapid development of modern communication and electronic technology, the functions of mobile phones are not limited to traditional calls and text messages. More and more multimedia, network and other functions are integrated into mobile phones, which expands the scope of use of mobile phones and brings great convenience and more fun to daily life. Among the applications in the field of mobile phones today, the projection presentation function is one of the research hotspots, that is, by integrating optical and electronic devices on the mobile phone, the mobile phone can have the same projection presentation function as ordinary projector equipment, which is portable, flexible, safe, etc. advantage. [0003] In the related art, a functional stru...
