Description

mobile phone with multifunctional headset

technical field

The utility model belongs to the technical field of portable communication terminals, and more specifically relates to a mobile phone with a remote controller arranged on an earphone.

Background technique

Now people pay more and more attention to health problems, so people who often use mobile phones pay more and more attention to the electromagnetic radiation problem generated in mobile phone calls. In order to keep the mobile phone away from the human head and make it easy to use, users choose to use earphones. And because the mobile phone with MP3 playing function is popularized day by day, the usage amount of earphone increases greatly, and the number of times that the user uses earphone is also more and more frequent, and earphone has become the must-have standard configuration on a mobile phone.

However, the current mobile phone earphones can only realize the simple functions of single button and voice transmission. If you want to make a call, check incoming calls and other simple functions on the mobile phone, even if you are using the earphone, you can only view it from the mobile phone. And now there are very many mobile phones with the function of built-in MP3 player, and the operation when using this function requires the control of the mobile phone itself to complete. Since the current headset can only answer calls, users who want to check incoming call records and play MP3 music still need to take out their mobile phones to perform functional operations, which is very inconvenient.

Contents of the invention

The purpose of this utility model is to solve the limitation that the headset on the current mobile phone can only answer the phone and cannot perform other functional operations, and provides a mobile phone with a multi-functional headset. A control unit is added to the headset to realize the basic function of the mobile phone. Functional remote control enables users to operate conveniently.

In order to achieve the above object, the utility model includes a mobile phone, an earphone connected to the mobile phone through an earphone interface, the earphone interface includes a data bus and a sound bus, and the earphone also includes a remote controller connected to the mobile phone through the data bus, and the remote control The display screen and buttons connected to the device, as well as the microphone and earpiece connected to the mobile phone through the sound bus.

The earphone interface needs to transmit data information and sound information, and a standard 10-pin interface is selected. The mobile phone includes a 10-pin interface slot, and the earphone includes a 10-pin interface plug.

The remote controller on the earphone is a single-chip microcomputer with an I ² C bus, and the single-chip microcomputer of the 87LPC762 model of Philips is adopted. Due to volume and weight requirements on the headset, both the display and buttons need to be miniaturized. The display uses a 16×64 two-color LCD display, and the keyboard area on the headset has 4 buttons.

The utility model can be widely applied to various mobile phones, and the user of the mobile phone can complete the common operation of the mobile phone through the remote controller of the earphone, which increases the usability of the mobile phone product.

Detailed ways

As shown in Figure 1, it is a schematic diagram of the overall structure of the mobile phone and the earphone. The earphone 2 is connected to the mobile phone 1 through the earphone jack 3. The communication between the earphone 2 and the mobile phone 1 includes a sound bus and a data bus. The bus arrives at the earpiece to play voice and MP3 data, and the voice of the mobile phone user is converted into an electrical signal through the earphone microphone, and is transmitted to the mobile phone 1 for processing through the sound bus.

The earphone 2 in the utility model also includes a display screen 2-2 part, a button area 2-3 part and a remote controller 2-1. Since the earphone 2 needs to be easy to carry and the controller on the earphone does not need to realize particularly complicated functions, and is limited by weight, the display screen 2-2 does not need to be too large, and the pixel point can be selected as 32*64 or 16. ×64 ordinary two-color LCD liquid crystal display, 4 buttons are set in the 2-3 part of the button area to realize common function operations.

As shown in Figure 2 and Figure 3, the remote controller 2-1 of the earphone has a built-in single-chip microcomputer, and the single ^- chip microcomputer of the 87LPC762 model of Philips can be selected. ² The C bus is in slave mode, receiving the data transmitted by the mobile phone. The LCD data and sleep control data sent by the mobile phone are directly transmitted to the microcontroller through this I ² C bus.

The 2-3 part of the button area is set with 4 buttons, and the user can realize the common function operation through the buttons. If there is a button event, the GPIO P0.0 of the single chip microcomputer sends a signal to the processor of the mobile phone, and the processor of the mobile phone passes the I ² C bus Read keystroke data and process it.

The LCD display 2-2 and button area 2-3 on the headset are controlled by a single-chip microcomputer. The LCD interface is in the SPI bus mode. The single-chip microcomputer initializes the LCD when the console is powered on, and transmits the display data transmitted by the I ² C bus during normal operation. Refresh to LCD. The keyboard uses array scanning to read key information, and only processes one key message at the same time. The single-chip microcomputer itself does not process data. After the earphone is plugged in, the mobile phone sends display data to the single-chip microcomputer according to its own corresponding state. The mobile terminal, the mobile terminal responds to the event processing according to the button information.

Some mobile phone functions can be operated through the LCD display and buttons of the earphones, and some common operations of users can be realized, such as displaying and checking time, signal, battery power, phone book, call records and text messages, incoming calls, making calls, selecting music, and realizing music Play various controls and other functions. These commonly used operations are completed through the remote controller of the headset, which can reduce the usage of mobile phones and increase the usability of mobile phone products.

The power supply of the remote controller 2-1 in the headset is provided by the mobile phone 1, so that the mobile phone can choose whether to supply power to control the power consumption of the single-chip microcomputer.

As shown in Figure 4, the earphone interface 3 between the mobile phone 1 and the earphone 3 needs to adopt a 10-pin interface due to the increase of data communication. Among them, CON1 adopts a standard 10-pin interface slot, which is a standard device, and the pin definition is the same as that of the earphone connector. correspond. CON2 is the connection mode of the earphone cable, which can be connected to the earphone receiver and the microphone (pins 1~4) and the remote controller (pins 5~9) respectively through the pin definition. The mobile phone 1 is used to control the communication connection with the earphone 3 .
